Tube bending machines

2012-02-14T06:28:00.000-08:00

Pyramid type bending machine with 3 driving rollers having variable centre distances.

The adjustable geometry of this machine makes it possible to bend an extremely wide range of section bars and is widely used especially in the construction of window/door frames in aluminium or other material, in steel structure work and many other fields of activity.

The upper roll is hydraulically adjustable whereas the seat of the lower rolls can be adjusted in four different positions of hydraulic pipe bender.

-Wide centre distance: optimal bending of square and rectangular tubular section bars, and special section bars for closed-section window/door frames.

-Medium centre distance: optimal bending of round tubes with the right compromise to obtain very small radii without ovalising.

-Narrow centre distance: optimal bending of thin and asymmetrical section bars with maximum limitation of warping ensuring driving under any condition.

Other important features:

-Mechanical clutch device on upper roll to offset surface speed.

-Tippable base-plate to work in horizontal and vertical mode

-Rotating parts mounted on bearings and constructed in casehardened ground high alloy steel

-Machine body in steel

-Electric cabinet and hydraulic power pack incorporated in the machine.

-Wide range of accessories available upon request to permit the machine to bend any type of section bar.

- Mobile control console containing machine and interpolated computerized numeric control CNC tube benders.

Development of a control that was already amazing and is now absolutely astounding.

Simply because until now such a simply beautiful, simply intuitive and simply complete program had never been seen. Industrial computer on Windows platform able to manage two or more interpolated axes with an indescribable progression and precision.

15” Touch-screen monitor. Intuitive system to program any type of regular and/or irregular geometry designing it directly on the screen.

”dxf” file importation with possibility to modify shape to bend on the screen, directly dragging the ends of the segments to lengthen or shorten them, or clicking on the arrows to enlarge or reduce the bending radii; all the operations are acknowledged by the “bending4program” that updates in real time. In conclusion the shape we see on the screen, and that we can measure with the specific tools, is really the actual shape that the machine will produce. Completely automated management of passage from straight section to bent section. A group of algorithms that, calculated according to the machine geometry, the profile section and the shape to be obtained, produce harmonious and imperceptible association of tubing bender with perfectly symmetrical shapes.

New bending machine: advantages

2012-01-23T07:12:00.000-08:00

Versatility of bending machine, that can bend large size profiles, as well as profiles with small dimensions and radii, with its combination of considerable useful length and elevated stiffness of the supported shafts with a centre distance between the bending rolls having a wide variability range due to the converging straight-line guides.

Longer machine life because of the optimal distribution of the forces. Hydraulic pipe bender adjustment of the bending axes speed makes it possible to position the rolls with maximum precision. For example, during multi-pass bending, it is possible to rapidly approach the required radius and the subsequently finish the bending with maximum precision finely adjusting the position of the bending rolls. A longer life of the machine because of the optimal distribution of the forces.

The excellent geometry of the Alpha series, permits, with the same performance as a bending machine of the competition, considerable energy saving (on average the power required is halved).

Square tube bending has an innovative multi-axis positioner that permits a completely independent handling of the moving parts of the bending machine where it is applied.

The operator interface is incorporated in a panel of appropriate dimensions, that encloses in a single instrument all that is necessary to ergonomically manage the bending machine, avoiding confusing and bewildering indications caused by many devices spread out over the machine. The PQ10 is the latest electronic interface, designed specifically to meet the management requirements of pipe bending machines with more than 3 separate axes. With the touch-screen display and the Microsoft Window. CE operating system the use of the multiple PQ10 applications are intuitive and fast .

sequential multi-positioning of axes, used to carry out the movement of several axes continually and in sequence up to the required dimensions.

It is possible to set up to a maximum of 10 dimensions for each axis; the control electronics permit positioning of the bending axes with a precision of 0.1mm, whereas for auxiliary axes the precision is 1mm.

Possibility, at any time, to rotate the machine synoptic panel by 180°, to adjust the screen to the requirements of the operator.

The PQ10 also includes an advanced analysis system for self-diagnosis of any failures and/or maintenance operations on the control circuit. When necessary a warning is displayed with a description of the failure and a photo of the area requiring attention.

Upon request the metal bending machines can be supplied with a tele-assistance system for prompt service in any part of the world.

INNOVATIVE CONTRUCTION PHILOSOPHY IN BENDING MACHINE

2012-01-23T07:06:00.000-08:00

In a globalised world it may seem trivial to underline the origin of a product, but nowadays it’s important to assure clientele that entire production is all studied, designed and assembled in Italy. Especially in these times of worldwide crisis in industry it is important to point out that the company has continued to develop, refurbishing with a new high quality management system, SAP, worldwide leader in software solutions for business. Furthermore, a lot of energy has been spent in finding new technical solutions in the manufacture of the machines, in testing new products for special processing and in continual updating of the CNC-i numeric control–core and real added value of all bending machines.

LAMIERA 2010 exhibits a synthetic but significant series of high quality products manufactured by the company that has been UNI ISO 9001 certified for many years. The construction principle applied by most manufacturers consists in two angle rolls, mounted on pivoted levers on a central pin, that follow an orbital path, a third fixed roll overlays these two rolls, in a central position in relation to the other two.

