Abstract

PURPOSE: To eliminate the degradation in strength such as the occurrence of cracking, etc. near decorative holes occuring in the effect of welding heat by performing piercing of the decorative holes of a disc for metal wheels after assembling and welding the disc to a rim.
CONSTITUTION: After a disc of metal wheels is assembled and welded to a rim 8, it is placed and set on a die which matches the concave and convex parts of the disc face thereof and decorative holes are blanked by pressing from its top face. Then, the remaining of thermal stress in the portion closed to the weld zone 12 in particular owing to eneven transfer and rediation of surplus heat along the decorative hole face 3 in the case of welding after blanking of the decorative holes 6 is eliminated. Also, coarsening of the metal structure of the strong plastic working portions of the decorative hole blanked edge parts is obviated. Hence, strength is improved without increasing the plate thickness of the disc material and the lightweight and strong wheel is obtained.
