Description

Technical Field

[0001] This invention relates to the field of rolling technology, specifically to a rolling apparatus for producing high-strength metal sheets. Background Technology

[0002] High-strength metal sheets are thin metal plates made from high-strength steel, aluminum alloys, titanium alloys, and various high-strength alloys as base materials, processed through melting, rolling, heat treatment, finishing, and straightening. They possess outstanding advantages such as high tensile strength, excellent yield performance, good toughness, fatigue resistance, corrosion resistance, and lightweight structure. They also have good stamping, welding, and bending performance, with a dense and uniform internal structure, high dimensional accuracy, and excellent flatness and surface quality. They can serve stably for a long time under heavy loads, impacts, high and low temperatures, and complex working conditions. They can reduce the self-weight of components while improving the overall structural safety factor and service life. They are widely used in automotive bodies, aerospace, rail transportation, construction machinery, pressure vessels, new energy equipment, and precision machinery, and are a key basic material for achieving lightweight, high-strength, and high-reliability designs in high-end equipment manufacturing.

[0003] Chinese patent CN220942570U discloses a rolling and forming production equipment for metal composite plates, including a water storage tank and a spray pipe fixedly connected to a support frame. The spray pipe is connected to the water storage tank through a third pipe and is used to spray water to cool the plate. A circulation component includes a first recovery section and a second recovery section, which are respectively mounted on the support frame and the machine frame, and are respectively positioned corresponding to the plate. A cooling element is mounted on the water storage tank, and the first and second recovery sections are respectively connected to the cooling element. This achieves water cooling of the plate, recovers water resources, and recycles them after cooling, avoiding resource waste and ensuring cooling effect. While this technical solution can complete the spray cooling and temperature reduction operation in the rolling process of thin metal sheets, the recycling and filtration method of the cooling emulsion is relatively simple. During the rolling process of thin metal sheets, the cooling emulsion is easily mixed with and attached with a large amount of fine iron powder and metal debris. The traditional recycling structure can only achieve simple impurity interception and lacks adsorption of fine iron powder. If the fine iron powder suspended in the emulsion is not filtered and adsorbed, the emulsion containing impurities will be recycled and sprayed again, which will not only easily scratch the surface of the thin metal sheet and aggravate the wear of the rolling rolls, but also easily cause filter screen blockage, seriously affecting the rolling quality and the recycling effect of the emulsion.

[0005] This invention provides a rolling apparatus for producing high-strength metal sheets. It has the following advantages: 1. This high-strength metal sheet production rolling device adopts double-sided spraying from the top and bottom, and the emulsion spraying coverage is uniform, which fully cools and lubricates the rolled metal sheet, reduces surface scratches and thermal deformation defects, and improves the quality of rolled products. The mesh plate at the top of the spray box blocks metal impurities generated during rolling, preventing impurities from mixing in. The emulsion is intercepted, filtered and recycled in a closed loop, reducing emulsion consumption.

[0006] 2. The rolling device for producing high-strength metal sheets uses a filter top plate and magnetic adsorption roller to intercept large particles of impurities and adsorb fine suspended iron powder in the emulsion, thereby improving the cleanliness of the recovered emulsion.

[0007] 3. The rolling device for producing high-strength metal sheets has a positioning groove and a support frame forming a guiding and limiting structure to ensure that the slag is scraped off from the surface of the adsorption roller in a timely manner, thus preventing impurities from covering the roller surface and causing a decrease in magnetic attraction.

[0008] 4. The rolling device for producing high-strength metal sheets adopts a double-layer moving frame for layered cleaning, which distributes the workload of each cleaning operation, avoids the problem of excessive slag load and incomplete cleaning in a single operation, and reduces the residue of impurities.

[0009] 5. In this high-strength metal sheet production rolling device, the cleaning plate rotates in a circular motion with the cleaning frame, which can fully cover and clean the entire bottom surface of the filter top plate. Through the adaptive structure of the sliding shaft and connecting spring, the contact pressure between the cleaning plate and the filter top plate is automatically adjusted to avoid impact and squeezing caused by rigid hard contact, and to prevent the filter top plate from being squeezed and damaged.

