Abstract

The die or mould used for extruding aluminum wallboard profile is in serious work conditions, so it is easy to appear drawbacks in the mould such as non-uniform stress and strain distributions, crack initiation and propagation, elastic warp, and even plastic distortion. As we know, the extrusion die or mould is subject to complex loads including the extrusion pressure, friction and thermal load, which make the mould complicated and hard to be designed and analyzed by using conventional analytical method. In this paper, we applied Deform-3D, FEA (Finite Element Analysis) software used frequently in all engineering fields, to simulate three-dimensional extruding process of aluminum profile. The simulation results show that the deformation increases gradually from inside to outside. Exterior deformation contour distribution is relative uniform since the influence of inner holes on deformation is small, and the contour form is regular and similar with the shape of the mould. However, the interior deformation contour is irregular as the influence of holes with basically symmetric equivalent curves. At the middle of the mould, the deformation reaches the largest, it reaches 0.633mm. The deformation of the mould can be reduced by increasing the distance between two holes or increasing thickness of the mould. Experiment result accords with simulation. The simulation process and results ensure the feasibility of finite element method, providing the support for mould design and structural optimization.
