摘要：

为了提高旧型号的辊锻机机械手的运行精度和工作效率，本次改造将机械手纵向运动的液压驱动方式更改为变频调速驱动方式。突出介绍了改造中所用变频系统的组成与功能特点。在硬件设计中需要注意，在搭建系统时要保持变频器信号的稳定性与消除对周边信号的干扰等；在软件设计中，给出了几个重要参数的含义，并且编写了PLC梯形图。整个系统改造后，实际运行流畅，并且通过负载测试，变频系统元器件参数正常。通过本次改造可以得出：变频系统不仅能简化控制系统的硬件构造，并且还提高了设备的运行精度，减少了维护成本。改造后的系统使机械手运行更高效，也满足设备在当前自动化控制中控制灵活、可扩展等的需求。

In order to improve the operating accuracy and efficiency of the old roll forging machine manipulator, the hydraulic driving mode of the longitudinal movement for manipulator was changed to the frequency conversion speed control driving mode, and the composition and functional characteristics of frequency conversion system used in modification were highlighted. Then, in the hardware design, it was necessary to pay attention to maintain the stability of converter signal and eliminate interference to the surrounding signals when the system was built, and in the software design, the meanings of several important parameters were given and the PLC ladder diagram was written. After the modification of the whole system, the actual operation was smooth, the load test was passed, and the component parameters of frequency conversion system were normal. This modification shows that the frequency conversion system not only simplifies its hardware construction, but also improves the operating accuracy of equipment and reduces the maintenance cost. Thus, the modified system makes the manipulator move more efficiently and meets the needs of equipment to be flexible and scalable in the current automation control.
