Inductor for magnetic pulse working of tubular metal articles
First Claim
1. An inductor for magnetic pulse working of tubular articles, comprising:
- a coil composed of flat conductors insulated from one another, said conductors each being made as a sector portion of an annular disc of less than one full turn, which sector portions are helically bent along the axis of said coil at a pitch that ensures a displacement of the ends of each conductor relative to each other by the axial length of said coil, said conductors being assembled into a multiple helix, and the ends of said conductors on at least one axial end of said coil being arranged in one plane substantially normal to the coil axis and circumferentially spaced relative to one another at substantially equal angular spaces or increments.

Abstract
Disclosure is made of an inductor for magnetic pulse working of tubular metal articles, wherein the coil is composed of flat conductors insulated from one another and manufactured in the form of at least a sector portion of an annular disc helically bent at a pitch that ensures a displacement of a conductor'"'"'s ends relative to one another by the length of the coil. Said flat conductors are assembled into a multiple helix. On one side, the ends of said flat conductors are arranged in one plane normal to the coil axis and circumferentially spaced relative to one another at equal angles.
Due to the change in the inductance from a value equal to the inductance of a portion of a hollow tubular conductor to that of a single-turn inductor whose turn has geometrical dimensions equal to the dimensions of the inductor coil, the inductor of the present invention makes it possible to carry out magnetic pulse working of large-diameter metal articles.
