Abstract
The invention discloses a kind of albronze busbar manufacturing process, its drip irrigation device is to include the pickling of copper coin successively, tin plating, the step such as aluminize, in the described step aluminized, first copper coin is coated with one end of stannum immerse in aluminum water and stir one end that copper coin makes copper coin be coated with stannum and form thin aluminium lamination, again copper coin is taken out from aluminum water, copper coin is formed one end of thin aluminium lamination put in corresponding mould and pour aluminum water into and carry out cast molding, aim to provide a kind of albronze busbar making making and there is preferable electric conductivity and higher anti-galvano-cautery ability, and the albronze busbar manufacturing process of simple process.
Description
Technical field
The present invention relates to the manufacture method of a kind of busbar, more specifically, it relates to a kind of albronze busbar manufacturing process.
Background technology
Busbar is also referred to as bus bar, is usually used in power distribution equipment as conductive material.In order to ensure the electric conductivity of busbar on the basis of relatively low production cost, side is generally selected to be coated with the copper busbar i.e. albronze busbar of aluminum.Existing albronze busbar manufacturing process generally includes the pickling of copper coin, tin plating, the step such as aluminize, and one end is typically directly coated with in its step aluminized the copper coin of stannum and puts in corresponding mould and add aluminum water it is carried out cast molding.Such step aluminized usually occurs in the junction of two kinds of metals of copper aluminum that the impurity such as the oxide of bubble or copper reduce the metallurgical binding effect of copper aluminum, the albronze busbar produced tends to occur the most serious galvano-cautery reaction in use, the copper material in albronze busbar is made to corrode, affect the electric conductivity of albronze busbar, decrease its service life.
Summary of the invention
The deficiency existed for prior art, it is an object of the invention to provide a kind of albronze busbar making making and has preferable electric conductivity and higher anti-galvano-cautery ability, and the albronze busbar manufacturing process of simple process.
For achieving the above object, the technical scheme is that a kind of albronze busbar manufacturing process, include the pickling of copper coin, tin plating, the step such as aluminize successively, in the described step aluminized, first copper coin is coated with one end of stannum immerse in aluminum water and stir one end that copper coin makes copper coin be coated with stannum and form thin aluminium lamination, again copper coin is taken out from aluminum water, copper coin is formed one end of thin aluminium lamination and puts in corresponding mould and pour aluminum water into and carry out cast molding.
Aluminum water is immersed in one end tin plating for copper coin, owing to the fusing point of stannum is relatively low, by melting rapidly in aluminum water, aluminum water will attach on copper coin, and remove impurity accompanying on copper coin and bubble by stirring copper coin, thin aluminium lamination will be formed after copper coin takes out from aluminum water, the copper so formed and the alloy contact of aluminum are more full and uniform, conduct electricity very well, there is preferable galvano-cautery resistance, finally different moulds is used to become one end of thin aluminium lamination to carry out cast molding the row of copper coin according to the different demands of client, technique is simple, easy to operate.
The present invention is further arranged to: states aluminum coolant-temperature gage in the step aluminized and remains 670 to 700 DEG C, and the copper coin agitation time in aluminum water is 10 to 30 seconds.
By using technique scheme, the copper coin making room temperature can adhere on copper coin and form thin aluminium lamination rapidly after immersing in aluminum water, the fusing point of the aluminum coolant-temperature gage of 670 to 700 DEG C slightly above lower 660 DEG C of aluminum normal pressure facilitates the solidification of aluminum, agitation copper coin can ensure effectively remove the impurity being originally attached on copper coin and bubble and melt the stannum that copper bar is plated originally for 10 to 30 seconds, ensures product quality while improving production efficiency.
The present invention is further arranged to: described acid pickling step is specially to immerse in 5% dilution heat of sulfuric acid copper coin and cleans 4 to 5 minutes, described tin plating step is carried out after acid pickling step terminates and dries copper coin surface immediately, it is specially and copper coin one end is immersed in stannum water and stirred copper coin, then copper coin is taken out from stannum water make copper coin one end formation thin layer of tin.
By using technique scheme; pickling eliminates the oils and fats on copper coin surface and the oxide of copper; will not (oxide ester mp of copper be the highest due to the oxide of oils and fats and copper time being aluminized in copper coin surface; Red copper oxide fusing point is 1235 DEG C; copper oxide fusing point is 1326 DEG C is above the fusing point of aluminum) make copper and aluminum combine instability; after pickling, the most tin plating one end can aluminized follow-up copper coin needs carries out good protection, prevents from being infected with oils and fats and generating the oxide of copper.
Detailed description of the invention
Below one albronze busbar manufacturing process embodiment of the present invention is described further.
A kind of albronze busbar manufacturing process, include the pickling of copper coin, tin plating, the step such as aluminize successively, first copper coin is immersed in 5% dilution heat of sulfuric acid and clean 4 to 5 minutes, after drying, some oils and fatss in order to prevent copper from producing in atmosphere in oxide or contamination production environment produce impact to following process, the most immediately copper coin is carried out tin plating, it is ensured that product quality.Take copper coin afterwards to be coated with thin layer of tin one end and immerse in aluminum water and stir one end that copper coin makes copper coin be coated with stannum and form thin aluminium lamination, aluminum coolant-temperature gage remains 670 to 700 DEG C, the copper coin agitation time in aluminum water is 10 to 30 seconds, again copper coin is taken out from aluminum water, one end that copper coin aluminizes can be observed by the naked eye with or without obvious bubble when being taken out from aluminum water by copper coin, copper coin need to be immersed again in aluminum water if there is obvious bubble and stir, until copper coin is aluminized, one end forms the thin layer of tin that smooth surface is smooth, copper coin is formed one end of thin aluminium lamination again put in corresponding mould and pour aluminum water into and carry out cast molding.
The albronze busbar electric conductivity manufactured by above-mentioned technique is superior, has higher anti-galvano-cautery performance, and service life is long.The pickling of copper coin, tin plating, the step such as aluminize is more scientific and reasonable, and compare relative to traditional albronze busbar manufacturing process and in the step aluminized, only to add a step copper coin is dipped in aluminum water and takes out the operating process forming thin aluminium lamination, production efficiency is higher, product defect rate is low, has application value widely.
