METHOD OF MAKING INDUCTOR FOR MAGNETIC PULSE METAL WORKING AND APPLIANCE FOR MAKING SAID INDUCTOR BY BENDING Russian patent published in 2012 - IPC B21D26/14 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming using magnetic appliances. Conductive coil is shaped to solid flat blank with conductive plate paths. Holes and grooves are made in every plate between path and central bore to make arbitrary current lines extending over all plate contour. Extreme conductive plates are furnished with connection terminals arranged in parallel while adjacent plates are connected via jumpers to make current distributor. Said jumpers are bent radially at points equidistant from aligned axes of central holes. Then, conductive plate surfaces are electrically isolated so that their internal and external contours overlap and clamped to contact. Proposed appliance comprises foot to support board with recesses for fitting conductive plate, bending mechanism made up of ledge coupled with lever and articulated with foot strut, and cylindrical pin arranged in plate bending zone that has axis aligned with hinge axis and perpendicular to lever axis and diameter that allows jumper radial bending.

EFFECT: expanded performances.
