Description

Technical Field

[0001] The invention relates to the technical field of aluminum cold rolling, and in particular to an aluminum cold rolling production device for can body materials and a production method thereof. Background Art

[0002] Aluminum cold rolling mill is mainly used to cold roll hot rolled aluminum coils or aluminum plates again to reduce their thickness and improve the surface finish and flatness of aluminum. Through cold rolling, the hardness and strength of aluminum can also be improved, thereby enhancing its physical properties and service life.

[0003] The Chinese patent with the publication number CN220716871U discloses a decontamination device for a cold rolling mill roll wheel for an aluminum profile production line, comprising a base, a frame plate fixedly connected to the top of the base, a cold rolling roll arranged inside the frame plate, and a support fixedly connected to the top of the base located below the cold rolling roll. The decontamination device for a cold rolling mill roll wheel for an aluminum profile production line, through the provided adjustment mechanism, the staff only needs to start the driving motor to drive the threaded shafts on the left and right sides to rotate synchronously, so that the threaded barrels on the left and right sides move up and down synchronously to drive the decontamination tool to rise and fall, so that the staff can adjust the height of the decontamination tool at will, so that the decontamination tool can clean the cold rolling rolls of different diameters and heights, and the sliding cylinder is slidably connected to the outer ring of the fixed rod to limit the threaded barrel through the connecting arm and the sleeve plate, so that the threaded barrel cannot rotate and can only move up and down following the rotation of the threaded shaft.

[0004] Although the above device is equipped with a decontamination device for the cold rolling mill roll wheel, which is used to clean the dirt and impurities on the surface of the cold rolling roll to increase its service life, it can only perform simple physical cleaning and cannot effectively monitor the surface roughness and wear state of the cold rolling roll. During the high-speed rolling process, the surface roughness of the cold rolling roll will decrease rapidly due to friction and wear, resulting in a decrease in the friction between the cold rolling roll and the strip. This reduction in friction may not meet the requirements of continuous rolling, causing the strip to slip or deviate during the rolling process, thereby affecting the quality and stability of the product.

[0005] At the same time, when the existing equipment finds that the cold rolling roll needs to be replaced, since the newly replaced cold rolling roll has a low temperature in the initial state, if it is directly put into production, it may cause insufficient friction coefficient between the cold rolling roll and the strip, affecting the rolling effect. Warm roll preparation is required to preheat the cold rolling roll to a suitable working temperature, thereby improving the friction and lubrication effect between the cold rolling roll and the strip, ensuring the stability of the rolling process and product quality. It takes a long time to heat the cold rolling roll, which greatly affects the working efficiency. Summary of the invention

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] See also Figures 1 to 10As shown, an aluminum cold rolling production device for can body material includes a stable cold rolling device for rolling an aluminum alloy strip 7. The aluminum can body material of the present invention is an aluminum alloy strip 7. The stable cold rolling device includes a driving platform 1, a cold rolling roller 2, an outer wall cleaning mechanism 3, a first ball screw slide 4, an identification and detection device 5 and a spare replacement installation platform 6; two cold rolling rollers 2 are provided and installed on the driving platform 1, and the cold rolling rollers 2 are transmission-connected to the driving end of the driving platform 1, and the driving end of the driving platform 1 drives the cold rolling rollers 2 to rotate. A cold rolling gap for the cold-rolled can material is reserved between the two cold rolling rollers 2; two outer wall cleaning mechanisms 3 are provided, and an outer wall cleaning mechanism 3 is provided on the side of each cold rolling roller 2, and the outer wall cleaning mechanism 3 is fixedly connected to the driving platform 1, and the working end of the outer wall cleaning mechanism 3 extends to the outer wall of the cold rolling roller 2, and the outer wall cleaning mechanism 3 is used to clean foreign matter attached to the outer wall of the cold rolling roller 2; two first ball screw slides 4 are provided, and a first ball screw slide 4 is installed on the working end of each outer wall cleaning mechanism 3; two identification and detection devices 5 are provided, and an identification and detection device 5 is installed on the movable end of each first ball screw slide 4, and the movable end of each first ball screw slide 4 drives the corresponding identification and detection device 5 to slide, and the detection end of the identification and detection device 5 is arranged opposite to the outer wall of the cold rolling roller 2, and each identification and detection device 5 corresponds to detecting the outer wall of a cold rolling roller 2; the spare replacement mounting platform 6 is arranged on the side of the driving platform 1, and the spare roller 64 to be replaced is stored on the spare replacement mounting platform 6.

