FIELD: manufacturing equipment for plastic working of cylindrical blanks with use of magnetic devices.
SUBSTANCE: inductor includes set of electrically connected in series metallic discs having insulated layers and radial cutout from inner opening till periphery. Radial cutout is in the form of sector with angle 120°. Each metallic disc has insulated layer only at one side and along its end surfaces and it engages by its non-insulated surface with non-insulated side of adjacent metallic disc on surface of sector with angle 120° for forming helix of double layer of metallic discs at their preliminary axial compression.
EFFECT: enhanced strength of inductor at the same thickness values of metallic discs and insulation.
