横切线模式飞剪控制策略研究

Cutting Principle and Control Process of Modeling Shear in Cross Cut Shearing Line

分析了横切线模式飞剪的机械结构和运动形式,对其控制系统进行了设计。针对剪切过程速度快、精度高的特点,采用了基于卡尔曼滤波器的APC系统和基于神经网络的飞剪精度补偿。调试和生产运行表明,整个系统具有控制精度高、运行稳定、操作简单和维护方便等特点,满足生产高质量横切板的要求。

Mechanism structure and motion form of a die set shear in cross cut shearing line was analyzed,and itscontrol system was designed. According to high speed and high precision demands during cutting process,theautomatic position control（APC）system based on Kalman filter and the compensation of cutting precision based onneural network was adopted. Site debugging and production operation indicate that whole system has characteristics ofgood control precision,stable running,easy operation and easy maintenance,and it satisfies the demands of highquality cross cut plate.
