Description

Technical Field

[0001] The present invention relates to the technical field of tension leveling equipment, and in particular to a tension leveling machine. Background Art

[0002] In steel casting, first, the dummy bar head and some transition pieces enter the mold to form a movable "inner bottom" of the mold. After pouring starts, the molten steel solidifies and condenses with the dummy bar head. The tension leveling machine pulls the dummy bar, continuously pulling the billet out of the mold until the dummy bar head separates from the billet behind the tension leveling machine. The tension leveling machine, also known as a stretch-bending straightening unit, is a mechanical device commonly used in the metal processing industry, mainly used for straightening and stretching metal sheets.

[0003] A Chinese patent with the publication number CN210755023U discloses a tension leveling machine with adjustable height of the pressure rollers, including a base, two top covers, two hydraulic cylinders, two lifting blocks, two first bearings, a driven pressure roller, two second bearings, a driving pressure roller, a gearbox, and a motor. The distance between the pressure rollers is adjustable, which can be applicable to billets of different diameters and improve the practicability.

[0004] Although the above technical solution solves the problem that in the prior art during the use of the tension leveling machine, it is difficult to adjust the height between the pressure rollers and the practicability is poor, it still has the problem of a single adjustment method. Although it can vertically adjust the distance between the pressure rollers to adapt to billets of different diameters, its adjustment range is restricted by the mechanical structure and cannot fully meet the processing requirements of billets of specific sizes, thus limiting the versatility and flexibility of the equipment. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the restriction of the adjustment range by the mechanical structure and be unable to fully meet the processing requirements of billets of specific sizes.

[0006] To solve the above technical problem, the present invention provides a tension leveling machine, including two support frame plates and a pressure roller adjustment component. Two upper pressure rollers are movably installed on the opposite sides of the two support frame plates, and two lower pressure rollers are movably installed on the opposite sides of the two support frame plates. The two upper pressure rollers are located above the two lower pressure rollers. The pressure roller adjustment component includes a hydraulic cylinder and a rotating seat. The pressure roller adjustment component vertically adjusts the positions of the two upper pressure rollers through the hydraulic cylinder, and vertically and horizontally adjusts the positions of the two upper pressure rollers simultaneously through the rotation of the rotating seat, and horizontally adjusts the positions of the two lower pressure rollers.

[0007] The vertical positions of the two upper pressure rollers passing through the hydraulic cylinder can be adjusted by the pressure roller adjusting assembly, so as to adjust the relative positions between the two upper pressure rollers and the two lower pressure rollers. Moreover, the positions of the two upper pressure rollers and the two lower pressure rollers can be adjusted simultaneously by the rotation of the rotating seat. It can not only achieve fine and flexible adjustment of the two upper pressure rollers and the two lower pressure rollers, but also adjust the number of straightening passes. This not only enhances the adaptability and flexibility of the straightening machine, but also significantly improves the accuracy and efficiency of the processing process. According to the specific characteristics of the billet and the straightening requirements, the positions of the two upper pressure rollers are finely adjusted to ensure the best contact pressure and distribution state between them and the two lower pressure rollers. By precisely controlling the relative positions between the pressure rollers, the billet can be more effectively guided to undergo plastic deformation during the stretching and bending processes, so as to achieve the expected straightening effect.

[0008] In an embodiment of the present invention, a movable pressure rod is fixedly installed at the output end of the hydraulic cylinder. Movable blocks I are fixedly installed at both ends of the movable pressure rod. Rotating columns are rotatably installed inside the movable blocks I. An installation folding plate is fixedly installed at one end of the rotating column. The two upper pressure rollers are rotatably installed on the opposite sides of the installation folding plate.

[0009] After the hydraulic cylinder is started, the output end of the hydraulic cylinder can push the movable pressure rod to move downward, thereby pushing the movable blocks I to move downward. The rotating columns drive the installation folding plate to move downward, thereby driving the two upper pressure rollers to move downward, adjusting the relative positions between the two upper pressure rollers and the two lower pressure rollers, which is suitable for straightening billets of different sizes, ensuring that the upper pressure rollers and the lower pressure rollers can evenly and stably apply pressure to the surface of the billet, avoiding uneven straightening or billet damage caused by uneven pressure. Moreover, the relative distances between the two upper pressure rollers and the two lower pressure rollers are the same, and the same billet can be straightened twice, ensuring that the billet can be uniformly and effectively stretched and bent throughout the straightening process, improving the straightening effect, and achieving efficient and precise straightening treatment.

[0010] In an embodiment of the present invention, a transmission wheel I is fixedly installed at one end of one of the rotating columns, and the rotating seat is fixedly installed at the end of the other rotating column. A transmission belt I is sleeved outside the transmission wheel I. A right-angle steering device is fixedly installed inside one of the support frame plates. A transmission wheel II is fixedly installed at the input end of the right-angle steering device. The end of the transmission belt I away from the transmission wheel I is sleeved outside the transmission wheel II. Threaded rods are fixedly installed at the output ends on both sides of the transmission wheel II. Movable blocks II are installed at both ends of the two lower pressure rollers through bearings, and the movable blocks II at one end of the two lower pressure rollers are threadedly connected to the outside of the threaded rods. Transmission wheels III are fixedly installed at one ends of the two lower pressure rollers. A transmission belt II is sleeved outside the transmission wheel III.

