Abstract
The invention relates to manufacture of a metal plate, in particular to an environment-friendly copper base-steel bimetal shaft bushing material and a manufacturing method thereof. The invention adopts a technical proposal that the material consists of a steel plate and a copper base alloy abrasion-resistant layer, wherein the copper base alloy abrasion-resistant layer comprises the following components in percentage by weight: 1 to 15 percent of bismuth, 0.5 to 10 percent of tin, 0.3 to 15 percent of zinc, and the balance being copper; and the copper base alloy abrasion-resistant layer is directly sintered or poured on the steel plate. The material and the method have the advantages that because the bismuth is used for replacing lead in the copper base alloy, the material does not contain the lead, has no harm to human body or pollution to environment, and is the environment-friendly copper base-steel bimetal shaft bushing material.
Description
Technical field
The present invention relates to the manufacturing of sheet metal, especially belong to environment protection type copper base-bimetal copper-steel bush material and manufacture method thereof.
Technical background
Copper base-bimetal copper-steel bush material is that sintering or casting one deck copper base alloy form on copper coating (main purpose be in order to prevent get rusty) or not copper-plated steel plate, is the basic material that various motor car engines, diesel engine etc. are gone up widely used various bearing shells, flanger bearing liner, bearing, axle bush, axle sleeve.The copper base alloy of traditional copper base-bimetal copper-steel bush material is made up of copper, lead, tin, zinc (or phosphorus), owing to contain lead, toxic to human body, environment there is pollution, therefore reduce gradually recently and use.Regulation in European Union's " some harmful matter is used in restriction in electric, the electronic equipment ", from July 1st, 2006, the new electronics and the electrical equipment that devote market must not contain harmful matters such as lead.Simultaneously; along with people to improving day by day of environmental protection consciousness and self health requirements and popularizing of mechanization traffic, production and daily life instrument; people recognize the pollution to people and environment of refuse that various tool in use produced; people wish that the various parts of institute's tool using all are environmentally friendly machines; therefore, seeking lead in the copper base alloy that a kind of nontoxic constituent element replaces traditional manufacturing bush material, to become development inevitable.
Summary of the invention
The object of the present invention is to provide a kind of environment protection type copper base-bimetal copper-steel bush material and manufacture method thereof of using bismuth, make the bush material of producing not contain harmful compositions such as lead.
The technical solution used in the present invention is that it is made up of steel plate and copper base alloy wearing layer; Wherein, the prescription of copper base alloy wearing layer composition is by weight percentage: bismuth 1%～15%, tin 0.5%～10%, zinc 0.3%～15%, surplus are copper; And the copper base alloy wearing layer is direct sintering or casts on the steel plate.
Usefulness of the present invention is: owing to replace lead with bismuth in the copper base alloy, not leaded, to the human body nonhazardous, environmentally safe is a kind of environment protection type copper base-bimetal copper-steel bush material.Simultaneously, the density of bismuth is littler than plumbous, and the bush material of manufacturing is lighter than leaded.
