Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to
Following embodiments.
Embodiment 1:
A kind of punching tool mechanical safety mechanism, shown in Figure 4, punching tool includes punching platform 1, Yi Jishe
Lower mold holder 6, guide post 5 and top mold holder 2 on punching platform 1 are set, is respectively arranged in punching in top mold holder 2 and lower mold holder 6
Mould 3 and punching lower die 7, mechanical safety mechanism include that the support rod 14 being vertically mounted on punching platform 1, level are slidably installed
In the baffle 13 in top mold holder 2 and it is fixedly mounted on the lock cam 11 that in top mold holder 2 and can be rotated in a vertical plane,
The locking through-hole passed through for support rod 14 is equipped in top mold holder 2 in the stroke of 13 one end of baffle, top mold holder 2 is another in baffle 13
