ELECTROMAGNETIC FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic forming apparatus which can provide increased productivity while avoiding flowing of large current through a drive circuit for inductors including a capacitor. SOLUTION: A plurality of inductors 21(1)-21(n) (n is a natural number.) are respectively connected between electric discharge terminals 25(1)-25(n) and a grounding terminal 250. The capacitor 24 is charged with a proper power unit and one terminal of the capacitor 24 is respectively connected to the discharge terminals 25(1)-25(n) through a plurality of switches 22(1)-22(n). On and off of the switches 22(1)-22(n) is performed by being turned on by the supply of a low-current and low voltage trigger current and the trigger current is supplied from a proper trigger power source through trigger changeover switch 23.