CNC bending machines geometry is very common because production costs are less. However, this system has certain equally evident drawbacks, due to the forces involved, that subject the structure to considerable stress concentrated in a single point: the central pin. This is the weak point of the entire system, because, even if largely over-dimensioned , it will never have the necessary stiffness to ensure an even distribution of the stress it is submitted to.

The company has built and patented an innovative drive and support system of the roll-carrier shafts on slides with a linear stroke, which is much more precise and stiff than the system previously described. To this important development the possibility is added to be able to apply independent supports, that restrain the ends of the shafts greatly restricting deflection. The slides with their straight-line stroke act as the base to assemble the supports, so that also during adjustment of the slides, the shafts are always rigidly restrained on three points.

Possibility to bend section bars with a double pipe bending strength, compared to a bending machine with conventional drive system at the same cost.

The possibility to have an immediate saving on the purchase of a bending machine, which is much smaller, but appropriately dimensioned for the steel bending needs required.

Considerable saving on cost and on the handling of fixtures, much less cumbersome and with higher dynamics in the operations.

Requirements in tube bending

2011-09-28T09:50:00.002-07:00

The three principal requirements in tube bending are simply: machine, operator and tooling.

All three factors must be especially good to work with thin wall tubing on tight radii. Too many facilities still depend on the operators genius to compensate for near useless tooling. Poor tooling results in longer set-up time, scrapping of expensive tubing, poorly bent tubes and fail to produce an acceptable pipe bender. Highly competitive custom tube bending companies realize cheap and inferior tooling is the most expensive they can buy. Interlock tooling represents the ultimate in tube bending tooling. Complete interlock tooling, although developed and successful for numerical control tube benders, has proven advantageous for conventional machines. Each tool of the matching set is laterally locked in alignment. The clamp die is keyed and locked to the bend die, the wiper die located and locked to the pressure die, and the pressure die in turn is locked in alignment to the bend die.

Field reports have confirmed several advantages of interlock tooling. The clamp die, with all the hydraulic pressure available to it, will not crush or even mark the tube, thereby providing vastly improved gripping properties. Bend die and pressure die marks on the top and bottom of the tube are completely eliminated. In 23 instances tested, set up averaged one-third the time allotted for conventional tooling. A 32% reduction of scrap was recorded over previous runs using conventional tooling.

The five pieces of tooling (bend die, pressure die, wiper die, mandrel and clamp die) must all be close-tolerance excellent tooling. The bend die should have a maximum run out at the bottom of the bend groove of not more than . To help prevent tooling marks on the top and bottom of the tube bending machines, the bend groove should be deeper than half the tube diameter. The bend groove should be dead round and the diameter should measure 10% timeís wall thickness over tube diameter. The clamping area, unless cleated or with other provision such as flaring, beading, etc., should be three to six times tube diameter with a sandblasted or rough finish. The diameter of a clamp area should not be undersize more than 10% of wall thickness. Grip or pinch clearance should be held to a minimum. To permit the bend die to be used on right and left hand machines, the counter bore and keyway often are machined on both sides of the die. Centerline height must be maintained for both sides.

BENDING WITH BALL MANDREL AND WIPER DIE

2011-09-28T09:48:00.000-07:00

When the radius of the bend is smaller and/or the wall is thinner, it becomes necessary to use a

ball mandrel and wiper die. The wiper die is used to prevent wrinkles. The ball mandrel performs like a plug mandrel. The balls are used to keep the tube from collapsing after it leaves the mandrel shank.

Bending issues are enlarged when making tight bends or with thin wall tubing. It becomes more difficult to retain the material during compression.

The pressure is so intense the material is squeezed back past tangent and buckles. This area must be supported so that the material will compress rather than buckle; this is the prime purpose of the wiper die. Note, the wiper die cannot flatten wrinkles after they are formed; it can only prevent them.

Bending thin wall tubing - requirements for the bending of thin wall tubing with tight radius bends of centerline radius equaling the tube outside diameter have become more common in recent years.

To increase the problem, new alloys have been developed that are extremely difficult to bend. The proper bending machine, good tooling, and a trained operator can make all the difference.

To facilitate this type of tube bending, the material to be bent should receive special consideration. To help maintain the consistency of the tubing dimensions and characteristics, the entire material required for a given job should be acquired from one supplier, preferably even from the same lot or heat number. Premium-priced close-tolerance tubing should be considered. It often saves many more times its added cost. It may be necessary on occasion to size certain tubing before bending.

There are many pipe bending machines but only a few are capable of thin wall, 1 x D bending.

Even those machines best suited for this special bending must be in excellent condition and of a size large enough to assure rigidity. The machine must be capable of retracting and advancing the mandrel with the clamp and pressure dies closed. A hydraulically actuated pressure die is desirable. One feature of this system is that it provides identical pressure on the tube regardless of wall variation.

A pressure die boost counteracts the drag of the pressure die, mandrel and wiper die. It pushes the tube into the bending area, preventing excessive wall thin out.

Without a pressure die boost, the thinning that normally can be expected is about three quarters of the elongation of the outer wall. Companies specialized in steel bending automation for a broad array of fabricated products, includes CNC tube benders, tube measuring equipment and complete cellular integrated systems.

BENDING TUBE

2011-09-28T09:45:00.000-07:00

A bend die, clamp die, and pressure die are the minimum essentials for tube bending. The bend die helps to prevent the tube from flattening and forms a given radius of bend.

