Abstract

The influence factors and rules of the forming limit of aluminum alloy axisymmetric part in the hot extrusion process were theoretically analyzed. Through setting up the mechanical model of the stress state in the hot extrusion process of aluminum alloy axisymmetric flange parts, obtain the expression of the stress state and the maximum diameter in flange region. At the same time, through the comparison of different stress conditions. The regulation of the pressure P in the outer of flange, the friction τ between the material and tool and the thickness t of flange region for the maximum diameter in flange region was analyzed, in order to offer theoretical basis for predicting the forming limit.
