TECHNICAL FIELD
[0001] The present application relates to the technical field of steel rolling equipment, in particular to a guide pinch roll deviation rectifying device and method. BACKGROUND
[0002] The common production process of modern cold-rolled sheet production is: pickling, cold rolling, electrolytic cleaning, bell-type furnace annealing, leveling, finishing (cross cutting, slitting, re-coiling), and finished product (sheet, coil) packaging. In the early 1970s, a new production process appeared, which combined the five separate production processes of electrolytic cleaning after cold rolling, bell-type annealing, steel coil cooling, conditioning rolling (leveling), and finishing inspection into a production unit, and used a vertical continuous furnace to replace the intermittent bell-type furnace, realizing continuous production. This continuous production line is called a continuous annealing unit, abbreviated as CAPL.
[0003] In a cold-rolled continuous annealing unit, the guide pinch roll is a key device before the steel strip is coiled, which functions to guide and stabilize the delivery of the steel strip to ensure that the coiling is neat and the tension is uniform. However, in actual production, due to factors such as fluctuations in steel strip tension, incoming plate shape deviation (such as camber and edge wave), or installation errors of the equipment, the steel strip is prone to lateral deviation. If the deviation problem is not corrected in time, it will lead to uneven coiling (such as tower-shaped coil, loose coil), damage to the edge of the steel strip, and even affect the quality of subsequent processing.
[0004] The traditional deviation rectifying method mainly relies on manual adjustment or fixed guide rollers, which has low rectifying accuracy and slow response speed, making it difficult to meet the needs of high-speed continuous production. Although some units use automatic deviation rectifying devices (such as CPC systems), they are usually independent of the pinch roll, which has a complex structure and occupies a large space, increasing the cost of equipment and the difficulty of maintenance. In addition, the existing deviation rectifying mechanism has insufficient adjustment flexibility when dealing with different specifications of steel strips, affecting the production efficiency and stability of product quality.

[0016] A guiding pinch roll deviation rectifying method, specifically comprising the following steps:
[0017] 1) If the height difference between the one end of the guide pinch roll and the other end of the guide pinch roll appears, and the one end of the guide pinch roll is higher than the other end of the guide pinch roll, the first hand wheel is rotated to drive the wedge to move inward, the height of the one end of the guide pinch roll is lowered, and the height direction deviation is corrected;
[0018] 2) If the height difference between the one end of the guide pinch roll and the other end of the guide pinch roll appears, and the one end of the guide pinch roll is lower than the other end of the guide pinch roll, the first hand wheel is rotated to drive the wedge to move outward, the height of the one end of the guide pinch roll is increased, and the height direction deviation is corrected;

[0020] Compared with the prior art, the present application has at least the following technical effects or advantages:
[0021] 1) The present application realizes high-precision lifting adjustment of the one end of the guide pinch roll through the cooperation of the upper inclined block, the positioning inclined block, the wedge and the lower sliding block, has the significant advantages of fast deviation correction response and high precision, the wedge can efficiently convert horizontal displacement into vertical lifting movement when moving along the inclined sliding groove and the sliding groove, the one end (operation side) of the guide pinch roll is quickly adjusted in height, so that the steel strip deviation problem is accurately corrected; the device adopts a modular design of inclined surface sliding cooperation, has compact structure and convenient installation, reduces the complex transmission mechanism of the traditional deviation correction device, and is convenient for installation and maintenance in limited space; the sliding contact surface of the inclined block and the sliding groove is precisely machined, has the characteristics of stable operation and small wear, and is not easy to produce jamming in long-term use; the lifting amplitude can be accurately controlled by adjusting the displacement of the wedge, the adjustment is flexible and has strong adaptability, and can meet the deviation correction needs of different specifications of steel strips; the present application provides an efficient and reliable steel strip deviation correction solution for the cold rolling continuous annealing unit.
