Description

Technical Field

[0001] This utility model belongs to the field of continuous rolling mill stand detection and correction technology, specifically a continuous rolling mill stand detection and correction platform. Background Technology

[0002] In modern steel rolling production, continuous rolling mills play a crucial role. Precise alignment of the axial and radial centerlines of the rolls on each stand of a continuous rolling mill is a key factor in ensuring the stability of the rolling line, the dimensional accuracy of the rolled material, and product quality. A stable rolling line ensures that the rolled material passes smoothly through each stand during the rolling process, reducing deviation and twisting of the rolled material, thereby improving production efficiency and product yield. Precise roll centerline alignment helps to accurately control the dimensional accuracy of the rolled material, ensuring that key dimensions such as thickness and width meet design requirements, thus improving product quality and market competitiveness.

[0003] Chinese patent CN203227674U discloses a calibration device for the centerline of the rolling mill hole in a continuous rolling mill. The device includes a programmable industrial control computer, a target ring mounted on the stand at the entrance of the rolling mill hole, a rolling mill roll, and a photographic device positioned outside the exit of the continuous rolling mill. This device utilizes image processing calibration methods to achieve online calibration of the rolling mill hole centerline, solving the error problem caused by centerline deviation during roll processing. However, this device can only indirectly determine the centerline by observing the wear of the T-head, lacking quantitative evidence. Furthermore, the radial clearance caused by wear of key components such as bearing housings, roll shafts, and bearings is difficult to measure accurately online, making it impossible to accurately determine the actual radial center position of the roll. Additionally, the design clearance of the bearing itself and the clearance generated during assembly contribute to errors in offline measurement, making it impossible to accurately measure the axial centerline of the rolling mill roll under online rolling conditions.

[0004] Therefore, there is an urgent need for a continuous rolling mill stand inspection and correction platform that allows the continuous rolling mill stand to utilize the weight of the bearing housing and the rolls themselves to eliminate the radial fit clearance between the bearing housing and the rolls, inside the bearings, and between the bearings and the shaft. This enables the accurate calculation of the radial center position of the rolls, the wear compensation value of each T-head face, and the accurate axial centerline dimension of the rolls, thereby improving the accuracy of axial measurement. Utility Model Content

[0005] The purpose of this utility model is to provide a continuous rolling mill stand inspection and correction platform to solve at least one aspect of the problems and defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A continuous rolling mill stand inspection and calibration platform, comprising: V-shaped base, the top of the V-shaped base is provided with a correction device, the correction device includes a radial positioning surface, and a continuous rolling mill stand is provided inside the correction device; The continuous rolling mill stand includes a bearing housing, and the bearing housing is provided with rolling rolls; The continuous rolling mill stand is equipped with a positioning block at the rear of the rolls. One end of the positioning block is connected to the bearing seat, and the other end is connected to the top of the correction device. The bearing housing and the top of the positioning block are respectively provided with T-shaped heads.

[0007] The continuous rolling mill stand inspection and correction platform according to this utility model has at least the following technical effects: When measurements are required, the rolling mill stand is installed on the calibration platform. Without hydraulic balancing, the bearing housings and rolls of the rolling mill stand naturally droop towards one end of the roll due to their own weight, causing the roll end face to contact the radial positioning surface of the calibration device. This eliminates radial clearances between the bearing housing and the roll, within the bearing, and between the bearing and the shaft, restoring it to a center position similar to when subjected to rolling force. Then, using measuring tools, the distance from the bottom of the V-shaped base to the top plane of the T-head is measured, allowing for precise calculation of the roll's radial center position and the wear compensation value for each T-head surface. Furthermore, through the self-weight of the rolling mill stand and the cooperation of the V-shaped base, the rolling mill stand can effectively simulate the online rolling state, eliminating axial assembly clearances through its own weight. Then, using measuring tools, the distance from the axial positioning block to the roll end face is precisely measured, thereby accurately calculating the precise axial centerline dimension of the roll.

[0008] This continuous rolling mill stand inspection and correction platform uses a V-shaped base and a correction device tilted on top of the V-shaped base. The continuous rolling mill stand is placed inside the correction device, allowing the stand to tilt towards the rolls using the weight of the bearing housings and the rolls themselves. The contact between the rolls and the radial positioning surface of the correction device eliminates the radial clearances between the bearing housings and the rolls, inside the bearings, and between the bearings and the shaft. This restores the rolls to a center position similar to when they are subjected to rolling forces. This allows the distance from the bottom of the V-shaped base to the top plane of the T-head to be measured using measuring tools, thereby accurately calculating the radial center position of the rolls and the wear compensation value of each T-head surface. This provides a quantitative basis for radial measurement, changing the previous situation where the only way to indirectly judge the condition was by observing the wear of the T-heads.

