Driver plate for electromagnetic forming of sheet metal
Abstract:
A multi-layer driver plate is disclosed for use in electromagnetic sheet metal forming operations. In one embodiment, the driver plate comprises a first layer characterized by low electrical resistivity and thickness for inducement and application of a suitable electromagnetic forming force, a second layer comprising an elastomeric material for compressing a sheet metal workpiece against a die surface and then regaining its original pre-forming structure, and a third layer interposed between the first layer and the second layer to protect the EMF force providing layer and to provide overall strength and durability to the EMF driver plate.
