Description

Technical Field

[0001] This invention belongs to the field of rolling mill technology, specifically a silicon steel rolling mill with high-precision plate shape control function. Background Technology

[0002] Silicon steel, as an important soft magnetic alloy material, is widely used in the manufacture of iron cores for power equipment such as transformers, motors, and generators. Its plate shape quality directly affects the magnetic properties of the iron core and the operating efficiency of the equipment. In the production process of silicon steel, the rolling mill is the core equipment for controlling the shape of silicon steel. The silicon steel strip is repeatedly rolled by two extrusion rollers to obtain the required plate shape accuracy and flatness. Existing silicon steel rolling mills usually include a frame, upper and lower extrusion rollers mounted on the frame, and a transmission mechanism for driving the extrusion rollers to rotate.

[0003] However, in actual production, the extrusion rollers are subjected to high temperature, high pressure and alternating loads for a long time. Their outer walls inevitably undergo elastic deformation, thermal deformation and wear, which leads to distortion of the roller gap shape and makes it impossible to achieve high-precision shape control. This results in a decrease in the pass rate of silicon steel products. If the above deformation and wear cannot be detected in time, the shape control system will adjust based on incorrect roller shape data, ultimately failing to achieve high-precision shape control and causing a decrease in the pass rate of silicon steel products. Existing equipment cannot effectively detect the shape of the extrusion roller's outer wall, resulting in a lack of accurate roller shape data support for the shape control system and an inability to achieve high-precision shape control. This has become a key technical bottleneck restricting the improvement of silicon steel sheet shape quality.

[0004] Therefore, the present invention provides a silicon steel rolling mill with high-precision plate shape control function. Summary of the Invention

A set of ball bearings is slidably installed on the inner wall of each collar, and the two sets of ball bearings are respectively in contact with the upper and lower extrusion rolls. Limiting sliders are symmetrically fixedly installed on the outer wall of each ball bearing, and the outer wall of the limiting slider is slidably connected to the inner wall of the collar. An elastic element is fixedly installed between each ball bearing and the corresponding collar. A displacement sensor is fixedly installed on the inner wall of each ball bearing. A connecting assembly is provided between the two collars. A translation assembly is provided below the lower extrusion roll, and a running assembly is provided between the upper and lower extrusion rolls.

[0007] Preferably, the connecting assembly includes a force-bearing bracket and a push rod. Two force-bearing brackets are symmetrically and fixedly installed on the outer wall of the upper collar. Two push rods are symmetrically and fixedly installed on the outer wall of the lower collar. The two push rods are located on the inner side of the two force-bearing brackets, respectively.

[0008] Preferably, a counterweight is slidably installed on the inner wall of one of the force-bearing supports, the counterweight is attached above one of the push rods, a sliding plate is symmetrically fixedly installed on the top of the counterweight, the sliding plate is slidably connected to one of the force-bearing supports, an mounting plate is fixedly installed between the two sliding plates, the mounting plate is located above one of the force-bearing supports, and a distance sensor is fixedly installed on the bottom of the mounting plate.

[0009] Preferably, a laser light is fixedly installed on the inner wall of one of the push rods, and a through hole is opened at the bottom of one of the force-bearing brackets, the through hole being located directly below the laser light.

[0010] Preferably, a connecting plate is fixedly installed at the bottom of one of the force-bearing supports, and a light spot display panel is fixedly installed at the bottom of the connecting plate, the light spot display panel being inclined.

[0011] Preferably, the translation component includes a base located below the lower extrusion roller. A limiting groove is formed on the top of the base. A traveling screw is rotatably mounted on the inner wall of the base. A translation block is slidably mounted on the inner wall of the limiting groove. The inner wall of the translation block is threadedly connected to the outer wall of the traveling screw. A detection component is provided on the top of the translation block. A rotating component is provided on one side of the base.

[0012] Preferably, the detection component includes a mounting base, which is fixedly mounted on the top of the translation block. A rotating shaft is fixedly mounted on the inner wall of the mounting base, and a push plate is rotatably mounted on the outer wall of the rotating shaft. The rotating shaft is located above the middle of the push plate. An angle sensor is provided between the push plate and the rotating shaft. A reset plate is fixedly mounted on the top of the translation block, and the reset plate and the push plate are respectively located on both sides of the lower collar.