[0009] Furthermore, due to the presence of bearing design clearance and assembly gap, offline measurement errors are large, making it difficult to accurately measure the axial centerline of the continuous rolling mill rolls under online rolling conditions. This platform effectively simulates the online rolling state by using the self-weight of the continuous rolling mill stand in conjunction with a V-shaped base, eliminating the assembly gap in the axial direction. Then, by using measuring tools to accurately measure the distance from the axial positioning block to the roll end face, the accurate dimension of the roll's axial centerline can be calculated precisely, greatly improving the accuracy of axial measurement.

[0010] As a further embodiment of this utility model: the V-shaped base includes a base plate, and side walls are respectively provided on both sides of the base plate, with V-shaped grooves extending from the middle of the side walls to the bottom.

[0011] As a further embodiment of this utility model: the correction device includes two side plates, which are inclinedly arranged in the V-groove.

[0012] The V-shaped base includes a base plate with side walls on both sides. A V-shaped groove extends from the center of each side wall towards the bottom. The correction device includes two side plates, which are inclined within the V-shaped groove. The V-shaped groove design provides a precise positioning reference for the continuous rolling mill stand. When the side plates of the correction device are inclined within the V-shaped groove, the two inclined surfaces of the V-shaped groove can limit the side plates from different directions, ensuring that the correction device and the continuous rolling mill stand installed within it are accurately fixed on the horizontal plane. This reduces the possibility of lateral displacement of the continuous rolling mill stand during measurement, allowing the continuous rolling mill stand to naturally droop towards one end of the roll using the weight of the bearing housing and the roll itself. The contact between the roll and the radial positioning surface of the correction device effectively eliminates radial clearances between the bearing housing and the roll, inside the bearing, and between the bearing and the shaft, as well as axial assembly clearances. This more realistically simulates the online rolling state, providing excellent conditions for accurate measurement and ensuring the realism of the simulation and the reliability of the measurement results.

[0013] As a further embodiment of this utility model: the correction device further includes a rear plate, and an inclined frame is provided in the middle of the base plate, with the rear plate abutting against the inclined frame.

[0014] As a further improvement of this utility model, the tilt angle of the tilting frame is adapted to the groove angle of the V-shaped groove.

[0015] Since the correction device also includes a back plate, and an inclined frame is provided in the middle of the base plate, the back plate abuts against the inclined frame; the inclination angle of the inclined frame is adapted to the groove angle of the V-shaped groove; the back plate and the inclined frame abut against each other to form a stable triangular support structure, which can effectively disperse the pressure applied to the V-shaped base by the continuous rolling mill stand and the correction device, avoid local stress concentration, enhance the overall structural strength and load-bearing capacity of the V-shaped base, reduce base deformation caused by uneven force, and ensure the stability of the base during the measurement process.

[0016] As a further improvement of this utility model, the groove opening angle of the V-shaped groove is 90°.

[0017] Because the V-groove opening angle is 90°, the correction device can maintain a 45° tilt within the V-groove. When the continuous rolling mill stand is placed behind the correction device, the tilted device allows the stand to tilt towards one end of the roll due to the weight of the bearing housing and the roll itself. This causes the roll end face to contact the radial positioning surface of the correction device, eliminating radial clearances between the bearing housing and the roll, inside the bearing, and between the bearing and the shaft. This provides a good foundation for subsequent accurate measurement of the roll's radial center position. The data obtained through measuring tools accurately reflects the actual state of the roll, avoiding measurement errors caused by clearances, thus greatly improving measurement accuracy and reliability.

[0018] As a further embodiment of this utility model: a positioning plate is provided across the two sides of the side plate, a measuring hole is provided on the top of the positioning block, and a through hole corresponding to the measuring hole is provided on the positioning plate.

[0019] By setting a positioning plate across both side plates, and setting a measuring hole on the top of the positioning block, and setting through holes on the positioning plate corresponding to the measuring hole, a stable and uniform reference plane is provided for the measurement work. This ensures that the measuring tool can be accurately aligned with the measuring hole, avoiding measurement errors caused by measurement position deviation. This allows for more accurate results when measuring dimensions such as the distance from the axial positioning block to the end face of the roll, thus providing reliable data support for accurately calculating the axial centerline dimensions of the roll.

[0020] As a further embodiment of this utility model: a frame slider is detachably provided on the top of the side plate, and one end of the positioning block is connected to the frame slider.

[0021] As a further improvement of this utility model, the thickness of the frame slider is 17mm-24mm.

[0022] Because the top of the side plate is detachably equipped with a frame slider, one end of the positioning block is connected to the frame slider, and the thickness of the frame slider is 17mm-24mm; by adjusting the thickness of the frame slider, the axial compensation value can be adjusted, thereby correcting and calibrating the axial center, effectively reducing the installation error of the continuous rolling mill stand, and ensuring that the distance from the axial positioning block to the end face of the roll can be accurately measured by measuring tools, thereby accurately calculating the accurate dimension of the axial centerline of the roll.

