METHOD OF MULTIPLE PLASTIC DEFORMATION AXISYMMETRIC rod and wire METAL

摘要

A method of multiple plastic deformation of the wire rod and axisymmetric metal products, comprising a preliminary forming on the article and the subsequent drawing zahvatki through monolithic die, characterized in that the total extract limiting conditions was determined from the retention of strength of metal to the formula: total λ- extractor at multijunction drawing; n - number of transitions reusable plastic deformation drawing - parameter characterizing the mechanical properties being treated nd metal; ψ - coefficient determining the proportion of residual stresses energy; E, μ - the modulus of elasticity and Poisson's ratio of the treated metal respectively; σ-treated metal strength limit; σ- deformation resistance of the treated metal; α- angle forming die monolithic working cone.