[0013] Preferably, the rotating assembly includes a drive motor, which is fixedly mounted on one side of the base. The output shaft of the drive motor is fixedly mounted with a drive wheel, and one end of the traveling screw is fixedly mounted with a driven wheel. A transmission belt is installed between the driven wheel and the drive wheel.

[0014] Preferably, both of the force-bearing supports are fitted with the lower collar, and a limiting slide is fixedly installed on the outer wall of the lower collar. A limiting groove is formed on the top of the base, and the inner wall of the limiting groove is slidably connected to the outer wall of the limiting slide.

[0015] Preferably, the operating assembly includes a frame, two of which are symmetrically fixedly installed on the top of the base. A transmission mechanism is installed on the inner wall of each frame, and the lower extrusion roller is installed between the two transmission mechanisms. A height adjustment seat is slidably installed on the inner wall of each frame, and the upper extrusion roller is installed between the two height adjustment seats. A hydraulic cylinder is fixedly installed on the top of each frame, and the output shaft of each hydraulic cylinder is fixedly connected to the two height adjustment seats respectively. Reinforcing rods are symmetrically fixedly installed between the frames.

[0016] The beneficial effects of this invention are as follows: 1. The collar moves axially along the extrusion roller under the drive of the translation component. At the same time, the extrusion roller itself rotates. The ball bearing, under the action of the elastic element, spirally scans the entire outer wall surface of the roller point by point. With the help of the displacement sensor, data is collected in real time to achieve full coverage and high-resolution detection of the extrusion roller shape. The operator can judge the wear degree and deformation of the extrusion roller based on this data, providing data support for timely maintenance or replacement, and ensuring that the equipment can achieve high-precision shape control.

[0017] 2. This invention uses a distance sensor to detect changes in the distance between the mounting plate and the force support in real time, indirectly reflecting changes in the distance between the upper and lower collars. This allows for accurate judgment of the parallelism of the two extrusion rollers. If the parallelism exceeds the allowable range, the operator can be promptly alerted to make adjustments, thus eliminating plate shape defects caused by non-parallel rollers at the source and effectively ensuring the realization of high-precision plate shape control.

[0018] 3. When the two extrusion rollers are parallel, the laser beam passes precisely through the through hole. When they are not parallel, the beam deviates from the through hole and cannot pass through. Operators do not need to read any instrument data. They can directly judge whether the two rollers are parallel by observing whether the beam passes through the through hole with their naked eyes. The judgment process is intuitive, fast and has no threshold, which greatly reduces the difficulty of judgment and the probability of misoperation for operators. It is especially suitable for rapid on-site inspection and emergency judgment. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 6As shown in the embodiment of the present invention, a silicon steel rolling mill with high-precision plate shape control function includes an upper extrusion roll 1 and a lower extrusion roll 2. The upper extrusion roll 1 is located directly above the lower extrusion roll 2. Both the upper extrusion roll 1 and the lower extrusion roll 2 are fitted with collars 3 on their outer sides. A set of ball bearings 4 is slidably installed on the inner wall of each collar 3. The two sets of ball bearings 4 are respectively in contact with the upper extrusion roll 1 and the lower extrusion roll 2. Limiting sliders 5 are symmetrically fixedly installed on the outer wall of each ball bearing 4. The outer wall of the limiting sliders 5 is slidably connected to the inner wall of the collar 3. An elastic element 6 is fixedly installed between each ball bearing 4 and its corresponding collar 3. A displacement sensor is fixedly installed on the inner wall of each ball bearing 4. Sensor 7, a connecting component is provided between the two collars 3, a translation component is provided below the lower extrusion roller 2, and a rotating component is provided between the upper extrusion roller 1 and the lower extrusion roller 2; during the rolling operation, the rotating component drives the upper extrusion roller 1 and the lower extrusion roller 2 to rotate, and the silicon steel passes between the upper extrusion roller 1 and the lower extrusion roller 2, which shape the silicon steel, thereby realizing the rolling operation. When it is necessary to inspect the extrusion rollers, the translation component and the rotating component are activated. The rotating component drives the upper extrusion roller 1 and the lower extrusion roller 2 to rotate, and the translation component drives the lower collar 3 to move laterally along the extrusion rollers. 3. During movement, the upper collar 3 moves along with the connecting assembly. As the two collars 3 move laterally along the extrusion roller, the two sets of ball bearings 4 pass over the surfaces of the rotating upper extrusion roller 1 and lower extrusion roller 2 respectively. If the surface of the extrusion roller is deformed or worn, the ball bearings 4 will have relative displacement with the collar 3 during movement. The displacement sensor 7 can detect the minute displacement of the ball bearings 4, thereby realizing the detection of the extrusion roller. In summary, the collar 3 moves axially along the extrusion roller under the drive of the translation assembly, while the extrusion roller itself rotates. Under the action of the elastic element 6, the ball bearings 4 spirally scan the entire outer surface of the roller point by point. The wall surface, in conjunction with displacement sensor 7, collects data in real time to achieve full coverage and high-resolution detection of the extrusion roll shape. When there is deformation or wear on the extrusion roll surface, the ball bearing 4 will generate a slight displacement relative to the collar 3 due to the change in surface contour. Displacement sensor 7 accurately quantifies and outputs this slight displacement, which operators can use to judge the degree of wear and deformation of the extrusion roll, providing data support for timely maintenance or replacement, and ensuring that the equipment can achieve high-precision shape control. This detection process can be completed synchronously during the roll operation without disassembly, which greatly improves detection efficiency, reduces the production capacity loss caused by disassembly for inspection, and ensures the continuity of production.

