Механіка процесу формування внутрішніх шліцьових поверхонь у глухих отворах холодним деформуванням

Abstract

In this paper the process of forming internal spline surfaces in blind holes by the cold plastic deformation method (CPDM) is investigated. Distribution of hardness in meridian section of workpieces that has allowed to prepare the initial information for calculation the stress-stained state (SSS) in view of hardening metal is received. The stress-stained state (SSS) is investigated and the deformability of metal is estimated at forming internal spline surfaces in blind holes by the cold plastic deformation method (CPDM). The experimentally-calculated method was attracted for calculation of the stress state, this method combining the method of hardness and an engineering method. Distribution of tensor stress components and the stress state index are obtained. The used resource of plasticity at forming internal spline surfaces in blind holes by the CPDM is estimated. The most advantageous load scheme has been determined.
