Abstract
PURPOSE: To forge toothed wheels with projection by excellent yield rate by forming the projection part to the material by pressing with dies, the shaft part in the punching hole part of the upper and lower dies, and not only by molding the toothed whell part by pressing the shaft part with the upper and lower punches but also making it the final shape.
CONSTITUTION: The round bar material is put into the cavity which is formed by upper die 1, upper punch 3, sleeve die 5, lower die 2 and lower punch 4, and by pressing it with the upper die 1 and giving plastic deformation to the material, the projection part 12 is formed. At the same time, the material is filled in the part through which the upper and lower punches 13, 14 of the upper and lower dies 1,2 are made to penetrate, and the preform 15 equipped with the necessary projection part 12 and the shaft parts 13, 14 is molded. Subsequently, by pushing in the upper and lower punches 3, 4 by the regular amount in the direction which compresses the shaft parts 13, 14 and pushing out the disk part 16 of the preform 15 in the circumferential direction, the toothed shape part 17 is formed, and the finished product 18 of desired toothed wheels with projection can be obtained.
