Abstract
A high-current loop connected to a pulse transformer is made as a magnetic field shaper with an opening to receive a metal part which is to be shaped. The high-current loop has a slit extending radially with respect to this opening in the direction toward conductor blocks connecting it to the secondary winding of the pulse transformer. The high-current loop can also be made as an exchangeable magnetic field shaper, made up of one block that is divided in the area of the opening, preferably consisting of copper or aluminum, that has an opening for the metal part which is to be shaped. This design of a high-current loop is used to receive pipe-shaped metal parts that are to be shaped, that, outside of the deformation, have a larger outside diameter, that receive a metal part with a larger volume, and/or that are pre-bent in a serpentine fashion.
