摘　　要：通过对双杯形件的成形工艺特点的分析,提出了工艺方案,并建立了有限元模型。采用锻造分析软件QFORM 2D/3D对其冷挤压成形过程进行了数值模拟分析。讨论了成形过程中的载荷—行程及应力—应变的分布曲线,分析了导致模具损坏的原因。提出了优化方案,有效地保护了模具。这对双杯形件的生产具有指导意义。Through the analysis of the characteristics of forming technology for the double cup shell, the process scheme was put forward, and a finite element model was established. The cold extrusion forming process was numerically simulated by forging analysis software QFORM 2D/3D. The curves of stroke-load and stress-strain distribution of the forming process were discussed. The cause of the die damage was analyzed. An optimization scheme was proposed, which effectively protected the die. Which has guiding significance to the production of the double cup shell.
