Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, and in particular to a rolling mill. Background Technology

[0002] A rolling mill is a mechanical device used to process steel billets into various steel products. The surface of the rolls is usually specially treated to improve their wear resistance and corrosion resistance. During the rolling process, the steel billet passes through the gap between the rolls and is subjected to the pressure and friction of the rolls, thereby being processed into the required shape and size. Guide devices are usually provided to allow the steel billet to move between multiple rolling mills.

[0003] In traditional rolling mill guiding devices, the shape and size of the guide rollers are designed according to the specifications and shape of the rolled steel products to ensure accurate guidance of the steel's movement between mills. Supports, typically welded from steel, are structural components that support the guide rollers. The design of these supports must ensure sufficient strength and stability to withstand the various forces exerted during the rolling process.

[0004] However, the guide rollers in a rolling mill are often directly connected to the mill stand. During the rolling process, the temperature of the guide rollers continuously rises due to contact with high-temperature steel and frictional heat generation. Excessive temperature affects the mechanical properties and service life of the guide rollers. Guide rollers are prone to wear after prolonged contact with high-temperature steel. Since guide rollers are not easy to disassemble, it is difficult to inspect and replace worn parts, which leads to a decrease in guiding accuracy and affects the quality of steel and production efficiency.

Multiple guide rollers are rotatably connected to the support platform. Each guide roller has a quick-release device at its end. The quick-release device includes a connecting platform, a rotating wheel, a turntable, and multiple sliders. One end of the connecting platform is rotatably connected to the end of the guide roller. A turntable-shaped through groove and multiple guide grooves are formed inside the connecting platform. The turntable is installed in the turntable-shaped through groove. Multiple sliders are slidably connected inside the turntable. Each slider is guided by a corresponding guide groove and slides into the corresponding guide groove. The turntable and the connecting platform are engaged. Each slider is fixedly connected to a sliding shaft, the other end of which protrudes from the side of the turntable and is slidably connected to a rotating wheel. The rotating wheel is rotatably connected to the support platform.

[0020] See appendix Figure 1-4 This embodiment describes a rolling mill, including a support platform 1, multiple guide rollers 2, a quick-release device, and a cooling device. Multiple guide rollers 2 are rotatably connected to the support platform 1. Each guide roller 2 has a quick-release device at its end. Each quick-release device includes a connecting platform 3, a rotating wheel 5, a turntable 7, and multiple sliders 8. One end of the connecting platform 3 is rotatably connected to the end of the guide roller 2. The connecting platform 3 has a turntable-shaped through groove 21 and multiple guide grooves 10 inside. The turntable 7 is installed in the turntable-shaped through groove 21. Multiple sliders 8 are slidably connected inside the turntable 7. Each slider 8 is guided by a corresponding guide groove 10. The turntable 7 engages with the connecting platform 3 by sliding the slider 8 into the corresponding guide groove 10. Each slider 8 is fixedly connected to a sliding shaft 9. The other end of the sliding shaft 9 protrudes from the side of the turntable 7 and is slidably connected to the rotating wheel 5. The rotating wheel 5 is rotatably connected to the support platform 1. The cooling device is located above the support platform 1 and includes a lead screw 16, a slide rail 13, a water tank 11, and multiple spray pipes 12. Both ends of the slide rail 13 are fixedly connected to the support platform 1. A slide table 18 is provided on the slide rail 13. The water tank 11 is fixedly connected to the slide table 18. Multiple spray pipes 12 are fixedly connected to the bottom of the water tank 11. The lead screw 16 is located above the slide rail 13. Multiple connecting shafts 19 are fixedly connected to the slide table 18. The other ends of the multiple connecting shafts 19 are slidably connected to the guide groove of the lead screw 16. Specifically, the support platform 1 is made of stainless steel.

[0021] This invention uses an electric motor 4 to drive the rotating wheel 5 to rotate, which in turn pushes the sliding shaft 9 to move, allowing the slider 8 to slide along the inside of the guide groove 10. When the slider 8 is completely retracted into the turntable 7, the engagement between the turntable 7 and the connecting platform 3 is released, allowing the guide roller 2 connected to the connecting platform 3 to be quickly disassembled. This structure enables convenient disassembly of the guide roller 2, facilitating the inspection and replacement of worn parts, ensuring guiding accuracy, steel quality, and production efficiency. This invention also uses a motor 15 to drive the lead screw 16 to rotate, which in turn moves the sliding platform 18 to repeatedly spray the steel with water from the water tank 11 and the spray pipe 12. During the rolling process, the guide roller 2's temperature continuously rises due to contact with the high-temperature steel and frictional heat generation. Excessive temperature can affect the mechanical properties and service life of the guide roller 2. This structure sprays coolant onto the surface of the guide roller 2 to quickly reduce its temperature and prevent damage from overheating.