[0024] like Figure 4 and Figure 7As shown, the connecting assembly includes a force-bearing bracket 8 and push rods 9. The force-bearing bracket 8 has two symmetrically fixedly installed on the outer wall of the upper collar 3, and the push rods 9 have two symmetrically fixedly installed on the outer wall of the lower collar 3. The two push rods 9 are located on the inner side of the two force-bearing brackets 8 respectively. When the lower collar 3 moves laterally, it will drive the push rods 9 on both sides to move. When the push rods 9 move, they will drive the upper collar 3 to move through the force-bearing bracket 8. The push rods 9 can slide on the inner side of the force-bearing bracket 8, so as not to affect the height adjustment of the upper extrusion roller 1. The translation detection function and the height adjustment function do not affect each other.

[0025] like Figure 7 As shown, a counterweight 10 is slidably installed on the inner wall of one of the force-bearing supports 8. The counterweight 10 overlaps above one of the push rods 9. A sliding plate 11 is symmetrically fixedly installed on the top of the counterweight 10. The sliding plate 11 is slidably connected to one of the force-bearing supports 8. An mounting plate 12 is fixedly installed between the two sliding plates 11. The mounting plate 12 is located above one of the force-bearing supports 8. A distance sensor 13 is fixedly installed at the bottom of the mounting plate 12. During the rolling operation, the parallelism between the upper extrusion roller 1 and the lower extrusion roller 2 is an important factor affecting the production accuracy. If the two extrusion rollers are not kept parallel, that is, the opening sizes at both ends of the two extrusion rollers are different, it will cause uneven silicon steel thickness during operation. The distance sensor 13 can detect the distance between the mounting plate 12 and the force-bearing support 8. When the two collars 3 move laterally, if the upper extrusion roller 1 and the lower extrusion roller 2 are not kept parallel, the distance between the two collars 3 will change, and the relative position of the push rod 9 and the force-bearing support 8 will change. The push rod 9 will slide inside the force-bearing support 8. After the push rod 9 slides... This causes the counterweight 10 to slide. When the counterweight 10 slides, it drives the mounting plate 12 to move via the sliding plate 11. After the mounting plate 12 moves, the distance between it and the force support 8 will change. The distance sensor 13 will detect the change in the distance between the mounting plate 12 and the force support 8, thereby reminding the operator. If the upper extrusion roller 1 and the lower extrusion roller 2 are parallel, then the distance between the mounting plate 12 and the force support 8 remains unchanged. In summary, this invention uses the distance sensor 13 to detect the change in the distance between the mounting plate 12 and the force support 8 in real time, indirectly reflecting the change in the distance between the upper and lower collars 3, thereby accurately judging the parallelism of the two extrusion rollers. Once the parallelism exceeds the allowable range, the operator can be promptly reminded to make adjustments, eliminating plate shape defects caused by non-parallelism of the roller system from the source, and effectively ensuring the realization of high-precision plate shape control function. Through the distance sensor 13, the operator can directly read the deviation value of parallelism, thereby accurately calculating the required adjustment amount, quickly and accurately correcting the parallelism of the extrusion rollers, and greatly improving the adjustment efficiency and adjustment accuracy.

