The bending die 4 is rotatably connected to the rotating shaft. The dynamic shearing clamp 5 is pushed to rotate around the rotating shaft by the output end of the hydraulic cylinder 7 to provide a bending shear torque for bending operations.
[0027] Furthermore, the bending die 4 is a disc-shaped structure with a notch, the body of the movable shear 5 is flush with the vertical end face of the notch on one side of the bending die 4, and the body of the movable shear 5 is fixedly connected to the end face of the bending die 4 by bolts, and is used to drive the bending die 4 to rotate synchronously through the movable shear 5.
