Description
Technical field
The utility model relates to a kind of centrifugal fusion casting die, and bimetallic plain thrust bearing blank mould is prepared in especially a kind of centrifugal founding.
Background technology
Steel backing Pot metal bimetallic plain thrust bearing is widely used in the products such as rolling stock, engineering machinery such as 4400 horsepower internal combustion engine cars, and its bearing capacity and mechanical property are all better than the sliding bearing of single alloy material.And the method for conventional manufacture bimetallic plain thrust bearing blank has the combination technological method of static casting method, powder sintering process and multi-step etc., because the performance difference of above-mentioned technique is larger, there is the mould of employing, also have and not adopt mould, in the technique of mould, there is sealing and adopt, also have and do not seal.In centrifugal casting technical process, because steel backing and the copper alloy of thrust surface are difficult to combination under centrifugal action, the art personnel generally believe that more difficult employing centrifugal casting or similar casting method for centrifugal prepare bimetallic plain thrust bearing blank.And in centrifugal founding preparation process for sliding bearing, steel backing often adopts steel plate sealing, connect and mainly realize by spot welding, in use procedure, often find that being tightly connected of steel backing and steel plate is bad, and because the existence of steel plate often causes conducting heat too fast and clears up difficulty, often there is crack defect in made bimetallic blank two ends.The bimetallic plain thrust bearing blank can preparation quality meeting the demands by the centrifugal casting method of eddy-current heating particle now, but in the method, need to provide the mould of a reasonable in design.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, bimetallic plain thrust bearing blank die for preparation tool that can solve bimetallic plain thrust bearing blank two ends alloy-layer and be prone to crack problem.
In order to achieve the above object, the technical solution of the utility model is: a kind of bimetallic plain thrust bearing blank die for preparation tool, comprise steel billet and asbestos board, described steel billet has endoporus and annular groove, annular groove is arranged on the hole wall of endoporus, and endoporus is communicated with annular groove, and the two ends of described steel billet are all stained with corresponding asbestos board by high temperature resistant binder, described asbestos board has centre bore, and the centre bore of asbestos board and the endoporus of steel billet are communicated with.
Described annular groove is arranged on one end away from steel billet central cross-section S1 of steel billet, and the cross section of the annular groove of described steel billet is U-shaped, and the side bead place away from steel billet central cross-section S1 of the U-shaped opening of annular groove is connected by circular arc with the inwall of steel billet.
Diameter >=the 8mm of the centre bore of described asbestos board.
Thickness >=the 2mm of described asbestos board.
The periphery of steel billet has annular protrusion, and the outer face S3 of asbestos board is apart from distance d >=10mm of the central cross-section S2 of annular protrusion.
Adopt after said structure, the utlity model has: simple in structure, the structural design of steel billet is beneficial to deslagging and meets manufacturing technique requirent, ensure the performance of bimetallic plain thrust bearing thrust surface alloy-layer, the employing of asbestos board can be avoided the problem that the heat transfer in conventional steel plate use procedure is excessive and cleaning is difficult, setting up of interstitial hole is beneficial to exhaust, solved bimetallic plain thrust bearing blank two ends alloy-layers and be prone to the production of crack defect.The rational proportion of high temperature resistant binder and use, ensured intensity and the bonds well performance in high-temperature work environment, and aluminium alloy is difficult for throwing away, and cleaning is also easier to.
Brief description of the drawings
The embodiment providing below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is the structural representation of bimetallic plain thrust bearing blank die for preparation tool of the present utility model;
