此文对轴对称杯杆形零件进行了复合挤压的实验研究,根据其变形规律及金属流动特点,提出了金属流动模型,并用上限法理论进行了分析、计算。理论计算值与实验测定值能较好地符合。
In this paper, an experimental study on the co-extrusion of axisymmetric cup-rod-shaped parts has been carried out. According to the deformation law and the characteristics of metal flow, a metal flow model is proposed and analyzed and calculated by the upper bound theory. Theoretical calculations and experimental values can be better.
