摘　　要：通过对U形弯曲回弹的讨论,建立一个U形弯曲回弹正弦调节的试验模具模型。该模型的建立,旨在不需要事先计算就能够掌握材料的回弹性能。试验时在能够进行弯曲回弹调节的模具上按照有关的回弹数据进行调节试验,确定材料的回弹值,然后再进行模具设计。这样可以大大减少模具设计后的试模和修模工作量,为模具设计者带来了极大的方便。U bending springback sine adjusting test model was set up by discussing the bending springback. The springback of material could be mastered through the set up of U bending springback sine adjusting test model without prior calculation. The bending angle could be adjusted by die itself. In the experiment, the springback value could be adjusted through the test model when it was tested and the material springback value could be made sure. Finally, the die was designed accurately. The bending springback capacity could determined by U bending springhack adjusting test die. This makes it very convenient to design the U bending die.
