埋件钢筋热镦机自动化控制系统的设计

Design of automatic control system of hot upsetting machine for embedded steel bars

针对埋件钢筋热镦机在不确定性和噪声干扰下的稳定运行需求,设计了一种自动化控制系统。该系统通过位置与温度传感器采集实时运行状态数据,利用微处理器和现场可编程门阵列实现数据的预处理,并结合模糊PID控制算法计算出自动化控制量。实验结果表明,该系统能有效控制加热温度和钢筋位置,使二者迅速达到预设值。在噪声干扰条件下,系统仍能保持顶镦杆速度和砧子速度的稳定,并实现了顶镦杆速度和砧子速度不同程度的精度提升,显著提高了埋件钢筋的加工质量。

An automated control system has been designed to meet the stable operation requirements of embedded steel bar hot upsetting machines under uncertainty and noise interference.The system collects real⁃time operating status data through position and temperature sensors,preprocesses the data using microprocessors and field programmable gate arrays,and combines fuzzy PID control algorithm to calculate the automation control quantity.The experiment shows that the system can effectively control the heating temperature and the position of the steel bars,enabling them to quickly reach the preset values.Under the condition of noise interference,the system can still maintain the stability and achieved varying degrees of improvement in the speed of the top heading rod speed and anvil speed,significantly improving the processing quality of embedded steel bars.
