Description

Technical Field

[0001] This invention relates to the field of steel welding straightening technology, and in particular to an automatic welding anti-deformation device for steel structures. Background Technology

[0002] The H-beam straightening machine is a device specifically designed to correct deformation of H-beam flanges after welding. Its core function is to eliminate bending or angular deformation of the flanges caused by welding heat input through mechanical force. The device utilizes a perforated lever system composed of an upper pressure roller and a transmission roller to cause the H-beam flanges to undergo controllable reverse bending deformation as they pass through the rollers. After elastic recovery, precise straightening is achieved. The machine mainly includes a base, frame, straightening rollers, pressure rollers, guide rollers, and a PLC automatic control system. It supports hydraulic or electric pressing devices to accommodate different flange thicknesses.

[0003] However, in practical applications, some problems remain unresolved. Here are some common issues with H-beam straightening machines: During the straightening process, weld slag and adhesive residue adhere to the steel surface. If these cannot be cleaned promptly, it affects the straightening accuracy and quality. Weld slag forms localized protrusions, preventing the pressure rollers from evenly contacting the flange surface. The straightening force cannot be effectively transmitted to the deformed area, resulting in under-straightening or over-straightening. Hard weld slag, under the pressure of the high-pressure rollers, is pressed into the steel surface, forming pits or scratches, damaging the surface integrity. Simultaneously, the weld slag contains hard particles such as metal oxides, accelerating roller surface wear, leading to decreased roller surface accuracy and even grooves, requiring frequent roller replacement. Adhesive residue reduces the friction coefficient between the steel and the rollers, potentially causing slippage and deviation of the steel profile. Residual adhesive residue on the roller surface attracts metal debris, forming an abrasive layer that exacerbates wear. Summary of the Invention

Detailed Implementation

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example

[0038] Reference Figures 1-9 This is the first embodiment of the present invention. This embodiment provides an automatic welding anti-deformation device for steel structures. The automatic welding anti-deformation device for steel structures includes a straightening machine body 1, a cleaning mechanism 2, and a support mechanism 3.

[0039] Specifically, the main body 1 of the straightening machine is an H-beam straightening machine, which can straighten the H-beams after welding and play a role in reversing deformation. This is existing technology, and the working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0040] Specifically, the cleaning mechanism 2 is fixed to the surface of the main body 1 of the straightening machine, including a fixed frame 211 fixed to one side of the main body 1 of the straightening machine, a support frame 21 fixed to the upper end of the fixed frame 211, and a frame 22 fixed to the top of the support frame 21. There are two frames 22, which are symmetrically distributed on the top of the support frame 21. A driving component 23 and a transmission component 24 are respectively installed on the frame 22, and the driving component 23 and the transmission component 24 cooperate with each other.

[0041] By setting the drive component 23, when the welded H-beam is transported onto it, force is applied to it, and the transmission component 24 is activated through the linkage of the structure, causing the L-shaped plates 25 on both sides to move. This causes the scraper blocks 26, 27, and 3 28 on them to move closer to the vertically placed H-beam and contact the corner area below the vertically placed H-beam. During the process of straightening and transporting the welded H-beam, the area on the straightening path of the welded H-beam is cleaned.

[0042] Weld slag and adhesive residue remaining on the H-beam are scraped off to reduce their entry into the straightening machine body 1 along with the H-beam, thereby improving the quality of straightening and reducing the amount of residue adhering to the rollers on the straightening machine body 1 after straightening, thus avoiding any impact on the straightening of subsequent welded H-beams. Multiple scraper blocks 1 26 and two scraper blocks 27 are provided on an L-shaped plate 25, and the scraper blocks 1 26, scraper blocks 27 and L-shaped plate 25 are all sealed to each other.

[0043] An L-shaped plate 25 is fixed on the transmission component 24. Scraper block 1 26 and scraper block 27 slide inside the L-shaped plate 25 respectively. Scraper block 3 28 slides on the two scraper blocks 1 26. The setting of scraper block 3 28 allows it to make better contact with the corner of the conveyed H-beam, ensuring the cleaning effect. At the same time, it can move on the two scraper blocks 1 26 at the right angle of the L-shaped plate 25. When the two scraper blocks 1 26 move in different directions on the L-shaped plate 25, scraper block 3 28 will not obstruct it or affect its movement. Feedback component 29 is installed on the L-shaped plate 25 and the support frame 21 and is set on scraper blocks 1 26 and scraper block 27 to cooperate with it. A lower scraper 210 is fixed on one side of the frame 22.