[0012] Please see Figures 1-3 This invention provides a rolling apparatus for producing high-strength metal sheets, comprising: The support 1 has a workbench 2 fixedly connected to its middle part, rolling components 4 fixedly connected to both sides of the support 1, and a spraying component 3 fixedly connected to the middle of the top of the support 1. The connecting shell 5 is a semi-cylindrical structure. Both ends of the connecting shell 5 are fixedly connected to the inner side of the bracket 1. Both sides of the connecting shell 5 are provided with connecting grooves 6, and both sides of the connecting grooves 6 are rotatably connected with connecting rollers 7. Example 1, please refer to Figures 4-5 The present invention also includes a spraying component 3. The spraying box 31 is arranged in a rectangular structure. A mesh plate 32 is fixedly connected to the top of the spraying box 31. Spraying pipes 33 are symmetrically arranged on both sides of the spraying box 31. A water pump 38 is fixedly connected to one end of the spraying pipe 33. When the water pumps 38 on both sides of the inner cavity of the spraying box 31 are turned on, the water pumps 38 continuously transport the emulsion stored in the spraying box 31 to the spraying frame 34 through the spraying pipes 33. The inner side of the spray frame 34 is fixedly connected to the end of the spray pipe 33 away from the water pump 38. The two spray frames 34 are arranged symmetrically above and below. The side of the upper spray frame 34 is fixedly connected to the inner side of the bracket 1, and the side of the lower spray frame 34 is fixedly connected to the inner side of the workbench 2. Spray nozzles 35 are evenly arranged on the inner side of the spray frame 34. By using the spray nozzles 35 arranged on the upper and lower spray frames 34 of the metal sheet, the metal sheet in the rolling process is sprayed in all directions to achieve uniform cooling and lubrication, and reduce the scratches on the surface of the sheet and the problem of rolling heat deformation. During the spraying process, the emulsion that falls downwards gathers and is collected and returned through the mesh plate 32 set at the top of the spray box 31, so that the emulsion falls back into the spray box 31. Meanwhile, the screen plate 32 can intercept metal scraps and oxide impurities carried in the spray waste liquid, preventing impurities from adhering to the roller and plate surface with the emulsion backflow. The flow guide frame 36 is designed with a wide upper part and a narrow lower part. The top of the flow guide frame 36 is fixedly connected to the bottom of the screen plate 32. The middle part of the flow guide frame 36 is fixedly connected to the filter mechanism 37. The emulsion after pre-discharge filtration by the screen plate 32 is gathered and guided along the wide upper part and narrow lower part of the flow guide frame 36 and sent into the filter mechanism 37 for purification. The filtered and purified clean emulsion is returned to the spray box 31 to realize the recycling and reuse of the emulsion. Please see Figures 6-7 It also includes a filtration mechanism 37. The side of the filter housing 371 is fixedly connected to the middle of the inner side of the guide frame 36. The bottom of the filter housing 371 is fixedly connected to a filter bottom plate 372, and the top of the filter housing 371 is fixedly connected to a filter top plate 373. The emulsion that is guided and collected by the guide frame 36 flows into the inner cavity of the filter housing 371 after passing through the filter top plate 373 to complete secondary filtration. A drive unit 374 is fixedly connected to the middle of the bottom of the filter base plate 372, and an adsorption frame 375 is rotatably connected to the middle of the top of the filter base plate 372. The middle of the bottom of the adsorption frame 375 is fixedly connected to the output end of the drive unit 374. When the drive unit 374 is activated, the adsorption frame 375 is driven to rotate inside the filter housing 371. The adsorption frame 375 synchronously drives the top adsorption roller 378 to rotate together. The top of the adsorption rack 375 is uniformly provided with adsorption rollers 378. The bottom of the adsorption rollers 378 is fixedly connected to the top of the adsorption rack 375. The adsorption rollers 378 are permanent magnet rollers, which adsorb the fine iron powder suspended in the emulsion onto the roller surface to achieve magnetic adsorption and fine filtration of the emulsion. The filtered and purified emulsion flows out from the filter bottom plate 372 and flows back to the spray box 31 to complete the recycling and reuse. A support frame 379 is fixedly connected to one side of the top of the adsorption frame 375. The bottom of the support frame 379 is fixedly connected to the top of the adsorption frame 375. A cleaning component 376 is rotatably connected to the middle of the bottom of the filter top plate 373. A moving component 377 is fixedly connected to the middle of the bottom of the cleaning component 376. While the adsorption frame 375 is rotating, the moving component 377 and the cleaning component 376 are driven to rotate synchronously through the support frame 379. This allows the cleaning component 376 to contact and rub against the bottom of the filter top plate 373, scraping and cleaning the impurities attached to the lower surface of the filter top