Embodiment Construction

[0013] The specific embodiments of the present invention will be further described below with reference to the examples.

[0014] like figure 1 As shown, a bimetal bushing includes a steel sleeve body made of stainless steel, the inner surface of the steel sleeve body is provided with an electroplating layer, the surface of the electroplating layer is sintered with a wear-resistant layer, and the The angle between the inner surface of the steel sleeve body and the outer surface of the steel sleeve body is 1 degree 30 minutes ± 5 minutes, wherein the electroplating layer is an electroplated copper layer and its thickness is 0.5mm, and the material of the wear-resistant layer is It is CuPb30 and powder, and its thickness is 2.5±0.04mm.

[0015] For those skilled in the art, the technical solutions described in the foregoing embodiments can still be modified, or some technical features thereof can be equivalently replaced, and any modifications made within the spirit and princip...

Abstract

The invention discloses a double-metal bush.A layer of copper, namely an electroplated copper layer is electroplated on the inner surface of a steel sleeve body of a metal bush.Compared with sintering for several times in the prior art, combining of copper and steel is better facilitated, and then copper powder is sintered on the surface of the electroplated copper layer to form a wear-resistant layer, so that number of sintering times is reduced in the whole process and production efficiency is improved.

Description

technical field [0001] The invention relates to a bushing, in particular to a bimetallic bushing. Background technique [0002] At present, the bearing bush needs to be sintered many times in the production process, the production process is complicated, and the input cost is high. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention provides a bimetallic bushing. By electroplating a layer of copper on the inner surface of the steel sleeve body of the metal bushing, that is, an electroplated copper layer, compared with the multiple sintering in the prior art , it is more conducive to the combination of copper and steel, and then the copper powder is sintered on the surface of the electroplated copper layer, that is, the wear-resistant layer. The whole process reduces the number of sintering and improves the production efficiency. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted in the present...
