【摘要】 К900钢轨交流闪光焊机是我国从前苏联(现乌克兰)巴顿焊接研究所引进的移动式连续闪光焊机,具有结构简单、维修方便、维护费用低的特点。由于历史原因,这些焊机都不具有脉动闪光焊工艺,难以焊接U75V这类焊接性较差的钢轨。针对原К900焊机的不足,对К900的控制系统进行改进,重新编制了PLC控制程序,增加了脉动焊接工艺;细化焊接过程,将焊接阶段由原来的五个阶段增加为八个阶段,可调参数由原来的13个增加为59个,使焊接工艺可调性更强,达到焊接U75V钢轨的要求。更多还原

【Abstract】 К 900 rail flash butt welding machine is a continuous flash butt welding machine which is imported from E.O.Paton Welding Institute of former Soviet Union(now Ukraine).It has the merits of Simple structure,easy maintenance and low maintenance costs.But because there is not the pulse flash butt welding craft,it is difficult to weld the rail U75V.Aiming at the lack of welding machine control system,this paper made the contributions as follows:re-designing of the PLC control procedures,and adding to the module of pulse process;subdividing the five original welding stag into eight stage and increasing adjustable parameters from the original 13 to 59 and overall debugging on welding machine so as to ensure the stability of control system.更多还原
