TUBE BENDING

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

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.

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
