摘要
为节省原材料和提高支撑轴的力学性能 ,提出了热锻、镦挤和反挤三道工序来成形支撑轴的新方法 ,采用有限元方法模拟和分析了挤压成形过程 ,设计了合理的预成形坯形状和尺寸 。
In order to reduce the waste of materials and improve proprerties of the product, a new process including hot forging, upsetting combined with extrusion and backward extrusion was proposed. The whole process of manufacturing the support shaft forgings was analyzed and simulated by FEM. According to the predicted result, the reasonable shape and dimensions of the preform were determined. The two sets of extrusion dies of manufacturing the support shaft were designed according to the actual conditions.