[0022] 2、The present application adds a first linear movement device composed of a first screw rod and a first nut, so that the displacement adjustment of the wedge block is realized by precise and controllable mechanical operation. The rotation is converted into linear displacement through the threaded pair, which not only significantly improves the accuracy and stability of the deviation correction operation, but also effectively avoids the drift phenomenon that may occur in the traditional hydraulic system through the mechanical self-locking characteristic. The screw rod transmission mechanism has a torque amplification effect, and the operator only needs to exert a small torque to realize the large thrust movement of the wedge block, which not only reduces the manual adjustment strength, but also ensures the impact resistance in the high-speed running condition of the steel belt. The structure adopts a standardized threaded assembly, and the wear parts can be directly replaced during maintenance, which reduces the maintenance cost by more than 60% compared with a complex servo system, while retaining the reliability advantage of pure mechanical transmission, and is especially suitable for long-term stable work in the harsh environment of the rolling mill workshop with much dust and high vibration.
[0023] 3、The cooperation of the first T-shaped groove and the first runner is equivalent to the shaft sleeve movement pair in the sliding bearing, and the runner rotates freely in the T-shaped groove while avoiding axial movement. Compared with the rolling bearing, the present application does not need to be maintained, and the service life and reliability are improved.
[0024] 4、The present application rotates the first screw rod by the first hand wheel, and the humanized design of the first hand wheel at the end of the first screw rod significantly improves the operation convenience and saves labor.
[0025] 5、Under normal circumstances, the axis of the guide pinch roll is perpendicular to the running direction of the steel belt, and the included angle between the two should be 90°. The axis at this time is set as the reference line, and the reference line passes through the center of the guide pinch roll and is perpendicular to the running direction of the steel belt. After the guide pinch roll is deflected, the axis of the guide pinch roll and the reference line form an included angle. By rotating the second linear movement device to drive the lower sliding block to move along the running direction of the steel belt, the guide pinch roll is adjusted to make the axis of the guide pinch roll coincide with the reference line, so that the deviation in the horizontal direction is corrected.
[0026] The original lifting adjustment mechanism cooperates to make the guide pinch roll have vertical lifting and horizontal swing angle adjustment capabilities. This "lifting + swing angle" compound deviation correction mode can effectively compensate for the three-dimensional deviation of the steel belt.
[0027] 6、The second screw rod end of the present application is provided with a second hand wheel, which is arranged at 90° with the first hand wheel. The operator can complete three-dimensional adjustment at the same station. DETAILED DESCRIPTION

[0042] As Figure 6 , 7 As shown in the drawings, the present application is a guide pinch roll deviation correcting device, which is installed at the bottom of the right side (operation side) side plate 1 of the swing arm frame. The left and right ends of the guide pinch roll 8 are installed on the self-aligning roller bearing, and the self-aligning roller bearing is installed in the bearing seat. The bearing seat of the operation side (right end) of the guide pinch roll 8 is installed in the present device, and the bearing seat of the transmission side (left end) of the guide pinch roll 8 is installed on the left side (transmission side) of the swing arm frame.
[0043] The up-and-down and front-and-back swing of the guide pinch roll 8 is realized by the self-aligning ability of the self-aligning roller bearing. Since the self-aligning angle is limited, the maximum stroke of the guide pinch roll 8 in the up-and-down direction on the operating side is ±6 mm, and the maximum stroke of the guide pinch roll 8 in the front-and-back direction on the operating side is ±10 mm.
[0044] As shown in Figures 1-3 , the device comprises an upper inclined block 2, a positioning inclined block 3, a wedge block 4, a lower sliding block 5, a first linear moving device 6 and a second linear moving device 7.
[0045] The top surface of the upper inclined block 2 is fixed to the bottom surface of the right side (operating side) side plate 1 of the swing arm frame by bolts. The middle of the upper inclined block 2 is provided with a first inclined surface 21 inclined upward from back to front.
[0046] The two positioning inclined blocks 3 are fixed to the bottom of the upper inclined block 2 by bolts. The positioning inclined block 3 is provided with a second inclined surface 31 with the same inclination as the first inclined surface 21 of the upper inclined block 2. The first inclined surface 21 and the second inclined surface 31 are provided with a spacing to form an inclined sliding groove. The inclined sliding groove is perpendicular to the running direction of the steel belt and parallel to the axis of the guide pinch roll 8 (in the normal state of the guide pinch roll 8).
[0047] The wedge block 4 is in the shape of an I-beam and is provided with an upper sliding plate 41, a lower sliding plate 42 and a first T-shaped groove 43. The upper sliding plate 41 is a rectangular plate inclined upward from back to front. The lower sliding plate 42 is a horizontal rectangular plate. The first T-shaped groove 43 is provided at the front end of the rectangular block between the upper sliding plate 41 and the lower sliding plate 42.
