Экспериментальное определение критерия разрушения при волочении высокоуглеродистой катанки

Abstract

The selection of acceptable destruction criterion for determining maximum deformation degree of highly carbonaceous rolled wire and the determination of its allowed value is realized on the basis of analysis of the existing destruction criteria which are used in the domestic theory and practice of working metals by pressure. The diagram of the procedure of destruction criterion value determination for selected material of rolled wire is represented. On the basis of given procedure of determination destruction criterion limiting value is determined the possible maximum degree of the summary deformation of highly carbonaceous rolled wire by the diameter of 5,50 mm with drawing wire for the cord with wire spiral insert. The application effectiveness of the developed criterion with the technological regimes calculation of competitive production product is proven.
