In rolling, copper pipe is easy to be rolled brokenly, causes waste product, reduces yield rate.
Invention content
The object of the present invention is to provide penetrate aluminum pipe in copper pipe to roll the production technology to form copper clad aluminum wire.
In order to achieve the above objectives, the technical solution adopted by the present invention is：The production technology of copper clad aluminum wire includes following successively
Step：
（1）Copper pipe and aluminum pipe are cleaned, the copper pipe and greasy, the foul of aluminum tube surfaces are removed；
（2）By the inner surface of the copper pipe, the outer surface bristle of the aluminum pipe；
（3）The aluminum pipe is penetrated in the copper pipe, formed copper cladding aluminium pipe, wherein the inner surface of the copper pipe upper bristle with it is described
The outer surface of aluminum pipe upper bristle is mutually in close contact；
（4）Based on required diameter dimension, drawing is carried out to the copper cladding aluminium pipe；
（5）Copper cladding aluminium pipe after drawing is continued through into 370 degree ~ 390 degree intermediate-frequency heating furnaces；
（6）Copper cladding aluminium pipe after heating in medium frequency continues through 378 degree ~ 380 degree holding furnaces；
（7）The copper cladding aluminium pipe come out from the holding furnace rolls on milling train forms copper clad aluminum wire；
（8）Drawing is carried out to the copper clad aluminum wire that rolling is formed, forms uniform copper clad aluminum wire；
（9）The uniform copper clad aluminum wire is made annealing treatment 3 ~ 4 hours at 320 ~ 330 degree；
（10）Surface polishing is carried out to the copper clad aluminum wire after annealing, then obtains finished product.
Preferably, before carrying out drawing to the copper cladding aluminium pipe, end thicker on the copper cladding aluminium pipe is rolled into
Taper end portion, the taper end portion pass through drawing mould, are clamped and are drawn by drawing fixture so that the copper cladding aluminium pipe passes through the drawing die
Tool carries out drawing.
Preferably, in above-mentioned steps（1）Cleaning step in, by the aluminum pipe in sodium hydrate aqueous solution soak at room temperature
Then half an hour is cleaned with clear water, the copper pipe is impregnated 1 hour for 70 degree in copper pipe cleaning agent, is then used clear
Water is cleaned, and the copper pipe cleaning agent is formulated in water by sodium metasilicate, emulsifier, natrium carbonicum calcinatum, tertiary sodium phosphate.
It is further preferred that in 500Kg water, sodium metasilicate 7.5Kg, emulsifier 7.5Kg, natrium carbonicum calcinatum is
7.5Kg, tertiary sodium phosphate 2.5Kg.
It is further preferred that the emulsifier is using the OP emulsifiers to deoil.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art：Copper cladding aluminium pipe is rolling
When forming copper clad aluminum wire, copper pipe, aluminum pipe are deformed, and flat is pressed by circle for rolling on machine, due to aluminum pipe be it is hollow,
In this way other than copper pipe deformation can be supplied to the space that aluminum pipe deforms, the hollow space of aluminum pipe can also accommodate the variant part of aluminum pipe
Point, the defect that copper pipe is rolled brokenly is avoided, yield rate is improved.
Specific implementation mode
It is next below that the present invention is further explained.
The production technology of copper clad aluminum wire cleans copper pipe and aluminum pipe first, for removing the greasy, dirty of copper pipe and aluminum tube surfaces
Object, when cleaning aluminum pipe, by aluminum pipe in sodium hydrate aqueous solution soak at room temperature half an hour, then aluminum pipe is taken out, with height
Hydraulic giant injection clear water is pressed to clean, sodium hydrate aqueous solution is in strong basicity, can be removed greasy, the foul on aluminum pipe dry
Only.When cleaning copper pipe, copper pipe is heated to 70 degree in copper pipe cleaning agent, 1 hour is impregnated, then takes out, it is same with clear
Water is cleaned.Copper pipe cleaning agent is formulated in water by sodium metasilicate, emulsifier, natrium carbonicum calcinatum, tertiary sodium phosphate, wherein
In every 500Kg water, sodium metasilicate 7.5Kg, emulsifier 7.5Kg, natrium carbonicum calcinatum 7.5Kg, tertiary sodium phosphate 2.5Kg.It should
Emulsifier is commercially available using the OP emulsifiers to deoil.Tertiary sodium phosphate, natrium carbonicum calcinatum are in highly basic in aqueous solution
Property, there is preferable cleaning action to copper pipe, emulsifier, sodium metasilicate are for further enhancing clean dirt effect.
After the surface clean of copper pipe and aluminum pipe is clean, the outer surface of the inner surface of copper pipe, aluminum pipe is brushed with Wire brush roller
Hair, in this way after aluminum pipe penetrates in copper pipe and forms copper cladding aluminium pipe, the outer surface of the inner surface and aluminum pipe upper bristle of copper pipe upper bristle
It can be in close contact, prevent aluminum pipe from being slipped from copper pipe；Then drawing is carried out to copper cladding aluminium pipe on drawbench, is made by drawing
Solid phase binding between copper pipe and aluminum pipe is obtained, and pulls into required diameter dimension, before drawing, is needed to copper cladding aluminium pipe system
End thicker on copper cladding aluminium pipe is rolled into taper end portion by head, which can pass through the drawing mould on drawbench, and
It is clamped and is drawn by drawing fixture so that copper cladding aluminium pipe carries out drawing by drawing mould, forms suitable appearance and size.
Copper cladding aluminium pipe after drawing is continued through 370 degree ~ 390 degree intermediate-frequency heating furnaces to heat, through intermediate frequency plus
Copper cladding aluminium pipe after heat continues through 378 degree ~ 380 degree holding furnaces and carries out isothermal holding, and the copper cladding aluminium pipe come out from holding furnace exists
Rolling forms copper clad aluminum wire on milling train, and copper clad aluminum wire includes solid core aluminium, the layers of copper that is coated on solid core aluminium, which may
It is uneven, then it also needs to carry out drawing to the copper clad aluminum wire that rolling is formed, forms uniform copper clad aluminum wire, formed between such copper aluminium
Permanent atom intergranular combines, and is firmly combined with, then makes annealing treatment uniform copper clad aluminum wire 3 ~ 4 hours at 320 ~ 330 degree,
The mechanical performance that copper clad aluminum wire is improved by annealing carries out surface polishing to the copper clad aluminum wire after annealing, then finally obtains into
Product.
When rolling forms copper clad aluminum wire on milling train, copper pipe, aluminum pipe are deformed copper cladding aluminium pipe, are pressed by circle flat
Shape, since aluminum pipe is hollow, in this way other than copper pipe deformation can be supplied to the space that aluminum pipe deforms, the hollow space of aluminum pipe
Also the deformed part that aluminum pipe can be accommodated avoids the defect that copper pipe is rolled brokenly, improves yield rate.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