The clamp die holds the tube in position while bending. The pressure die forces the tube into the bend die.

Springback is excessive when a mandrel is not used. This should be considered when selecting a bend die. Springback is the term used to describe the tendency of metal that has been formed to return to its original shape. Springback will cause the tube to unbend from two to ten degrees depending on the radius of bend, and may increase the bend radius of the tube. The smaller the radiuses of bend the smaller the springback.

The tube may kink or buckle, this may be due to hard material which will not compress on the inside radius of the bend. The material, not being able to compress, pushes in toward the centerline of the tube. This condition can be corrected (provided the tube is not too hard) by proper set up of the tooling. A plug mandrel is indicated if the tube buckles and is still within the wall factor and the diameter of the bend.

The purpose of a plug mandrel is to prevent the tube from flattening and to bend without wrinkles or kinks. The mandrel is held in a fixed position while the tube is pulled over it. The tube stretching process is localized on the outer radius of the bend and the material is work hardened to retain its shape and not flatten. The material stretching is done on the forward tip of the mandrel. This force, acting on the mandrel tip, supports the inner radius of the bend, holding it firmly into the bend die groove. CNC bender is used on CNC benders from 0.25" inch to 6" inch tube bending machines.

The pressure die should be adjusted for a light pressure against the tube. The purpose of the pressure die is to keep the tube against the bend die through the duration of bending. The pressure die also keeps the mandrel from bending and maintains a straight tube between tangent points of bends (the portion of ubing left on the mandrel after steel bending). The location of the mandrel affects the amount of springback. The mandrel in a forward position (toward tangent) will stretch the material on the outside of the bend more than is necessary. This increases the length of material on the outside beyond that which is required to make a bend. When the bent tube is removed from the bend die, it will conform to the die and there will be little or no springback.

TUBING BENDERS

2011-09-28T09:44:00.000-07:00

Tubing benders come in many sizes, for use in everything from heavy construction to auto building to home landscaping. They range from a 16-ton hydraulic pipe bender to a handheld bender for small-gauge copper and aluminum tubing. All of them, however, use one of four basic methods. Ram bending is the cheapest and easiest method. Tube benders are restrained at two ends and a ram deforms the pipe in the middle. This is suitable for light gauge tubing only. Rotary draw bending is the most commonly used method, and maintains the diameter of the pipe without deformation. In this method, the tube is drawn through a stationary counter-bending die onto a forming die of a specified radius. These tube bending machines are used in the formation of exhaust pipes, process pipes, and any aluminum or stainless steel application where interior deformation can't be tolerated. Bending is similar to rotary draw bending, except that the interior of the tube is supported by a flexible mandrel. The mandrel bends with the tube, ensuring that the interior diameter is not deformed. Ring roll bender is used for bending pipes and tubes with a large diameter. There are three rollers, two on the bottom and one on the top. As the pipe is rolled through, the top roller exerts a downward pressure, bending the pipe. The pressure of the top roller can be adjusted manually or hydraulically, and either two or all three rollers can be powered. This method is used to make drum barrels, awnings, and other circular shapes.

For a tube bending, two things happen to metal. The outside wall is reduced in thickness due to the stretching of the material and the inside wall becomes thicker due to the compressing of the material. The material actually is formed approximately about the centerline of the tube. The material that forms the outside of the bend has further to travel and therefore is stretched; the inside of the bend has less distance to travel and is compressed.

When the ratio of the tube diameter to wall thickness is small enough, the tube can be bent on a relatively small radius. Excessive flattening or wrinkling of the bend should not occur. The outside and inside of the bend tend to pull towards the centerline of the tube. Two factors that help prevent this from happening are a grooved bend die, which supports the tube along the centerline and the natural strength of the tube.

Tube and pipe rollers

2011-09-19T07:54:00.001-07:00

The tube and pipe roller or roll bender machines consists of manual or electronic driven single pinch ring roller machines (noting some have a hydraulic top roll with DRO) and hydraulic driven double pinch models with two hydraulic bottom rolls. The company has a very diverse line of angle roll bender machines to bend tube, pipe, angle iron, solids, squares, and much more.

The manual pipe bender machines consists of two manually driven ring roll benders for bending up to 1-1/4" tubing. These are great tube roller machines for the hobbyist or metal artist. The company also has several ring roller machines that are electronically driven with variable speed inverter drives. These ring roller machines have greater capacities and are easier to operate with two driven bottom rolls. These powered tube roller machines can bend vertically or horizontally for larger section angle bends. All versions in this category have manually adjusted top rolls and are considered single pinch style machines.

The single pinch angle rolls bender line with hydraulic down feed of the top roll has digital positioning readouts for repeatability. The tube benders in this category have three driven rolls for extra power. These roll bender machines are perfect for production fabrication settings where the fabricator is making hay hoops, spiral stair cases, and much more.

Finally the company offers two versions of double pinch angle rolls, hydraulically driven roll benders with hydraulic positioning of the two bottom rolls that are coupled to two separate digital readouts. These angle roll machines have three hydraulically driven rolls. We also have two angle bending machines that have hydraulically driven rolls, hydraulically positioning bottom roll, as well as hydraulically driven lateral guide rolls. These ring roller machines are for bigger section bending projects or for more structural applications. A double pinch bender allows the operator to pre-bend and post-bend the material saving the fabricator time and money. These roll bender machines are easy to use, cost effective, and built for decades of service.