[0011] When straightening a billet that only needs to be straightened once, only the rotating seat needs to be rotated to prompt the rotating column to rotate, thereby driving the installation folding plate to rotate, driving the two upper pressure rollers to move in an arc, and when the installation folding plate rotates, it can drive the rotating column on the other side to rotate, thereby driving the first transmission wheel to rotate, and driving the second transmission wheel to rotate through the first transmission belt, and driving the two threaded rods to rotate after reversing through the right-angle steering device, so that the two second moving blocks move, and drive the two lower pressure rollers to move, so that one of the upper pressure rollers and one of the lower pressure rollers are in the same vertical plane and the vertical distance is close to each other, while the other upper pressure roller and the other lower pressure roller are staggered and the vertical distance is far from each other. The upper and lower pressure rollers in the same vertical plane can straighten the billet. One-time straightening and secondary straightening can be selected according to the properties of the billet, which can significantly improve the applicability of the production device and the overall production efficiency.

[0012] In an embodiment of the present invention, a fastening rotating ring is fixedly installed on the outer side of the rotating seat, a scale pointer is fixedly installed on the outer side of the rotating seat, an annular groove is opened on one side of one of the first moving blocks, the fastening rotating ring is rotatably installed inside the annular groove, an arc-shaped scale is fixedly installed on the outer side of the annular groove, the position of the scale pointer corresponds to the position of the arc-shaped scale, a fastening frame is fixedly installed on one side of one of the first moving blocks, one end of the fastening frame is threadedly connected with a fastening pressing bolt, a hand-turning handle is fixedly installed at one end of the fastening pressing bolt, and the fastening pressing bolt is located on one side of the fastening rotating ring.

[0013] When the rotating seat rotates, it can drive the fastening rotating ring to rotate inside the annular groove. When it rotates to the required position, the hand-turning handle can be rotated to drive the fastening pressing bolt to rotate. Finally, one end of the fastening pressing bolt abuts against one side of the fastening rotating ring, so as to fix the fastening rotating ring by the pressing force and friction force, thereby fixing the rotating seat, fixing the positions of the rotating column and the installation folding plate, and thus fixing the positions of the two upper pressure rollers, preventing the rotating column from rotating when straightening the billet, and ensuring the normal use of the device.

[0014] In an embodiment of the present invention, a downward moving push plate is fixedly installed on one side of one of the first moving blocks, T-shaped grooves are opened on both sides of the downward moving push plate, a sliding groove frame is fixedly installed on one side of one of the support frame plates, a sliding groove is opened inside the sliding groove frame, two belt sliding blocks are symmetrically and slidably installed inside the sliding groove, T-shaped blocks are fixedly installed on the opposite sides of the belt sliding blocks, the T-shaped blocks are slidably installed inside the T-shaped grooves, belt wheels are fixedly installed on one side of the belt sliding blocks, and the belt wheels are sleeved inside the first transmission belt.

[0015] When the first moving block moves downward, it can drive the downward moving push plate to move downward. When the downward moving push plate moves downward, it can make the T-shaped block move inside the T-shaped groove, and push the belt slider to move to both sides, making the belt pulley move to both sides, and expanding the first transmission belt to both sides, so that the first transmission belt is always in a taut state and sleeved outside the first driving wheel and the second driving wheel, ensuring that when the first driving wheel rotates, it can drive the second driving wheel to rotate through the first transmission belt, ensuring the normal use of the device, and thus ensuring that when the upper pressure roller moves in an arc shape, the two lower pressure rollers also move.

[0016] In an embodiment of the present invention, vertical moving grooves are respectively formed inside the two support frame plates, the first moving block is slidably installed inside the vertical moving grooves, horizontal moving grooves are respectively formed inside the two support frame plates, the second moving block is slidably installed inside the horizontal moving grooves, a slide bar is fixedly installed inside one of the horizontal moving grooves, and the second moving blocks at the ends of the two lower pressure rollers away from the threaded rod are slidably sleeved outside the slide bar.

[0017] The first moving block can move up and down inside the vertical moving groove. On the one hand, it ensures the stability of the first moving block during movement, and on the other hand, it ensures that the moving track of the first moving block remains vertical. The second moving block can move horizontally inside the horizontal moving groove and move outside the slide bar. On the one hand, it ensures the stability of the second moving block during movement, and on the other hand, it ensures that the moving track of the second moving block remains horizontal.

[0018] In an embodiment of the present invention, a top plate is fixedly installed on the tops of the two support frame plates, the hydraulic cylinder is fixedly installed on the top of the top plate, and a bottom plate is fixedly installed on the bottoms of the two support frame plates.

