A mounting plate 22 is fixedly connected to the top of the slider of the first electric linear slide 21. A second electric linear slide 23 fixedly connected to the bottom of the support plate 3 is fixedly connected to the top of the mounting plate 22.

[0029] In this embodiment, during actual use, the two electric linear slides can drive the stamping template to move forward and backward or left and right respectively, so as to move below the punching head 10.

[0030] Among them, sliding rods 12 are fixedly connected to the top of the base 1 and the top of the mounting plate 22, and sliding sleeves 13 that are respectively slidably connected to the two sliding rods 12 are fixedly connected to the bottom of the mounting plate 22 and the bottom of the support plate 3.

[0031] In this embodiment, during actual use, when the mounting plate 22 and the support plate 3 move, the sliding sleeves 13 will also slide on the outside of the sliding rods 12, providing support for the receiving frame 4 together with the two electric linear slides.

[0032] Among them, the inner top surface of the stamping template 5 is concave, and a switch door panel is provided inside the receiving frame 4.

[0033] In this embodiment, during actual use, the concave stamping template 5 adapts to the size of the metal plate to limit the metal plate.

[0038] Working principle:

[0039] First, place the metal plate to be stamped into the stamping template 5. Start the hydraulic push rod 7 to lower the punching head 10 to stamp the metal plate. At the same time, the operation of two electric linear slides can be controlled to change the stamping position. When it is necessary to change the hole pitch of stamping, the connecting sleeve 9 can be separated from the fixed block 8 by screwing the bolt 111 and the nut 114. The surface of the fixed block 8 can be marked with a scale, so that the distance between each punching head 10 can be adjusted. At this time, the stamping template 5 can also be replaced accordingly to ensure compatibility with the punching head 10. The metal chips generated after stamping will fall into the receiving frame 4 through the punching holes of the stamping template 5. After the chips in the receiving frame 4 reach a certain amount, the switch door panel can be opened for cleaning.