TOLEXPO – 15-18 November 2011

2011-09-12T08:48:00.000-07:00

A partnership with the Midest and Maintenance Expo to create:

· a communication synergy promoting the sector

· a technological showcase bringing together subcontractors' and equipment manufacturers' know-how

The 4^th edition of TOLEXPO, the international show for sheet metal, coil, tube and section

equipment, organized by DBR Event will be held at Paris-Nord Villepinte Exhibition Centre from 15 to

18 November this year. As the economic recovery begins, Tolexpo confirms its position as an

industrial event firmly dedicated to the sector and confirms the success it has achieved, with both

exhibitors and visitors, since its creation in 2005.

6 months before the show opens, Tolexpo already has more than 200 exhibitors, among them both French leaders in the sector and the majority of foreign manufacturers, between them there is also Tauringroup which is a world leader in tube and pipe bending machines.

Almost 11,000 targeted visitors looking for new equipment will discover the products and technical innovations offered by suppliers at the show.

At Tolexpo, visitors will find solutions to all their needs, whether they are looking to renew or modernize their equipment, begin using new technology, improve their productivity, bring their businesses into line with standards and regulations, etc.

For the first time this year, in partnership with the Tolexpo show, Tôlerie magazine is organizing a

competition for students in the various areas which involve sheet metal working.

A Challenge which will bring students together: the Tol&Design Challenge has been created to put the spotlight on the expertise of young people who have chosen the various subjects which involve sheet metal working, and aims to promote these subjects and the production chain itself, by bringing students together to work on an industrial project.

It is also an opportunity for the students to present their expertise to industry professionals by

creating finished products - in this case a chair - using precise specifications.

An initial analysis of the applications shows that students are particularly committed to this project

which is closely connected with the world of work. Teamwork, together with the students' fabulous

motivation, gives them the opportunity to bring their apprenticeships to fruition by carrying a

project through from A to Z.

The organizers of Tolexpo, Midest, the global sub-contracting show and Maintenance Expo, the

maintenance solutions show, are continuing to work together in order to create communication

synergies and boost their industry sectors.

The major objective is to create a technological showcase which will bring the expertise of subcontractors together with that of production equipment manufacturers.

PIPE BENDING MACHINE

2011-08-26T08:02:00.000-07:00

The range of pipe bending machines and accessories represent the best of engineering, manufacture and innovation. For many years there has been very little real choice of stand mounted conduit or copper pipe bender but this new range, featuring some much needed new ease of use features and unique accessories carries on the company tradition of innovation and continual product improvement whilst providing superb value for money. Bending machine is fabricated from 30mm square section tubing to provide a rock solid frame which more than stands up to the rigors of daily use. The frame is designed to give maximum stability, minimizing the risks of sideways movement or skidding across floors, making operation as easy and effective as possible. The formers, which are key to creating a perfect bend, are machined cast aluminum. This means they can provide a superior and highly accurate bend as the machined area provides a perfect profile to support the pipe and gives excellent contact and virtually no movement. By comparison, most other brands use non machined die casts. Included with all machines is a dual purpose stabilizing and extension bar. It can be used to give extra leverage when performing down-bends, or to give extra stability to up-bends by acting as a counter-lever. For electricians, the bar can also be used as a handy cable reel feed by simply securing it through holes in the vice mount, further adding to its versatility. When not in use the bar can be stored securely out of the way on the side of the machine. Another important development on this range of machines is the new design vice mount. Being more substantial than those of other brands, this vice mount offers added functionality. Perhaps most important is the ability of the company mount to accept a wide range of vices, including those of other leading manufacturers, thanks to the universal slots. These slots are also designed to allow the vice to be secured either flush with the edge of the mount or even to overhang, in order to provide clearance to make the threading of conduit much easier, no longer making the vice mount an obstacle to the threading equipment.

Yet another exclusive feature in this range comes in the form of the hexagonal drive featured on the universal and pipe bending machines. Using the optional hexagonal drive key, a power drill can be used to wind the inner shaft of the bending lever handle to quickly and effortlessly move the roller into position.

PIPE BENDER

2011-06-28T03:36:00.000-07:00

Bending machine is fabricated from 30mm square section tubing to provide a rock solid frame which more than stands up to the rigors of daily use. The frame is designed to give maximum stability, minimising the risks of sideways movement or skidding across floors, making operation as easy and effective as possible. The formers, which are key to creating a perfect bend, are machined cast aluminium. This means they can provide a superior and highly accurate bend as the machined area provides a perfect profile to support the pipe and gives excellent contact and virtually no movement. By comparison, most other brands use non machined die casts. Included with all machines is a dual purpose stabilising and extension bar. It can be used to give extra leverage when performing down-bends, or to give extra stability to up-bends by acting as a counter-lever. For electricians, the bar can also be used as a handy cable reel feed by simply securing it through holes in the vice mount, further adding to its versatility. When not in use the bar can be stored securely out of the way on the side of the machine. Another important development on this range of machines is the new design vice mount. Being more substantial than those of other brands, this vice mount offers added functionality. Perhaps most important is the ability to accept a wide range of vices, including those of other leading manufacturers, thanks to the universal slots. These slots are also designed to allow the vice to be secured either flush with the edge of the mount or even to overhang, in order to provide clearance to make the threading of conduit much easier, no longer making the vice mount an obstacle to the threading equipment. Yet another exclusive feature in this range comes in the form of the hexagonal drive featured on the universal and pipe bending machines. A full range of spares and accessories are available. These all have the advantage of being compatible with the equivalent machines of other leading brands.

