Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a forging flange with high strength and anti-deformation. Background Technique

[0002] The forging flange is a kind of flange product with the best mechanical properties. Its raw material is generally a pipe blank, which is then cut and continuously hammered to eliminate defects such as segregation and porosity in the ingot. Forging can improve the density and mechanical properties of the metal, making the flange have higher strength and durability. The forging flange is suitable for occasions with high pressure, high temperature and high strength requirements, such as the fields of petrochemical industry, shipbuilding, nuclear power, etc. The main materials of the forging flange include carbon steel, alloy steel and stainless steel. The forging flange has good pressure resistance and temperature resistance, and is generally suitable for high-pressure and high-temperature working environments. At present, the forging flanges applicable to the market still have some disadvantages;

[0003] The existing forging flanges will cause the flange to deform and the paint to fall off under the action of external forces, which will lead to damage to the flange. At the same time, the flanges are all welded together integrally, making it difficult to disassemble. For example, the Chinese utility model patent with the authorization announcement number CN219345798U discloses a forging flange, including a flange structure, a connecting device and a fastening structure. The middle part of the flange structure is connected with a connecting device, and the middle part of the connecting device is connected with a fastening structure. When in use, the connecting pipe is inserted into the connecting groove to connect two groups of flange pipes, and at the same time, the limiting rod is inserted into the limiting groove. Then, the right flange pipe is rotated to fix the limiting rod in the limiting groove, and at the same time, the holes of the two groups of flange plates are aligned. The inserting rod is inserted into the flange plate, and then the nut is screwed into the first thread groove for fixation. Then, the slide plate is placed in the chute to fit the nut, and then the bolt is screwed into the second thread groove to make the slide plate close to the nut for fixation, so that the connection of the flange is more tightly and stably, improving the practicability of the device. However, this device will cause the flange to deform and the paint to fall off under the action of external forces, which will lead to damage to the flange. At the same time, the flanges are all welded together integrally, making it difficult to disassemble and assemble. In addition, the flange and the flange column are connected by threads, and it is easy to fall off and other problems. Therefore, we propose a forging flange with high strength and anti-deformation to facilitate the solution of the problems raised above. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-5 , the present utility model provides a technical solution: a high-strength anti-deformation forged flange, comprising: a first flange body 1, a second flange body 2, a fixing hole 3, a rubber pad 4, a card slot 5, a buffer pad 6, a first protection block 7, a second protection block 8, a lower clamping block 9, a flange column 10, a gear block 11, a clamping block 12, a fixing block 13, a screw 14, a support frame 15 and an upper clamping block 16;

[0027] Such as Figure 1 , Figure 2 And Figure 3As shown in the figure, fixing holes 3 are evenly arranged at equal angles inside the first flange body 1 and the second flange body 2. By using fixing bolts and inserting them into the fixing holes 3 and tightening them, the first flange body 1 and the second flange body 2 can be fixed. At the same time, rubber pads 4 are closely attached to the outer sides of the first flange body 1 and the second flange body 2. The rubber pads 4 can protect the outer sides of the first flange body 1 and the second flange body 2. In addition, clamping grooves 5 are opened at equal angles on the inner sides of the rubber pads 4, and buffer pads 6 are clamped inside the clamping grooves 5. The buffer pads 6 can reduce the deformation of the first flange body 1 and the second flange body 2 caused by external forces. Secondly, the buffer pads 6 are also clamped inside the second protective block 8 and the first protective block 7. The second protective block 8 and the first protective block 7 are respectively arranged on the front and back sides of the rubber pad 4. The second protective block 8 and the first protective block 7 are clamped and connected together. The inner rubber pad 4 is also clamped on the outer sides of the first flange body 1 and the second flange body 2. Secondly, upper clamping blocks 16 are arranged on the left and right sides inside the second protective block 8, and lower clamping blocks 9 are arranged on the left and right sides inside the first protective block 7. After the second protective block 8 and the first protective block 7 are clamped together, the lower clamping blocks 9 and the upper clamping blocks 16 will be closely attached to each other up and down. Then, the screws 14 are inserted into the lower clamping blocks 9 and the upper clamping blocks 16, and the rubber pad 4, the second protective block 8 and the first protective block 7 can be firmly fixed on the outer sides of the first flange body 1 and the second flange body 2;

[0028] As Figure 1 , Figure 4 and Figure 5 shown in the figure, the inner parts of the first flange body 1 and the second flange body 2 are both threadedly connected to the flange column 10. To ensure the stability of the connection between the first flange body 1 and the second flange body 2 and the flange column 10, that is, the support frames 15 rotatably installed on the outer sides of the first flange body 1 and the second flange body 2 are rotated. Clamping blocks 12 are fixedly installed inside the upper and lower sides of the support frames 15, and gear blocks 11 are arranged inside the clamping blocks 12. After the first flange body 1 and the second flange body 2 are threadedly connected to the flange column 10, when the support frames 15 rotatably installed on the outer sides of the first flange body 1 and the second flange body 2 are rotated inward at the same time, the clamping blocks 12 and the gear blocks 11 will be rotated inward at the same time, that is, the gear blocks 11 will be firmly attached to the flange column 10. The setting of the gear blocks 11 can increase the friction force between the flange column 10 and the clamping blocks 12. Secondly, fixing blocks 13 are symmetrically installed on the front and back sides of the clamping blocks 12, and the fixing blocks 13 can be fixed by using screws 14. In this way, the gear blocks 11 and the clamping blocks 12 can be firmly clamped and fixed on the outer side of the flange column 10, increasing the stability of the connection between the first flange body 1 and the second flange body 2 and the flange column 10;

[0029] As Figure 1As shown in the figure, the first flange body 1 and the second flange body 2 are fixed by fixing bolts. As long as the fixing bolts are unscrewed, the first flange body 1 and the second flange body 2 can be separated. At the same time, the rubber pads 4, the second protective blocks 8 and the first protective blocks 7 on the outer sides of the first flange body 1 and the second flange body 2 are all snap-connected together and fixed by screws 14. That is, by unscrewing the screws 14, the rubber pads 4, the second protective blocks 8 and the first protective blocks 7 can be removed from the outer side of the first flange body 1. In addition, the gear blocks 11 and the clamping blocks 12 on the outer side of the flange column 10 are also fixed by screws 14. That is, by unscrewing the screws 14, the flange column 10 will also be separated from the gear blocks 11 and the clamping blocks 12. That is, once a component in the first flange body 1 or the second flange body 2 has a problem, it is convenient to replace it.
