DEVICE FOR SHAPING CASING TYPE "GLASS" BY MAGNETIC-IMPULSE STAMPING Russian patent published in 2021 - IPC B21D26/14 

FIELD: metal processing.

SUBSTANCE: invention relates to metal processing by pressure with a pulsed magnetic field of metal casing. Device for shaping a "glass" type casing by magnetic-pulse stamping contains a supporting plate with a central threaded hole and a cylindrical inductor, in which the supporting plate is fixed vertically by a frame tubular support with a rectangular section, rigidly connected to a rectangular base, which is rigidly connected to the supporting plate. Pressing mandrel is attached to the supporting plate coaxially with the central threaded hole. In the pressing mandrel inner cylindrical cavity, an ejection sleeve is placed along a sliding fit and a composite mandrel is fixed by a cylindrical protrusion, which is made in the form of a sleeve of two connected halves. In the supporting plate, the axle of the stripper is screwed through the central threaded hole, on which the ejection sleeve is fixed through the coaxial central hole. Built-up mandrel is fitted with a slip fit. On one side of the puller axis, the puller handle is fixed, on the other side, the puller tip. Pressing mandrel is located inside the cavity of the cylindrical inductor with a gap.

EFFECT: technological capabilities expansion.
