[0017] Specifically, a mounting groove 12 is opened inside the processing platform 1, and the mounting groove 12 is located at the lower side of the mold cavity 11.

The top of the connecting rod 87 passes through the processing platform 1 and is fixed to the lower end face of the push plate 86. The push plate 86 is made of magnetic metal material.

[0019] By adopting the above technical solution, when working, the user first places the disc-shaped metal material on the mold cavity 11, and then the user controls the controller connected to the hydraulic cylinder 2 13 and the motor 89 to operate, first controlling the hydraulic cylinder 2 13 to push the mounting plate 14 upward in the mounting groove 12 to move, and then push the motor 89 and the push plate 86, the connecting rod 87, the sleeve 88, etc. to move upward together, until the push plate 86 moves to the center hole groove of the driving disk 83, and the two are matched. At this time, the user controls the electromagnet 1 85 on the inner wall of the hole groove to conduct electricity and the electromagnet 2 is powered off. At this time, the driving disk 83 magnetically attracts the push plate 86 through the electromagnet 1 85, and then controls the motor 89 in real time to drive the push plate 86 to rotate, and further drives the driving disk 83 to rotate inside the rotating groove 15 through the electromagnet 1 85. At this time, the clamping plate 82 located on the processing platform 1 is under the action of the sliding bar 821 and the displacement groove 84 on the driving disk 83 at the bottom of the sliding bar 821, so that the sliding bar 821 moves inside the sliding groove 81.

After the correction and clamping are fixed, the electromagnet 1 85 is powered off, the electromagnet 2 831 is conductive, and the push plate 86 moves downward under the action of the hydraulic cylinder 2 13. The downward movement range can be adjusted according to the stamping depth data of the workpiece to be processed. Then the user controls the hydraulic cylinder 15 to push the die base plate 3 downward under the guidance of the guide column 2, and the punch head 7 under the die base plate 3 cooperates with the die cavity 11 to stamp and forge the workpiece. The connection rod 87 and the sleeve 88 are connected by screws to facilitate the user to replace and maintain, and even adjust the height of the push plate 86.
