Technical Field
[0001] The present invention relates to the technical field of aluminum alloy plate casting and rolling, and particularly relates to a casting and rolling device for aluminum alloy plates. Background Art
[0002] As disclosed in a Chinese patent with the publication number CN118492289A, a twin-roll casting and rolling device for the clean production and deep processing of aluminum alloys is disclosed. A liquid pump is used to transport a coolant from a coolant water tank to a hose, and then through the hose to a water-cooling pipe. The telescopic end of an electric push rod drives the water-cooling pipe to move back and forth through a linkage rod. The coolant is transported from the water-cooling pipe to a liquid guide pipe and then output from the liquid guide pipe and flows back to the coolant water tank, thereby realizing the reciprocating circulation use of the coolant. The thin wall of the aluminum liquid pipeline enables the aluminum liquid to be quickly cooled, and the back-and-forth movement of the water-cooling pipe can accelerate the solidification and curing process of the aluminum liquid, thereby improving production efficiency and reducing the production cycle.
[0003] However, in the casting and rolling device in the above application, condensing the aluminum alloy liquid at the nozzle position will cause the nozzle channel to become narrow or even blocked, hindering the normal outflow of the aluminum alloy liquid, making the flow rate unstable, resulting in uneven distribution in the casting and rolling area, affecting the forming of the aluminum alloy plate, and causing defects such as uneven surface and uneven internal structure of the aluminum alloy plate, making it difficult to ensure continuous and stable casting and rolling production, resulting in problems such as uneven thickness of the aluminum alloy plate and breakage of the strip, and further affecting production efficiency and product quality.

[0007] Further improvement lies in that the liquid cooling component includes two spiral cooling tubes with a spiral structure and installed staggeredly inside the casting and rolling roll. Communication pipes for connecting the two ends of the two spiral cooling tubes are respectively opened on the front and rear sides inside the casting and rolling roll. Liquid inlet holes extending into the communication pipes are respectively opened on the roller shafts at the front and rear ends of the casting and rolling roll. A liquid inlet pipe and a liquid outlet pipe are respectively installed in the front and rear two liquid inlet holes through bearings, and the end of the liquid outlet pipe is connected to the liquid inlet interface of the serpentine heat exchange tube.

[0011] Further improvement lies in that limiting sliding grooves are respectively opened inside both sides of the strip-shaped groove, and sliders installed on both sides of the bearing seat are slidably connected up and down inside the limiting sliding grooves.
[0012] Further improvement lies in that the anti-sticking mechanism includes air delivery boxes installed on both the upper and lower sides of the machine frame, a plurality of flamethrowers facing the casting and rolling roll are arrayed on the air delivery boxes, laser rangefinders for the lateral casting and rolling roll are installed on both the upper and lower sides of the machine frame, grinding rolls are rotatably connected on both the upper and lower sides of the machine frame and below the side of the casting and rolling roll, belt pulleys are installed at the front ends of the roller shafts of the grinding rolls, a transmission belt is connected inside the two belt pulleys, a stepping motor for driving the bottom belt pulley to rotate is installed on the machine frame, and a slag scraping component for scraping the aluminum slag adhered to the casting and rolling roll is provided on the machine frame.

[0018] 4. In the present invention, the liquefied gas is transported into the torch through the gas delivery box and sprayed on the surface of the casting and rolling roll to form a carbon deposit layer, thereby protecting the casting and rolling roll and preventing the casting and rolling roll from sticking aluminum. The laser rangefinder is used to detect the thickness of the carbon deposit layer, which is convenient for carbon supplementation of the locally too thin carbon deposit layer. The rotating grinding roll is used to thin the thicker carbon deposit layer to ensure that the thickness of the carbon deposit layer is consistent. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0039] Embodiment 1
[0040] Based on the problem that the existing technology condenses the aluminum alloy liquid at the nozzle position, resulting in the narrowing or even blockage of the nozzle channel and affecting the forming of the aluminum alloy plate, this embodiment provides a casting and rolling device for aluminum alloy plates. Please refer to Figures 1-9 , this embodiment provides a casting and rolling device for aluminum alloy plates, which can pre-cool the aluminum alloy liquid at the nozzle position and cooperate with the casting and rolling rolls for forming, avoiding blocking the nozzle while improving production efficiency. The casting and rolling device for aluminum alloy plates includes two casting and rolling rolls 2 symmetrically installed up and down between the frames 1. One side of the casting and rolling roll 2 is installed with a hopper 3 through a support rod, and the bottom of the hopper 3 is installed with a nozzle 4 extending into the space between the two casting and rolling rolls 2. The bottom of the hopper 3 is installed with a liquid storage tank 5. A casting and rolling mechanism 6 for roll-cooling and forming the aluminum alloy liquid is provided on the casting and rolling roll 2. An anti-sticking mechanism 7 for cleaning the slag on the surface of the casting and rolling roll 2 and keeping the carbon deposit layer flat is provided on the frame 1. The aluminum alloy liquid flowing between the two casting and rolling rolls 2 is quickly cooled and roll-formed into an aluminum alloy plate through the casting and rolling mechanism 6, and the aluminum alloy liquid in the nozzle 4 is pre-cooled to avoid uneven shrinkage of the aluminum alloy plate caused by too rapid cooling of the aluminum alloy liquid at too high a temperature, resulting in defects such as pores and shrinkage porosity inside. The anti-sticking mechanism 7 is used to scrape off the aluminum chips adhered to the casting and rolling roll 2 to avoid the aluminum chips affecting the surface finish of the aluminum alloy plate.
