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

FIELD: technological processes.

SUBSTANCE: invention relates to sheet metal forming by electrodynamic action of magnetic-pulse device. When pulse current passes through the actuator, the lower intermediate plate moves to the lower plate and the puncheon is exposed to the workpiece for cutting or punching. When the lower intermediate plate of the rod is moved, the upper intermediate plate is exposed, and the puncheon performs squeezing of the workpiece installed on the second matrix.

EFFECT: enlarging technological capabilities of the device for magnetic-pulse forming due to simultaneous punching of two blanks.