[0048] The upper sliding plate 41 is installed in the inclined sliding groove formed by the first inclined surface 21 and the second inclined surface 31 and can move forward and backward along the inclined sliding groove.
[0049] The lower sliding block 5 is provided with a T-shaped sliding groove 51 corresponding to the lower sliding plate 42 and is connected to the lower sliding plate 42 through the sliding groove 51. The left side of the lower sliding block 5 is provided with a second T-shaped groove 52. The bearing seat at the right end of the guide pinch roll 8 is fixed to the bottom of the lower sliding block 5 by bolts.
[0050] As shown in Figures 1-4 , the first linear moving device 6 comprises a first screw rod 61, a first nut 62, a first hand wheel 63, a support frame 64 and a first rotating wheel 65. The support frame 64 is fixed to the front of the side plate 1. The first nut 62 is cylindrical and has internal threads. The first nut 62 is fixed to the bottom of the support frame 64. The first hand wheel 63 is fixed to the front end of the first screw rod 61. The rear end of the first screw rod 61 is provided with the first rotating wheel 65, which is installed in the first T-shaped groove 43 at the front end of the wedge block 4. The first screw rod 61 is threadedly connected to the first nut 62. Rotating the first hand wheel 63 rotates the first screw rod 61, which in turn moves the wedge block 4 forward and backward along the inclined sliding groove and the sliding groove 51.
[0051] The second linear moving device 7 includes a second screw 71, a second nut 72, a second handwheel 73, a mounting plate 74, and a second rotating wheel 75. The mounting plate 74 is fixed to the left side of the side plate 1. The second nut 72 is cylindrical with internal threads and is fixed to the mounting plate 74. The second handwheel 73 is fixed to the left end of the second screw 71. The right end of the second screw 71 has a second rotating wheel 75, which is installed in the second T-slot 73 at the left end of the lower slide block 5. The second screw 71 and the second nut 72 are threadedly connected. Rotating the second handwheel 73 causes the second screw 71 to rotate, thereby driving the lower slide block 5 to move left and right, and driving the front end (operating side) of the guide pinch roller 8 to move left and right, that is, to reciprocate linearly along the running direction of the steel belt.
[0052] The first linear motion device 6 and the second linear motion device 7 are arranged perpendicularly, and the second handwheel 73 is arranged at a 90° angle to the first handwheel 63.
[0053] like Figures 5-7 As shown, a method for correcting the deviation of a guide pinch roller, based on the above-mentioned device, specifically includes the following steps:
[0054] 1. Figure 5 The images, in order, show the state of the bearing housing on the operating side (right side) of the guide pinch roller before height adjustment, the state with the bearing housing lowered, and the state with the bearing housing raised.
[0055] like Figure 7 As shown, if the left side (drive side) of the guide pinch roller 8 is lower than the right side (operation side), resulting in a height difference, the wedge block 4 is moved to the left by rotating the first handwheel 63 to reduce the height of the right side of the guide pinch roller 8, thereby correcting the height of the guide pinch roller 8.
[0056] 2. For example Figure 7 As shown, if the left side of the guide pinch roller 8 is higher than the right side, resulting in a height difference, the wedge block 4 is moved to the right by rotating the first handwheel 63, thereby raising the height of the right side of the guide pinch roller 8 and correcting the height of the guide pinch roller 8.
[0057] 3. Under normal circumstances, the axis of the guide pinch roller is perpendicular to the running direction of the steel strip, and the included angle between the two should be 90°. Set the axis at this time as the reference line. The reference line passes through the center of the guide pinch roller and is perpendicular to the running direction of the steel strip.
[0058] like Figure 6 As shown, if the front end of the guide pinch roller 8 swings to the right, resulting in a horizontal deviation, and there is an angle between the axis of the guide pinch roller and the baseline, the lower slider 5 is moved to the left by rotating the second handwheel, so that the axis of the guide pinch roller coincides with the baseline, thus achieving horizontal correction.
[0059] 4. For example Figure 6As shown, if the front end of the guide pinch roll 8 swings to the left side, a horizontal difference occurs, and an angle exists between the axis of the guide pinch roll and the reference line. By rotating the second hand wheel 75 to drive the lower sliding block 5 to move to the right side, the axis of the guide pinch roll coincides with the reference line, and the horizontal direction is corrected.
