摘    要：飞剪是钢铁生产企业连续轧制生产线上的重要设备,其结构设计、控制与调整很复杂,其工作性能与连续轧制生产线的生产效率密切相关.作者分析了IHI摆式飞剪结构及传动原理,建立了剪切机构运动学数学模型;应用Matlab程序设计语言强大的数学计算和图形处理功能,将剪切机构运动学模型程序化、数值可视化,得出飞剪上、下剪刃的运动轨迹曲线、速度曲线以及剪刃开口度变化曲线,这对了解飞剪运动全过程和定量分析剪切机构工作性能,合理建立剪切机构优化设计模型具有参考价值.

Abstract: Flying shearing is a important device in continuous rolling product line, it has complex control system and regulate system.The paper analysises the structure and composition of IHI swing-flying shearing, then establishes kinematics model for shearing framework, and compiles analyses program with powerful MatLab language in mathematic and graphics. Movement track, velocity curve and openmouthed size curve for edge of shearing-knife are obtained. The results have important meaning in understanding shearing performance and optimize designing.
