Description of Copper Tube Straightening Flaring & Bending Machine

This copper tube straightening flaring & bending machine is specially designed for decoiling, straightening, end forming, bending, and cutting coil copper tubes into different shapes, used in air conditioners and heat exchangers.

This machine is an integrated machine, combing straightening, end forming and 3D bending together. There is robot manipulator automatically move end-formed parts to bending station.

The machine is PLC control, HMI operation, full automatic, high uniformity, no labor required.

This machine line is designed to be heavy-duty for max. copper tube OD 22mm. The clamping force for bending will be hydraulic and servo motor for bending will be much bigger.
