Description

Low temperature gas welder for multiple-use

The invention belongs to bonding machine.

The soldering of metal low temperature, be widely used in the production of industrial and agricultural products and daily living article with in repairing, all will adopt eutectic welding as the welding (as cooking stove oil suction dirt device) and the welding of other hardware commodity of repair welding, family expenses or the industrial sheet iron equipment of the processing of the lead welding of the multiple weldering of automobile radiators water tank, battery, glassware, aluminium basin.Present existing low temperature is welded with and adopts oxy-acetylene welding and ferrochrome weldering, but it is all undesirable, the former makes the welding effect difference of weldment because of the ignition temperature of oxy-acetylene too high (more than 1200 ℃) or can not weld at all, latter Yin Wendu is lower, the ferrochrome head cross ambassador its to operate inconvenient effect too low or can't weld at all.The spray gun that acts as a fuel with fuel gas and Air mixing gas, it also is a kind of special-purpose soldering set, its in some repair work (as welding of the polylinker in the telephone line) has been a kind of common tool, but because the finite capacity of spray gun dress volatilised liq, required disconnected squeezing into air very important person break, so being applicable to that inconvenience such as field work or building site are carried in the repair of short-term of welding equipment uses, and because the pressure of air reduces gradually along with the increase of consumption, the ignition temperature of gaseous mixture also changes, therefore the quality of welding and bad.

In order to overcome these disadvantages, the present invention has made a kind of portable gas welding machine of low-temperature welding that is applicable to, the temperature that its fuel gas produces when welding is 700～900 ℃, multiple as copper spare and soldering, aluminium and the tin of ironcasting, plumbous and the welding of tin and the welding of aluminium and aluminium, aluminium and copper, silver and copper applicable to the eutectic welding of multiple metal, wherein the effect with soldering and lead welding is best.This welding machine is owing to carry air source and combustible gas source, and both mist is a fuel gas with this, and no longer needs oxygen, acetylene, the ratio of components of this gaseous mixture.Regulate air capacity by control valve and realize, and the power switch of all control valves and air compressor machine, pressure indicator all concentrates on card, so welding machine is easy and simple to handle, and volume little (about 15kg) in light weight, is easy to carry.This is for the area of oxygen supply inconvenience or carry the occasion of oxygen cylinder, acetylene unit inconvenience, with the most suitable.For the five metals repairing department, because the present invention is taken up an area of for a short time, carry, move conveniently, can be used for the eutectic welding of multiple metal, therefore also have good practical value.

Fig. 1 is the embodiment that low temperature is used bonding machine more, and it is by the source of air compressor 1 as air, with adorning the source of the evaporimeter 2 of volatile flammable liquid as combustible gas.Air is come out by compressor, enter air distributor 3, divide two-way output then, wherein one the tunnel enter evaporimeter 2, and combustible gas is taken out of from evaporimeter together, this is called mixed once fuel gas, it introduces mixing chamber 4 with pipeline with this fuel gas, and carry out secondary with another road air of exporting by distributor 3 again and mix, the fuel gas that this secondary mixes connects soldering set by many pipelines outputs and uses.The way that the air total amount of distributor 3 is regulated discharge quantity by valve 6 usefulness among the present invention keeps, and is indicated by Pressure gauge 5.The composition ratio of mixed once, secondary mixing fuel gas, regulate air capacity by control valve 7,8 respectively and implement the power switch of control valve 6,7,8 and air compressor, Pressure gauge 5 all is loaded on the control panel panel of this bonding machine, so that operating personnel's operation and observation.Because air of the present invention source is stable, flammable source of the gas also is stable as long as be interrupted the flammable volatilised liq of adding, therefore this welding machine can use continuously, and the output of the bull of its fuel gas, the characteristics that can supply the several people to operate simultaneously make the present invention improve than general welding machine work efficiency and can reach tens times.Because of combustible gas gets final product with general volatilised liq (as gasoline, alcohol), so fuel source is convenient, to use through reality, the consumption of flammable liquid is also little.This shows that the present invention has that remarkable economical is worth and practicality, and gas welder is made special machine is that its originality is arranged.

Fig. 2 is the soldering set of adapted of the present invention, because feeding the fuel gas of soldering set has been the gaseous mixture of air and combustible gas, this gas no longer will mix in soldering set as oxygen, acetylene in soldering set, so that this soldering set can be made is short and pithy, manipulates to be more convenient for.This soldering set is still made by the two-way air feed, as seen from Figure 2, one the tunnel fed before this,, divided two-way then by main valve 1 control total amount, one route intervalve, 3 ejection (see figure 3)s, another route pipe 4 is seen Fig. 3 through nozzle 1() and spray, valve 2 is the tolerance in the adjustable pipe 4, the end face of nozzle 1 has an interstitial hole 5 and three apertures 6, there are a plurality of apertures 7 side of nozzle 1, and aperture 5,6,7 is and makes the burning of combustible gas more abundant.
