Abstract
The utility model provides a copper-aluminum single/double-sided cold composite plate band, which is composed of an aluminum plate layer and copper plate layers positioned at two sides of the aluminumplate layer, wherein the copper plate layers and the aluminum plate layer are mutually fused. The copper-aluminum single-double sided cold composite plate band as a conductive structure is used for an electrical contact device. Copper and a copper joint realize a conductive function, and aluminum and an aluminum joint realize a conductive function and have higher energization performance, are noteasy to be deformed and broken in high temperature and play a joint role for conductive copper/ aluminum simultaneously. In additional, as both surfaces are compounded with red copper or copper alloy, the welding between the part and electrical contacts can not be affected, and steel in the middle can also be projected against eroding at the same time. The advantages of copper and aluminum are utilized furthest, and the adverse effects of the defects of copper and steel on the electrical products are avoided.
Description
Technical field
The utility model relates to the two-sided cold complex plate strip of a kind of copper aluminium list, and the Elecrical connector as in the electrical equipment belongs to the complex plate strip technical field.
Background technology
The copper-aluminum composite board band of the use of the Elecrical connector in electrical equipment at present is made by soldering processes, manufacturing process is: at first the composite surface of material is cleaned with water totally, with sandwiching more low-melting braze in the middle of copper coin and the aluminium sheet, simultaneously sheet material is compressed, put into heating furnace and heat, temperature is controlled in the scolder melting range, solder fusing, two kinds of metal solder are firm, and finished product is cut edge in finish rolling.By this manufacture craft as can be known, there is low-melting solder layer in the strip that obtains between copper and aluminium.The existence of weld layer can influence the electric conductivity, temperature rise of whole strip etc., requires than just inapplicable especially for the higher connector for those conductions.
The utility model content
The purpose of this utility model provides a kind of complex plate strip that conducts electricity very well.
In order to achieve the above object, the technical solution of the utility model has provided the two-sided cold complex plate strip of a kind of copper aluminium list, it is characterized in that, form by aluminum layer and the copper coin layer that is positioned at the aluminum layer both sides, between copper coin layer and the aluminum layer with the mutual diffusion-bonded of copper atom and aluminium atom, realize metallurgical binding, no low melting point layer exists.
The utility model is used for electrical contact spare as conductive structure spare, and copper and copper sleeve are realized conducting function, and aluminium and aluminium joint realize that conducting function has higher energising performance, and not yielding and dialysis during high temperature is played joint action simultaneously to conductive copper/aluminium.In addition because compound red copper in two sides or copper alloy; make that the welding of these parts and other conductor and electric contact is unaffected; aluminium in the middle of yet having protected simultaneously can not held disconnected, makes the advantage of copper and two kinds of materials of aluminium maximize the use, and has avoided the adverse effect of its deficiency to electric equipment products.
The utility model has the advantages that: the very big electric conductivity that must improve complex plate strip.
Description of drawings
The generalized section of a kind of complex plate strip that Fig. 1 provides for the utility model.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, the structural representation of the two-sided cold complex plate strip of a kind of copper aluminium list that provides for the utility model is made up of aluminum layer and the copper coin layer that is positioned at the aluminum layer both sides, and copper coin layer and aluminum layer merge mutually.
Manufacturing process of the present utility model is:
Step 1, calculate the thickness of required aluminium strip and copper strips, the raw band that buying is clean, do not have oil, soft attitude according to the customer requirement pro rata;
Step 2, clean with reconditionings such as the pre-grinding machine of the emery wheel oxide skin that the not pickling on the copper strips faying face is clean, pit, pits;
Step 3, place copper strips, aluminium strip on the unreeling machine respectively, pass automatic brusher, the preceding Roll Collar of machine, composite rolling mill working roll afterwards, after with stub bar reel with winder on, start milling train, brusher, the adjustment roll is depressed, make the rolling reduction of band greater than more than 55%, carry out composite rolling;
Step 4, compound good strip carry out diffusion annealing by continuous annealing furnace to be handled, and temperature is 300 ~ 400 ℃, and speed is 5 meter per seconds, is rolled to the thickness range of customer requirement subsequently by four high finishing mill, and slitting becomes corresponding specification requirement, the packing warehouse-in.
