Abstract：

Based on the analysis of the forming process for pressure accumulating tube in automobile accumulator, the application of rigid viscoplastic finite element technology and the evaluation standard of the forming load, three technological parameters (billet temperature, die preheating temperature and punch speed) influencing the forming process were simulated and analyzed through the orthogonal experiments by Deform-3D software. The optimal technological parameters obtained from experiments are billet temperature 850 ℃, die preheating temperature 300 ℃, punch speed downwards 16 mm·s-1 during the warm extrusion process and punch speed 8 mm·s-1 for cold extrusion. The numerical simulation results show that both the temperature of warm extrusion billet and punch speed have great effects on forming load, while the effect of die preheating temperature is relatively small. In order to reduce the effects of temperature on the forming process, the preheating temperature for the die should be relatively high temperature; and then during the cold extrusion, the punch speed should be relatively small. As a result, the qualified forming parts were obtained from actual extrusion with above parameters.
