Description

Technical Field

[0001] This utility model relates to the field of aluminum foil hot rolling technology, specifically to an aluminum foil hot rolling device. Background Technology

[0002] Hot rolling, as opposed to cold rolling, refers to rolling processes performed above the recrystallization temperature. After heating, aluminum sheets undergo several rolling passes, followed by edge trimming and straightening to become aluminum foil. This process, known as hot rolling, significantly reduces energy consumption and costs. Hot rolling results in high metal plasticity and low deformation resistance, greatly reducing the energy consumption associated with metal deformation.

[0003] In existing aluminum foil hot rolling equipment, the spacing between adjacent upper and lower rollers needs to be adjusted sequentially during hot rolling, which affects the hot rolling efficiency. At the same time, existing aluminum foil hot rolling equipment lacks a device to filter the coolant, so impurities in the coolant cannot be effectively treated, which in turn affects the hot rolling quality of the coolant on the hot rolling rollers. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide an aluminum foil hot rolling device. By setting multiple upper hot rolling rollers and lower support rollers, the distance between the upper hot rolling rollers and the lower support rollers gradually increases, so that the aluminum material is hot rolled from the end with the larger distance. After the plate passes through multiple upper hot rolling rollers and lower support rollers for hot rolling, the hot rolling of the plate is completed. It is not necessary to adjust the distance between the hot rolling rollers and the support rollers one by one, so as to ensure the hot rolling efficiency and effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum foil hot rolling device, including a liquid collection tank, a filter screen is provided on the upper side of the liquid collection tank, a support frame is provided on the upper side of the liquid collection tank, an upper hot rolling roller is provided between the support frames, a lower support roller is provided on the lower side of the upper hot rolling roller, a top plate is installed on the upper side of the support frame, two hydraulic cylinders are installed on the upper side of the top plate, liquid distribution pipes are provided at equal intervals on the lower side of the top plate, and nozzles are provided at equal intervals on the lower side of the liquid distribution pipes.

[0006] Furthermore, a drain pipe is connected to the outside of the collection tank, and a limit sleeve is provided on the upper side of the drain pipe, with a limit post passing through the limit sleeve.

[0007] Furthermore, an inlet pipe is provided on the outer side of the top plate and at a position perpendicular to the liquid equalization pipe, and the inlet pipe is connected to the liquid equalization pipe by a thread.

[0008] Furthermore, the top plate is welded to the support frame, and the support frame is connected to the limiting post by bolts.

[0009] Furthermore, the limiting sleeve is bolted to the liquid collection tank, and the filter screen is bolted to the liquid collection tank.

[0010] Furthermore, the upper hot rolling roll is connected to drive equipment at both ends, and the liquid equalization pipe is connected to the top plate through pipe clamps.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses multiple upper hot rolling rolls and lower support rolls, with the distance between the upper hot rolling rolls and lower support rolls gradually increasing. This allows the aluminum material to be hot rolled starting from the end with the larger distance. After the plate passes through multiple upper hot rolling rolls and lower support rolls, the hot rolling of the plate is completed. It is not necessary to adjust the distance between the hot rolling rolls and support rolls one by one, thus ensuring the hot rolling efficiency.

[0013] 2. This utility model, through the setting of a liquid collection tank and a filter screen, allows the coolant used for cooling the plate to drip onto the upper side of the liquid collection tank, and the filter screen can filter out impurities in the coolant, thereby ensuring the hot rolling quality of the aluminum foil when the coolant cools the aluminum material again.

[0021] like Figure 1-4 As shown, during hot rolling, the aluminum sheet is placed between the lower support roller 13 and the upper hot rolling roller 12. The upper hot rolling roller 12 and the lower support roller 13 convey and heat the aluminum sheet. After being heated, the aluminum sheet undergoes hot rolling. The hydraulic cylinder 8 can maintain a constant distance between the upper hot rolling roller 12 and the lower support roller 13, thereby ensuring the quality of hot rolling. Cooling liquid is introduced into the liquid inlet pipe 9 and sprayed downwards through the liquid distribution pipe 10 and the nozzle, thereby cooling the aluminum sheet and preventing the aluminum foil from being damaged by excessively high temperatures of the upper hot rolling roller 12 and the lower support roller 13. The cooled liquid falls onto the filter screen 2, which filters the cooling liquid, thereby ensuring that the cooling liquid will not affect the forming quality of the aluminum foil when reused.

[0022] The liquid collection tank 1 is externally connected to a drain pipe 3. A limit sleeve 5 is provided on the upper side of the drain pipe 3, and a limit post 4 is inserted inside the limit sleeve 5.

[0023] A liquid inlet pipe 9 is provided on the outer side of the top plate 7 and at a position perpendicular to the liquid distribution pipe 10. The liquid inlet pipe 9 is connected to the liquid distribution pipe 10 by a thread.

[0024] The top plate 7 is welded to the support frame 6, and the support frame 6 is connected to the limiting column 4 by bolts.

[0025] The limiting sleeve 5 is connected to the liquid collection tank 1 by bolts, and the filter screen 2 is connected to the liquid collection tank 1 by bolts.

[0026] The upper hot rolling roll 12 is connected to the drive equipment at both ends, and the liquid equalization pipe 10 is connected to the top plate 7 through pipe clamps.

[0027] The working principle of the aluminum foil hot rolling device provided by this utility model is as follows: Figures 1-4As shown, during hot rolling, the aluminum sheet is placed between the lower support roller 13 and the upper hot rolling roller 12. The upper hot rolling roller 12 and the lower support roller 13 convey and heat the aluminum sheet. After being heated, the aluminum sheet undergoes hot rolling. The hydraulic cylinder 8 can maintain a constant distance between the upper hot rolling roller 12 and the lower support roller 13, thereby ensuring the quality of hot rolling. Cooling liquid is introduced into the liquid inlet pipe 9 and sprayed downwards through the liquid distribution pipe 10 and the nozzle, thereby cooling the aluminum sheet and preventing the aluminum foil from being damaged by excessively high temperatures of the upper hot rolling roller 12 and the lower support roller 13. The cooled liquid falls onto the filter screen 2, which filters the cooling liquid, thereby ensuring that the cooling liquid will not affect the forming quality of the aluminum foil when reused.
