During the upward return stroke of the stamping assembly 8, a spring 19 is used. The stretching and rebounding effect of, drives the stamping assembly 8 to move upwards. The stamping cylinder 6 does not need to provide power, and only provides upward pulling force through the rebounding action of the spring 19 to form a stamping cycle. The entire stamping process is safe, stable, automatic and efficient.
[0029] The mounting base 1 is provided with an intermittent rotating mechanism. The intermittent rotating mechanism includes an intermittent drive mechanism 21 and a rotating mechanism 22. The rotating mechanism 22 is rotatably connected to the intermittent drive mechanism 21. The rotating mechanism 22 includes a chassis 23, a rotating link 24, a ratchet 25 and a rotating mechanism.
