The head part and the bed piece of the pipe bending machineadopt reinforcing design. The internal stress can be eliminated byannealing. The strength and rigidity of the pipe bending machine isguaranteed; Prevent it from permanent distortion.

Advanced and safe arc descending structure is adopted. Two downrollers go up and down in an arc around the up roller; Thedisplacement is displayed clearly.

Three driving rollers, drived by three independent hydraulicmotors. There are two hydraulic rollers on both sides of the pipebending machine, which prevent the asymmetrical section bars frombeing distorted.

Hydraulic driving structure can fulfil pre-bending and bending at atime.