[0044] With the feedback component 29 in place, multiple scraper blocks 26 and two scraper blocks 27 on the L-shaped plate 25 move with it. After contacting the surface at the right angle of the H-beam, the component can act on scraper blocks 26 and 27 to ensure close adaptive contact with the surface at the right angle of the H-beam, improving the cleaning effect and flexibility. When the surface of the H-beam has a special structure, ordinary scraper plates cannot meet the requirements. Scraper blocks 26 and 27 on the two L-shaped plates 25 can be brought close together for adaptive contact. Then, scraper blocks 26 and 27 corresponding to the special area structure can be fixed, and then normal cleaning and correction operations can be performed. When it is necessary to fix all scraper blocks 26 and 27 and not to make adaptive contact, corresponding operations can also be performed for limiting and fixing to meet different usage requirements.

[0045] The lower scraper 210 can clean the bottom of the vertically placed H-beam after welding, improving the quality of straightening and reducing the amount of residue adhering to the drive wheel of the straightening machine body 1, thus reducing slippage during conveying and its impact on subsequent H-beam straightening.

[0046] Specifically, the support mechanism 3 is set on both sides of the straightening machine body 1. The support mechanism 3 can provide rolling support for the welded H-beams. While providing support, it does not affect the movement of the straightening machine body 1 in straightening and conveying the H-beams. This is existing technology. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here. Example

[0047] Reference Figures 2-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0048] Specifically, the driving component 23 includes a slider 23-1 that slides on the frame 22. A roller 23-2 rotates on the slider 23-1. The roller 23-2 is rotatably connected to the slider 23-1 through a bearing. As the H-beam on the support mechanism 3 moves continuously into the straightening machine body 1, the H-beam contacts and is squeezed by the roller 23-2, causing it to move downward. This causes the slider 23-1 and the vertical rod 23-4 to move downward. After the roller 23-2 makes elastic contact with the bottom of the H-beam, it does not affect the normal movement of the H-beam. The roller 23-2 rotates when the H-beam moves.

[0049] A support block 23-3 is fixed to the inner wall of the frame 22. A vertical rod 23-4 slides on the frame 22 and the support frame 21, with its upper end passing through the support block 23-3 and fixed to the bottom of the slider 23-1. A spring 23-5 is sleeved on the upper surface of the vertical rod 23-4, and its two ends are fixed to the bottom of the slider 23-1 and the top of the support block 23-3, respectively. Through the setting of the spring 23-5, it is compressed when the slider 23-1 moves down. The elastic force generated makes the roller 23-2 elastically contact the bottom of the H-beam. After the H-beam separates from the surface of the roller 23-2, it provides a force for the reset of the slider 23-1, the vertical rod 23-4 and the roller 23-2.

[0050] A sleeve 23-6 rotates on the support block 23-3 and is fitted onto the surface of the vertical rod 23-4. The sleeve 23-6 is rotatably connected to the support block 23-3 through a bearing. The sleeve 23-6 is movably fitted onto the surface of the vertical rod 23-4. A drive frame 23-7 is fixed on the lower end surface of the sleeve 23-6 and cooperates with the transmission component 24. A guide groove 23-8 is opened on the inner wall of the sleeve 23-6. A guide post 23-9 is fixed on the surface of the vertical rod 23-4 and slides in the guide groove 23-8.

[0051] The guide groove 23-8 is divided into three parts. The first and third parts are where the guide post 23-9 will not cause the sleeve 23-6 to rotate when it moves inside. The second part is where the guide post 23-9 can cause the sleeve 23-6 to rotate when it moves inside. Through the setting of the guide groove 23-8 and the guide post 23-9, when the H-beam contacts and is squeezed by the roller 23-2 to move downward, the slider 23-1 and the vertical rod 23-4 can move downward, thereby causing the guide post 23-9 to move from the first part of the guide groove 23-8 on the sleeve 23-6 to the second part, causing the sleeve 23-6 to rotate, thereby causing the drive frame 23-7 to rotate and drive the transmission component 24, causing the transmission component 24 to drive the L-shaped plate 25 on it to move closer to the H-beam.

