Description

Technical Field

[0001] This utility model relates to the field of bar rolling technology, and in particular to a bar rolling looper height adjustment device. Background Technology

[0002] In the bar rolling process, the looper is a key device for controlling the tension of the rolled piece and ensuring the stability of the rolling rhythm. Its core function is to adjust the height of the looper so that the rolled piece forms a stable arc-shaped loop between adjacent rolling mills, thereby absorbing speed differences and preventing steel piling or breakage.

[0003] Traditional loopers typically use bolts to rigidly lock the looper rolls and looper arms. When the rolled workpiece becomes entangled or jammed inside the looper, operators need to disassemble multiple sets of fixing bolts in a confined space. Furthermore, the high temperature of the looper roll surface poses a risk of burns. Bolts are also prone to seizing in high-temperature environments, causing oxide scale to adhere to the threads. Disassembly requires destructive cutting, further exacerbating equipment wear. Therefore, we propose a looper height adjustment device for bar rolling. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a bar rolling looper height adjustment device. This device can solve the problems that traditional loopers are mostly rigidly locked with bolts between the looper roller and the looper arm. When the rolled workpiece is wrapped or jammed in the looper, the operator needs to disassemble multiple sets of fixing bolts in a narrow space. In addition, the surface of the looper roller is hot, which can easily cause burns. The bolts are prone to seizing in the high temperature environment, which causes oxide scale to cause thread adhesion. Disassembly requires destructive cutting, which further aggravates equipment wear.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bar rolling looper height adjustment device, comprising: A passageway is provided on one side of the bridge. The replacement structure is located on the bridge. The replacement structure includes a rotating column, a connecting plate, a loose mounting base, a rotating roller, four fixed plates, a sliding rod, a bidirectional threaded rod, and a stepper motor. The rotating column is rotatably connected inside the bridge, with both ends of the rotating column extending rotatably to the outside of the bridge. The connecting plate is fixedly connected to one end of the rotating column, and the loose mounting base is fixedly connected to one side of the connecting plate. The rotating roller is rotatably connected inside the loose mounting base, and the four fixed plates are all fixedly connected to the side of the loose mounting base away from the bridge. The sliding rod and the bidirectional threaded rod are rotatably connected to the opposite surfaces of two corresponding fixed plates. The stepper motor is fixedly mounted on the corresponding fixed plate, and the output end of the stepper motor rotatably passes through the corresponding fixed plate and is fixedly connected to the bidirectional threaded rod. An annular groove is formed on the outer surface of the rotating roller.

[0006] Preferably, the replacement structure further includes two locking plates. Two sliding blocks are threadedly sleeved on the outer surface of the bidirectional threaded rod, and two identical sliding blocks are slidably sleeved on the outer surface of the slide rod. Both locking plates are fixedly connected to the corresponding two sliding blocks. The opposite surfaces of the two locking plates are slidably connected to the inside of the annular groove. Multiple rotating grooves are opened inside the two locking plates, and rolling columns are rotatably connected inside the multiple rotating grooves.

[0007] Preferably, a mounting plate is fixedly connected to the side of the bridge away from the through channel, and an electric telescopic rod is rotatably connected to the opposite side of the mounting plate and the bridge.

[0008] Preferably, a rotating plate is fixedly sleeved on the outer surface of the rotating column, the rotating plate is located outside the bridge, and the telescopic end of the electric telescopic rod is rotatably connected to the inside of the rotating plate.

[0009] Preferably, all of the rolling columns are in rolling contact with the interior of the annular groove.

[0010] Preferably, the bottom of the bridge is fixedly connected to two support bases.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The bar rolling looper height adjustment device uses a bidirectional threaded rod to drive two locking plates to move in opposite directions and engage with the annular groove of the rotating roller, thus achieving a firm lock on the rotating roller. This avoids the cumbersome operation of disassembling multiple sets of fixing bolts in a narrow space when the workpiece is entangled or jammed, which is a problem with bolt locking. This reduces the labor intensity and safety risks for operators, thereby ensuring the stability of the rolling process and product quality. Attached Figure Description

