A New Model for Predicting of Stresses on the Compound Extrusion Container

Authors: , , ,

Abstract: The extrusion process is widely used for forming aluminum and titanium alloy parts or products. A material is fed into the extrusion container for pushing through a die to create parts with a fixed cross-sectional profile. The extrusion container is one of the most key components that supports extremely high pressure (>700MPa) in the extrusion process. Therefore, the compound extrusion container is designed for reduce the peak of stresses to increase its reliability. The stresses distribution is largely depended on the interferences and layer thicknesses. In this paper, a new analytical model based on Direction Displacement Method (DDM) is proposed for predicting the stress distribution on the multi-layer container. The stresses distribution on the container after assembly and normal working are computed by using this model. Four cases are studied to verify the fidelity of the proposed model. Finally, discussions and concluding remarks are also given.
