B, dress workpiece: wheel spoke to be punched is contained on Workpiece clamping seat location, matched moulds；
C, the lock-screw unclamped on described workpiece locating piece have taken out the described wheel spoke of punching hole and get final product.
In above-mentioned technical scheme, more specifically technical scheme is it may also is that described punch is installed on upper bolster by its installing handle, and described angle a is 30 degree, and described angle b is 9.5 degree, a diameter of 13.6 millimeters of described punching post；A diameter of 14.35 millimeters of described crowded Kong Zhu；A diameter of 14.5 millimeters of described concave die cavity.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, owing to having extended downwardly from upper mold limited post in upper installing rack one end, lower installing rack is provided with the lower mold limited post corresponding to upper mold limited post protruded upward；Can the degree of depth in impact extrusion hole be carried out spacing, it is ensured that the size of spoke installing hole epimere conical hole.
2, Kong Zhu top, crowded and the punching post arranged by level from the bottom up due to die section is constituted, it is ensured that punching is squeezed hole and carried out simultaneously；
3, owing to the diameter of punching post is less than the diameter squeezing Kong Zhu；Section bar is made to possess the space of flowing,
4, being arcwall face due to the opening part inwall of die, arcwall face is limited by the circular arc that radius of curvature is 0.2 millimeter～0.5 millimeter；Die can be fitted tightly with workpiece.
5, all it is movably mounted on respective installing rack due to punch mounting seat and Workpiece clamping seat；Easy disassembly, replacing.
