本文的第一部分介绍了直翻边的实验室实验，其中工艺参数，如模具肩部半径，凸模间隙，凸模圆角半径，垫力和材料性能的影响进行了讨论。第二部分总结了翻边的有限元预测，并将这些结果与一些实验数据进行了比较。此外，翻边与压印，以减少回弹已被研究和评估，更好地在翻边和卷边过程中的尺寸控制有限元。
Part 1 of this two-part paper presents the laboratory experiments on straight flanging, in which the influence of process variables, such as die shoulder radius, punch-die clearance, punch nose radius, pad force and material properties were discussed. This second part summarizes the FEM predictions for flanging and compares these results with some experimental data. Furthermore, flanging with coining to reduce springback has been investigated and evaluated by FEM for better dimensional control in flanging and hemming processes.
