Bending, end forming and swaging

7-axis all-electric tube bender LANGBOW Ltd is the sole UK supplier of SOCO machinery, including the SB- 32x7A-2S-V-U.

It may also be optionally provided with automatic loaders and automatic unloaders for full automation. The company states that the tube bender can offer one of highest performance solutions available. The machine features bending, rotation, feeding, machine head seat horizontal moving, machine head rotation, clamping die, and pressure die clamping, along with left and right bending capabilities in the same cycle. Other features include easy programming, automatic mandrel lubrication, touch screen with industrial PC, and multi-stacks/multi-radius.

The new SOCO CNC tube bender combines draw, roll and dual direction bending way technology. The line is suitable for complex parts and shapes, such as automotive exhaust pipes, and health care and fitness equipment. It is equipped with seven electric CNC axes and 2+2 bending stacks, and uses SOCO’s DGT technology (direct gear transmission) for high speed and accuracy.

This CNC tube machine features an all-electric tube bender (seven electric servo control axes), which is equipped with left and right bending technology for maximum flexibility and minimal interference, with capacity up to 32mm OD.

Induction spool bending machines

the pipe in between the bends is also significantly faster thanks to the ability to rotate the pipe 180° in one go.” Pipes are automatically loaded and positioned into the machine by a pipe feeder, eliminating the use of cranes during loading and reducing the load time to less than two minutes. “Because of market demand Cojafex is currently engineering a PB600FBR for pipes up to 24" and a PB100R machine for pipes up to 4" along these same lines,” said Mr Alders. “This is a welcome addition to our standard line of machines, which goes up to 64".” Induction bending is a method of producing pipe bends in a wide range of materials. It is claimed that induction bends can be produced more accurately than their cold bent counterparts and with better wall thinning and ovality. A free choice of radius and angle takes away the design limitations of spools made with fittings, and this can be done without investing in costly additional tooling.

automatically create spool pieces with bends of 1.5 DN and greater. Spools can be made out of standard pipe, eliminating the need for elbow fittings. This reduces the cost of bevelling, welding and inspection. “The PB450R has been designed to outdo its predecessors on performance,” commented Mr Alders, technical director of Cojafex. “It can process 50 per cent stronger pipe and it has 55 per cent more induction power. Manipulation of

COJAFEX has introduced a new line of smaller-sized spool bending machines for diameters ranging from 2" to 24". The PB450R for pipes up to 18" is the larger brother of the PB Special model. “We are very happy with the PB Special, which we have had for 15 years, and the addition of this machine allows us to serve a significantly larger market,” said Tormod Lie, CEO of NIRAS, after installation of the first PB450R. The machines are designed to
