摘    要：介绍了唐钢冷轧厂的三菱NMW-C1375F型闪光焊机控制系统的组成及其控制过程。该系统采用三菱Q3ACPU PLC和CC-Link现场总线技术。在连续闪光阶段通过控制顶锻缸的位置实现了对闪光曲线的控制。在焊后处理阶段根据板材的厚度调节刮削刀的参数实现对刮削的控制,从而得到高质量的焊头。该系统实现了焊接过程的全自动控制和故障处理功能。

Abstract: Composition and control process of control system for Mitsubishi NMW-C1375F type flash butt welder in Cold Rolling Mill of TISCO are introduced.Q3A CPU PLC and CC-Link fieldbus technology were adopted in the control system.Through location control of upset cylinder,flash curve can be controlled in consecutive flash stage.In order to get high quality welding head,parameters of trimmer can be adjusted according to thickness of strip to achieve scraping control.After the system was put into application,full automatic control and fault treatment function of welding process were realized.