[0041] Since the existing technology condenses the aluminum alloy liquid at the nozzle 4 position, resulting in the narrowing or even blockage of the nozzle 4 channel and affecting the forming of the aluminum alloy plate, and too rapid cooling of the aluminum alloy liquid at too high a temperature will cause uneven shrinkage of the aluminum alloy plate and defects such as pores and shrinkage porosity inside, the device is provided with a casting and rolling mechanism 6. The casting and rolling mechanism 6 includes a liquid cooling component 61 that circulates coolant into the two casting and rolling rolls 2 at the same time. Heat exchange plates 62 are installed on both the upper and lower sides of the nozzle 4. A serpentine heat exchange tube 63 is installed inside the heat exchange plate 62, and the liquid outlet interface of the serpentine heat exchange tube 63 is installed with a return pipe 64 extending into the liquid storage tank 5. A refrigeration component 65 for cooling the returned coolant for recycling is installed in the liquid storage tank 5. Driving components 66 are provided on both of the two casting and rolling rolls 2. A distance adjusting component 67 for driving the upper casting and rolling roll 2 to move up and down to adjust the casting and rolling distance is provided on the frame 1.
[0042] The liquid cooling component 61 includes two spiral cooling tubes 611 with a spiral structure and are staggeredly installed in the casting roll 2. The front and rear sides inside the casting roll 2 are respectively provided with connecting tubes 612 that connect the two ends of the two spiral cooling tubes 611. Liquid inlet holes 613 extending into the connecting tubes 612 are provided on the roller shafts at the front and rear ends of the casting roll 2. A liquid inlet pipe 614 and a liquid outlet pipe 615 are respectively installed in the front and rear two liquid inlet holes 613 through bearings, and the end of the liquid outlet pipe 615 is connected to the liquid inlet interface of the serpentine heat exchange tube 63.
[0043] The coolant is introduced into the liquid inlet hole 613 through the liquid inlet pipe 614 and flows into the spiral cooling tube 611 through the connecting tube 612, so as to quickly cool the aluminum alloy liquid between the two casting rolls 2 and perform rolling forming. The spiral cooling tubes 611 arranged in a spiral and staggered manner increase the contact area between the coolant and the aluminum alloy liquid, thereby improving the uniformity and efficiency of cooling and forming. The coolant after heat exchange flows into the serpentine heat exchange tube 63 in the heat exchange plate 62 through the liquid outlet pipe 615, so as to perform heat exchange pre-cooling on the high-temperature aluminum alloy liquid in the casting nozzle 4. And because the refluxed coolant has undergone one heat exchange and itself has a certain temperature, it can avoid directly condensing the aluminum alloy liquid in the casting nozzle 4, better assisting the rolling work of the casting roll 2, and avoiding the direct condensation of the aluminum alloy liquid at too high a temperature, resulting in quality problems of the aluminum alloy plate.
[0044] Since the refluxed coolant has undergone secondary heat exchange and has a higher temperature, to ensure the circulating cooling effect of the coolant, the device is also provided with a refrigeration component 65. The refrigeration component 65 includes a partition plate 651 installed inside the liquid storage tank 5, a refrigerator 652 installed on the left side of the liquid storage tank 5, a water pump 653 installed on the liquid storage tank 5. The liquid outlet interface of the water pump 653 is installed with a water delivery pipe 654. The liquid inlet pipes 614 on the two casting rolls 2 are both connected to the water delivery pipe 654. The coolant flowing back into the liquid storage tank 5 through the return pipe 64 flows into the high-temperature chamber separated by the partition plate 651, and the high-temperature coolant is quickly cooled by the refrigerator 652, and then the coolant flowing into the low-temperature chamber on the right after refrigeration is pumped into the water delivery pipe 654 by the water pump 653, and then input into the spiral cooling tube 611 through the liquid inlet pipe 614 to perform condensation rolling forming on the aluminum alloy liquid.
