摘要
飞剪主要用来剪切定尺、切头、切尾、切取试样以及处理事故等，通常是安装在连续式轧机的轧制线上和连续式独立加工机组的作业线上。飞剪机是在轧件运行过中进行剪切，因而飞剪的结构、调整及控制比一般的剪切机要复杂，对设计和制造的要求也高。
本设计介绍了飞剪机特别是切头飞剪机在国内外的发展现状，同时提出了今后的发展趋势。还详细介绍了飞剪机的工作原理，以及转鼓式切头飞剪机的本体结构的详细设计。由于设计要求是在运动的过程中将轧件进行剪切，对设计制造的要求很高，所以本设计经过了详细的设计,从电动机的选择、减速器传动比的分配，到飞剪机转鼓部分的设计都进行了严谨的计算。对主要零部件进行了校核，保证了该飞剪机在轧钢生产线工作效率的最大化，工作安全可靠。

Abstract
Flying shear is mainly used for shearing and cutting head, tail, harvesting specimens, accidents treatment and so on, which usually installed in continuous rolling mill of rolling production line and continuous independent processing unit production line. Flying shear machine is to shear in the process of running, therefore, the structure, adjustment and control of flying shear with high requirements of design and manufacture are more complex than general shear.
This paper introduces the design of the flying shear machine, especially the present development situation of head cutting flying shear machine at home and abroad , which puts forward the future development trend. Also this paper introduces the flying shear machine working principle in detail and the detailed design of main structure of drum type cutting head flying shear machine. The design requirements is to be rolling shear in the movement process ,which is high demand for the design and manufacture. So this design proceeded detailed design and strict calculation from the choice of motor, reducer transmission ratio distribution to the design of flying shear machine drum part. In order to ensure the reliability of this machine in the usage in the future, this design check main parts and ensure the flying shear machine work efficiency maximization in the steel rolling production line , and also work safety and reliability.
Key words: flying shear, rolling mill, cutting head flying shear, development trend, design and calculation