plate 373 in real time. This prevents the accumulation of impurities from clogging the filter top plate 373 and ensures smooth flow of the emulsion. Please see Figure 8 It also includes a moving component 377. The output end of the cylinder 3771 is fixedly connected to a support shaft 3775. The bottom of the support shaft 3775 is fixedly connected to a moving frame 3772. When the adsorption roller 378 works for a long time and too many metal impurities are adsorbed and accumulated on its surface, the cylinder 3771 is activated. The output end of the cylinder 3771 drives the moving frame 3772 to perform reciprocating linear motion through the support shaft 3775. The movable frame 3772 has positioning grooves 3774 on both the upper and lower sides. The inner side of the positioning groove 3774 is slidably connected to the side of the support frame 379. The movable frame 3772 achieves guidance and limitation by cooperating with the support frame 379 through the positioning groove 3774, ensuring that the movement is stable and does not deviate. The side of the movable frame 3772 is evenly provided with movable grooves 3773. The inner side of the movable grooves 3773 is slidably connected to the side of the adsorption roller 378. When the movable frame 3772 moves, the movable grooves 3773 on the surface are in contact with the surface of the adsorption roller 378 and slide relative to each other, scraping and pushing the impurities accumulated on the surface of the adsorption roller 378 downwards, thus completing the automatic slag cleaning operation of the adsorption roller 378. By continuously cleaning the surface of the adsorption roller 378, it maintains good magnetic adsorption capacity and avoids the large-area accumulation of impurities that leads to a decrease in adsorption efficiency. At the same time, the moving frame 3772 has a double-layer structure, which scrapes and cleans the adsorption roller 378 in layers, which can disperse the cleaning load of a single cleaning and prevent the problem of incomplete cleaning and residual residue caused by excessive cleaning of impurities at one time. Please see Figure 9 It also includes a cleaning component 376. The top of the rotating block 3761 is rotatably connected to the bottom of the filter top plate 373. The bottom of the rotating block 3761 is fixedly connected to the top of the cylinder 3771. When the adsorption frame 375 rotates on the filter bottom plate 372, it drives the support frame 379 to rotate synchronously. The support frame 379 further drives the moving frame 3772 and the support shaft 3775 to rotate synchronously. The output end of the cylinder 3771 is fixedly connected to the support shaft 3775. At the same time, the cylinder 3771 is fixedly connected to the bottom of the rotating block 3761, which can drive the rotating block 3761 to rotate at the center of the bottom surface of the filter top plate 373. Cleaning racks 3762 are fixedly connected to both sides of the rotating block 3761. A cleaning plate 3763 is slidably connected to the inner side of the cleaning rack 3762. Sliding shafts 3764 are evenly arranged on the side of the cleaning plate 3763. The rotating block 3761 synchronously drives the cleaning racks 3762 on both sides to rotate. The cleaning racks 3762 drive the cleaning plate 3763 to contact and rotate against the bottom surface of the filter top plate 373 through the sliding shafts 3764 arranged on the inner side, continuously scraping off the impurities attached to the filter top plate 373, preventing the filter holes of the filter top plate 373 from being blocked, and ensuring that the emulsion filtration channel is unobstructed. One end of the sliding shaft 3764 is slidably connected to the inner side of the cleaning frame 3762, and the other end of the sliding shaft 3764 is fixedly connected to the cleaning plate 3763. A connecting spring 3765 is sleeved on the sliding shaft 3764. One end of the connecting spring 3765 is fixedly connected to the inner side of the cleaning frame 3762, and the other end of the connecting spring 3765 is fixedly connected to the cleaning plate 3763. When the contact pressure between the cleaning plate 3763 and the filter top plate 373 is too high, the cleaning plate 3763 can slide and retract inside the cleaning frame 3762 through the sliding shaft 3764, while squeezing the connecting spring 3765 sleeved on the sliding shaft 3764 to perform adaptive adjustment and movement to avoid the cleaning plate 3763 pressing against the filter top plate 373 and to prevent the plate surface from deforming due to excessive squeezing pressure. Specific workflow: The rolling components 4 are symmetrically installed on the upper and lower parts of the support 1. The rollers in the rolling components 4 rotate on the support 1 to roll the high-strength metal sheet that passes through. The connecting groove 6 on both sides of the outer shell 5 on the bracket 1 is provided with connecting roller 7. The connecting roller 7 contacts the side of the metal sheet and rotates synchronously. It can scrape off the metal debris and impurities that fall off and adhere during the rolling process of the sheet and let them fall off naturally, so as to prevent metal impurities from adhering and accumulating on the surface of the rolling component 4 and prevent impurities from interfering with the normal rolling work. When the rolled metal sheet passes through the spraying area, the spraying component 3 can