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

FIELD: technological processes.

SUBSTANCE: invention relates to metal forming by pulse magnetic field of cylindrical shells and sheet materials. On the side of the inner and outer surfaces of the cylindrical inductor there are annular throwable elements and an elastic medium contacting with them, on the lower support plate there is a cylinder, in the cylinder cavity and the cavity between the cylinder and the annular cartridge there installed with possibility of axial movement are contacting with the elastic medium spring-loaded slides with pushers connected to the intermediate plate. Intermediate plate is installed between lower support plate and lower plate with possibility of movement on posts. Puncheon holder with the puncheon is fixed on the intermediate plate, and on the lower plate the matrix with guides and puller.

EFFECT: broader technological capabilities of the device.
