METHOD OF PRODUCTION OF AXISYMMETRIC BAR AND WIRE METAL PRODUCTS OF INCREASED ACCURACY

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to the treatment of metals by pressure and can be used in the manufacture of axisymmetric bar and wire products by drawing. Preliminary, the billet is formed into a billet, after which the billet is drawn through monolithic dies using a process lubricant. When drawing, the change in the radius of the metal product is taken into account due to the relaxation of residual stresses, the value of which is determined by the formula given.;EFFECT: accuracy of the products obtained is improved.;1 cl, 1 ex