[0022] An electric motor 4 is fixedly connected inside the support platform 1, and the electric motor 4 is belt-driven to the rotating wheel 5. The electric motor 4 drives the rotating wheel 5 to rotate, thereby controlling the extension and retraction of the slider 8 at the turntable 7, and realizing the disassembly of the guide roller 2.

[0023] Multiple arc-shaped grooves 6 are formed on the rotating wheel 5, and each sliding shaft 9 is slidably connected in the corresponding arc-shaped groove 6. Through the arc-shaped grooves 6, the circumferential motion of the rotating wheel 5 can be converted into the linear motion of the slider 8, thereby realizing the slider 8 sliding along the guide groove 10.

[0024] The turntable 7 has multiple T-shaped grooves 22, and each slider 8 and its sliding shaft 9 are slidably connected in the corresponding T-shaped groove 22. Specifically, when the slider 8 extends out of the groove, the guide roller 2 is connected to the support table 1. When the slider 8 moves completely into the groove, the guide roller 2 is disengaged from the support table 1 and is in a disassembled state.

[0025] The ends of the slide rail 13 are all fixedly connected to the mounting base 17, and the ends of the lead screw 16 are all rotatably connected to the mounting base 17. The lead screw is positioned above the slide rail 13 by the mounting base 17, so that when the lead screw rotates, it drives the slide table 18 to move along the slide rail 13.

[0026] A pulley 20 is provided between the slide table 18 and the slide rail 13. The pulley 20 reduces the friction between the slide table 18 and the slide rail 13, preventing the slide table 18 from wearing down the slide rail 13 during long-term use.

[0027] The support platform 1 has a support platform 14 on its side wall, and a motor 15 is fixedly connected to the support platform 14.

[0028] The output end of the motor 15 is fixedly connected to one end of the lead screw 16. The motor 15 drives the lead screw 16 to rotate, and the lead screw 16 drives the water tank 11 to move on the slide rail 13, so that the water tank 11 sprays coolant onto the surface of the guide roller 2, which quickly reduces the temperature of the guide roller 2 and prevents it from being damaged due to overheating.

[0029] The water tank 11 is filled with coolant.

[0030] The following describes the specific working steps of a steel rolling mill according to this utility model: When the guide roller 2 needs to be disassembled or replaced for maintenance, the electric motor 4 is started. The electric motor 4 drives the rotating wheel 5 to rotate. At this time, multiple arc-shaped grooves 6 inside the rotating wheel 5 push the sliding shaft 9 to slide inside the arc-shaped grooves 6. As the sliding shaft 9 moves, it pushes the slider 8 out of the guide groove 10. When the multiple sliders 8 are completely retracted into the T-shaped groove 22, the locking relationship between the turntable 7 and the connecting table 3 is released, allowing the guide roller 2 on the side wall of the connecting table 3 to be disassembled. This structure enables convenient disassembly of the guide roller 2, allowing for inspection and replacement of worn parts, ensuring guiding accuracy, steel quality, and production efficiency. When it is necessary to cool the steel during the guiding process, the motor 4 is started. Motor 15 drives lead screw 16 to rotate inside the fixed platform. As lead screw 16 rotates, it pushes connecting shaft 19 through a guide groove inside, causing connecting shaft 19 to slide inside lead screw 16. Under force, connecting shaft 19 pushes slide table 18 at its bottom, causing slide table 18 to repeatedly move within slide rail 13. During this process, pulley 20 rotates inside slide table 18 to ensure stable movement. The movement of slide table 18, in turn, drives water tank 11 and spray pipe 12 at its bottom to repeatedly spray the steel. During the rolling process, the temperature of guide roller 2 continuously rises due to contact with high-temperature steel and frictional heat generation. Excessive temperature can affect the mechanical properties and service life of guide roller 2. Therefore, this structure sprays coolant onto the surface of guide roller 2 to quickly reduce its temperature and prevent damage due to overheating.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
