Abstract
In this paper, based on elastic-plastic and thermal-stress coupling finite element method (FEM), the centrifuge pipe mould was molded by Pro/E, and imported into the MARC after meshing, and performed finite element analysis to extrusion stability and the process of hot extrusion by MARC. By summarizing the 3D deformation regulation of the hot extrusion centrifuge pipe mould, the stress changing and mechanical property parameters during the process of hot extrusion , providing reference for the design of equipment in radial hot extrusion. At last, the study could be useful for the device design of radial hot extrusion of the centrifuge pipe mould. At the same time, this method could be use to analyze the other relative thermal extrusion processing.