[0019] The top plate provided can support the hydraulic cylinder, provide a support force for the hydraulic cylinder, and ensure the normal use of the hydraulic cylinder. In addition, four support columns are provided at the bottom of the bottom plate. The bottom plate and the four support columns provided can support the device and ensure the normal operation of the device.

[0020] In an embodiment of the present invention, a rectangular groove is formed on the top of the bottom plate, a sliding support seat is slidably installed inside the rectangular groove, a motor mounting plate is fixedly installed on the top of the sliding support seat, a driving motor is fixedly installed on one side of the motor mounting plate, and the output end of the driving motor penetrates through the motor mounting plate and is fixedly connected to one end of one of the lower pressure rollers.

[0021] The driving motor can be supported and fixed by the provided sliding support base and motor mounting plate. After the driving motor is started, the output end of the driving motor can drive the pressing roller connected thereto to rotate, and drive another pressing roller to rotate through the provided transmission wheel three and transmission belt two, providing driving force for the billet straightening process, causing the billet placed on the top of the pressing roller to move and be straightened. When the second moving block moves inside the horizontal moving groove, the pressing roller can drive the driving motor to move, and drive the sliding support base to move inside the rectangular groove through the motor mounting plate, ensuring the normal operation of the device.

[0022] In an embodiment of the present invention, mounting sleeve plates are fixedly installed on one side of each of the two support frame plates. Mounting card slots are formed on the opposite sides of the mounting sleeve plates. Counters are installed inside the mounting card slots. Mounting card plates are fixedly installed on the outer sides of the counters. The specifications and dimensions of the mounting card plates are compatible with those of the mounting card slots. Adsorption magnets are symmetrically fixedly installed on one side of each of the mounting card plates.

[0023] The two provided counters can simultaneously detect the straightening length of the billet. On the one hand, the detected values of the two counters can be compared after the detection to ensure the accuracy of the detection. On the other hand, when one counter is damaged, the other counter can still detect in real time to ensure the detection and use effect of the device. The provided mounting card plates can be snap-fitted and installed inside the mounting card slots, and adsorbed and installed inside the mounting card slots through the adsorption magnets, facilitating the installation and replacement of the counters. They can be replaced during the operation of the equipment without the need to stop pouring and then process, ensuring stable production.

[0024] In an embodiment of the present invention, anti - rebound components are installed on one side of the support frame plate where the mounting sleeve plate is installed. The anti - rebound components are used to prevent the hydraulic cylinder from rebounding during the tension leveling process. The anti - rebound components include a mounting rod and an anti - rebound block. One end of the mounting rod is fixedly connected to one side of the support frame plate. The anti - rebound block is in a tapered shape, and in the initial state of the hydraulic cylinder, the tapered end of the anti - rebound block is located between the bottom of the top plate and the top of the moving pressure rod. A sleeve is fixedly installed at the end of the mounting rod away from the support frame plate. An inner rotating rod is movably installed inside the sleeve. Two rotating push rods are rotatably installed on the outer side of the inner rotating rod. A chute seat is fixedly installed at the top of the two rotating push rods. Moving slots are formed inside the two rotating push rods. One end of the anti - rebound block is fixedly installed with a connecting moving rod. The end of the connecting moving rod away from the anti - rebound block is slidably installed inside the chute seat. A moving sliding column is fixedly installed at the end of the connecting moving rod away from the anti - rebound block. The moving sliding column is slidably installed inside the moving slot. A limiting sliding seat is fixedly installed on the top of the anti - rebound block. A limiting chute is formed on the top of the top plate. The limiting sliding seat is slidably installed inside the limiting chute. A torsion spring is sleeved inside the sleeve. The torsion spring is sleeved on the outer side of the inner rotating rod. One end of the torsion spring is fixedly connected to the outer side of the inner rotating rod, and the other end of the torsion spring is fixedly connected to the inner side of the sleeve. In the initial state of the moving pressure rod, the torsion spring is in a twisted state.

[0025] By setting the anti - rebound components, the telescopic end of the hydraulic cylinder can be prevented from rebounding during the tension leveling process, ensuring high stability and accuracy of the hydraulic cylinder during operation. Furthermore, the relative position between the upper pressure roller and the lower pressure roller can be accurately and durably maintained stable. This not only avoids unnecessary twisting or deformation of the material during processing but also significantly improves the overall efficiency and finished product quality of the tension leveling operation. When the hydraulic cylinder starts to push the moving pressure rod downward, the gap between the moving pressure rod and the top plate increases. At this time, the torsion spring restores its deformation, causing the inner rotating rod to rotate inside the sleeve, thereby driving the rotating push rods to rotate counterclockwise. The top of the rotating push rods pulls one end of the connecting moving rod to move through the chute seat. During the movement, the connecting moving rod will move inside the chute seat, and the moving sliding column will move inside the moving slot, and pull the anti - rebound block to move towards the side close to the moving pressure rod, so that the anti - rebound block is inserted into the gap between the moving pressure rod and the top plate to play a role in supporting and preventing rebound. In addition, the torsion spring used is a high - strength steel wire torsion spring, which has a high elastic coefficient and tensile strength, can withstand a large torsional moment, and is not prone to plastic deformation.

