摘要
针对大型龙门刨床B2025目前存在的问题,对其电气控制系统进行全面的技术改造,增加铣削功能以适应各种加工要求。该控制系统以PLC为核心以及人机界面为控制界面,完成开关量逻辑控制、转速控制、工作台智能调节及人机界面交互;西门子直流调速器6RA80实现刨削控制系统改造;西门子变频器MM440实现铣削功能控制。通过改造,提高了系统的可靠性、稳定性,操作界面简单、友好,满足生产加工多元化要求。
Aiming at the existing problem of large-scale B2025 gantry plane, a comprehensive transformation is applied to its electricity control system, increasing the milling capabilities in order to adapt to the processing requirements.With Siemens programmable logic controller as the control core and human-machine interface as control interface, the switch logic control, rotational speed control, workbench intelligent regulation and human-machine interface are accomplished; and the Siemens 6RA80 DC speed governor is to achieve planing control system transformation; while the Siemens converter MM440 is to a-chieve milling functions.The result of reconstruction shows that it improves the reliability and stability of machine, and the op-eration interface is simple and user-friendly.The performance satisfies the requirements of production process.
