我厂应用华南工学院研制的喷水式熔化极电弧切割技术,成功地切割了上百件不锈钢的圆形工件。实践证明,这种方法具有操作简便、成本低廉、效率高、卫生条件好等优点,深受工人同志的欢迎。工件的规格是厚3～6毫米,直径为300～1600毫米。为提高效率,将二、三块叠起来切,效果也很好。切制设备,是将原有的MZ-1000(EA—1000)型自动焊机进行改装:将焊机的送丝控制电路由自动调节改为手动调节;将控制箱与送丝及割炬行走机构分离,以便操作。改装原理图见图1,改装后的送丝速度为0.74～2米/分,行车速度为0.073～1.6米/分。焊机由下
I plant the South China Institute of Technology developed by water-jet melting pole arc cutting technology, successfully cutting hundreds of stainless steel circular workpiece. Practice has proved that this method has the advantages of simple operation, low cost, high efficiency, good sanitary conditions, welcomed by the workers. The specifications of the workpiece is 3 to 6 mm thick and 300 to 1600 mm in diameter. In order to improve efficiency, will be two or three stacked up, the effect is also very good. Cutting equipment, is the original MZ-1000 (EA-1000) automatic welding machine modified: the welding wire feeding control circuit from automatic adjustment to manual adjustment; the control box and wire and torch walk Institutional separation for easy operation. Modified schematic diagram shown in Figure 1, modified wire feed rate of 0.74 ~ 2 m / min, driving speed of 0.073 to 1.6 m / min. Welder from the next
