Method of manufacturing outer ring member for constant velocity joint
摘要:
A method of manufacturing an outer ring member for a constant velocity joint, comprising the steps of forming a secondary molding by applying a preliminary upsetting to a work after applying a forward extrusion-molding to the work, forming intermediate pre-molded bodies having annular sloped surfaces formed thereon to have a difference in flow resistance between large diameter parts and small diameter parts by applying the upsetting to the upper part of the secondary molding, forming a quaternary molding having a cup part with track grooves by applying a backward extrusion-molding to the intermediate pre-molded bodies, and applying an ironing to the cup part of the quaternary molding to finish the quaternary molding to product dimensions.
