生产中,经常碰到钢板上气割各种大小不一的圆料。为了方便操作,提高质量,我们做了一个简易工具(如图)。使用时,先用圆规在钢板(工件)上划一个定心圆,定心圆的直径就是磁铁座1的直径。然后使磁铁座按定心圆定位,把整个工具通过磁铁座吸在钢板上。再利用尺杆2上的尺寸刻度,按所需气割圆料直径调整插入割嘴套 Production, often encountered on the steel gas cutting various sizes of round material. In order to facilitate the operation, improve quality, we made a simple tool (pictured). When used, first with a compass on the plate (workpiece) draw a centering circle, the diameter of the centering circle is the diameter of the magnet seat 1. Then make the magnet seat centering circle positioning, the entire tool through the magnet seat sucked in the steel. Re-use the scale bar on the scale 2, according to the required diameter cut gas cutting into the cutting sleeve