[0026] The above - mentioned technical solution of the present invention has the following advantages compared with the prior art:

[0027] A tension leveller according to the present invention can adjust the vertical positions of two upper pressure rollers through a pressure roller adjustment assembly, thereby adjusting the relative positions between the two upper pressure rollers and the two lower pressure rollers. Moreover, the positions of the two upper pressure rollers and the two lower pressure rollers can be adjusted simultaneously by rotating a rotating seat. This not only enables fine and flexible adjustment of the two upper pressure rollers and the two lower pressure rollers, but also allows adjustment of the number of tension levelling operations. It not only enhances the adaptability and flexibility of the tension leveller, but also significantly improves the accuracy and efficiency of the processing process. According to the specific characteristics of the steel billet and the requirements of tension levelling, the positions of the two upper pressure rollers are finely adjusted to ensure the best contact pressure and distribution state between them and the two lower pressure rollers. By precisely controlling the relative positions between the pressure rollers, the plastic deformation of the steel billet during stretching and bending can be more effectively guided, thereby achieving the desired straightening effect.

[0028] A tension leveller according to the present invention rotates the rotating seat to cause the rotating column to rotate, thereby driving the mounting folding plate to rotate, and then driving the two upper pressure rollers to move in an arc. When the mounting folding plate rotates, it can drive the rotating column on the other side to rotate, thereby driving the first transmission wheel to rotate. And through the first transmission belt, it drives the second transmission wheel to rotate, and after reversing through a right-angle steering device, it drives two threaded rods to rotate, thereby moving two second moving blocks, and driving the two lower pressure rollers to move, so that one of the upper pressure rollers and one of the lower pressure rollers are in the same vertical plane and the vertical distance between them is close to each other, while the other upper pressure roller and the other lower pressure roller are staggered and the vertical distance between them is far from each other. The upper and lower pressure rollers in the same vertical plane can perform tension levelling on the steel billet. One-time tension levelling and two-time tension levelling can be selected according to the properties of the steel billet, which can significantly improve the applicability of the production device and the overall production efficiency.

[0041] The present invention will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the examples given are not intended to limit the present invention.

[0042] As Figures 1 to 10As shown in the figure, a tension leveling machine of the present invention includes two support frame plates 1 and a roll adjusting assembly. On the opposite sides of the two support frame plates 1, two upper pressure rolls 2 are movably installed, and on the opposite sides of the two support frame plates 1, two lower pressure rolls 3 are movably installed. The two upper pressure rolls 2 are located above the two lower pressure rolls 3. The roll adjusting assembly includes a hydraulic cylinder 4 and a rotating seat 17. The roll adjusting assembly vertically adjusts the positions of the two upper pressure rolls 2 through the hydraulic cylinder 4, and the roll adjusting assembly rotates through the rotating seat 17 to vertically and horizontally adjust the positions of the two upper pressure rolls 2 at the same time, and horizontally adjusts the positions of the two lower pressure rolls 3.

[0043] During operation, the vertical positions of the two upper pressure rolls 2 can be adjusted through the roll adjusting assembly by means of the hydraulic cylinder 4, so as to adjust the relative positions between the two upper pressure rolls 2 and the two lower pressure rolls 3. Moreover, the positions of the two upper pressure rolls 2 and the two lower pressure rolls 3 can be adjusted simultaneously by rotating the rotating seat 17. This can not only achieve fine and flexible adjustment of the two upper pressure rolls 2 and the two lower pressure rolls 3, but also adjust the number of tension leveling times. It not only enhances the adaptability and flexibility of the tension leveling machine, but also significantly improves the accuracy and efficiency of the processing process. According to the specific characteristics of the steel billet and the requirements of tension leveling, the positions of the two upper pressure rolls 2 are finely adjusted to ensure the best contact pressure and distribution state between them and the two lower pressure rolls 3. By precisely controlling the relative positions between the pressure rolls, the plastic deformation of the steel billet during the stretching and bending processes can be more effectively guided, so as to achieve the expected straightening effect.

[0044] As Figures 1 to 10 shown, in an embodiment of the present invention, a moving pressure rod 5 is fixedly installed at the output end of the hydraulic cylinder 4. Moving blocks 6 are fixedly installed at both ends of the moving pressure rod 5. Rotating columns 7 are rotatably installed inside the moving blocks 6. An installation folding plate 8 is fixedly installed at one end of the rotating column 7. The two upper pressure rolls 2 are rotatably installed on the opposite sides of the installation folding plate 8.

