Зміцнення поверхневого шару деталей машин поверхневим пластичним деформуванням. Зміцнення поверхневого шару валу 7.45.АС.12 обкочуванням роликом

Abstract

In this master's qualification work the modernizova-tion process technology machining the workpiece for the manufacture of "Val 7.45.АС.12." In the technological part of the specified type of production and form of work, an analysis of technological design details selected method of manufacturing workpiece based on feasibility study made calculations of allowances for processing, made the choice of finishing and roughing technological bases designed technological process of machining, and also performed dimensional analysis process. The operation shaft surface finishing of the proposed obkochuvannya roller, which allowed us to obtain hardened surface layer. The process obkochuvannya modeled using LS-DYNA and studied the stress state after the process obkochu-vannya. Results of proven international scientific conference and published abstracts. In addition, preliminary design completed machining station for this program and determined the reduced number of machines designed and workers at the site. In the graphic part is designed drawing details, drawing blanks, graphic workpiece machining route details and schemes to the table to explain the dimensional analysis process, posters on the study of the stress state after obkochuvannya details. The measures of safety and life safety.
