Description

Technical Field

[0001] This invention relates to the field of steel processing technology, specifically to a deformation correction device for welding H-shaped steel columns. Background Technology

[0002] H-beams are an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. Because all parts of an H-beam are arranged at right angles, it has advantages such as strong bending resistance, simple construction, cost savings, and light structural weight in all directions, and has been widely used. During the processing of H-beams, the flanges are prone to bending deformation due to concentrated heating at the weld seams. To facilitate use, the bending needs to be corrected.

[0003] Existing straightening devices typically use pressure rollers to press the surface of the H-beam and support devices to hold the flanges in place. The H-beam then moves horizontally between the pressure rollers, while the support devices remain fixed during the straightening process. Therefore, when gaps appear between the support devices and the flanges, the pressure rollers cannot flatten the bends, thus reducing the straightening quality. Furthermore, the H-beams are already at a high temperature after processing, and deformation at the flanges during straightening causes the H-beam temperature to rise further, making it difficult for workers to operate. Summary of the Invention

[0004] The purpose of this invention is to provide a deformation straightening device for welding H-beam steel columns. This device utilizes a reciprocating moving component and a limiting component to drive a transmission component in a reciprocating motion. This allows a supporting component to maintain its supporting effect while reciprocating to compress the H-beam steel. In conjunction with a pressing component, it prevents gaps from causing a reduction in straightening quality, thus improving the straightening quality.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] I. This invention uses a slider to swing back and forth along the sliding opening, which drives the adjustment box and rollers to move back and forth in the middle of the H-beam. The rollers roll back and forth at the flange of the H-beam and cooperate with the pressing roller to roll and flatten the bend, avoiding gaps that would reduce the straightening quality. In addition, the rollers can reduce wear on the flange and improve product quality.

[0033] Second, in this invention, during the straightening process of H-beams, deformation occurs at the flanges, causing the temperature of the H-beams to rise and making them difficult for workers to operate. At this time, by starting a fan to blow air onto the surface of the H-beams, the airflow speed at that location is accelerated, so that the heat emitted from the surface of the H-beams can be quickly exchanged with the outside air, thereby accelerating the cooling speed of the H-beams, preventing burns to workers, and facilitating subsequent operations.

[0034] Third, the H-beams of this invention are prone to producing steel slag on their surface during processing. Therefore, during use, the rotating shaft swings back and forth, driving the brush plate to swing back and forth, so that the brush bristles can remove the steel slag from the surface of the H-beams, preventing the steel slag from pressing onto the surface of the H-beams during subsequent pressing and straightening, thus preventing dents and improving product quality.

[0035] Fourth, in the initial state, the connecting block abuts against the surface of the moving plate by the elastic force of the second spring, so that the annular toothed rack of the second rack remains engaged, and the frame and the connecting block cannot move in the initial state, thereby limiting the turntable and preventing the turntable from shaking when the device is stopped, thus improving the stability of the device during use.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1:

[0046] Please see Figures 1 to 7 This embodiment provides a deformation correction device for welding H-shaped steel columns, comprising:

[0047] The conveyor belt 2 has an H-beam 1 placed on its surface. The conveyor belt 2 includes a drive shaft 3 and a motor 35 that drives the drive shaft to rotate. Fixed plates 4 are fixedly installed on both sides of one end of the conveyor belt 2. A control switch is provided on the surface of the fixed plates 4. A movable plate 5 is slidably connected between the two fixed plates 4 through a slide groove 41. The surface of the movable plate 5 has a through hole for the rotating shaft 7 to pass through and rotate with it. A pressing component is provided at the bottom of the movable plate 5. In use, the H-beam 1 is placed on the surface of the conveyor belt 2. Then, the movable plate 5 is moved to drive the pressing component to press on the surface of the H-beam 1 to correct the bending of the flange of the H-beam 1. At the same time, the motor 35 is started to make the conveyor belt 2 operate, which drives the H-beam 1 to move, thereby completing the correction of the entire steel column.

[0048] The support component is located at the bottom of the movable plate 5 and is slidably connected to it. When in use, the support component extends into the middle of the H-beam 1 to support the upper and lower flanges of the H-beam 1, preventing the flanges from being flattened by the pressing component due to different bending angles, thus ensuring the straightening quality.