[0052] The transmission component 24 includes a T-shaped plate 24-1 fixed to one side of the frame 22, a sliding sleeve 24-2 sliding on the T-shaped plate 24-1, two T-shaped plates 24-1 respectively on one frame 22, and two sliding sleeves 24-2 fitted on an L-shaped rod 24-4. The two sets of T-shaped plates 24-1 and sliding sleeves 24-2 better limit the L-shaped rod 24-4, so that the L-shaped rod 24-4 always remains vertical and does not tilt when moving laterally. A guide frame 24-3 is fixed to one side of the frame 22, and the L-shaped rod 24-4 slides on the sliding sleeve 24-2. A guide rod 24-5 is fixed to the surface of the L-shaped rod 24-4 and slides within the guide frame 24-3. A cylinder 24-6 is fixed to the lower end of the L-shaped rod 24-4 and slides within the drive frame 23-7.

[0053] The guide frame 24-3 is divided into three parts. The first and third parts prevent the L-shaped rod 24-4 from moving longitudinally when the guide rod 24-5 moves laterally. The second part allows the L-shaped rod 24-4 to move longitudinally when it moves laterally, thus achieving the oblique displacement of the L-shaped rod 24-4. Through the setting of the cylinder 24-6, when the drive frame 23-7 rotates and drives the cylinder 24-6 to move, the L-shaped rod 24-4 and the guide rod 24-5 can move, thereby causing the sliding sleeve 24-2 to move on the T-shaped plate 24-1.

[0054] When the guide post 23-9 moves from the first part of the guide frame 24-3 through the second part and into the third part, the L-shaped rod 24-4 moves up and down in the sliding sleeve 24-2. During this process, the cylinder 24-6 moves down in the drive frame 23-7 and never leaves the drive frame 23-7. It always provides force for the lateral movement of the L-shaped rod 24-4, so that the guide rod 24-5 can move in the guide frame 24-3. The L-shaped rod 24-4 moves laterally, then diagonally, and then laterally again. This causes the L-shaped plate 25 fixed on the connecting plate 24-9 to move laterally, then diagonally, and then laterally again. This causes the scraper blocks 26, 27, and 28 on the L-shaped plate 25 to move along the trajectory and make better contact with the corner of the H-beam. Then, the moving H-beam surface is passively cleaned.

[0055] A circular plate 24-7 is fixed to the upper end of the L-shaped rod 24-4. A rotating shaft 24-8 is fixed to the top of the circular plate 24-7. A connecting plate 24-9 rotates on the rotating shaft 24-8. The connecting plate 24-9 is rotatably connected to the rotating shaft 24-8 through a bearing. One end of the connecting plate 24-9 is fixedly connected to one end of the L-shaped plate 25. A fixing bolt 24-10 is threaded onto the connecting plate 24-9. The fixing bolt 24-10 can fix the connecting plate 24-9, so that the connecting plate 24-9 and the L-shaped plate 25 can be positioned after the angle position is adjusted, and will not rotate arbitrarily. This ensures the stable contact between the scraper blocks 1 26, scraper block 27, and scraper block 3 28 on the L-shaped plate 25 and the surface of the H-beam, thereby improving the cleaning effect. The circular plate 24-7 can also rotate the fixing bolt 24-10 to contact the connecting plate 24-9 after the connecting plate 24-9 is rotated and adjusted, thus fixing the connecting plate 24-9. Example

[0056] Reference Figures 3 to 16 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0057] Specifically, the feedback component 29 includes a feedback element 29-1 fixed on the L-shaped plate 25, scraper block 1 26 and scraper block 27. A pressure element 29-2 is fixed on one side of the support frame 21 and is connected to the feedback element 29-1. The pressure element 29-2 can act on the feedback element 29-1, thereby providing the scraper block 1 26 and scraper block 27 that are in contact with the H-beam, so that the scraper block 1 26 and scraper block 27 are in close contact with the right angle of the H-beam, achieving self-adaptive fit and better adapting to the cleaning of the H-beam surface.

