Description

Technical Field

[0001] This utility model relates to the field of metal rolling technology, and in particular to a high-precision rolling loop tension adjustment device. Background Technology

[0002] In modern steel rolling production, high-precision rolling technology is crucial for improving steel quality and meeting the demands of high-end manufacturing. The looper, as a key component of the rolling production line, directly affects the uniformity of steel thickness, shape quality, and surface quality. The tension roll, as the core component of the looper tension adjustment device, plays an irreplaceable role throughout the entire rolling process.

[0003] In traditional rolling looper tension adjustment devices, the tension rolls are subjected to friction and alternating stress during rolling, resulting in rapid wear. Once defects such as wear and scratches appear on the surface of the tension rolls, they directly affect the surface quality of the red steel. Furthermore, the installation structure of the tension rolls is complex, usually using bolt connections. When the tension rolls need to be replaced, operators need to spend a lot of time using specialized tools to remove these connecting parts one by one. The process of removing the connecting bolts is cumbersome, inefficient, and greatly prolongs the downtime of the production line, leading to a significant reduction in production efficiency. Therefore, we propose a high-precision rolling looper tension adjustment device. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a high-precision rolling looper tension adjustment device. This device can solve the problem that in traditional rolling looper tension adjustment devices, the tension roller is subjected to friction and alternating stress during the rolling process, and its wear rate is relatively fast. Once the surface of the tension roller has defects such as wear and scratches, it will directly affect the surface quality of the red steel. Moreover, the installation structure of the tension roller is complicated and usually uses bolt connections. When the tension roller needs to be replaced, the operator needs to spend a lot of time using professional tools to remove these connecting parts one by one. The process of removing the connecting bolts is cumbersome, which is not only inefficient, but also greatly prolongs the downtime of the production line, resulting in a significant reduction in production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision rolling looper tension adjustment device, comprising:

[0026] Please see Figure 1-5 This utility model provides a technical solution: a high-precision rolling looper tension adjustment device, comprising:

[0027] Looping table 1, with two vertical roller mechanisms 7 installed on both sides of the looping table 1, and a lifting roller mechanism 4 provided on the looping table 1;

[0028] The lifting roller mechanism 4 includes an electric telescopic rod 9, a connecting arm 10, a rotating roller 8, a lifting roller arm 26, a mounting base 12, and a tension roller 11. The electric telescopic rod 9 is rotatably connected to one side of the looper platform 1. The telescopic end of the electric telescopic rod 9 is rotatably connected to the inside of the connecting arm 10. One end of the rotating roller 8 is fixedly connected to the side of the connecting arm 10 near the looper platform 1. The end of the rotating roller 8 away from the connecting arm 10 rotates through the looper platform 1 and is fixedly connected to the lifting roller arm 26. The lifting roller arm 26 contacts the side of the looper platform 1 away from the electric telescopic rod 9. The mounting base 12 is fixedly connected to the inside of the lifting roller arm 26. A slot 13 is provided on the side of the mounting base 12 away from the lifting roller arm 26. An insert block 21 is slidably connected inside the slot 13. A rotating column 22 is rotatably connected inside the insert block 21. The tension roller 11 is fixedly connected to the end of the rotating column 22 away from the mounting base 12. An adjusting groove 14 is provided inside the mounting base 12.

[0029] The lifting roller mechanism 4 also includes two insert rods 17, a sliding plate 16, a spring 18, and a pull rod 15. The sliding plate 16 is slidably connected inside the adjusting groove 14. The two insert rods 17 are fixedly connected to the bottom of the sliding plate 16. The top of the insert block 21 has two insertion holes 23. The bottom ends of the two insert rods 17 slide into the interior of the slot 13 and are inserted into the corresponding insertion holes 23. The pull rod 15 is fixedly connected to the top of the sliding plate 16. The top end of the pull rod 15 slides to the outside of the adjusting groove 14. The spring 18 is sleeved on the outer surface of the pull rod 15. The top end of the spring 18 is fixedly connected to the interior of the adjusting groove 14, and the bottom end of the spring 18 is fixedly connected to the sliding plate 16.

[0030] Two plug holes 20 are provided on the outer surface of the mounting base 12. Both plug holes 20 are fitted with anti-detachment plugs 19. Both anti-detachment plugs 19 are connected to the top of the pull rod 15 by a connecting strap. Both anti-detachment plugs 19 are made of rubber. The insert block 21 has a limit groove 25 inside. A limit ring 24 is slidably connected inside the limit groove 25. The limit ring 24 is fixedly sleeved on the outer surface of the rotating column 22.

[0031] An outlet guide roller mechanism 2 is installed on one side of the looper table 1, and an inlet guide roller mechanism 6 is installed on the side of the looper table 1 away from the outlet guide roller mechanism 2. Two pressure roller mechanisms 3 and two bottom roller mechanisms 5 are installed inside the looper table 1.

[0032] Furthermore, when replacing the tension roller 11 using this device, first remove the anti-detachment plug 19 from the plug hole 20. The operator first pulls the pull rod 15 upward to overcome the elastic force of the spring 18, causing the sliding plate 16 to move upward in the adjusting groove 14, which drives the insertion rod 17 to be pulled out from the insertion hole 23 of the insertion block 21. After releasing the locking of the insertion rod 17, slide the insertion block 21 horizontally along the slot 13 to separate the tension roller 11 from the mounting base 12. The rotating column 22 and the insertion block 21 achieve circumferential rotation and axial limitation through the limiting ring 24 and the limiting groove 25 to ensure the stability of the roller body during disassembly.

[0033] Insert the insert block 21 of the new tension roller 11 into the slot 13, pull the lever 15, and after the insert block 21 is inserted into the slot 13, release the lever 15. The spring 18 pushes the sliding plate 16 down, so that the insert rod 17 is re-inserted into the insertion hole 23 to complete the locking. Finally, press the anti-loosening plug 19 into the plug hole 20, thereby limiting the lever 15 to prevent it from loosening.

[0034] When the electric telescopic rod 9 extends, it drives the rotating roller 8 to rotate through the connecting arm 10, which in turn drives the lifting roller arm 26 to lift upward, thereby adjusting the tension roller 11. By controlling the stroke of the electric telescopic rod 9, the height of the looper can be precisely adjusted, thereby controlling the tension of the hot steel. During the rolling process, the tension roller 11 rotates freely in the insert block 21 through the rotating column 22 to adapt to the speed changes of the hot steel. The vertical roller mechanism 7, the pressure roller mechanism 3, and the bottom roller mechanism 5 work together to ensure that the hot steel runs smoothly in the looper and reduce tension fluctuations.

[0035] The disassembly and replacement structure of this device, with the insertion block 21 cooperating with the slot 13 and the insertion rod 17 locking with the insertion hole 23, allows operators to quickly disassemble and install the tension roller without using complicated professional tools to tighten bolts. This shortens the time required to replace the tension roller 11, avoids production stoppages caused by frequent tension roller replacements, and further improves production efficiency.
