Research on Galling Behavior in Square Cup Drawing of High Tensile Strength Steel
Based on the laboratory experiments, the drawing galling behavior in macro-scale is investigated in the square cup drawing of a high tensile strength steel SPFCS90 in semi-dry condition. When using the non-coated dies (cold alloy tool steel (SKD11,SLD) and austempered ductile irons (ADI)) in semi-dry, the macro-scale galling can clearly observed on die and drawn cup surface after a few drawing cycles. The galling on the die surface occurs at the bottom point of the boundary between the straight and corner edge, and grows upward with the drawing cycles. On the drawn cup, the galling starts at the top of the same boundary and grows downward. Simultaneously, the finite element method (FEM) with DEFORM-3D was used as a tool to simulate the square cup drawing process with respect to the drawing force distribution and volume change analysis, which gave us a rational interpretation of the drawing galling phenomena and illustrated the galling performance and seizing tumour theoretically.
