Description

Technical Field

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

[0002] In steel casting, the starter head and some transition pieces are first placed into the crystallizer to form a movable "inner bottom" of the crystallizer. After pouring begins, the molten steel solidifies and condenses together with the starter head. The starter rod is pulled by the straightening machine to continuously pull the ingot out of the crystallizer until the starter head passes through the rear of the straightening machine and is separated from the ingot. The straightening machine, also known as the stretching, bending and straightening unit, is a mechanical equipment commonly used in the metal processing industry, mainly used for straightening and stretching metal sheets.

[0003] A Chinese patent with announcement number CN210755023U discloses a tension straightening machine with adjustable pressure roller height, including a base, two sets of top covers, two sets of hydraulic cylinders, two sets of lifting blocks, two sets of first bearings, driven pressure rollers, two sets of second bearings, active pressure rollers, a gearbox and a motor. The distance between the pressure rollers is adjustable, which can be suitable for castings of different diameters, thereby improving practicality.

[0004] Although the above technical solution solves the problem that the height between the pressure rollers is difficult to adjust and the practicality is poor during the use of the tensioning and straightening machine in the existing technology, it still has the problem of a single adjustment method. Although the pressure roller spacing can be adjusted vertically to accommodate castings of different diameters, its adjustment range is restricted by the mechanical structure and cannot fully meet the processing requirements of castings of specific sizes, thereby 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 the inability to fully meet the processing requirements of the casting blank of a specific size.

[0006] In order to solve the above technical problems, the present invention provides a straightening machine, including two supporting frame plates and a pressure roller adjustment assembly, two upper pressure rollers are movably installed on the opposite sides of the two supporting frame plates, and two lower pressure rollers are movably installed on the opposite sides of the two supporting frame plates, the two upper pressure rollers are located above the two lower pressure rollers, and the pressure roller adjustment assembly includes a hydraulic cylinder and a rotating seat. The pressure roller adjustment assembly vertically adjusts the positions of the two upper pressure rollers through the hydraulic cylinder, and the pressure roller adjustment assembly simultaneously adjusts the positions of the two upper pressure rollers vertically and laterally by rotating the rotating seat, and adjusts the positions of the two lower pressure rollers laterally.

[0007] The roller adjustment assembly can be used to adjust the vertical position of the two upper rollers through the hydraulic cylinder, thereby adjusting the relative position between the two upper rollers and the two lower rollers, and the positions of the two upper rollers and the two lower rollers can also be adjusted simultaneously by rotating the rotating seat, which not only can achieve fine and flexible adjustment of the two upper rollers and the two lower rollers, but also can achieve adjustment of the number of straightening times, which 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 rollers are fine-tuned to ensure that they form the best contact pressure and distribution state with the two lower rollers. By accurately controlling the relative position between the rollers, the billet can be more effectively guided to undergo plastic deformation during stretching and bending, thereby achieving the expected straightening effect.

It is suitable for straightening steel billets of different sizes, ensuring that the upper pressure rollers and the lower pressure rollers can apply pressure to the surface of the steel billet evenly and stably, avoiding uneven straightening or damage to the steel billet due to uneven pressure, and the relative distance between the two upper pressure rollers and the two lower pressure rollers is the same, so the same steel billet can be straightened for a second time, ensuring that the steel billet can be subjected to uniform and effective stretching and bending during the entire straightening process, thereby improving the straightening effect and achieving efficient and precise straightening processing.

In addition, four supporting columns are arranged at the bottom of the bottom plate 36.

[0058] like Figures 1 to 10 As shown, in one embodiment of the present invention, a mounting sleeve 41 is fixedly installed on one side of the two supporting frame plates 1, and mounting slots 42 are opened on opposite sides of the mounting sleeve plates 41.

The specifications and dimensions of the mounting cards 44 are consistent with the specifications and dimensions of the mounting slots 42, and adsorption magnets 45 are symmetrically fixedly installed on one side of the mounting cards 44.

[0059] During operation, the two counters 43 can be used to detect the straightening length of the steel billet at the same time. On the one hand, the detection 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 be used for real-time detection to ensure the detection effect of the device. The installation card plate 44 can be installed on the inner side of the installation slot 42, and can be installed on the inner side of the installation slot 42 by adsorption magnet 45, which is convenient for installation and replacement of the counter 43. It can be replaced while the equipment is running without stopping the casting and reprocessing, thereby ensuring stable production.

