Stating low punch includes the pedestal in " convex " type mesa-shaped and the core bar on pedestal, and the center of the pedestal, which is equipped with, penetrates the pedestal
Through hole, the core bar be arranged on through hole in；The length of the core bar is more than the length of through hole, and core bar is higher than the head of through hole
It is divided into the head of low punch.
Preferably, the upper punch includes upper punch head and upper punch shank, and the upper punch shank is arranged on upper punch
The top center on head, and upper punch shank is perpendicular to upper punch head；The top of the punching press cavity is equipped with to punching press cavity
The annular limiting section of axle center protrusion, the upper punch head are arranged below limiting section, the outer diameter on the upper punch head and punching press
The internal diameter matching of cavity, the outer diameter of the upper punch shank are matched with the internal diameter of limiting section.
Preferably, the top outer diameter of the pedestal is matched with the internal diameter of punching press cavity, and the head outer diameter of the core bar is less than
The internal diameter of punching press cavity.
Preferably, it is slidably and sealingly connected between the core bar and through hole.
The beneficial effects of the utility model are：The structure of low punch is improved, is the bottom of low punch when pushing
The top of seat pressurizes to green compact for second, and core bar sinks not to product for the second time with raw relative motion is adopted between the pedestal of low punch
Pressurization ensures green compact consistent in density up and down.
