摘　　要：针对回转支承整体淬火机床功能单一、控制系统开放性差、难以实现数据管理等问题,设计了以PLC为控制核心、HMI触摸屏为人机交互界面的淬火机床全自动控制系统。实现了整体淬火工序的时序与逻辑控制;通过触摸屏监测加工的动态过程,可对零件加工参数进行实时存取操作;系统中功率和淬冷时间等关键参数可依据用户的工艺需求设定,不仅解决了数据管理和系统开放性不足的问题,还提高了淬火效率和淬火稳定性,实现了整体淬火的自动化控制。To solve the problems such as single function, closed control system and poor data management for slewing bearing overall quenching machine, an automatic control system was designed, which was based on the core controller PLC and HMI touch screen working as the human-computer interaction interface. The time sequence and logic control for overall quenching procedure were realized and the real- time parts processing parameters were accessed since the touch screen monitors the dynamic process. The key parameters such as power and quenching time can be set according to the manufacturing requirements from the user. As a result, this system not only resolved the problems of poor parameter data management and the openness of system, but also improved the quenching efficiency and stability, and uhimately accomplished the automation control of the overall quenching process.
