摘要： A preformed product of a crankshaft is formed in a shape smaller than a shape of a cavity of a separatable die set 1103 composed of an upper die and a lower die and is disposed in the cavity of the die set 1103 as a material M. The cavity of the die set 1103 matches a required shape of the crankshaft. When the material M is disposed in the cavity of the die set 1103, a clearance is formed between the material M and the cavity, and when a side-forming punch 1000P is inserted into the material M, a hollow hole is formed in the material M and the cavity is filled with the material M. As a result, not only can weight saving be achieved by forming the hole in the crankpin of the crankshaft, but also degradation of dimensional accuracy by forming the hole can be avoided.

摘要： There is provided a method by which a member having an undercut in the inner peripheral portion thereof can be formed readily. To form a material (1) formed with a recess (2) and the undercut (3) by using a swaging device, while the material (1) is first gripped by a damper (11), and a mandrel (12) is inserted into the recess (2) of the material (1). The mandrel (12) used has an outside diameter equal to the inside diameter of a blind hole of an aimed product (fuel injection nozzle). Then, the material (1) is pushed in by the mandrel (12) to a position at which the material (1) abuts on a stopper (13), and the outside surface of the material (1) is struck by swaging dies (8) to perform a swaging operation. This swaging operation reduces the inside diameter of the recess (2) to the outside diameter of the mandrel (12), with the undercut (3) left.
