The above scheme solves the problem that the electromagnet is used to forcibly suck the stamped parts out of the mold, and the lack of a buffer device easily causes the parts to be damaged by friction with the mold.

[0023] According to the present specific embodiment, the L-shaped plate 102 is fixedly connected to the stamping table 101 and is located above the stamping table 101. The buffer assembly includes a stamping part, a push plate 105, a push-out part and a knocking part.

When the stamping operation is performed, the parts press down the pushing plate 105, the spring 110 and the telescopic rod 109 are compressed, and the bottom plate 111 fixes the telescopic rod 109. When the stamping operation is completed, the upper mold 103 is reset, and the parts are pushed out by the retraction of the spring 110 to prevent the parts from being damaged by friction with the mold when they are forcibly adsorbed.

[0026] At the same time, the knocking rod 112 is fixedly connected to the base plate 111 and is located below the base plate 111. The driving motor 113 is fixedly connected to the stamping table 101 and is located inside the stamping table 101.

[0028] A stamping device according to the present embodiment is used, by setting an L-shaped plate 102, a buffer assembly, an upper die 103 and a lower die 104.
