Development of a closed loop control system for discharge parameters of electric spark deposition

  • 摘要: 为实现电火花沉积的自动化,研制了一种电火花沉积的放电参数闭环控制系统,能够实时采集沉积过程中的放电参数,基于放电脉冲平均电压与接触力呈反比的线性规律,通过调节进给电机和进给滑台控制工件与电极的接触力进行放电脉冲平均电压的闭环控制,实现了电极的自动进给调节.采用模块化技术设计了控制系统的模拟电路、数字控制电路和控制软件,缩短研制周期,使可靠性得到保证,便于升级和扩展.电火花沉积的试验结果表明,研制的放电参数闭环控制系统能够实现电极与工件的稳定接触,获得均匀致密的沉积层,便于实现电火花沉积的自动化操作,有利于电火花沉积技术的推广应用.
    Abstract: In order to realize the automation of electric spark deposition (ESD), a closed loop control system of discharge parameters for ESD was developed. Discharge parameters during deposition are collected in real time. Based on the linear law that the average discharge pulse voltage is inversely proportional to the contact force, the closed-loop control of the average discharge pulse voltage is achieved by the feed motor and the feed slide adjusting the contact force between the workpiece and the electrode, and thus the automatic feed adjustment of electrode is realized. The analog circuit, digital control circuit and control software of the control system are designed by modular technology, which can shorten the development period, ensure the reliability and facilitate the upgrade and expansion. The test results of ESD show that the developed closed loop control system of discharge parameters can realize the stable contact between electrode and workpiece and obtain uniform and dense deposition layer, which is convenient to realize the automatic operation of ESD and is conducive to the popularization and application of ESD technology.
