[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A straightening device for low-stress steel pipes includes a base plate 1. V-shaped support conveying components 2 are provided on both sides of the top of the base plate 1. A steel round pipe 3 is placed between the tops of the two V-shaped support conveying components 2. An elastic buffer straightening component 4 is sleeved on the surface of the steel round pipe 3.

[0029] The elastic buffer straightening assembly 4 includes a mounting sleeve 41, which is fitted onto the surface of the steel round tube 3. Mounting brackets 42 are slidably arranged on the front, rear and top sides inside the mounting sleeve 41. A straightening long roller 43 is rotatably arranged inside the mounting bracket 42. A buffer pad 44 is fitted onto the surface of the straightening long roller 43. The straightening long roller 43 is located inside the mounting sleeve 41 and is used in conjunction with the steel round tube 3.

[0030] In this embodiment: the base plate 1 serves as the basic support component of the entire device. The V-shaped support conveying components 2 arranged on both sides of the top of the base plate 1 provide stable support and conveying function for the steel tube 3. The steel tube 3 is placed between the tops of the two V-shaped support conveying components 2 to ensure its stable position on the device. At the same time, the surface of the steel tube 3 is fitted with an elastic buffer straightening component 4. The mounting sleeve 41 of the elastic buffer straightening component 4 is fitted on the surface of the steel tube 3. The straightening long roller 43 is rotatably arranged in the mounting frame 42 that is slidably arranged on the front, rear and top sides of the mounting sleeve 41. The buffer pad 44 fitted on the surface of the straightening long roller 43 contacts and cooperates with the steel tube 3. In this way, when straightening the steel tube 3, local stress concentration can be avoided, the low stress state of the steel tube can be protected, and the straightening quality can be improved.

[0031] Specifically, such as Figure 2 As shown, the V-shaped support conveying assembly 2 includes a first mounting base 21, the bottom of which is bolted to the top of the substrate 1.

[0032] Specifically, such as Figure 2 As shown, a second mounting base 22 is bolted to the front and rear sides of the top two sides of the first mounting base 21. A conveying roller 23 is rotatably arranged inside the second mounting base 22, and two adjacent conveying rollers 23 are arranged at a V-shaped angle.

[0033] Specifically, such as Figure 2 As shown, the surface of the conveyor roller 23 is covered with an anti-slip and wear-resistant pad 24, which is in contact with the surface of the steel round tube 3.

[0034] In this embodiment: the bottom of the first mounting base 21 in the V-shaped support conveying assembly 2 is bolted to the top of the substrate 1, ensuring the stable installation of the entire V-shaped support conveying assembly 2 on the substrate 1. The front and rear sides of the top of the first mounting base 21 are bolted to the second mounting base 22, and the conveying roller 23 is rotatably arranged inside the second mounting base 22. The two adjacent conveying rollers 23 are arranged at a V-shaped angle. The conveying motor 9 is bolted to one side of the second mounting base 22, and its output shaft extends into the second mounting base 22 and is bolted to the conveying roller 23. When the conveying motor 9 is started, it drives the conveying roller 23 to rotate, thereby realizing the transmission of the steel round tube 3 placed on the conveying roller 23. The anti-slip and wear-resistant pad 24 sleeved on the surface of the conveying roller 23 contacts the surface of the steel round tube 3, increasing the friction and ensuring that the steel round tube 3 will not slip during the transmission process, thus ensuring the stability of the transmission.

[0035] Specifically, such as Figure 5 As shown, the bottom sides of the mounting sleeve 41 are respectively bolted with the first telescopic electric cylinder 5, and the bottom of the first telescopic electric cylinder 5 is bolted to the top of the base plate 1.

[0036] Specifically, such as Figure 4 , Figure 5 As shown, the top, front and rear sides of the mounting sleeve 41 are all bolted with a fixing frame 6. The fixing frame 6 is equipped with a second telescopic electric cylinder 7. The side of the second telescopic electric cylinder 7 closest to the mounting frame 42 is bolted to the mounting frame 42.

[0037] Specifically, such as Figure 4 As shown, straightening motors 8 are bolted to both sides of the mounting frame 42. The output shaft of the straightening motor 8 extends into the mounting frame 42 and is bolted to the straightening roller 43.

[0038] In this embodiment: The first telescopic electric cylinder 5 is bolted to both sides of the bottom of the mounting sleeve 41 of the elastic buffer straightening assembly 4. Its bottom is bolted to the top of the base plate 1. Through the telescopic movement of the first telescopic electric cylinder 5, the height of the mounting sleeve 41 can be adjusted so that the mounting sleeve 41 can adapt to steel round tubes 3 of different diameters, thereby aligning the straightening center with the center line of the steel round tube 3, creating conditions for flexible straightening. The top, front and rear sides of the mounting sleeve 41 are all bolted to the fixing frame 6. The second telescopic electric cylinder 7 is set inside the fixing frame 42 and is bolted to the mounting frame 42 on the side near the mounting frame 42. The telescopic movement of the second telescopic electric cylinder 7 can push the mounting frame 42 to slide inside the mounting sleeve 41, thereby adjusting the contact pressure between the straightening long roller 43 and the steel round tube 3. The straightening motor 8 is bolted to both sides of the mounting frame 42. Its output shaft extends into the mounting frame 42 and is bolted to the straightening long roller 43. After the straightening motor 8 is started, it drives the straightening long roller 43 to rotate, which, together with the buffer pad 44 on the surface, straightens the steel round tube 3 and avoids local stress concentration.

