摘要：

基于Autoform有限元仿真分析软件，对两款不同SUV车型的后侧门内板进行冲压成形性分析。通过对轮毂处板料线的整合优化，实现两款车型后侧门内板的原材料边线重合，同时也兼顾了两个产品的成形性能指标。对CAE分析得出的两个后侧门内板的原材料进行排样，之后进行开卷落料模设计，通过对模具定位柔性化创新设计，实现一套开卷落料模通过切换定位来满足两个车型的后侧门内板落料工作。结构设计采用浮动刀先进工艺结构，大大缩减了模具尺寸。最终制造的模具成功应用在实际生产中，降低了新项目中的模具开发成本，缩短了开发制造周期，提高了生产效率。

Based on finite element analysis software Autoform，the stamping formability analysis on the rear side door inner panel of two different SUV vehicle models was conducted, and after the integration and optimization of the plate line at the wheel hub area, the coincidence of edge lines of the raw materials for the rear side door inner panel of two vehicle models was realized, and simultaneously considering the formability performance indicators of both products. Then, the raw materials for the two rear side door inner panels obtained from CAE analysis were arranged, and the design of the decoiling-blanking die was conducted. Furthermore, through the flexible and innovative design of die positioning, the material dropping work for the rear side door inner panel of two vehicle models was realized by switching positioning with a set of decoiling-blanking die. The results show that the structural design adopts advanced floating cutter, greatly reducing the die size. The final manufactured die is successfully applied in the actual production, reducing the die development cost in new projects, shortening the development and manufacturing cycle, and improving the production efficiency.
