Description
Technical field
The present invention relates to metallurgical technology technical field, metallurgical in particular to a kind of copper aluminum interface alloy composite bus
Combined process.
Background technology
Copper-Aluminum compound row is a kind of with aluminum as matrix, external sheath copper.Can be divided into by its manufacturing process: tube-weld cladding technique is
The method of copper-clad aluminum conductor is prepared in home and abroad, and some enterprise domestic makes copper clad aluminum wire by this kind of technique, and this method is to use
Flat, edger roll is suppressed with core, is coated on aluminum row by concentric for copper strips, and then longitudinal joint carry out argon arc welding, more stretched, move back
Fire.Copper strips through cleaning treatment is crimped on aluminium sheet by rolling crimping from upper and lower two wide faces, and utilizing roll to apply pressure will
Copper strips and aluminium sheet are crimped together, the most orthopedic or be further processed after annealing, existing prepare the compound mother of copper aluminum interface alloy
It is big and produce discontinuous generally to there is equipment investment in the process of line, inefficient or after improving production efficiency, produces
The composite bed of Copper-Aluminum compound row out is the thinnest, and bond strength is low, and existing preparation method all can not realize Copper-Aluminum compound row's
Widespread production uses.
Summary of the invention
It is an object of the invention to provide a kind of copper aluminum interface alloy composite bus metallurgical binding technique and improve copper to arrive
The purpose of the bond strength of the production efficiency of aluminum composite bar, reduction production cost and raising Copper-Aluminum compound row, solves existing
Copper-Aluminum compound row's equipment investment is big and produces discontinuous, the problem inefficient, composite bed is the thinnest and bond strength is low.
For realizing the object of the invention, the technical scheme of employing is: a kind of copper aluminum interface alloy composite bus metallurgical binding work
Skill, it is characterised in that include copper pipe, aluminium sheet, add hot tank and hydraulic press, specifically comprising the following steps that of its metallurgical binding technique
(1) inner surface of copper pipe is purged oxide-film process and put into and add hot tank and be preheated to 350 DEG C～450 DEG C,
Aluminium sheet is carried out high temperature melting；
(2) warmed-up copper pipe is put in the concave die cavity of hydraulic press, then the aluminum liquid after high temperature melting is fixed
Amount is poured in concave die cavity；
(3) hydraulic press carries out crushing failure at high speed molding by concave die cavity, and after being incubated 1～2 hour, hydraulic press is ejected also
It is positioned in air cooling 5～8 hours.
Further, the aluminium sheet in described step (1) needed to remove the oxide layer on its surface before high temperature melting.
Employing present invention have the advantage that
1, good electric conductivity: copper aluminum volume ratio is the copper clad aluminum wire electrical property of 15%, its ac compared with copper bar
Amount is the 85% of fine copper；
2, lightweight: the density of copper clad aluminum wire is only the 37%-40% of fine copper row, and the length (volume) of equivalent weight is pure
2.5-2.7 times of copper bar；
3, good mechanical property: there is good tensile strength, flexible and elongation percentage；
4, combine between firm copper aluminum: reach permanent former between two kinds of different metal materials in various ambient temperatures
Sub-intergranular combines, and layers of copper (tin plating, zinc layers) is evenly distributed, and there is not any physical imperfection；
5, good ductility and reliability: through special Technology for Heating Processing, have certain plasticity, be conducive to punching
Hole, shearing, bending machining product do not ftracture, do not separate.In order to improve corrosion resistance, tin plating, plating can be carried out on layers of copper surface
Zinc processes；
6, optimal selectivity: save copper material, greatly reduces and produces supporting cost, and environmental protection, without any pollution.
Detailed description of the invention
Below by specific embodiment, the present invention is described in further detail.
A kind of copper aluminum interface alloy composite bus metallurgical binding technique, it is characterised in that include copper pipe, aluminium sheet, add hot tank
And hydraulic press, specifically comprising the following steps that of its metallurgical binding technique
(1) inner surface of copper pipe is purged oxide-film process and put into and add hot tank and be preheated to 350 DEG C～450 DEG C,
Aluminium sheet is carried out high temperature melting；Choose preheating temperature as practical situation to be 400 DEG C and heat；
(2) warmed-up copper pipe is put in the concave die cavity of hydraulic press, then the aluminum liquid after high temperature melting is fixed
Amount is poured in concave die cavity；
(3) mixture in concave die cavity is carried out crushing failure at high speed molding by hydraulic press, is incubated 1～2 hour, and hydraulic press is by it
Eject and be positioned in air and cool down 5～8 hours；Insulation 1.5 hours, cooling 7 hours is chosen, to reach as practical situation
Good metallurgical binding effect.
Aluminium sheet in described step (1) needed to remove the oxide layer on its surface before high temperature melting, owing to aluminium sheet is entering
Being positioned over before row high temperature melting in the middle of air, aluminium sheet easily reacts with air generation oxidation film layer, if oxidation film layer is not
Anticipate, follow-up Cu and Al combination intensity will be caused the biggest impact, be unfavorable for that the copper aluminum of output high intensity is multiple
The row of conjunction.
Described above process technique is under oxygen free condition being compounded to form, and there is not generation electrolysis between two kinds of metals
The condition of matter, because of without producing couple corrosion.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
