摘要
以刚塑性有限元分析为基础,对镁合金扇形零件的挤压成形工艺进行了模拟分析,制定出扇形零件的成形工艺,即镦挤-反挤压复合成形工艺。镦挤制坯工艺优化坯料结构,反挤压工艺成形零件。根据数值模拟的工艺参数进行试验研究,成形出符合要求的零件。
Upon rigid-plastic FE analysis the numerical simulation on extrusion technology of magnesium alloy fan-shaped part has been done to formulate the fan-shaped part forming process which is upsetting extrusion-anti-extrusion compound forming process. The upsetting extrusion process optimized the blank structure, and the anti-extrusion process formed the part. The experiment was done by the parameters of numerical simulation, and qualified parts were obtained.
