摘要:

高速轧辊磨床是冶金生产领域一种不可或缺的重要设备,它是基于高精度和稳定可靠的电气控制系统来实现对磨削过程的准确控制。针对一种砂轮线速度在80 m/s以上的高速轧辊磨床,以FX3UPLC作为控制器,采用与PLC(programmable logic controller,可编程逻辑控制器)标准配套的A/D及D/A特殊功能模块,组成PLC模拟量控制系统,设计了基于FX3UPLC和变频器控制的高速精密轧辊磨头主轴驱动控制系统。介绍了高速精密轧辊磨头运行时的控制要求及磨头主轴电机变频调速控制系统的组成、控制方案及信号处理方法,设计了硬件电路、电机速度控制梯形图及系统通信程序。利用组态王软件开发了上位机监控界面,通过上位机组态界面输入框设定电机转速,加入模拟量编码器作为主轴电机转速反馈传感器,引入PID速度闭环控制系统,使得电机能够在给定转速下稳定运行。系统采用PLC对模拟量信号进行实时采集,经数模计算和反馈,实现轧辊磨头主轴系统各过程变量的实时监测和主轴电机输出转速的在线调整。该系统运行稳定,具有较好的抗干扰性能,保证了高速精密轧辊磨头连续可靠、安全高效的运行。

Abstract:

High-speed roll grinder, which is based on high precision and stabilization electrical control system, is an indispensable equipment in steel production fields to achieve accurate control of the grinding process. Aiming at a kind of high-speed roll grinder whose grinding speed was more than 80 m/s, with the FX3UPLC as controller, the PLC (programmable logic controller) analog control unit was formed by using the supporting standard A/D and D/A special function module of PLC, and the spindle drive control system of high-speed precision roll grinding head was designed based on FX3UPLC and frequency converter. The requirement of high-speed precision roll grinding head on its electrical control system was described, and the variable frequency speed-adjusting control system was introduced with the constitution, controlling scheme and signal-disposal methods. The hardware circuit, motor speed control trapezoid chart and analog control system communication program were designed. In addition, by using Kingview software, the PC monitor screen was developed, and the motor speed was set up by the input box of PC software, and the analog encoder was taken as the feedback sensor of output speed of the spindle motor. At the same time, the PID speed closed-loop control system was added to make spindle motor operate smoothly by the given speed. The PLC was adopted to carry on the on-site collection to the analog signal through the mathematical model calculation and signal feedback of the operating environment. Finally, the entire control system realized the on-line adjustment of the spindle motor output speed and the real-time detection of the process variables and ran steadily, which had good anti-interference performance and ensured the continuous and reliable, safe and efficient operation of the high-speed precision roll grinding head.

Key words: high-speed roll grinder    frequency converter    PLC    on-line monitoring
