摘要/Abstract

摘要： 柔性翻边成形是一种局部连续加载的翻边新工艺,其工艺规律和规划方法尚不完善.结合航空钣金结构件的特点,设计特征翻边件,基于Abaqus平台进行柔性翻边成形工艺的仿真研究,总结翻边道次数、各道次角度分配、滚轮直径和滚压速度等关键工艺参数对成形质量的影响规律.综合考虑成形效率,优化工艺参数设计,并进行试验验证.结果表明:对关键工艺参数进行优化设计,能够低成本地显著提高柔性翻边的成形质量,并在一定程度上提高成形效率.
关键词: 柔性翻边成形, 钣金件, 工艺参数, 成形质量, 成形效率
Abstract: Flexible flanging is a novel forming process by local continuous loading, but its process law and planning method are not perfect. Based on the characteristics of aviation sheet metal parts, the feature flanging parts were designed. Simulation of flexible flanging was conducted on the Abaqus platform, and the influence of key process parameters such as rolling pass numbers, the angle distribution of each pass, roller diameter, and rolling speed on forming quality were obtained. Considering the forming efficiency, the process parameters were optimized and verified by experiments. The results show that the forming quality of flexible flanging can be significantly improved with low cost by optimizing key process parameters, and the forming efficiency can be improved to a certain extent.
Key words: flexible flanging, sheet metal part, process parameter, forming quality, forming efficiency
