| 摘 要： | 采用物理模拟技术对镦，挤，摆辗复合工艺进行了实验研究。用视塑性法研究了变形体子午面内金属的流动规律，从而阐明变形方式，进给时、工件原始高径比、变形温度及变形量对正反挤出长度及法兰盘外缘形状的影响，对大量实验数据进行回归处理后，得出了根据产品尺寸选择最佳毛坯尺寸和最佳变形方式的经验曲线为复杂零件成形提供实验依据。

| Abstract: | in this paper, a experimental study of upsetting-extrusion-rotary forging compound pro-cess is made by using physical simulation technique. The flowing law of the metal in the meridian surfaceof the deformed body is investigated by using visioplasticity method. As a result, the effect of deformationmodes, feeding amount, initial aspect ratio of the workpiece, deformation temperature and degree ofdeformation on the fomard and backword extrusion length and flange profile are clarified and the empir-ical curves for selecting optimum blank demensions and deformation mode are found out by applying regression method to a large amount ofexperimental data.The experimental foundation of complex parts are provided. |
