Description

Technical Field

[0001] This application relates to the field of steel structure production technology, and in particular to H-beam straightening devices and steel structure production lines. Background Technology

[0002] H-beams, box girders, and other steel structures are widely used in various industries such as construction, automobile manufacturing, and aerospace construction, and the demand for steel structures has remained consistently high.

[0003] In the steel structure production process, straightening machines are needed to straighten workpieces. However, existing straightening machines are difficult to straighten workpieces of different sizes and specifications. Furthermore, when straightening a workpiece, it can only straighten one side. After one side is straightened, the straightening machine needs to be moved to the other side of the workpiece for straightening. This results in the need for multiple straightening machines to achieve a one-time straightening of the workpiece. Summary of the Invention

[0004] This application aims to solve at least one of the technical problems existing in the related art. To this end, this application proposes an H-beam straightening device that enables simultaneous straightening of both sides of the workpiece, achieving one-time straightening of the workpiece without the need for multiple straightening devices, simplifying the straightening operation of the workpiece, saving a lot of time, and allowing the height and width of the straightening device to be adjusted, so that the straightening device can straighten workpieces of different sizes.

[0005] This application also proposes a steel structure production line.

[0006] The H-beam straightening device according to the first aspect of this application includes:

[0007] Correction mounting bracket;

[0008] At least two correction mechanisms are slidably mounted on the correction mounting frame, and the two correction mechanisms are arranged opposite to each other;

[0009] A width adjustment component is installed on the orthodontic mounting frame and connected to the orthodontic mounting frame. The width adjustment component is used to move the two orthodontic mechanisms closer to or further apart from each other.

[0010] The straightening mechanism includes a straightening seat, a height adjustment component, a straightening component, and a straightening transmission component. The straightening seat and the height adjustment component are both mounted on the straightening mounting frame. The height adjustment component is connected to the straightening seat and is used to drive the straightening seat to move up and down. The straightening component is mounted on the straightening seat and is adapted to straighten the workpiece. The straightening transmission component is connected to the straightening seat and is used to drive the workpiece to move.

[0011] According to the H-beam straightening device of this application embodiment, one side of the workpiece is located at the straightening component of one straightening mechanism, and the other side of the workpiece is located at the straightening component of another straightening mechanism. The two straightening components can straighten both sides of the workpiece respectively. The workpiece also contacts the straightening transmission component, which can drive the workpiece to move, allowing the workpiece to automatically move to the next station. When it is necessary to straighten workpieces of different sizes, the two straightening mechanisms can be moved relative to each other by the width adjustment component according to the actual size of the workpiece, thereby adjusting the distance between the two straightening mechanisms and adjusting the straightening width so that the width between the two straightening mechanisms matches the workpiece. The height adjustment component drives the straightening seat to move up and down, and since the straightening transmission component and the straightening component are both installed and connected to the straightening seat, the straightening component and the straightening transmission component will also move up and down accordingly, so that the straightening component can maintain accurate straightening of the workpiece, and the straightening transmission component can drive the workpiece to move, thereby adjusting the straightening height. This application enables simultaneous correction of both sides of a workpiece, eliminating the need for multiple correction devices to achieve one-time correction of the workpiece. This simplifies the correction operation, saves a significant amount of time, and allows for adjustments to the height and width of the correction device, enabling it to correct workpieces of different sizes.

[0012] According to one embodiment of this application, the width adjustment assembly includes a width adjustment drive, a lead screw, and two nut seats. The width adjustment drive is mounted on the straightening mounting bracket, and the lead screw is connected to the width adjustment drive.

One of the nut seats is fixedly mounted on one of the straightening mechanisms, and the other nut seat is fixedly mounted on the other straightening mechanism. The threads of the two nut seats are opposite, and both nut seats are threadedly connected to the lead screw.

[0013] According to one embodiment of this application, one of the correction mechanisms is connected to the correction mounting frame via a first slider, and the other correction mechanism is connected to the correction mounting frame via a second slider. Both the first slider and the second slider can slide relative to the correction mounting frame, and the bottom surfaces of the first slider and the second slider are on the same plane.

[0014] According to one embodiment of this application, the width adjustment assembly includes a first width adjustment driver and a second width adjustment driver.

The first width adjustment driver is connected to one of the correction mechanisms and is used to drive one of the correction mechanisms to move along the correction mounting frame. The second width adjustment driver is connected to the other correction mechanism and is used to drive the other correction mechanism to move along the correction mounting frame.