[0045] The driving component 66 includes a toothed ring 661 installed on the front roller shaft of the casting roll 2, and a gear 662 is meshingly connected to the toothed ring 661. A driving motor 663 for driving the gear 662 to rotate is installed on the frame 1. The driving motor 663 is started to drive the gear 662 to rotate, thereby driving the toothed ring 661 to drive the roller shaft of the casting roll 2 to rotate, thereby driving the two casting rolls 2 to rotate away from each other, so as to perform rolling forming on the aluminum alloy liquid.
[0046] Embodiment Two
[0047] Since different customers have different requirements for the thickness of aluminum alloy plates, it is necessary to adjust the distance between the two casting rollers 2 in a targeted manner. Therefore, based on the first embodiment, as shown in FIG. Figures 1-9 As shown, the device is also provided with a distance adjustment component 67, which includes a strip groove 671 opened on the frame 1, and a bearing seat 672 is connected to the strip groove 671 for sliding up and down, and the roller shafts at the front and rear ends of the top casting roller 2 are rotatably connected to the two bearing seats 672, and an electric lifting rod 673 is installed on the top of the frame 1. The free end of the bottom of the electric lifting rod 673 extends into the strip groove 671 and is connected to the bearing seat 672. When it is necessary to adjust the distance between the two casting rollers 2, the electric lifting rod 673 is started to drive the bearing seat 672 to move up and down along the strip groove 671, thereby driving the top casting roller 2 to move up and down, and then realizing the adjustment of the distance between the two casting rollers 2, thereby casting and rolling aluminum alloy plates of different thicknesses, thereby improving the versatility of the device.
[0048] In order to prevent the bearing seat 672 from shaking when moving up and down, a limiting groove 674 is opened inside both sides of the strip groove 671 in the device, and the limiting groove 674 is connected to a slider 675 installed on both sides of the bearing seat 672 for sliding up and down. When the bearing seat 672 moves up and down, it drives the sliders 675 on both sides to move up and down along the limiting groove 674, thereby improving the stability of the up and down movement.
[0049] Example 3
[0050] In order to prevent the casting roll 2 from being contaminated with aluminum chips during the rolling process, which would affect the surface finish of the aluminum alloy plate, based on the second embodiment, Figures 1-8 As shown, the device is also provided with an anti-sticking mechanism 7, which includes an air delivery box 71 installed on the upper and lower sides of the frame 1, and a plurality of flamethrowers 72 facing the casting roller 2 are installed in an array on the air delivery box 71. Laser rangefinders 73 facing the casting roller 2 are installed on the upper and lower sides of the frame 1. Grinding rollers 74 are rotatably connected to the upper and lower sides of the frame 1 and located on the lower side of the casting roller 2. Pulleys 75 are installed at the front ends of the roller shafts of the grinding rollers 74. The two pulleys 75 are internally connected to a transmission belt 76. A stepping motor 77 for driving the bottom pulley 75 to rotate is installed on the frame 1. A scraping assembly 78 for scraping off aluminum slag adhered to the casting roller 2 is provided on the frame 1.
[0051] The liquefied gas is transported into the torch 72 through the gas delivery box 71 and sprayed on the surface of the casting roll 2 to form a carbon deposit layer, thereby protecting the casting roll 2 and preventing the casting roll 2 from sticking aluminum. As the casting roll 2 rotates, the casting roll 2 passes through the laser rangefinder 73, and the laser rangefinder 73 is used to detect the thickness uniformity of the carbon deposit layer on the casting roll 2. If the local carbon deposit layer is too thin, the torch 72 at the corresponding position is started to replenish carbon. If the local carbon deposit layer is too thick, the stepping motor 77 drives the pulley 75 to rotate, and then the drive belt 76 drives the two grinding rolls 74 to rotate, so as to thin the carbon deposit layer at the thicker part of the surface of the casting roll 2, thereby ensuring that the thickness of the carbon deposit layer on the casting roll 2 is consistent and avoiding the uneven surface of the aluminum alloy plate rolled out due to the uneven carbon deposit layer, which affects the performance of the aluminum alloy plate.
[0052] Since the carbon deposit layer on the surface of the casting roll 2 will wear during the rolling of the casting roll 2, and then some aluminum slag adheres to the casting roll 2, the device is also provided with a slag scraping assembly 78. The slag scraping assembly 78 includes mounting back plates 781 installed on the upper and lower sides of the frame 1 and vertically opposite to the two casting rolls 2. A scraper 782 that fits on the surface of the casting roll 2 is installed on the inner side of the mounting back plate 781, and a slag box 783 for collecting the scraped aluminum slag is installed below the scraper 782 on the inner side of the mounting back plate 781. During the rotation of the casting roll 2, the aluminum chips contaminated on its surface are scraped into the slag box 783 by the scraper 782, thereby avoiding the aluminum chips from affecting the surface smoothness of the aluminum alloy plate.
[0053] It should be noted that in this article, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.
[0054] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
