A study on springback of bending linear flow split profiles.
In: The International Deep Drawing Research Group (IDDRG), Linz, [Conference or Workshop Item]

Abstract

The bending of profiles made up of high strength materials involves high bending loads, high springback and possibility of geometrical defects. Profiles produced by linear flow splitting are made stronger due to the high plastic deformation applied by the process itself. The bending method proposed in this paper combines the linear flow splitting process with a bending operation. The aim of the research was to investigate the effect of superimposed stresses exerted by the linear flow splitting process on bending loads and springback of the profiles by using a finite element model. The latter was validated by means of experiments. The results show that the bending loads and the springback were reduced by increasing the superposition of stress applied by the linear flow splitting process. The reduction in the bending loads leads to a reduction in the cross-sectional distortion.
