摘要：

提出了一套完善且实用的精锻机专用控制系统研发方案，包括开发润滑系统以保护主机锻造箱和操作机夹头等关键部件，设计液压辅助系统为精锻机提供稳定的源动力。同时，基于精锻机高频旋转锻造原理规划了锤头锻打、夹头旋转和操作机进给等运动控制系统。在此基础上，采用工业控制计算机和4类多功能控制卡的控制模式对专用控制系统进行具体实现。以Python作为软件开发工具，利用多功能控制卡、PLC和中间继电器实现了稳定的软硬件通讯，很好地实现了对精锻机各子系统的高精度控制。研发了具有自主知识产权的精锻机专用数控系统，为精锻机的应用和继续改进奠定了基础。

A complete and practical research and development scheme for the special control system of precision forging press was proposed, including the development of a lubrication system to protect key components such as main engine forging box and manipulator chuck etc., and the design of a hydraulic auxiliary system to provide a stable source of power for precision forging press. Moreover, the motion control systems such as the forging of hammer head, the rotation of chuck and the feeding of manipulator were planned based on the principle of high-frequency rotary forging for the precision forging press. On this basis, the special control system was realized by the control mode of industrial computer and four multi-function control cards. Using Python as a software development tool, the multi-function control card, PLC and intermediate relays were used to realize the stable software and hardware communication and the high-precision control of each subsystem for the precision forging press. Thus, the special numerical control system for precision forging press with independent intellectual property rights was developed which lays the foundation of the application and continuous improvement of precision forging press.
