摘　　要：建立了启停式曲柄飞剪的剪切性能和加速性能校核的计算模型,并利用所建模型对某热轧型材生产线上的飞剪进行了计算与分析。此计算分析过程主要考虑飞剪在剪切过程中所释放的能量能否满足剪切功要求以及飞剪电机能否在允许的启动角内使剪刃加速到所需速度。分析结果表明:可将所建立的启停式曲柄飞剪计算模型应用于飞剪性能检验和同类飞剪的优化设计。In this paper, the calculation model of shearing and accelerating performance parameters for crank flying shear is introduced. With this method, the shear in the production of section material is calculated and analyzed. In this process, whether the drive system can release enough kinetic energy and whether the motor can be started in allowable angle are considered. The result indicates that the calculation model is feasible for determining performance, and designing this kind of flying shear.
