[0025] Embodiment 3

[0026] Based on the first embodiment, four equally spaced guide rods 14 are fixedly provided on the top outer wall of the base 1, and a return spring 15 is sleeved on the outer wall of the guide rod 14. Four equally spaced guide holes 16 are opened on the outer wall of the positioning plate 3. The inner wall of the guide hole 16 and the outer wall of the guide rod 14 are slidably connected to facilitate guiding the positioning plate 3 to rise and fall on the top of the base 1. A docking block 17 is fixedly provided at the top center position of the positioning plate 3, and the docking block 17 is used to facilitate the connection of the utility model with the output end of the punching machine.

[0027] Working principle of this utility model:

[0028] Refer to the instruction manual Figure 1-3When the utility model is used, firstly, the docking block 17 provided on the top of the positioning plate 3 is connected to the stamping end of the stamping equipment, and then the rectangular steel plate is placed on the top of the lower die cavity 2, and the four corners of the rectangular steel plate are aligned with the inner walls of the four right-angle positioning plates 8, so as to facilitate the positioning of the steel plate. At this time, the four corners of the rectangular steel plate are supported on the top of the first right-angle guillotine 6, and the output shafts of the four synchronous hydraulic push rods 11 are lowered, driving the lower pressing block 12 and the second right-angle guillotine 13 to descend. The four second right-angle guillotine 13 are squeezed on the four corners of the steel plate, and the four first right-angle guillotine 6 can be used. The four corners of the steel plate are cut off to facilitate stamping of the steel plate. There is no need to cut off the four corners of the steel plate in advance and then place it on the stamping die for stamping, which reduces the processing steps of the battery shell, reduces the production cost of the battery shell, and improves the production efficiency of the battery shell. After the four corners of the rectangular steel plate are cut, the output shafts of the four synchronous hydraulic push rods 11 shrink. At this time, the positioning plate 3 is driven down by the output end of the stamping equipment, and is pressed into the inner cavity of the lower die cavity 2 through the lower module 4 to stamp the steel plate. After the steel plate is stamped, it is reset through the output end of the stamping equipment to take out the stamped metal shell.
