Abstract
Description
Technical Field
[0001] This utility model relates to the field of rolling mill equipment technology, and in particular to a shaft support bracket and a short stress line rolling mill. Background Technology
[0002] With the development of modern metallurgical technology, short-stress wire rod mills, with their advantages of high rigidity, good precision, light weight, simple operation, and convenient roll changing, have become the most widely used type of mill in bar, wire rod, and section steel production workshops. The transmission structure of this type of mill employs a method where the motor's power is transmitted to the rolls via a gearbox and then through a connecting shaft, thereby driving the rolls to rotate. Within the mill structure, the connecting shaft bracket serves as an auxiliary mechanism, its main function being to balance the weight of the connecting shaft, ensuring that the motor's torque is smoothly transmitted to the rolls under different opening degrees, preventing roll fluctuations caused by shaft instability, and thus ensuring stable rolling.
[0003] In the existing short-stress line rolling mill's shaft support structure, a liner is installed on the side of the support body that fixes the bearing housing. An axial bolt along the universal joint secures the liner to the support body on the side where it contacts the bearing housing. After a period of use, the bolt easily breaks, causing the liner to detach from the support body. Due to structural limitations, replacing the liner requires complete removal of the universal joint and bearing housing, which is cumbersome, time-consuming, and extremely labor-intensive for workers. Under the current point-of-care maintenance management model, the support liner cannot be replaced promptly, increasing the risk of equipment accidents. Furthermore, when the support is worn, it can only be repaired at the factory by welding the transmission, which is very expensive and increases the workshop's spare parts costs.
[0004] Therefore, there is an urgent need for a safe, reliable, and easy-to-replace liner structure. Utility Model Content
[0005] The purpose of this utility model is to provide a shaft support bracket and a short stress line rolling mill. The liner in the shaft support bracket can be adjusted in position, effectively extending the service life. It is also easy to disassemble and assemble, which can effectively improve the replacement efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A shaft bracket includes: a bracket body, a bearing seat, and a liner;
[0008] The bearing housing is mounted on the bracket body. The bracket body has a mounting groove extending along the arrangement direction of the connecting shaft at the connection point with the bearing housing. The mounting groove is through a direction perpendicular to the arrangement direction of the connecting shaft and perpendicular to the axis of the connecting shaft. Two opposite sides of the mounting groove and perpendicular to the axis of the connecting shaft form two mounting surfaces. The connecting end of the bearing housing extends into the mounting groove and connects with the mounting surface.
[0009] The two mounting surfaces are provided with the liner on the side facing the connecting end. The liner includes a pad sandwiched between the mounting surface and the connecting end, and a fixing plate connected to the side of the pad away from the bearing seat. The fixing plate is located outside the mounting groove and extends from the side of the pad toward the side away from the connecting end. The fixing plate is adjustablely connected to the bracket body in a direction perpendicular to the mounting surface.
[0010] In the aforementioned shaft bracket, the connecting end of the bearing housing extends into the mounting groove of the bracket body and connects with the mounting surfaces on both sides of the mounting groove. A liner is provided between the connecting end and the mounting surface. The liner includes a pad and a fixing plate that are fixedly connected to each other. The pad is sandwiched between the connecting end and the mounting surface, which can effectively reduce the wear of the mounting surface and the connecting end. The fixing plate is fixedly connected to the pad. The fixing plate is located on the side of the mounting groove away from the bearing housing. One side of the fixing plate is connected to the side of the pad away from the bearing housing. The fixing plate is located on the outside of the mounting groove and is connected to the bracket body. The fixing plate will avoid the bearing housing. When replacing the liner, the connection between the fixing plate and the bracket body can be directly released on the outside. The pad can then be pulled out from the side of the mounting groove away from the bearing housing without disassembling the shaft and bearing housing. This makes the installation and disassembly of the liner convenient, effectively improves the replacement efficiency of the liner, effectively shortens the equipment maintenance time, improves maintenance efficiency, and also reduces the labor intensity of workers. Furthermore, the fixing plate is adjustablely connected to the bracket body in a direction perpendicular to the mounting surface. In other words, the liner is installed on the bracket body in a direction perpendicular to the mounting surface. When the side of the liner facing the connecting end becomes worn, the position of the liner can be adjusted to move it slightly towards the connecting end before fixing it in place. Relative to the same mounting groove, this means moving the liners on both sides of the connecting end towards the center, clamping the connecting end. Therefore, adjustments can be made after the liner has worn down, effectively ensuring the connecting end is securely clamped, reducing the risk of wear on the mounting surface, and making the bracket body less prone to damage, thus effectively reducing the repair cost of the bracket body. Moreover, the liner can continue to be used after adjustment, extending its service life. It only needs to be replaced when it is accidentally damaged or worn beyond repair, reducing spare parts costs.
