Abstract
The invention discloses a manufacturing process for copper aluminum alloy bus bars. According to the technical scheme, the manufacturing process is characterized by comprising the steps of acid pickling, tin plating, aluminum plating and the like of a copper plate in sequence. In the step of aluminum plating, the end, plated with tin, of the copper plate is immersed in molten aluminum, the copper plate is stirred, a thin aluminum layer is formed at the end, plated with tin, of the copper plate, then the copper plate is taken out of the molten aluminum, the end, provided with the thin aluminum layer, of the copper plate is placed in a corresponding die, and molten aluminum is poured into the die for casting molding. By means of the manufacturing process for copper aluminum alloy bus bars, manufactured copper aluminum alloy bus bars have better electrical conductivity and higher electric corrosion resistance, and the manufacturing process is simple and convenient to implement.
Description
Technical field
The present invention relates to a kind of manufacture method of busbar, more particularly, it relates to a kind of albronze busbar manufacturing process.
Background technology
Busbar also claims bus bar, is usually used in power distribution equipment as conductive material.In order to ensure the electric conductivity of busbar on compared with the basis of low production cost, the copper busbar of conventionally selecting a side to be coated with aluminium is albronze busbar.Existing albronze busbar manufacturing process generally includes the pickling of copper coin, zinc-plated, the step such as aluminize, and the copper coin that conventionally directly one end is coated with to tin in its step of aluminizing is put into corresponding mould and added aluminium water to carry out cast molding to it.Usually there is the impurity such as the oxide of bubble or copper in the junction of two kinds of metals of copper aluminium and reduce the metallurgical binding effect of copper aluminium in the step of aluminizing like this, often there is in use comparatively serious galvano-cautery reaction in the albronze busbar of producing, copper material in albronze busbar is corroded, affect the electric conductivity of albronze busbar, reduced its service life.
Summary of the invention
The deficiency existing for prior art, the object of the present invention is to provide a kind of albronze busbar of making that makes to have good electric conductivity and higher anti-galvano-cautery ability, and the albronze busbar manufacturing process of simple process.
For achieving the above object, the invention provides following technical scheme: a kind of albronze busbar manufacturing process, comprise successively the pickling of copper coin, zinc-plated, the step such as aluminize, in described step of aluminizing, first the one end that copper coin is coated with to tin is immersed in aluminium water and is stirred one end that copper coin makes copper coin be coated with tin and forms thin aluminium lamination, copper coin is taken out from aluminium water, the one end that copper coin is formed to thin aluminium lamination is put into corresponding mould and pours aluminium water into and carry out cast molding again.
Aluminium water is immersed in one end zinc-plated copper coin, because the fusing point of tin will melt rapidly in aluminium water and aluminium water will be attached on copper coin compared with low, and remove accompanying impurity and bubble on copper coin by stirring copper coin, after taking out aluminium water, will form thin aluminium lamination until copper coin, the copper forming like this and the alloy of aluminium contact more full and uniform, conduct electricity very well, there is better galvano-cautery resistance, finally use different moulds to become one end of thin aluminium lamination to carry out cast molding to the row of copper coin according to client's different demands, technique is simple, easy to operate.
The present invention is further set to: state aluminium coolant-temperature gage in the step of aluminizing and remain 670 to 700 DEG C, the stirring time of copper coin in aluminium water is 10 to 30 seconds.
By adopting technique scheme, make the copper coin of normal temperature can on copper coin, adhere to rapidly and form thin aluminium lamination after immersing in aluminium water, the aluminium coolant-temperature gage of 670 to 700 DEG C facilitates solidifying of aluminium a little more than the fusing point of lower 660 DEG C of aluminium normal pressure, stir copper coin and within 10 to 30 seconds, can ensure that effectively removal is originally attached to impurity and the bubble on copper coin and melts the tin that copper bar plates originally, ensures product quality in improving production efficiency.
The present invention is further set to: described acid pickling step is specially copper coin is immersed in 5% dilution heat of sulfuric acid and cleaned 4 to 5 minutes, described zinc-plated step is carried out immediately after acid pickling step finishes and dries copper coin surface, be specially copper coin one end is immersed in tin water and stirred copper coin, then copper coin is taken out and makes copper coin one end form thin tin layer from tin water.
By adopting technique scheme; the grease on copper coin surface and the oxide of copper have been removed in pickling; being aluminized in copper coin surface, (the oxide fusing point of copper is all higher due to the oxide of grease and copper for Shi Buhui; cuprous oxide fusing point is 1235 DEG C; cupric oxide fusing point be 1326 DEG C all higher than the fusing point of aluminium) make copper and aluminium in conjunction with unstable; after pickling, good protection is carried out in the zinc-plated one end that can need to aluminize to follow-up copper coin immediately, the oxide that prevents being infected with grease and generate copper.
Detailed description of the invention
Below a kind of albronze busbar of the present invention manufacturing process embodiment is described further.
A kind of albronze busbar manufacturing process, comprise successively the pickling of copper coin, zinc-plated, the step such as aluminize, first copper coin is immersed in 5% dilution heat of sulfuric acid and clean 4 to 5 minutes, after drying in order to prevent that copper from producing oxide in air or some greases of being infected with in production environment exert an influence to following process, therefore immediately copper coin is carried out zinc-plated, ensure product quality.Getting afterwards copper coin is coated with thin tin layer one end and immerses in aluminium water and stir one end that copper coin makes copper coin be coated with tin and form thin aluminium lamination, aluminium coolant-temperature gage remains 670 to 700 DEG C, the stirring time of copper coin in aluminium water is 10 to 30 seconds, again copper coin is taken out from aluminium water, when being taken out from aluminium water, copper coin can have or not obvious bubble by visually observing one end that copper coin aluminizes, if exist obvious bubble copper coin again need be immersed in aluminium water and stirs, until copper coin is aluminized, one end forms the smooth thin tin layer of smooth surface, the one end that again copper coin is formed to thin aluminium lamination is put into corresponding mould and pours aluminium water into and carry out cast molding.
The albronze busbar electric conductivity of manufacturing by above-mentioned technique is superior, has higher anti-galvano-cautery performance, long service life.The pickling of copper coin, zinc-plated, the step such as aluminize is more scientific and reasonable, and compare and only in the step of aluminizing, increased by a step and copper coin is dipped in aluminium water and takes out the operating process that forms thin aluminium lamination with respect to traditional albronze busbar manufacturing process, production efficiency is higher, product defect rate is low, has application value widely.