[0023] As a further improvement of this utility model, a groove is provided in the middle of the T-shaped head.

[0024] Because the T-head has a groove in the middle for the hydraulic cylinder connecting rod to pass through, it prevents interference with the hydraulic cylinder connecting rod, allowing it to move smoothly and avoiding direct contact and collision with the T-head, thus ensuring the stability of the equipment operation.

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0034] like Figure 1-6The embodiment of this utility model shows a continuous rolling mill stand inspection and correction platform, comprising: a V-shaped base 1, a correction device 2 disposed on the top of the V-shaped base 1, the correction device including a radial positioning surface 205, and a continuous rolling mill stand 3 disposed inside the correction device 2; the continuous rolling mill stand 3 includes a bearing seat 301, and a roll 302 disposed inside the bearing seat 301; a positioning block 303 is disposed at the rear of the roll 302 on the continuous rolling mill stand 3, one end of the positioning block 303 being connected to the bearing seat 301, and the other end being connected to the top of the correction device 2; a T-shaped head 304 is respectively disposed on the top of the bearing seat 301 and the positioning block 303.

[0035] In use, when measurement is required, the continuous rolling mill stand 3 is installed on the correction platform. Without hydraulic balancing force, the bearing housing 301 and roll 302 of the continuous rolling mill stand 3 naturally droop towards one end of the roll 302 under their own weight, causing the end face of the roll 302 to contact the radial positioning surface 205 of the correction device 2. This eliminates the radial fit clearance between the bearing housing 301 and the roll 302, inside the bearing, and between the bearing and the shaft, restoring it to a position similar to the center position when subjected to rolling force. Then, a measuring tool is used... By measuring the distance from the bottom of the V-shaped base 1 to the top plane of the T-head 304, the radial center position of the roll 302 and the wear compensation value of each T-head face can be accurately calculated. Furthermore, by using the self-weight of the continuous rolling mill stand 3 in conjunction with the V-shaped base 1, the continuous rolling mill stand 3 can effectively simulate the online rolling state. The axial assembly gap is eliminated by the weight of the stand itself. Then, by using measuring tools, the distance from the axial positioning block 303 to the end face of the roll 302 can be accurately measured, thereby accurately calculating the accurate dimension of the axial centerline of the roll 302.

[0036] Specifically, the continuous rolling mill stand inspection and correction platform uses a V-shaped base 1 and a correction device 2 tilted on top of the V-shaped base 1. The continuous rolling mill stand 3 is placed inside the correction device 2. The continuous rolling mill stand 3 tilts towards the roll 302 using the weight of the bearing housing 301 and the roll 302. The roll 302 contacts the radial positioning surface 205 of the correction device 2, eliminating the radial fit clearance between the bearing housing 301 and the roll 302, inside the bearing, and between the bearing and the shaft. This restores the roll 302 to a center position similar to when it is bearing rolling force. In this way, the distance from the bottom of the V-shaped base 1 to the top plane of the T-head 304 can be measured using measuring tools. This allows for the accurate calculation of the radial center position of the roll 302 and the wear compensation value of each T-head surface, providing a quantitative basis for radial measurement and changing the previous situation where the wear of the T-head could only be indirectly judged by observing the wear of the T-head.

[0037] Furthermore, due to the bearing design clearance and assembly gap, offline measurement errors are large, making it difficult to accurately measure the axial centerline of the continuous rolling mill rolls under online rolling conditions. This platform effectively simulates the online rolling state by using the self-weight of the continuous rolling mill stand 3 in conjunction with the V-shaped base 1, eliminating the assembly gap in the axial direction. Then, by using measuring tools to accurately measure the distance from the axial positioning block 303 to the end face of the roll 302, the accurate dimension of the axial centerline of the roll 302 can be accurately calculated, greatly improving the accuracy of axial measurement.

[0038] Furthermore, such as Figure 1 and Figure 3 As shown, the V-shaped base 1 includes a base plate 101, and side walls 102 are respectively provided on both sides of the base plate 101. V-shaped grooves 103 are provided in the middle of the side walls 102 extending to the bottom. The correction device 2 includes two side plates 201, and the two side plates 201 are inclinedly arranged in the V-shaped grooves 103.

