Simulation analysis and bending die design of supporting frame

FEM analysis software of DYNAFORM was used to simulate the bending form for the support.The result showed that serious thinning was found in one die forming,and the distribution of stress and thickness of forming in two sets of dies are better than those in one die forming.So the bending forming in two sets of dies for support was determined.At the same time,the progressive bending die was designed.Two sets of bending dies for the support were fixed on one die carrier,so bending forming for the support was finished in one running distance.Then,the disadvantages of forming in one operation were avoided,and the low efficiency problem was also solved with single process.
