Description
Technical field
The present invention relates to a kind of brazing flux spray equipment, especially relate to a kind of brazing flux spray equipment of braze welding type radiator.
Background technology
Aluminium and aluminum alloy surface all have the fine and close oxide-film of one deck, and this layer oxide-film can hinder the wetting and mobile of fusion brazing flux, make weldment implement good combination, need to destroy this layer oxide-film.In the NOCOLOK soldering that China introduces, promptly be to utilize brazing flux (FLUX) to remove aluminium surface this layer oxide-film 90 year mid-term, and brazing flux melts when temperature reaches 565 ℃ of the eutectic temperatures of brazing flux, and the brazing flux of thawing is at aluminium oxide (AL
2O
3) simultaneously spread out, make AL
2O
3The film dissolving of dissociating, along with the further rising of temperature, al-si alloy filler metal begins to melt; And flow to through capillary moving and will combine weld seam crack place, soak into, expansion, then formed joint; Alumal mother metal (300) is not dissolving then, thereby has accomplished whole brazing process.
Radiating tube in the braze welding type radiator, heat-radiation belt, main leaf, side plate part are through above soldering principle, and soldering becomes the core body sub-unit through soldering oven.In this process, how FLUX is added on the aluminium surface is one of them important operation, and brazing flux has many different adding methods: wet shot, dip-coating, atomizing spray, levelling, brush, squeeze bottle, dried spray etc.Wherein the wet shot process is: brazing flux installs in the circular storage tank after by the finite concentration proportioning, under the effect of compression pump, from shower nozzle, sprays before this, drenches product surface, is down together by the air knife unnecessary brazing flux on the product surface that blows off then.Have solder joint to play the barrier effect on the air channel of air knife, nozzle is stainless.The effect of brazing flux has 3 points: the oxide-film (2) that the aluminium surface is removed in (1) is to promote that smooth and easy flow (3) of solder are in brazing process, to prevent surface oxidation once again.An important requirement of brazing flux spray is must evenly be coated with to attach, and especially can not leak spray, has minimum thickness in addition as far as possible, and the meeting of the product surface after soldering colourity is even like this, can prevent not weld, and can also practice thrift cost.The effect of air knife is to blow unnecessary brazing flux off, and is residual too much on product surface to prevent brazing flux, causes long-pending knurl of soldering and brazing flux to pile up.
Defective in the present production process: shower nozzle adjustable (flexibility) scope is little, and the speed of fan is little, and the height of nozzle is low little with width; The angle of air knife and guipure is little, and nozzle be prone to stop up, easy to clean not, uneven, deep mixed, the surperficial grey of surperficial colourity behind the part spray drying; The inboard brazing flux of main leaf is piled up, main leaf outside welding bead, do not weld; Whole pressure of air knife concentrate on the single fin, the having a big risk of fin, and technical process is unstable; Seriously cause brazing flux waste and product first-time qualification rate lower, be merely 41%.
Cause the reason of defective: shower nozzle adjustable scope is little, and the speed of small fan is little, and the height of nozzle is low little with width, and the angle of air knife and guipure is little, has solder joint to play the barrier effect on the air channel of air knife, and nozzle is stainless.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence a kind of risk that can reduce fin to be provided; Nozzle is difficult for stopping up, easy to clean; Can make solder evenly be filled in product surface; The brazing flux spray equipment that main leaf amasss the braze welding type radiator of knurl and failure welding can not appear in the visible obviously solder joint in welding back.
The object of the invention can be realized through following technical scheme: a kind of brazing flux spray equipment of braze welding type radiator, comprise shower nozzle, air knife and guipure, and described shower nozzle, air knife are arranged on the guipure top; It is characterized in that; Described shower nozzle is made up of with the nozzle that its lower end is connected feed pipe, and described air knife comprises fan and bellows, and described fan is arranged on the bellows top; Described bellows lower end is provided with the air channel, and product to be sprayed is placed on the guipure.
The width of described nozzle is 2-5cm.
The material that described nozzle adopts is a Kynoar.
The tapered shape in described bellows lower end constitutes long and narrow air channel.
Described air knife is arranged on the guipure top, and the angle of air knife and guipure is 30-45 °.
Compared with prior art, the present invention has the following advantages:
1, the pressure on the air knife is dispersed on many row's fins, reduces the risk that dispels fin;
2, nozzle is difficult for obstruction, easy to clean;
3, solder flows and well and evenly is filled in product surface;
4, the visible obviously solder joint of welding back product, surperficial colourity is consistent, the shortcoming of long-pending knurl of main leaf and failure welding can not occur, stable technical process.

Fig. 1 is a structural representation of the present invention;
Wherein: 1-shower nozzle, 11-feed pipe, 12-nozzle, 2-product to be sprayed, 3-air knife, 31-bellows, 32-air channel, 4-guipure.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
As shown in Figure 1, a kind of brazing flux spray equipment of braze welding type radiator comprises shower nozzle 1, air knife 3 and guipure 4; Described shower nozzle 1, air knife 3 are arranged on guipure 4 tops; Described shower nozzle 1 is made up of the nozzle 12 that feed pipe 11 is connected with its lower end, the existing height of aspect ratio of nozzle 12 distances product 2 to be sprayed, and the width of nozzle 12 is also big than existing; Be about 2-5cm, the material that nozzle 12 adopts is PVDF (Kynoar).Described air knife 3 comprises fan and bellows 31; Described fan is arranged on bellows 31 tops, and the wind speed of fan is bigger than existing, the tapered shape in lower end, described bellows 31 lower end; Constitute long and narrow air channel 32; No solder joint is separated the air channel on the air channel 32, and vertically disposed air knife 3 is bigger than existing with the angle of horizontally disposed guipure 4, is about 30-45 °.Product 2 to be sprayed is placed on the guipure 4, transmits through guipure 4, shower nozzle blows unnecessary brazing flux off through air knife after product 2 to be sprayed is gone up in the brazing flux spraying, and is residual too much on product surface to prevent brazing flux, causes long-pending knurl of soldering and brazing flux to pile up.
Product quality situation statistics is shown in table 1 and 2 at present:
Table 1 is the product quality statistical form at present
Improving back product quality situation adds up like table 2 and shown in Figure 4:
Table 2 improves back product quality statistical form
After can knowing improvement by table 1 and table 2, the technical process of product is more stable, and eliminated the product surface grey, defectives such as colourity is all uneven and solder is piled up, the long-pending knurl of main leaf, failure welding.
