Abstract：

By means of the FEM software HyperXtrude, steady-state simulation analysis on the extrusion process of prolate aluminum profile was conducted, the velocity field and the deformation field of metal flow were acquired. The reasons of non-uniform velocity and larger deformation at the exit of profile were analyzed, and the initial die structure was improved. Restrictive blocking was applied in the thick area part of the profile to slow down the flow velocity and to make flow velocity of whole body more uniform. The feeding in each part of the profile was balanced by adjusting the sizes of the portholes, and the problem of the non-uniform distribution of the metal in the extrusion process was solved effectively. The results of simulation for the improved die are in accordance with the practical production requirements with SDV decreased by 70.2%.