[0049] The first transmission component is set on the surface of the rotating shaft 7 and is used to drive the support component to slide at the bottom of the moving plate 5. In use, the support component is driven to extend into the middle of the H-beam 1 by sliding the moving plate 5, so as to facilitate the support of the H-beam 1.

[0050] Transmission component two is disposed on the surface of fixed plate 4 and connected to drive shaft 3 via transmission assembly. Transmission component two includes reciprocating moving assembly, the surface of which is provided with limiting components to drive or limit the movement of transmission component one. In use, by starting motor 35, the water conveying belt 2 is driven to operate, and the drive shaft 3 is rotated. The rotation of drive shaft 3, through the action of transmission assembly, drives the reciprocating moving assembly to move. Through the movement of reciprocating moving assembly, through the action of limiting components, the transmission component one is driven to reciprocate, so that the support component reciprocates to compress the H-beam 1 while maintaining the support effect, and cooperates with pressing component to avoid gaps that would reduce the straightening quality, thereby improving the straightening quality.

[0051] The cooling component, located at the bottom of the reciprocating moving assembly, is used to cool the straightening section of the H-beam 1. During use, the surface temperature of the H-beam 1 is high after processing, making it difficult for workers to operate. Furthermore, during the straightening process, deformation occurs at the flanges of the H-beam 1. During deformation, mechanical energy is converted into internal energy of the H-beam 1, increasing the internal energy and raising the temperature, thus causing the temperature of the H-beam 1 to rise further. The cooling component cools the straightening section of the H-beam 1, facilitating subsequent operations. The reciprocating moving assembly also increases the working range of the cooling component, improving the cooling efficiency.

[0052] The driving component is set on the surface of the fixed plate 4 and connected to the movable plate 5. In use, the driving component drives the movable plate 5 to move vertically, so that the pressing component presses on the surface of the H-beam 1.

[0053] Example 2, based on the above examples:

[0054] Furthermore, the support component in Embodiment 1 is disclosed: the support component includes:

[0055] Two sets of symmetrically distributed sliders 10 are provided. The surface of the movable plate 5 is provided with a sliding opening 11 for the sliders 10 to pass through and slide in connection with it. A telescopic plate 12 is fixedly connected to the lower surface of the sliders 10.

[0056] The support cylinder 13 is fixedly connected to the bottom surface of the telescopic plate 12. The inner wall of the support cylinder 13 is slidably connected to the support rod 131. A spring 132 is fixedly connected between the surface of the support rod 131 and the inner wall of the support cylinder 13.

[0057] The regulating box 14 has a partition inside. Hydraulic cylinders 15 are fixedly installed on both the upper and lower sides of the partition. The drive part of the hydraulic cylinders 15 is fixedly connected to a backing plate 16. Rollers 17 are provided on the surface of the backing plate 16.

[0058] More specifically, in this embodiment, the transmission component 1 drives the slider 10 to slide along the sliding opening 11, causing the two telescopic plates 12 to move closer together. The two telescopic plates 12 move closer together, and the support cylinder 13 and support rod 131 cause the adjusting box 14 to extend into the middle of the H-beam 1. Then, the hydraulic cylinder 15 is activated, causing the roller 17 to abut against the upper and lower flanges of the H-beam 1. Figure 1 and Figure 3 As shown, the hydraulic cylinder 15 can adapt to H-beams 1 of different thicknesses, ensuring that the roller 17 can stably abut against the steel plate surface, thus guaranteeing the quality of the straightening.

[0059] By using the support rod 131 and spring 132, since the adjustment box 14 is initially inserted into the middle of the H-beam 1 by manually rotating the turntable 6, and the distance that drives the adjustment box 14 and roller 17 to reciprocate within the H-beam 1 remains constant, this application utilizes the compressibility of spring 132 to alleviate the excess travel and prevent the roller 17 from jamming when moving towards the H-beam 1.

[0060] Example 3, based on the above examples:

[0061] Furthermore, the transmission component 1 in Embodiment 1 is disclosed: the transmission component 1 includes a turntable 6 and a sliding column 8. The turntable 6 is fixedly connected to the surface of the rotating shaft 7. There are two sliding columns 8, which are fixedly connected to the upper surfaces of the two sliders 10 respectively. The surface of the turntable 6 is provided with an arc-shaped opening 9 for the sliding column 8 to pass through and slide in connection with it.

