Abstract
The utility model discloses a copper-aluminum folding pre-rolling plate strip. The copper-aluminum folding pre-rolling plate strip includes an aluminum plate and a copper plate which are folded, and is characterized in that linear or net-shaped dents which are polished by a stainless steel wire brush are arranged on abutted composite faces of the aluminum plate and the copper plate. According to the copper-aluminum folding pre-rolling plate strip, the linear or net-shaped dents which are polished by the stainless steel wire brush are arranged on the abutted composite faces of the aluminum plate and the copper plate to cause lattice deformation to the surface layers of the aluminum plate and the copper plate which need to be rolled, the surfaces can rise to enable the atoms on the copper-aluminum composite face to easily conquer energy barriers required in the combination of heterogeneous metals to form well combination and further effectively improve the combination strength; meanwhile, the roughness of the combination face is increased, so that the static friction coefficient between the composite faces is beneficially improved; and besides, the heat and the shear stress generated by mechanical friction are increased, so that oxidation films are beneficially tore and ground in the plastic deformations of the metals, the contact among pure metals is maintained, and the activity of the contact surface is improved.
Description
Technical field
The utility model belongs to the composite metal plate technical field, is specifically related to the involutory strip of rolling in advance of a kind of copper aluminium.
Background technology
The copper-aluminum composite board band is the composite that coats layer of copper on the surface of aluminium sheet., demand king-sized copper belt wide especially with copper-aluminum composite board band replacement application surface have a wide range of applications at electric power and field of signal transmissions, are expected to form huge industry.
The utility model content
The purpose of the utility model provides a kind of involutory strip of rolling in advance of copper aluminium of effective raising copper aluminium composite surface bond strength.
The technical scheme that realizes the utility model purpose is: the involutory strip of rolling in advance of a kind of copper aluminium, comprise involutory aluminium sheet and copper coin, and it is characterized in that: the composite surface of said aluminium sheet and copper coin adjacency is provided with wire or the netted indenture through the polishing of stainless steel wire brush.
The utlity model has positive effect: (1) the utility model is through being provided with wire or the netted indenture through the polishing of stainless steel wire brush on the composite surface of aluminium sheet and copper coin adjacency; Make the top layer distortion of lattice of treating rolling aluminium sheet and copper coin; Can rise in the surface; Combine needed energy barrier thereby make atom on the copper aluminium faying face be easy to overcome dissimilar metal, form good combination, thereby effectively improve bond strength; Through increasing the roughness of faying face, help improving the confficient of static friction between the composite surface simultaneously; In addition, increase heat and shear stress that mechanical friction produces, tear when helping metal plastic deformation and pulverize oxide-film, the contact that keeps clean metal, active to improve contact surface.

The specific embodiment
(embodiment 1)
Fig. 1 is a kind of structural representation of first kind of structure of the utility model, has shown a kind of specific embodiment of the utility model.
Present embodiment is the involutory strip of rolling in advance of a kind of copper aluminium, sees shown in Figure 1ly, comprises involutory aluminium sheet 1 and copper coin 2, and the composite surface of said aluminium sheet 1 and copper coin 2 adjacency is provided with the wire indenture 3 through the polishing of stainless steel wire brush.
(embodiment 2)
Fig. 2 is a kind of structural representation of second kind of structure of the utility model, has shown the another kind of specific embodiment of the utility model.
Present embodiment and embodiment 1 are basic identical, and difference is: the composite surface of said aluminium sheet 1 and copper coin 2 adjacency is provided with the netted indenture 3 through the polishing of stainless steel wire brush.This meshed grooves 3 is along forming along the polishing of different directions secondary with wheeled wire brush.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these connotations that belong to the utility model are extended out or change still belong to the protection domain of the utility model.
