Abstract
Abstract 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
An inductor for forming metals by the pressure of a pulsed magnetic field, comprising: a magnetic field concentrator split in at least one plane; at least two dies of said concentrator; said dies of said concentrator being spatially adjustable relative to each other; a coil located on at least one said die of said concentrator; said coil inducing eddy currents in said concentrator; at least one opening made in said concentrator, having an axis extending along said plane in which said concentrator is split and said axis being perpendicular to the longitudinal axis of said magnetic field concentrator; a surface of said opening, concentrated whereon are eddy currents inducing eddy currents in a workpiece; a means for electrically insulating said dies of said concentrator.
Claim 2
Dependent Claim
124 words
An inductor for forming metals by the pressure of a pulsed magnetic field, comprising: a magnetic field concentrator split in at least one plane; at least two dies of said concentrator; said dies of said concentrator being spatially adjustable relative to each other; a coil located on at least one said die of said concentrator; said coil inducing eddy currents in said concentrator; at least one opening made in said concentrator, having an axis extending along said plane in which said concentrator is split and said axis being perpendicular to the longitudinal axis of said magnetic field concentrator; a surface of said opening, concentrated whereon are eddy currents inducing eddy currents in a workpiece; a means for electrically insulating said dies of said concentrator.
