[0002] Pipe benders can be roughly divided into numerical control pipe benders, hydraulic pipe benders, etc. For the pipe bending operation of a numerical control pipe bender, a suitable die head is selected according to the outer diameter of the pipe to be bent and sleeved on the oil cylinder plunger. The oil cylinder drives the die head to move towards the position corresponding to the groove of the roller shaft to clamp the steel pipe. After the steel pipe is clamped, according to the bending angle, the oil cylinder is driven by the motor to rotate around the roller shaft to realize the pipe bending operation of the metal steel pipe.
