Abstract
Description
Technical Field
[0001] This utility model relates to the field of blowout preventer manufacturing and processing technology, specifically a tooling for manufacturing and processing blowout preventer rubber cores. Background Technology
[0002] A blowout preventer (BOP) is a sealing device used to close the wellhead during operations such as well testing, well workover, and well completion to prevent blowout accidents. BOP manufacturing refers to the process of manufacturing and processing the BOP. It is mainly used to close the wellhead during operations such as well testing, well workover, and well completion to prevent blowout accidents. In the production of BOPs, a series of processing steps such as grinding, cutting, and perforating are required to process the rubber core into the required shape and size.
[0003] During the processing of blowout preventer cores, the cores are prone to tilting or shaking, which may cause deviations in the processing position, deformation and damage to the cores themselves, affecting processing efficiency. Furthermore, the cores cannot be flipped or moved during processing, resulting in poor processing flexibility. Utility Model Content

[0014] 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.
[0015] Example: Figure 1-3As shown, this utility model provides a tooling for manufacturing blowout preventer cores, including a base frame 1. A clamping device 2 is rotatably mounted on the upper surface of one side of the base frame 1. The clamping device 2 includes an upper support plate 21 and a lower support plate 22. A cylinder 23 is fixedly mounted on the lower surface of the upper support plate 21, and the output end of the cylinder 23 is fixedly connected to the upper surface of the lower support plate 22. Four second slide rails 24 are fixedly mounted on the upper surface of the upper support plate 21. Second sliders 25 are slidably sleeved on the upper surface of the second slide rails 24. A first connecting plate 26 is fixedly mounted on the upper surface of the second sliders 25. A clamping plate 27 is fixedly mounted on the upper surface of the first connecting plate 26. A second connecting plate 28 is rotatably connected to the side of the connecting plate 26 facing the lower support plate 22. One side of the second connecting plate 28 is rotatably connected to the upper surface of the lower support plate 22. Support shafts 29 are fixedly connected to both sides of the upper support plate 21. The lower support plate 22 can be subjected to a downward force by the output of the cylinder 23. As the lower support plate 22 moves downward, it drives the four second connecting plates 28 to rotate. The rotational force drives the four first connecting plates 26 and the clamping plates 27 to slide synchronously in a straight line along the second slide rail 24 through the second slider 25, thereby completing the self-centering clamping motion process of the four clamping plates 27.
[0016] The upper surface of the base frame 1 is fixedly mounted on both sides of the first slide rail 11. Four first sliders 12 are slidably sleeved on the upper surface of each of the first slide rails 11. Two support seats 14 are fixedly mounted on the upper surface of each of the four first sliders 12. Two shaft seats 16 are fixedly mounted on the upper surface of each support seat 14. Two shaft seats 16 located on the same side are rotatably sleeved with two support shafts 29. A reduction motor 15 is fixedly mounted on the upper surface of one of the support seats 14. The output end of the reduction motor 15 is fixedly connected to one end of one of the support shafts 29. The operator can... The output drives the upper support plate 21 in the clamping device 2 to rotate under the connection of two support shafts 29. The support base 14 with a certain height allows the clamping device 2 to rotate freely without restriction. By pushing the push rod 17 on one side, the two support bases 14 are driven to slide linearly along the two first slide rails 11. The four limiting plates 18 and limiting pins 19 at both ends of the two first slide rails 11 help limit the movement distance of the first slider 12 during the movement process, which helps the operator to rotate and move when processing the rubber core, and improves the flexibility of rubber core processing.
[0017] The clamping plates 27 are arranged in a ring array and are L-shaped. The second connecting plates 28 are also arranged in a ring array, and all four second connecting plates 28 are set at an inclined angle. Four limiting plates 18 are fixedly installed on the upper surfaces of both sides of the base frame 1. A limiting pin 19 is fixedly inserted into one side of the limiting plate 18. The four limiting pins 19 are respectively distributed at both ends of the two first slide rails 11. The bottom end of the base frame 1 is fixedly installed with four support legs by bolts, and the four support legs are arranged in a rectangular array. The four clamping plates 27 arranged in a ring array can ensure the clamping force of the four clamping plates 27. To maintain consistency, the rubber cores between the four clamping plates 27 are automatically calibrated. The four inclined second connecting plates 28 can apply the same force to the four first connecting plates 26 synchronously as the lower support plate 22 moves. The larger the inclination angle, the greater the applied rotational force. The four mirror-distributed limiting pins 19 are distributed on both sides of the two first slide rails 11, providing a specified distance movement limit for the four first sliders 12, preventing the first sliders 12 from rushing out of the first slide rails 11. The four support legs provide stable support for the base frame 1, ensuring the stability and balance of the base frame 1.
[0018] Push rods 17 are fixedly connected to one side of the upper surface of the two first sliders 12. The support seats 14 are distributed in a mirror image. The operator can push the push rods 17 to drive the two support seats 14 to move linearly with the help of the first sliders 12 and the first slide rails 11. The two mirror-distributed support seats 14 will provide a certain support height for the clamping device 2, so that the clamping device 2 is unrestricted during the flipping process.
[0019] Working principle: When it is necessary to clamp and fix the rubber core, place the rubber core on the four clamping plates 27, and then start the cylinder 23. The output end of the cylinder 23 drives the lower support plate 22 to push downward. The moving lower support plate 22 drives the four second connecting plates 28 to rotate synchronously. Under the rotation of the four second connecting plates 28, the first connecting plate 26 is driven to slide linearly along the outer surface of the second slide rail 24 with the help of the second slider 25. The four sliding second sliders 25 drive the four clamping plates 27 to perform clamping movement with the center point of the upper support plate 21 as the center, thereby clamping and fixing the bottom end of the rubber core in four directions.
[0020] When it is necessary to flip the rubber core, the reduction motor 15 at the top of the support base 14 is started. The reduction motor 15 drives one of the support shafts 29 to rotate through the output, so that the clamping device 2 flips under the connected rotation of the two support shafts 29. When it is necessary to move, the operator can push the push rod 17 to make the two support bases 14 move linearly along the two first slide rails 11 with the help of the first slider 12, so as to achieve the purpose of flipping and moving the rubber core clamped in the clamping device 2.
[0021] 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.
