线性分流能够从金属板生产分叉型材。包括在合作研究中心(SFB)666的新辊轧成形程序使用钝角分裂辊和支撑辊,以增加表面的带边缘。变形区中的高静水应力导致高强度钢ZStE 500的可成形性提高。作为该工艺的结果,凸缘部分由超细晶粒显微结构(UFG)组成。所生产的零件的特点是增加刚度和高表面硬度。新结构对成形性有广泛的影响。本文提出的研究讨论了进一步加工的法兰从线性分流的轮廓。为此,进行了三点弯曲试验和辊弯成形试验。有限元分析,以表征损伤,以及成立。
Linear flow splitting enables the production of bifurcated profiles out of sheet metal. Included in the Collaborative Research Centre (SFB) 666 the new roll forming procedure uses obtuse angled splitting rolls and supporting rolls to increase the surface of the band edge. High hydrostatic stresses in the deformed zone lead to an elevated formability of the high strength steel ZStE 500. As a result of the process, the flanges consist partially of an UltraFine-Grain microstructure (UFG). Produced parts are characterized by increased stiffness and high surface hardness. The new structure influences the formability in an extensive way. The investigations presented in this paper discuss the further processing of the flanges from linear flow split profiles. Therefore three point bending tests and roll forming experiments are carried out. A finite element analysis to characterize the damage is set up as well.