The two straightening and positioning seats are arranged opposite to each other, and both straightening and positioning seats are connected to the straightening and positioning drive. The straightening and positioning drive is used to drive the two straightening and positioning seats to move closer to or further away from each other.

[0017] According to one embodiment of this application, one of the straightening and positioning seats is provided with at least one straightening and positioning roller on the side wall facing the other straightening and positioning seat, and the straightening and positioning roller is rotatable relative to the straightening and positioning seat.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0042] The following is combined with Figures 1 to 7 This application describes the H-beam straightening device and steel structure production line.

[0043] According to the embodiments of the first aspect of this application, such as Figure 1 and Figure 2 As shown, the H-beam straightening device includes:

[0044] Correction mounting bracket 510;

[0045] At least two correction mechanisms 520 are slidably mounted on the correction mounting frame 510, and the two correction mechanisms 520 are arranged opposite to each other;

[0046] Width adjustment component 530 is installed on the correction mounting frame 510. Width adjustment component 530 is connected to correction mounting frame 510. Width adjustment component 530 is used to drive two correction mechanisms 520 to move closer or further apart.

[0047] The straightening mechanism 520 includes a straightening seat 521, a height adjustment component 522, a straightening component 523, and a straightening transmission component 524. The straightening seat 521 and the height adjustment component 522 are both mounted on the straightening mounting frame 510. The height adjustment component 522 is connected to the straightening seat 521 and is used to drive the straightening seat 521 to move up and down. The straightening component 523 is mounted on the straightening seat 521 and is suitable for straightening the workpiece. The straightening transmission component 524 is connected to the straightening seat 521 and is used to drive the workpiece to move.

[0048] According to the H-beam straightening device of this application embodiment, one side of the workpiece is located at the straightening component 523 of one straightening mechanism 520, and the other side of the workpiece is located at the straightening component 523 of another straightening mechanism 520. The two straightening components 523 can straighten both sides of the workpiece respectively. The workpiece also contacts the straightening transmission component 524, so that the straightening transmission component 524 can drive the workpiece to move, allowing the workpiece to automatically move to the next station. When workpieces of different sizes need to be straightened, the width adjustment component 530 can drive the two straightening mechanisms 520 to move relative to each other according to the actual size of the workpiece, thereby adjusting the distance between the two straightening mechanisms 520 and matching the width between them with the workpiece. The height adjustment component 522 will drive the straightening seat 521 to move up and down. Since the straightening transmission component 524 and the straightening component 523 are both installed and connected to the straightening seat 521, the straightening component 523 and the straightening transmission component 524 will also move up and down accordingly. This allows the straightening component 523 to maintain accurate straightening of the workpiece, and the straightening transmission component 524 to move the workpiece, thus adjusting the straightening height. In other words, this application enables simultaneous straightening of both sides of the workpiece, achieving one-time straightening of the workpiece without the need for multiple straightening devices. This simplifies the straightening operation, saves a lot of time, and allows for adjustment of the height and width of the straightening device, enabling it to straighten workpieces of different sizes.

[0049] Understandably, when no workpiece correction is required, the width adjustment component 530 can move the two correction mechanisms 520 away from each other, leaving enough space between the two correction mechanisms 520 for the workpiece to pass through. In other words, the workpiece can pass directly between the two correction mechanisms 520 without correction.

[0050] Understandably, when this application is applied to the straightening of H-beams, the flange on one side of the H-beam is moved between the straightening roller 5231 and the straightening transmission member 524 of the straightening component 523 of one straightening mechanism 520, and the flange on the other side of the H-beam is moved between the straightening roller 5231 and the straightening transmission member 524 of the straightening component 523 of another straightening mechanism 520. The web is located between the two straightening mechanisms 520. Then, the straightening roller 5231 of the straightening component 523 is controlled to move towards the straightening transmission member 524, thereby achieving the straightening of the flange of the H-beam.

[0051] It is understandable that a passage space is formed at the straightening mounting bracket 510, where the workpiece can move. The straightening assembly 523 and the straightening transmission component 524 are located within the passage space to straighten the workpiece within the passage space.

[0052] It is understandable that the straightening component 523 can perform the straightening operation on the workpiece independently, or it can cooperate with the straightening transmission component 524 to perform the straightening operation on the workpiece.

