DEVICE FOR MAGNETIC-PULSE PUNCHING Russian patent published in 2019 - IPC B21D26/14 

FIELD: technological processes.

SUBSTANCE: invention relates to metal forming by cylindrical shells and sheet metals by means of pulsed magnetic field. Support plates are fixed on posts, spring-loaded intermediate plates with cylindrical ledges are installed between support plates, upper and lower plates, which are included in cavity of support plates and have possibility of movement along posts and support plates. Inside the annular thrown element there is an elastic medium contacting the outer side surface with the inner surface of the annular thrown element, and end surfaces – with the fixed support plates and projections of the movable intermediate plates. At the same time puncheon holders with puncheons are fixed on intermediate plates, and on upper and lower plates of matrix. Expanding technological capabilities of device.

EFFECT: device for magnetic-pulse forming is proposed.
