微处理技术引入电阻焊控制,使电阻焊控制器产生了质的改进。本文介绍的μcw—100点、凸、缝焊控制电脑是一台采用Z—80系列微机器件研制成功的点、凸、缝焊专用电脑。焊接工艺参数直接以十进数从键盘输入,无须使用计算机语言,也无须藉助编码手册,以代码表示焊接方式和工艺参数。本文阐述了一种独特的恒电流监控的原理和方法,通过试验数据显示了μcw—100对于网络电压变化、二次回路阻抗变化和工件厚度变化的极好的适应性,网络电压变化±20％时焊接电流变化不超过3％。本控制器已在汽车生产中应用,已焊零件10万件以上。
The introduction of micro-technology resistance welding control, resistance welding controller produced a qualitative improvement. This article describes the μcw-100 points, convex, seam welding control computer is a use of Z-80 series of computer devices successfully developed point, convex, seam welding computer. Welding process parameters directly from the keyboard input in decimal, without the use of computer language, nor with the coding manual, the code that welding methods and process parameters. This paper describes a unique principle and method of constant current monitoring, the test data shows the μcw-100 for network voltage changes, secondary circuit impedance changes and workpiece thickness changes excellent flexibility, the network voltage changes ± 20% When the welding current does not change more than 3%. The controller has been applied in automobile production, welding parts 100,000 or more.