uniformly spray lubricating emulsion onto the surface of the metal sheet to achieve lubrication and cooling during the rolling process. Turn on the water pumps 38 on both sides of the inner cavity of the spray box 31. The water pumps 38 continuously transport the emulsion stored in the spray box 31 to the spray frame 34 through the spray pipe 33. Using the nozzles 35 set on the spray racks 34 on the upper and lower sides of the metal sheet, the metal sheet is sprayed in all directions during the rolling process to achieve uniform cooling and lubrication, and reduce the surface scratches and rolling thermal deformation of the sheet. During the spraying process, the emulsion that falls downwards gathers and is collected and returned through the mesh plate 32 set at the top of the spray box 31, so that the emulsion falls back into the spray box 31. Meanwhile, the screen plate 32 can intercept metal scraps and oxide impurities carried in the spray waste liquid, preventing impurities from adhering to the roller and plate surface with the emulsion backflow. The emulsion, after being pre-filtered by the mesh plate 32, is gathered and guided by the upper-wide and lower-narrow guide frame 36 and sent into the filtration mechanism 37 for purification. The filtered and purified clean emulsion is returned to the spray box 31 to realize the recycling and reuse of the emulsion. The emulsion, guided and collected by the guide frame 36, flows into the inner cavity of the filter housing 371 after completing secondary filtration through the filter top plate 373. Start the drive unit 374, which drives the adsorption frame 375 to rotate inside the filter housing 371. The adsorption frame 375 synchronously drives the top adsorption roller 378 to rotate together. The adsorption roller 378 is a permanent magnet roller that adsorbs the fine iron powder suspended in the emulsion onto the roller surface, thereby achieving magnetic adsorption and fine filtration of the emulsion. The filtered and purified emulsion flows out from the filter bottom plate 372 and returns to the spray box 31 to complete the recycling and reuse. While the adsorption rack 375 is rotating, the support rack 379 drives the moving component 377 and the cleaning component 376 to rotate synchronously, so that the cleaning component 376 contacts and rotates in contact with the bottom of the filter top plate 373, scraping and cleaning the impurities attached to the lower surface of the filter top plate 373 in real time, avoiding the accumulation of impurities and causing the filter top plate 373 to be blocked, and ensuring the smooth flow of emulsion. When the adsorption roller 378 works for a long time and too many metal impurities accumulate on its surface, the cylinder 3771 is activated. The output end of the cylinder 3771 drives the moving frame 3772 to perform reciprocating linear motion through the support shaft 3775. The movable frame 3772 cooperates with the support frame 379 through the positioning groove 3774 to achieve guidance and limit, ensuring that the movement process is stable and does not deviate. When the moving frame 3772 moves, the moving groove 3773 on its surface slides relative to the surface of the adsorption roller 378, scraping and pushing the impurities accumulated on the surface of the adsorption roller 378 downwards, thus completing the automatic slag removal operation of the adsorption roller 378. By continuously cleaning the surface of the adsorption roller 378, it maintains good magnetic adsorption capacity and avoids the large-area accumulation of impurities that leads to a decrease in adsorption efficiency. At the same time, the moving frame 3772 has a double-layer structure, which scrapes and cleans the adsorption roller 378 in layers, which can disperse the cleaning load of a single cleaning and prevent the problem of incomplete cleaning and residual residue caused by excessive cleaning of impurities at one time. When the adsorption frame 375 rotates on the filter base plate 372, it drives the support frame 379 to rotate synchronously. The support frame 379 further drives the movable frame 3772 to rotate synchronously with the support shaft 3775. The output end of the cylinder 3771 is fixedly connected to the support shaft 3775. At the same time, the cylinder 3771 is fixedly connected to the bottom of the rotating block 3761, which can drive the rotating block 3761 to rotate at the center of the bottom surface of the filter top plate 373. The rotating block 3761 synchronously drives the cleaning racks 3762 on both sides to rotate. The cleaning racks 3762, through the sliding shaft 3764 set on the inner side, drive the cleaning plate 3763 to contact and rotate against the bottom surface of the filter top plate 373, continuously scraping off the impurities attached to the filter top plate 373, preventing the filter holes of the filter top plate 373 from being blocked, and ensuring that the emulsion filtration channel is unobstructed. When the contact pressure between the cleaning plate 3763 and the filter top plate 373 is too high, the cleaning plate 3763 can slide and retract inside the cleaning frame 3762 through the sliding shaft 3764, while squeezing the connecting spring 3765 sleeved on the sliding shaft 3764 to make adaptive adjustment and movement to avoid the cleaning plate 3763 pressing against the filter top plate 373, and to prevent the plate surface from deforming due to excessive squeezing pressure.
