Numerical Simulation of Hot Extrusion Process for Aluminum Alloy Rod

The hot extrusion process and die design of aluminum alloy rod have been analyzed in the text.The new hot extrusion technology which uses bar backward extrusion and head forward extrusion has been adopted,so that the material utilization and production efficiency have been greatly improved.The Deform-2D software has been carried out to numerically simulate the hot extrusion forming process of aluminum alloy.Through the numerical simulation of extrusion process of aluminum alloy rod,the changes of the material internal temperature field,strain field,and the plastic strain field parameters have been obtained.The practical test results show that the rod can be extruded by hot extrusion forming.