[0037] Before rolling, the aluminum alloy strip 7 is subjected to rolling oil hot spraying at the edge of the aluminum alloy strip 7 through the edge hot spraying system, and the edge hot spraying system is composed of multiple nozzles. After the edge of the aluminum alloy strip 7 is subjected to rolling oil hot spraying, the friction force and lubrication effect between the aluminum alloy strip 7 and the cold rolling roller 2 can be improved to ensure the cold rolling stability.

[0038] The driving platform 1 is used to drive the rotation of the cold rolling roller 2. The cold rolling roller 2 is used to cold roll the aluminum alloy strip 7. The outer wall cleaning mechanism 3 is used to clean the dirt and foreign matter on the surface of the cold rolling roller 2. The first ball screw slide 4 is used to drive the identification and detection device 5 to move along the cold rolling roller 2. The identification and detection device 5 is preferably an industrial camera, which is used to monitor the surface roughness and wear state of the cold rolling roller 2. The spare replacement installation platform 6 is used to store the spare roller 64 heated to a suitable temperature.

[0039] The aluminum alloy strip 7 is fed between the symmetrically arranged cold rolling rollers 2, and the driving platform 1 drives the cold rolling rollers 2 to rotate, and the aluminum alloy strip 7 is subjected to multiple batch cycle rolling. The rolling rate of each rolling is 25-30% for the first time, 35-40% for the second time, and 40-50% for the last time according to different rolling stages.

[0040] During the rolling process, rolling oil and dirt will adhere to the surface of the cold rolling roller 2. The outer wall cleaning mechanism 3 contacts the surface of the cold rolling roller 2 to clean the attachments and ensure the rolling effect and stability. The first ball screw slide 4 drives the industrial camera to move horizontally along the length direction of the cold rolling roller 2 to conduct a comprehensive inspection of the surface of the cold rolling roller 2. The industrial camera detects the roughness and wear state of the surface of the cold rolling roller 2 to detect potential problems in a timely manner.

[0041] If the industrial camera finds that the surface of the cold rolling roller 2 is damaged, which affects the rolling quality, it needs to be replaced in time. The staff uses the spare roller 64 heated on the spare replacement installation platform 6 to replace it, thereby improving the replacement efficiency and ensuring the rolling continuity.

[0042] The device realizes efficient cleaning, real-time monitoring, rapid replacement and stable rolling of the surface of the cold rolling roller 2, thereby improving production efficiency and product quality.

[0043] See also Figures 1 to 3 As shown, a circulating cooling chamber is provided inside the cold rolling roller 2, a liquid inlet 21 and a liquid outlet 22 are provided on the side of the cold rolling roller 2, both the liquid inlet 21 and the liquid outlet 22 are connected to the circulating cooling chamber, a fixed connecting hole 23 is also provided on the outside of the cold rolling roller 2, and a coating layer 24 is provided on the outer surface of the cold rolling roller 2.

[0044] The cold rolling roller 2 is a key component in the cold rolling process, and a circulating cooling chamber is provided inside the cold rolling roller 2. By circulating the coolant, the temperature of the cold rolling roller 2 is effectively controlled to prevent overheating caused by long-term operation, thereby ensuring the stability of the rolling process and the quality of the aluminum alloy strip 7.

[0045] The circulating cooling chamber inside the cold rolling roller 2 is connected to the coolant system through the side liquid inlet 21 and the liquid outlet 22. The coolant circulates in the chamber, absorbing and taking away the heat generated during the cold rolling process, thereby maintaining the cold rolling roller 2 within a suitable operating temperature range.

[0046] The coating layer 24 is coated on the outer surface of the cold rolling roller 2, and the coating layer 24 has a layer of hard chrome. The coating layer 24 is achieved by an electroplating process, in which lead is used as an anode and the cold rolling roller 2 is used as a cathode, and electroplating is performed in a bath containing chromic anhydride, sulfuric acid and a catalyst. The hard chrome layer has excellent hardness and wear resistance, and can effectively improve the rolling effect and life of the cold rolling roller 2. The fixed connection hole 23 is used to cooperate with the spare replacement mounting table 6 for installation or removal.

