Technical Field
[0001] This utility model relates to the field of rolling mill equipment, and more specifically, to a multi-size coil rolling mill. Background Technology
[0002] In the field of rolling mill equipment technology, rolling mills are mainly used to process rolled parts, causing plastic deformation of the rolled parts. They are equipment for realizing the metal rolling process. The rolled parts pass between two rotating work rolls, and the rotating work rolls apply forming pressure to the rolled parts, thereby realizing the rolling process.
[0003] Existing multi-size coil rolling mills typically spray emulsion onto the surface of the coil to reduce friction between the coil and the mill and to cool the coil during rolling. However, current spraying methods usually involve installing multiple nozzles along the length of a transversely arranged pipe to spray the emulsion onto the surface of the coil or sheet. To ensure coverage, a large number of nozzles are usually installed. However, nozzles are vulnerable parts, with a high rate of clogging, wear, and leakage. Replacing, cleaning, and adjusting a large number of nozzles is an extremely tedious and time-consuming task, resulting in high equipment maintenance costs, reduced operating rates, and undoubtedly increased procurement costs. Therefore, we propose a multi-size coil rolling mill... Utility Model Content

[0030] Example 1
[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 A multi-size coil rolling mill includes a base plate 1. Two mounting brackets 2 are fixedly connected to the upper surface of the base plate 1. A support roller 3 and a work roller 4 are arranged between the two mounting brackets 2. A horizontal plate 5 is fixedly connected between the two mounting brackets 2. The interior of the horizontal plate 5 is hollow. A through groove 6 communicating with the interior of the horizontal plate 5 is opened on the front surface of the horizontal plate 5. An atomizing nozzle 7 is arranged inside the through groove 6. A rotating shaft 8 is fixedly connected to the surface of the atomizing nozzle 7. The rotating shaft 8 is rotatably connected to the bottom wall of the internal cavity of the horizontal plate 5. A guide groove 9 is opened inside the horizontal plate 5. A drive assembly is arranged inside the guide groove 9. A supply assembly is arranged on the upper surface of the horizontal plate 5. A protective assembly is arranged on the surface of the horizontal plate 5.
[0032] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the supply assembly includes a storage tank 10, the interior of which is used to store emulsion. A pump body 11 is fixedly connected to the exterior of the storage tank 10. A first connecting pipe 12 is fixedly connected to the output end of the pump body 11. A second connecting pipe 13 is fixedly connected to the surface of the atomizing nozzle 7. The second connecting pipe 13 is connected to the atomizing nozzle 7. The upper end of the second connecting pipe 13 rotatably extends through the upper surface of the horizontal plate 5. A rotating flange 14 is provided between the second connecting pipe 13 and the first connecting pipe 12. By starting the pump body 11 through an external controller, the emulsion inside the storage tank 10 can be introduced from the interior of the first connecting pipe 12 into the interior of the second connecting pipe 13, thereby achieving the purpose of spraying the emulsion from the interior of the atomizing nozzle 7.
[0033] Example 2
[0034] The multi-size coil rolling mill provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the drive assembly includes a reciprocating lead screw 15, which is rotatably connected inside the guide groove 9. A reciprocating lead screw sleeve 16 is fitted around the reciprocating lead screw 15 and slidably connected inside the guide groove 9. The reciprocating lead screw sleeve 16 cooperates with the helical groove on the surface of the reciprocating lead screw 15 through the internal guide element, so that the reciprocating lead screw sleeve 16 can reciprocate along the axial direction of the reciprocating lead screw 15 when the reciprocating lead screw 15 rotates. A motor 27 is fixedly connected to the surface of the right mounting bracket 2. The output shaft of the motor 27 rotates through the interior of the horizontal plate 5 and is fixedly connected to the reciprocating lead screw 15 through a coupling and an extension rod. The motor 27 is started by an external controller. The rotation of the output shaft of the motor 27 drives the reciprocating lead screw 15 to rotate, and the rotation of the reciprocating lead screw 15 drives the movement of the reciprocating lead screw sleeve 16.
[0035] Among them, the motor 27 is also equipped with a power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail in this article.
[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, a toothed plate 17 is slidably connected inside the horizontal plate 5. The toothed plate 17 is fixedly connected to the reciprocating screw sleeve 16. A gear 18 is fixedly sleeved on the outside of the rotating shaft 8. The gear 18 is meshed with the toothed plate 17. The movement of the reciprocating screw sleeve 16 can drive the movement of the toothed plate 17. The movement of the toothed plate 17 can drive the transmission of the gear 18. At this time, the reciprocating movement of the toothed plate 17 can drive the reciprocating rotation of the gear 18. The rotation of the gear 18 can drive the rotation of the rotating shaft 8. The rotation of the rotating shaft 8 can drive the atomizing nozzle 7 to swing, ultimately achieving the purpose of swinging and spraying emulsion on the surface of the roll material.
