Description

Technical Field

[0001] This utility model relates to the field of tubing straightening technology, and in particular to a continuous tubing straightening device. Background Technology

[0002] A straightening machine is a device used to straighten metal profiles, bars, pipes, wires, etc. The straightening machine uses straightening rollers to compress the bars and other materials to change their straightness. There are generally two rows of straightening rollers. There are various types of straightening machines, including pressure straightening machines, balance roller straightening machines, and shoe roller straightening machines. Straightening machines are often used for straightening steel pipes.

[0003] When straightening oil pipes, if there is rust, oil stains or impurities on the surface of the oil pipe, these impurities may cause poor contact between the straightening roller and the oil pipe, increase frictional resistance, or even cause surface damage (such as indentations and scratches), which will directly affect the straightening effect. Therefore, we propose a continuous oil pipe straightening device. Utility Model Content

[0004] The purpose of this invention is to provide a continuous oil pipe straightening device, which can improve the straightening effect by cleaning the oil pipe before straightening.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a continuous oil pipe straightening device, comprising a straightening box, a support frame integrally formed at the bottom of the straightening box, and a straightening mechanism and a guiding mechanism installed in the straightening box. A sleeve is rotatably connected to the straightening box, and a driving mechanism for driving the sleeve to rotate is installed on the straightening box. An adjustable cleaning mechanism is installed on the sleeve. A crossbeam is installed on the straightening box, and a spraying mechanism is installed on the crossbeam. A pressure rod for squeezing the spraying mechanism is installed on the cleaning mechanism.

[0006] By adopting the above technical solution, when the oil pipe to be straightened is inserted into the straightening box from the right side, the oil pipe will first enter the sleeve through the cleaning mechanism. Then, the drive mechanism will start and drive the cleaning mechanism to rotate outside the sleeve to clean the impurities on the outside of the oil pipe. At the same time, when the cleaning mechanism rotates, it will drive the pressure rod to intermittently squeeze the spraying mechanism, which can spray the cleaning fluid onto the surface of the oil pipe, improve the cleaning effect of the oil pipe, and thus improve the straightening effect of the oil pipe. After cleaning, the oil pipe is inserted into the straightening box and pre-corrected by the guide mechanism. Finally, the straightening mechanism will perform the straightening process.

[0007] A further feature of this invention is that the straightening mechanism employs multiple sets of roller units arranged at equal intervals along the direction of oil pipe travel, with adjacent units arranged in an orthogonal staggered layout to form a three-dimensional straightening system.

[0008] By adopting the above technical solution, the vertically opposed straightening mechanism eliminates the bending deformation of the oil pipe, and the symmetrically arranged straightening mechanism corrects the curvature deviation in the horizontal direction. Through the synergistic effect of multiple sets of rollers, the oil pipe is straightened in an all-round spiral manner, ensuring that the axial straightness and cross-sectional roundness meet the process requirements.

[0009] A further feature of this invention is that the straightening mechanism includes a connecting frame installed on the inner wall of the straightening box and a squeezing roller rotatably connected to the inner side of the connecting frame.

[0010] By adopting the above technical solution, the oil pipe passes through the guide mechanism and is squeezed by the extrusion roller to complete the straightening work of the oil pipe.

[0011] A further feature of this invention is that the guiding mechanism includes a guide roller rotatably connected to the inner wall of the straightening chamber and a rotary motor mounted on the straightening chamber to drive the guide roller to rotate.

[0012] By adopting the above technical solution, the rotating motor starts and drives the guide roller to rotate. When the oil pipe enters from the right side of the straightening box, the oil pipe can be guided and transported.

[0013] A further feature of this invention is that the driving mechanism includes a drive motor mounted on the straightening housing, a first gear mounted on the output shaft of the drive motor, and a second gear meshing with the first gear mounted on the outside of the sleeve.

[0014] By adopting the above technical solution, the drive motor starts and drives gear one to rotate. When gear one rotates, it rotates together with gear two, thereby driving the cleaning structure on the sleeve to rotate, cleaning impurities on the outside of the oil pipe, and thus improving the straightening effect of the oil pipe.