[0053] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the width adjustment assembly 530 includes a width adjustment drive 531, a lead screw 532, and two nut seats 533. The width adjustment drive 531 is mounted on the straightening mounting bracket 510. The lead screw 532 is connected to the width adjustment drive 531. The width adjustment drive 531 is used to drive the lead screw 532 to rotate. One nut seat 533 is fixedly mounted on one of the straightening mechanisms 520, and the other nut seat 533 is fixedly mounted on the other straightening mechanism 520. The threads of the two nut seats 533 are opposite, and both nut seats 533 are threadedly connected to the lead screw 532.

[0054] It is understandable that the width adjustment drive 531 drives the lead screw 532 to rotate. When the lead screw 532 rotates, it will drive the nut seat 533 to move. Since the threads of the two nut seats 533 are opposite, when the lead screw 532 rotates, the two nut seats 533 will move in different directions. Since the two nut seats 533 are connected to the two straightening mechanisms 520 respectively, the two straightening mechanisms 520 will move in different directions, thereby realizing the automatic control of the two straightening mechanisms 520 to move closer to each other or further away from each other.

[0055] An exemplary width adjustment drive 531 is, for example, a motor.

[0056] In one embodiment of this application, one correction mechanism 520 is connected to the correction mounting frame 510 via a first slider, and the other correction mechanism 520 is connected to the correction mounting frame 510 via a second slider. Both the first slider and the second slider can slide relative to the correction mounting frame 510, and the bottom surfaces of the first slider and the second slider are on the same plane.

[0057] It is understandable that the straightening mechanism 520 and the straightening mounting bracket 510 are connected by sliders, allowing the straightening mechanism 520 to slide along the straightening mounting bracket 510, so that the width adjustment component 530 can move the two straightening mechanisms 520 closer or further apart. At the same time, the bottom surfaces of the first slider and the second slider are on the same plane, which allows the two straightening mechanisms 520 to be at the same height.

[0058] It is understandable that the number of the first and second sliders can be increased or decreased according to the actual situation. For example, there can be two of each type of slider.

[0059] In one embodiment of this application, the width adjustment component 530 includes a first width adjustment driver and a second width adjustment driver. Both the first width adjustment driver and the second width adjustment driver are mounted on the straightening mounting frame 510. The first width adjustment driver is connected to one of the straightening mechanisms 520 and is used to drive one of the straightening mechanisms 520 to move along the straightening mounting frame 510. The second width adjustment driver is connected to the other straightening mechanism 520 and is used to drive the other straightening mechanism 520 to move along the straightening mounting frame 510.

[0060] It is understandable that the first width adjustment drive can move one of the correction mechanisms 520, and the second width adjustment drive can move the other correction mechanism 520, thereby adjusting the distance between the two correction mechanisms 520 and realizing the adjustment of the correction width.

[0061] It is understandable that the movement of the two straightening mechanisms 520 is controlled independently, and the movement of the two straightening mechanisms 520 does not affect each other. This allows for adjustment of the center position between the two straightening mechanisms 520. Therefore, during the straightening operation, if the workpiece fails to be centered between the two straightening mechanisms 520, the movement of each straightening mechanism 520 can be controlled independently to change the center position of the two straightening mechanisms 520, ensuring that the workpiece is centered between the two straightening mechanisms 520 and guaranteeing the smooth progress of the straightening operation.

[0062] For example, the first width adjustment drive and the second width adjustment drive are, for example, hydraulic cylinders or pneumatic cylinders.

[0063] In one embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the straightening mounting frame 510 has an operating space 511, and two straightening mechanisms 520 are located on both sides of the operating space 511. The H-beam straightening device includes a straightening and positioning adjustment component 540, which is installed on one side of the straightening mounting frame 510. The straightening and positioning adjustment component 540 straightens the workpiece entering the operating space 511 and adjusts the position of the workpiece.

[0064] Understandably, before the workpiece enters the operating space 511, it will first pass through the straightening and positioning adjustment component 540. The straightening and positioning adjustment component 540 will straighten the workpiece and adjust its position so that the workpiece can enter the operating space 511 in the center. This avoids any deviation when the workpiece enters the operating space 511, which would prevent the straightening operation from being carried out smoothly. This ensures that both sides of the workpiece can be located at the two straightening mechanisms 520 respectively, so that the two straightening mechanisms 520 can perform straightening operations on both sides of the workpiece at the same time.

[0065] In one embodiment of this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the straightening and positioning adjustment assembly 540 includes a straightening and positioning frame 541, a straightening and positioning drive 542, and two straightening and positioning seats 543. The straightening and positioning drive 542 is mounted on the straightening and positioning frame 541, and the two straightening and positioning seats 543 are slidably connected to the straightening and positioning frame 541. The two straightening and positioning seats 543 are arranged opposite to each other, and both straightening and positioning seats 543 are connected to the straightening and positioning drive 542. The straightening and positioning drive 542 is used to drive the two straightening and positioning seats 543 to move closer to or further away from each other.

