[0026] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0027] The bearing seat on the operating side of the middle roll of the eighteen-roll single frame is composed of two parts, one is the radial bearing seat, and the other is the thrust bearing seat. The two bearing seats are connected by two connecting rods and positioned by a copper slider. This structure is to enable large-size roll shifting operations. The opening size between the two bearing seats is generally between 261mm and 262mm. The bearing seat is very easy to move during the lifting process and the process of lifting it to the roll changing car, and the opening size cannot be guaranteed. As a result, after the bearing seat enters the rolling mill, the locking device cannot fix the bearing seat, which leads to roll changing failure.

[0028] Based on the above considerations, an embodiment of the present application proposes a bearing seat gap size adjustment tool, which sets a calibration ruler with a length equivalent to the gap size and uses the calibration ruler to constrain the gap size between the two bearings to reduce the probability of roller replacement failure due to abnormal movement of the bearing seat and improve the stability of roller replacement.

[0029] Reference below Figure 1-Figure 2 A bearing seat opening size adjustment tool according to an embodiment of the present application is described.

[0030] The bearing seat opening size adjustment tool 1 comprises a calibration ruler 2, an adjustment part 3 and a connecting part.

[0031] The calibration ruler 2 extends along a first direction, and the length of the calibration ruler 2 is a preset length.

[0032] In this embodiment, the length direction of the calibration ruler 2 extends along the first direction, and the length of the calibration ruler 2 is a preset length, which is the opening size of the two bearing seats 5. Taking the opening size of 261mm-262mm as an example, the preset length of the calibration ruler 2 can be 261mm±0.5mm.

[0033] The adjusting member 3 is arranged at one side of the calibration ruler 2 , and the two ends of the adjusting member 3 in the first direction are provided with adjusting parts 33 movably arranged along the first direction.

[0034] In this embodiment, the adjusting part 3 can adjust the positions of the two bearing seats 5 during the roller changing process. The adjusting part 3 is arranged on one side of the calibration scale 2 in its radial direction so that the adjusting part 3 does not affect the stop between the calibration scale 2 and the bearing seat 5. Both ends of the adjusting part 3 are provided with adjustment parts 33 that can be movably arranged along the length direction of the calibration scale 2. The adjustment part 33 can be connected to the bearing seat 5 and adjust the relative position of the bearing seat 5 so that the bearing seat 5 and the two ends of the calibration scale 2 stop to ensure the stability of the opening size.

[0035] The connecting piece is connected between the adjusting piece 3 and the calibration ruler 2 .

[0036] In this embodiment, a connecting piece is provided to connect the adjusting piece 3 and the calibration ruler 2 so that the adjusting piece 3 and the calibration ruler 2 are connected as a whole, so as to facilitate the use and storage of the adjustment tool.

[0037] In actual implementation, when the roller bearing seats 5 are assembled, the calibration ruler 2 is placed at the opening position of the two bearing seats 5, and the relative positions of the two bearing seats 5 are adjusted by adjusting parts so that the two bearing seats 5 are stopped against the two ends of the calibration ruler 2, ensuring that the opening size of the two bearing seats 5 is the preset length of the calibration ruler 2, thereby realizing the adjustment of the opening size.

[0038] According to the bearing seat opening size adjustment tool 1 provided in the embodiment of the present application, by setting the calibration ruler 2 and the adjustment member 3, during the roller changing process, the calibration ruler 2 is supported between the two bearing seats 5, and the two bearing seats 5 are kept against the calibration ruler 2 through the adjustment part 33 on the adjustment member 3, so that the distance between the two bearing seats 5 is kept stable, reducing the probability of roller changing failure due to abnormal movement of the bearing seats 5, and improving the stability of roller changing.

[0039] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the adjusting member 3 may include a driving portion 31 and two adjusting rods 32 .

[0040] The driving part 31 can be connected to the side of the calibration ruler 2 through a connecting piece; both adjustment rods 32 can be dynamically coupled to the driving part 31, the adjustment rods 32 extend along a first direction, the driving part 31 is used to drive the adjustment rods 32 to move along the first direction, and an adjustment part 33 is provided at one end of the adjustment rod 32 away from the driving part 31.

[0041] In this embodiment, the adjustment rod 32 is arranged to extend along the first direction so that the adjustment portion 33 on the adjustment rod 32 contacts the bearing seat 5, and the two adjustment rods 32 are driven to move along the first direction by the driving portion 31 to drive the adjustment portion 33 to move, thereby driving the bearing seat 5 to move. It can be understood that the movement directions of the two adjustment rods 32 are arranged in opposite directions, and the adjustment portions 33 on the two adjustment rods 32 are respectively connected to the two bearing seats 5 located on both sides of the calibration scale 2 in the first direction.

[0042] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the adjusting portion 33 may include a stop plate, which may be connected to an end of the adjusting rod 32 away from the driving portion 31 and may extend along the lateral direction of the adjusting rod 32 .

[0043] In this embodiment, the adjustment portion 33 can be a stop plate. By setting the stop plate to extend laterally along the adjustment rod 32, when the stop plate contacts the bearing seat 5, the contact area between the stop plate and the bearing seat 5 is increased, the force area of ​​the bearing seat 5 is increased, and the position of the bearing seat 5 is adjusted conveniently.