[0062] More specifically, in this embodiment, the limiting component releases the limiting of the turntable 6, and then the turntable 6 is rotated. By rotating the turntable 6, the sliding column 8 slides along the inner wall of the arc-shaped opening 9. During the sliding process, the inner wall of the arc-shaped opening 9 presses the sliding column 8 to move. By moving the sliding column 8, the slider 10 is driven to slide along the sliding opening 11.

[0063] Example 4, based on the above examples:

[0064] Furthermore, the transmission component two, the reciprocating motion assembly, and the transmission assembly in Embodiment 1 are disclosed: Transmission component two includes:

[0065] The rotating rod 23 has a through hole on the surface of the fixing plate 4 for the rotating rod 23 to pass through and be rotatably connected to it on a fixed axis. An incomplete gear 24 is fixedly connected to the surface of the rotating rod 23.

[0066] The reciprocating moving assembly includes a frame 25. The surface of the fixing plate 4 is provided with a slide groove 42 for the frame 25 to extend into and slide in connection with it. Two sets of rack rows 26 are symmetrically arranged on the inner wall of the frame 25. Both sets of rack rows 26 intermittently mesh with the incomplete gear 24.

[0067] The transmission assembly includes a belt drive mechanism 22, and the rotating rod 23 is connected to the drive shaft 3 via the belt drive mechanism 22.

[0068] More specifically, in this embodiment, the drive shaft 3 rotates, and through the belt transmission mechanism 22, the rotating rod 23 and the incomplete gear 24 rotate. Through the rotation of the incomplete gear 24 and its intermittent meshing with the two sets of racks 26, the frame 25 reciprocates. Through the reciprocating movement of the frame 25, the cooling component and the limiting component reciprocate, thereby increasing the working range of the cooling component.

[0069] Example 5, based on the above examples:

[0070] Furthermore, the limiting component in Embodiment 1 is disclosed: the limiting component includes:

[0071] Connecting block 29, rack row 24 is fixedly connected to the surface of connecting block 29, and annular rack 33 is provided on the outer ring surface of turntable 6, rack row 24 meshes with annular rack 33.

[0072] Connecting rod 28 is fixedly connected to the surface of connecting block 29. The end face of connecting rod 28 has a groove for connecting rod 27 to extend into. A spring 281 is fixedly connected between connecting rod 27 and the groove. The end of connecting rod 27 is fixedly connected to the side of frame 25. Spring 281 is in a stretched state in the initial state of the device.

[0073] More specifically, in this embodiment, the connecting block 29 abuts against the surface of the moving plate 5 by the elastic force of the second spring 281, and at this time, the second rack 34 meshes with the annular toothed rack 33 on the surface of the turntable 6. Therefore, the frame 25 and the connecting block 29 cannot move. The second rack 34 limits the turntable 6 to prevent the turntable 6 from shaking when the device is stopped, thus improving the stability of the device during use. During use, the frame 25 moves back and forth, and the connecting block 29 moves back and forth through the action of the second connecting rod 27 and the first connecting rod 28. The reciprocating movement of the connecting block 29 drives the second rack 34 to move back and forth, and the reciprocating movement of the second rack 34 drives the turntable 6 to swing back and forth. During the reciprocating swing of the turntable 6, the sliding column 8 drives the slider 10 to move back and forth along the sliding opening 11, and the telescopic plate 12 and the support cylinder 13 drive the adjusting box 14 and the roller 17 to move back and forth in the middle of the H-beam 1.

[0074] By having the roller 17 roll back and forth on the flange of the H-beam 1 and cooperate with the pressing roller 19, the curved part can be rolled flat, further reducing wear and extending the service life of the device. After the correction is completed, the device is restored to its initial state for subsequent correction work.

[0075] Example 6, based on the above examples:

[0076] Furthermore, the cooling component in Embodiment 1 is disclosed: the cooling component includes a fan 32, and a mounting bracket 31 is fixedly connected to the bottom of the frame 25, and the fan 32 is fixedly mounted on the mounting bracket 31.

[0077] More specifically, in this embodiment, by activating the fan 32, air is blown onto the surface of the H-beam 1, accelerating the airflow speed at that location and increasing the heat exchange speed of the external air of the H-beam 1, preventing workers from being burned. Furthermore, by reciprocating the frame 25, the working range of the fan 32 is increased, accelerating the cooling speed and reducing the waiting time for cooling.

