Description

Technical Field

[0001] This utility model relates to the field of cold rolling mill technology, specifically to a spray cooling device for a cold rolling mill. Background Technology

[0002] Cold rolling mills are critical equipment in sheet metal processing. During the rolling process, they generate a large amount of heat, causing a rapid rise in the temperature of the rolls and strip. If cooling is not timely and effective, it will not only affect the service life of the rolls but also lead to a series of quality problems such as uneven strip microstructure, surface oxidation, and poor strip shape, directly impacting the final product's yield and performance. Therefore, spray cooling devices are an indispensable and crucial component of cold rolling mill units.

[0003] A cooling spray device for a cold rolling mill, disclosed in CN218532341U, rotates a spray beam frame inside a U-shaped frame, causing multiple nozzles to rotate. This allows for easy control of the angle at which the nozzles spray rolling oil onto the sheet metal, as well as the distance between the nozzle spraying end and the rolls of the cold rolling mill. This ensures lubrication at the sheet metal pressing points and controls the amount of rolling oil used.

[0004] The cooling spray device of this cold rolling mill rotates the spray beam inside the U-shaped frame, causing multiple nozzles to rotate. This allows for easy control of the angle at which the nozzles spray rolling oil onto the sheet. However, this device cannot adjust the distance between the nozzles and the cold-rolled sheet, making it unsuitable for strips of different thicknesses or with different cooling process requirements. For thin strips or special alloy strips, a spray distance that is too close may lead to over-cooling or strip deformation, while a distance that is too far may lead to insufficient cooling. This lack of process flexibility necessitates improvement. Utility Model Content

[0005] The purpose of this invention is to provide a spray cooling device for a cold rolling mill to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spray cooling device for a cold rolling mill, comprising a base, a fixed platform fixedly connected to the top of the base, a transmission mechanism provided on the outer side of the top of the fixed platform, a spraying mechanism provided in the middle of the top of the fixed platform, and a cold-rolled plate provided on the inner side of the transmission mechanism;

[0007] The spraying mechanism includes a fixed frame, which is fixedly connected to the top center of a fixed platform. A first hydraulic cylinder is fixedly connected to the top of the fixed frame, and a lifting plate is fixedly connected to the bottom of the first hydraulic cylinder. Limit rods are fixedly connected to the front and rear sides of the lifting plate. A spraying plate is fixedly connected to the bottom of the lifting plate. A transmission pipe is fixedly connected to the top center of the spraying plate. A material box is fixedly connected to the bottom of the transmission pipe. A support plate is fixedly connected to the top left side of the material box. A water pump is fixedly connected to the periphery of the transmission pipe and is fixedly connected to the left side of the material box. A water level pipe is fixedly connected to the right side of the material box. A filter plate is slidably connected inside the material box. A sealing plate is fixedly connected to the back end of the filter plate. A bolt is threadedly connected to the inner side of the sealing plate and is threaded into the inside of the material box.

[0008] Preferably, the inner side of the fixed frame is provided with a sliding groove corresponding to the movement trajectory of the limiting rod, and the limiting rod is slidably connected inside the sliding groove. Through the sliding groove, the limiting rod can slide inside the fixed frame, making the lifting plate more stable during the lifting process.

[0009] Preferably, the inner side of the material box is provided with a limiting groove corresponding to the movement trajectory of the filter plate, and the filter plate is slidably connected to the inside of the limiting groove. The limiting groove allows the filter plate to slide inside the material box, making it easy for workers to disassemble and replace the filter plate. The filter plate can filter the cooling oil, making the transmission pipe less prone to clogging.

[0010] Preferably, the transmission tube is disposed inside the support plate, and the outer periphery of the transmission tube is in close contact with the inner side of the support plate. The support plate can support the transmission tube, making the transmission tube more stable during use.

[0011] Preferably, the transmission mechanism includes a connecting frame, which is fixedly connected to the left and right sides of the top of the fixed platform. A second hydraulic cylinder is fixedly connected to the top of the connecting frame, and a U-shaped plate is fixedly connected to the bottom of the second hydraulic cylinder. A guide rod is fixedly connected to the top of the U-shaped plate, and a pressing roller is rotatably connected to the inner side of the U-shaped plate. A second servo motor is fixedly connected to the front of the pressing roller, and a first servo motor is fixedly connected to the front of the connecting frame. A rotating roller is fixedly connected to the back of the first servo motor, and the rotating roller is rotatably connected to the inner side of the connecting frame.

