This bending machine is specially designed for electric cooker rolls. The bending die is driven to revolve by the speed control mechanism. 

After both ends of the roll are bent by other machines, put one end into the positioning mechanism in punching die. Press the button, and the pneumatic mechanism pushes the forming compacting wheel to coil the roll. When it touches the inductive switch, it turns back and the compacting wheel mechanism is turned on. 

This tube bending machine produces accurate sizes with low labor intensity and high efficiency. It produces more than 400 pieces per hour. If you change the mould, you can bend other round components in the same way.
