Abstract

Disclosure is made of an inductor for working metals by the pressure of a pulsating magnetic field, wherein on the outer surface of a concentrator, which has a working opening to receive an article to be worked and a radial slot, there are provided annular grooves, the spacings between the annular grooves forming stiffening ribs of the concentrator; laid in said annular grooves are flat helical sections of a winding, the beginning of each section enveloping an electrically conducting rod arranged in a bore extending through the concentrator, being parallel with the axis of the working opening and being next to said annular grooves; the ends of each flat helical section are interconnected in parallel by means of a bus; in said concentrator ribs, there are provided threaded holes to receive screws whose butt ends press upon the electrically conducting rod.

Dependent claims

An inductor, for working metals by using the pressure of a pulsating magnetic field, comprising:

a concentrator with a working opening to receive an article to be worked, a radial slot which connects the working opening with the outer surface of the concentrator, annular grooves provided on the outer surface of the concentrator, each annular groove receiving a flat helical section of a winding, and a bore provided in the body of said concentrator next to the annular grooves and parallel to the axis of said working opening;
ribs of the concentrator disposed between said annular grooves;
an electrically conducting rod tightly inserted in said bore and enveloped by the beginning of each said flat helical section of the winding;
screws received in radial threaded holes provided in said ribs of the concentrator, the butt ends of said screws pressing upon said electrically conducting rod;
and a collecting bus for parallel interconnection of said flat helical sections of the winding.