[0045] During operation, after the hydraulic cylinder 4 is started, the output end of the hydraulic cylinder 4 can push the moving pressure rod 5 downward, thereby pushing the moving blocks 6 downward. The installation folding plate 8 is driven to move downward through the rotating columns 7, thereby driving the two upper pressure rolls 2 to move downward, adjusting the relative positions between the two upper pressure rolls 2 and the two lower pressure rolls 3, which is suitable for tension leveling of steel billets of different sizes, ensuring that the upper pressure rolls 2 and the lower pressure rolls 3 can evenly and stably apply pressure to the surface of the steel billet, avoiding uneven tension leveling or damage to the steel billet caused by uneven pressure. Moreover, the relative distances between the two upper pressure rolls 2 and the two lower pressure rolls 3 are the same, and the same steel billet can be subjected to secondary tension leveling, ensuring that the steel billet can be uniformly and effectively stretched and bent throughout the tension leveling process, improving the tension leveling effect, and achieving efficient and precise tension leveling processing.

[0046] As Figures 1 to 10As shown, in an embodiment of the present invention, a first transmission wheel 9 is fixedly installed at one end of one of the rotating columns 7, and the rotating seat 17 is fixedly installed at one end of the other rotating column 7. A first transmission belt 10 is sleeved outside the first transmission wheel 9. A right-angle steering device 11 is fixedly installed inside one of the support frame plates 1. A second transmission wheel 12 is fixedly installed at the input end of the right-angle steering device 11. The end of the first transmission belt 10 away from the first transmission wheel 9 is sleeved outside the second transmission wheel 12. Threaded rods 13 are fixedly installed at the output ends on both sides of the second transmission wheel 12. Moving blocks two 14 are installed at both ends of the two lower pressing rollers 3 through bearings, and the moving blocks two 14 at one end of the two lower pressing rollers 3 are threadedly connected to the outside of the threaded rods 13. A third transmission wheel 15 is fixedly installed at one end of each of the two lower pressing rollers 3. A second transmission belt 16 is sleeved outside the third transmission wheel 15.

[0047] During operation, when straightening a billet that only needs to be straightened once, only need to rotate the rotating seat 17 counterclockwise, prompting the rotating column 7 to rotate counterclockwise, thereby driving the installation folding plate 8 to rotate counterclockwise, thereby driving the two upper pressing rollers 2 to rotate counterclockwise by a certain angle. And when the installation folding plate 8 rotates, it can drive the rotating column 7 on the other side to rotate counterclockwise, thereby driving the first transmission wheel 9 to rotate counterclockwise, and driving the second transmission wheel 12 to rotate counterclockwise through the first transmission belt 10, and driving the two threaded rods 13 to rotate after reversing through the right-angle steering device 11, so that the two moving blocks two 14 move in the same direction, and drive the two lower pressing rollers 3 to move in the same direction. And during the process of the rotating column 7 rotating counterclockwise by 90 degrees, the horizontal moving distance of one of the upper pressing rollers 2 and the horizontal moving distance of one of the lower pressing rollers 3 are the same, and the horizontal moving speed is the same, so as to ensure that one of the upper pressing rollers 2 and one of the lower pressing rollers 3 are in the same vertical plane and the vertical distance is close to each other, while the other upper pressing roller 2 and the other lower pressing roller 3 are staggered and the vertical distance is far from each other. The upper pressing roller 2 and the lower pressing roller 3 in the same vertical plane can straighten the billet. One-time straightening and secondary straightening can be selected according to the properties of the billet, which can significantly improve the applicability of the production device and the overall production efficiency.

[0048] As Figures 1 to 10As shown, in an embodiment of the present invention, a fastening rotating ring 18 is fixedly installed on the outer side of the rotating seat 17, and a scale pointer 19 is fixedly installed on the outer side of the rotating seat 17. An annular groove 20 is formed on one side of one of the first moving blocks 6. The fastening rotating ring 18 is rotatably installed inside the annular groove 20. An arc-shaped scale 21 is fixedly installed on the outer side of the annular groove 20. The position of the scale pointer 19 corresponds to the position of the arc-shaped scale 21. A fastening frame 22 is fixedly installed on one side of one of the first moving blocks 6. One end of the fastening frame 22 is threadedly connected with a fastening pressing bolt 23. A hand-rotating handle 24 is fixedly installed at one end of the fastening pressing bolt 23. The fastening pressing bolt 23 is located on one side of the fastening rotating ring 18.

[0049] During operation, when the rotating seat 17 rotates, it can drive the fastening rotating ring 18 to rotate inside the annular groove 20. When it rotates to the required position, the hand-rotating handle 24 can be rotated to drive the fastening pressing bolt 23 to rotate. Finally, one end of the fastening pressing bolt 23 abuts against one side of the fastening rotating ring 18, so as to fix the fastening rotating ring 18 by the pressing force and friction force, thereby fixing the rotating seat 17, fixing the positions of the rotating column 7 and the mounting folding plate 8, and thus fixing the positions of the two upper pressure rollers 2, preventing the rotating column 7 from rotating when straightening the steel billet, and ensuring the normal use of the device.

