从冲压成型理论出发,结合成型极限图(FLD)阐述冲压起皱机理,为分析起皱问题提供了思路,以某车型SUV侧围外板为例,对腰线后三角窗位置的起皱问题进行解析,并于同步工程阶段,借助AutoForm分析软件找到了一种解决该起皱问题的对策,产品实物证实了该方法的有效性,对于同类结构的产品或工艺提供了参考,具有一定的推广和借鉴意义.
Analysis and solution for wrinkle defect in the waist line of rear triangle window of body side outer panel
This paper based on the theory of stamping forming and explains the mechanism of stamping wrinkle in combination with forming limit diagram(FLD),which provides a clear idea for analyzing the wrinkledefect.Taking the side panel of an SUV model as an example,the wrinkle defects of the rear triangle window position of the waist line is analyzed,and a countermeasure to solve the wrinkling problem is found by means of AutoForm analysis software in the simultaneous engineering stage.The effectiveness of the method is verified by the product,and it provides a reference for the similar structure products or processes,and has a certain popularization and reference.