[0047] See also Figure 1 and Figure 4 As shown, the outer wall cleaning mechanism 3 includes a mounting bracket 31 mounted on the driving platform 1, a linear drive 32 is mounted on the mounting bracket 31, and a multi-stage cleaning device 33 is mounted on the extended end of the linear drive 32.

[0048] During the rolling process, foreign matter such as rolling oil and dirt will adhere to the surface of the cold roll 2. In order to ensure the rolling effect and stability, the surface of the cold roll 2 needs to be cleaned regularly or continuously. When the surface of the cold roll 2 needs to be cleaned, the linear drive 32 is started. The linear drive 32 drives the multi-stage cleaning device 33 to move toward the cold roll 2. As the linear drive 32 moves, the cleaning device collides with the surface of the cold roll 2. Since the cold roll 2 rotates during the rolling process, the rotating cold roll 2 will rub against the multi-stage cleaning device 33, and the multi-stage cleaning device 33 can effectively remove rolling oil, dirt and other foreign matter attached to the surface of the cold roll 2. The long-term stability and rolling effect of the cold roll 2 are ensured.

[0049] See also Figure 4 and Figure 5 As shown, the multi-stage cleaning device 33 includes a fixed mounting plate 331 installed at the extending end of the linear drive 32, a telescopic mounting frame 332 is installed on the fixed mounting plate 331, a guide column is provided on the top of the telescopic mounting frame 332, the guide column is slidably connected to the fixed mounting plate 331, a push spring 333 is installed between the telescopic mounting frame 332 and the fixed mounting plate 331, an adsorption scraper 334 is installed at the bottom of the telescopic mounting frame 332, the adsorption scraper 334 is in the shape of an inclined strip, the adsorption scraper 334 fits with the outer wall of the cold rolling roller 2, a plurality of adsorption holes 3341 are provided on the side of the adsorption scraper 334, and a two-stage cleaning device is also installed on the side of the telescopic mounting frame 332.

[0050] The fixed mounting plate 331 is firmly mounted on the extended end of the linear drive 32 to provide stable support for the entire cleaning device. The telescopic mounting frame 332 and the fixed mounting plate 331 are connected by sliding to achieve flexible telescopic function. The push spring 333 is installed between the telescopic mounting frame 332 and the fixed mounting plate 331 to provide continuous elastic force to ensure that the adsorption scraper 334 can fit tightly on the outer wall of the cold rolling roller 2. The adaptability to slight changes in the surface of different cold rolling rollers 2 is improved.

[0051] The adsorption scraper 334 is in the shape of an inclined strip, which fits perfectly with the outer wall of the cold rolling roller 2 to ensure the maximum cleaning effect. The adsorption scraper 334 is provided with an adsorption hole 3341, which is used to connect the adsorption device. During the cleaning process, the adsorption device absorbs and scrapes away the oil and dirt on the outer wall of the cold rolling roller 2 through the adsorption hole 3341 to prevent it from contaminating the cold rolling roller 2 or the working environment again. The two-stage cleaning device is installed on the side of the telescopic mounting frame 332 as a supplement to the secondary cleaning of the cold rolling roller 2.

[0052] During the cleaning process, the linear drive 32 drives the multi-stage cleaning device 33 to move toward the cold roller 2 until the adsorption scraper 334 is in close contact with the surface of the cold roller 2. As the cold roller 2 rotates, the adsorption scraper 334 uses its inclined strip design and the function of the adsorption hole 3341 to effectively scrape and adsorb the oil and dirt attached to the surface of the cold roller 2. At the same time, the push spring 333 keeps the adsorption scraper 334 in close contact with the surface of the cold roller 2 to ensure the cleaning effect. When more in-depth cleaning is required, the linear drive 32 continues to press down to start the second-stage cleaning device to further improve the cleaning effect. Effective cleaning not only improves the long-term stability and rolling effect of the cold roller 2, but also ensures that the subsequent identification and detection device 5 can accurately detect the outer wall of the cold roller 2. The surface of the cold roller 2 after cleaning is clean, free of oil and dirt, which greatly improves the accuracy and reliability of the detection of the identification and detection device 5.