[0050] As Figures 1 to 10 As shown, in an embodiment of the present invention, a downward moving push plate 25 is fixedly installed on one side of one of the first moving blocks 6. T-shaped grooves 26 are formed on both sides of the downward moving push plate 25. A sliding groove frame 27 is fixedly installed on one side of one of the support frame plates 1. A sliding groove 28 is formed inside the sliding groove frame 27. Two belt slider blocks 29 are symmetrically and slidably installed inside the sliding groove 28. T-shaped blocks 30 are fixedly installed on the opposite sides of the belt slider blocks 29. The T-shaped blocks 30 are slidably installed inside the T-shaped grooves 26. Belt wheels 31 are fixedly installed on one side of each of the belt slider blocks 29. The belt wheels 31 are sleeved inside the first transmission belt 10.

[0051] During operation, when the first moving block 6 moves downward, it can drive the downward moving push plate 25 to move downward. When the downward moving push plate 25 moves downward, the T-shaped blocks 30 can move inside the T-shaped grooves 26, and push the belt slider blocks 29 to move to both sides, causing the belt wheels 31 to move to both sides, and expanding the first transmission belt 10 to both sides, so that the first transmission belt 10 is always in a taut state and sleeved outside the first transmission wheel 9 and the second transmission wheel 12, ensuring that when the first transmission wheel 9 rotates, it can drive the second transmission wheel 12 to rotate through the first transmission belt 10, ensuring the normal use of the device, and thus ensuring that when the upper pressure roller 2 moves in an arc shape, the two lower pressure rollers 3 also move.

[0052] As Figures 1 to 10As shown, in an embodiment of the present invention, vertical moving grooves 32 are formed inside both of the two support frame plates 1. The first moving block 6 is slidably installed inside the vertical moving groove 32. Horizontal moving grooves 33 are formed inside both of the two support frame plates 1. The second moving block 14 is slidably installed inside the horizontal moving groove 33. A slide bar 34 is fixedly installed inside one of the horizontal moving grooves 33. The second moving blocks 14 at the ends of the two pressing rollers 3 away from the threaded rod 13 are slidably sleeved outside the slide bar 34.

[0059] During operation, the two provided counters 43 can simultaneously detect the straightening length of the billet. On the one hand, the detected values of the two counters 43 can be compared after the detection to ensure the accuracy of the detection. On the other hand, when one counter 43 is damaged, the other counter 43 can still perform real-time detection to ensure the detection and use effect of the device. The provided mounting card plates 44 can be snap-fitted and installed inside the mounting card slots 42, and adsorbed and installed inside the mounting card slots 42 through the adsorption magnets 45, facilitating the installation and replacement of the counters 43. They can be replaced during the operation of the equipment without the need to stop casting and then process, ensuring stable production.

[0060] As Figures 1 to 10As shown, in an embodiment of the present invention, anti - rebound components are installed on one side of the support frame plate 1 where the mounting sleeve plate 41 is installed. The anti - rebound components are used to prevent the hydraulic cylinder 4 from rebounding during the tension leveling process. The anti - rebound components include a mounting rod 46 and an anti - rebound block 47. One end of the mounting rod 46 is fixedly connected to one side of the support frame plate 1. The anti - rebound block 47 is conical, and in the initial state of the hydraulic cylinder 4, the conical end of the anti - rebound block 47 is located between the bottom of the top plate 35 and the top of the moving pressure rod 5. The end of the mounting rod 46 away from the support frame plate 1 is fixedly installed with an outer sleeve 48. An inner rotating rod 49 is movably installed inside the outer sleeve 48. Two rotating push rods 51 are rotatably installed on the outer side of the inner rotating rod 49. A chute seat 52 is fixedly installed at the top of the two rotating push rods 51. Moving slots 53 are opened inside the two rotating push rods 51. One end of the anti - rebound block 47 is fixedly installed with a connecting moving rod 54. The end of the connecting moving rod 54 away from the anti - rebound block 47 is slidably installed inside the chute seat 52. The end of the connecting moving rod 54 away from the anti - rebound block 47 is fixedly installed with a moving sliding column 55. The moving sliding column 55 is slidably installed inside the moving slot 53. A limiting sliding seat 56 is fixedly installed on the top of the anti - rebound block 47. A limiting chute 57 is opened on the top of the top plate 35. The limiting sliding seat 56 is slidably installed inside the limiting chute 57. A torsion spring 50 is sleeved inside the outer sleeve 48. The torsion spring 50 is sleeved on the outer side of the inner rotating rod 49. One end of the torsion spring 50 is fixedly connected to the outer side of the inner rotating rod 49, and the other end of the torsion spring 50 is fixedly connected to the inner side of the outer sleeve 48. In the initial state of the moving pressure rod 5, the torsion spring 50 is in a twisted state.

