Description

Technical Field

[0001] This utility model relates to the field of 20-roll cold rolling mill technology, and in particular to the end structure of a 20-roll cold rolling mill. Background Technology

[0002] The end structure of a 20-roll cold rolling mill mainly refers to the collection of key components located on both sides of the mill, used to support and adjust the various levels of rolls (including work rolls, intermediate rolls, and support rolls) in the entire rolling system. The design of this part plays a crucial role in ensuring uniform force transmission during rolling and achieving precise thickness control.

[0003] In existing technology, the end structure of some 20-roll cold rolling mills is equipped with dedicated bearing seats at both ends of each roll. These bearing seats provide stable support for the high-speed rotating rolls and are one of the most technically advanced and critical parts of the entire equipment. They directly affect whether high-quality products can be produced efficiently and stably. However, in the end structure of some 20-roll cold rolling mills, the ends of the rolls lack lubrication devices, which causes wear due to friction between the ends of the rolls and the bearing seats. The originally precise fit becomes uneven, resulting in inaccurate rolling force transmission. This, in turn, affects the consistency of strip thickness and surface quality, requiring the replacement of the rolls and causing inconvenience to the overall process. Utility Model Content

One end of the support slide rail has a groove. A pulley is slidably connected inside the groove. An operating door is rotatably connected to the top of the pulley. A conveying assembly is rotatably connected to the top of the operating door. An output pipe is fixedly connected to the output end of the conveying assembly.

The lubricating oil can cover the rotating groove through the through hole to lubricate the rotating shaft and prevent wear on the rotating shaft.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides an end structure of a 20-roll cold rolling mill, comprising a main body 1, a rotating shaft 2 rotatably connected inside the main body 1, an intermediate roller 3 fixedly connected outside the rotating shaft 2, a support slide rail 4 fixedly connected to the bottom of the main body 1, a slide groove 4 having one end of the support slide rail 4, a pulley 5 slidably connected inside the slide groove 4, an operating door 6 rotatably connected to the top of the pulley 5, a conveying assembly rotatably connected to the top of the operating door 6, an output pipe 10 fixedly connected to the output end of the conveying assembly, a connecting pipe 11 fixedly connected to the outside of the output pipe 10, and a hollow ring 12 fixedly connected to the outside of the connecting pipe 11.

[0035] Reference Figures 4 to 6 The conveying assembly includes an oil pump 7, an input pipe 8, and an oil tank 9. The oil pump 7 is externally connected to the outside of the operating door 6. The input end of the oil pump 7 is fixedly connected to one end of the input pipe 8. The output end of the oil pump 7 is fixedly connected to one end of the output pipe 10. One end of the input pipe 8 is fixedly connected to the outside of the oil tank 9. The oil tank 9 is externally fixedly connected to the outside of the operating door 6 and is used to draw lubricating oil from inside the oil tank 9. The hollow ring 12 is detachably connected to the outside of the operating door 6.

[0036] Reference Figure 2 , Figure 7 and Figure 8A storage ring 13 is fixedly connected to the outside of the hollow ring 12. A through hole 14 is provided inside the hollow ring 12, and a rotating groove 15 is provided inside the hollow ring 12 for lubricating the rotating shaft 2. The rotating shaft 2 is rotatably connected to the inner wall of the rotating groove 15 and passes through the storage ring 13 to support its rotation. An output pipe 16 is fixedly connected to the outside of the hollow ring 12, and an output pipe 17 is fixedly connected to the outside of the storage ring 13 for outputting from the hollow ring 12. The lubricating oil inside the storage ring 13 is stored in a temporary storage box 18 embedded outside the operating door 6. One end of the temporary storage box 18 is fixedly connected to an oil pipe 19, which is also fixedly connected to the outside of the oil tank 9 to output the lubricating oil inside the temporary storage box 18. One end of the output pipe 2 16 is fixedly connected to the outside of the temporary storage box 18 and passes through the operating door 6. One end of the output pipe 3 17 is fixedly connected to the outside of the temporary storage box 18 and passes through the operating door 6 to transport the lubricating oil.

[0037] Reference Figure 1 , Figure 2 The bottom of the main body 1 is fixedly connected to a support plate 21. The top of the support plate 21 is provided with a sliding groove 2 for sliding the slider 20. The slider 20 slides on the inner wall of the sliding groove 2. One end of the slider 20 is fixedly connected to the bottom of the operating door 6 for driving the operating door 6 to move.

[0038] Working principle: When the oil pump 7 is started, the lubricating oil in the oil tank 9 is drawn through the input pipe 8 and delivered to the connecting pipe 11 through the output pipe 10. Then, it is delivered to the hollow ring 12 through the connecting pipe 11. The amount of lubricating oil delivered to the hollow ring 12 is more than the amount flowing out from the output pipe 16. The lubricating oil accumulates in the hollow ring 12 until the lubricating oil level exceeds the through hole 14. The lubricating oil flows through the through hole 14 onto the rotating groove 15 and onto the surface of the rotating shaft 2. When the rotating shaft 2 rotates, the lubricating oil lubricates the rotating shaft 2, reducing the wear of the rotating shaft 2 and thus reducing the number of times the rotating shaft 2 needs to be replaced.

[0039] Simultaneously, when the rotating shaft 2 rotates, the lubricating oil on the surface of the rotating shaft 2 will splash. The storage ring 13 blocks this splashed lubricating oil, storing the lubricating oil in the storage ring 13. The lubricating oil in the storage ring 13 flows out through the output pipe 17, and the amount of lubricating oil flowing out is greater than the amount of lubricating oil flowing through the through hole 14, preventing the lubricating oil in the storage ring 13 from flowing out through the hole opened in the storage ring 13, and preventing the lubricating oil from flowing onto the workpiece to be processed, thereby affecting the cleanliness and flatness of the workpiece surface. At the same time, the lubricating oil in the hollow ring 12 and the storage ring 13 flows into the temporary storage box 18 through the output pipe 16 and the output pipe 17, and finally flows into the oil tank 9 through the oil pipe 19, thereby allowing the lubricating oil to circulate.

[0040] When it is necessary to replace the rotating shaft 2 and the intermediate roller 3, push the operating door 6 so that it slides along the slide groove 1 and slide groove 2 through the slider 20 and the pulley 5, thereby opening the operating door 6. At the same time, the rotating shaft 2 is removed from the hollow ring 12 and the storage ring 13. When the operating door 6 slides to one end of the slide groove 1 and can no longer slide, push the operating door 6 on one side of the slider 20 so that the operating door 6 rotates through the pulley 5. At the same time, the slider 20 slides in the slide groove 2, allowing the operating door 6 to rotate smoothly until the slider 20 slides to one end of the slide groove 2 and can no longer slide. The rotating shaft 2 that needs to be replaced is then removed and replaced.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