[0011] Optionally, the bracket body includes two support frames that are opposite to each other and spaced apart. The two support frames are fixed relative to each other, and the bearing seat is located between the two support frames. Each support frame is provided with the mounting groove. The mounting grooves on the two support frames are opposite to each other, and the bearing seat is provided with the connecting end at both opposite ends.
[0012] Each of the fixing brackets is connected to the support frame body by at least two fastening bolts, the at least two fastening bolts being spaced apart along the extension direction of the mounting groove. The support frame body is provided with a first connecting hole, the axis of the first connecting hole being perpendicular to the arrangement direction of the connecting shaft and perpendicular to the axis of the connecting shaft. The fixing plate is provided with a second connecting hole opposite to the first connecting hole, and the fastening bolts pass through the first connecting hole and the second connecting hole; wherein, at least one of the first connecting hole and the second connecting hole is a strip hole extending along the axis of the connecting shaft.
[0013] Optionally, each of the fixing plates is provided with at least two set screw mechanisms on the side opposite to the connecting end, and the at least two set screw mechanisms are spaced apart along the extension direction of the mounting groove; the set screw mechanism includes: a base located on the side of the fixing plate opposite to the connecting end and fixed to the support frame, and an adjusting bolt, the base is provided with a threaded through hole, the axis of the threaded through hole is perpendicular to the mounting surface, the adjusting bolt cooperates with the threaded through hole, and one end of the adjusting bolt abuts against the surface of the fixing plate on the side opposite to the connecting end;
[0014] The set screw mechanisms located on both sides of the same mounting groove are arranged opposite to each other.
[0015] Optionally, the fastening bolt is a countersunk head hex bolt.
[0016] Optionally, the second connecting hole is a strip-shaped hole extending along the axis of the connecting shaft, and the first connecting hole is a circular hole.
[0017] Optionally, the liner is a nylon sheet.
[0018] Optionally, the mounting groove has an opening on its top side in its extending direction.
[0019] Optionally, the fixing plate is perpendicular to the pad, and the cross-sections of the fixing plate and the pad are "L" shaped.

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0028] refer to Figure 1 and Figure 2As shown, this utility model provides a shaft bracket. For ease of explanation, the arrangement direction of the shafts is taken as the vertical direction. Figure 2 This is a partial cross-sectional view of a shaft connector bracket provided in this embodiment along the horizontal direction. Specifically, the shaft connector bracket of this embodiment includes: a bracket body 1, a bearing seat 2, and a liner 3; wherein, the bearing seat 2 is mounted on the bracket body 1, and the bearing seat 2 has a mounting hole through which the shaft passes. A bushing is provided in the mounting hole, and the shaft mates with the bushing and connects with the mounting hole. The connection between the bracket body 1 and the bearing seat 2 is provided with a mounting groove 11 extending along the arrangement direction of the shaft. The mounting groove 11 is through a direction perpendicular to the arrangement direction of the shaft and perpendicular to the axis of the shaft. Two opposite sides of the mounting groove 11 and perpendicular to the axis of the shaft form two mounting surfaces. The connecting end of the bearing seat 2 extends into the mounting groove 11 and connects with the mounting surface. The connecting end of the bearing seat 2 is the part of the bearing seat that connects with the mounting groove. The two mounting surfaces in the same mounting groove 11 facing the connecting end respectively have The liner 3 is provided, each liner 3 including a pad 31 sandwiched between the mounting surface and the connecting end, and a fixing plate 32 connected to the side of the pad 31 away from the bearing seat 2. The fixing plate 32 is located outside the mounting groove 11 and extends from the side of the pad 31 toward the side away from the connecting end. The fixing bracket is located on the side of the bracket body 1 away from the bearing seat 2, and the fixing plate 32 is adjustablely connected to the bracket body 1 in a direction perpendicular to the mounting surface. The fixing plate 32 and the bracket body 1 are detachably connected. Specifically, the liner 3 is made of nylon sheet material. The material of the liner 3 is nylon (polytetrafluoroethylene), which has high strength, impact resistance, and friction resistance, and can effectively enhance the service life of the liner 3. Both the pad 31 and the fixing plate 32 are made of nylon sheet material, and the top plate and the fixing plate 32 are an integral structure, which has better structural integrity and is more robust.
