Abstract：

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.
