Patent ID: 7523555

Claim:
A wheel manufacturing method comprising: a pressing step in which a primary molded product having a cylindrical shape with a bottom in which a flange part that extends to the outside in a direction substantially perpendicular to the center line is disposed on the open side end part is manufactured by press-molding a rolled metal plate; a working step in which a secondary molded product is obtained by cutting away the bottom part of said primary molded product; and a spinning step in which, while the flange part is allowed to deform in the direction of the thickness thereof, the secondary worked product is fit over and fastened to a rotating jig having a receiving surface that receives the flange part from the inside, a rim flange molding roller is pressed against the end part of the flange part in the direction of extension of the flange part while the secondary worked product is rotated together with the rotating jig, so that the flange part is gradually molded into the shape of a rim flange part, and the flange part is subsequently subjected to an angular adjustment to an appropriate angle to mold a rim flange part.
