Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a processing device for anti-winding wire of oil well pipe thread. Background Technology

[0002] In the oil extraction industry, well tubing is a crucial component connecting the wellhead and downhole equipment. Its quality and reliability directly affect the normal operation and safe production of the oil well. The threaded connection of the well tubing is a critical link in the entire tubing system. During drilling, production, and subsequent maintenance, the threaded portion needs to withstand complex mechanical loads, including tension, compression, torsion, and vibration. However, in actual use, well tubing threads are prone to wear, corrosion, and loosening. These problems can lead to decreased thread sealing performance and even cause safety accidents such as well leaks. To improve the service life and sealing performance of well tubing threads, anti-winding threads are typically installed at the threaded portion. Anti-winding threads effectively prevent threads from tangling during installation and disassembly, reducing thread wear and damage, while also providing a certain degree of sealing and improving the overall performance of the well tubing.

[0003] In the process of processing anti-winding wire for oil well pipe threads, the metal wire released from the wire feeding mechanism is straightened by the straightening mechanism, and then wound around the threaded part of the oil well pipe by the winding mechanism according to a specific pitch and angle. Finally, the winding wire is fixed to the pipe body by the welding mechanism. However, the heat generated during the final welding process may cause uneven heating of the oil well pipe, resulting in pipe deformation and affecting the dimensional accuracy and performance of the oil well pipe. In particular, the welding deformation problem may be more prominent for some thin-walled oil well pipes. Therefore, this application proposes an anti-winding wire processing device for oil well pipe threads. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art that the heat generated during the welding process may cause uneven heating of the oil well pipe, leading to pipe deformation and affecting the dimensional accuracy and performance of the oil well pipe. This invention proposes an anti-winding wire processing device for oil well pipe threads.

This effectively controls the temperature rise of the oil well pipe, reduces deformation caused by uneven heating, and reduces the risk of deformation or damage to the rotating clamp due to long-term heating, thus protecting the surface quality and dimensional accuracy of the oil well pipe.

[0017] Furthermore, by setting up a turntable, rotating shaft, rotating roller, impact plate, and blades, the turntable drives the impact plate to rotate while striking the blades to make them rotate and stir together. This allows the cooling water in the water tank to be in a dynamic flow state at all times, breaking the thermal boundary layer, increasing the heat exchange coefficient between the cooling water, thereby accelerating the dissipation of heat and improving cooling efficiency.

[0018] This invention enables rapid heat conduction during welding, preventing heat accumulation in localized areas of the pipe body. This effectively controls the temperature rise of the oil well pipe, reduces deformation caused by uneven heating, and lowers the risk of deformation or damage to the rotating clamp due to prolonged heating, thus protecting the surface quality and dimensional accuracy of the oil well pipe.

[0031] Example

[0032] like Figure 1 and Figure 2As shown, the present invention proposes an anti-winding wire processing device for oil well pipe threads, including a base 1 and a straightening mechanism 2, and a wire feeding frame 3 fixedly installed on the base 1. A fixing plate 4 is fixedly installed on the wire feeding frame 3, and a metal wire reel 5 is rotatably installed on the fixing plate 4. The metal wire reel 5 releases the metal wire by rotating the shaft. A bearing is installed at one end of the shaft to allow the shaft to rotate flexibly. A tension adjustment device (not shown in the figure) is usually provided next to the wire feeding frame 3. It usually consists of one or more tension wheels and a spring. After the metal wire is led out from the metal wire reel 5, it passes through the tension wheel. The spring adjusts the tension of the metal wire by applying pressure to the tension wheel to ensure that the metal wire maintains appropriate tension during the release process and prevents slack or excessive tension.

[0033] In addition, the straightening mechanism includes multiple sets of straightening rollers and a roller drive device. The multiple sets of straightening rollers consist of several rollers arranged vertically, and the spacing between the rollers can be adjusted according to the diameter of the metal wire. After the metal wire is drawn out from the feeding mechanism, it enters the straightening roller set. The rollers apply pressure and friction to the metal wire, eliminating bending and twisting caused during storage or transportation through multiple bending and straightening processes, thus achieving a straight state. The roller drive device provides power to the straightening rollers, enabling them to rotate at a certain speed and direction, driving the metal wire to move between the straightening rollers. Generally, a motor is used to drive the rollers via belt or gear transmission; however, as this is existing technology, it will not be described in detail here.

[0034] In addition, a winding base 6 is provided on the base 1, and a metal shaft 7 is rotatably mounted on the winding base 6. A rotating clamp 8 is installed at one end of the metal shaft 7. The rotating clamp 8 is usually a three-jaw chuck or a four-jaw chuck. Figure 1 and Figure 2 The three-jaw chuck is in the middle. The metal shaft 7 is driven to rotate by a motor through a coupling. The rotating clamp 8 is used to fix the oil well pipe. The straightening mechanism 2 is installed on the base 1 and is located between the wire laying frame 3 and the winding base 6. An L-shaped fixing plate 11 is fixedly installed on the base 1 on one side of the winding base 6.