[0015] A further feature of this invention is that the cleaning mechanism includes side plates symmetrically arranged on the sleeve, a brush plate slidably connected to the side plates, and bolts threadedly connecting the side plates and the brush plate. The side plates are provided with multiple threaded holes for bolt fixing.

[0016] By adopting the above technical solution, the brush plate slides on the side plate and is then connected to the threaded holes at different positions using bolts. After the brush plate wears out from long-term operation, the distance between the two brush plates can be changed to ensure that the brush plate can contact the outside of the oil pipe and clean the oil pipe.

[0017] A further feature of this invention is that the spraying mechanism includes a liquid storage box and a compressed air bladder mounted on the crossbeam. An inlet pipe is connected between the compressed air bladder and the liquid storage box, and a spray pipe is connected to the other side of the compressed air bladder. Both the inlet pipe and the spray pipe are equipped with one-way valves. A pressure rod is mounted on a brush plate and compresses the compressed air bladder along with the brush plate.

[0018] By adopting the above technical solution, the sleeve drives the brush plate to rotate through rotation, which in turn drives the pressure rod to move synchronously. The end of the pressure rod is designed with an arc-shaped contact surface, which periodically squeezes the air bladder during the rotation cycle, forming a reciprocating pumping action. When the air bladder resets and draws air, the cleaning fluid in the reservoir is drawn into the air bladder through the inlet pipe. Its one-way valve is designed to prevent backflow. When the air bladder is pressurized and vents air, the internal pressure increases, pushing the cleaning fluid through the spray pipe to spray out and cover the surface of the oil pipe. During the air intake stage, new cleaning fluid is replenished through negative pressure to form a continuous cycle, improving the cleaning effect of the oil pipe and thus improving the straightening effect of the oil pipe.

[0019] The beneficial effects of this utility model are as follows: When the oil pipe to be straightened is inserted into the straightening box from the right side, the oil pipe will first enter the sleeve through the cleaning mechanism. Then, the drive mechanism will start and drive the cleaning mechanism to rotate outside the sleeve to clean the impurities on the outside of the oil pipe. At the same time, when the cleaning mechanism rotates, it drives the pressure rod to intermittently squeeze the spraying mechanism, which can spray the cleaning fluid on the surface of the oil pipe, improve the cleaning effect of the oil pipe, and thus improve the straightening effect of the oil pipe.

[0025] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1-3 This utility model provides a continuous oil pipe straightening device, including a straightening box 1, a support frame 2 integrally formed at the bottom of the straightening box 1, and a straightening mechanism 3 and a guiding mechanism 4 installed inside the straightening box 1. A sleeve 5 is rotatably connected to the straightening box 1, and a driving mechanism 6 for driving the sleeve 5 to rotate is installed on the straightening box 1. An adjustable cleaning mechanism 7 is installed on the sleeve 5. A crossbeam 8 is installed on the straightening box 1, and a spraying mechanism 9 is installed on the crossbeam 8. A pressure rod 10 that can compress the spraying mechanism 9 is installed on the cleaning mechanism 7. When the oil pipe to be straightened is inserted into the straightening box 1 from the right side, the oil pipe will first enter the sleeve 5 through the cleaning mechanism 7. Then, the drive mechanism 6 starts and drives the cleaning mechanism 7 to rotate outside the sleeve 5 to clean the impurities on the outside of the oil pipe. At the same time, when the cleaning mechanism 7 rotates, it drives the pressure rod 10 to intermittently squeeze the spraying mechanism 9, which can spray the cleaning fluid onto the surface of the oil pipe, improve the cleaning effect of the oil pipe, and thus improve the straightening effect of the oil pipe. After cleaning, the oil pipe is inserted into the straightening box 1 and pre-corrected by the guide mechanism 4. Finally, it is straightened by the straightening mechanism 3.

[0027] The straightening mechanism 3 adopts multiple sets of roller units arranged at equal intervals along the direction of oil pipe travel. Adjacent units are arranged in an orthogonal staggered layout to form a three-dimensional straightening system. The vertically opposed straightening mechanism 3 eliminates the vertical bending deformation of the oil pipe, and the symmetrically arranged straightening mechanism 3 corrects the curvature deviation in the horizontal direction. Through the synergistic effect of multiple sets of roller units, the oil pipe is straightened in an all-round spiral manner, ensuring that the axial straightness and cross-sectional roundness meet the process requirements.

