摘　　要：针对带有翻边的汽车外覆盖件在冲压成形过程中出现的回弹问题,现以某车门外板为例,从冲压工艺方案、A级曲面重新补偿、模具结构等方面进行阐述,应用CAE全工序模拟分析技术进行方案虚拟验证,控制成形制件的回弹,并将验证方案在结构设计中实施,同时结合A级曲面补偿,重构加工数模用于现场加工。通过现场生产验证该方法的有效性,表明该方法可以有效控制汽车外覆盖件因翻边导致的回弹。In order to solve the springback of the automobile outer cover panels with flanging pro⁃cess during stamping forming,taking the door outer panel as an example,the stamping process scheme,A class surface compensation reconstruction,die structure were elaborated.The whole process simulation analysis technology of CAE was applied to verify the scheme virtual simulation,and the springback of parts was controlled,and the verification scheme was implemented in the structural design.At the same time,combined with the reconstruction of A class surface compensa⁃tion,the reconstruction of the machining digital model was used for field processing.The effective⁃ness of the method was verified by field production,which showed that the method could effective⁃ly control the springback problem that caused by the flanging of the automobile outer cover panels.