[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the protective component includes a slide rail 19, which is fixedly connected to the front surface of the horizontal plate 5. Two protective covers 20 are slidably connected to the surface of the slide rail 19. The atomizing nozzle 7 can be protected when idle by closing the two protective covers 20.
[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the protective cover 20 has a groove 21 inside, and an L-shaped sliding plate 22 is slidably connected inside the groove 21. The L-shaped sliding plate 22 slides through the interior of the protective cover 20. The slide rail 19 has a slot 23 on its surface. The slot 23 and the L-shaped sliding plate 22 are adapted to each other. The L-shaped sliding plate 22 can be disengaged from or engaged in the slot 23 by sliding inside the groove 21. When the two L-shaped sliding plates 22 are engaged in the two slots 23 in the middle, the stability of the two protective covers 20 when closed can be guaranteed. When the two L-shaped sliding plates 22 are engaged in the slots 23 on both sides, the protective cover 20 can be prevented from interfering with the atomizing nozzle 7, and the stability of the protective cover 20 can also be guaranteed.
[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, a limiting rod 24 is fixedly connected inside the groove 21, and an L-shaped sliding plate 22 is slidably sleeved on the outside of the limiting rod 24. A compression spring 25 is movably sleeved on the outside of the limiting rod 24. One end of the compression spring 25 is fixedly connected to the inner wall of the groove 21, and the other end of the compression spring 25 is fixedly connected to the L-shaped sliding plate 22. When the L-shaped sliding plate 22 slides inside the groove 21, the compression spring 25 will deform. When the L-shaped sliding plate 22 is no longer under force, the elastic force of the compression spring 25 will make the L-shaped sliding plate 22 firmly stuck into the slot 23, effectively preventing the L-shaped sliding plate 22 from falling out of the slot 23.
[0040] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, hydraulic cylinders 26 are fixedly connected to the upper surfaces of the two mounting frames 2. The telescopic ends of the hydraulic cylinders 26 slide through the interior of the mounting frame 2. The two hydraulic cylinders 26 are fixedly connected to both sides of the working roller 4. The height of the working roller 4 can be adjusted by starting the hydraulic cylinders 26 through an external controller, thereby adjusting the gap between the working roller 4 and the support roller 3. This makes it easier for the operator to adjust the two rollers according to the thickness of the roll material, improving the applicability and flexibility of the device.
[0041] The multi-size coil rolling mill provided by this utility model is used as follows:
[0042] The height of the working roller 4 can be adjusted by starting the hydraulic cylinder 26 through an external controller, thereby adjusting the gap between the working roller 4 and the support roller 3. This allows the operator to adjust the two rollers according to the thickness of the roll material. Subsequently, the motor 27 is started by the external controller. The rotation of the output shaft of the motor 27 drives the reciprocating screw 15 to rotate. The rotation of the reciprocating screw 15 drives the reciprocating screw sleeve 16 to move. The movement of the reciprocating screw sleeve 16 drives the toothed plate 17 to move. The movement of the toothed plate 17 drives the transmission of the gear 18. At this time, the reciprocating movement of the toothed plate 17 drives the reciprocating rotation of the gear 18. The rotation of the gear 18 drives the rotation of the rotating shaft 8. The rotation of the rotating shaft 8 drives the atomizing nozzle 7 to swing. At the same time, the operator can start the pump body 11 through the external controller to introduce the emulsion inside the storage tank 10 from the inside of the first connecting pipe 12 into the inside of the second connecting pipe 13, thereby achieving the purpose of spraying the emulsion from the inside of the atomizing nozzle 7, and finally achieving the purpose of oscillating spraying of emulsion on the surface of the roll material.
[0043] The L-shaped sliding plate 22 can be disengaged from or engaged with the slot 23 by sliding it inside the groove 21. When the two L-shaped sliding plates 22 are engaged with the two middle slots 23, the stability of the two protective covers 20 when closed can be guaranteed, thereby protecting the atomizing nozzle 7 in the idle state. When the two L-shaped sliding plates 22 are engaged with the slots 23 on both sides, the protective cover 20 can be prevented from interfering with the atomizing nozzle 7, and the stability of the protective cover 20 can also be guaranteed.
