Abstract

This paper describes design and analysis techniques of cold forging process for precise producing of T-200 type spider made of SCr420H by utilizing pneumatically operated enclosed die set. Since deducing feasible closing force is an important factor to optimize entire pneumatically operated cold forging system, a series of FE analyses with varying the number of gas cylinders has been carried out to investigate the influence of closing force upon the direction of applied load at die surfaces. It also reveals the optimum distribution of the gas cylinders in terms of the flatness of upper/lower plates.
