[0032] The support and limiting component 3 is used to support and limit the left and right sides of the steel plate. The lifting end of the stamping component 2 can drive the pushing component 5 to move downward so that the pushing component 5 and the positioning component 4 can complete the positioning of the front and rear sides of the steel plate.

[0033] When stamping the steel plate, the steel plate is moved into the interior of the two support limiting components 3, and then the lifting end of the stamping component 2 is driven so that the lifting end of the stamping component 2 can drive the pushing component 5 to move downward, and the pushing component 5 can push the steel plate backward, so that the pushing component 5 and the positioning component 4 position the front and rear sides of the steel plate. Then the stamping component 2 begins to stamp the steel plate.

[0034] By placing the steel plate inside the two support limiting assemblies 3, the support limiting assemblies 3 can support and limit the two sides of the steel plate at the same time, then the lifting end of the stamping assembly 2 is moved downward, so that the pushing assembly 5 can push the steel plate and complete the positioning of the front and back sides of the steel plate with the positioning assembly 4. Since the four sides of the steel plate are limited, the steel plate will not displace when the stamping assembly 2 is working, so that the overall shape and size accuracy of the steel plate after processing can be guaranteed, and the situation that the two blade edges of the stamping assembly 2 directly collide and cause the blade edge to collapse or wear out is avoided.

[0035] In one embodiment, for the above-mentioned stamping assembly 2, the stamping assembly 2 comprises a lower die 201, the lower die 201 is fixedly installed on the top of the workbench 1, the top of the workbench 1 is fixedly installed with a mounting frame 202, the top of the mounting frame 202 is fixedly installed with a hydraulic cylinder 203, the output end of the hydraulic cylinder 203 penetrates through the mounting frame 202 and is fixedly installed with an upper die 204, the bottom of the mounting frame 202 is provided with a mounting groove 205 corresponding to the lower die 201, and the inner wall of the mounting frame 202 is fixedly installed with a reinforcing rib 206.

[0036] The steel plate is placed on the top of the lower die 201, and then the hydraulic cylinder 203 is driven, so that the upper die 204 is driven downward by the hydraulic cylinder 203, so that the upper die 204 cooperates with the lower die 201 to complete the punching and blanking of the steel plate. The material ejecting device can be arranged at the bottom of the workbench 1, the material ejecting device can lift the punched steel plate in the lower die 201 through the mounting groove 205, so that the steel plate can move out of the lower die 201, and a collecting device can be arranged at the bottom of the mounting groove 205, so that the debris and waste generated during punching of the steel plate can directly fall into the collecting device through the mounting groove 205. The reinforcing rib 206 can support the mounting frame 202, so that the stability of the mounting frame 202 when supporting the hydraulic cylinder 203 and the upper die 204 can be guaranteed.

When the L-shaped positioning plate 402 moves, the T-shaped guide rod 403 can slide on the mounting frame 202. This arrangement ensures the stability of the first adjusting screw 401 when pushing the L-shaped positioning plate 402. When the steel plate on the L-shaped supporting plate 303 is pushed, the steel plate can move to the inside of the L-shaped positioning plate 402, so that the L-shaped positioning plate 402 can position the back side of the steel plate.

The arrangement of the inclined pushing block 503 installed on the upper die 204 makes it not hindered when the steel plate is placed inside the two L-shaped support plates 303. Meanwhile, the arrangement of the inclined surface on the inner side of the inclined pushing block 503 makes the upper die 204 move downward, if the rear side of the steel plate is not in sufficient contact with the inner wall of the L-shaped positioning plate 402, as the inclined pushing block 503 continuously moves downward, the inclined surface of the inclined pushing block 503 can push the front side of the steel plate, so that the steel plate can be in sufficient contact with the inner wall of the L-shaped support plate 303, and the inclined pushing block 503 cooperates with the L-shaped support plate 303 to complete the positioning of the front and rear sides of the steel plate.