[0053] See also Figure 4 and Figure 5 As shown, the two-stage cleaning device includes a fixed bracket 335 installed on the side of the telescopic mounting frame 332, and a first rotating driver 337 is installed on the fixed bracket 335. A cleaning roller 336 is installed on the driving end of the first rotating driver 337, and the cleaning roller 336 is detachably connected to the driving end of the first rotating driver 337.

[0054] During the cleaning process, when the linear drive 32 drives the multi-stage cleaning device 33 to move toward the cold rolling roller 2 and makes the adsorption scraper 334 tightly contact the surface of the cold rolling roller 2, if more in-depth cleaning is required, the linear drive 32 will continue to press down.

[0055] As the linear drive 32 is pressed downward, the fixed bracket 335 and the cleaning roller 336 of the second-stage cleaning device will gradually approach the outer wall of the cold roller 2. When the cleaning roller 336 contacts the outer wall of the cold roller 2, the first rotary drive 337 starts to work and drives the cleaning roller 336 to rotate. The rotating cleaning roller 336 uses the cleaning material on its surface to closely contact the cold roller 2 to effectively scrape and clean the oil, dirt and other foreign matter attached to the surface of the cold roller 2.

[0056] During the cleaning process, the cleaning roller 336 may be worn due to friction, but since it is detachably connected to the driving end of the first rotating driver 337, a new cleaning roller 336 can be easily replaced. This improves the convenience of maintenance and replacement, and reduces production costs and downtime.

[0057] The use of the two-stage cleaning device further improves the cleaning effect of the cold rolling roller 2, ensuring the long-term stability and rolling effect of the cold rolling roller 2. The surface of the cold rolling roller 2 after cleaning is cleaner, free of oil and dirt, which helps to improve the accuracy and reliability of the subsequent identification and detection device 5.

[0058] See also Figure 1 and Figure 2 As shown, the spare replacement installation platform 6 includes a movable adjustment installation platform 61, and a roller placement platform 62 is installed at the adjustment end of the movable adjustment installation platform 61. The spare replacement installation platform 6 also includes a circulating preheating device 63, and the circulating preheating device 63 is installed between the cold rolling roller 2 and the spare roller 64.

[0059] The spare replacement installation table 6 is arranged beside the driving table 1 and is used to store the spare rollers 64 heated to a suitable temperature.

[0060] The standby replacement installation platform 6 includes a movable adjustment installation platform 61 and a roll placement platform 62. The roll placement platform 62 is used to limit and place the standby roll 64, while the movable adjustment installation platform 61 is used to adjust the position of the roll placement platform 62. The movable adjustment installation platform 61 has the function of lifting and moving the height of the roll placement platform 62, and can also move the position of the roll placement platform 62 horizontally. When the roll placement platform 62 is adjusted and moved, the position of the standby roll 64 can be adjusted, so that the staff can easily install the standby roll 64, effectively saving manpower.

[0061] The circulating preheating device 63 connects the cold roller 2 and the spare roller 64, so that the coolant circulates between the cold roller 2 and the spare roller 64. This can not only effectively reduce the temperature of the cold roller 2 during operation, but also transfer the temperature on the cold roller 2 to the spare roller 64 to achieve the preheating of the spare roller 64. The preheated spare roller 64 can reach the working temperature more quickly when replaced, thereby improving the replacement efficiency and rolling continuity. When replacing the spare roller 64, the circulating preheating device 63 between the cold roller 2 and the spare roller 64 needs to be disassembled, and the circulating preheating device 63 is reconnected to the new spare roller 64 after replacement.

[0062] The movable adjustment mounting platform 61 is an existing device and will not be described in detail here.

[0063] See also Figure 2 and Figure 6 As shown, the roller placement platform 62 includes a horizontal mounting plate 621 installed on the movable and adjustable mounting platform 61, and a guide storage box 622 and a disassembly guide box 623 are symmetrically installed on the horizontal mounting plate 621. The guide storage box 622 and the disassembly guide box 623 have the same structure. A sliding guide rail 6221 is also installed inside the guide storage box 622. A pushing adjustment device 6222 for pushing the spare roller 64 is also installed inside the guide storage box 622. The roller placement platform 62 also includes a plurality of heating tubes installed inside the guide storage box 622.