[0029] In the aforementioned shaft bracket, the connecting end of the bearing housing 2 extends into the mounting groove 11 of the bracket body 1 and connects with the mounting surfaces on both sides of the mounting groove 11. A liner 3 is provided between the connecting end and the mounting surface. The liner 3 includes a pad 31 and a fixing plate 32 that are fixedly connected to each other. The pad 31 is sandwiched between the connecting end and the mounting surface, which can effectively reduce the wear of the mounting surface and the connecting end. The fixing plate 32 is fixedly connected to the pad 31. The fixing plate 32 is located on the side of the mounting groove 11 away from the bearing housing 2, and one side of the fixing plate 32 is connected to the side of the pad 31 away from the bearing housing 2. The fixing plate 32 is located outside the mounting groove 11 and is connected to the bracket body 1. The fixing plate 32 will avoid the bearing seat 2. When replacing the liner 3, the connection between the fixing plate 32 and the bracket body 1 can be directly disconnected on the outside. The pad 31 can then be pulled out from the side of the mounting groove 11 away from the bearing seat 2 without disassembling the connecting shaft and bearing seat 2. This makes the installation and disassembly of the liner 3 convenient, effectively improves the replacement efficiency of the liner 3, can effectively shorten the equipment maintenance time, improve maintenance efficiency, and also reduce the labor intensity of workers. Furthermore, the fixing plate 32 is adjustablely connected to the bracket body 1 in a direction perpendicular to the mounting surface. This means the liner 3 is mounted on the bracket body 1 in a direction perpendicular to the mounting surface. When the side of the pad 31 facing the connecting end is worn down, the position of the liner 3 can be adjusted to move it slightly towards the connecting end before fixing it in place. Relative to the same mounting groove 11, this means moving the liner 3 on both sides of the connecting end towards the center, clamping the connecting end. Therefore, adjustments can be made after the pad 31 is worn down, effectively ensuring the connecting end is firmly clamped, reducing the risk of wear on the mounting surface, and making the bracket body 1 less prone to damage, thus effectively reducing the repair cost of the bracket body 1. Moreover, the liner 3 can continue to be used after adjustment, extending its service life. It only needs to be replaced when it is accidentally damaged or worn beyond repair, reducing spare parts costs.
[0030] In one possible implementation, such as Figure 1 As shown, the bracket body 1 includes two support frames 12 arranged opposite to each other and spaced apart. The two support frames 12 are fixed relative to each other, and the bearing seat 2 is located between the two support frames 12. Each support frame 12 is provided with a mounting groove 11, and the mounting grooves 11 on the two support frames 12 are opposite to each other. Both opposite ends of the bearing seat 2 are provided with connecting ends. Specifically, the support frame 12 can be a support part with a plate-like structure, and the two support parts are arranged opposite to each other. The bearing seat 2 is located between the two support parts, and a mounting groove 11 is provided in the middle of the support part. Each end of the bearing seat 2 has a connecting end, which faces the two support parts respectively and is provided in a one-to-one correspondence with the mounting grooves 11 on the two support parts. The connecting ends extend into the corresponding mounting grooves 11. Figure 1As shown, the fixing plate 32 is perpendicular to the pad 31, and the cross-sections of the fixing plate 32 and the pad 31 are "L" shaped. The pad 31 is sandwiched between the connecting end and the mounting surface, and the fixing plate 32 can be attached to the outer side of the support part away from the bearing seat 2 and fixed to the support part.
[0031] Each support section is also connected to a reinforcing rib plate. There are two reinforcing rib plates, which are distributed along the extension direction of the connecting shaft. The reinforcing rib plates are perpendicular to the support section and can be set on both sides of the support section, so as to improve the structural strength of the support frame.
[0032] In each connecting end of the liner 3 between the mounting surface and the mounting plate, the fixing frame is connected to the support frame 12 by at least two fastening bolts 4. The at least two fastening bolts 4 are spaced apart along the extension direction of the mounting groove 11. The support frame 12 is provided with a first connecting hole, the axis of which is perpendicular to the arrangement direction of the connecting shaft and perpendicular to the axis of the connecting shaft. The fixing plate 32 is provided with a second connecting hole opposite to the first connecting hole. The fastening bolts 4 pass through the first connecting hole and the second connecting hole. A nut is provided at the end of the fastening bolt 4 opposite to the nut, so that the fixing plate 32 and the support frame 12 can be fixedly connected. The connection method is firm and reliable and easy to disassemble. Among them, at least one of the first connecting hole and the second connecting hole is a strip hole extending along the axis of the connecting shaft, which allows the liner 3 to be adjusted along the extension direction of the connecting shaft.
[0033] For example, the second connecting hole is a strip-shaped hole extending along the axis of the connecting shaft, and the first connecting hole is a circular hole. This allows the bolt to remain in place, and the liner 3 can be pushed towards the center of the mounting groove 11 along the extension direction of the connecting shaft to adjust the position of the liner 3. Alternatively, if the first connecting hole is set to a strip-shaped hole extending along the axis of the connecting shaft, and the second connecting hole is set to a circular hole, then the liner 3 and the bolt can be pushed together towards the center of the mounting groove 11 to adjust the position of the liner 3.
