Abstract:
1. A device for electromagnetic high energy pulse deformation of workpieces of an electrically conductive material, comprising a deformation tool including a coil carrier and at least two partial coils arranged on said coil carrier; at least one surge current generator to which said partial coils are connected so that magnetic fields of said partial coils superpose to form a resulting magnetic field which acts on the workpiece, said partial coils being formed as spiral coils which are formed identically with respect to inductivity, electrical resistance, winding number and shape, and each of said partial coils extending on said coil carrier from an inner starting point in an identical form and with a corresponding identical distance to a neighboring one of said partial coils in a spiral-shaped manner outwardly.