STEEL BENDING

2011-06-22T09:48:00.000-07:00

Bending is a process by which metal can be deformed by plastically deforming the material and changing its shape. The material is stressed beyond the yield strength but below the ultimate tensile strength. The surface area of the material does not change much. Bending usually refers to deformation about one axis.

Bending is a flexible process by which many different shapes can be produced. Standard die sets are used to produce a wide variety of shapes. The material is placed on the die, and positioned in place with stops and/or gages. It is held in place with hold-downs. The upper part of the press, the ram with the appropriately shaped punch descends and forms the v-shaped bend.

Bending is done using press brakes that normally have a capacity of 20 to 200 tons to accommodate stock from 1m to 4.5m . Larger and smaller presses are used for specialized applications.

Steel bending e metal bending technology delivers both precision and flexibility. The company uses only the latest technology in bending machine. With a fleet of press brakes capable of providing greater design versatility, even higher precision and shorter set-up times, can handle lengths up to 4000mm and apply a force up to 230 tonnes. Extremely large bending spaces, automatic crowning and an intelligent 6-axes backgauge widen our capacity even further!

Since 1908 the company has provided tube bending machines, bending of pipes, bar bending, beam bending, structural steel bending and plate rolling for original equipment manufacturers and construction. That accumulated expertise, along with our state-of-the-art bending machines and highly trained employees, translates into cost effective, 99% error-free quality for all of your steel bending and rolling of other metals.

Our tube bending capabilities include round, rectangular and square tubing from 3/8 inch diameter to 24 inch outside diameter and virtually every size tube in between. Applications include parts for roll-over protection on vehicles, elbows for process plants, and bicycle racks. In construction, tube bending is used for parts of roof trusses, as stringers on bridges, for canopies and circular staircases. The engineers designed and manufactured arms to support the buckets on their front-end loaders.

Products have the capabilities of bending pipes up to 24 inch diameter. Applications include pipe bending for agricultural and construction machinery, for process piping and for antennas. Construction applications include sections for curved pipe trusses, bridges, circular stairs, and canopies. We are bending bars up to 36 inch by 12 inch. Applications include bending bars for flanges to connect pipe, stiffeners around tanks and pipe clamps. Construction applications include bending bars for handrails, strakes on stacks, and curved lintels.

TUBE BENDING

2011-06-08T07:46:00.000-07:00

The most common processes for bending pipe and tube are: ram, roll, rotary-draw, heat-induction, and sand-packing and hot-slab forming. Ram pipe bending was probably the first pipe bending method used to cold-form materials.
This pipe bending method pushes a die against the tube or pipe by a mechanical force, forcing the pipe to conform to the contours of the die. Lacking internal support in the pipe, this pipe bending process creates some cross section ovality. The thinner the wall the more deformation of the pipe is seen.
Maximum pipe bending angle is normally 90 degrees. This is a commonly used pipe bending process where high levels of cross section ovality are acceptable such as furniture tubing, conduit and handrails.
During roll pipe bending, a series of spool-like rollers apply pressure to the pipe as it passes through them. Pipe bending operators change the location of the rollers to produce pipe of the desired radius. This pipe bending process is ideal for forming helical pipe coils for heat transfer applications as well as long sweeping sections such as those used in steel construction-curved trusses and roof components for structures requiring large open spaces. It deforms the pipe cross section very little for such sweeping sections.
The specialization of the company is providing tube manipulation services to clients. There is a range of specialist tube bending and forming services for compressor tubing, square or round tubing and mild steel, stainless steel or aluminium tubing.

The tube bending machines cater for round tubing from 6mm to 60mm with a maximum of 4mm wall thickness and square tubes up to 50mm with a 3mm wall thickness. The machinery works with ferrous and non-ferrous materials particularly mild steel, stainless steel and aluminium.

Square or round tubing can be supplied self coloured or finished, wet or powdercoated painted tubes, or they can be zinc plated for a clear or yellow finish. The company services a wide and diverse range of markets like the pneumatic and compressor markets, automotive, industrial, laboratory, aerospace and retail markets.
The benefit of using square tube bending versus round tubing is that you can attach braces and covering material to it so easily.
Then you can manufacture the rack for the four wheeler or tractor all by yourself to haul that old ice chest that no one makes a carrier that will fit it.
You could manufacture the rack to hold the garbage cans up high enough so that the dogs don't scatter it all over the street. You could make that bracket to hold some of that stuff on the floor of the garage up on the wall. That way you'd have room for more stuff on the floor of the garage.
A neat project would be to make a green house without one weld. It can be done.
The bender can be made without a welder. It can be used to fabricate all kinds of neat things and all without a welder.

ROLL BENDER

2011-06-06T03:59:00.000-07:00

A roll bender is a very robustly built and powerful pipe roller capable. This can be used in any fabrication shop or out in the field on job sites, considering it only requires 220 volts of single phase power to operate. It can be operated in both the vertical mode for small rolling projects, as well as in the horizontal mode for large rolling projects as there are feet on the bottom and back of the machine.

