Abstract
The invention discloses the production method of a kind of copper coated aluminum bus bank, comprise the following steps: 1. carry out scrubbing removing oxide skin by the surface of copper pipe and aluminium sheet with iron wire brush, in noble gas, aluminium sheet is loaded in copper pipe, prevent from aoxidizing for a long time；2. the copper aluminum blank molectron installed by set is put into Efco-Northrup furnace and is heated, and heating-up temperature is 500 700 DEG C, and roll compacting elongation moulding shuts out the cuprum alclad rectangular bus bar of different size；3. according to user's requirement, conventional annealing is carried out.Bi-material is perfectly combined by the production method of a kind of copper coated aluminum bus bank of the present invention, both the characteristic that copper surface oxidation-resistant is strong had been maintained, take full advantage of again the lightweight advantage of aluminum, after three roll compacting extends, good percentage elongation, copper coated aluminum bus bank good conductivity, lightweight, production efficiency is high, percent defective is low.
Description
Technical field
The present invention relates to the manufacture method of the bus bar that a kind of power industry uses, especially relate to a kind of copper wrapped aluminum bus
The production method of row.
Background technology
Copper wrapped aluminum bus-copper clad aluminum wire bus is that the row's core as bus bars arranged by a kind of fine aluminium, uses certain thickness
Copper coin material as bus bars outer contact and install contact surface, constitute copper wrapped aluminum bus busbar.Copper wrapped aluminum bus
Busbar is possible not only to replace fine copper row's bus bars, it is also possible to applies and transmits occasion with fine copper row as electric current at other
Under, replace original copper bar with copper clad aluminum wire, effectively reduce busbar cost about 50%.Copper wrapped aluminum bus-copper clad aluminum wire product is special
Point: 1, replace original copper bar with copper clad aluminum wire, effectively reduces busbar cost about 50%.2, volume ratio 17-20%, proportion 3.7,
Copper content 40%.3, conductivity reaches about the 85% of fine copper row.4, copper aluminum interface is completely combined, shearing, bending, punching, copper aluminum
Operation requirement that is not stratified, that meet copper bar processing, use, can substitute copper bar.5, contact resistance, resistance to corrosion, superficiality
Can be just the same with copper bar.6, good mechanical property, tensile strength, case hardness are more much higher, close to copper bar than aluminum row.7, proportion
Little, lightweight, use installation more convenient, service life is long.8, in various ambient temperatures, reach permanent former between copper aluminum
Sub-intergranular combines, and layers of copper (tin plating, zinc layers) is evenly distributed, and there is not physical imperfection, but present copper coated aluminum bus bank
Manufacturing process due to drawing numbers too many, cause yield rate low, of poor quality.

In, prevent from aoxidizing for a long time；
2. the copper aluminum blank molectron installed by set is put into Efco-Northrup furnace and is heated, and heating-up temperature is 500-700 DEG C, rolls
Pressure elongation moulding, shuts out the cuprum alclad rectangular bus bar of different size；
3. according to user's requirement, conventional annealing is carried out.
Described roll compacting extends to three roll compacting and extends.
Thickness after described described copper roll compacting extends is 0.6mm.
Described step 1. scrub step include cleaning copper pipe step:
Copper pipe is immersed in half an hour in copper pipe abluent, with steel brush, copper pipe is scrubbed, after scrubbing clean, use overflow water
It is rinsed.
Described step 1. scrub step include cleaning aluminum pipe step:
Aluminum pipe abluent and water are mixed to form cleanout fluid according to the ratio that weight ratio is 1:5, aluminum pipe is immersed in cleanout fluid
Scrub clean with steel brush after half an hour.
The present invention has a following remarkable advantage:
The production method of a kind of copper coated aluminum bus bank of the present invention due to comprise the following steps that 1. with iron wire brush by copper pipe and aluminium sheet
Surface carry out scrubbing removing oxide skin, in noble gas, aluminium sheet is loaded in copper pipe, prevents from aoxidizing for a long time；2. will suit
Good copper aluminum blank molectron is put into Efco-Northrup furnace and is heated, and heating-up temperature is 500-700 DEG C, roll compacting elongation moulding,
Shut out the cuprum alclad rectangular bus bar of different size；3. according to user's requirement, carrying out conventional annealing, the method is complete by bi-material
Beautiful combines, and has both maintained the characteristic that copper surface oxidation-resistant is strong, has taken full advantage of again the lightweight advantage of aluminum, scrub
Step enables copper pipe preferably to combine with aluminum pipe, after three roll compacting extends, and good percentage elongation, copper coated aluminum bus bank
Good conductivity, lightweight, production efficiency is high, percent defective is low.
