The top and bottom of the reset elastic cylinder 10 are both against a pad 8. There are two pads 8, and the outer surface of the pad 8 is movably sleeved on the outer surface of the screw rod 9. Due to the shape of the mold handle 1 and the positioning auxiliary structure, the positioning effect is achieved with high precision. During the processing, the workpiece can be accurately positioned, avoiding the generation of waste due to position offset, reducing the steps of driving the clamping tooling when using the traditional punching tooling, thereby simplifying the processing flow and improving efficiency. There is greater simplification and optimization in the process, reducing unnecessary operation links, saving time and labor costs, and the downward pressure of the mold handle 1 mainly acts on the parts with low requirements for width and thickness, and can be applied to the parts with low requirements for width and thickness and size, which can ensure that the precision of these parts is guaranteed during the processing, thereby improving the quality and stability of the processing;

[0022] The diameter of the pad 8 is larger than the diameter of the reset elastic tube 10, and the distance between the two pads 8 is less than or equal to the height of the reset elastic tube 10. The reset elastic tube 10 is a rubber tube. When the 16T press drives the mold handle 1 to move upward, the compressed reset elastic tube 10 rebounds to generate an upward force, driving the pad 8, the push rod 7, the unloading plate 4 and the workpiece 2 to move upward at the same time. Finally, the workpiece 2 is reset and can be quickly removed.

[0023] During operation, the workpiece 2 is placed on the sleeve inserted into the punch 3 and fixed in position with the positioning plate 11, and then the 16T press switch is pressed. The 16T press drives the die handle 1 to move downward and acts on the workpiece. The workpiece 2 moves downward, driving the unloading plate 4 to move downward. The ejector 7 is affected by the unloading plate 4 and moves downward through the punch fixing plate 5 fixing baffle. The punch fixing plate 5 presses on the pad 8. The pad 8 squeezes the reset elastic cylinder 10 thereunder. The reset elastic cylinder 10 is compressed by force. Since the workpiece 2 moves downward relative to the punch 3, the punching work is completed. When the 16T press drives the die handle 1 to move upward, the compressed reset elastic cylinder 10 rebounds, generating an upward force, driving the pad 8, the ejector 7, the unloading plate 4 and the workpiece 2 to move upward at the same time. The workpiece 2 is reset, and the workpiece 2 is removed to complete the work. The utility model achieves the positioning effect with the shape of the mold handle 1 and the positioning auxiliary structure, with high precision. During the processing, the workpiece can be accurately positioned, avoiding the generation of waste due to position offset, and reducing the steps required to drive the clamping tooling when using traditional punching tooling, thereby simplifying the processing flow and improving efficiency.
