Pulse electromagnetic forming apparatus and method for forming a dish from a flat plate

摘要

(57) Abstract Essentially the electromagnetic forming device which forms in the dish which possesses 3 dimensional pattern is offered the even metal plate. This device impulse magnetic power in order to make the mold and formation coil system and the aforementioned plate deform which possess the formation surface which possesses the form which corresponds to aforementioned 3 dimensional pattern (PMF) passing by the formation coil system in order to generate, possesses with the electric discharge circuit which discharges the electric current impulse whose period is strong briefly.