[0012] Preferably, there are two guide rods, which are fixedly connected to the front and rear sides of the top of the U-shaped plate, and are slidably connected to the inner side of the connecting frame. The guide rods can limit the movement of the U-shaped plate, making the U-shaped plate more stable during the lifting and lowering process.

[0013] Preferably, the cold-rolled sheet is disposed at the bottom of the pressing roller and the top of the rotating roller, with the top of the cold-rolled sheet in contact with the bottom of the pressing roller and the bottom of the cold-rolled sheet in contact with the top of the rotating roller. The cold-rolled sheet can be transported by the cooperation of the pressing roller and the rotating roller.

[0014] Compared with the prior art, the present invention provides a spray cooling device for a cold rolling mill, which has the following beneficial effects:

[0015] 1. The spray cooling device of this cold rolling mill has a spray mechanism in which the first hydraulic cylinder can drive the lifting plate to flexibly adjust the height of the spray plate. Combined with the guiding effect of the fixed frame slide groove on the limit rod, this ensures stable lifting and lowering of the spray plate. It can precisely control the spray distance according to the thickness of the cold-rolled plate after processing and the cooling requirements, improving the targeting of cooling. The transmission pipe and water pump work together to transport the cooling medium, ensuring continuous spraying and meeting the cooling needs under different working conditions. The filter plate in the material box can filter the cooling medium, effectively intercepting impurities and preventing blockage of the transmission pipe and spray plate, ensuring stable operation of the spray system. The filter plate is detachably connected by a sealing plate and bolts, and can be disassembled by sliding along the limit groove of the material box, facilitating regular cleaning or replacement by staff, reducing maintenance costs, and extending the overall service life of the device.

[0016] 2. In the spray cooling device and transmission mechanism of the cold rolling mill, the second hydraulic cylinder drives the U-shaped plate to lift and lower the pressing roller. Together with the rotating roller, it can stably clamp and transmit cold-rolled plates of different thicknesses. The guide rod further ensures that the U-shaped plate lifts and lowers smoothly, avoiding the cold-rolled plate from shifting during transmission. Stable transmission allows the surface of the cold-rolled plate to receive spray cooling evenly, reducing the problem of uneven cooling caused by unstable transmission. At the same time, it ensures the flatness of the cold-rolled plate during the rolling process and improves product quality. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please see Figure 1-5 This utility model provides a technical solution: a spray cooling device for a cold rolling mill, including a base 1, a fixed platform 2 fixedly connected to the top of the base 1, a transmission mechanism 3 arranged on the outer side of the top of the fixed platform 2, a spraying mechanism 4 arranged in the middle of the top of the fixed platform 2, and a cold rolling plate 5 arranged on the inner side of the transmission mechanism 3.

[0029] The spraying mechanism 4 includes a fixed frame 41, which is fixedly connected to the top center of the fixed platform 2. A first hydraulic cylinder 42 is fixedly connected to the top of the fixed frame 41. A lifting plate 44 is fixedly connected to the bottom of the first hydraulic cylinder 42. Limit rods 402 are fixedly connected to the front and rear sides of the lifting plate 44. A spraying plate 45 is fixedly connected to the bottom of the lifting plate 44. A transmission pipe 43 is fixedly connected to the top center of the spraying plate 45. A material box 46 is fixedly connected to the bottom of the transmission pipe 43. A support plate 401 is fixedly connected to the top left side of the material box 46. A water pump 403 is fixedly connected to the periphery of the transmission pipe 43. The water pump 403 is fixedly connected to the left side of the material box 46. A water level pipe 47 is fixedly connected to the right side of the material box 46. A filter plate 404 is slidably connected inside the material box 46. A sealing plate 49 is fixedly connected to the back end of the filter plate 404. A bolt 48 is threadedly connected to the inner side of the sealing plate 49. The bolt 48 is threadedly connected to the inside of the material box 46.

[0030] Furthermore, a groove corresponding to the movement trajectory of the limiting rod 402 is provided on the inner side of the fixed frame 41, and the limiting rod 402 is slidably connected inside the groove. Through the groove, the limiting rod 402 can slide inside the fixed frame 41, making the lifting plate 44 more stable during the lifting process.

Through the limiting groove, the filter plate 404 can slide inside the material box 46, making it easy for the staff to disassemble and replace the filter plate 404.

