Abstract
The invention relates to a technology for inlaying graphite into a metal base material. The technology for inlaying the graphite into the metal base material includes steps: forming blind holes or through holes in the surface of the metal base material; heating the metal base material to 400-600 centigrade degrees, and inlaying graphite materials into the blind holes or the through holes of the metal base material, or freezing the graphite materials to 70-150 centigrade degrees below zero, and inlaying the graphite materials into the blind holes or the through holes of the metal base material. Compared with the prior art, a product obtained by using the technology for inlaying the graphite into the metal base material is small in friction coefficient and high in bearing strength, and can serve for a long time in a temperature range from minus 70 centigrade degrees to plus 400 centigrade degrees.
Description
Technical field
The present invention relates to a kind of technique of inlaying graphite, especially relate to a kind of technique of inlaying graphite in metal base.
Background technology
In prior art, bearing series products used both at home and abroad mainly adopts technique for sticking.The like product of domestic manufacturers' exploitation has two kinds: a kind of is by bonding way inlaid polytetrafluoroethylsliders composite lubricant in blind hole on metallic spheric surface or in plane or through hole; Another kind inlays graphite material lubricant by bonding way in blind hole on metallic spheric surface or in plane or through hole.Their equal Shortcomings, can have a strong impact on carrying and the resistance to elevated temperatures of self-lubricating metal composite, and cannot ensure the long service performance of structure.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of technique of inlaying graphite in metal base meeting high-mechanic self-lubricating and require is provided.
Object of the present invention can be achieved through the following technical solutions:
The technique of graphite is inlayed in metal base, on the surface of metal base, blind hole or through hole are set, metal base is heated to 400 ~ 600 DEG C, the aperture of blind hole or through hole is expanded by metal molten, utilize pressure head graphite material is embedded into metallic substrate surface arrange blind hole or through hole in, then carry out cooling processing to metal base, the aperture of blind hole or through hole returns to initial size, realizes graphite material and is connected with the firm of metal base.
This technique can also adopt following methods: arrange blind hole or through hole on the surface of metal base, graphite material is chilled to-70 ~-150 DEG C, the size of graphite material reduces, utilize pressure head graphite material is embedded into metallic substrate surface arrange blind hole or through hole in, by the temperature return of graphite material to room temperature, the size of graphite material is replied and is increased, and realizes graphite material and is connected with the firm of metal base.
The material of described metal base is copper alloy, stainless steel, cast iron, 45# steel or bearing steel.
Described metal base comprises spherical bearing, sliding bearing or planar slide track.
Compared with prior art, the present invention makes that the product coefficient of friction obtained is little, and bearing strength is high, according to the applying working condition of client, uses the mode of hot charging to realize inlaying of graphite, meets the instructions for use of high temperature or low temperature.According to the service condition of reality, product can meet in-70 ~+400 DEG C of temperature ranges, can the requirement of use of long service, realizes self-lubricating and function non-maintaining for a long time.
