摘　　要：基于MSCSuperforge软件平台,对宽展挤压中金属材料在模具内的流动进行了数值模拟分析,研究了宽展模参数:模具入口宽度、模具出口宽度、宽展模高度以及工作带基准长度和模孔位置等因素对金属流动的影响。Based on a new metal forming simulation package,MSC Superforge,the metal flow inside the die in the course of spread extrusion has been simulated and analyzed.The influences of the die parameters including the inflow entry width,outflow exit width,cavity height,basic working land length and flowing hole position on the metal flow have been studied.As a result,the data from that numerical simulation have a significant contribution to the optimization of the design of extrusion dies.
