抄録

In sheet metal working, the accuracies of bending angle and flange length have a significant effect on product quality. Hence, it is necessary to accurately predict the springback and bend deduction of a sheet metal. The effect of punch track radius on the mechanism of L-bending was clarified by a 2D finite element method in this study. Because both springback and spring forward exist in L-bending, it is difficult to predict bending angle. Hence, firstly the validity of numerical analysis was confirmed by comparison with experimental results. Secondly, the effects of punch track radius on bending force, bending radius, bend deduction, springback and spring forward were elucidated. Finally, the new L-bending mechanism was clarified.
