Description

TECHNICAL FIELD

[0001] The utility model relates to cold rolling mill roller adjusting technical field, specifically to a kind of high-precision roll gap adjusting device of ultra-thin silicon steel strip cold rolling mill. BACKGROUND

[0002] In the production process of ultra-thin silicon steel strip, cold rolling mill plays a vital role. Cold rolling mill is pressed to the strip by roll to achieve the required thickness and performance. However, the precise control of roll gap is one of the key factors to ensure the uniformity of strip thickness and quality. Most of the traditional roll gap adjusting methods use manual adjustment or coarse automatic adjustment mechanism. These traditional methods can meet the production requirements to a certain extent, but when faced with ultra-thin silicon steel strip, which requires high precision, its limitations are revealed. Manual adjustment method depends on the experience and touch of the operator, and it is difficult to ensure the accuracy and consistency of each adjustment, which affects the uniformity of strip thickness. While the coarse automatic adjustment mechanism can automatically adjust the roll gap, its adjustment precision is limited, and it often cannot meet the high precision requirements of ultra-thin silicon steel strip on roll gap. Therefore, in the actual production process, the problem of strip thickness out-of-tolerance caused by roll gap deviation occurs from time to time, which not only reduces the product pass rate, but also increases the production cost and waste. SUMMARY

[0003] (I) Utility model purposes

[0005] (II) Technical solutions

[0006] A high-precision roll gap adjusting device for ultra-thin silicon steel strip cold rolling mill, comprising a support table, the support table is provided with a sliding groove on both sides, and two groups of bearing seats are movably installed in the sliding groove, a roll is arranged between the two groups of bearing seats, a gap adjusting mechanism is arranged on both sides of the support table, and a precision track is fixedly installed on the outer surface of both sides of the support table, and the two groups of bearing seats are movably installed on the outer surface of the precision track.

[0007] Preferably, the gap adjusting mechanism comprises two groups of fixed seats, which are fixedly installed on the upper and lower sides of both ends of the support table, a circular through slot is formed in the outer surface of the two groups of fixed seats, and a bidirectional screw rod is movably installed in the circular through slot, the bidirectional screw rod penetrates the outer surface of the bearing seat, and one end of the bidirectional screw rod is connected with a motor, and the motor is fixedly connected with the fixed seat.

[0008] Preferably, a controller is arranged on one side of the top end of the support table.

[0009] Preferably, a position sensor is provided on one outer surface of each of the two sets of bearing housings.

[0010] Preferably, the bottom end of the support platform is connected to a support base, and the outer surface of the support base has multiple sets of mounting screw holes.

[0011] Preferably, a reinforcing plate is fixedly installed between the support platform and the support base.

[0012] Preferably, a reinforcing block is fixedly installed at the bottom end of both sets of fixing seats.

[0013] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0014] This invention utilizes a motor in the start-up gap adjustment mechanism. The motor's rotational power is transmitted to a bidirectional lead screw, causing it to rotate stably within a circular groove. The thread design of the bidirectional lead screw, in conjunction with the bearing housing, ensures linear movement of the bearing housing and the roll during adjustment. This not only improves the accuracy of adjustment but also guarantees the stability of the roll during adjustment.

[0015] This invention utilizes a position sensor and a controller. The position sensor monitors the actual size of the roll gap in real time and feeds the data back to the controller. The controller, as the intelligent core of the entire adjustment system, compares and analyzes the preset roll gap parameters with the actual data fed back by the position sensor. Once a deviation is detected between the actual gap and the preset parameters, the controller immediately and automatically adjusts the motor's speed and rotation direction, driving the bidirectional lead screw for fine-tuning. This real-time monitoring and intelligent control method not only improves the accuracy and efficiency of adjustment but also reduces errors caused by human operation. Attached Figure Description

[0022] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0023] Please see Figures 1-5 One embodiment provided by this utility model:

[0024] A high-precision roll gap adjustment device for an ultra-thin silicon steel strip cold rolling mill includes a support platform 1. Slide grooves are opened on both sides of the support platform 1, and two sets of bearing seats 7 are movably installed in each slide groove. A roll 2 is arranged between the two sets of bearing seats 7. A gap adjustment mechanism is provided on both sides of the support platform 1, and a precision track 8 is fixedly installed on the outer surface of both sides of the support platform 1. The two sets of bearing seats 7 are movably installed on the outer surface of the precision track 8.

