Simulation Analysis of Upper Mould Base for High Speed Punch
Based on two kinds of upper mould bases real structures of high speed punch, the structure was simplified and simulation models were built in next step. According to working condition of actual temperature changes and moving characteristics for the high speed punch, the thermal boundary conditions, the thermal- stress coupling conditions and mechanical constraint conditions of the simulation model were set up, and the deformation for the guiding hole of upper mould base were got through simulation analysis. Through the comparison of the two simulation results, it illustrated that the improved upper mould base is more suitable for high speed punch with high punch frequency condition.