[0058] An adjustment component 29-3 is installed on the feedback component 29-1, and a limit component 29-4 is installed on the adjustment component 29-3 and fixed to the L-shaped plate 25. With the adjustment component 29-3, in cooperation with the feedback component 29-1 and the pressure component 29-2, the scraper block 1 26 and scraper block 27 corresponding to the special area structure can be fixed, as well as all scraper blocks 1 26 and scraper blocks 27 can be fixed.

[0059] Feedback component 29-1 includes a cylinder 29-11 fixed to an L-shaped plate 25. Splined columns 29-12 are fixed on scraper block 1 26 and scraper block 27, and slide on the cylinder 29-11. Piston 1 29-13 slides inside the cylinder 29-11 and is fixed to one end of the splined column 29-12. A bend 1 29-14 is connected to the cylinder 29-11. One end of bend 1 29-14 is connected to a valve housing 29-15. A bend 29-16 is connected to the valve housing 29-15. One end of bend 29-16 is connected to an L-shaped tube 29-17. One end of L-shaped tube 29-17 is connected to a hose 29-18, and one end of hose 29-18 is connected to a pressure component 29-2. A spring piece 29-19 is fixed between the surface of piston 1 29-13 and the inner wall of cylinder 29-11.

[0060] Both the feedback component 29-1 and the pressure component 29-2 are filled with liquid. This liquid hardly compresses or stretches under pressure, which is existing technology. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here. The spline column 29-12 penetrates the cylinder 29-11 and is slidably connected to it. A sealing ring is provided between the piston 29-13 and the cylinder 29-11 and is sleeved on the surface of the piston 29-13 to seal and prevent liquid leakage.

[0061] By setting up the L-shaped tube 29-17, multiple bends 29-16 are connected to it. Then, under the action of the hose 29-18, multiple cylinders 29-11 can be connected to the pressure component 29-2. When the valve shell 29-15 corresponding to the cylinder 29-11 is not closed, the pressure component 29-2 can act on the piston 29-13 inside the cylinder 29-11 with the help of liquid. Then, through the spline column 29-12, force is applied to the scraper 26 and scraper 27 on the surface of the H-beam. It is not a simple rigid contact and can be adjusted at any time. The hose 29-18 keeps the L-shaped tube 29-17 connected to the connecting tube 29-22, without affecting the normal movement of the L-shaped tube 29-17.

[0062] By setting piston 29-13, scraper blocks 26 and 27 are squeezed and moved in contact with the surface of H-beam, causing spline column 29-12 to push piston 29-13 to move inside cylinder 29-11, thereby pushing out some of the liquid inside cylinder 29-11. Pressure component 29-2 can act on piston 29-13 with the help of liquid, thereby applying force to scraper blocks 26 and 27 on the surface of H-beam. It is not a simple rigid contact and can be adjusted at any time.

[0063] By setting the spring plate 29-19, it deforms when the piston 29-13 moves, which can provide a force to reset the scraper 26 and scraper 27 when they are separated from the H-beam surface. The premise is that the pipeline connecting the cylinder 29-11 and the pressure component 29-2 is not closed. When closed, the deformation force cannot overcome the effect of the closed liquid in the cylinder 29-11 on the piston 29-13, thereby fixing the adjusted scraper 26 and scraper 27.

[0064] The pressure component 29-2 includes an oil tank 29-21 fixed to one side of the frame 22. A connecting pipe 29-22 connects the oil tank 29-21 and the hose 29-18. A piston 29-23 slides inside the oil tank 29-21. A limit rod 29-24 slides on the oil tank 29-21, and its lower end is fixed to the top of the piston 29-23. The limit rod 29-24 passes through the oil tank 29-21 and is slidably connected to it. A spring 29-25 is sleeved on the lower surface of the limit rod 29-24, and its two ends are fixed to the inner wall of the oil tank 29-21 and the top of the piston 29-23, respectively.

[0065] A sealing sleeve is provided between piston 29-23 and oil tank 29-21, and is fitted on the surface of piston 29-23 to seal and prevent leakage. The spring 29-25 can apply pressure to piston 29-23, thereby pressurizing the liquid in oil tank 29-21, and thus acting on piston 29-13 in cylinder 29-11 through the connected pipeline.

