Abstract
In order to reveal the crux of technology problem existing in the extrusion formation to seamless tube of aluminum alloy, the aluminum alloy 7075 was taken as example, and through numerical simulation of finite element method(FEM), technology parameters which impact the extrusion formation of aluminum alloy seamless tube were analyzed. The results show that with the increase of the extrusion velocity, the extrusion loading increases sharply and the uniformity of metal forming flow decreases in tube extrusion process. According to the analysis, at the forming conditions of temperature 430°C and extrusion speed 2 mm/s, the large seamless tube of aluminum alloy is formed and a fine surface quality is achieved, which meets the application criterion.
