DRAWING MACHINE Russian patent published in 2010 - IPC B21C1/04 

FIELD: process engineering.

SUBSTANCE: die-head blocks (1) with drawing dies (2) are mounted along the feed of every wire (3). Pulsating lengthwise strains that reduce drawing friction result from making intermediate gear device consisting of drive crankshaft (5), rods (6) and two frames (7)moving in lengthwise direction and supporting clamps (8) that grip wise in feed direction and let it pass in back direction, and generate pulsating lengthwise strains in said wire two times per one crankshaft revolution. At the same time, load on drum (4) is reduced, said drum making the main drive member of drawing machine.

EFFECT: simplified design.
