Abstract
Disclosure is made of an inductor for working metals by the pressure of a pulsating magnetic field, which comprises a magnetic field concentrator with an insulating slot. The concentrator has a cylindrical surface, whereon there is arranged a winding which induces eddy currents in the concentrator, and a surface, whereon there are concentrated eddy currents which induce eddy currents in the workpiece. The concentrator is provided with a conducting compensation rod overlapping the insulating slot, which rod is insulated from the concentrator and received in an opening extending along the slot in immediate proximity to that surface of the concentrator where there are induced eddy currents which induce eddy currents in the workpiece. The proposed inductor design makes it possible to produce a uniform magnetic field which, in turn, produces electrodynamic forces that work a blank so as to improve the quality of products, as compared to conventional working techniques.
