我厂生产的WY60液压挖掘机工作装置和转台等部件和WL601轮胎式挖掘机转台、W604履带式挖掘机水平轴等部件,应用粗丝CO_2半自动焊接(采用天津电焊机厂生产的NBC1-500型焊机,φ1.6mm焊丝),取得了较好的效果并已投入成批生产。一、焊机的改装NBC1-500型焊机系利用磁放大器控制和调节电孤电压,通过可控硅调速电机调节送丝速度和焊接电流。调节灵敏可靠,但送丝和送气系统还存在一些问题,使用前须作必要的改装。1.送丝软管和电缆线并在一起,软管既
The WY60 hydraulic excavator working device and turntable parts produced by our factory and the WL601 wheeled excavator turntable and W604 crawler excavator horizontal shaft and other components are applied with coarse CO_2 semi-automatic welding (using NBC1-500 type produced by Tianjin Electric Welding Machine Factory. Welding machine, φ1.6mm wire), has achieved good results and has been put into batch production. First, the modification of the welder NBC1-500 welder uses a magnetic amplifier to control and adjust the solitary voltage, and regulates the wire feeding speed and welding current through a thyristor speed-regulating motor. The adjustment is sensitive and reliable, but there are still some problems with the wire feeding and air supply system, and necessary modifications must be made before use. 1.
