    摘要:

    针对高速钢轧辊材质的修复问题,展开高速钢轧辊材质电解磨削装置控制系统研发工作。基于普通外圆磨床的机床,以S7200 SMART系列PLC为控制器对阴极进给系统、电解液供液系统和加工系统进行控制。其次,展开高速钢轧辊材质电解磨削装置控制系统的硬件、软件以及人机交互设计,该控制系统具有自动对刀、故障检测等模块化功能。再者,对加工间隙控制提出了一种带修正因子的模糊控制器-PI双模控制方法,建立MATLAB/Simulink仿真模型,其结果表明该控制方法效果理想,鲁棒性强,可整定控制器增益参数,并将该算法编程于PLC中,最终可实现加工间隙控制过程稳态误差小、超调小、响应快、稳定性好。最后,展开预实验,探究了加工间隙以及温度对加工电流的关系,结果表明加工电流随加工间隙的增加而减小,随温度的升高而增加。

    Abstract:

    Aiming at the problem of repairing high-speed steel roll material, the control system of electrolytic grinding device for high-speed steel roll material was developed. Based on the machine tool of ordinary cylindrical grinder, S7200 SMART series PLC was used as the controller to control the cathode feed system, electrolyte supply system and processing system. The hardware, software and human-computer interaction design of the control system of electrolytic grinding device for high-speed steel roll material were carried out. The control system has modular functions such as automatic tool setting, fault detection and so on. A fuzzy controller PI dual-mode control method with correction factor was proposed for machining gap control, and the MATLAB/Simulink simulation model was established. The results show that the control method has ideal effect, strong robustness and it can adjust the controller gain parameters. The algorithm was programmed into PLC, the machining gap control process with small steady-state error, small overshoot, fast response, and good stability were realized. The pre experiment was carried out to explore the relationship between machining gap and temperature on machining current. The results show that the machining current decreases with the increase of machining gap and increases with the increase of temperature.
