DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 6 The utility model provides a technical solution: a steel pipe straightening device, including a base plate 23, on which are installed: a bracket 1, a cylinder 2, a limiting frame 3, a driving mechanism, a straightening mechanism and a cleaning mechanism, a plurality of brackets 1 are respectively fixedly installed on the top of the base plate 23; the outer side of the outer wall of the cylinder 2 is fixedly connected to the ends of the plurality of brackets 1; two limiting frames 3 are respectively installed at both ends of the cylinder 2; the driving mechanism is arranged at the top of the base plate 23 and is rotatably connected to the two limiting frames 3; the straightening mechanism is spirally fixed inside the cylinder 2; the cleaning mechanism is arranged at the top of the base plate 23 and is located on one side of the driving mechanism.

[0021] During the specific implementation process, it should be noted that when it is necessary to straighten the steel pipe, the operator places the steel pipe at the cylinder 2 on the bracket 1, and then starts the driving mechanism. In the process of the driving mechanism pushing the steel pipe forward, the cleaning mechanism begins to clean the outer surface of the steel pipe, removes the debris on the surface of the steel pipe, and ensures that the surface of the steel pipe is clean. This is convenient for the subsequent straightening of the steel pipe. The driving mechanism starts to push the steel pipe into the straightening mechanism. The straightening mechanism is located inside the cylinder 2 and is spirally fixed to ensure that the steel pipe remains stable during the straightening process. The straightening mechanism enables the steel pipe to achieve the required straightness. The cleaning mechanism keeps the outer surface of the steel pipe clean to ensure that it is not disturbed by debris during the straightening process. At the same time, the driving mechanism and the straightening mechanism work together to complete the straightening task of the steel pipe.

[0022] In some examples, further, the driving mechanism includes: a shell 4, a rotating member 5, a driving motor 6, a propulsion wheel 7 and a first gear 8, two shells 4 are fixedly arranged at the top of the base; the bottom ends of several rotating members 5 respectively penetrate the upper wall of the shell 4 and are rotatably connected to the bottom end inside the shell 4, and the other ends are rotatably connected to two limit frames 3; the driving motor 6 is fixedly arranged inside one of the shells 4, and the driving end is fixedly connected to one of the rotating members 5; several propulsion wheels 7 are respectively fixedly installed on the outside of the outer walls of several rotating members 5, and the outer edges are arc-shaped and are concentrically arranged on the cylinder 2; the two first gears 8 are respectively fixedly mounted on the outside of the outer walls of the two rotating members 5, and are located inside the shell 4.

[0023] During the specific implementation process, it should be noted that when straightening the steel pipe, the operator will start the drive motor 6, and the drive motor 6 is fixedly connected to one of the rotating parts 5 through its drive end. When the drive motor 6 starts to rotate, it drives the rotating part 5 to start rotating. The rotation of the rotating part 5 further drives the propulsion wheel 7 installed on the outside of its outer wall to rotate. The propulsion wheel 7 is concentrically arranged with the cylinder 2, so it can smoothly push the steel pipe. At the same time, the first gear 8 is also installed on the outside of the outer wall of the rotating part 5 and is located inside the shell 4. It works in coordination with the rotation of the propulsion wheel 7. Through the mutual cooperation of the first gear 8, the propulsion wheel produces relative motion, thereby pushing the steel pipe smoothly into the straightening mechanism. The drive motor 6 provides continuous power, and the coordinated operation of the rotating part 5 and the propulsion wheel 7 ensures the stable advancement of the steel pipe during the straightening process, and finally achieves efficient and accurate steel pipe straightening tasks.

[0024] In some examples, further, the straightening mechanism includes: a fixing part 9, a hinge seat 10 and a straightening wheel 11, and several fixing parts 9 are respectively arranged on the cylinder 2 in a spiral manner; several hinge seats 10 are respectively fixedly installed on the ends of several fixing parts 9, and are located on the inner side of the cylinder 2; several straightening wheels 11 are respectively arranged on the hinge seats 10 and can be rotated along their own axes, and the outer edge parts are arranged in an arc shape and are concentric with the cylinder 2.

