ABSTRACT:
There is disclosed herein an apparatus for electromagnetic forming of a workpiece with enhancements that increase the durability and overall efficiency of the solenoid coil. The apparatus includes reinforcement members dispersed through the solenoid coil and a cooling system. The apparatus also includes a shaper that varies in girth effectively acting as a force concentrator. The electromagnetic forming device is also capable of incrementally heat treating the workpiece and reducing residual stresses in the workpiece. The invention further discloses a more efficient way of manufacturing the solenoid coil.
