Description

Technical Field

[0001] The utility model relates to the technical field of ring forgings, and more specifically, to a high-temperature alloy ring forging. Background Art

[0002] High-temperature alloys refer to high-temperature metal materials that work for a long time at temperatures above 760-1500℃ and under certain stress conditions. They have excellent high-temperature strength, good oxidation resistance and thermal corrosion resistance, good fatigue performance, fracture toughness and other comprehensive properties. Therefore, ring forgings made of high-temperature alloys can be used as hot-end components of mechanical equipment.

[0003] At present, the existing alloy ring forgings need to be connected with other workpieces by fastening bolts. During long-term use, the fastening bolts will become loose due to vibration, resulting in an unstable connection between the ring forging and the other workpieces. In order to improve the stability performance, the staff adds a clamping plate at the threaded hole position on the alloy ring forging, that is, the clamping plate is used to fill the gap between the fastening bolt and the ring forging to keep the fastening bolt stable. However, the clamping plate only fills the gap between the fastening bolt and the ring forging, and the head of the fastening bolt is exposed. The problem of loosening caused by thread withdrawal is still serious, and the connection stability of the alloy ring forging and other workpieces is still poor. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a high-temperature alloy ring forging.

[0005] To achieve the above objectives, the utility model provides the following technical solutions: a high-temperature alloy ring forging, comprising a main body component and a first positioning component and a second positioning component connected to the outer wall of the main body component, wherein the first positioning component and the second positioning component are symmetrically arranged.

[0006] The main body component includes a top ring arranged in an annular shape and a bottom ring integrally formed at the bottom end of the outer wall of the top ring, and the first positioning component and the second positioning component are both integrally formed at the outer wall of the top ring.

[0008] The utility model is further configured as follows: the second positioning assembly includes a positioning block integrally formed on the outer side wall of the top ring, the positioning block is arranged at a position symmetrical to the outer side wall of the top ring and the L-shaped plate, a second positioning groove is provided on the side of the side wall of the positioning block away from the top ring, the second positioning groove passes through to the bottom surface of the positioning block, an opening is provided on the top of the positioning block, and a connecting piece is integrally formed on the top of the positioning block and away from the top ring.

[0009] The utility model is further configured as follows: a positioning stopper is integrally formed on the inner side wall of the positioning block and close to the top ring, and a gap is provided between the positioning stopper and the inner bottom wall of the positioning block.

[0010] The fastening bolt inside the first positioning groove is blocked from loosening by the limit stopper, while the fastening bolt inside the second positioning groove is blocked from loosening by the positioning stopper, thereby alleviating the loosening of the fastening bolt due to thread withdrawal and improving the connection stability between the alloy ring forging and other workpieces.

[0011] The utility model is further configured as follows: the positioning stopper is configured in a wedge shape, and one end of the positioning stopper away from the top ring extends to above the second positioning groove.

[0012] The utility model is further configured as follows: the limit stopper is configured in a wedge shape, and one end of the limit stopper away from the top ring extends to above the first positioning groove.

[0013] By adopting the above technical solution, the top surfaces of the positioning block and the limit block continue to extend along the bending direction of the external arc-shaped portion, thereby avoiding the situation where the positioning block forms a bulge upward on the top of the top ring. The utility model is further configured as follows: a built-in inclined portion is provided on the top of the inner side wall of the top ring, and an external arc-shaped portion is provided on the top of the outer side wall of the top ring.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] (1) When the ring forging is installed with the fastening bolt, the head of the fastening bolt is blocked by the limit stopper. When the bolt is loosened, it is blocked by the limit stopper to assist in limiting the position. The bolt loosening stroke is reduced, thereby improving the connection stability of the ring forging.

[0016] (2) The fastening bolt inside the second positioning groove blocks the loosening stroke through the positioning block, thereby alleviating the loosening of the fastening bolt due to thread withdrawal and improving the connection stability between the alloy ring forging and other workpieces.

