Compasses for the manufacture of round, complex asymmetric PARTS CUTTING flanges, end caps made of steel sheets and pipes in any position BY GAS CUTTING

摘要

The invention relates to a welding production. The compass comprises a metric ruler and bears markings, which is fastened gas cutting machine with adjustable angle cutter (or core). To zero line is welded to the cylinder head mounting the cutter. On the line of the required length is welded a bracket for mounting the cutter pen. To the free end of the line can be attached to the continuation of the line by means of a hinge fixing. On line slider mounted, wherein the support portion is fixed with two-sided punch. The slider is moved along the ruler and recorded. The technical result of the invention is to increase productivity of manufacturing round, asymmetric complex parts, cutting flanges, plugs made of sheet steel and pipes of any size by gas cutting. The compass provides the required manufacturing precision of parts and increases the manufacturability of their production.