[0066] It is understandable that the straightening and positioning frame 541 is installed on one side of the straightening mounting frame 510, so that the straightening and positioning frame 541 is located at the entrance of the operating space 511. That is, the workpiece will pass through the straightening and positioning frame 541 before entering the operating space 511. Before the workpiece moves onto the straightening and positioning frame 541, the straightening and positioning drive 542 can drive the two straightening and positioning seats 543 to move away from each other, so that the workpiece can move onto the straightening and positioning frame 541, that is, it is convenient for the workpiece to move between the two straightening and positioning seats 543. Then, the straightening and positioning drive 542 drives the two straightening and positioning seats 543 to move closer to each other until the two straightening and positioning seats 543 clamp the workpiece, so that the workpiece is in a centered position. While clamping the workpiece, the workpiece can be straightened, so that the workpiece enters the operating space 511 in a straightened and centered position.

[0067] For example, the centering and positioning drive 542 is connected to the centering and positioning nut on the centering and positioning seat 543 via the centering and positioning screw, and the threads of the centering and positioning nuts on the two centering and positioning seats 543 are opposite. When the centering and positioning drive 542 drives the centering and positioning screw to rotate, the two centering and positioning seats 543 will move in different directions.

[0068] For example, the straightening and positioning drive 542 is a motor.

[0069] In one embodiment of this application, such as Figure 3 As shown, one of the straightening and positioning seats 543 has at least one straightening and positioning roller 544 on its side wall facing the other straightening and positioning seat 543, and the straightening and positioning roller 544 can rotate relative to the straightening and positioning seat 543.

[0070] Understandably, when the two straightening and positioning seats 543 approach each other, their straightening and positioning rollers 544 also approach each other. This close proximity of the rollers helps to straighten the workpiece, preventing it from tilting, and also clamps it in a centered position. Since the straightening and positioning rollers 544 can rotate relative to the straightening and positioning seats 543, the workpiece can move along the rollers, allowing it to be moved into the operating space 511 for correction operations.

[0071] In one embodiment of this application, such as Figure 1 , Figure 2 and Figure 4 As shown, the H-beam straightening device includes a straightening rotation drive assembly 550, which is mounted on the straightening mounting frame 510. The straightening rotation drive assembly 550 is connected to the straightening transmission component 524. The straightening rotation drive assembly 550 is used to drive the straightening transmission component 524 to rotate. The straightening transmission component 524 can rotate relative to the straightening seat 521 and can move up and down relative to the straightening mounting frame 510.

[0072] The workpiece is moved to the straightening transmission component 524 and comes into contact with it. Driven by the straightening rotation drive assembly 550, the straightening transmission component 524 rotates, allowing it to move the workpiece. Simultaneously, the straightening assembly 523 straightens the workpiece. When straightening workpieces of different sizes are required, the height adjustment assembly 522 moves the straightening seat 521 up and down to the appropriate position. As the straightening seat 521 moves, it causes the straightening assembly 523 and the straightening transmission component 524 to move up and down together, adjusting their positions. This ensures that the straightening assembly 523 can still straighten the workpiece, and the straightening transmission component 524 can still move the workpiece. Furthermore, since the straightening transmission component 524 can rotate relative to the straightening seat 521, it can remain in a rotating state when its height is adjusted. The system enables automatic adjustment of the height of the straightening component 523 and the straightening transmission component 524 to accommodate workpieces of different sizes without the need for a complicated disassembly and assembly process. Furthermore, the height can be adjusted while the straightening transmission component 524 is rotating, saving a significant amount of time and improving production efficiency.

[0073] Understandably, this application allows for height adjustment of the correction component 523 and the correction transmission component 524 without shutting down the correction rotation drive component 550, achieving non-stop adjustment, i.e., without having to shut down the correction transmission drive component before making height adjustments, thus saving time.

[0074] In one embodiment of this application, such as Figure 1 , Figure 2 and Figure 4 As shown, the straightening transmission component 524 includes a flat shaft 5241 and a drive roller 5242. The flat shaft 5241 passes through and is connected to the fixed bearing 5243. The fixed bearing 5243 is fixedly installed on the straightening seat 521. One end of the flat shaft 5241 is connected to the straightening rotation drive assembly 550, and the other end of the flat shaft 5241 is connected to the drive roller 5242.

