圆盘剪侧间隙变化是发生剪切不正常的重要原因。通过分析圆盘剪侧间隙变化,查找可能影响侧间隙变化的相关因素。同时通过计算刀轴热膨胀量,分析上下刀轴结构,确定上下刀轴热膨胀方向不一致是造成侧间隙变化的根本原因。通过采取改进措施,确保上下刀轴同方向膨胀,消除了侧间隙的变化,圆盘剪能够稳定生产,确保机组顺行生产。
Disc shears side gap change is an important reason for the occurrence of shear is not normal. By analyzing the change of disc shear side clearance, find out the relevant factors that may affect the side gap change. At the same time, by calculating the amount of thermal expansion of the cutter shaft and analyzing the structure of the upper and lower cutter shafts, it is determined that the direction of thermal expansion of the upper and lower cutter shafts is inconsistent, which is the fundamental reason for the side clearance change. Through the improvement measures to ensure that the upper and lower knife shaft in the same direction of expansion, eliminating the side of the gap changes, disc shears to stabilize the production, to ensure that the unit forward production.
