Abstract
Described herein is a method for shaping aluminum wheels, which comprises the steps of: (A) supporting opposite rim portions of a cylindrical forging aluminum work substantially of H-shape in section by means of spinning dies, and subjecting the work to primary spinning including press-shaping by a work-stretching first spinning roller and preliminary spinning by a second spinning roller; (B) flaring the inner end of the rim; (C) annealing the work to remove the work-hardening resulting from the flaring operation; and (D) subjecting the work to secondary spinning including final spinning by the second spinning roller and corner R-finishing by a third spinning roller.