DETAILED DESCRIPTION

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0025] For example, see Figure 1 and Figure 3 A high-temperature alloy ring forging includes a main body component 1 and a first positioning component 2 and a second positioning component 3 connected to the outer wall of the main body component 1. The first positioning component 2 and the second positioning component 3 are symmetrically arranged. The first positioning component 2 and the second positioning component 3 cooperate to improve the stability of the connection between the main body component 1 and other workpieces. The specific structure of the main body component 1 is as follows:

[0026] See also Figure 1-Figure 4 The main component 1 includes a top ring 12 arranged in an annular shape, a built-in inclined portion 14 is opened at the top of the inner side wall of the top ring 12, an external arc portion 13 is opened at the top of the outer side wall of the top ring 12, a bottom ring 11 is integrally formed at the bottom end of the outer wall of the top ring 12, the first positioning component 2 and the second positioning component 3 are both integrally formed on the outer side wall of the top ring 12, the top ring 12 and the bottom ring 11 cooperate to form the main structure of the high-temperature alloy ring forging, this main structure is used to connect with other workpieces, and the bottom ring 11 is located between the top ring 12 and the other workpieces.

[0027] See also Figure 1-Figure 4In this embodiment, the first positioning assembly 2 includes an L-shaped plate 21 integrally formed on the outer wall of the top ring 12 and a first positioning groove 23 opened on the side wall of the L-shaped plate 21. The first positioning groove 23 is used to place a fastening bolt, that is, the head of the fastening bolt is placed inside the L-shaped plate 21, and the screw portion of the fastening bolt is passed through the inside of the first positioning groove 23. Since the first positioning groove 23 passes through the bottom surface of the L-shaped plate 21, the fastening bolt directly slides horizontally into the inside of the L-shaped plate 21 through the side wall of the L-shaped plate 21.

[0028] See also Figure 2-Figure 4 A limit stopper 22 is integrally formed on the outer side wall of the top ring 12 and above the L-shaped plate 21. A gap is provided between the limit stopper 22 and the inner bottom wall of the L-shaped plate 21. The gap is used to place the head of the fastening bolt. The limit stopper 22 is wedge-shaped, and the end of the limit stopper 22 away from the top ring 12 extends to above the first positioning groove 23. The top surface of the limit stopper 22 continues to extend along the bending direction of the external arc-shaped portion 13, thereby preventing the limit stopper 22 from protruding upward on the top of the top ring 12. In addition, when the ring forging is installed using the fastening bolt, the head of the fastening bolt is blocked by the limit stopper 22. When the bolt is loosened, it is blocked by the limit stopper 22 for auxiliary limiting. The bolt loosening stroke is reduced, thereby improving the connection stability of the ring forging.

[0029] See also Figure 2-Figure 4 In this embodiment, the second positioning assembly 3 includes a positioning block 31 integrally formed on the outer wall of the top ring 12. The positioning block 31 is arranged at a position symmetrical to the outer wall of the top ring 12 and the L-shaped plate 21. A second positioning groove 33 is formed on the side wall of the positioning block 31 away from the top ring 12. The second positioning groove 33 penetrates to the bottom surface of the positioning block 31. When the ring forging is connected through the second positioning assembly 3, the fastening bolt slides into the interior of the positioning block 31 through the second positioning groove 33. The inner wall of the positioning block 31 and the position close to the top ring 12 are A positioning block 32 is formed in the body, and a gap is set between the positioning block 32 and the inner bottom wall of the positioning block 31. The positioning block 32 is set in a wedge shape, and the end of the positioning block 32 away from the top ring 12 extends to the top of the second positioning groove 33. The top surface of the positioning block 32 continues to extend along the bending direction of the external arc-shaped portion 13, thereby avoiding the positioning block 32 from forming a bulge upward on the top of the top ring 12. The head of the fastening bolt sliding into the second positioning groove 33 is limited by the positioning block 32 to reduce the bolt loosening stroke.

[0030] See also Figure 2-Figure 4 An opening is provided at the top of the positioning block 31, and a connecting piece 34 is integrally formed at the top of the positioning block 31 and away from the top ring 12. In addition, the connecting piece 34 cooperates with the positioning stopper 32 to also block the tightening bolts.

[0031] Specifically, the staff first places the fastening bolts through the first positioning groove 23 and the second positioning groove 33, and then aligns the ring forging with other workpieces. After the alignment is completed, the staff tightens the fastening bolts inside the first positioning groove 23 and the second positioning groove 33, and finally completes the stable connection between the ring forging and other workpieces. The fastening bolts inside the first positioning groove 23 are blocked from loosening by the limit stop 22, and the fastening bolts inside the second positioning groove 33 are blocked from loosening by the positioning stop 32, thereby alleviating the loosening of the fastening bolts due to wire withdrawal, and improving the stability of the connection between the alloy ring forging and other workpieces.

[0032] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
