[0030] A support seat 3 is jointly fixedly connected between the inner walls on both sides of the frame 1. The support seat 3 is in contact with the adjacent positioning frame 10. A stamping die lower die 13 is fixedly assembled in the installation groove of the support seat 3. An ejection assembly is installed in the forming cavity of the stamping die lower die 13. The ejection assembly includes an assembly groove, and the assembly groove is opened in the forming cavity of the stamping die lower die 13. A plurality of springs 16 are fixedly connected to the inner bottom of the assembly groove. The tops of the plurality of springs 16 are jointly fixedly connected to a top plate 4. The top plate 4 matches the forming cavity of the stamping die lower die 13. The cooperation of the spring 16 and the top plate 4 has an ejection effect.

[0031] A lifting assembly is fixedly installed on the top of the frame 1. A stamping die upper die 15 is fixedly installed at the movable end of the lifting assembly. The stamping die upper die 15 matches the stamping die lower die 13. The lifting assembly includes a fixed frame 5, and the fixed frame 5 is fixedly installed on the top of the frame 1. An oil cylinder 7 is fixedly installed on the top of the fixed frame 5. The movable end of the oil cylinder 7 penetrates through the fixed frame 5 and is fixedly connected to a mounting plate 14.

[0033] Working principle: During use, the reduction motor 12 drives the belt conveyor 9 connected thereto to operate. The operating belt conveyor 9 drives another belt conveyor 9 to operate through the connecting shaft 17. The two belt conveyors 9 drive the corresponding positioning frames 10 to move through the connecting block 2. When one of the positioning frames 10 moves to directly below the storage rack 8, the workpiece at the bottom falls into the positioning frame 10. As the belt conveyor 9 operates, the workpiece is positioned and conveyed to the lower die 13 of the stamping die. Then the reduction motor 12 stops operating. Then the oil cylinder 7 pushes the mounting plate 14 and the upper die 15 of the stamping die downward. The upper die 15 of the stamping die cooperates with the lower die 13 of the stamping die to complete the stamping of the workpiece. When the upper die 15 of the stamping die resets, the spring 16 and the top plate 4 cooperate to eject the workpiece out of the forming cavity of the lower die 13 of the stamping die. Then the reduction motor 12 operates, and the stamped workpiece is removed and dropped through various components.
