Numerical Simulation Analysis on Porthole Dies Extrusion of Aluminum Mini-Thin Harmonica-Shaped Tube

Abstract:

This paper describes a 3D-deform simulation of porthole die extrusion process for producing harmonica-shaped tubes used for a cooling system of automobiles. Designing the related structure of the porthole die and observing the simulation results, the study was designed to evaluate the welding effect when the length of bearing exit take different values.The mean pressure and exit velocity at the welding plane are analyzed at the same time. The welding effect is determined by the mean pressure at the welding plane .The behavior of metal flow in the container is analyzed in this paper. Through the above analysis, the best structure and size can be obtained in the process of deformation so as to obtain the better machanical properties.