[0060] like Figures 1 to 10As shown, in one embodiment of the present invention, an anti-rebound component is installed on one side of the support frame plate 1 on which the mounting sleeve plate 41 is installed. The anti-rebound component is used to prevent the hydraulic cylinder 4 from rebounding during the straightening process. The anti-rebound component includes 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 in a pointed cone shape, and the pointed cone end of the anti-rebound block 47 is located between the bottom of the top plate 35 and the top of the movable pressure rod 5 in the initial state of the hydraulic cylinder 4. An outer sleeve 48 is fixedly installed on the end of the mounting rod 46 away from the support frame plate 1, and 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 slide slot seat 52 is fixedly installed on the top of the two rotating push rods 51, and movable slots are provided inside the two rotating push rods 51. 53, a connecting moving rod 54 is fixedly installed at one end of the anti-rebound block 47, and the end of the connecting moving rod 54 away from the anti-rebound block 47 is slidably installed on the inner side of the slide slot seat 52, and a moving slide column 55 is fixedly installed at the end of the connecting moving rod 54 away from the anti-rebound block 47, and the moving slide column 55 is slidably installed on the inner side of the moving slot 53, and a limiting slide seat 56 is fixedly installed on the top of the anti-rebound block 47. A limiting slide slot 57 is provided on the top of the top plate 35, and the limiting slide seat 56 is slidably installed on the inner side of the limiting slide slot 57. A torsion spring 50 is sleeved on the inner side of the outer sleeve 48, and 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 movable pressure rod 5, the torsion spring 50 is in a twisted state.

[0061] During operation, the anti-rebound component can prevent the telescopic end of the hydraulic cylinder 4 from rebounding during the straightening process, ensuring that the hydraulic cylinder 4 maintains a high degree of stability and accuracy during operation, thereby allowing the relative position between the upper pressure roller 2 and the lower pressure roller 3 to be accurately and permanently maintained stable, which not only avoids unnecessary distortion or deformation of the material during processing, but also significantly improves the overall efficiency of the straightening operation and the quality of the finished product. When the hydraulic cylinder 4 starts to push the movable pressure rod 5 downward, the gap between the movable pressure rod 5 and the top plate 35 increases, and at this time the torsion spring 50 recovers its deformation, causing the inner rotating rod 49 to rotate inside the outer sleeve 48, thereby driving the rotating The push rod 51 rotates counterclockwise, so that the top of the rotating push rod 51 pulls one end of the connected moving rod 54 to move through the slide groove seat 52, and during the movement, the connected moving rod 54 will move inside the slide groove seat 52, and the moving slide column 55 will move inside the moving groove 53, and pull the anti-rebound block 47 to move to 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, playing a supporting and anti-rebound role. 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 torque and is not prone to plastic deformation.

[0062] Working principle: The vertical position of the two upper pressure rollers 2 can be adjusted by the pressure roller adjustment assembly through the hydraulic cylinder 4, so as to adjust the relative position between the two upper pressure rollers 2 and the two lower pressure rollers 3, and the positions of the two upper pressure rollers 2 and the two lower pressure rollers 3 can also be adjusted at the same time by rotating the rotating seat 17, which not only can realize the fine and flexible adjustment of the two upper pressure rollers 2 and the two lower pressure rollers 3, but also can realize the adjustment of the number of straightening times, which 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 steel billet and the straightening requirements, the positions of the two upper pressure rollers 2 are fine-tuned to ensure that they form the best contact pressure and distribution state with the two lower pressure rollers 3. By accurately controlling the relative position between the pressure rollers, the steel billet can be more effectively guided to undergo plastic deformation during the stretching and bending process, thereby achieving the expected straightening effect.

[0063] After being started by the hydraulic cylinder 4, the output end of the hydraulic cylinder 4 can push the moving pressure rod 5 to move downward, thereby pushing the moving block 6 to move downward, and driving the mounting folding plate 8 to move downward through the rotating column 7, thereby driving the two upper pressure rollers 2 to move downward, and adjusting the relative positions of the two upper pressure rollers 2 and the two lower pressure rollers 3, which is suitable for straightening steel billets of different sizes, ensuring that the upper pressure rollers 2 and the lower pressure rollers 3 can apply pressure to the surface of the steel billet evenly and stably, avoiding uneven straightening or damage to the steel billet due to uneven pressure, and the relative distance between the two upper pressure rollers 2 and the two lower pressure rollers 3 is the same, so the same steel billet can be straightened for the second time, ensuring that the steel billet can be subjected to uniform and effective stretching and bending during the entire straightening process, thereby improving the straightening effect and achieving efficient and precise straightening processing.

