ELECTROMAGNETIC FORMING DEVICE

WIPO Patent Application WO/2019/077789

A1

The purpose of the present invention is to enable accurate formation of an elongate member while suppressing the occurrence of a shape defect. An electromagnetic forming device (1) is provided with an electromagnetic coil (2), and a forming mold (4) which is disposed along the electromagnetic coil (2) and provides an elongate material to be formed with a formed shape, wherein an electromagnetic force generated by means of the electromagnetic coil (2) is caused to act on the material to be formed and the material to be formed is pressed onto the forming mold (4). In the electromagnetic forming device (1), the forming mold (4) has a cross sectional shape that varies from one end to another in a longitudinal direction of the material to be formed. The forming mold (4) is formed such that, as the material to be formed is moved parallel to the longitudinal direction, the shape of the material to be formed is gradually changed to a desired shape.
