应用相关技术提高离合器式飞剪的剪切精度

Increasing the shearing precision of the clutch form flying scissors by means of relation technology

为提高离合器式飞剪的剪切精度 ,采用相关测速技术 ,对热轧线材的运行速度进行在线测量 ,并综合运用可编程序控制器及其高速计数模块 ,完成了系统控制软件的设计 ,使剪切误差控制在 +2 0 0mm以内 ,达到了国内先进水平 .

To improve the shearing precision of flying scissors, the correlative technigue is applied in the on-line measurement of the running speed of hot-rolling steel products, and through the comprehensive use of PLC and its high-speed counting module, the system control saftware has bcen designed, so as to confine shearing error with in +200 mm which is an advanced technological standard in China.
