焊工在钢板上切割圆形工件时,往往不是两手端着割炬沿着用粉笔画的线条切割,就是将割嘴套在简易割规上,以钢板上打的冲眼为圆心,扶着割炬依照划规画出的圆形轮廓线进行切割。但是,不管采用哪种方法,切割质量都不够理想,难以获得垂直切口。根据生产实践经验,自制成功的磁力割圆规如下图所示。在该割圆规中,因标杆4的表面上有着长度公制刻度,中心套5底部与磁铁6
When welders cut circular workpieces on steel plates, it is often not the case that the torch is cut along the line drawn with chalk, that is, the cutting torch is set on the simple cutting rule, the red eye is hit on the steel plate, and the cutting torch is held Cut according to the circular outline drawn by the drawing. However, no matter which method is used, the quality of the cut is not ideal and it is difficult to obtain a vertical cut. According to the production of practical experience, self-made magnetic cutting rule as shown below. In the cutting rule, due to the surface of the rod 4 has a metric scale length, the bottom of the center sleeve 5 and the magnet 6