[0044] In some embodiments, the adjustment portion 33 may be a claw that can be cooperatively connected with the bearing seat 5, and the claw is cooperatively connected with the bearing seat 5 to drive the bearing seat 5 to move when the adjustment rod 32 moves.

[0045] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, one end of the stop plate can be connected to the end of the adjustment rod 32 away from the driving part 31, and the other end can extend in a direction close to the calibration ruler 2.

[0046] When assembling the bearing seat 5, the opening size may be larger than the preset size due to the movement of the bearing seat 5. When using the adjustment tool, the calibration ruler 2 can be set between the two bearing seats 5. At this time, the adjustment member 3 is located on one side of the two bearing seats 5, and the adjustment member 3 is located on the upper side of the bearing seat 5. Because the other end of the stop plate extends in a direction close to the calibration ruler 2, the stop plate extends downward to facilitate contact with the bearing seat 5.

[0047] In actual implementation, the driving part 31 drives the adjusting rod 32 to extend in a direction away from the driving part 31, so that the stop plate is located on the side of the bearing seat 5 away from the calibration scale 2, and the calibration scale 2 is placed in the opening position of the two bearing seats 5. The driving part 31 then drives the adjusting rod 32 to extend in a direction close to the driving part 31, so that the stop plate and the side wall of the bearing seat 5 away from the calibration scale 2 are stopped, and the two bearing seats 5 are pushed to move in a direction close to each other until they stop with the calibration scale 2, thereby realizing the adjustment of the opening size. The operation is simple and the effect is good.

[0048] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the dimension of the driving part 31 in the first direction can be smaller than the length of the calibration ruler 2 , and when the two adjustment parts 33 move to one end close to the driving part 31 , the distance between the two adjustment parts 33 can be smaller than the length of the calibration ruler 2 .

[0049] When assembling the bearing seat 5 , the movement of the bearing seat 5 may cause the opening size to be smaller than the preset size, thereby causing the calibration ruler 2 to be unable to be placed in the opening position of the two bearing seats 5 .

[0050] In this embodiment, by setting the dimension of the driving part 31 in the first direction to be smaller than the length of the calibration scale 2, and the minimum spacing between the two adjustment parts 33 to be smaller than the length of the calibration scale 2, when the driving part 31 drives the two adjustment parts 33 to move to a position close to the driving part 31, the adjustment member 3 and the adjustment part 33 can be placed in the open position of the two bearing seats 5.

[0051] In actual implementation, when the gap size of the two bearing seats 5 is smaller than the length of the calibration ruler 2, the two adjustment parts 33 are driven by the driving part 31 to move in the direction of approaching each other until the spacing between the two adjustment parts 33 is smaller than the gap size of the two bearing seats 5 at present, and the adjustment part 3 is placed in the gap position of the two bearing seats 5, and the two adjustment parts 33 are driven by the driving part 31 to move in the direction away from each other, so that the adjustment parts 33 push the two bearing seats 5 to move in the direction away from each other until the gap size of the two bearing seats 5 is larger than the length of the calibration ruler 2, and then the adjustment tool is reversed to place the calibration ruler 2 in the gap position of the two bearing seats 5, and then the execution method of the aforementioned embodiment is used to drive the two bearing seats 5 to stop with the calibration ruler 2 to achieve the adjustment of the gap size of the two bearing seats 5.

It can be understood that when the hydraulic cylinder drives the hydraulic rods to move, the two hydraulic rods move relative to each other in the opposite direction. The two adjustment rods 32 are respectively fixedly connected to the free ends of the two hydraulic rods, thereby realizing that the hydraulic cylinder drives the two adjustment rods 32 to move.

[0054] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, one end of the adjustment rod 32 away from the adjustment portion 33 may be provided with a threaded structure, the free end of the hydraulic rod may be provided with a threaded structure, and the adjustment rod 32 may be threadedly connected to the hydraulic rod.

Exemplarily, the adjustment rod 32 can include a long adjustment rod 32 and a short adjustment rod 32. When the opening size of the bearing seat 5 is greater than the length of the calibration ruler 2, the long adjustment rod 32 is connected to the hydraulic rod so that the adjustment part 33 can be set on the side of the bearing seat 5 away from the calibration ruler 2, thereby driving the two bearing seats 5 to approach each other; when the opening size of the bearing seat 5 is less than the length of the calibration ruler 2, the short adjustment rod 32 is connected to the hydraulic rod so that the two adjustment parts 33 can be placed in the opening position of the two bearing seats 5 when they move to the minimum spacing. When the two bearing seats 5 are pushed away from each other until the opening size is greater than the length of the calibration ruler 2, the long adjustment rod 32 is replaced to be connected to the hydraulic rod, and the above method is repeated.

[0058] In some embodiments, the driving part 31 can also be a gear box structure, a driving gear is provided on the inner side of the driving part 31, and a rack structure is provided on the side of the adjusting rod 32. The adjusting rod 32 extends into the gear box and the rack cooperates with the driving gear. The driving gear is rotated to drive the adjusting rod 32 to move in the first direction.
