摘　　要：电镦是现行气门生产重要工序之一,电镦机与电镦技术已经成为气门生产中的关键。文章描述了嵌入式智能电镦机的设计,基于μC/OS-II操作系统设计的控制软件,实现了电镦加工自动化,设计了方便的人机操作界面。电镦控制系统是非线性时滞系统,采用模糊自整定PID控制策略优化了电镦过程中的电流、压力、速度的控制。经生产现场实践证明,嵌入式电镦机大大提高气门生产的自动化程度,有效促进了气门生产量的增长。Upsetting is currently a very important working procedure. Upsetting machine and the upsetting technology had been the key role in the valve production. Embedded intelligent upsetting machine is based on μC/OS-Ⅱ real-time operating system. It processes automatically and conveniently with less worker and less training. The electric upsetting control system is a Nonlinear Time-Delay Systems, so Fuzzy-PID suits to the upsetting process. It can be optimized parameter such as current, press and velocity. Practice has proved that the embedded intelligent upsetting machine makes it higher in automation and is increasing productivity.
