Title: Cold ironing method for forged parts
Inventor: KOIDE YOJI
IPC: B21J5/12
Filed: 1986-10-29
Abstract: PURPOSE:To prevent fouling from being generated on the inside surface of a hole, and to simplify the process by bringing only the inside surface of a U-shaped groove hold to cold ironing at the time of cold ironing of the hole inside surface of a through-hole having a U-shaped groove hole in the outside periphery of a roughly circular center hole. CONSTITUTION:An ironing die 26 is a columnar die which can be fitted loosely into a through-hole consisting of a roller groove 14 which is connected to a center hole 12 of uniform joint parts 10 and its outside periphery and provided in a position for dividing equally the outside periphery. This ironing die 26 is constituted so that only a hold inside surface 18 of the roller groove 14 can be ironed, and at the time of ironing working, the ironing die 26 is not brought into contact with a hole inside surface 16 of the center hole 12. Accordingly, at the time of ironing, a metal extruded from the hole inside surface 18 of the roller groove 14 can escape toward the center hole 12, therefore, no fouling is generated, and also, a life of the ironing die 26 is extended. Moreover, the subsequent drill working of the roller groove, or as the case may be, rough broaching working can be omitted.
