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 materials by means of pulsed magnetic field. Lower and upper support plates are fixed by annular cartridge located between them, on lower support plate there is a cylinder, annular disk is located between cylinder and annular cartridge, and inside disc cylinder there are sliders. Spring-loaded pushers are connected with lower intermediate plate. Between the upper support plate and the end of the cylinder there is a cylindrical inductor, inside and outside which there are throwable elements in contact with the elastic medium, which fills the cavity inside and around the cylindrical inductor. Above the upper plate on the posts there is a spring-loaded upper intermediate plate connected to the lower intermediate plate by tie-rods fixed on the axles.

EFFECT: broader technological capabilities of the device.
