摘要
在我国的连续式轧钢机组中,飞剪机的参数设计直接影响剪切质量。本文对引进的双曲柄联合式飞剪机设备进行设计改进,对最大的剪切力计算过程进行分析并确定了最大剪切力的位置,对采用梯形钢板焊接而成的上下剪刀装配结构进行改进设计,并对该飞剪机的剪刃速度、曲柄转速、剪切冲击力和剪切功进行分析计算。分析计算结果对于提高飞剪剪切质量、定量分析剪切机构的工作性能和设计同类飞剪具有一定的参考价值。该改进后的设备已成功应用于生产中。
The mechanism of flying shearing equipment concerns the shearing quality of steel in continue mode rolling mill in China. The kinematics model of the shear mechanism for the double-crank and connected fly-shear was estab- lished. The position of the maximum shear cutting angle was identified and the calculation process of the maximum shear force was researched. The pair of scissors with trapezoidal steel plate welded assembly structure was improved and the speed of shear blades and cranks, impact shear force and shear power were calculated and analyzed. The results are positive to improve the shearing quality, to analyze the function of the shear mechanism and to design the same kind fly-shear. The improved device has been successfully applied to production.
