FVM Simulation of Porthole Die Extrusion Process for a Large Caliber Aluminum Tube Profile

Abstract:

Aiming at the aluminum profile extrusion process of a large caliber aluminum tube with porthole die, this paper established the simulation models by using finite element method and finite volume method, respectively. The extrusion process was simulated by using the above two models. The advantages and disadvantages and the applicability of the two simulation methods in simulating large aluminum profile extrusion processes were compared. It is concluded that finite volume method is more suitable than finite element method for simulating aluminum profile extrusion processes with a severe deformation. In addition, the distributions of stress and strain and the material flow patterns in the large caliber aluminum tube extrusion process with porthole die were given in detail. The results can provide useful theoretical guidelines for the process and die design as well as process parameter optimal selection for large aluminum profile extrusion processes with porthole die.