[0066] Adjustment component 29-3 includes valve block 29-31 rotatably inside valve housing 29-15. Valve block 29-31 has a through hole. Valve block 29-31 and valve housing 29-15 form an existing ball valve device, which is prior art. The working principle of this part is also prior art, which can be clearly understood by those skilled in the art and will not be described in detail here. Valve stem 29-32 is rotatably mounted on valve housing 29-15, and one end of it is fixed to the surface of valve block 29-31. Guide groove 29-33 and guide groove 39-34 are respectively provided on the surface of valve stem 29-32, and guide groove 29-33 and guide groove 39-34 are connected.

[0067] Guide groove 29-33 is divided into three parts. The first and third parts prevent the valve stem 29-32 from rotating when the positioning pin 29-36 moves within it, thus preventing the valve block 29-31 from rotating. The second part allows the valve stem 29-32 to rotate when the positioning pin 29-36 moves within it, thus allowing the valve block 29-31 to rotate. The depth of guide groove 29-33 is greater than the depth of guide groove 39-34. When the positioning pin 29-36 is not pulled, and the movable plate 29-35 moves the positioning pin 29-36, the positioning pin 29-36 will not enter guide groove 39-34 from guide groove 29-33, but it can enter guide groove 29-33 from guide groove 39-34.

[0068] A movable plate 29-35 is fitted on the surface of the valve stem 29-32. A positioning post 29-36 slides on the movable plate 29-35, and one end of the positioning post 29-36 is engaged with the second guide groove 29-33 and the third guide groove 29-34 respectively. A pull plate 29-37 is fixed to the other end of the positioning post 29-36. A spring 29-38 is fitted on the surface of one end of the positioning post 29-36, and its two ends are fixed to the surfaces of the movable plate 29-35 and the pull plate 29-37 respectively.

[0069] With the guide groove 29-34 in place, when the valve body 29-15 needs to be closed, the pull plate 29-37 is pulled to move the positioning pin 29-36 so that one end of it disengages from the first part of the guide groove 29-33 on the valve stem 29-32. Then, the valve stem 29-32 is rotated at a certain angle, and the pull plate 29-37 is released. Under the action of the spring 29-38, one end of the positioning pin 29-36 contacts the surface of the valve stem 29-32. The valve stem 29-32 is rotated further. When one end of the positioning pin 29-36 corresponds to the guide groove 29-34, under the action of the spring 29-38, one end of the positioning pin 29-36 is inserted into the guide groove 29-34, limiting the rotation of the valve stem 29-32 and the valve block 29-31, and closing the path connecting the valve body 29-15 with the bend 1 29-14 and the bend 2 29-16.

[0070] The limiting component 29-4 includes a fixing block 29-41 fixed on the L-shaped plate 25. A lead screw 29-42 is threadedly connected to the fixing block 29-41. One end of the lead screw 29-42 rotates on the surface of the movable plate 29-35. The lead screw 29-42 passes through the fixing block 29-41 and is threadedly connected to it. The lead screw 29-42 is rotatably connected to the movable plate 29-35 through a bearing. A handle 29-43 is fixed to the other end of the lead screw 29-42.

[0071] When all valve housings 29-15 need to be closed, turn the handle 29-43 to rotate and move the screw 29-42, which in turn drives the movable plate 29-35 and the positioning pin 29-36 on it to rotate. One end of the positioning pin 29-36, which was originally located in the first part of the guide groove 29-33, enters the third part through the second part, rotating the valve stem 29-32 and the valve block 29-31, closing the corresponding valve housing 29-15. At the same time, one end of the positioning pin 29-36, which was located in the guide groove 29-34, is moved into the third part of the guide groove 29-33, so that the valve housing 29-15 is still in the closed state.

[0072] When it is necessary to open all valve housings 29-15, simply turn the handle 29-43 in the reverse direction to move the movable plate 29-35 back, thereby causing one end of the positioning pin 29-36 to enter the first part from the third part of the guide groove 29-33 through the second part, causing the valve stem 29-32 and the valve block 29-31 to rotate back, thus opening the valve housing 29-15. Example

[0073] Reference Figures 2 to 16 This is the fourth embodiment of the present invention, which is based on the first three embodiments.

[0074] Specifically, a circular frame 29-39 is fitted onto one end of the valve stem 29-32 and fixed to the surface of the valve housing 29-15. A torsion spring 29-310 is fitted onto one end of the valve stem 29-32 and located inside the circular frame 29-39. The two ends of the torsion spring 29-310 are fixed to the inner wall of the circular frame 29-39 and the surface of the valve stem 29-32, respectively. Through the setting of the torsion spring 29-310, it deforms when the valve stem 29-32 rotates, providing a force for the valve stem 29-32 and the valve block 29-31 to reset.

