Requirements in tube bending

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.

Tube and pipe rollers

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.

PIPE BENDING MACHINE

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.

CNC BENDER

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

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