[0075] It is understandable that the flat shaft 5241 and the straightening seat 521 are connected by the fixed bearing 5243, while the flat shaft 5241 can rotate relative to the fixed bearing 5243. In other words, the flat shaft 5241 can rotate relative to the straightening seat 521 and also move up and down together with the straightening seat 521, facilitating the adjustment of the height of the flat shaft 5241 and the drive roller 5242 connected to it. When moving the workpiece, the workpiece is moved to the drive roller 5242, and then the straightening rotation drive assembly 550 drives the flat shaft 5241 to rotate. The rotation of the flat shaft 5241 causes the drive roller 5242 to rotate along with it, and the rotation of the drive roller 5242 drives the workpiece to move, thus achieving automatic workpiece movement.

[0076] For example, the end of the flat shaft 5241 near the drive roller 5242 is a cylindrical structure, and the end of the flat shaft 5241 near the straightening rotation drive assembly 550 is a flat shaft structure.

[0077] In one embodiment of this application, such as Figure 1 , Figure 2 and Figure 4 As shown, the corrective rotation drive assembly 550 includes a corrective rotation drive 551 and a gear set 552. The corrective rotation drive 551 is connected to the gear set 552, and the gear set 552 is connected to the corrective transmission member 524. The corrective rotation drive 551 is used to drive the gear set 552 to rotate, so that the corrective transmission member 524 rotates.

[0078] It is understandable that the straightening rotation drive 551 drives the gear set 552 to rotate, and when the gear set 552 rotates, it will drive the straightening transmission 524 to rotate together, thereby realizing the automatic rotation of the straightening transmission 524, so that the straightening transmission 524 can drive the workpiece to move.

[0079] For example, the corrective rotation drive 551 is a motor.

[0080] In one embodiment of this application, such as Figure 5 , Figure 6 and Figure 7 As shown, the straightening assembly 523 includes a straightening roller 5231, a straightening frame 5232, and a straightening drive. The straightening roller 5231 is connected to the straightening frame 5232, and the straightening drive is connected to the straightening roller 5231. A straightening space is formed between the straightening roller 5231 and the straightening drive 524. The straightening drive is used to drive the straightening roller 5231 to move closer to or away from the straightening drive 524.

[0081] Understandably, a correction space is provided between the correction transmission component 524 and the correction roller 5231. First, the correction drive component moves the correction roller 5231 away from the correction transmission component 524, thus increasing the correction space to facilitate the movement of the workpiece into the correction space. When the workpiece is within the correction space, the correction drive component moves the correction roller 5231 closer to the correction transmission component 524, thus decreasing the correction space. This causes the correction roller 5231 and the correction transmission component 524 to clamp the workpiece. Once the workpiece is corrected to the correct position, the correction drive component stops moving the correction roller 5231, thereby achieving automatic correction of the workpiece.

[0082] For example, the corrective drive is a hydraulic cylinder or a pneumatic cylinder.

[0083] In one embodiment of this application, such as Figure 5 , Figure 6 and Figure 7 As shown, the corrective component 523 includes:

[0084] Two straightening rollers 5231, which are the first straightening roller and the second straightening roller, respectively;

[0085] The straightening connector 5233 is connected to the straightening frame 5232, and the first straightening roller and the second straightening roller are respectively connected to the two ends of the straightening connector 5233;

[0086] The connecting component 5234 is installed on the correction frame 5232. The connecting component 5234 is connected to the correction connecting seat 5233. The correction connecting seat 5233 can switch between a locked state and an unlocked state relative to the connecting component 5234. In the locked state, the correction connecting seat 5233 is fixedly connected to the connecting component 5234. In the unlocked state, the correction connecting seat 5233 can rotate relative to the connecting component 5234.

[0087] Understandably, to fix the straightening connector 5233 to the connecting assembly 5234, the workpiece is first straightened using one of the first and second straightening rollers. The straightening connector 5233 is then switched to the unlocked state, allowing it to rotate relative to the connecting assembly 5234. Rotating the straightening connector 5233 causes the first and second straightening rollers to rotate as well, thus switching their positions. Then, the straightening connector 5233 is switched to the locked state, fixing it to the connecting assembly 5234. At this point, the other of the first and second straightening rollers can be used to straighten different workpieces. Therefore, this application achieves the simultaneous presence of at least two different straightening rollers 5231, allowing switching between the first and second straightening rollers simply and conveniently, enabling the straightening of different workpieces.