[0025] During the specific implementation process, it should be noted that the fixing member 9 is arranged on the inner side of the cylinder 2 in a spiral manner, and the fixing member 9 ensures the structural stability of the straightening mechanism. A hinge seat 10 is installed at the end of each fixing member 9, and the straightening wheel 11 is arranged on these hinge seats 10, which can rotate freely along its own axis. The outer edge of the straightening wheel 11 is designed to be arc-shaped and is arranged concentrically with the cylinder 2, so that the straightening wheel 11 can better fit the surface of the steel pipe when rotating, thereby improving the straightening accuracy. During the straightening process, the steel pipe is pushed through these concentrically arranged straightening wheels 11. During the continuous advancement of the steel pipe, the straightening wheel 11 applies uniform pressure to the steel pipe through its rotation, gradually corrects the bending or twisting of the steel pipe, and makes it reach the required straightness. The fixing member 9 maintains the correct position of the straightening wheel 11, and the hinge seat 10 ensures the stable rotation of the straightening wheel 11. The combined effect enables the steel pipe to be effectively corrected when passing through the straightening mechanism.

[0026] In some examples, further, the cleaning mechanism includes: a cover body 12, a rotating assembly, a turntable 13, a wire drawing rod 14, a movable plate 15 and a cleaning assembly, the cover body 12 is arranged at the top of the substrate 23, and a notch is opened at the top of the cover body 12; the rotating assembly is installed inside the cover body 12; the turntable 13 is rotatably arranged on the inner side of the cover body 12, and is meshed with the rotating assembly, a through hole is arranged in the middle part of the turntable 13, and a plurality of teeth are opened on the outer side of the outer wall of the turntable 13; the wire drawing rod 14 is rotatably arranged at the through hole in the middle part of the turntable 13, and a nut is arranged at the end; the two movable plates 15 are respectively screwed on the outer side of the outer wall of the wire drawing rod 14; the cleaning assembly is relatively installed on the two movable plates 15.

[0027] In the specific implementation process, it should be noted that the cover body 12 is arranged at the top of the substrate 23, and a notch is designed at the top thereof. The notch is used to provide a rotating track for the wire drawing rod 14 during the rotation of the turntable 13, so that the steel pipe can pass smoothly and be straightened by the straightening mechanism inside the cover body 12. The rotating assembly is installed inside the cover body 12 and meshes with the inner turntable 13. The turntable 13 can rotate freely inside the cover body 12, and a through hole is provided in the middle part thereof, and a plurality of latch teeth are provided on the outer side of the outer wall, which help the turntable 13 to mesh firmly with the rotating assembly. The wire drawing rod 14 is installed at the through hole in the turntable 13, and the wire drawing rod 14 is rotatable and has a nut at the end, so that it can adjust the distance between the two moving plates 15 according to the diameter of the steel pipe. The moving plate 15 can move along the wire drawing rod by rotating the wire drawing rod 14, thereby adjusting its position. The cleaning assembly is relatively installed on the two moving plates 15, and the position can be adjusted accordingly according to the size of the steel pipe and the cleaning requirements. In the cleaning stage before straightening the steel pipe, the steel pipe enters the cover 12 and fits with the straightening wheel 11, and the wire drawing rod 14 is rotated to change the distance between the two moving plates 15 to adapt to the size of the steel pipe. By adjusting the wire drawing rod 14, the moving plate 15 drives the cleaning component to gradually approach the surface of the steel pipe, and then cleans the outer surface of the steel pipe. The design of the cleaning component enables it to scrape off the debris and dirt on the surface of the steel pipe, ensuring that the surface of the steel pipe is clean before entering the straightening mechanism. The surface quality of the steel pipe during the straightening process is ensured, thereby improving the straightening effect and accuracy.

