Abstract

Considering the advantages of the press process as compared to the machining process, the making good utilization of work piece materials and the saving of production time, the Press machine associated with press form tooling is increasingly served for complicated shape parts production. The sheet-extrusion is the most important metal-forming process, which controls the material flow to fulfil the extruded shape. By using this process, the complicated extruded-shape parts could be manufactured without the machining process. Owing to the piping defect, however, the complicated extruded-shape parts are limited in the sheet-extrusion process. In this study, the finite element method (FEM) is used to investigate the piping feature. In addition, a relationship between extruded shape and piping defect is also examined. The laboratory experiments are performed to validate the accuracy of FEM simulation results. Based on the stress distribution and velocity analysis, the relationship between extruded shape and piping defect could be clearly identified. Furthermore, The FEM simulation results show good agreement with the experimental results with reference to the extruded shape and piping defect. ฉ Published under licence by IOP Publishing Ltd.