[0078] Example 7, based on the above examples:

[0079] Furthermore, in order to facilitate the removal of steel slag from the surface of the H-beam 1, a brush plate 20 is fixedly connected to the surface of the rotating shaft 7 and below the moving plate 5, and brush bristles are provided at the bottom of the brush plate 20.

[0080] More specifically, in this embodiment, steel slag is easily generated on the surface of the steel plate during processing. The turntable 6 swings back and forth, and the rotating shaft 7 swings back and forth, driving the brush plate 20 to swing back and forth. The brush plate 20 swings back and forth, driving the bristles to brush away the steel slag on the surface of the H-beam 1, preventing the steel slag from pressing on the surface of the H-beam 1 during subsequent pressing and straightening, thus preventing dents from appearing on the surface of the H-beam 1 and improving the quality of the product.

[0081] Example 8, based on the above examples:

[0082] Furthermore, the pressing component in Embodiment 1 is disclosed: the pressing component includes a pressure plate 18, which is rotatably connected to the bottom of the rotating shaft 7 and fixedly connected to the bottom of the moving plate 5 through an L-shaped plate 21. A pressing roller 19 is provided on the lower surface of the pressure plate 18.

[0083] More specifically, in this embodiment, the downward movement of the moving plate 5 drives the rotating shaft 7 and the pressure plate 18 to move downward. The downward movement of the pressure plate 18 drives the pressing roller 19 to press against the surface of the H-beam 1. During the operation of the conveyor belt 2, the H-beam 1 is moved. During the movement of the H-beam 1, the pressing roller 19 is rotated by friction while maintaining the pressing pressure. The pressing roller 19 rolls and squeezes the flange of the H-beam 1, avoiding continuous friction between surfaces during the straightening process, reducing wear, improving the finished product quality of the H-beam 1 and the service life of the device.

[0084] Example 9, based on the above examples:

[0085] Furthermore, the driving component in Embodiment 1 is disclosed: the driving component includes two sets of symmetrically distributed hydraulic cylinders 30, the hydraulic cylinders 30 are fixedly mounted on the surface of the fixed plate 4, and the driving part of the hydraulic cylinders 30 is fixedly connected to the bottom of the moving plate 5.

[0086] More specifically, in this embodiment, the moving plate 5 is driven to move vertically along the slide groove 41 by activating the second hydraulic cylinder 30, and the stability of the moving plate 5 during movement is improved by setting two sets of symmetrically distributed hydraulic cylinders 30.

[0087] Working principle: When using this deformation correction device for welding H-beam steel columns, first place the H-beam 1 on the surface of the conveyor belt 2 and align one end of the H-beam 1 with the fixed plate 4. In the initial state, the second spring 281 is in a stretched state, and the connecting block 29 abuts against the surface of the moving plate 5 through the elastic force of the second spring 281, and drives the second rack 34 to mesh with the annular toothed rack 33 on the surface of the turntable 6. Since the conveyor belt is stopped at this time, the drive shaft 3 stops rotating, so the frame 25 and the connecting block 29 cannot move. Thus, the second rack 34 limits the turntable 6, preventing the turntable 6 from shaking when the device is stopped, wasting subsequent adjustment time, and improving the stability of the device during use.

