| Abstract Scope |
Press forming of automotive frame parts which bent in the height direction with high strength steel sheet suffers from fracture and wrinkle caused by bending deformation.We has succeeded in developing new cold press forming technique with a process of two steps: first step for inducing in-plane shear deformation and second step for shaping into the bent part. The shear deformation in the first step was obtained by draw forming in unconventional press direction and had effect of suppressing the bending deformation. Relationship between the bent angle of the part and the shear deformation was clarified by experiments of small simplified model. When induced in-plane shear deformation increased, the part which had higher bent angle could be formed. The efficacy of the developed technique was confirmed by experimental trials using a real-size model of a front side member rear with 1180 MPa grade ultra-high strength steel sheet. |
