An apparatus for metal forming under the pressure of pulsed magnet field comprises coils which are connected in series by means of flat buses, the extreme coils being provided with flat outputs arranged in parallel to one another along the coils; the flat buses are disposed intermediate the flat outputs and are insulated therefrom, with each of said flat buses being formed with a slot facing the coils and overlapped by the flat outputs. Such apparatus construction permits its efficiency to be increased 25 to 40 percent.

Apparatus for magnetic forming of metals

An inductor for forming metals by the pressure of a pulsed magnetic field comprises a magnetic field concentrator with a coil inducing eddy currents therein, the concentrator being made up of electrically insulated dies with an opening for the workpiece, so arranged that the plane in which the concentrator is split extends along said opening. Such a design of the inductor permits improving the power characteristics thereof, simplifies its operation, extends its service life, and enhances its efficiency. It also permits forming a wide variety of components.

Inductor for forming metals by the pressure of a pulsed magnetic field

Disclosure is made of an inductor for magnetic pulse shaping of metals, wherein on the outer surface of a concentrator, having a radial slot and an opening to receive an article being worked, there are provided flutes with windings disposed therein; in the radial slot zone, the concentrator ribs are provided with rectangular-shaped grooves whose depth is equal to that of the flutes, said grooves extending perpendicularly to the plane of the radial slot and receiving electrically conducting segment-shaped inserts overlapping the radial slot and insulated from the concentrator by gaskets.

Inductor for magnetic pulse shaping of metals

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.
