提高双边剪剪切质量分析及研究

Analysis and Research on Improving the Shearing Quality of Double Side Trim Shear

针对双边剪剪切质量不理想，交刀台阶大的现状。通过对刀缝间隙，刀片平行度，夹送辊跑偏，刀片使用率及剪切工艺参数的分析和研究，判断出影响剪切质量的主要因素。并对其进行改进，得出了钢板高质量切边的最佳工艺参数，保证了钢板边部的剪切质量。

Because of the shearing quality of double side trim shear is not ideal and the status of large step between each two steps. Through analysis and study on blade parallelism, deviation of pinch roll , blade rating and the shear process parameters, the main factors affecting shearing quality can be found. By improvement, the best process parameters can be got to ensure the edge trimming quality of steel plate.
