摘要：

运用数值模拟与实体实验相结合的研究方法，设计并优化出一种两道次渐进成形外缘翻边路径，相较于单道次成形，该路径适用的加工范围更广。研究结果表明，使用圆弧直线两道次渐进成形外缘翻边路径，可以加工单道次无法成形的毛坯直径较大的翻边制件，提升制件的壁厚分布状态，在将第1道次的加工直径设置为dm+（D-dm）/4时制件的成形质量最好。根据有限元模拟实验，分析制件的壁厚分布曲线和平均壁厚值，拟合出扩孔两道次渐进成形圆孔翻边高度的表达式，并通过实体实验验证，实现了对两道次渐进成形外缘翻边高度的预测。

A two-pass incremental forming outer edge flanging path was designed and optimized by using the research method combining numerical simulation and physical experiment, and compared with the single-pass forming, it was applicable to a wider processing range. The research results show that the use of the outer edge flanging path with circular arc and straight line in two-pass incremental forming can process the flanging parts with larger blank diameters that cannot be formed in a single pass and improve the wall thickness distribution of workpiece, and the forming quality is the best when the processing diameter of the first pass is set to dm+(D-dm)/4. According to the finite element simulation experiment, the wall thickness distribution curve and the average wall thickness value of workpiece were analyzed, and the expression of the round hole flanging height for the two-pass incremental forming of reaming was fitted. Through the verification of physical experiments, the prediction of the outer edge flanging height in the two-pass incremental forming is realized.
