Sigma Analysis and Optimization for the Process of Automotive Aluminum Alloy Door Inner Panels

为快速获得可靠的铝产品成形工艺参数,以某汽车铝车门内板为研究对象,结合产品的结构特点,利用AutoForm软件进行材料、工艺建模和分析,明确其成形缺陷的风险区域,然后将坯料尺寸、压边力、拉延筋的阻力系数作为工艺优化设计变量,通过Sigma模块进行工艺优化分析,累计迭代运算114次,获得了符合成形质量评判标准的最佳参数组合。经生产验证,按照最优的参数组合所生产零件成形质量良好。

To get reliable forming process parameters for aluminum products,the inner panel of an automotive aluminum door is taken as the research object.Considering the structural characteristics of this product,the process modeling and analysis are initially performed using the AutoForm software to identify the risk areas of its forming defects.Subsequently,the blank size,binder force,and the resistance coefficient of the drawbead are adopted as the design variables for process optimization.The process optimization analysis is implemented through the Sigma module.After a cumulative total of 114 iterative operations,the optimal parameter combination that complies with the forming quality evaluation criteria is obtained.Production verification shows that the formed quality of the stamped parts is excellent according to the optimal parameter combination.
