Abstract:A mesh-reconstruction technology of welding-plane is introduced based on Deform-3D and Pro/Engineer software. Applying the technology, the metal flowing behaviors, temperature fields and mandrel stress distributions during the whole extrusion processes of two hollow profiles are analyzed. The results show that, the reconstruction technology is effective for simulation the whole extrusion process (including dividing, welding and forming) of hollow profiles with irregular cross section. The mesh-reconstruction technology provides a new method to investigate the metal flowing behavior, die structure optimization, temperature distribution of ingot, die stress during welding stage of porthole extrusion.