[0025] Furthermore, the gap adjustment mechanism includes two sets of fixed seats 6, which are fixedly installed on the upper and lower sides of both ends of the support platform 1. The outer surfaces of the two sets of fixed seats 6 are provided with circular through grooves, and a bidirectional lead screw 9 is movably installed in the circular through grooves. The bidirectional lead screw 9 passes through the outer surface of the bearing seat 7, and one end of the bidirectional lead screw 9 is connected to a motor 911. The bidirectional lead screw 9 enables the two sets of bearing seats 7 to move simultaneously and synchronously in opposite or the same direction, thereby achieving precise adjustment of the roll gap. The motor 911 is fixedly connected to the fixed seats 6, maintaining the stability of the motor 911.

[0026] Furthermore, a controller 913 is installed on one side of the top of the support platform 1. Controller 913 serves as the intelligent core of the entire adjustment system, responsible for receiving feedback data from the position sensor 912 and performing real-time analysis and adjustment based on preset parameters. By setting up the controller, automated and intelligent control of the gap between the rolls 2 can be achieved, improving the accuracy and efficiency of the adjustment.

[0027] Furthermore, position sensors 912 are provided on one outer surface of the two sets of bearing housings 7. The position sensors 912 can monitor the changes in the gap between the rolls 2 in real time and feed the data back to the controller 913, which helps to detect and correct deviations in the adjustment process in a timely manner and ensure that the gap between the rolls 2 is always kept within the preset accurate range.

[0028] Furthermore, the bottom of the support platform 1 is connected to a support base 3, and the outer surface of the support base 3 is provided with multiple sets of mounting screw holes 4. The multiple sets of mounting screw holes 4 can easily fix the device on the ground or other support structures, thereby improving the stability and safety of the device.

[0029] Furthermore, a reinforcing plate 5 is fixedly installed between the support platform 1 and the support base 3. The reinforcing plate 5 is used to enhance the connection strength between the support platform 1 and the support base 3 and improve their stability.

[0030] Furthermore, a reinforcing block 914 is fixedly installed at the bottom of the two sets of fixing seats 6. The reinforcing block 914 enhances the stability of the fixing seat 6 and prevents the fixing seat 6 from loosening or deforming due to excessive force during the adjustment process.

[0031] Working Principle: When the gap between the rolls 2 needs to be adjusted to meet the cold rolling requirements of ultra-thin silicon steel strip, the motor 911 in the gap adjustment mechanism is first activated. The rotational power of the motor 911 is transmitted to the bidirectional lead screw 9 through the transmission system, causing the bidirectional lead screw 9 to rotate within the circular groove. Due to the threaded design of the bidirectional lead screw 9, when the lead screw rotates, the two sets of bearing seats 7 that are threadedly engaged with it will move linearly along the precision track 8. This design ensures the stability and accuracy of the bearing seats 7 and the rolls 2 during the adjustment process. As the bearing seats 7 move, the gap between the two sets of rolls 2 will gradually change. To monitor this change in real time, a position sensor 912 is installed on one outer surface of the bearing seat 7. The position sensor 912 can accurately measure the actual size of the gap between the rolls 2 and feed this data back to the controller 913. As the intelligent core of the entire adjustment system, the controller 913 can compare and analyze the preset roll gap parameters with the actual data fed back by the position sensor 912. Once a deviation between the actual gap and the preset parameters is detected, the controller will automatically adjust the speed and direction of rotation of the motor 911, thereby driving the bidirectional lead screw 9 to make fine adjustments until the gap between the rolls 2 reaches the preset precise value.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
