Punch holder is positioned at counterdie, and punch holder two ends are connected respectively the first drift, the second drift with the second bolt by the first bolt.The first drift comprises that first rushes platform and second and rush platform, and first rushes platform is connected to second and rushes on platform.The second drift comprises that the 3rd rushes platform and the 4th and rush platform, and the 3rd rushes platform is connected to the 4th and rushes on platform.
Described osculant piece comprises levorotation piece and right type piece, and levorotation piece is connected with right type piece is symmetrical.
Described levorotation piece inner side is provided with the levorotation plate of protrusion.
Described right type piece inner side is provided with the right template of protrusion.
Described first to rush platform be cylinder.
Described first rushes platform and second, and to rush platform junction be arc transition.
Described second to rush platform be cylinder.
The described the 3rd to rush platform be cylinder.
The described the 4th to rush platform be the frustum of a cone.
The described the 3rd rushes platform and the 4th, and to rush platform junction be arc transition.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Improve product quality; Improve operating efficiency, dimensionally stable; Material consumption is few, has reduced production cost.
