Abstract: A multi-diameter tubular body is cold-forged by forming a large-diameter hole portion in a formed body having a preliminary hole through subjection of the preliminary hole to deep hole forming and by punching out the bottom surface of the large-diameter hole portion to thereby form a small-diameter hole portion. Since a punch having a central protrusion on its forward end surface is used, an internal flaw is generated by dead metal in the inner circumferential surface of a depression, formed by the protrusion, in the bottom surface of the large-diameter hole portion. An outside diameter of a protrusion of a deep hole forming punch is rendered smaller than an inside diameter of the small-diameter hole portion to be formed later by punching out the bottom surface of the large-diameter hole portion. As a result, the internal flaw is removed when the small-diameter hole portion is formed.

Abstract: A ring-shaped core metal is pressed and compressed by a main punch and a counter punch so as to have a wave shape. Moreover, each group of three micro-protrusions provided on each of top points of the wave shape are cut in the core metal. Then, three notches are cut on the core metal corresponding to the micro-protrusions. Furthermore, plastic flow is generated at a surface layer of the core metal due to partial compression by the notches at the time of pressing and compressing. Then, the waves are formed on the core metal with the notches as the top points. The notches are cut at seven sections respectively on a front surface and a rear surface of the core metal. Thus, seven waves are formed on the core metal in total. Since the notches are formed on the front and the rear surfaces of the waves, a “return” phenomenon is not generated as seen in a conventional cool working method. Thus, the waves are formed at high accuracy.
