[0024] Specifically, the workpiece to be processed is placed on the upper surface of the mounting base 1, and the mounting base 6 is driven to move downward by starting the hydraulic cylinder 17. When the fixing ring 11 contacts the workpiece to be processed, under the action of the third spring 12, the workpiece to be processed can be fixed to the upper surface of the mounting base 1 through the fixing ring 11 while the mounting base 6 descends, and the mounting base 6 continues to move downward. Under the action of the first spring 4, the mounting base 6 can push the first mounting ring 5 to move downward while cutting the workpiece to be processed. The mounting base 6 continues to move downward. When the second mounting ring 10 contacts the hole-turning punch 3, under the action of the second spring 9, the workpiece to be processed can be fixed on the upper surface of the hole-turning punch 3 while the mounting base 6 descends. When the mounting base 6 continues to descend to turn the hole and the punching head 8 contacts the workpiece to be processed, it continues to move downward to punch the workpiece to be processed. After punching, the force at the center of the workpiece to be processed is reduced, and the workpiece to be processed after punching is stretched downward by the lower surface of the mounting base 6 and the squeezing force of the first mounting ring 5 on the workpiece to be processed to achieve hole turning.

[0025] Reference Figure 2A material discharge groove 13 is opened inside the hole-turning punch 3, and a guide plate 15 is installed inside the hole-turning punch 3 and the mounting base 1. A certain space is left above the guide plate 15. One end of the guide plate 15 is inside the material discharge groove 13, and an additional ring 14 is fixedly connected above the inner wall of the hole-turning punch 3.

[0026] Specifically, the remaining material after punching falls from the discharge chute 13 into the guide plate 15 , and the remaining material can be discharged from the guide plate 15 , effectively preventing the remaining material from affecting the next hole-turning operation.

[0027] Reference Figure 2 The second mounting ring 10 and the fixing ring 11 are both made of rubber.

[0028] Specifically, since the second installation ring 10 and the fixing ring 11 are both made of rubber material, the workpiece to be processed is effectively fixed, the processing quality of the hole punching is improved, and the workpiece to be processed is prevented from being damaged.

[0029] Working principle: The workpiece to be processed is placed on the upper surface of the mounting base 1, and the mounting base 6 is driven to move downward by starting the hydraulic cylinder 17. When the fixing ring 11 contacts the workpiece to be processed, under the action of the third spring 12, the workpiece to be processed can be fixed to the upper surface of the mounting base 1 through the fixing ring 11 while the mounting base 6 descends. The mounting base 6 continues to move downward. Under the action of the first spring 4, the mounting base 6 can push the first mounting ring 5 to move downward and can cut the workpiece to be processed. The mounting base 6 continues to move downward. When the second mounting ring 10 contacts the punch 3, the second spring 4 pushes the first mounting ring 5 to move downward. Under the action of the spring 9, the workpiece to be processed can be fixed on the upper surface of the punching punch 3 while the mounting seat 6 descends. When the mounting seat 6 continues to descend to perform punching and the punching head 8 contacts the workpiece to be processed, it continues to move downward to punch the workpiece to be processed. After the punching is completed, the force at the center of the workpiece to be processed is reduced, and the workpiece to be processed after punching is stretched downward by the lower surface of the mounting seat 6 and the squeezing force of the first mounting ring 5 on the workpiece to be processed to achieve punching. The workpiece moves upward through the hydraulic cylinder 17. Under the action of the first spring 4 and the second spring 9, the workpiece formed by the punching can be effectively prevented from sticking and demolding can be achieved.
