Each group of guide components is arranged on the base 1, the upper mold base 201 is arranged between each group of guide components, each group of stamping components is arranged on the upper mold base 201, the switching component is arranged on the base 1, and each stamping die 202 is arranged on the switching component.

[0022] In this embodiment: through the cooperation of the stamping components on the upper die base 201 and the stamping die 202, the body sheet metal parts can be stamped, and the guide limit can be achieved through the guide components. The shapes and sizes of the two stamping dies 202 are set according to the actual needs of use and are used to form sheet metal parts. Through the switching components, the two stamping dies 202 can be automatically switched quickly according to production needs to adapt to the production needs of different vehicle models and parts. There is no need for manual disassembly and installation, which greatly improves production efficiency.

[0023] Specifically, the stamping components include a stamping cylinder 205, a mounting plate 206 and a stamping head 207. The stamping cylinder 205 is mounted on the bottom of the outer wall of the upper die base 201 by bolts, the mounting plate 206 is fixedly arranged at the output end of the stamping cylinder 205, and the stamping head 207 is mounted on the mounting plate 206 and the bottom of the outer wall.

[0024] In this embodiment, the mounting plate 206 is driven downward by the stamping cylinder 205 , which can drive the stamping head 207 to stamp the body sheet metal part on the stamping die 202 .

[0025] Specifically, each set of guide components includes a guide column 203 and a guide sleeve 204 . The guide column 203 is fixedly arranged on the top of the outer wall of the base 1 , and the guide sleeve 204 is movably sleeved on the outer wall of the guide column 203 , and the guide sleeve 204 is embedded in the top of the outer wall of the mounting plate 206 .