[0064] When straightening a steel billet that only needs to be straightened once, it is only necessary to rotate the rotating seat 17 counterclockwise to cause the rotating column 7 to rotate counterclockwise, thereby driving the installation folding plate 8 to rotate counterclockwise, thereby driving the two upper pressure rollers 2 to rotate counterclockwise at 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 transmission wheel 1 9 to rotate counterclockwise, and drive the transmission wheel 2 12 to rotate counterclockwise through the transmission belt 1 10, and drive the two threaded rods 13 to rotate after reversing through the right-angle steering device 11, so that the two moving blocks 2 14 move in the same direction, and drive the two lower pressure rollers 3 They move in the same direction, and in the process of the rotating column 7 rotating 90 degrees counterclockwise, the lateral movement distance of one of the upper pressure rollers 2 and the lateral movement distance of one of the lower pressure rollers 3 are the same, and the lateral movement speed is the same, thereby ensuring that one of the upper pressure rollers 2 and one of the lower pressure rollers 3 remain 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 with each other, and the vertical distance is far away from each other. The steel billet can be stretched and straightened by the upper pressure roller 2 and the lower pressure roller 3 in the same vertical plane, and the primary stretching and secondary stretching and straightening can be selected according to the properties of the steel billet, which can significantly improve the applicability of the production equipment and the overall production efficiency.

[0065] When the rotating seat 17 rotates, the fastening swivel 18 can be driven to rotate inside the annular groove 20. When it rotates to the required position, the hand handle 24 can be turned to drive the fastening pressure bolt 23 to rotate, and finally one end of the fastening pressure bolt 23 is abutted against one side of the fastening swivel 18, so that the fastening swivel 18 is fixed by pressing force and friction force, thereby fixing the rotating seat 17, fixing the position of the rotating column 7 and the mounting folding plate 8, and fixing the position of the two upper pressure rollers 2, thereby preventing the rotating column 7 from rotating when the steel billet is straightened, and ensuring the normal use of the device.

[0066] When the moving block 6 moves downward, it can drive the downward push plate 25 to move downward. When the downward push plate 25 moves downward, the T-block 30 can move on the inner side of the T-slot 26, and push the belt slider 29 to move to both sides, so that the belt wheel 31 moves to both sides, and the transmission belt 10 expands to both sides, so that the transmission belt 10 is always in a taut state and is sleeved on the outside of the transmission wheel 1 9 and the transmission wheel 2 12, ensuring that when the transmission wheel 9 rotates, the transmission belt 10 can drive the transmission wheel 2 12 to rotate, ensuring the normal use of the device, thereby ensuring that when the upper pressure roller 2 moves in an arc shape, the two lower pressure rollers 3 also move.

[0067] The moving block 1 6 can move up and down inside the vertical moving groove 32, which on the one hand ensures the stability of the moving block 1 6 when moving, and on the other hand ensures that the moving trajectory of the moving block 1 6 remains vertical. The moving block 2 14 can move laterally inside the transverse moving groove 33 and move on the outside of the sliding rod 34, which on the one hand ensures the stability of the moving block 2 14 when moving, and on the other hand ensures that the moving trajectory of the moving block 2 14 remains horizontal.

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

[0069] The driving motor 40 can be supported and fixed by the provided sliding support seat 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 pressure roller 3 connected thereto to rotate, and drive the other lower pressure roller 3 to rotate through the provided transmission wheel three 15 and transmission belt two 16, thereby providing driving force for the billet straightening process, so that the billet placed on the top of the lower pressure roller 3 can be moved and straightened, and when the moving block two 14 moves inside the transverse moving groove 33, the lower pressure roller 3 can drive the driving motor 40 to move, and drive the sliding support seat 38 to move inside the rectangular groove 37 through the motor mounting plate 39, thereby ensuring the normal operation of the device.

[0070] The two counters 43 can be used to detect the straightening length of the steel billet at the same time. On the one hand, the detection 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 be used for real-time detection to ensure the detection effect of the device. The installation card plate 44 can be installed on the inner side of the installation slot 42 and can be installed on the inner side of the installation slot 42 by adsorption magnet 45, which is convenient for installation and replacement of the counter 43. It can be replaced while the equipment is running without stopping the casting and processing, thereby ensuring stable production.

[0071] The anti-rebound component can prevent the telescopic end of the hydraulic cylinder 4 from rebounding during the straightening process, ensuring that the hydraulic cylinder 4 maintains a high degree of stability and precision during operation, thereby enabling the relative position between the upper pressure roller 2 and the lower pressure roller 3 to be accurately and permanently maintained stable, which not only avoids unnecessary distortion or deformation of the material during processing, but also significantly improves the overall efficiency of the straightening operation and the quality of the finished product. When the hydraulic cylinder 4 starts to push the movable pressure rod 5 downward, the gap between the movable pressure rod 5 and the top plate 35 increases, and at this time the torsion spring 50 recovers its deformation, causing the inner rotating rod 49 to rotate inside the outer sleeve 48, thereby driving the rotating push rod 51 rotates counterclockwise, so that the top of the rotating push rod 51 pulls one end of the connecting moving rod 54 to move through the slide groove seat 52, and during the movement, the connecting moving rod 54 will move inside the slide groove seat 52, and the moving slide column 55 will move inside the moving groove 53, and pull the anti-rebound block 47 to move to 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, playing a supporting and anti-rebound role. In addition, the torsion spring 50 adopts 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.
