Abstract
Disclosed is a pretreatment process before brazing of an aluminum radiator core body. The invention relates to the field of the aluminum radiator core body cleaning process. The aluminum radiator core body is cleaned by the following steps: firstly, the aluminum radiator core body is placed on a conveyor belt, the middle segment of operating path of the conveyor belt is sunk, and is dipped into an alkaline cleaning liquid trough, and the aluminum radiator core body is cleaned by ultrasonic wave simultaneously. Then, the aluminum radiator core body is sprayed, rinsed and aired. The invention has the advantages that the using effect of the invention is obvious, the flow is simple, and the extra investment of special fixtures is not needed. Parts need not to be placed separately and artificially during the cleaning process, thereby the manpower is saved, and cheaper cutting oil is used in the processing of a radiating rib so that the production cost is reduced. In addition, the brazing process is implemented directly after the core body is cleaned in a whole, the assembly process is omitted, and the secondary pollution of the parts is avoided.
Description
Technical field
The present invention relates to a kind of aluminum radiator core body cleaning process field.
Background technology
In the prior art, aluminium radiator is to adopt nitrogen-protective soldering technology, belongs to the solder brazing category, so the cleannes to piece surface have quite high requirement on production technology.If there are phenomenons such as greasy dirt, impurity in piece surface, in the process of product soldering, will cause rosin joint, dry joint so even weld not first-class defective fully, have a strong impact on the reliability that radiator uses.And aluminium matter water radiator and copper water radiator maximum different are exactly in case above-mentioned situation occurs, and aluminium radiator is difficult to do over again.Just mean scrapping of product so this situation occurs, bring very big loss to enterprise, so aluminium radiator enterprise all regards cleaning as be only second to soldering important process, domestic modal cleaning way is only to adopt ultrasonic wave to clean to parts now, and radiator core body does not clean substantially, clean halfway hidden danger for fear of the part that causes of fitting owing to part like this, part need be placed in and clean in the basket, each part is all put respectively, increased the investment of cleaning basket, expended great amount of manpower, and heat-radiation belt is placed on to clean cleans in the basket, cause the distortion of heat-radiation belt easily, this need be special volatile oil at the cutting oil that adopts man-hour that adds of heat-radiation belt just, causes the increase of product cost.And after parts clean, before entering the soldering operation, also having an assembly process, this just is easy to cause secondary pollution to part, and influences welding quality.
Summary of the invention
The present invention is directed to above problem, provide a kind of heat sink part not clean, to the whole technology of cleaning of radiator core body, reduced investment to production cost, save manpower, reduced part and cleaned sordid risk, carried out the secondary pollution that soldering processes have been avoided part after whole the cleaning.
Technical scheme of the present invention is: a kind of pretreatment process before brazing of aluminum radiator core body is characterized in that: clean as follows:
1), at first, radiator core body is placed on the conveyer belt, the stage casing of conveyer belt operating path sinks, immerse in the alkaline cleaning fluid groove, alkaline cleaning fluid temperature in the control flume is 55-65 ℃, ultrasonic generator is arranged on alkaline cleaning fluid groove outside, and ultrasonic wave that ultrasonic generator sends and alkaline cleaning fluid clean the radiator core body under the alkaline cleaning fluid liquid level; After going out groove, air-dry;
2) then, radiator core body is sent to spraying mechanism one, with the alkaline cleaning fluid spray, the spray liquid temperature is controlled at 45-55 ℃; After leaving the spray district;
3) then, radiator core body is sent to spraying mechanism two, with pure water radiator core body is carried out rinsing, water temperature is controlled at 30-40 ℃; Air-dry;
4) last, radiator core body is sent to the drying oven hot-air seasoning, temperature is 100-120 ℃ in the drying oven; Cooling makes the radiator core body that can carry out soldering processing.
Advantage of the present invention is: this invention result of use is obvious, flow process is simple, need not increase the investment of extra special tooling, in cleaning process, do not need artificial part is separately put, saved manpower, use cheap more cutting oil in the heat-radiation belt processing, reduced production cost, and directly carry out soldering processes after the whole cleaning of core body, and saved assembly technology, avoided the secondary pollution of part.
The specific embodiment
A kind of pretreatment process before brazing of aluminum radiator core body is characterized in that: clean as follows:
1), at first, radiator core body is placed on the conveyer belt, the stage casing of conveyer belt operating path sinks, immerse in the alkaline cleaning fluid groove, alkaline cleaning fluid temperature in the control flume is 60 ℃, ultrasonic generator is arranged on alkaline cleaning fluid groove outside, and ultrasonic wave that ultrasonic generator sends and alkaline cleaning fluid clean the radiator core body under the alkaline cleaning fluid liquid level; After going out groove, air-dry;
2) then, radiator core body is sent to spraying mechanism one, with the alkaline cleaning fluid spray, the spray liquid temperature is controlled at 50 ℃; After leaving the spray district;
3) then, radiator core body is sent to spraying mechanism two, with pure water radiator core body is carried out rinsing, water temperature is controlled at 35 ℃; Air-dry;
4) last, radiator core body is sent to the drying oven hot-air seasoning, temperature is 110 ℃ in the drying oven; Cooling makes the radiator core body that can carry out soldering processing.
This kind embodiment is a preferred forms, and effect is best.
