Simulation Study on Influence of Forming Process Parameters on Backward Extrusion Height of 6061 Aluminum-alloy Wheel

摘要：

　　Backward extrusion process of aluminum-alloy wheel forging is analyzed by the finite element method.The influence of punch speed and forming temperature on the backward extrusion height of 6061 aluminum alloy wheel is discussed.Studies show that the backward extrusion height increases with increasing forming temperature,and with decreasing punch speed at the same deformation load.It is indicated that when the ranges of forming temperature is from 450 to 500℃and the punch speed is 0.5-1 mm/s,the aluminum alloy wheel has the optimal forming quality.The analysis and conclusions in this paper are helpful in developing the hot extrusion technology specification of 6061 aluminum alloy.
