通过对V形弯曲回弹的讨论,建立一个V形弯曲回弹调节的试验模具模型。该模型的建立,旨在能够事先不需要计算就可以掌握该材料的回弹性能。该弯曲模具能够调节其弯曲角度的大小。试验时,先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,而后进行模具设计。V形弯曲回弹调节的试验模具可以很准确地确定弯曲回弹的回弹量,为V形弯曲模具的设计带来极大的方便。

V bending springback adjusting test model was set up by discussing the bending springback.The material springback performance could be mastered through setting up V bending springback 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 be determined by V bending springback adjusting test die.This makes it very convenient to design the V bending die.
