FIELD: technological processes.
SUBSTANCE: invention relates to the processing of metals by pressure and is intended for the production of rods and wire by drawing. Method includes pre-forming on the extruded billet a bite with pointed and conical sections and subsequent drawing through the working channel of a monolithic die. Exception to the probability of a breakage of the workpiece in the process of its drawing is ensured by the fact that the limit drawing during drawing is governed by a mathematical relationship that takes into account the resistance to deformation of the pulled metal, strength, safety factor, reduced die angle and other technological characteristics.
EFFECT: ensured elimination of the possibility of a breakage of the workpiece.