[0064] The guide storage box 622 is used for limiting the storage of the spare roller 64. It is ensured that the spare roller 64 will not be damaged or shifted during storage. The disassembly guide box 623 is used to guide the disassembled cold rolling roller 2, which is convenient for the staff to quickly disassemble and subsequently process.

[0065] The sliding guide rail 6221 is installed inside the guide storage box 622, and is used to limit and guide the stable movement of the spare roller 64 in the horizontal direction. It ensures the stability of the spare roller 64 during the installation and removal process, and also improves the accuracy of the operation. The heating pipe is installed inside the guide storage box 622, and is used to quickly heat the spare roller 64. Through the action of the heating pipe, the spare roller 64 can reach a suitable working temperature in a short time, thereby improving the rolling efficiency after replacement. The heating pipe is used in conjunction with the circulating preheating device 63 to achieve more efficient and uniform preheating of the spare roller 64, ensuring the preheating effect. The push adjustment device 6222 is used to push the spare roller 64 to slide horizontally along the sliding guide rail 6221. It allows the staff to easily operate the spare roller 64 in and out, further improving the convenience and efficiency of replacing the cold rolling roller 2.

[0066] See also Figure 6 and Figure 7 As shown, the pushing and adjusting device 6222 includes a second ball screw slide 6223 installed at the bottom of the guide storage box 622, and the movable end of the second ball screw slide 6223 is installed with a vertical mounting frame 6224, and a connecting sleeve 6225 is installed on the vertical mounting frame 6224. A second rotation driver 6226 is also installed on the vertical mounting frame 6224, and the output end of the second rotation driver 6226 is transmission-connected to the connecting sleeve 6225.

[0067] In the initial state, the connecting sleeve 6225 is installed on the movable end of the second ball screw slide 6223 through the vertical mounting frame 6224. At this time, the connecting sleeve 6225 and one end of the spare roller 64 are in a connectable state, but are not actually connected.

[0068] When it is necessary to push the spare roller 64 on the sliding guide rail 6221 to connect with the driving platform 1, first move the movable adjustment mounting platform 61 to a suitable position, dock the connecting sleeve 6225 with one end of the spare roller 64, and then the staff connects the fixed connection hole 23 of the spare roller 64 through the side of the connecting sleeve 6225 with the bolt. Then, start the second ball screw slide 6223 to move its movable end forward. Since the connecting sleeve 6225 is installed on the movable end of the second ball screw slide 6223, the connecting sleeve 6225 will also move with the movement of the movable end. During the movement, the connecting sleeve 6225 will drive the spare roller 64 to move toward the driving platform 1. When the cold rolling roller 2 needs to be replaced, the disassembly guide box 623 is used to disassemble and guide the cold rolling roller 2 on the driving platform 1 in the same way.

[0069] In order to ensure that the installation angle of the spare roller 64 is accurate, the connecting sleeve 6225 can be driven to rotate by the second rotary driver 6226. When the connecting sleeve 6225 rotates, it will drive the spare roller 64 connected thereto to rotate synchronously. In this way, the rotation adjustment of the spare roller 64 can be achieved to ensure that it is consistent with the angle of the drive platform 1 during installation, thereby improving the stability of the installation. When the spare roller 64 is installed, the task of the push adjustment device 6222 is completed, and it can return to the initial state and wait for the next operation. The precise pushing and angle adjustment of the spare roller 64 is achieved, thereby ensuring the efficiency and accuracy of the roller replacement.