[0026] like Figure 7As shown, a laser lamp 14 is fixedly installed on the inner wall of one of the push rods 9, and a through hole 15 is opened at the bottom of one of the force-bearing supports 8, located directly below the laser lamp 14. When the upper extrusion roller 1 and the lower extrusion roller 2 are parallel, the light beam emitted by the laser lamp 14 will pass through the through hole 15. If the upper extrusion roller 1 and the lower extrusion roller 2 are not parallel, the push rod 9 and the force-bearing support 8 will rotate relative to each other, and the laser lamp 14 and the through hole 15 will no longer be aligned. Therefore, the light beam cannot pass through the through hole 15. By observing whether the light beam emitted by the laser lamp 14 passes through the through hole 15, it can be determined whether the two extrusion rollers are parallel. In summary, when the two extrusion rollers are parallel, the laser beam accurately passes through the through hole 15; when they are not parallel, the light beam deviates from the through hole 15 and cannot pass through. Operators do not need to read any instrument data; they can directly determine whether the two rollers are parallel simply by visually observing whether the light beam passes through the through hole 15. The judgment process is intuitive, fast, and barrier-free, greatly reducing the difficulty of judgment and the probability of misoperation for operators. It is especially suitable for rapid on-site inspection and emergency judgment. The laser detection component serves as a secondary verification method for the distance sensor 13. When the results of the two detection methods are consistent, the parallelism status can be highly assured. When the distance sensor 13 malfunctions or the data is abnormal, the laser component can still provide a reliable qualitative judgment basis, effectively preventing operators from making incorrect adjustment decisions due to false alarms from a single sensor. This avoids batch scrap and production losses caused by parallelism judgment errors, providing double safety protection for high-precision plate shape control.

[0027] like Figure 7 As shown, a connecting plate 16 is fixedly installed at the bottom of one of the force-bearing supports 8, and a light spot display plate 17 is fixedly installed at the bottom of the connecting plate 16. The light spot display plate 17 is set at an angle. When the beam of the laser lamp 14 passes through the through hole 15, the beam will shine on the light spot display plate 17 to form a light spot. The operator only needs to observe whether there is a light spot on the light spot display plate 17 to determine whether the two extrusion rollers are parallel. The light spot display plate 17 is set at an angle so that its surface faces the operator's natural observation direction. The operator can see the light spot directly without having to deliberately adjust the viewing angle. In addition, in order to make the observation work better, the light emitted by the laser lamp 14 is different in color from that of the light spot display plate 17, so that the light spot forms a strong color contrast on the light spot display plate 17.

[0028] like Figure 3 and Figure 8As shown, the translation assembly includes a base 18 located below the lower extrusion roller 2. A limiting groove 19 is formed on the top of the base 18. A traveling screw 20 is rotatably mounted on the inner wall of the base 18. A translation block 21 is slidably mounted on the inner wall of the limiting groove 19. The inner wall of the translation block 21 is threadedly connected to the outer wall of the traveling screw 20. A detection assembly is located on the top of the translation block 21, and a rotating assembly is located on one side of the base 18. During detection, the rotating assembly is activated, causing the traveling screw 20 to rotate. The rotation of the traveling screw 20, via the thread, causes the translation block 21 to move laterally along the limiting groove 19. The movement of the translation block 21 causes the detection assembly to move, which in turn pushes the lower collar 3, thus providing power for the detection operation.

