针对目前中厚板定尺剪在定尺送料过程中存在的精度和效率低下等问题,提出一种新的动态误差参数补偿的控制模型,充分利用夹送辊驱动装置的控制回路作为该控制模型的一部分,重点解决了控制模型工艺设置,实现方法及动态误差参数补偿等问题。实际应用结果表明钢板定尺长度L=6~14mm,厚度h=25~40mm,v=1~2m/s时,送板精度小于3mm。 Aiming at the problems such as the accuracy and inefficiency of the current plate sizing and cutting in constant length feeding, a new control model of dynamic error compensation is proposed. The control loop of the pinch roller drive is fully used as the control model Part of the focus on solving the control model process settings, methods and dynamic error compensation parameters and other issues. The practical application results show that when the length of steel plate is L = 6 ~ 14mm and the thickness is h = 25 ~ 40mm, the accuracy of the feeding plate is less than 3mm when v = 1-2m / s.
