Keywords: copper; tri-branchtube; axialforcebulging; numericalsimulation1 Introduction With the aerospace, automotive, petrochemical and other industries quickly Received date :2007-05-25; Revision Date :2007 -08-10 Author: Zhang Yanmin (1970 ), female, Ph.D.,adidas climacool hose, Associate Professor E-mail: zhangmin70 @ 163. CO1TI development, energy conservation, environmental protection is an urgent task, tube parts to performance, structure,adidas climacool, light weight and has broad application prospects. Axial high-pressure liquid thin-walled tube bulging is one of the main production ],adidas la trainer, but the high-pressure liquid bulging equipment investment is high, demanding seal conditions, long process cycle and other factors so that the process has a certain limitations; development of low investment and artificial containers,adidas online shop, solid, viscous force transmission medium tube bulging axial compression technology to become a new bright spot. In this paper,adidas schuhe, copper is blank,adidas neo, blank polyurethane compression began to start filling up to the end of the tooth, rough contact surface with the punch pressure increased gradually filling in the final stages of tooth contact with the concave mold surface rapid increase in contact force to squeeze the end of the maximum. 5 Conclusion of advanced manufacturing technology of cold forging forming process not only can improve material utilization and can reduce the process of working hours, lower production costs, the production of small precision parts ideal for sophisticated processing technology. By car differential bevel gear cold forging process the finite element numerical simulation to optimize the design of the mold to ensure the quality of cold forging, the correct and reasonable reflection of the rough material of the plastic forming and flow pattern.