[0029] like Figures 8 to 9As shown, the detection assembly includes a mounting base 22, which is fixedly mounted on the top of the translation block 21. A rotating shaft 23 is fixedly mounted on the inner wall of the mounting base 22, and a push plate 24 is rotatably mounted on the outer wall of the rotating shaft 23. The rotating shaft 23 is located above the center of the push plate 24. An angle sensor is disposed between the push plate 24 and the rotating shaft 23. A reset plate 25 is fixedly mounted on the top of the translation block 21. The reset plate 25 and the push plate 24 are located on opposite sides of the lower collar 3, respectively. During detection, the translation block 21 moves the mounting base 22. When the mounting base 22 moves, it moves the push plate 24 via the rotating shaft 23. After the push plate 24 comes into contact with the lower collar 3, it pushes the collar 3 to move, thereby... During the testing process, the rotating shaft 23 is located above the center of the push plate 24. Therefore, initially, the push plate 24 is vertical under the influence of gravity. When the push plate 24 is in contact with the collar 3, if the lower extrusion roller 2 remains horizontal, the lower collar 3 will remain vertical. Thus, the push plate 24 will continue to remain vertical after being in contact with the lower collar 3. If the lower extrusion roller 2 tilts, the lower collar 3 will also tilt. Therefore, when the push plate 24 is in contact with the collar 3, it will adaptively rotate around the rotating shaft 23 to maintain contact with the tilted collar 3. The angle sensor can detect the rotation of the push plate 24. When the angle sensor does not detect any rotation of the push plate 24... When the angle changes, it indicates that the lower extrusion roller 2 is in a horizontal state; conversely, it indicates that the lower extrusion roller 2 is tilted. The reset plate 25 is used to drive the collar 3 to reset when the translation block 21 moves in the opposite direction. In summary, after the push plate 24 is in contact with the lower collar 3, if the angle sensor does not detect an angle change in the push plate 24, it means that the push plate 24 always remains vertical, that is, the collar 3 remains vertical, thus indicating that the lower extrusion roller 2 is in a horizontal state. Conversely, if the angle sensor detects an angle deflection in the push plate 24, it means that the collar 3 has tilted, thus indicating that the lower extrusion roller 2 is tilted. By detecting whether the lower extrusion roller 2 is horizontal, combined with detecting whether the two extrusion rollers are parallel, the two are linked... When used together, this invention can simultaneously acquire the levelness data of the lower extrusion roller 2 and the parallelism data of the upper and lower rollers. If the lower roller is level and the upper and lower rollers are parallel, the roller system is in the optimal working state. If the lower roller is tilted or the upper and lower rollers are not parallel, each of these conditions can be independently detected by its respective detection mechanism. This joint detection mechanism enables comprehensive monitoring of the spatial posture of the roller system, covering everything from the levelness of a single roller to the parallelism of two rollers, without any blind spots. It provides complete roller system status data for high-precision plate shape control. This invention can simultaneously acquire three sets of key data: the surface shape of the extrusion roller, the levelness of the lower roller, and the parallelism of the upper and lower rollers. The detection efficiency is extremely high, and the three sets of data are collected at the same time and under the same working conditions, exhibiting good time synchronization and data correlation.

[0030] like Figure 2 and Figure 8As shown, the rotating assembly includes a drive motor 26, which is fixedly mounted on one side of the base 18. The output shaft of the drive motor 26 is fixedly mounted with a drive wheel 27, and one end of the traveling screw 20 is fixedly mounted with a driven wheel 28. A transmission belt 29 is installed between the driven wheel 28 and the drive wheel 27. When the drive motor 26 is started, it drives the drive wheel 27 to rotate. When the drive wheel 27 rotates, it drives the driven wheel 28 to rotate through the transmission belt 29. When the driven wheel 28 rotates, it drives the traveling screw 20 to rotate, thereby providing power for the detection work.

[0031] like Figure 2 and Figure 4 As shown, both force-bearing supports 8 are in contact with the lower collar 3. A limiting slide 30 is fixedly installed on the outer wall of the lower collar 3. A limiting groove 31 is opened on the top of the base 18. The inner wall of the limiting groove 31 is slidably connected to the outer wall of the limiting slide 30. The two force-bearing supports 8 are in contact with the lower collar 3, thereby limiting the upper collar 3 and preventing it from rotating. The limiting slide 30 and the limiting groove 31 limit the lower collar 3 and prevent it from rotating. By limiting the rotation direction of the two collars 3, the collars 3 are prevented from rotating around the extrusion roller, thus ensuring the detection accuracy of the detection work.

[0032] like Figures 1 to 2 As shown, the operating components include a frame 32, two of which are symmetrically fixedly installed on the top of the base 18. A transmission mechanism 33 is installed on the inner wall of each frame 32. The lower extrusion roller 2 is installed between the two transmission mechanisms 33. A height adjustment seat 34 is slidably installed on the inner wall of each frame 32, and the upper extrusion roller 1 is installed between the two height adjustment seats 34. A hydraulic cylinder 35 is fixedly installed on the top of each frame 32, and the output shaft of the hydraulic cylinder 35 is fixedly connected to the two height adjustment seats 34 respectively. Reinforcing rods 36 are symmetrically fixedly installed between the frames 32. During the rolling operation, the extrusion rollers are driven to rotate through the transmission structure, and silicon steel passes between the upper extrusion roller 1 and the lower extrusion roller 2, thereby achieving the shaping process. The height of the two height adjustment seats 34 can be adjusted by the hydraulic cylinder 35, thereby adjusting the height of the upper extrusion roller 1, enabling the device to meet different production needs.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
