Abstract

PURPOSE:To simplify the process and to reduce the cost by forming a hole to which one end of a shaft base material is fitted, on a body base material, combining both of them, executing back extrusion by a forming mold, and executing simultaneously the formation of the body and a coupling of the body and the shaft. CONSTITUTION:A cup-shaped body base material 10 and a shaft base material 11 are prepared separately, and these base materials 10, 11 are brought to annealing and lubricating treatment. Subsequently, the body base material 10 is brought to forge working by a press machine, and a hole 10a to which one end of the shaft base material 11 can be fitted is formed in the center of the end face of the body base material 10. One end of the shaft base material 11 is fitted into this hole 10a, and it is inserted and attached in a forming metallic mold of the press machine. Subsequently, the body material 10 is deformed plastically by back extrusion by the press machine, a cup-shaped body part 12 is formed, and simultaneously, at the time of this back extrusion working, a fitting tip part 111 of the shaft base material 11 is expanded and elongated in the peripheral direction. In this way, the body part 12 and a shaft part 13 are coupled as one body. Subsequently, its finish forming is executed in order to raise the accuracy of an inside diameter part 12C of the body part 12.