[0017] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0018] Please see Figure 1-5 This utility model provides a technical solution: a bar rolling looper height adjustment device, comprising: Bridge 1, with a through groove 7 on one side; Replace the structure; the replacement structure is located on bridge 1. The replacement structure includes a rotating column 8, a connecting plate 5, a loose mounting seat 6, a rotating roller 9, four fixed plates 13, a sliding rod 14, a bidirectional threaded rod 15, and a stepper motor 12. The rotating column 8 is rotatably connected inside the bridge 1, and both ends of the rotating column 8 extend rotatably to the outside of the bridge 1. The connecting plate 5 is fixedly connected to one end of the rotating column 8. The loose mounting seat 6 is fixedly connected to one side of the connecting plate 5. The rotating roller 9 is rotatably connected inside the loose mounting seat 6. The four fixed plates 13 are all fixedly connected to the side of the loose mounting seat 6 away from the bridge 1. The sliding rod 14 and the bidirectional threaded rod 15 are rotatably connected to the opposite surfaces of the corresponding two fixed plates 13. The stepper motor 12 is fixedly mounted on the corresponding fixed plate 13. The output end of the stepper motor 12 rotatably passes through the corresponding fixed plate 13 and is fixedly connected to the bidirectional threaded rod 15. An annular groove 11 is formed on the outer surface of the rotating roller 9.

[0019] The replacement structure also includes two locking plates 10. Two sliding blocks 16 are threadedly sleeved on the outer surface of the bidirectional threaded rod 15. Two identical sliding blocks 16 are slidably sleeved on the outer surface of the slide rod 14. Both locking plates 10 are fixedly connected to the corresponding two sliding blocks 16. The opposite surfaces of the two locking plates 10 are slidably connected to the inside of the annular groove 11. Multiple rotating grooves 18 are opened inside the two locking plates 10. Rolling columns 17 are rotatably connected inside the multiple rotating grooves 18.

[0020] A mounting plate 4 is fixedly connected to the side of the bridge 1 away from the through groove 7. An electric telescopic rod 3 is rotatably connected to the opposite side of the mounting plate 4 and the bridge 1. A rotating plate 2 is fixedly sleeved on the outer surface of the rotating column 8. The rotating plate 2 is located outside the bridge 1. The telescopic end of the electric telescopic rod 3 is rotatably connected to the inside of the rotating plate 2. Multiple rolling columns 17 are in rolling contact with the inside of the annular groove 11. Two support bases are fixedly connected to the bottom of the bridge 1.

[0021] Furthermore, when using this device, if it is necessary to adjust the height of the bar rolling looper, the electric telescopic rod 3 is activated. When the electric telescopic rod 3 extends or retracts, it pushes or pulls the rotating plate 2, causing the rotating column 8 to rotate within the bridge 1. The rotation of the rotating column 8 drives the looper mounting seat 6 and the rotating roller 9 to rotate as a whole, thereby achieving the initial adjustment of the looper's height and angle.

[0022] After the looper is adjusted to the appropriate position, the stepper motor 12 is started. The stepper motor 12 drives the bidirectional threaded rod 15 to rotate. The rotation of the bidirectional threaded rod 15 causes the two sliding blocks 16 to move in opposite directions along the bidirectional threaded rod 15 and the slide bar 14 under the action of the corresponding locking plate 10. This, in turn, drives the two locking plates 10 to move. During the movement, the locking plates 10 are engaged in the annular groove 11 to lock and fix the rotating roller 9, preventing the looper from shaking or shifting due to external force during use. At the same time, the rolling columns 17 rotatably connected inside the two locking plates 10 all roll in contact with the inside of the annular groove 11. During the movement and locking of the locking plates 10, the rolling of the rolling columns 17 reduces friction, making the locking operation smoother and avoiding excessive wear on the rotating roller 9 and the locking plates 10.

[0023] The two locking plates 10 are driven to move in opposite directions by the bidirectional threaded rod 15 and are locked into the annular groove 11 of the rotating roller 9, thus achieving a firm lock on the rotating roller 9. This avoids the cumbersome operation of disassembling multiple sets of fixing bolts in a narrow space when the workpiece is entangled or jammed, which is a problem with bolt locking. This reduces the labor intensity and safety risks of the operators, thereby ensuring the stability of the rolling process and the quality of the product.
