Hotformed hubs and method

摘要

A method of manufacturing an irregularly shaped forging (10) includes heating a billet (5) to a predetermined temperature, placing the heated billet (5) within the cavity (60) of a die (52), advancing a punch (54) into the cavity to begin to disperse the material into a plurality of radially extending extremities (58) of the cavity (60) and continuing to advance the punch (54) into the die (52) to force a portion of the material to enter predetermined clearance zones (62) between the punch (54) and the die (52) to form an irregularly shaped forging (10) having a plurality of axially extending flash portions (34).