[0039] Specifically, such as Figure 2 , Figure 3As shown, a conveyor motor 9 is bolted to one side of the second mounting base 22, and the output shaft of the conveyor motor 9 extends into the interior of the second mounting base 22 and is bolted to the conveyor roller 23.

[0040] Specifically, such as Figure 3 As shown, a third telescopic electric cylinder 10 is provided inside the first mounting base 21, and a third mounting base 11 is bolted to the top of the third telescopic electric cylinder 10. Two pipe rotation support rollers 12 are rotatably arranged inside the third mounting base 11.

[0041] In this embodiment: The transmission motor 9, bolted to one side of the second mounting base 22, has its output shaft extending into the second mounting base 22 and bolted to the transmission roller 23. The transmission motor 9 drives the transmission roller 23 to rotate, thereby conveying the steel round tube 3. The third telescopic electric cylinder 10 is installed inside the first mounting base 21. Two pipe rotation support rollers 12 are rotatably installed inside the third mounting base 11 bolted to its top. When it is necessary to lift the steel round tube 3 and support its rotation for straightening, the third telescopic electric cylinder 10 extends upward, so that the pipe rotation support rollers 12 contact the steel round tube 3 and lift it. At the same time, when the straightening long roller 43 rotates and straightens the steel round tube 3, it can provide a support platform for the rotation of the steel round tube 3. The steel round tube 3 can rotate on the support rollers, ensuring the normal operation of the straightening long roller 43.

[0042] Specifically, such as Figure 5 As shown, a stand block 13 is bolted to the left side of the front side of the substrate 1, and a laser measuring instrument 14 and a controller 15 are bolted to the top of the stand block 13.

[0043] In this embodiment, the vertical block 13 bolted to the left side of the front side of the base plate 1, and the laser measuring instrument 14 and controller 15 bolted to its top, play an important role in the entire straightening process. The laser measuring instrument 14 can monitor the steel tube 3 before and after straightening in real time, obtain data such as the bending degree of the steel tube, and transmit this data to the controller 15. The controller 15 analyzes and judges whether the steel tube 3 has reached the straightening standard based on the received data. If it has not reached the standard, the controller 15 can control the actions of the first telescopic electric cylinder 5, the second telescopic electric cylinder 7, the straightening motor 8, the conveying motor 9, and the third telescopic electric cylinder 10, and adjust the pressure of the straightening roller 43 on the surface of the steel tube 3, as well as the position and rotation state of the steel tube 3, so that the device repeatedly performs the straightening action until the steel tube 3 reaches the straightening standard, thereby ensuring the straightening accuracy.

[0044] Working principle: Based on the base plate 1 as the basic support component, the V-shaped support conveying assemblies 2 on both sides of its top provide stable support and conveying function for the steel round tube 3. The steel round tube 3 is placed between the tops of the two V-shaped support conveying assemblies 2, and an elastic buffer straightening assembly 4 is fitted on its surface. In the V-shaped support conveying assembly 2, the bottom of the first mounting base 21 is bolted to the base plate 1 to ensure the stability of the assembly. The conveying rollers 23 are rotatably installed in the second mounting bases 22 on the front and rear sides of its top. The front and rear adjacent conveying rollers 23 form a V-shaped angle. The conveying motor 9 on one side of the second mounting base 22 drives the conveying rollers 23 to rotate. The anti-slip and wear-resistant pads 24 on the surface of the conveying rollers 23 increase the friction and ensure stable transmission of the round tube. The bottom sides of the mounting sleeve 41 of the elastic buffer straightening assembly 4 are connected to the base plate 1 through the first telescopic electric cylinder 5, and the height of the mounting sleeve 41 can be adjusted. The straightening center is aligned with the center line of the round tube. The second telescopic electric cylinder 7 in the top, front and rear fixing frame 6 of the mounting sleeve 41 pushes the mounting frame 42 to slide, adjusting the contact pressure between the straightening long roller 43 and the round tube. The straightening motor 8 drives the straightening long roller 43 to rotate, and the buffer pad 44 helps to avoid local stress concentration. The third telescopic electric cylinder 10 in the first mounting seat 21 and the pipe rotation support roller 12 in the top of the third mounting seat 11 can lift the round tube and provide support for its rotation and straightening when needed. The laser measuring instrument 14 on the top of the left side of the front block 13 of the base plate 1 monitors the bending degree of the round tube and transmits it to the controller 15 in real time. If the straightening standard is not met, the controller 15 controls the action of each electric cylinder and motor to adjust the straightening pressure, the position of the round tube and the rotation state until the round tube reaches the straightening standard, ensuring the straightening accuracy.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