[0035] like Figures 1-3 As shown, the L-shaped fixing plate 11 is also equipped with a welding mechanism, and the winding base 6 is equipped with a winding head. The winding head is equipped with a guide wheel and a tension adjustment device. After the metal wire is led out from the straightening mechanism 2, it passes through the guide wheel of the winding head and is guided to the surface of the oil well pipe for winding. The tension adjustment device can adjust the tension of the metal wire in real time during the winding process to ensure the tightness and uniformity of the winding.

[0036] It is worth noting that a feed fixing frame 13 is fixedly installed on the base 1. A linear guide rail 14 is provided on the feed fixing frame 13. A movable seat 15 is slidably installed inside the linear guide rail 14. The movable seat 15 and the winding base 6 are fixedly connected. A lead screw 16, which is threadedly connected to the movable seat 15, is rotatably installed inside the linear guide rail 14. A drive motor 17 is fixedly installed on one side of the feed fixing frame 13. The output shaft of the drive motor 17 is fixedly connected to the lead screw 16. When the drive motor 17 is started, the lead screw 16 rotates. The movable seat 15 can drive the winding base 6 to move left or right along the linear guide rail 14. At the same time, the metal shaft 7 drives the oil well pipe fixed by the rotating clamp 8 to rotate, so that the metal wire can be wound on the threaded part of the oil well pipe according to a specific pitch and angle.

[0037] like Figures 2-4 As shown, the device also includes a cooling device, which is installed on the L-shaped fixed plate 11 to disperse and cool the heat of the rotating clamp 8. The cooling device includes a water tank 12 fixedly installed on the top of the L-shaped fixed plate 11. Water inlet pipes and drain pipes are installed at both ends of the water tank 12, and valves are installed on both the water inlet pipes and the drain pipes. Cooling medium, such as water or ethylene glycol aqueous solution, is injected into the water tank 12 through the water inlet pipe. A heat-conducting plate 19 is fixedly installed on the bottom of the inner wall of the water tank 12, and a heat dissipation plate 20 is fixedly connected to the heat-conducting plate 19. The heat dissipation plate 20, together with the cooling medium, can improve the heat dissipation effect.

[0038] It is worth mentioning that a rectangular groove 18 is provided at the bottom of the L-shaped fixing plate 11. A connecting pipe 9 is fixedly installed on one side of the rotating clamp 8. A telescopic heat-conducting pipe 10 connected to the heat-conducting plate 19 is detachably installed on the connecting pipe 9. When welding is required, the telescopic heat-conducting pipe 10 is installed and connected so that the rotating clamp 8 can be connected to the heat-conducting plate 19. This allows the heat generated during the welding process to be quickly conducted away, avoiding heat accumulation in the pipe body. This effectively controls the temperature rise of the oil well pipe, reduces deformation caused by uneven heating, and reduces the risk of deformation or damage to the rotating clamp 8 due to long-term heating, thus protecting the surface quality and dimensional accuracy of the oil well pipe.

[0039] like Figure 4 and Figure 5As shown, the device also includes an auxiliary mechanism, which is installed inside the cooling device to accelerate heat exchange. The auxiliary mechanism includes a rotating shaft 21 rotatably mounted on the top wall of the water tank 12. The bottom end of the rotating shaft 21 is fixedly connected to a turntable 23 located above the heat dissipation plate 20. Multiple sets of impact plates 24 are arranged on the curved surface of the turntable 23. Two rotating rollers 25 are symmetrically installed on the inner top wall of the water tank 12. Several blades 26 are arranged on the curved surface of the rotating rollers 25. The size of the blades 26 matches that of the impact plates 24. A limit frame is fixedly installed on the top of the water tank 12. A motor 22 is fixedly installed on the limit frame. The output shaft of the motor 22 is fixedly connected to the rotating shaft 21. Starting the motor 22 can cause the rotating shaft 21 to drive the turntable 23 to rotate. That is, while the impact plates 24 are rotating, they will also strike the blades 26, causing them to rotate and stir together. This allows the cooling water in the water tank 12 to be in a dynamic flow state at all times, breaking the thermal boundary layer, increasing the heat exchange coefficient between the cooling water, thereby accelerating heat dissipation and improving cooling efficiency.

[0040] In this embodiment, when welding shaping is required, the telescopic heat-conducting pipe 10 is first installed on the connecting pipe 9 so that the heat-conducting plate 19 can be connected and fixed to the rotating clamp 8. At this time, the heat generated during the welding process can be transferred to the heat-conducting plate 19 through the telescopic heat-conducting pipe 10, and then combined with the heat dissipation of the heat sink 20. The dispersed heat is in the cooling water in the water storage tank 12. At this time, the motor 22 is started to make the rotating shaft 21 rotate. The rotation of the rotating shaft 21 causes the turntable 23 to drive the impact plate 24 to rotate and strike the blade 26 to rotate and stir together. This allows the cooling water in the water storage tank 12 to be in a dynamic flow state at all times, breaking the thermal boundary layer and increasing the heat exchange coefficient between the cooling water, thereby accelerating the dissipation of heat, improving the cooling efficiency, and avoiding the local accumulation of heat in the pipe body. This effectively controls the temperature rise of the oil well pipe, reduces deformation caused by uneven heating, and reduces the risk of deformation or damage to the rotating clamp 8 due to long-term heating, protecting the surface quality and dimensional accuracy of the oil well pipe.

[0041] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