[0061] During operation, the anti - rebound components provided can prevent the telescopic end of the hydraulic cylinder 4 from rebounding during the tension leveling process, ensuring the high stability and precision of the height of the hydraulic cylinder 4 during operation. Furthermore, the relative position between the upper pressure roller 2 and the lower pressure roller 3 can be accurately and durably maintained stable. This not only avoids unnecessary twisting or deformation of the material during processing but also significantly improves the overall efficiency and finished product quality of the tension leveling operation. When the hydraulic cylinder 4 is started to push the moving pressure rod 5 downward, the gap between the moving pressure rod 5 and the top plate 35 increases. At this time, the torsion spring 50 restores its deformation, causing the inner rotating rod 49 to rotate inside the outer sleeve 48, thereby driving the rotating push rod 51 to rotate counterclockwise. The top of the rotating push rod 51 pulls one end of the connecting moving rod 54 to move through the chute seat 52. During the movement, the connecting moving rod 54 will move inside the chute seat 52, and the moving sliding column 55 will move inside the moving slot 53, and pull the anti - rebound block 47 to move towards the side close to the moving pressure rod 5, so that the anti - rebound block 47 is inserted into the gap between the moving pressure rod 5 and the top plate 35 to play a role in supporting and preventing rebound. In addition, the torsion spring 50 is a high - strength steel wire torsion spring, which has a high elastic coefficient and tensile strength, can withstand a large torsional moment, and is not prone to plastic deformation.

[0062] Working principle: The vertical positions of the two upper pressure rollers 2 passing through the hydraulic cylinder 4 can be adjusted through the pressure roller adjusting assembly, so as to adjust the relative positions between the two upper pressure rollers 2 and the two lower pressure rollers 3. Moreover, the positions of the two upper pressure rollers 2 and the two lower pressure rollers 3 can be adjusted simultaneously by rotating the rotating seat 17. This can not only achieve fine and flexible adjustment of the two upper pressure rollers 2 and the two lower pressure rollers 3, but also adjust the number of tension leveling times. It not only enhances the adaptability and flexibility of the tension leveling machine, but also significantly improves the accuracy and efficiency of the processing process. According to the specific characteristics of the steel billet and the tension leveling requirements, the positions of the two upper pressure rollers 2 are finely adjusted to ensure the best contact pressure and distribution state between them and the two lower pressure rollers 3. By precisely controlling the relative positions between the pressure rollers, the plastic deformation of the steel billet during the stretching and bending processes can be more effectively guided, so as to achieve the expected straightening effect.

[0063] After the hydraulic cylinder 4 is started, the output end of the hydraulic cylinder 4 can push the movable pressure rod 5 downward, thereby pushing the first movable block 6 downward. The rotating column 7 drives the mounting folding plate 8 downward, thereby driving the two upper pressure rollers 2 downward to adjust the relative positions between the two upper pressure rollers 2 and the two lower pressure rollers 3, which is applicable to tension leveling of steel billets of different sizes. It ensures that the upper pressure rollers 2 and the lower pressure rollers 3 can apply pressure evenly and stably to the surface of the steel billet, avoiding uneven tension leveling or damage to the steel billet caused by uneven pressure. Moreover, the relative distances between the two upper pressure rollers 2 and the two lower pressure rollers 3 are the same, and the same steel billet can be subjected to secondary tension leveling to ensure that the steel billet can be uniformly and effectively stretched and bent throughout the tension leveling process, improving the tension leveling effect and achieving efficient and precise tension leveling processing.

[0064] When straightening a billet that only needs to be straightened once, only need to rotate the rotating seat 17 counterclockwise, prompting the rotating column 7 to rotate counterclockwise, thereby driving the mounting folding plate 8 to rotate counterclockwise, thereby driving the two upper pressure rollers 2 to rotate counterclockwise by a certain angle. And when the mounting folding plate 8 rotates, it can drive the rotating column 7 on the other side to rotate counterclockwise, thereby driving the first transmission wheel 9 to rotate counterclockwise, and driving the second transmission wheel 12 to rotate counterclockwise through the first transmission belt 10, and driving the two threaded rods 13 to rotate after reversing through the right-angle steering device 11, so that the two second moving blocks 14 move in the same direction, and drive the two lower pressure rollers 3 to move in the same direction. And during the process of the rotating column 7 rotating counterclockwise by 90 degrees, the horizontal moving distance of one of the upper pressure rollers 2 and the horizontal moving distance of one of the lower pressure rollers 3 are the same, and the horizontal moving speeds are the same, so as to ensure that one of the upper pressure rollers 2 and one of the lower pressure rollers 3 are in the same vertical plane, and the vertical distance is close to each other, while the other upper pressure roller 2 and the other lower pressure roller 3 are staggered from each other, and the vertical distance is far from each other. The upper pressure roller 2 and the lower pressure roller 3 in the same vertical plane can straighten the billet. It is possible to select single straightening and double straightening according to the properties of the billet, which can significantly improve the applicability of the production device and the overall production efficiency.

