Abstract
The invention discloses a production technology of a mechanical abrasion resisting piece. Graphite is embedded in a copper alloy matrix through glue. The copper alloy and graphite materials have complementary advantages. The copper alloy and the graphite have the respective advantages after being combined. The superior performance such as high strength, fast heat conducting and good electrical conductivity of a copper base body and the superior lubrication and friction reduction performance of the graphite are combined. The bearing capability is achieved, the limit that ordinary bearings are lubricated through oil film grease is broken through, and oilless lubrication is achieved.
Description
Technical field
The present invention relates to mechanical wearing piece technical field, is specifically a kind of production technology of mechanical wearing piece.
Background technology
In manufacturing machine wearing piece process, usually Cu alloy material can be used, and copper alloy have the features such as good heat conductivity, stronger intensity, arc ablation resistance, excellent electric conductivity.Thus, Cu alloy material has demand field very widely, and its application is dispersed throughout the field that Aero-Space, traffic, machine driving, military affairs etc. require to possess excellent abrasive resistance and good electric conductivity.
Along with the develop rapidly in the fields such as Aero-Space, traffic, machine driving, military affairs, on the one hand the demand of Cu alloy material is surged, on the other hand the performance of Cu alloy material is had higher requirement, current low performance copper alloy composite material is more and more unable to do what one wishes, modal is exactly coefficient of friction low problem in large and service life, directly have influence on the performance of the Whole Equipment performance in each demand field, become the bottleneck of each application development of restriction.
So, how to develop high performance copper alloy machinery wearing piece, be this area staff institute for study direction.
Summary of the invention
In view of the defect of above-mentioned prior art, the object of the invention is to: the production technology that a kind of mechanical wearing piece is provided, the performance of wearing piece can be improved, reduce the coefficient of friction of wearing piece, and improve the service life of wearing piece.
Technical solution of the present invention is: a kind of production technology of mechanical wearing piece, is characterized in that, carries out according to subordinate's step:
Step (1): to copper alloy matrix processing, various metal is melted according to component and proportioning and merges, melt temperature is 350-500 DEG C and carries out casting processing;
Step (2): hole on copper alloy matrix;
Step (3): inlaid solid lubrication material, solid lubricant is graphite, the graphite that processing matches with the shape size in the hole on copper alloy matrix, with glue, graphite is inlayed in hand-hole, and the mosaic area of graphite is the 20%-35% of the surface area of copper alloy matrix Relative friction motion;
Step (4): to the Surface Machining of solid lubricant.
Further, the mosaic area of graphite is the 25%-30% of the surface area of copper alloy matrix Relative friction motion.
Apply the production technology of a kind of mechanical wearing piece provided by the present invention, its beneficial effect is: copper alloy and graphite material have had respective complementary advantage, copper alloy and graphite have had respective advantage after bonding, have the high strength of Copper substrate concurrently, heat conduction is fast, the excellent properties such as good conductivity and the excellent lubrication antifriction performance of graphite, both bearing capacity had been possessed, breach again the boundary that general bearing relies on oil film grease lubrication, achieve oil-free lubrication, very large improvement result is served to friction and wear behavior, stability is high, automobile industry can be widely used in, die industry places machinery and automation equipment industry.
Detailed description of the invention
For more intuitively, intactly understanding technical scheme of the present invention, existing just to carry out nonrestrictive feature description as follows:
A production technology for mechanical wearing piece, is characterized in that, carries out according to subordinate's step:
Step (1): to copper alloy matrix processing, various metal is melted according to component and proportioning and merges, melt temperature is 350-500 DEG C and carries out casting processing;
Step (2): hole on copper alloy matrix;
Step (3): inlaid solid lubrication material, solid lubricant is graphite, the graphite that processing matches with the shape size in the hole on copper alloy matrix, with glue, graphite is inlayed in hand-hole, and the mosaic area of graphite is the 20%-35% of the surface area of copper alloy matrix Relative friction motion;
Step (4): to the Surface Machining of solid lubricant.
The mosaic area of graphite is the 25%-30% of the surface area of copper alloy matrix Relative friction motion, farthest can give play to the advantage of graphite during use.
Apply the production technology of a kind of mechanical wearing piece provided by the present invention, its beneficial effect is: copper alloy and graphite material have had respective complementary advantage, copper alloy and graphite have had respective advantage after bonding, have the high strength of Copper substrate concurrently, heat conduction is fast, the excellent properties such as good conductivity and the excellent lubrication antifriction performance of graphite, both bearing capacity had been possessed, breach again the boundary that general bearing relies on oil film grease lubrication, achieve oil-free lubrication, very large improvement result is served to friction and wear behavior, stability is high, automobile industry can be widely used in, die industry places machinery and automation equipment industry.
