Abstract
The utility model discloses a kind of thrust bearing shoe valve, the thrust bearing shoe valve is formed using the forging of CuZn40Al2 aldubras material, by an external diameter be 740mm, internal diameter be 660mm, highly for the cylinder of 615mm is constituted, thrust bearing shoe valve of the present utility model has high intensity, wearability good, product tissue tight, refinement, without loose and coarse grains phenomenon.
Description
Technical field
The utility model is related to field of mechanical technique, more particularly, to a kind of thrust bearing shoe valve.
Technical background
Aluminium in aldubra can improve the intensity and hardness of brass, improve corrosion stability in an atmosphere, and aldubra is used to make
Anti-corrosion part is made, is mainly used in the bearing shell materials such as Nonlubricated bearing thrust pad, traditional tin bronze, ledrite, lead antimony tin copper
Material, polynary complex al-brass is widely used in machinery industry, automobile industry etc. and is difficult bearing and axle sleeve for lubricating and changing etc.
Position.But these strengths of materials are low, wear no resistance, it is impossible to meet domestic export enterprise and made the transition to high-end equipment, capture country
Market needs, and my company launches research and production work for this project.
Utility model content
Technical problem to be solved in the utility model is directed to above-mentioned technical problem, there is provided one kind has high intensity
And the good thrust bearing shoe valve of wearability.
Technical problem to be solved in the utility model can be realized using following technical scheme：A kind of thrust bearing shoe valve, should
Thrust bearing shoe valve is formed using the forging of CuZn40Al2 aldubras material, is 740mm by an external diameter, and internal diameter is 660mm, is highly 615mm
Cylinder constitute.
Due to using technical scheme as above, the beneficial effects of the utility model to be：The utility model thrust bearing shoe valve has
High intensity, wearability are good, product tissue tight, refinement, without loose and coarse grains phenomenon.
Brief description of the drawings
Fig. 1 is a kind of structural representation of thrust bearing shoe valve of the utility model.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
A kind of thrust bearing shoe valve 100 shown in Figure 1, the thrust bearing shoe valve 100 is using the forging of CuZn40Al2 aldubras material
Into, by an external diameter be 740mm, internal diameter be 660mm, highly for the cylinder of 615mm is constituted.
A kind of manufacture method of thrust bearing shoe valve, comprises the following steps：
1st, brass melting technique：The microalloy element of cathode copper, fine aluminium, electrolytic manganese, electrolytic zinc, tinplate and high-purity,
Without greasy dirt, no moisture, free from admixture, the dissolution characteristics by Mn, Fe in brass determine its addition sequence, zinc and aluminium to all dispensings
Fusing point it is very low, and be easily oxidized, add aluminium, zincode to be easily oxidized when alloy solution temperature is higher and burn, therefore adopt
Add cold burden to be lowered the temperature with after Mn, Fe dissolve, add aluminium, the mode of zinc is produced.Due to the solid solution of Al and Zn in Cu
Degree is larger, it is easy to be dissolved in copper, it is ensured that the chemical composition of alloy.The zinc equivalent coefficient of aluminium is at a relatively high (n=6), on a small quantity
Aluminium the β phases of two-phase brass can just increased.
Copper Cu：55.5~59.0 zinc Zn：Surplus lead Pb：0~0.8 aluminium Al：1.3~2.3 iron Fe：0~1.0 manganese Mn：1.0~
2.4 nickels：0~2.0 silicon Si：0~0.8 tin Sn：0~0.5 impurity summation (other)：≤0.5
For cost-effective, improve production efficiency, the melting by the way of element is directly added into, its melting difficulty is high,
Fusion temperature is controlled at 1230-1300 DEG C.High speed centrifugation casting machine, rotating speed are used during casting：4000 revs/min, cast temperature
Control is at 1140-1230 DEG C.
2nd, ultrasonic examination, is visited using the copper alloy defect detection on ultrasonic basis of international advanced DIN 17660 to casting ring
Triage is looked into, it is to avoid cast-internal has layering, stomata, crackle and slag inclusion, and the inherent quality stabilization of product is effectively ensured.
Have high intensity, wearability good by the thrust bearing shoe valve obtained after above-mentioned steps treatment, product tissue tight, refinement,
Without loose and coarse grains phenomenon.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, the utility model can also on the premise of the utility model spirit and scope are not departed from
There are various changes and modifications, these changes and improvements are both fallen within the range of claimed the utility model.The utility model will
Protection domain is asked to be defined by appending claims and coordinate.
