Patent ID: 7540180

Claim:
An apparatus for electromagnetic forming a workpiece, comprising: a multi-turn solenoid coil operative to generate an electromagnetic force against said workpiece; a housing unit supporting said coil; an electromagnetic pulse generator connected to the coil and operative to generate an electromagnetic field; a plurality of reinforcement members disposed through said coil and operative to prevent deformation of said coil during a forming operation; a cooling system for passing coolant across the coil; said multi-turns in said coil separated by a predetermined distance wherein adjacent turns of said multi-turns in said coil are separated by a gap larger than 2 millimeters; said coil operative to generate a predetermined amount of heat energy so as to heat said workpiece according to a predefined heat treatment process; and said coil includes a plurality of apertures extending through the turns of the coil along transverse, longitudinal or radial directions of said coil and that are operative to receive said reinforcement members.
