After the steel bar is bent, the power drive mechanism drives the stepping mechanism to drive the whole bending mechanism to move on the track to another position where the steel bar needs to be bent to bend the steel bar. Several places need to be bent on the steel bar, and the power drive mechanism drives the stepping mechanism to drive the whole bending mechanism to move and stop several times. When bending another steel bar, the stepping mechanism drives the bending mechanism to move back to the initial position again, repeating the above actions.
