Description
Technical field
The present invention relates to a kind of manufacture method of composite bearing, relate in particular to a kind of manufacture method of once sintered bimetallic bearing.
Background technique
Traditional sliding bearing is all to cast axle sleeve with the Cuprum alloy cast mostly, forms through cutting again, and such structure manufacture cost height, particularly along with the rise of nonferrous metal price, the copper/copper alloy bearing of this integral body is known as bimetallic bearing and substitutes.The manufacture method of present bimetallic bearing is to be matrix with the steel plate, spreads copper alloy powder equably on the surface of steel plate, and makes it have certain spreading thickness; Carry out then once sintered so that copper alloy powder is bonded on the steel plate; Carry out once more rolling so that the copper alloy layer compactly extruding; Then carry out double sintering, so that copper alloy layer is bonded on the steel backing securely; Carry out reroll at last, with the size of accurate control bimetal plate; Final production goes out to meet the copper-steel bimetal bearing material of required size requirement, and wherein number of patent application be 200510110718.7 phosphorus content greater than phosphor bronze-steel bimetal bearing material manufacturing process of 0.1% is exactly to come production of copper-steel bimetal bearing material with such technology.The manufacturing of bimetallic bearing generally is: according to the size of bimetallic bearing with blank under copper-steel bimetal bearing material → roll blank circular → with the finished product of proofreading and correct cover and the plug correction → axle sleeve cutting is reached bimetallic bearing require → check → pack warehouse-in.Need through twice sintering, twice rollingly in the production of copper-steel bimetal bearing material, complex process, energy consumption are big, the manufacture cost height, manufacture cycle is long, also contain harmful matters such as lead, phosphorus in some Cuprum alloys, when repeatedly sintering heats, environment is on every side polluted.
Summary of the invention
The object of the present invention is to provide that a kind of technology is simple, energy consumption is little, low cost of manufacture, short once sintered bimetallic bearing manufacture method of cycle.
In order to achieve the above object, once sintered bimetallic bearing manufacture method is: it includes the following step successively: surface of steel plate spread equably the sheet material of copper alloy powder sintering → make copper-steel bimetal bearing material → according to the size of bimetallic bearing with the sheet material of copper-steel bimetal bearing material under blank → roll blank become axle sleeve → usefulness of circular to proofread and correct the inner and outer surface that cover and plug push axle sleeve, proofread and correct the endoporus of axle sleeve and cylindrical size → to the axle sleeve cutting, the finished product that reaches bimetallic bearing requires → checks → packs, puts in storage.
According to above-mentioned once sintered bimetallic bearing manufacture method, in the sheet material manufacture process of copper-steel bimetal bearing material, it has only used once sintered, more rolling than original twice sintering, twice, saved once sintered and twice rolling, make the control of size, in the end when proofreading and correct cover and plug and push the inner and outer surface of axle sleeve, make the size of the endoporus of axle sleeve and cylindrical and operation that being squeezed in of copper alloy layer proofreaied and correct later in once finish.Technology is simplified greatly, and the versatility of equipment is good, and the technology inheritance is good, has saved sintering and the rolling energy that consumes, labour force and manufacture cost, and the quality of product is still same to be guaranteed, is beneficial to the protection of environment again.