Roll benders work by "pinching" the flat workpiece between two rolls and bending it as it comes in contact with a forming roll. This bends the workpiece into a cylindrical form, where it is welded together to produce a cylinder. Caps are then welded on to produce tanks.
The upper roll is in a fixed position, the lower roll has adjustable movement to perform the gripping function. These are the "pinch" rolls. The third roll (the forming roll) is also adjustable.

Truly built to do the job year after year, these machines are designed with all three rolls driven. This insures easy material feeding and constant pull through of the workpiece.

With a manually or air adjusted drop hinge, the top shaft is automatically raised to release the pressure on the rolled sheet when the tail hinge is lowered. The rear forming roll is adjusted manually on some standard models.

This pipe bending roller has a motor to direct drive gear transmission for positive transfer of power to the drive rollers. The transmission is overload protected by a variable speed inverter drive unit. The variable speed is controlled by a speed pot and becomes very handy when rolling various types and sizes of metal section. This ring roll bender comes standard with foot pedal controls, segment rolls, and lateral roll guides that are very handy when coiling is required. The top roll position is manually descended and the position is indicated on a scale for repeatable bends every time. Optional rolls can be purchased for different profiles like tubing, pipe, angle iron and much more.

Ring rollers are built to a very high quality standard using only the best components on the market. The powered models come with heavy steel plate frame designs, heavy bases, and industrial grade transmissions with overload protection as standard. These ring rollers offer more quality for the investment and will perform decades of service. It is typically in stock for shipments within 72 hours or less.

The technical specifications and standard equipment are:

· Driven Rolls

· Variable Speed

· Rolls are hardened

· Steel bending

· Rolls shafts are a special steel material that is hardened and ground

· Standard Rolls

· Angle Rolls

· Horizontal and Vertical Working Position

· Foot Pedal

· Users manual

CNC BENDER

2011-06-06T03:57:00.000-07:00

The CNC bender can handle a wide variety of tube pipe sizes. This machine has a wide variety of applications, from consumer electronics and various tube/pipework used in ultracompact equipment to the largest machines found in plants, shipping, and nuclear power plants.
CNC Tube Bending adds a new level of speed and precision. The impact of CNC Bending increases as the complexity of the tubular part increases. CNC equipment automatically manipulates the tube in order to precisely position the various bends relative to each other. CNC Tube Bending is usually employed when a part contains more than two bends. Although it is suggested that all of the bends in a part are designed around the same bend radius, the CNC equipment has additional capabilities that allows mixing of bend radii in the same part.
Pipe bender has a wide range of optional software's and functional accessories, having total powers from designing manufacture of hardware/controller to molding dies.
Features in particular:
• Stable accuracy with durability
The mechanism is employed in benders for bending torque transmission, whilst chain-driving mechanism is standard to those of other brands which is doomed to tension looseness as the service is provided.
Mechanism is:
DOB motion stays free from hunting, and longer accuracy performance secured.
Reduced bending head size squeezes out larger bending space for 3D bending of complicated design.
• High machining accuracy
Thanks to the employment of "double-closed " servo driving system controlled by designed sophisticated micro computer LSI, mechanical behavior of positioning is very reliable and stable to maintain accuracy motion regardless of the level of hydraulic temperature, motion speed and backlash. Accuracy-check sequence is also implemented to monitor and apply necessary verification at every bending process all for stable quality bending.
Sturdy steel construction and precise computer controls give CNC bender the ability to create quality bends every time, even when your bending application requires complex or tight-radius bends.

The CNC Tube Benders equipment is capable of manipulating tube and pipe accurately and repeatable from small to large quantity runs.
One of the great benefits being your jobs program is kept on file in the machine so your next order is exactly the same as previously supplied.
It’s a semi- automated system to load and unload tube variants into and from the CNC bending machine.
The tubes are manually loaded into the tube carrier on the transfer chain at the load area. The transfer chain is indexed forward by the indexing cylinder sprocket until the tube is sensed in the unload position.
A pair of pneumatic rotating grippers are used to present the tube to the CNC bending machine. Upon cycle complete a second pair of grippers remove the tube and release it into a collection container.

ANGLE ROLLS

2011-05-25T07:43:00.000-07:00

Angle rolls are made from high-strength chrome-nickel alloy steel, and are the largest diameter shafts of any comparable machine. These heavily proportioned shafts help minimize deflection, resulting in improved bending. The roll shafts are journalled in oversized SKF roller bearings for greatest efficiency and long life. The standard tooling is a combination set for bending machine both leg-out and leg-in, flat bar on flat and on edge, T-bar stem-out and stem-in as well as stem-down, small square bar and even small solid round bar. Normally, no additional spacers are required.
Roll bender machines all come with standard section roll dies on all three shafts. These dies can readily address most square profile applications that an engineer would run into and even round profiles if distortion of the tube or pipe is acceptable. Where no distortion on round tube or pipe applications is acceptable section roller dies for your particular tube and pipe bender size are available. Even though the section roller dies that come standard with the machine can address most square profiles on the market custom section dies are available for square profiles reducing setup time when changing over applications. Custom profiles rolls for extrusions are addressed on a daily basis so forward a sample and a drawing to us so we can offer a feasibility review along with a quote for the custom roll bender rolls.
Standard equipment on all bending machine models are:
• Hydraulically powered rear bending roll adjustment
• Electronic digital readout for rear bending roll position
• Hydraulic drop end
• Hydraulically powered lower pinch roll adjustment, with easily adjustable pinch pressure control with gauge
• Dual rotation controls - console mounted and remote hand control on trailing lead
• Cone bending attachment
• Rolls hardened to 50Rc
• Roller bearings on all roll shafts
• Powered tilting of the rear bending roll for cone rolling
• Simple manual tilt of the lower pinch roll
• Emergency stop cable at front and rear of machine
• Hydraulic oil, tools, and manual

