Product Description

I Description of automatic copper tube straightening end forming and bending machine

This 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 integrated, combing straightening, cutting, flaring and bending together. There is robot manipulator automatically move flared parts to bending station.
The machine is PLC control, HMI operation, full automatic, high uniformity, no labor required.
This machine is of high efficiency, one bend only takes 3~ 4 seconds.