[0075] A limiting groove 29-311 is provided in the movable plate 29-35, and a limiting block 29-312 is fixed on the positioning column 29-36 and slides in the limiting groove 29-311. The limiting groove 29-311 and the limiting block 29-312 limit and guide the positioning column 29-36 to prevent the positioning column 29-36 from moving away from the movable plate 29-35. A knob 29-313 is fixed at one end of the valve stem 29-32. The knob 29-313 is designed to facilitate the rotation of the valve stem 29-32.

[0076] The lower scraper 210 includes a support plate 210-1 fixed to one side of the frame 22. A limit bolt 210-2 slides on the support plate 210-1. A scraper 210-3 is fixed to the upper end of the limit bolt 210-2. The scraper 210-3 has an inclined surface. With this arrangement, the H-beam is squeezed downward after contacting it. A spring 210-4 is sleeved on the surface of the limit bolt 210-2, and its two ends are fixed to the bottom of the scraper 210-3 and the top of the support plate 210-1, respectively.

[0077] By setting spring 4 210-4, the scraper 210-3 is compressed when it moves down. The elastic force generated by the spring acts on the scraper 210-3, so that the scraper 210-3 can make better contact with the bottom of the H-beam and improve the cleaning effect. The scraper 210-3 is guided and limited by the limit bolt 210-2 to ensure that it is vertical.

[0078] A cover 212 is fixed on the frame 22, which covers the corresponding structure on the cleaning mechanism 2 and provides protection.

[0079] In use, when the welded H-beam is conveyed to the drive component 23, force is applied to it, and the H-beam contacts and is squeezed by the roller 23-2, causing it to move downward. This causes the slider 23-1 and the vertical rod 23-4 to move downward, which in turn causes the guide post 23-9 to move from the first part of the guide groove 23-8 on the sleeve 23-6 to the second part, causing the sleeve 23-6 to rotate. This causes the drive frame 23-7 to rotate, driving the transmission component 24. The transmission component 24 drives the L-shaped plate 25 on it to move closer to the H-beam, which in turn causes the scraper blocks 26, 27, and 38 on it to move closer to the vertically placed H-beam and contact the corner area below the vertically placed H-beam.

[0080] When scraper blocks 26 and 27 come into contact with the surface of the H-beam, they are squeezed and moved, causing the splined column 29-12 to push the piston 29-13 to move within the cylinder 29-11. This pushes out some of the liquid inside the cylinder 29-11. The pressure component 29-2, with the help of the liquid, acts on the piston 29-13, which in turn applies force to the scraper blocks 26 and 27 on the surface of the H-beam. This is not a simple rigid contact; it can be adjusted at any time to ensure close and adaptive contact with the right-angled surface of the H-beam, improving the cleaning effect and flexibility. Furthermore, it can be adjusted according to the actual condition of the H-beam to meet different usage requirements.

[0081] At the same time, after the H-beam comes into contact with the scraper 210-3, it is squeezed and moved downward. When the scraper 210-3 moves downward, it compresses the spring 210-4. The elastic force generated by the spring acts on the scraper 210-3, so that the scraper 210-3 can make better contact with the bottom of the H-beam and improve the cleaning effect.

[0082] In summary, the cleaning mechanism 2 can clean the surface of the steel profile being straightened by the mobile conveyor, dynamically fitting the surface of the H-beam. Compared with existing technologies, it can simultaneously remove weld slag, adhesive residue, and other attachments, preventing impurities from affecting the straightening accuracy. The scraper adopts a multi-stage sliding structure, which can adapt to different thicknesses of wing plates and weld protrusions. The front-mounted design can prevent hard weld slag from entering the straightening roller area, reducing the risk of abnormal wear and surface indentation of the pressure roller, and extending the service life of the roller. The feedback component 29 monitors the scraping resistance in real time and feeds it back to the drive system through the hydraulic linkage of the cylinder 29-11, piston 29-13, and pressure component 29-2. Compared with existing technologies, it automatically adjusts the scraping force to avoid excessive pressure that could damage the steel surface.