[0028] The straightening mechanism 3 includes a connecting frame 31 installed on the inner wall of the straightening box 1 and a squeezing roller 32 rotatably connected to the inner side of the connecting frame 31. After the oil pipe passes through the guide mechanism 4, it is squeezed by the squeezing roller 32 to complete the straightening work of the oil pipe.

[0029] The guiding mechanism 4 includes a guide roller 41 rotatably connected to the inner wall of the straightening box 1 and a rotating motor 42 installed on the straightening box 1 to drive the guide roller 41 to rotate. When the rotating motor 42 is started, it drives the guide roller 41 to rotate. When the oil pipe enters from the right side of the straightening box 1, it can guide and transport the oil pipe.

[0030] The drive mechanism 6 includes a drive motor 61 mounted on the straightening housing 1. A gear 62 is mounted on the output shaft of the drive motor 61. A gear 63 that meshes with the gear 62 is mounted on the outside of the sleeve 5. When the drive motor 61 starts, it drives the gear 62 to rotate. When the gear 62 rotates, it rotates with the gear 63, thereby driving the cleaning structure 7 on the sleeve 5 to rotate, cleaning impurities on the outside of the oil pipe, and thus improving the straightening effect of the oil pipe.

[0031] The cleaning mechanism 7 includes side plates 71 symmetrically arranged on the sleeve 5, brush plates 72 slidably connected to the side plates 71, and bolts 73 threadedly connecting the side plates 71 and the brush plates 72. The side plates 71 are provided with multiple threaded holes for fixing the bolts 73. The brush plates 72 slide on the side plates 71 and are then connected to the threaded holes at different positions by the bolts 73. After the brush plates 72 wear out from long-term operation, the distance between the two brush plates 72 can be changed to ensure that the brush plates 72 can contact the outside of the oil pipe and clean the oil pipe.

[0032] The spraying mechanism 9 includes a liquid storage box 91 and a compression air bladder 92 mounted on the cross frame 8. An inlet pipe 93 connects the compression air bladder 92 to the liquid storage box 91. A spray pipe 94 connects to the other side of the compression air bladder 92. Both the inlet pipe 93 and the spray pipe 94 are equipped with one-way valves. A pressure rod 10 is mounted on a brush plate 72 and compresses the compression air bladder 92 along with the brush plate 72. The sleeve 5 drives the brush plate 72 to rotate through rotation, simultaneously driving the pressure rod 10 to move synchronously. The end of the pressure rod 10 is designed with an arc-shaped joint. During the rotation cycle, the contact surface periodically squeezes the compression bladder 92, forming a reciprocating pumping action. When the compression bladder 92 returns to its original position and draws in air, the cleaning fluid in the reservoir 91 is drawn into the compression bladder 92 through the inlet pipe 93. Its one-way valve is designed to prevent backflow. When the compression bladder 92 is pressurized and vents air, the internal pressure increases, pushing the cleaning fluid through the spray pipe 94 to spray out and cover the surface of the oil pipe. During the air intake phase, new cleaning fluid is replenished through negative pressure to form a continuous cycle, improving the cleaning effect of the oil pipe and thus improving the straightening effect of the oil pipe.

[0033] Furthermore, the compression airbag 92 is made of corrosion-resistant elastic material (such as silicone) and can adapt to frequent compression deformation.

[0034] Furthermore, the connecting frame 31 can be fixed to the inner wall of the straightening box 1 by a cylinder, which makes it easy to change the distance between the two extrusion rollers 32 in the same group, and can straighten oil pipes of different diameters. The adjustable cleaning structure 7 also makes it easy to clean oil pipes of different diameters.

[0035] Furthermore, the pressure rod 10 is composed of two telescopic sleeves connected together. The two sleeves are slidably connected to each other and fixed by screws. When adjusting the distance between the two brush plates 72, the pressure rod 10 can adjust the distance accordingly to ensure that the pressure rod 10 can squeeze and compress the airbag 92.
