| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper describes an electromagnetic forming technique for conical springs of electronic parts and its experimental results. When an impulse current from a capacitor bank passes through a flat one-turn coil, a magnetic flux is suddenly generated around the coil. Eddy currents are induced in a insulated copper sheet (or overlapped aluminum and copper alloy sheets) fixed between the coil and a die. Magnetic pressure asts on each sheat. The copper or copper alloy sheet is sheared and formed for conical springs. The formed springs shrink in a plane. | |