[0028] In some examples, further, the rotating assembly includes: a first rotating motor 16, a rotating shaft 17 and a second gear 18, the first rotating motor 16 is fixedly mounted inside the cover body 12; the rotating shaft 17 is fixedly mounted on the driving end of the first rotating motor 16; the two second gears 18 are respectively fixedly mounted on the outside of the outer wall of the rotating shaft 17, and are meshed with a plurality of teeth.

[0029] In the specific implementation process, it should be noted that the first rotary motor 16 is fixedly installed inside the cover 12, and is responsible for providing rotary power as a driving source. The rotating shaft 17 is fixedly installed on the driving end of the first rotary motor 16, so that the rotating shaft 17 can rotate with the rotation of the motor. Two second gears 18 are installed on the outer side of the outer wall of the rotating shaft 17, and the second gears 18 are meshed with a plurality of teeth on the rotating disk 13 to form a gear transmission system.

[0030] When the first rotating motor 16 is started, the rotating power is transmitted to the second gear 18 through the rotating shaft 17. The mutual engagement between the second gear 18 and the latching teeth ensures that the rotating disk 13 can rotate stably. As the rotating disk 13 rotates, the cleaning assembly installed on the moving plate 15 also rotates to clean the outer surface of the steel pipe. This allows the cleaning assembly to contact the surface of the steel pipe in all directions and effectively scrape off hard debris and dirt.

[0031] In the whole working process, the first rotating motor 16, as the power core, realizes the stable rotation of the turntable 13 through the transmission of the rotating shaft 17 and the second gear 18, thereby driving the cleaning component to clean the steel pipe efficiently. The setting of the rotating component not only improves the cleaning efficiency, but also ensures the continuity and uniformity of the cleaning process, providing good surface conditions for the subsequent straightening steps.

[0032] In some examples, further, the cleaning assembly includes: a second rotating motor 19, a roller brush 20, a sprocket 21 and a chain 22, the second rotating motor 19 is fixedly mounted on the two movable plates 15; the two roller brushes 20 are rotatably mounted on the two movable plates 15 respectively; a plurality of sprockets 21 are fixedly mounted on the driving end of the second rotating motor 19 and the ends of the two roller brushes 20 in a group of two; the chains 22 are respectively mounted on the sprockets 21.

[0033] In the specific implementation process, it should be noted that the second rotary motor 19 is fixedly mounted on two moving plates 15, and the moving plates 15 can be adjusted along the wire drawing rod 14 to adapt to steel pipes of different diameters. Each roller brush 20 is rotatably mounted on the corresponding moving plate 15, so that the roller brush 20 can effectively contact and clean the surface of the steel pipe. When the cleaning process begins, the second rotary motor 19 is started to drive the sprocket 21 connected to its driving end to rotate. The end of each roller brush 20 is also equipped with a sprocket 21, and the sprocket 21 is connected to the sprocket 21 of the second rotary motor 19 through a chain 22. The function of the chain 22 is to transfer the rotational power from the motor to the roller brush 20, so that the roller brush 20 rotates under the drive of the motor. As the roller brush 20 rotates, the outer surface of the steel pipe begins to be deeply cleaned, effectively removing debris, rust and other attachments. In this process, the second rotary motor 19 provides continuous rotational power, and the efficient operation of the roller brush 20 is ensured through the coordinated work of the sprocket 21 and the chain 22. The rotation speed and contact pressure of the roller brush 20 are precisely controlled to meet the cleaning requirements under different conditions.

[0034] During the entire work process, the linkage mechanism of the second rotating motor 19 and the roller brush 20 not only provides a powerful cleaning function, but also allows customized cleaning of steel pipes of different sizes through the adjustable movable plate 15, thereby ensuring that the steel pipes achieve ideal surface cleanliness before entering the straightening mechanism, providing the necessary prerequisite for a high-quality straightening process.
