摘　　要：针对铝合金锻造过程中存在的产品质量不稳定、生产效率低等问题,以汽车铝合金转向节为研究对象,进行了自动锻造生产线及其控制系统的设计。根据铝合金转向节的锻造工艺,规划了铝合金转向节生产线的设备构成和整体布局,分析了各工序主要设备的动作流程。设计了基于PFOFINET总线协议的生产线自动控制硬件系统和基于PLC的软件系统,提出了基于PLC的结构化程序框架,分析了铝合金转向节生产线的动作控制逻辑,解决了自动锻造生产线程序逻辑不清、命令冗长和故障难以排查的问题,提高了编程效率。生产试验表明:该生产线设备布局合理,可视化控制界面操作便捷,生产节拍达到每件22 s,设备运行安全稳定,生产线故障率低,产品质量稳定。In view of the problems of unstable product quality and low production efficiency in aluminum alloy forging process,for automo-bile aluminum alloy steering knuckle,the automatic forging production line and its control system were designed.Then,based on the forg-ing process of aluminum alloy steering knuckle,the equipment composition and overall layout of aluminum alloy steering knuckle produc-tion line were planned,and the action flow of the main equipment in each process was analyzed.Furthermore,the automatic control hard-ware system of the production line based on PFOFINET bus protocol and the software system based on PLC were designed,the structured program framework based on PLC was proposed,and the action control logic of the aluminum alloy steering knuckle production line was analyzed to solve the problems of unclear program logic,lengthy command and difficult troubleshooting for the automatic forging production line and improve the programming efficiency.The production tests show that the equipment layout of production line is reasonable,the vis-ual control interface is easy to operate,the production cycle reaches 22 s per piece,the equipment operates safely and stably,the failure rate of production line is low,and the product quality is stable.
