Description

Technical Field

[0001] This utility model relates to the field of metal forging technology, specifically to a pressure valve body forging equipment used in oil extraction. Background Technology

[0002] Pressure valves are key components in oil drilling and production equipment, primarily used to control and regulate the pressure, flow rate, and direction of fluids (such as crude oil, natural gas, and drilling fluid) in the well, ensuring safe and efficient operations. Due to the complex environment of oil extraction, pressure valves must withstand high pressure, high temperature, and corrosive media. Forging processes can significantly improve the comprehensive performance of high-strength alloy steel. The forging process involves heating the metal block at high temperature until it reaches the metal's crystallization temperature. The specific temperature varies depending on the material. High temperatures increase the plasticity of the metal, and then the metal is continuously hammered by forging equipment to produce products with corresponding structures.

[0003] However, when forging pressure valve bodies for oil extraction, the pressure valves need to withstand high pressure, high temperature, and corrosive media. The temperature during forging is typically between 1000℃ and 1200℃, which easily leads to the formation of oxide scale on the metal surface. The impact force applied by the forging hammer or press causes this oxide scale to flake off and fall onto the forging table. If not cleaned promptly, the oxide scale will be squeezed into the metal surface during forging, forming pits, pinholes, and other defects, resulting in a rough surface, reduced appearance quality and dimensional accuracy, and in severe cases, scrapping the forging. Traditional oil valve body forging equipment mainly relies on manual shoveling or compressed air blowing after shutdown for waste removal. However, manual operation in high-temperature environments can easily cause burns and is inefficient. Using compressed air for blowing can easily cause waste to splash, polluting the environment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1-7 As shown, this utility model provides a pressure valve body forging equipment for oil exploration, including a base plate 1. A forging press 3 is fixedly installed on the top of the base plate 1, and a forging table 2 is fixedly installed in the middle of the top of the base plate 1. Two symmetrically distributed fixed shells 24 are fixedly installed on the upper part of the forging table 2. A frame 26 is provided in the middle of the opposite side of the two fixed shells 24. Scrapers 261 are detachably provided on both sides of the lower part of the frame 26. The lower parts of the two scrapers 261 are in contact with the top of the forging table 2.

[0023] A reciprocating screw 23 is rotatably mounted on the middle of one side of one of the fixed housings 24. A drive assembly is provided on one side of the reciprocating screw 23. A sliding block 231 that works in conjunction with the reciprocating screw 23 is mounted on the upper part of the reciprocating screw 23. Mounting plates 25 are fixedly mounted on both ends of the frame 26. One side of one of the mounting plates 25 is fixedly mounted on one side of the sliding block 231.

[0024] A cleaning roller 272 is rotatably mounted in the middle of the frame 26. A gear 27 is fixedly mounted at one end of the cleaning roller 272 through the mounting plate 25. A toothed plate 271 is fixedly mounted on one side of the upper part of another fixed shell 24. The gear 27 and the toothed plate 271 are meshed and connected to each other.

[0025] One of the fixed housings 24 is fixedly mounted with a protective cover 221 on one side. By setting the protective cover 221, the metal oxide scale can be isolated from the outside, reducing the wear on its drive components.

[0026] The drive assembly includes a motor 22, which is fixedly installed inside the protective cover 221. One end of the reciprocating lead screw 23 is fixedly installed on the drive end of the motor 22. By setting the motor 22, the reciprocating lead screw 23 can be driven to rotate.

[0027] One of the fixed shells 24 has a groove in the middle, and the sliding block 231 is slidably locked inside the groove. By setting the groove, the sliding block 231 can be limited, thereby ensuring that the sliding block 231 is driven to slide back and forth when the reciprocating screw 23 rotates, instead of rotating with the reciprocating screw 23.

[0028] A limiting rod 28 is fixedly installed on the middle of one side of another fixed shell 24. A moving block 281 is slidably engaged on the outer surface of the limiting rod 28. One side of the gear 27 is rotatably installed on the middle of one side of the moving block 281. By setting the limiting rod 28, the gear 27 can be limited, ensuring that the gear 27 can mesh with the gear plate 271 while rotating.

[0029] The scraper 261 is made of cemented carbide. By setting the scraper 261, the surface temperature of the forging table 2 is high during the forging process. The cemented carbide scraper 261 has good high temperature resistance and can maintain its hardness and strength in high temperature environment. It will not soften or deform due to heat, thus ensuring the normal use of the scraper 261.

[0030] Collection boxes 21 are fixedly installed on both sides of the forging table 2. A cleaning box 211 is slidably installed through the lower part of the two collection boxes 21. By setting up the cleaning box 211, the metal oxides scraped off by the scraper 261 can be collected in a concentrated manner.

[0031] Working principle: When cleaning the oxide scale retained on the upper surface of the forging table 2, the reciprocating screw 23 is driven by the motor 22 to rotate, thereby moving the sliding block 231 that works in conjunction with it, which in turn moves the frame 26 installed on one side. This causes the scraper 261 to slide on the upper surface of the forging table 2, thereby scraping off the oxide scale generated on the surface. The metal oxide scale moves with the scraper 261 to one side of the forging table 2. Since a collection box 21 and a cleaning box 211 are set on one side of the forging table 2, the metal oxide scale that has moved to the upper part of the collection box 21 by the scraper 261 falls into the collection box 21 and enters the cleaning box 211. By pulling the cleaning box 211, it can be pulled out from one side of the collection box 21, thereby cleaning the metal oxide scale inside the collection box 21.

[0032] At the same time, the movement of the frame 26 drives the cleaning roller 272 to move. Since the gear 27 fixedly installed on one side of the cleaning roller 272 meshes with the toothed plate 271, the cleaning roller 272 rotates while moving, thereby cleaning the surface of the forging table 2 and cleaning some of the metal oxide scale attached to the surface of the forging table 2. This is done in conjunction with the scraper 261.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
