nozzle to the MPK WELDING TORCH in 23 to 9/16

The utility model relates to the field of welding, in particular, to structural steel arc welding for two-gas gas protection of a welded bath 1FI arc welding with a consumable electrode.

Known nozzle for a welding torch containing associated with the supply path of sludge gases, such as carbon dioxide and argon, a hollow cylinder pfpiecKffii housing with an exit part {see: 1. N. Zhozhilov N.M. Fundamentals of metallurgy gas arc welding. M. Engineering, 1979; 2. Nikiforov G.D. et al. Technology and equipment for fusion welding. M., Mechanical Engineering, 3. Altshul A.D. and others. Hydraulics and "erod {shagkiosa {basics mech" ENosh fluid) Textbook for High Schools, ed. 2, revised and supplemented. M., Stroyizdat, 1975).

Known nozzle designs are bulky, difficult to manufacture, and more durable.

The task is to create a nozzle design with an outlet part., Providing two-jet gas protection for the weld pool using only one gas (carbon dioxide, argon, etc.).

The solution to this problem is achieved by the fact that the nozzle of the welding torch, containing a hollow pipe no. Kksh connected to the shielding gas supply path with the output part, is equipped with an insert in the form of steps, 11 NN of the chat sleeve, with a larger stage installed in the output part of the housing, and in taller Tynesti to a small discharge located uniformly around the circumference of the hole of a round gofofil and / or in the form of grooves, while the central hole of the sleeve is cylindrical, and the outer surface of the smaller step is conical, narrowed eysya in TOpofsy exit or to the side walls of the transition.

The inventive device is characterized by the presence of the following natural distinguishing features:

-a) the stitch is equipped with an insert in the form of a stepped sleeve;

b) the sleeve is installed in a larger step in the output part of the housing;

c) in the wall of the transition from the larger to the smallest step the bushings are arranged uniformly around the circumference of the holes;

d) the peshral hole of the sleeve is cylindrical;

d) the outer surface of the lower stage is made conical, tapering towards the exit;

€) the outer surface of the step is made conical, tapering towards the transition wall.

The studies on the patent and scientific literature made it possible to reveal a number of technical solutions of a similar nature, however, there are no signs of it, therefore, the claimed device meets the patentability criteria of the utility model, and numerous experimental studies have shown operability // 4 f

The proposed nozzle design, which is small in size, is prepared and has TexHOflOfii HO; it has an equally low cost.

The essence of the application is illustrated by drawings, where in FIG. 1 shows a general view of the nozzle to the welding torch with the insert removed, in FIG. 2 - the second version of the insert; in FIG. 3 - the shape of the gas stream when performing the insert ifepeoMy option; on F1g. 4 - the same, but the second option.

The nozzle to the cooking torch contains a hollow cylindrical body 1 connected to the shielding gas supply path (to hell, not shown) 1 with an output part 2, into which an insert in the form of a β-step sleeve is installed at a higher stage 3; in “tyns 4 pfohhods from the greater step 3 to the lesser 5, holes 6 are arranged uniformly around the circumference, having a round profile and / or in the form of grooves. The outer surface 7 of the smaller stage 5 is made conical, tapering towards the exit {Fig. 1 - the first option) or in the direction of the wall 4 of the transition {Fig. 2 - second option). The inner surface of the Central axial hole 8 is full. cyl-indriceoc.

After installation, the insert 2 of the Korgus 1 insert inserts a protective gas supply, which, passing through the holes of the insert, forms two gas flows (outer ring and inner solid) surrounding the weld pool (not shown).

The welding was done in various modes using carbon dioxide, while a steady gas flow was observed (see Figs. 3 and 4), which ensures reliable

kind of air.
