Abstract
The utility model relates to an oxyhydrogen flame welding burner which is especially used for oxyhydrogen welding. The utility model is composed of a core sleeve with a central hole through passage and an out sleeve covering outside the core sleeve. At least two gas distributary passages are formed, and the speed of the gas can be lowered, thus the requirement for oxyhydrogen gas burning speed is satisfied, and the sufficient combustion can be realized. The heat quantity is concentrated, the flame area can be enlarged, so thick material can be welded. The utility model not only is suitable for the burning forming of glass and quartz products, and the welding of non-ferrous metal, but also is suitable for welding ferrous metal. The utility model has the advantages of simple structure, easy production, convenient operation and multiple purposes.
Description
The utility model belongs to the class of jobs gas welding unit, particularly is exclusively used in the oxygen-hydrogen welding torch-tip.
Along with people are more and more high to energy-conservation and requirement on environmental protection; with water is the energy and deep the carrying out of research that carries out energy conversion; and more and more come into one's own; simultaneously; with the hydrogen-oxygen source is that the welding equipment of the energy has also been asked thing; if adopt the welding of this kind equipment; capable of reducing energy consumption 70%～80%; saved traditional oxy-acetylene gas welding manufacturing again; a series of problems such as the power consumption of transportation calcium carbide and environmental pollution; nor produce the carbon dioxide pollution environment; but; so far be not useful on the oxyhydrogen welding welding torch as yet; its nozzle particularly; can only replace with common gas torch and nozzle during welding; because this nozzle has only a centre bore straight channel; air-flow velocity is fast; and the burning velocity of oxyhydrogen flame is slow; have only 2 meter per seconds, the oxy-acetylene burning velocity can reach 7 meter per seconds, thus oxyhydrogen at flame in the distance of jet expansion; can not burn fully; nozzle is near by the face of weld time, and a large amount of unburned oxygen make the strong oxidation of face of weld, again because the flame envelope temperature is not high; nozzle causes heating surface to reduce with regard to the more close working face of needs during welding; even have only the part to be melted by the face of weld, and having a strong impact on welding process, especially can not weld ferrous metal at all.
The purpose of this utility model is: be used for deficiency on the oxygen-hydrogen welding technical pattern at the oxy-acetylene welding nozzle, design a kind of nozzle that is exclusively used in oxygen-hydrogen welding first, under the condition that does not change existing welding torch, only change its nozzle arrangements, become an original only centre bore straight channel and be porous channel, air velocity is reduced, full combustion of gas, the drop of the flame, thermal field increases, and realizes the welding of oxyhydrogen flame to ferrous metal.
The purpose of this utility model is achieved in that oxyhydrogen flame welding torch nozzle comprises joint screw thread that links to each other with welding torch and the nozzle body of being with the centre bore straight channel, it is characterized in that: nozzle is made of the core retainer plate and the outer overcoat of its core retainer plate of socket of the centre bore straight channel of the band central through hole in centre, form an endless belt cavity passage around core retainer plate between core retainer plate and the overcoat, gas by hole, the through hole shunt centre straight channel on the core retainer plate wall sprays in the endless belt passage, forms at least two passages.The gas outlet end of nozzle has contraction mouth, also can around core retainer plate some dispersion passages be set at the port of export of overcoat, makes the shunting gas of endless belt through hole shunt ejection once more.
The utility model has the advantages that: solved the oxygen-hydrogen welding nozzle first, reached of the requirement of oxyhydrogen burning velocity to welding, successfully realized the welding of oxyhydrogen flame to ferrous metal, accomplished that again a welding torch uses more, as long as change oxy-acetylene welding torch nozzle with the utility model nozzle, just can realize the oxyhydrogen flame welding, this orifice gas is owing to going out from a plurality of corridor diversions, gas flow rate reduces, this has just adapted to the oxyhydrogen requirement of burning at a slow speed, make hydrogen or oxygen gas be able to sufficient burning, enlarged area of flame, heat concentrates on soldered zone, realized welding to thick material, not only can be applicable to glass, forming by a firing of quartz ware, non-ferrous metal welds, but also can be applicable to the welding of ferrous metal, and pollution-free again to environment.The utility model is simple in structure, and is easy to manufacture, easy to use.
The drawing of accompanying drawing is described as follows:
Fig. 1 oxyhydrogen flame welding torch nozzle multichannel installation diagram.
Fig. 2 oxyhydrogen flame welding torch nozzle multichannel core retainer plate figure.
Fig. 3 oxyhydrogen flame welding torch nozzle multichannel overcoat figure.
Go on foot explanation below in conjunction with embodiment nearly:
Nozzle is made of core retainer plate 1 and overcoat 2, termination, core retainer plate gas access has M8 * 15mm internal thread to link to each other with welding torch, there is the external screw thread of M8 * 9mm to link to each other with overcoat, core retainer plate inlet termination profile is milled six cylinders of growth 15mm by the round copper rod of φ 12.5mm, core retainer plate length overall 41mm, central bore passage diameter at the core retainer plate SMIS is φ 3mm, is reduced into φ 1.5mm at gas outlet end, the big φ 1.0mm of 4 tap holes on the core retainer plate wall.The long 25mm of overcoat, arrival end have internal thread to link to each other with core retainer plate, and profile is identical with core retainer plate.Nozzle-integratedly be respectively six cylinders, cone from arrival end to the port of export and form, port of export external diameter is φ 8.5mm, overcoat flushes with the core retainer plate port of export, core retainer plate central straight through hole port of export external diameter is φ 5mm, overcoat straight apertures φ 8mm forms a ring-band shape shunting air chamber around the centre bore straight channel after core retainer plate and overcoat join herein.Contraction mouth is processed in the exit, and gas becomes point-like and ejection circlewise from the endless belt chamber from the centre bore straight channel, and the utility model can also overlap some circular holes or the dowel hole of being arranged on the port of export around core retainer plate outside, and gas is shunted ejection once more.
Claims (2)
1, oxyhydrogen flame welding torch nozzle comprises joint screw thread that is connected with welding torch and the nozzle body of being with the centre bore straight channel, it is characterized in that: nozzle is made of the core retainer plate and the outer overcoat of its core retainer plate of socket thereof of the band centre bore straight channel of heart portion, form an endless belt cavity passage around core retainer plate between core retainer plate and the overcoat, the through hole that is communicated with centre bore straight channel and endless belt cavity passage is arranged on the core retainer plate wall, form at least two passages, the port of export of gas has contraction mouth.
2, described by claim 1, oxyhydrogen flame welding torch nozzle is characterized in that: also can around core retainer plate some making be set and shunt the dispersion passage of shunting once more in the shunting gas of endless belt passage at the port of export of overcoat.
