Description

Multi-purpose low-temperature soldering machine

The utility model belongs to welding equipment

The soldering of metal low temperature, be widely used in the production of industrial and agricultural products and daily living article with in repairing, as the soldering (as cooking stove oil suction dirt device) of repair welding, family expenses or the industrial sheet iron equipment of the processing of the lead welding of the reparation weldering of automobile radiators water tank, battery, glassware, aluminium basin and the soldering of other hardware commodity.Present existing low temperature is welded with employing oxygen--acetylene welding and flatiron weldering, but it is all undesirable, the former is because of oxygen--and the workpiece of ignition temperature too high (more than the 1200C) soldering of acetylene is generally thinner, therefore the flexible distortion of postwelding workpiece even burn, so that the soldering weak effect of weldment or at all can not weld, latter Yin Wendu is lower, solder horn is crossed its operation inconvenience of ambassador, and effect is too low or can't weld at all.Rob as the spray of burning 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 the molten amount of robbing the dress volatilised liq owing to spray is limited, required disconnected squeezing into air very important person break, so only be suitable in the repair of short-term, using, and because the pressure of air reduces gradually along with the increase of consumption, the combustion of mixed gas temperature also changes, therefore the quality of welding and bad.

In order to overcome these disadvantages, the utility model has been made a kind of portable solderer of low-temperature welding that is applicable to, the temperature that its fuel gas produces when soldering is 700～900C, eutectic welding applicable to multiple metal is multiple, as copper spare and soldering, aluminium and the tin of ironcasting, plumbous and the soldering of tin and the soldering of aluminium and aluminium, aluminium and copper, silver and copper, the effect with soldering in these solderings is best.This welding machine is owing to carry air source and combustible gas source, and with this both mist is a fuel gas, and no longer need oxygen, acetylene, the ratio of components of this gaseous mixture can be regulated air capacity by control valve and realize, and the power switch of reason control valve and air compressor machine, pressure indicator all concentrate on card, therefore simple to operate, and the volume of welding machine little, in light weight (about 1.5Kg), also be 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 five metals department, because the utility model occupation of land is little, carry, move conveniently, can be used for the eutectic welding of multiple metal again, therefore also have good practical value.

Fig. 1 is the embodiment that low temperature is used solderer 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 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 of this twice mixing, connect soldering set by many pipeline outputs and use, 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 represented by Pressure gauge 5.The composition ratio of mixed once, secondary mixing fuel gas, implement the power switch of control valve 6,7,8 and air compressor by control valve 7, adjusting air capacity respectively, Pressure gauge 5 all is loaded on the control panel panel of this solderer, so that operating personnel's operation and observation.The utility model air source is stable, and flammable source of the gas also is stable as long as be interrupted the volatilizable liquid 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, the utility model can reach tens times than the work efficiency raising of general soldering.Because combustible gas conveniently uses through reality with general volatilised liq (as gasoline, alcohol), fuel source, the Hao Liang And of flammable liquid is little.This shows that the utlity model has remarkable economical is worth and practicality.

Fig. 2 a is the soldering set of the utility model adapted, Fig. 2 b, Fig. 2 c are respectively A-A, the B-B section of Fig. 2 a, by Fig. 2 a as seen, 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 this soldering set can be made short and small astute and able, so that manipulate.This soldering set is made by the two-way air feed, by Fig. 2 a as seen, one the tunnel fed before this, saw Fig. 2 b by main valve 11() the control total amount, divide two-way then, 13 ejections (seeing Fig. 2 c) of one route intervalve, another route pipe 14 is seen Fig. 2 c through nozzle 18() and spray, valve 12 is the tolerance usefulness in the adjustable pipe 14, the end face of nozzle 18 has an interstitial hole 15 and three apertures 16, there are a plurality of apertures 17 side of nozzle 18, and hole 15,16,17 all can make the burning of combustible gas more abundant.
