Background technology
It is known that natural resources is non-renewable, but some natural resourcess are as the demand of socio-economic development
Consume constantly, the today how to accelerate at economic development paces, the production of environment-friendly products can be met rationally and effectively
Demand, can save and reduce again the consumption of natural resources, and this is the big problem that development in Hi-Tech is faced period.China is lean
The country of copper richness bauxite resource, commercial bronze major part is from external import, and bauxite resource production capacity surplus.Country is interior in order to disappear in recent years
The superfluous aluminum production capacity of consumption, Ministry of Industry and Information strengthens utilization and extention bauxite resource innovative product, goes stock, drops production capacity.How to make full use of aluminum money
The advantage in source carrys out saving copper resource, develops with aluminum for copper novel high-efficiency and energy-saving conductor material, for the deposit wound of country's copper resource
Making condition, this is imperative, is also that we make great efforts to realize.
Summary of the invention
It is an object of the invention to provide and a kind of conduct electricity the copper aluminum interface alloy composite pipe that flow is big, temperature rise low heat emission performance is good
The production method of bus.
In order to realize foregoing invention purpose, technical scheme is specific as follows:
The production method of a kind of strong conduction copper of resistance to temperature rise aluminum interface alloy composite pipe bus, it is characterised in that comprise the following steps:
1) pretreatment: remove aluminum tube surfaces oxide layer, the spiral plucking of alignment, clean with water the most standby；Cleaning copper pipe inner wall oxide
Thing, copper pipe inwall plucking stings, and cleans with water clean, and alignment is standby；
2) suit end socket: after pretreatment, aluminum pipe is penetrated in copper pipe, standby after the end socket of two ends, obtain Cu-Al bimetal
Blank；
3) drawing: by Cu-Al bimetal blank drawing to seamless rear standby, obtain non-oxidation Cu-Al bimetal blank；
4) interface cohesion: non-oxidation Cu-Al bimetal blank is placed in medium-frequency generator under nitrogen atmosphere and is heated to metal and melts
Point hot melt, obtains Mao Pintong aluminum interface alloy；
5) extrusion cladding: Mao Pintong aluminum interface alloy extrusion cladding molding web in proportion；
6) drawing and moulding: the molding web compound by calendering, with mould drawing shaping, separated time scale, makes the copper of all size
Aluminum interface alloy composite bus；
7) surface processes: by the copper aluminum interface alloy composite bus surface finish after drawing and moulding, passivation drying and processing；
8) inspection warehouse-in: pack warehouse-in after quality inspection is qualified.
Preferably, in described aluminum pipe, aluminum mass percent is not less than 99.7%.
Preferably, in described oxygen-free copper pipe, copper mass percent is not less than 99.9%.
Preferably, copper pipe inwall plucking thorn 3-5 micron in step 1.
Preferably, in step 4, the frequency of described medium-frequency generator is 350-450Hz.
The method have the benefit that copper aluminum interface alloy composite pipe bus has conductivity high, temperature rise is low, and heat dispersion is strong,
Improve the advantages such as current-carrying capacity, the loss of reduction electric energy.Aluminum in the alloy composite pipe bus-bars conductor of copper aluminum interface of the present invention can carry
The electric current of global sections current-carrying capacity 50%, through without the special thermal treatment of any pollution and environment is extruded drawing work, makes it have
Have good tensile strength, and bendability and an elongation percentage, can die-cut bending machining, saving copper resource 52%, is a kind of saving copper
Resource, low power consuming, Novel environment-protective energy-saving conductor material.
Detailed description of the invention
Below in conjunction with embodiment, present disclosure is described in further detail.