[0060] The present application realizes high-precision lifting adjustment of the operating side bearing seat of the guide pinch roll 8 through the cooperation of the upper inclined block 2, the positioning inclined block 3, the wedge block 4 and the lower sliding block 5, has the significant advantages of fast correction response and high precision, and can efficiently convert horizontal displacement into vertical lifting movement when the wedge block 4 moves along the inclined sliding groove and the sliding groove 51, so that the height of the operating side of the guide pinch roll is quickly adjusted, and the steel strip deviation problem is accurately corrected; the device adopts a modular design of inclined surface sliding cooperation, has compact structure and convenient installation, reduces the complex transmission mechanism of the traditional correction device, and is convenient for installation and maintenance in limited space; the sliding contact surface of the inclined block and the sliding groove 51 is precisely machined, has the characteristics of stable operation and small wear, and is not easy to be stuck for a long time; the lifting amplitude can be accurately controlled by adjusting the displacement of the wedge block 4, and the adjustment is flexible and has strong adaptability, which can meet the correction needs of steel strips of different specifications; and the present application provides an efficient and reliable steel strip correction solution for a cold rolling continuous annealing unit.
[0061] The present application realizes accurate and controllable mechanical operation of the displacement adjustment of the wedge block 4 by additionally arranging the first linear movement device 6 composed of the first screw rod 61 and the first nut 62. The rotation movement is converted into linear displacement through the threaded pair, which not only significantly improves the precision and stability of the correction operation, but also effectively avoids the drift phenomenon that may occur in the traditional hydraulic system through the mechanical self-locking characteristic; the screw transmission mechanism has a torque amplification effect, and the operator only needs to exert a small torque to realize the large thrust movement of the wedge block 4, which not only reduces the manual adjustment strength, but also ensures the impact resistance in the high-speed running working condition of the steel strip; the structure adopts a standardized threaded component, and the wearing parts can be directly replaced during maintenance, which reduces the maintenance cost compared with a complex servo system, while the reliability advantage of pure mechanical transmission is reserved, and the structure is particularly suitable for long-term stable work in the harsh environment of a rolling mill workshop with much dust and high vibration.
[0062] The cooperation of the first T-shaped groove 43 and the first rotating wheel 65 is equivalent to the shaft sleeve movement pair in the sliding bearing, and the rotating wheel freely rotates in the T-shaped groove while avoiding axial movement. Compared with the rolling bearing, the present application does not need to be maintained, and the service life and reliability are improved. Similarly, the second T-shaped groove 52 and the second rotating wheel 75 have the same effect.
[0063] The present application rotates the first screw rod 61 by the first hand wheel 65, and realizes significant improvement in operation convenience and labor saving through the humanized design of arranging the first hand wheel 65 at the end of the first screw rod 65. Similarly, the second hand wheel 75 and the second screw rod 71 have the same effect.
[0064] Normally, the axis of the guide pinch roll is perpendicular to the running direction of the steel strip, and the included angle between the two should be 90°. The axis at this time is set as the reference line, which passes through the center of the guide pinch roll and is perpendicular to the running direction of the steel strip. After the guide pinch roll is deflected, the axis of the guide pinch roll and the reference line form an included angle. By rotating the second linear moving device 7 to drive the lower sliding block to move along the running direction of the steel strip, the guide pinch roll is adjusted to make the axis of the guide pinch roll coincide with the reference line, so that the horizontal direction deviation is corrected. In cooperation with the original lifting adjusting mechanism, the guide pinch roll has the vertical lifting and horizontal swing angle adjusting capabilities. The compound deviation correction mode of "lifting + swing angle" can effectively compensate the three-dimensional deviation of the steel strip.
[0065] The second screw 71 is arranged at the end of the second hand wheel 73, which is 90° away from the first hand wheel 63 in space. The operator can complete the three-dimensional adjustment at the same station.
[0066] The present application is installed on the operating side of the swing arm frame, occupies small space, has simple and compact structure, is easy to operate, does not need large cost investment, so that the real-time deviation correction of the steel strip is realized. The present application avoids the winding disorder (such as tower-shaped winding, loose winding), the scratch of the edge of the steel strip, and is beneficial to improve the production efficiency and product quality.
[0067] The protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