[0065] When the rotating seat 17 rotates, it can drive the fastening rotating ring 18 to rotate inside the annular groove 20. When it rotates to the required position, the hand-operated handle 24 can be rotated to drive the fastening pressing bolt 23 to rotate. Finally, one end of the fastening pressing bolt 23 abuts against one side of the fastening rotating ring 18, so as to fix the fastening rotating ring 18 by the pressing force and friction force, thereby fixing the rotating seat 17, fixing the positions of the rotating column 7 and the mounting folding plate 8, and thus fixing the positions of the two upper pressure rollers 2, preventing the rotating column 7 from rotating when straightening the billet, and ensuring the normal use of the device.

[0066] When the first moving block 6 moves downward, it can drive the downward moving push plate 25 to move downward. When the downward moving push plate 25 moves downward, it can make the T-shaped block 30 move inside the T-shaped groove 26, and push the belt slider 29 to move to both sides, making the belt pulley 31 move to both sides, and expanding the first transmission belt 10 to both sides, so that the first transmission belt 10 is always tightly sleeved outside the first transmission wheel 9 and the second transmission wheel 12, ensuring that when the first transmission wheel 9 rotates, it can drive the second transmission wheel 12 to rotate through the first transmission belt 10, ensuring the normal use of the device, and thus ensuring that when the upper pressure roller 2 moves in an arc, the two lower pressure rollers 3 also move.

[0067] The first moving block 6 can move up and down inside the vertical moving groove 32. On the one hand, it ensures the stability of the first moving block 6 during movement. On the other hand, it ensures that the movement track of the first moving block 6 remains vertical. The second moving block 14 can move horizontally inside the horizontal moving groove 33 and move outside the sliding rod 34. On the one hand, it ensures the stability of the second moving block 14 during movement. On the other hand, it ensures that the movement track of the second moving block 14 remains horizontal.

[0068] The top plate 35 provided can support the hydraulic cylinder 4, provide a supporting force for the hydraulic cylinder 4, and ensure the normal use of the hydraulic cylinder 4. In addition, four support columns are provided at the bottom of the bottom plate 36. The device can be supported by the provided bottom plate 36 and the four support columns to ensure the normal operation of the device.

[0069] The driving motor 40 can be supported and fixed by the provided sliding support base 38 and the motor mounting plate 39. After the driving motor 40 is started, the output end of the driving motor 40 can drive the lower pressing roller 3 connected to it to rotate, and drive another lower pressing roller 3 to rotate through the provided third transmission wheel 15 and the second transmission belt 16, providing a driving force for the billet straightening process, enabling the billet placed on the top of the lower pressing roller 3 to move and be straightened. When the second moving block 14 moves inside the horizontal moving groove 33, the lower pressing roller 3 can drive the driving motor 40 to move, and drive the sliding support base 38 to move inside the rectangular groove 37 through the motor mounting plate 39 to ensure the normal operation of the device.

[0070] The two counters 43 provided can simultaneously detect the straightening length of the billet. On the one hand, the detected values of the two counters 43 can be compared after the detection to ensure the accuracy of the detection. On the other hand, when one counter 43 is damaged, the other counter 43 can also detect in real time to ensure the detection use effect of the device. The mounting card plate 44 provided can be clamped and installed inside the mounting card slot 42 and adsorbed and installed inside the mounting card slot 42 through the adsorption magnet 45, facilitating the installation and replacement of the counter 43. It can be replaced during the operation of the equipment without the need to stop pouring and then process, ensuring stable production.

[0071] The anti-rebound component can prevent the telescopic end of the hydraulic cylinder 4 from rebounding during the tension leveling process, ensuring high stability and precision of the hydraulic cylinder 4 during operation. As a result, the relative position between the upper pressure roller 2 and the lower pressure roller 3 can be accurately and durably maintained stable. This not only avoids unnecessary twisting or deformation of the material during processing but also significantly improves the overall efficiency and finished product quality of the tension leveling operation. When the hydraulic cylinder 4 starts to push the moving pressure rod 5 downward, the gap between the moving pressure rod 5 and the top plate 35 increases. At this time, the torsion spring 50 resumes deformation, causing the inner rotating rod 49 to rotate inside the outer sleeve 48, thereby driving the rotating push rod 51 to rotate counterclockwise. The top of the rotating push rod 51 pulls one end of the connecting moving rod 54 through the chute seat 52 to move. During the movement, the connecting moving rod 54 will move inside the chute seat 52, and the moving slide column 55 will move inside the moving notch 53, and pull the anti-rebound block 47 to move toward the side close to the moving pressure rod 5, so that the anti-rebound block 47 is inserted into the gap between the moving pressure rod 5 and the top plate 35 to play a role in supporting anti-rebound. In addition, the torsion spring 50 is a high-strength steel wire torsion spring with a high elastic coefficient and tensile strength, which can withstand a large torsional moment and is not prone to plastic deformation.

[0072] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
