Numerical Simulation Optimization Research of Cold Extrusion Forming for Injection Head

Abstract:

In order to obtain high-quality injection head, cold extrusion forming is adopted. Based on the study of forming technology for the injection head, reasonable process flow, cold extrusion pre-treatment process and boundary conditions are designed. Two finite element models in forward extrusion and backward extrusion forming ways are established. Taking DEFORM as the platform, the numerical simulation of forming process is carried out. Through simulation, the distribution of strain field, stress field and velocity field in the process of cold extrusion forming is preliminarily forecast, the merits and defects of two kinds of forming processes and the force state of mold are compared , the optimal forming scheme is determined.