BENDING MACHINES AND ANGLE ROLLS

2011-05-17T07:35:00.000-07:00

Bending machine is versatile, it is easy to operate and is well suited for bending pipe, tube, aluminum extrusions and other sections.

Standard features include double pinch hydraulic forming rolls, hardened precision threaded shafts, and dual adjustable lateral guides.

The design is the result of years of experience and is aimed at providing the highest level of performance, accuracy and consistency throughout the life of the bending machine with the additional advantage of being virtually maintenance free.

The lateral guide rolls are hydraulically powered and can be adjusted to work very closely to the bending rolls, minimizing the distortion of non-symmetrical profiles. Moreover, the guide rolls are equipped with the tooling to bend angle leg-in.

Angle rolls machines are used for bending tube, angle, or shapes into coils, circles or large arcs using a wide variety of materials. By simply adjusting the third roll you change the size of the arc or circle. Tube bending sizes require specific rolls. There are rolls for any application including CNC bender controlled.

Profile rolls often called angle rolls. We used the same technology as our 3 and 4 roll plate bending rolls which results in a stronger and higher quality machine than most other manufacturers but still at a very competitive price.

The rolls can bend almost every profile and section in steel, stainless and aluminum and are virtually maintenance-free.

The components are:

Heavy steel manufactured frame, machined on CNC machining centers for the best accuracy
3 direct driven rolls, with hydraulic planetary motor to eliminate gear boxes, connecting arms synchro devices and clutches
2 forming rolls for reduction of flat ends
double roll spherical bearings SFK or equal = maintenance-free and maximum rigidity
hydraulic motors attached directly to each planetary drive, eliminating the loss of torque
Modular tooling which can be configured to roll most standard sections. Special tooling can be ordered for rolling pipe, tubing or channels the hard way.

Bending a spiral

2011-05-06T06:54:00.000-07:00

Hi, i recently found this nice article about how to make a spiral staircase using a tube bending machine.

For stair handrails it is advised to use a box section, for instance a semi-circular profile.

Start by setting up the machine measuring the radius of your staircase: the machine uses a series of drive rollers that are set out to achieve a degree of pipe bend required.

The pipe is pulled through these angle rolls and then made into an arc.

Useful instructions for copper pipe bending

2010-12-22T07:16:00.000-08:00

Here is another interesting article we found, about how to use a copper pipe bender; there are many commonly used applications which require bending the copper pipe, such as heating, plumbing, air conditioning, etc.

These kind of bending machine allow the user to manually bend pipe to the required angle to connect to the system fixtures.

Copper pipe will straighten slightly after being removed from the copper tube bender. It is advised to bend the pipe about 2 to 5 degrees more than the desired angle. It wikk take some practice to get familiar with this process and correctly judge the extra bend angle to use.

Bending Machines Operator

2010-12-16T09:31:00.000-08:00

A bending machine operator sets up and operates machinery constructed to bend metal structural shapes, such as pipes, tubes, bars, rods, angles, to angle or contour according to speficic requirements such as drawings, templates, or layouts: the operator selects and bolts holding clamp, die block, and guide clamp to machine.
Following, are some of the activities due during the daily operations:

Positioning and clamping end stops on machine to set specified location of bend.

Screwing or insterting or plug stops into guide wheel to set specified degree of bend.

Positioning workpiece against end stop. Locking and holding clamp and guide clamp onto workpiece.

Lubricating workpiece with oil.

Starting turntable to draw workpiece through guide clamp around die block until stopped by plug stops or until dial indicator points to specified degree of bend.
Sliding mandrel into tubing instead of using guide clamp.

Being the bending industry quite big, it can be easy to find several open positions for this kind, despite this industry has been challenged as many others by the struggling faced this year by western countries economies.
For instance, it is whorth looking at sites such as:

Bending Performance Evaluation

2010-12-01T02:24:00.000-08:00

I found this interesting document and I would like to share it with you:
square tube bending performances of aluminum beams reinforced by aluminum plates under three point bending loads have been evaluated using experimental tests combined with theoretical and finite element analyses.
Basic properties of aluminum materials used for initial input data of the finite element simulation were obtained from the true stress-true strain curves of specimens which had bean extracted from the Al tube beams.
True stresses were determined from applied loads and cross-sectional area records of a tensile specimen with a rectangular cross-section by real-time photographing. True strains were obtained from in-situ local elongation measurements of the specimen gage portion by the multi-point scanning laser extensometer. Four kinds of aluminum tube beam specimens adhered by aluminum plates were employed. The bending deformation behaviors up to the maximum load described by the numerical simulation were in good agreement with experimental ones. An aluminum tube beam strengthened by aluminum plate on the upper web showed an excellent bending capability

