伺服系统在连续式飞剪系统中的设计与应用

Design and Application of Servo System in the Continuous Flying Shears System

伺服系统采用先进的数学模型,精确计算飞剪剪切的各项控制参数,实现飞剪的自动剪切、碎断、定位和采样功能。该数学模型包括飞剪剪切长度计算模型与转辙器定位计算模型。应用结果表明,该数学模型能够在运行中获得良好的动态性能,将轧件的平均剪切误差控制在5 cm以内,提高了产品的成材率与产量。

In servo system, advanced mathematic model was adopted to accurately calculate each control parameter of flying shear, so that automatic cutting, cobbling, positioning and sampling functions of flying shears were achieved. Mathematical model included shearing cutting length calculation and switch pipe positioning calculation. Application results show that the control model can acquire to moving state performance goodly in the movement, and average cutting tolerance of roiled strip is controlled within 5 em, so that product output and economic benefits is improved.
