Description

CUTTER FOR MANUAL OXYGEN-FLUX CUTTING OF STAINLESS STEELS, IRON AND COLORS

The invention relates to the field of oxygen-flux cutting of materials that are difficult to cut, such as stainless steel, cast iron, non-ferrous metal alloys, concrete, etc.

Of the known cutters, the closest in combination of essential features and technical result achieved is a cutter containing a handle with V-shaped valves for combustible gas and oxygen with pipelines of combustible gas and oxygen connected to them, a head with a mouthpiece and a mixer of combustible gas and oxygen, with suitable pipelines of combustible gas of oxygen and cutting oxygen with a flow regulator located at the vertices of a regular triangle. (Utility Model Certificate of the Russian Federation No. 20051, class B23K 5/00, 20.10.2001), The disadvantage of this cutter is the inability to cut materials that are difficult to cut, such as stainless steel, cast iron, non-ferrous metal alloys, concrete, etc.

The objective of the utility model is to create a torch suitable for cutting any materials.

The specified technical result is achieved due to the fact

that the cutter for manual oxygen-flux cutting of metals contains a handle with V-shaped valves of combustible gas and oxygen with the pipelines of combustible gas and oxygen connected to them, a head with a mouthpiece and a mixer of combustible gas and oxygen, with suitable pipelines of combustible gas of oxygen and cutting oxygen with a flow regulator located at the vertices of a regular triangle, while, according to a utility model, the cutter is additionally equipped with accessories for supplying flux to the cutting zone. The presence of the specified additional equipment allows you to use a conventional oxygen cutter for cutting any materials. Additional equipment is easily attached to the cutter by means of clamps.

It is advisable that the equipment for supplying flux included a nozzle with a sleeve located on the head of the torch, and a pipeline with a valve and a nipple for supplying flux to the cutting zone. The presence of a nipple simplifies the connection of the flux supply hose, and the nozzle with a sleeve located on the torch head provides the flux to the cutting zone.

It is advisable that the flux supply pipe is located under the pipelines for the supply of combustible gas, oxygen and cutting oxygen and attached to them with clamps. This arrangement of the pipeline increases the usability of the torch and simplifies its mounting on the torch.

It is advisable that the flux supply pipe in the zop

bending was spabzhennym transitional spherical-shaped couplings. The presence of couplings simplifies the manufacture of the pipeline and provides smoother transitions in places of bending.

It is advisable that the nozzle with the sleeve formed a cavity for supplying flux.

It is advisable that the nozzle in the flux supply zone be provided with an annular groove and longitudinal grooves uniformly located on the outer surface of the nozzle from the annular groove to the nozzle cut and with a conical groove in the nozzle cut. The presence of a groove creates a flux supply chamber, and the grooves and a conical cut ensure uniform supply and focusing of the flux in the cutting zone.

The analysis of the prior art showed that the claimed combination of essential features set forth in the formula of the utility model is unknown. This allows us to conclude that it meets the criterion of novelty.

The essence of the utility model is illustrated in the drawing and description of the work.

 HO

Cutter includes conventional oxygen cutter 1 and accessories 6

for supplying a flux, including a nipple 2, a valve for shutting off and opening a supply of flux 3, connecting tubes 5, connecting couplings 7, a nozzle 8 with grooves 10 and an annular groove 11 and a sleeve 9. The torch operates as follows. After connecting the torch to the cylinders with flammable gas, oxygen and a flux source, opening the oxygen and combustible gas valves on the torch handle one by one, the torch size is adjusted at the outlet of the mouthpiece, the metal is heated, and then the cutting oxygen and flux are fed and the material is cut. At the end the cuts close alternately the flux supply valve, the cutting oxygen valve, the combustible gas valve and the oxygen valve. Based on the foregoing, we can conclude that the claimed cutter can be implemented in practice with the achievement of the claimed technical result, i.e. he meets the criterion

industrial applicability.
