METHOD OF PRODUCING TRIMETAL ROD AND WIRE ARTICLES Russian patent published in 2018 - IPC B21C1/20 B21C3/00 

Abstract RU 2669260 C1

FIELD: technological processes.

SUBSTANCE: invention is intended for the production of trimetallic bar and wire products by drawing. Proposed method comprises forming hook on article with sharpened and conical sections and drawing through tapered channel of monolithic drawing die. Die is used with a predetermined angle of inclination of the generatrix of the conical channel to the axis of drawing.

EFFECT: invention makes it possible to reduce the energy consumption of the drawing process by using a dredge with an optimal angle of inclination of the generatrix of the working channel to the axis of drawing.
