Tube bender designed for small-batch production

Innovative Tube Equipment Corp. offers the Unison EvBend 2000 rotary draw tube bender for producing precision tubular parts in small volumes. Target sectors for the new machine, which can bend tube diameters of up to 2 in., include shipbuilding and oil and gas.

The machine combines manual setup with semimanual operation of the bending arm, which has servomotor power assistance. With this approach, an operator can use the machine with just a few minutes of training. The CNC system that controls the tube feed, carriage rotation, and bend axes helps ensure precise bending results, the company states.

Users can create bends by entering the standard tube bending information into dialog screens on the Windows® operator interface or transferring data from a CMM. Users also can program the machine using a teaching mode, which allows a part to be reverse-engineered by bending and comparing a tube against an existing part, with the user capturing the underlying material feed, rotation, and angle of bend information as the desired points are reached.

The machine can provide a bend torque of up to 4,056 ft.-lbs. to assist operation of the bend arm. This assistance allows machines to handle tubing made from hard, high-performance alloy materials. The ultracompact bending head permits bending of complex, multibend parts.
