| 摘 要： | 回弹是影响钣金成形质量的主要因素之一，对钣金折弯回弹的准确预测和有效控制是提高折弯成形精度的关键.在分析弯曲成形及弹复过程的理论解析基础上，开发一种应用于高精度V形自由弯曲成形的折弯系统，基于单向应变和小变形假设，建立折弯成形及回弹的理论模型，利用成形过程中测得的折弯参数计算得到材料的性能参数值，进而确定最终的折弯深度.通过计算结果与实验结果的对比，验证了该方法的可行性与有效性，为板料折弯成形的回弹控制提供了一种有效途径.

| Abstract: | The springback is one of main factors influencing the forming quality of sheet metal,and the accurate prediction and efficient control for the bending springback of sheet metal are the key to improve the precision of bending forming.On the basis of theoretical analysis on both bending forming and springback processes,a bending system applied to free V-bending forming with high precision was developed.Based on the unidirectional strain and small deformation hypothesis,a theoretical model for bending forming ... |