[0039] Specifically, the V-shaped base 1 includes a base plate 101, with side walls 102 on both sides of the base plate 101, and V-shaped grooves 103 extending from the middle of the side walls 102 to the bottom; the straightening device 2 includes two side plates 201, which are inclinedly arranged in the V-shaped grooves 103; the design of the V-shaped grooves 103 provides a precise positioning reference for the continuous rolling mill stand 3. When the side plates 201 of the straightening device 2 are inclinedly arranged in the V-shaped grooves 103, the two inclined surfaces of the V-shaped grooves 103 can limit the side plates 201 from different directions, ensuring that the straightening device 2 and the continuous rolling mill stand 3 installed therein are on the horizontal plane. The accurate and fixed position reduces the possibility of lateral displacement of the continuous rolling mill stand 3 during the measurement process. This allows the continuous rolling mill stand 3 to naturally droop towards one end of the roll 302 using the weight of the bearing housing 301 and the roll 302 itself. The roll 302 then contacts the radial positioning surface 205 of the correction device 2, effectively eliminating the radial fit clearance between the bearing housing 301 and the roll 302, inside the bearing, and between the bearing and the shaft, as well as the axial assembly clearance. This more realistically simulates the online rolling state, providing good conditions for accurate measurement and ensuring the authenticity of the simulation and the reliability of the measurement results.

[0040] Furthermore, such as Figure 2 and Figure 4 As shown, the correction device 2 also includes a rear plate 202, and an inclined frame 104 is provided in the middle of the base plate 101. The rear plate 202 abuts against the inclined frame 104. The inclination angle of the inclined frame 104 is adapted to the groove angle of the V-groove 103.

[0041] Specifically, since the correction device 2 also includes a back plate 202, and an inclined frame 104 is provided in the middle of the base plate 101, the back plate 202 abuts against the inclined frame 104; the inclination angle of the inclined frame 104 is adapted to the groove angle of the V-groove 103; the back plate 202 abuts against the inclined frame 104 to form a stable triangular support structure, which can effectively disperse the pressure applied to the V-shaped base 1 by the continuous rolling mill stand 3 and the correction device 2, avoid local stress concentration, enhance the overall structural strength and load-bearing capacity of the V-shaped base 1, reduce base deformation caused by uneven force, and ensure the stability of the base during the measurement process.

[0042] Furthermore, the groove angle of the V-groove 103 is 90°.

[0043] Specifically, since the groove angle of the V-groove 103 is 90°, the correction device 2 can maintain a 45° tilt within the V-groove 103. Thus, when the continuous rolling mill stand 3 is placed in the correction device 2, the tilted correction device 2 can cause the continuous rolling mill stand 3 to tilt towards one end of the roll 302 by the weight of the bearing seat 301 and the roll 302 itself. This causes the end face of the roll 302 to contact the radial positioning surface 205 of the correction device 2, thereby eliminating the radial fit clearance between the bearing seat 301 and the roll 302, inside the bearing, and between the bearing and the shaft. This provides a good foundation for the subsequent accurate measurement of the radial center position of the roll. The data obtained by the measuring tool can truly reflect the actual state of the roll 302, avoiding measurement errors caused by fit clearance, thus greatly improving the accuracy and reliability of the measurement.

[0044] Furthermore, such as Figure 5 As shown, a positioning plate 203 is provided across the two side plates 201, a measuring hole is provided on the top of the positioning block 303, and a through hole 2031 corresponding to the measuring hole is provided on the positioning plate 203.

[0045] Specifically, a positioning plate 203 is set across the two side plates 201, and a measuring hole is set on the top of the positioning block 303. The positioning plate 203 is provided with a through hole 2031 corresponding to the measuring hole, which provides a stable and uniform reference plane for the measurement work. This ensures that the measuring tool can be accurately aligned with the measuring hole, avoiding measurement errors caused by measurement position deviation. This allows for more accurate results when measuring dimensions such as the distance from the axial positioning block 303 to the end face of the roll 302, thus providing reliable data support for accurately calculating the axial centerline dimensions of the roll 302.

[0046] Furthermore, such as Figure 2 and Figure 3 As shown, a frame slider 204 is detachably mounted on the top of the side plate 201, and one end of the positioning block 303 is connected to the frame slider 204; the thickness of the frame slider 204 is 17mm-24mm.

[0047] Specifically, since the top of the side plate 201 is detachably equipped with a frame slider 204, one end of the positioning block 303 is connected to the frame slider 204, and the thickness of the frame slider 204 is 17mm-24mm; by adjusting the thickness of the frame slider 204, the axial compensation value can be adjusted, thereby correcting and calibrating the axial center, effectively reducing the installation error of the continuous rolling mill stand 3, and ensuring that the distance from the axial positioning block 303 to the end face of the roll 302 can be accurately measured by measuring tools, thereby accurately calculating the accurate dimension of the axial centerline of the roll 302.

[0048] It should also be noted that, as Figure 5 As shown, a groove 3041 is provided in the middle of the T-head 304.

[0049] Specifically, the T-head 304 has a groove 3041 in the middle for the hydraulic cylinder connecting rod to pass through, preventing interference with the hydraulic cylinder connecting rod and allowing it to move smoothly. This avoids direct contact and collision with the T-head 304, ensuring the stability of the equipment operation.

[0050] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
