Description

Technical Field

[0001] The utility model relates to the technical field of alloy steel castings, in particular to a high-strength heat-resistant alloy steel casting. Background Art

[0002] A casting is a metal-shaped object obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling and subsequent processing such as grinding, the object with a certain shape, size and performance is obtained; Patent No. CN202020628382.3 announced a high-strength alloy steel casting for intercity rail engineering. By setting a Teflon coating, the surface of the casting has excellent acid resistance, alkali resistance, corrosion resistance, and is not easy to wear or rust, which can greatly increase the service life of the casting, thereby greatly increasing the replacement cycle of the casting; However, since the hole at the top of the alloy steel casting is connected to the bolt, a large pressure will be generated between the two, and a large friction force will also be generated, which will cause the hole at the top of the alloy steel casting to wear faster, and shorten the replacement cycle of the steel casting. At the same time, in the case of severe damage, the steel casting itself can only be replaced. To this end, we propose a high-strength heat-resistant alloy steel casting. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a high-strength heat-resistant alloy steel casting.

[0004] The technical solution adopted by the utility model to solve the technical problem is a high-strength heat-resistant alloy steel casting, comprising a casting body, a concave hole for connection is provided on the top surface of the casting body, and a gasket ring body for auxiliary support is embedded in the inner side of the concave hole, a ring groove for connection is provided in the inner side of the gasket ring body, and a snap ring seat snapped with the ring groove is mounted on the bottom surface of the gasket ring body;

[0005] The inner peripheral surface of the concave hole is provided with arc grooves for connection, and there are multiple groups of arc grooves. The outer peripheral surface of the gasket ring body is integrally constructed with arc blocks that fit and connect with the arc grooves, and there are multiple groups of arc blocks.

[0006] By adopting the above technical solution, when the alloy steel casting is used, the gasket ring body can be conveniently heated and embedded into the inner side of the concave hole at the top of the casting body, and then the snap ring seat is heated so that the snap ring seat can be snapped into the inner side of the gasket ring body and can be snapped into the ring groove, so that the gasket ring body can be firmly snapped into the concave hole, and then the pressure and friction generated when the casting body and the bolt are connected to each other can be conveniently applied to the gasket ring body. When the gasket ring body is greatly worn, the gasket ring body can be directly replaced, which is convenient for saving resource consumption;

[0007] When the gasket ring body and the recessed hole are embedded in each other, the arc block and the arc groove are fitted and connected with each other, which is convenient for improving the stability of the gasket ring body after connection, so that the gasket ring body will not rotate after being embedded in the recessed hole, so that the gasket ring body and the retaining ring seat can operate more stably.

[0008] Specifically, the outer peripheral surface of the casting body is coated with a support layer for improving strength.

[0009] By adopting the above technical solution, the support layer can form a protective layer on the periphery of the casting body, so as to support the coating sprayed subsequently.

[0010] Specifically, the outer peripheral surface of the support layer is coated with a corrosion-resistant layer, and the outer peripheral surface of the corrosion-resistant layer is coated with a Teflon layer.

[0011] By adopting the above technical solution, the corrosion-resistant layer and the Teflon layer cooperate with each other, which makes it easy to improve the oxidation resistance and strength of the casting body, so that the casting body can operate more stably.

[0012] Specifically, the outer peripheral surface of the Teflon layer is coated with a wear-resistant layer.

[0013] By adopting the above technical solution, the wear-resistant layer can improve the friction resistance of the casting body, so that the strength of the casting body is improved.

[0014] Specifically, the gasket ring body and the snap ring seat are both in a T-shaped structure.

[0015] By adopting the above technical solution, the gasket ring body and the snap ring seat of the T-shaped structure can be connected to each other, so as to facilitate the protection of the concave hole on the top of the casting body.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application, through the design of the recessed hole, the gasket ring body, the ring groove and the retaining ring seat, can conveniently heat the gasket ring body and embed it into the inner side of the recessed hole on the top of the casting body when using the alloy steel casting, and then heat the retaining ring seat so that the retaining ring seat can be snapped into the inner side of the gasket ring body and can be snapped into the ring groove with each other, so that the gasket ring body can be firmly snapped into the recessed hole, and then the pressure and friction force generated when the casting body and the bolt are connected to each other can be conveniently applied to the gasket ring body. When the gasket ring body is severely worn, it can be directly replaced, which is convenient for saving resource consumption.

[0018] 2. The technical solution of the present application adopts the design of arc groove and arc block. When the gasket ring body and the recessed hole are interlocked with each other, the arc block and the arc groove are fitted and connected with each other, which is convenient for improving the stability of the gasket ring body after connection, so that the gasket ring body will not rotate after being embedded in the recessed hole, and the gasket ring body and the retaining ring seat can operate more stably.