[0032] Furthermore, the transmission pipe 43 is disposed inside the support plate 401, and the outer periphery of the transmission pipe 43 is in close contact with the inner side of the support plate 401. The support plate 401 can support the transmission pipe 43, making the transmission pipe 43 more stable during use.

[0033] Example 2

[0034] Please see Figure 1-5 Furthermore, based on Embodiment 1, the transmission mechanism 3 further includes a connecting frame 33, which is fixedly connected to the top left and right sides of the fixed platform 2. A second hydraulic cylinder 35 is fixedly connected to the top of the connecting frame 33, a U-shaped plate 36 is fixedly connected to the bottom of the second hydraulic cylinder 35, a guide rod 34 is fixedly connected to the top of the U-shaped plate 36, a pressing roller 37 is rotatably connected to the inner side of the U-shaped plate 36, a second servo motor 32 is fixedly connected to the front of the pressing roller 37, a first servo motor 31 is fixedly connected to the front of the connecting frame 33, a rotating roller 38 is fixedly connected to the back of the first servo motor 31, and the rotating roller 38 is rotatably connected to the inner side of the connecting frame 33.

[0035] Furthermore, there are two guide rods 34. The two guide rods 34 are fixedly connected to the front and rear sides of the top of the U-shaped plate 36, and the two guide rods 34 are slidably connected to the inner side of the connecting frame 33. The guide rods 34 can limit the movement of the U-shaped plate 36, making the U-shaped plate 36 more stable during the lifting process.

[0036] Furthermore, the cold-rolled plate 5 is disposed at the bottom of the pressing roller 37 and the top of the rotating roller 38, with the top of the cold-rolled plate 5 in contact with the bottom of the pressing roller 37 and the bottom of the cold-rolled plate 5 in contact with the top of the rotating roller 38. By using the pressing roller 37 and the rotating roller 38 together, the cold-rolled plate 5 can be transported.

[0037] In actual operation, when this device is used, if it is necessary to cool the cold-rolled sheet 5 processed by the cold rolling mill, and the height of the pressing roller 37 needs to be adjusted according to the thickness of the cold-rolled sheet 5, the second hydraulic cylinder 35 switch is turned on, causing the second hydraulic cylinder 35 to drive the U-shaped plate 36 to move upward, so that the U-shaped plate 36 can drive the pressing roller 37 and the second servo motor 32 to move upward, placing the cold-rolled sheet 5 to be cooled on the top of the rotating roller 38. The second hydraulic cylinder 35 switch is turned on again, causing the second hydraulic cylinder 35 to push the U-shaped plate 36, the pressing roller 37 and the second servo motor 32 to move downward, so that the bottom of the pressing roller 37 can contact the top surface of the cold-rolled sheet 5. At the same time, the first servo motor 31 and the second servo motor 32 switch are turned on, causing the second servo motor 32 to drive the pressing roller 37 to rotate, and the first servo motor 31 to drive the rotating roller 38 to rotate, so that the pressing roller 37 and the rotating roller 38 can transport the cold-rolled sheet 5.

[0038] When the height of the spray plate 45 needs to be adjusted according to the thickness of the cold-rolled sheet 5, the first hydraulic cylinder 42 switch is turned on, so that the first hydraulic cylinder 42 pushes the lifting plate 44 and the spray plate 45 to move downward, so that the spray plate 45 drives the transmission pipe 43 to move. When the spray plate 45 moves to the appropriate height, the water pump 403 switch is turned on, so that the water pump 403 works in conjunction with the transmission pipe 43 to transfer the cooling oil inside the material box 46 to the inside of the spray plate 45 through the transmission pipe 43. The cooling oil is then sprayed out through the spray plate 45, so that the cooling oil is sprayed onto the top of the cold-rolled sheet 5 to cool the cold-rolled sheet 5.

[0039] When the cooling oil inside the material tank 46 is used up, pour the cooling oil back into the material tank 46. The poured cooling oil is filtered through the filter plate 404, so that impurities in the cooling oil are less likely to clog the transmission pipe 43. When the filter plate 404 is clogged, the operator uses an external tool to turn the bolt 48 away from the inside of the material tank 46, so that the operator can pull the sealing plate 49 to move the filter plate 404, so that the filter plate 404 can be moved out of the material tank 46 for easy cleaning and replacement.

[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
