Abstract
The invention is an alkyne-free pure oxygen cutting torch, belonging to the microwave technical field, comprising oxygen cylinder, reducing valve, gas pipe, protective clothing, operating tool and dissipative material, where metal pipe is around the dissipative material, and combustion supporting metal wire is filled in the dissipative material, the steel pipe plays the role of guiding gas and fixing iron wires, and the metal wire is main combustion supporting material. For providing as much and centralized heat as possible, the arrangement of the iron wires should be as closely as possible, where the arrangement density maximization is the best. And it has higher safety, operating convenience, and low operating technical level requirements for workers, mainly applied to destructive cutting of connecting pieces of ships, large scale mine machines, and so on.
Description
Technical field
The invention belongs to the metal material processing technical field.
Background technology
Need industrial oxygen, acetylene gas during work at present, when cutting or processing work explosive accident may take place.The degree of depth in the hole of processing is restricted.
Summary of the invention
Purpose of the present invention just provides a kind of simple in structure, is easy to process the non-acetylene pure oxygen cutting gun with practical operation.
Operation principle of the present invention is: utilize main component for the metal material of iron under the effect of high pressure industrial oxygen, burning produces high-temperature gas, certain part fusing fast with the workpiece of required processing, metal parts is cut or deep hole machining, be that a kind of steel material deep hole scene adds multiplexer, be mainly used in the efficient roughing fast at metal material part scene.
Chemical equation is:
3Fe (solid)+2O2 (gas)=Fe3O4 (solid)+1119.13kJ
Based on above-mentioned reaction equation, can utilize the reaction heat of emitting, make be cut, the part of processing object near or reach molten state, under the souring of hyperbaric oxygen air-flow, realize the processing in cutting or hole.Iron is combustion medium in this process, be equivalent to the acetylene in the oxy-acetylene flame, and oxygen is combustion-supporting medium, plays a part to support burning and deslagging.
Technical solution of the present invention is to the present invention includes the oxygen cylinder, pressure-reducing valve, the tracheae that connect successively; Protector; Operation tool; Consumptive material.The periphery of consumptive material is a metal tube, and inside is the combustion-supporting wire of filling, and wherein: steel pipe plays a part air guide and fixing iron wire; Inner wire is main combustion-supporting material.For heat many as far as possible and that concentrate is provided, the arrangement of iron wire should be tried one's best closely, turns to the best with the density maximum of arranging.
The selection of metal tube and wire phosphorus content
From iron-carbon phase diagram as can be known, the content of carbon is low more, and the fusing point of steel is also just high more, therefore, must select mild steel for use.For guaranteeing the wider cutting or the scope of processing object, metal tube and inner wire material selection phosphorus content scope are 0.008%～0.1%.Consider burning situation, metal tube is because of contacting with outside air, its ignition temperature and ambient oxygen tolerance are all a little less than inner iron wire, but therefore the combustion heat that will guarantee iron wire simultaneously can, should not make metal tube burn rate and inner wire synchronous because of too fast the forfeiture in air of outside steel pipe burning, comprehensive two aspect factors, be to realize the best combustion effect, the phosphorus content of steel pipe should keep identical with iron wire or difference small, thickness of steel pipe also should be close with the iron wire diameter.
The beneficial effect that the present invention reached is:
(1) safe and reliable.Owing to only need industrial oxygen during work, do not need acetylene gas, contingent explosive accident when thoroughly having avoided oxygen+acetylene gas cutting or processing work.
(2) degree of depth in machinable hole is unrestricted.The degree of depth in hole can reach 10～1000mm.
(3) can process the deep hole of different-diameter by the outside dimension that changes consumptive material; After cutting off oxygen, processing work stops automatically, operates very simply, can increase substantially work efficiency.
(4) the present invention is specially adapted to can not or be difficult for at present existing commonsense method the deep hole on-the-spot roughing and the cutting etc. fast of realization.
(5) cost analysis: we are designed, and to add multiplexer be to be combustion-supporting burning medium with metal, and metal wastage is also bigger, to compare cost higher with traditional oxy-acetylene flame processing method for this, possible incompatibility is used for using on a large scale and promoting, but in some special industries, particularly in the working environment complexity, the occasion that safety requirements is higher, as: the cutting of the medium-and-large-sized corrosion bolt of shiprepair process etc., this cutting, processing mode and traditional oxy arc cutting, processing method by comparison, higher security is arranged, also have easy and simple to handle, operating technology level to the staff requires characteristics such as low.
(6) cutting, processing object: because the restriction of this special process device principle, cutting, the crudy of this method relatively poor (coarse) is not suitable for finishing operations.Mainly be applicable to the destructive cutting of connectors such as boats and ships and large-scale mine machinery.