[0034] Furthermore, the aforementioned fastening bolts are countersunk hexagonal head bolts, which can save more installation space, avoid the shaft, and make adjustment or replacement of the liner plate after wear more convenient and quicker, and the bolts can be removed directly.
[0035] In one possible implementation, refer to Figure 1 and Figure 2As shown, at least two set screw mechanisms 5 are provided on the side of each fixed plate 32 away from the connecting end, and the at least two set screw mechanisms 5 are spaced apart along the extension direction of the mounting groove 11. Specifically, each set screw mechanism 5 includes: a base 51 located on the side of the fixed plate 32 away from the connecting end and fixed to the support frame 12, and an adjusting bolt 52. The base 51 is provided with a threaded through hole, the axis of the threaded through hole is perpendicular to the mounting surface, the adjusting bolt 52 cooperates with the threaded through hole, and one end of the adjusting bolt 52 abuts against the surface of the side of the fixed plate 32 away from the connecting end. Furthermore, the set screw mechanisms 5 located on both sides of the same mounting groove 11 are arranged opposite to each other, and the two corresponding set screw mechanisms 5 on both sides of the same mounting groove 11 are in the same horizontal direction. Specifically, in the two corresponding set screw mechanisms 5 on both sides of the same mounting groove 11, the two bases 51 are opposite to each other, and the threaded through holes on the two bases 51 are coaxially arranged. When it is necessary to adjust the position of the liner 3, it can be adjusted by... Unlock the fastening bolt 4, first rotate the adjusting bolts 52 on both sides of the connecting end. Adjust the screw-in distance of each adjusting bolt 52 towards the connecting end according to the actual situation and tighten it against the side of the fixing plate 32. The adjusting bolts 52 on both sides can clamp the connecting end and the liner 3 in the middle. The set screw mechanism 5 is set on both sides of the mounting groove 11, which can adjust the position of the liner 3 and the connecting end, and keep the connecting end and the liner 3 fixed. When tightening the fastening bolt 4, it can ensure that the position of the liner 3 and the connecting end does not move, the installation is accurate, and the stability is good. In addition, when replacing the liner 3, remove the fastening bolt 4, rotate the adjusting bolt 52 to loosen it slightly, ensure the gap between the connecting end and the mounting surface, and the liner 3 can be removed. After installing the new liner 3, there is no need to make a big adjustment to the position of the liner 3. A fine adjustment to the position of the liner 3 is enough to install the liner 3 and the connecting end, which effectively improves the replacement efficiency.
[0036] For details, please refer to Figure 1 As shown, the mounting groove 11 has an opening on its top side in its extending direction, so that the liner 3 can be pulled out from the opening at the top of the mounting groove 11 for easy disassembly.
[0037] In the aforementioned shaft bracket, there can be two bearing seats 2, which can be referred to as upper bearing seat 2 and lower bearing seat 2, corresponding to the upper and lower shafts. Each shaft corresponds to one bearing seat 2. The upper bearing seat 2 and lower bearing seat 2 are distributed along the arrangement direction of the shafts. The connecting ends located on the same side of the upper bearing seat 2 and lower bearing seat 2 are installed in the same mounting groove 11, and the liner 3 between the same mounting surface corresponding to the two connecting ends is an integral structure. That is, a liner 3 of sufficient length is set between each mounting surface and the upper and lower connecting ends. Specifically, three fastening bolts are set between the fixing plate of each liner and the support frame. The three fastening bolts are evenly spaced, and four set screw mechanisms are set on one side of each liner to ensure that the liner can be stably abutted.
[0038] It should be noted that the length of the mounting groove in the direction of the shaft arrangement is long enough to install two bearing seats, or even more bearing seats. The length of the mounting groove in the direction of the shaft arrangement can be set according to requirements, and this embodiment is not limited thereto.
[0039] Specifically, in the aforementioned shaft bracket, the support frame also includes other structures that connect to the bearing housing. This allows the bearing housing to be securely installed on the bracket body and enables the bearing housing to be adjusted vertically along the extension direction of the mounting groove, allowing the shaft to adapt to the adjustment of the gap between the two rollers. The other structures on the support frame avoid the mounting groove, providing sufficient clearance to ensure that the installation, removal, and position adjustment of the liner are not affected.
[0040] Based on the same design concept, this embodiment also provides a short stress line rolling mill, including any of the shaft support brackets provided in the above embodiments. In the short stress line rolling mill, the liner of the shaft support bracket can be adjusted in position, effectively extending its service life, and is easy to disassemble and assemble, thus effectively improving replacement efficiency.
[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
