The hydraulic rod of the hydraulic cylinder 3 extends and drives the top seat 4 and the die 5 to move downward. As the die 5 gradually descends, the pressure plate 10 will come into contact with the material. With the help of the moving rod 1102 and the support spring 1103, the material is pressed and fixed on the placement table 20 to prevent the material from shifting during punching. At this time, the die 5 can punch the material. After punching is completed, the hydraulic rod of the hydraulic cylinder 3 retracts and drives the top seat 4 and the die 5 to return to their original position. The punched material can then be removed.

[0033] When it is necessary to disassemble and replace the die 5, turn the knob 13 forward to move the screw 7 upward, which will drive the support plate 8 and the insert block 9 to rise until the insert block 9 is completely separated from the die 5. Then, hold the handle 17 of the die 5 and slide the die 5 out of the top seat 4 through the slide plate 16 to complete the disassembly of the old die 5. According to the new punching requirements, select the appropriate die 5 and repeat the steps of the die 5 installation stage to install the new die 5 into the top seat 4.

[0034] Finally, regularly inspect the equipment and tighten or repair it. Specifically: check sliding parts such as slide plate 16, guide block 12, and guide groove, add lubricating oil regularly to reduce friction, ensure smooth sliding of parts, and extend the service life of the equipment; check spring 1103, and replace it in time if spring 1103 is found to be deformed, less elastic, or broken, to ensure that pressure plate 10 can properly perform its function of pressing materials; check the power cord of hydraulic cylinder 3 and repair or replace it in time.
