针对目前热轧横切线中圆盘剪的切边量选取不合理现状,以废边为研究对象,将剪切力中的废边弯曲力作为负载,分析计算了其弯曲应力和扭转剪切应力,揭示了废边不发生弯曲变形和扭转变形所存在的最小废边宽度的限制条件,为合理确定圆盘剪的切边量提供了理论依据。
In view of the unreasonable selection of the trimming amount of the disc shears in the current hot-rolled cross-cutting line, the waste edge is taken as the research object, and the bending force in the shearing force is taken as the load. The bending stress and torsional shear stress The limit condition of the minimum width of the waste edge without bending and torsional deformation is revealed, which provides a theoretical basis for the reasonable determination of the amount of edge cutting.