EuroBLECH 2010: Sheet metal working industry prepares for the uptrend:

2010-10-14T08:08:00.000-07:00

EuroBLECH 2010 shows latest trends and innovative technology From 26-30 October 2010, the 21st International Sheet Metal Working Technology Exhibition
will open its doors again in Hanover, Germany.
This year, the world’s largest trade exhibition for this industry sector will focus upon innovative technologies for the future of sheet metal working.
Enhanced fabrication processes for adapting to changing demand; intelligent
systems and machines for energy-saving and environmentally sustainable production; new materials as well as the latest trends in R&D will be on display.
“The current situation, a period of economic regeneration, demands a great deal of
innovative capacity from every company. After a difficult time, it is important to now set the course for the future by sourcing the right equipment,” explains Nicola Hamann, Exhibition Director EuroBLECH on behalf of the organisers, Mack Brooks Exhibitions. “For industry experts from all over the world, EuroBLECH 2010, with its theme ‘Time for Innovation’, is therefore the first choice when it comes to gaining a comprehensive overview of trends and innovative technology, and to finding suitable machinery and tailor-made solutions”, says Nicola Hamann.

With 1,410 exhibitors from 42 countries and a net exhibition space of 78,000 m2 this year’s EuroBLECH is bigger than the show in 2006, a very successful year for the sheet metal working industry.
“Although this year’s figures do not match the record exhibition in 2008, the
current booking status clearly shows that the sheet metal working industry is on the up again”, says Nicola Hamann.
International participation at this year’s EuroBLECH has risen again slightly, with 46% of exhibitors coming from outside Germany this time. Following Germany and Italy, Turkey now represents the third biggest group of exhibitors. The number of exhibitors from Asia, particularly from China, Taiwan and India, has also increased substantially for this year’s show.
Traditionally EuroBLECH is also a highly international event as regards the visitor numbers. At the last exhibition, 35% of the trade visitors came to Hanover from abroad. A total of 69,400 visitors from 98 countries attended the EuroBLECH 2008 show.

A Guide to Cnc Tube Bending Machines

2010-10-04T05:48:00.000-07:00

Do you know about CNC tube bending machines? These are designed in a fashion to minimize the time of set up and to maximize production. The CNC tube bending machines are available with many companies. Some of the companies have also launched CNC tube bending machines that feature electrical servo-drives on all axes and these are available in single as well as multi stack versions.

CNC pipe bending machines with multistack benders facilitate complicated bending without the requirement of tool change. In case, you cannot apply a multistack tool for stability reasons, try to switch over to an automatic clamp die changing system that will easily accommodate up to eight clamp dies.

The tube CNC bending machines feature excellent bending procedures that are programmable and boosting via the transport carriage in conjunction with the boosting in the area of pressure die. The boosting tends to minimize wall thinning towards the outer bend that further facilitates narrow bending. You can easily achieve a radius of less than 1 x OD. Other important features of CNC tube bending machines include the following:

An MMI multicontrol 2020 system
TFT monitor
Touchscreen
Plausibility verification
XYZ coordinate recalculation into bending parameters
Flexible programming
Multitasking
3-D displays
Integrated modem
Access to the world wide web

The integrated modem and access to the internet works towards providing the best of remote maintenance and technology support.

The CNC tube bending machines has a bending template. This helps in bending the pipe as desired. The unbent portion of the pipe is supported on a pipe that supports rail carries. It is also adjustable in height. The adjustment of height can be easily done by a drive and it is best suited for step-less positioning. This easily sets the pipe-supporting rail to a height that is already specified by the CNC control unit. Before bending the pipe, the height to which the pipe has been moved, is determines via a functioning program that is dependent on a full set comprising of tool data that has been input into the control unit.

Here are the features specifications of a CNC tube bending machines:

Industrial PC control
I/O card machine control
Input of all program to industrial PC via touch screen
Input data of Y.B.C.
Input data according to Descartes X.Y.Z coordination to build bending parameter.
The profile of tube will display on the PC as per the built parameter or input data.
Servo-motor control that feeds axis-X as well as rotates Axis-B, and then bends Axis-C that’s derived via hydraulic pressure
Program transmits via flash disc, floppy disc or the World Wide Web.
Adopt windows XP Embed operation system.
Process of the function auto and manually
Operation via Pedal
Single step change via the operator

Automatic bending rebound numerical compensation data s per accurate measured data.

Steel demand 'to hit fresh highs'

2010-10-04T05:40:00.000-07:00

Global steel demand is expected to hit all-time highs next year, rising above levels last seen before the global economic crisis, a trade body has said.

The World Steel Association predicts world demand will rise 5.3% in 2011 to reach 1.34 billion tonnes, the highest amount since the first half of 2008.

It said continuing steel demand was being led by China, but that Europe was also consuming high volumes of steel.

Yet it added that the end of government stimulus measures may hit steel demand.

The World Steel Association also said that global exchange rate fluctuations could be another factor that clouded its steel output prediction.

For 2010, it says steel demand is likely to rise by 13.1% to 1.27 billion tonnes.

It added that China's demand for steel next year will be 42% higher than in 2007.