[0088] After the H-beam 1 is placed on the surface of the conveyor belt 2, the connecting block 29 is pulled upwards manually, causing the rack and pinion 34 to disengage from the annular rack and pinion 33. Then, the turntable 6 is rotated. The rotation of the turntable 6 causes the arc-shaped opening 9 on the surface to rotate. During the rotation of the turntable 6, the sliding column 8 slides along the inner wall of the arc-shaped opening 9. During the sliding process, the inner wall of the arc-shaped opening 9 presses the sliding column 8 to move. The movement of the sliding column 8 causes the slider 10 to slide along the sliding opening 11. The sliding of the slider 10 along the sliding opening 11 causes the two telescopic plates 12 to move closer to each other. The two telescopic plates 12 moving closer to each other causes the adjusting box 14 to extend into the middle of the H-beam 1. Then, the hydraulic cylinder 15 is activated, and the abutment plate 16 drives multiple sets of rollers 17 to abut against the upper and lower flanges of the H-beam 1 respectively. At this time, if Figure 1 and Figure 3As shown, hydraulic cylinder 15 can adapt to H-beams 1 of different thicknesses, ensuring that roller 17 can stably abut against the surface of the steel plate, thus guaranteeing the quality of straightening. After roller 17 abuts against the upper and lower flanges, the turntable 6 can be stopped and the connecting block 29 can be released. The connecting block 29 continues to adhere to the surface of the moving plate 5 through the elastic restoring force of spring 281, while the rack rack 34 resumes its meshing relationship with the annular rack 33. Then, hydraulic cylinder 30 is activated, and the drive part of hydraulic cylinder 30 retracts, driving the moving plate 5 to move downward towards the H-beam 1. During the downward movement of the moving plate 5, the connecting block 29 always remains in contact with the surface of the moving plate 5 through the tension of spring 281. As the moving plate 5 moves downward, it drives the rotating shaft 7 and the pressure plate 18 to move downward. As the pressure plate 18 moves downward, it drives the pressing roller 19 to press against the surface of the H-beam 1, thus straightening the easily bent parts of the flange of the H-beam 1.

[0089] Then, the hydraulic cylinder 30 is closed, and the motor 35 is started to drive the conveyor belt 2. During the operation of the conveyor belt 2, the H-beam 1 is moved. During the movement of the H-beam 1, the pressing roller 19 is driven to rotate while maintaining the pressing pressure through friction. The pressing roller 19 rolls and squeezes the flange of the H-beam 1, avoiding continuous friction between surfaces during the straightening process, reducing friction wear on the device and the H-beam 1, improving the finished product quality of the H-beam 1 and the service life of the device.

[0090] During the operation of conveyor belt 2, drive shaft 3 keeps rotating. The rotation of drive shaft 3, through belt drive mechanism 22, drives rotating rod 23 to rotate. Rotating rod 23 drives incomplete gear 24 to rotate. Through intermittent meshing with two sets of racks 26, incomplete gear 24 drives frame 25 to reciprocate along slide groove 42. This reciprocating movement of frame 25 along slide groove 42 drives the fan 32 below frame 25 to reciprocate. Because the surface temperature of H-beam 1 is high after processing, it is difficult for workers to operate, and during the straightening process, the flange of H-beam 1... During deformation, mechanical energy is converted into internal energy of the H-beam 1. Increased internal energy leads to a rise in temperature, causing the temperature of the H-beam 1 to rise further. At this point, the fan 32 is activated, blowing air onto the surface of the H-beam 1 to accelerate airflow and rapidly exchange heat between the surface of the H-beam 1 and the outside air, thus accelerating the cooling rate of the H-beam 1 and preventing burns to workers. Furthermore, the reciprocating movement of the frame 25 increases the working range of the fan 32, improving cooling efficiency. The reciprocating movement of the frame 25, along with the action of connecting rods 27 and 28, drives the connecting... Block 29 reciprocates, which in turn drives rack 24 to reciprocate. The reciprocating movement of rack 29, in turn, drives turntable 6 to oscillate. The oscillation of turntable 6, in turn, drives brush plate 20 to oscillate. Brush plate 20, which had already rotated during the previous rotation of turntable 6, is now positioned in the middle of H-beam 1. The oscillation of brush plate 20 causes the bristles to remove slag from the surface of H-beam 1, preventing dents from appearing on the surface during subsequent pressing and straightening, thus improving product quality. During the reciprocating oscillation of turntable 6, slide block 10 reciprocates along slide opening 11 via slide column 8. The device moves and, through the telescopic plate 12 and the support cylinder 13, drives the adjusting box 14 and the roller 17 to reciprocate in the middle of the H-beam 1. The roller 17 rolls back and forth at the flange of the H-beam 1 and cooperates with the pressing roller 19 to roll and flatten the bend, avoiding gaps that would reduce the straightening quality and further reduce wear, thus extending the service life of the device. After straightening is completed, the motor 35 is turned off and the hydraulic cylinder 2 30 is started to push the moving plate 5 to its original position. Then the connecting block 29 is pulled up, and the turntable 6 is rotated to return it to its original position. Then the H-beam 1 is flipped over to straighten the other side.
