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