[0070] See also Figure 2 , Figure 8 , Fig. 9 and Fig.10 As shown, the circulation preheating device 63 includes two rotating circulation connectors 631, one end of the cold rolling roller 2 is connected to the rotating circulation connector 631, and the circulation preheating device 63 also includes a fixed circulation connector 632 installed on the spare rolling roller 64, each rotating circulation connector 631 is connected to the fixed circulation connector 632 through a connecting pipe 634, and the two rotating circulation connectors 631 are connected through a connecting pipe 634, and a liquid injection valve 633 is installed on the connecting pipe 634. The rotating circulation connector 631 includes a rotating connecting sleeve 6311, a limit mounting plate 6312 is provided at one end of the rotating connecting sleeve 6311 away from the cold rolling roller 2, and the rotating connecting sleeve 6311 and the limit mounting plate 6312 are coaxially arranged, a first flow hole 6313 and a second flow hole 6314 are also provided on the limit mounting plate 6312, a rotating insert 6315 is installed on the first flow hole 6313, one end of the rotating insert 6315 away from the first flow hole 6313 is connected to the liquid inlet 21 of the cold rolling roller 2, and a flow impeller 6316 is installed on the outer side of the rotating insert 6315.

[0071] The coolant enters the circulating cooling chamber inside the cold rolling roller 2 through the liquid inlet 21 of the cold rolling roller 2 to cool the cold rolling roller 2. The cooled coolant flows out from the liquid outlet 22 of the cold rolling roller 2. The rotating connecting sleeve 6311 and the limiting mounting plate 6312 are rotatably connected.

[0072] When the cold rolling roller 2 rotates, it will drive the rotating connecting sleeve 6311 and the rotating insert 6315 to rotate synchronously. A circulation impeller 6316 is installed on the outside of the rotating insert 6315. When the rotating insert 6315 rotates, it will drive the circulation impeller 6316 to rotate. The rotation of the circulation impeller 6316 will accelerate the flow of the coolant, thereby improving the cooling efficiency. When the coolant flows, it will flow out through the second circulation hole 6314 of the limiting mounting plate 6312. The outflowing coolant will flow at a uniform speed between the rotating circulation connector 631 and the fixed circulation connector 632 through the connecting pipe 634. After the coolant flows in the fixed circulation connector 632, it will flow back to the liquid inlet 21 of the cold rolling roller 2 through the connecting pipe 634 again to form a cycle.

[0073] The coolant circulates between the rotating circulation connector 631 and the fixed circulation connector 632. Since the coolant absorbs the heat of the cold rolling roller 2 during the circulation process, when the coolant flows through the fixed circulation connector 632, the heat is transferred to the spare rolling roller 64, thereby preheating the spare rolling roller 64.

[0074] The amount of coolant in the connecting pipe 634 can be effectively controlled by adjusting the filling valve 633 . When the rotating circulation connector 631 and the fixed circulation connector 632 need to be disassembled, the coolant can be discharged through the filling valve 633 .

[0075] The circulating preheating device 63 improves the cooling efficiency of the cold rolling roller 2 and also ensures that the spare rolling roller 64 can quickly reach the working temperature when replaced, thereby improving production efficiency and product quality.

[0076] A production method of an aluminum cold rolling production device for can body material comprises the following steps: S1. Prepare the spare rolls 64 heated to a suitable temperature on the spare replacement installation table 6. Before the aluminum alloy strip 7 is fed into the production device, the edge of the strip is thermally sprayed with rolling oil by the edge thermal spray system.

[0077] S2. Feed the aluminum alloy strip 7 between the symmetrically arranged cold rolling rollers 2, start the drive table 1, drive the cold rolling rollers 2 to rotate, and start to perform multiple batch cycle rolling on the aluminum alloy strip 7. According to the different rolling stages, adjust the rolling rate of each rolling: the first rolling rolling rate is 25-30%, the second rolling rolling rate is 35-40%, and the last rolling rolling rate is 40-50%.

[0078] S3. During the rolling process, the outer wall cleaning mechanism 3 contacts the surface of the cold rolling roller 2 to clean the rolling oil and dirt attached to the cold rolling roller 2 to ensure the rolling effect and stability. At the same time, the first ball screw slide 4 drives the identification and detection device 5 to move horizontally along the cold rolling roller 2 to conduct a comprehensive inspection of the surface of the cold rolling roller 2.

[0079] S4. If the identification and detection device 5 finds that the surface of the cold rolling roller 2 is damaged, which affects the rolling quality, it needs to be replaced in time.

[0080] S5. The staff uses the heated spare roller 64 on the spare replacement installation table 6 to replace the roller, ensuring that the replacement process is rapid and does not affect the continuity of rolling.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
