Abstract

PURPOSE: To provide teh subject method which comprises the steps of forming a through hole at the central part of semiprocessed product symmetric relative to a shaft obtained by free forging, and shaping an asymmetric part relative to the shaft by mold foreging, thereby to manufacture a saddle type pipe base while preventing as less as possible the generation of local stress in the forging step.