[0088] It is understandable that since the first straightening roller and the second straightening roller have different diameters, the first straightening roller and the second straightening roller can straighten different workpieces respectively.

[0089] In one embodiment of this application, such as Figure 5 , Figure 6 and Figure 7 As shown, the connecting assembly 5234 includes a straightening connecting plate 5235 and a straightening connecting shaft 5236. The straightening connecting plate 5235 is mounted on the straightening frame 5232. One end of the straightening connecting shaft 5236 is connected to the straightening connecting plate 5235. The straightening connecting shaft 5236 is rotatably connected to the straightening connecting seat 5233. The straightening connecting plate 5235 is provided with a straightening mounting groove 5237. The straightening connecting seat 5233 is adapted to engage with the straightening mounting groove 5237.

[0090] Understandably, when the straightening connector 5233 is snapped into the straightening mounting groove 5237 of the straightening connector plate 5235, the straightening connector 5233 will be blocked by the groove wall of the straightening mounting groove 5237 and will not be able to rotate. At this time, the straightening connector 5233 is in a locked state, and the first straightening roller and the second straightening roller remain stable. At this time, one of the first straightening roller and the second straightening roller can be used to straighten the workpiece. An external force is applied to the straightening connector 5233, causing it to disengage from the straightening mounting groove 5237. At this time, the straightening connector 5233 is in an unlocked state. Since the straightening connecting shaft 5236 is rotatably connected to the straightening connector 5233, the straightening connector 5233 can rotate relative to the straightening connecting shaft 5236. The first straightening roller and the second straightening roller rotate accordingly, thereby achieving the position switching of the first straightening roller and the second straightening roller. Then, the straightening connector 5233 is snapped into the straightening mounting groove 5237, so that the straightening connector 5233 is locked again. At this time, the other of the first straightening roller and the second straightening roller can be used to straighten the workpiece.

[0091] For example, the straightening connecting plate 5235 has two opposing protrusions, and a straightening mounting groove 5237 is formed between the two protrusions. However, it should be understood that the straightening mounting groove 5237 can also be formed by any other suitable structure.

[0092] For example, the corrective connector 5233 has a protrusion that matches the corrective mounting slot 5237.

[0093] In one embodiment of this application, such as Figure 5 , Figure 6 and Figure 7 As shown, the connecting assembly 5234 includes a correction fixing baffle 5238, a correction connecting seat 5233 is provided with a rotating hole 5239 that matches the correction connecting shaft 5236, the other end of the correction connecting shaft 5236 passes through the rotating hole 5239, the correction fixing baffle 5238 abuts against the correction connecting seat 5233, and the correction fixing baffle 5238 is adapted to be detachably connected to the other end of the correction connecting shaft 5236.

[0094] Understandably, when the straightening connecting seat 5233 is snapped into the straightening mounting groove 5237, the straightening connecting seat 5233 will be limited by the straightening mounting groove 5237 and will not be able to rotate. At the same time, the other end of the straightening fixing baffle 5238 is connected to the straightening connecting shaft 5236. Since the straightening fixing baffle 5238 is also in contact with the straightening connecting seat 5233, the straightening fixing baffle 5238 can prevent the straightening connecting seat 5233 and the straightening connecting shaft 5236 from moving relative to each other. This prevents the straightening connecting seat 5233 from disengaging from the straightening mounting groove 5237, allowing the straightening connecting seat 5233 to remain stably locked. This can prevent the first straightening roller and the second straightening roller from moving when straightening the workpiece. When it is necessary to switch between the first and second straightening rollers, the straightening fixing baffle 5238 is removed from the other end of the straightening connecting shaft 5236, so that the straightening connecting seat 5233 can move relative to the straightening connecting shaft 5236. That is, by applying external force to the straightening connecting seat 5233, the straightening connecting seat 5233 can be disengaged from the straightening mounting groove 5237, so that the straightening connecting seat 5233 is in the unlocked state. Then, by rotating the straightening connecting seat 5233, the position switching of the first and second straightening rollers can be realized.

[0095] For example, the fixed baffle is detachably connected to the other end of the straightening connection shaft 5236 via a threaded connection.

[0096] According to an embodiment of the second aspect of this application, the steel structure production line includes the above-described H-beam straightening device.

[0097] The steel structure production line of this application embodiment realizes the simultaneous correction of both sides of the workpiece, and can realize the one-time correction of the workpiece without multiple correction devices, which simplifies the correction operation of the workpiece, saves a lot of time, and can also adjust the height and width of the correction device, so that the correction device can correct workpieces of different specifications and sizes.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
