Portholes Die Extrusion Process Numerical Simulation and Optimal Die Design

Abstract:

In the paper, extrusion process of hollow aluminum profile was simulated using DEFORM-3D; the metal flow velocity of setting baffle-blocks before and after is compared. Three kinds of welding chamber depth of 10 mm, 13 mm, 15 mm were used respectively for extrusion process simulation and got die load varying pattern. Also the strain field and temperature field were analyzed. The results show that the metal flow velocity was more well-distributed by setting A、B、C、D baffle-blocks. When the weld chamber depth is 13 mm, the die load is the smallest. By analyzing the strain field and temperature field,The results showed that the major cause of metal temperature rising in the extrusion process is deformation energy generating in the process of metal plastic deformation.
