DEVICE FOR ELECTROIMPULSE PRESSING POWDER Russian patent published in 2019 - IPC B22F3/87 

FIELD: technological processes.

SUBSTANCE: invention relates to electropulse pressing of a powder. Device contains two pulsed energy sources, a loading device, a metal holder with a matrix of insulating material, the upper movable punch inserted into the rod, which passes through the upper base, the lower punch mounted on the lower base, a plate with two rods and two bushings, on which a holder with a matrix filled with powder is fixed, an inductor and a pusher plate located below the bottom base and configured to move the lower punch up through the hole in the bottom plate. Bushings are spring-loaded and slidable vertically along rails mounted on the lower base. First pulsed energy source is connected to the powder filling, and the second pulsed energy source is connected to the inductor. Boom is mounted on the upper base, on which a limit switch is fixed at a predetermined height, connected to the control system of the second pulsed energy source, and a plate in the form of a ledge is mounted on the rod, capable of closing or opening the limit switch.

EFFECT: increased product density is provided.
