Description

Technical Field

[0001] This application relates to the field of aluminum strip processing technology, and in particular to an aluminum strip rolling apparatus. Background Technology

[0002] Aluminum strip rolling is a key process that uses rolls to apply high pressure to plastically deform the metal (cold rolling pressure reaches 1500-2500MPa) to achieve thickness reduction and performance optimization. Rolling oil, as a process medium, directly participates in the physicochemical process of the deformation zone, and its use and subsequent cleaning form a closed loop for quality assurance.

[0003] According to technical requirements, some aluminum strips need to undergo heat treatment after rolling. The surface of the aluminum strips after mechanical cleaning (e.g., online vacuum suction, negative pressure 0.08-0.095MPa, to remove most of the floating oil) is not thoroughly degreased. During the annealing process, the rolling oil remaining on the surface of the aluminum strips is easily carbonized to form black streaks. In addition, local high temperatures can cause grain boundary corrosion, which in turn affects the quality of the aluminum strips. Summary of the Invention

[0004] This application aims to at least partially solve one of the technical problems in the aforementioned technologies.

[0005] Therefore, one objective of this application is to provide an aluminum strip rolling apparatus that, by increasing the cleaning frequency of the aluminum strip, further reduces the residual rolling oil on the surface of the aluminum strip, thereby ensuring the product quality of the aluminum strip after heat treatment.

[0006] To achieve the above objectives, a first aspect of this application provides an aluminum strip rolling apparatus, comprising: a housing, a rolling mechanism, multiple rollers, and a spraying mechanism. The housing has an internal partition, with a first chamber and a second chamber located on either side of the partition. The first chamber contains rolling oil, and the second chamber contains a cleaning solvent. The rolling mechanism is connected to the housing, located in the first chamber, and its bottom is immersed in the rolling oil. The multiple rollers are rotatably disposed within the second chamber, forming a first space and a second space with the rolled aluminum strip. The first space and the second space are arranged in a triangular structure. The spraying mechanism is mounted on the housing, with one end connected to the cleaning solvent and the other end rotatably connected to the housing, located within the first and second spaces.

[0007] In addition, the aluminum strip rolling apparatus proposed in the above embodiments of this application may also have the following additional technical features:

[0008] Furthermore, the aluminum strip rolling apparatus of this application also includes a drying mechanism, which includes a blower and two air nozzles. The blower is mounted on the housing, and the air nozzles are connected to the blower. The two air nozzles are respectively installed inside the second chamber and arranged near the end of the aluminum strip. The two air nozzles are respectively located above and below the aluminum strip. A first drying zone is formed above the aluminum strip, and a second drying zone is formed between the aluminum strip and the housing.

[0009] Furthermore, the bottom of the first space is immersed in the interior of the cleaning solvent.

[0010] Furthermore, a gap is provided at the bottom of the second space.

[0011] Furthermore, openings are provided on both sides of the box and on the partition, and reversing rollers are rotatably installed at the openings.

[0012] Furthermore, the rolling mechanism includes a drive roller, a drive motor, a pressure roller, two sets of symmetrically arranged connecting assemblies, and a drive adjustment assembly. The drive roller is rotatably connected to the housing, with one end penetrating the inner wall of the housing. The drive motor is mounted on the housing, and its output shaft is connected to one end of the drive roller. The pressure roller is located above the drive roller and is rotatably connected to the two sets of symmetrically arranged connecting assemblies. The connecting assemblies and the drive adjustment assembly are respectively mounted on the housing, and the drive adjustment assembly is connected to the two sets of connecting assemblies.

[0013] Furthermore, the spraying mechanism includes two spray bars, a linkage assembly, a transmission assembly, two rotary connectors, a connecting pipe, a solvent circulation supply, and a pipe body. The two spray bars are rotatably connected to the housing, and the linkage assembly is disposed between the two spray bars. The other end of the drive roller and one end of each spray bar penetrate the inner wall of the housing. The transmission assembly is connected to the other end of the drive roller and one end of each spray bar. The other end of each spray bar penetrates the inner wall of the housing, and the two rotary connectors are respectively mounted on the other end of the corresponding spray bars. The solvent circulation supply is connected to the connecting pipe and the pipe body. One end of the connecting pipe is connected to the two rotary connectors, and one end of the pipe body penetrates the outer wall of the housing. The pipe body is connected to the cleaning solvent.

[0014] Compared with the prior art, the technical solution provided in this application has the following beneficial effects: In the aluminum strip rolling device of this application embodiment, under the action of multiple rollers, the aluminum strip forms a first space and a second space arranged in a triangular structure inside the second chamber. In the above two spaces, the spray mechanism can rotate to clean the surface of the aluminum strip multiple times. In addition, under the reflection effect of the triangular space, the cleaning frequency of the aluminum strip surface is further increased, and the residual rolling oil on the surface of the aluminum strip is reduced, thereby ensuring the product quality of the aluminum strip after heat treatment.

[0023] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0024] The aluminum strip rolling apparatus of this application embodiment is described below with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown, the aluminum strip rolling apparatus of this application embodiment may include: a housing 1, a rolling mechanism 2, multiple rollers 3, and a spraying mechanism 4.

[0026] The box 1 has a partition 11 inside, and a first chamber 12 and a second chamber 14 are respectively provided on both sides of the partition 11. The first chamber 12 contains rolling oil 13, and the second chamber 14 contains cleaning solvent 15.

[0027] It should be noted that the cleaning solvent 15 described in this embodiment can be a solvent with a pH of 9 to 11 and a temperature of 60°C to 80°C, in order to saponify residual grease.

[0028] The rolling mechanism 2 is connected to the housing 1. The rolling mechanism 2 is located in the first chamber 12, and its bottom is immersed in the rolling oil 13.

[0029] It is understandable that the bottom of the rolling mechanism 2 is immersed in the interior of the rolling oil 13, which allows the rolling oil 13 to fully contact the aluminum strip during the rolling process, avoiding dry friction on the surface of the aluminum strip and ensuring the quality of the aluminum strip product.

[0030] Multiple rollers 3 are rotatably disposed inside the second chamber 14, and a first space 31 and a second space 32 are formed between the multiple rollers 3 and the rolled aluminum strip.

[0031] It should be noted that the number of rollers 3 described in this embodiment can be 6, and their arrangement is as follows: Figure 2 As shown.

[0032] The first space 31 and the second space 32 are arranged in a triangular structure.

[0033] It is understandable that the first space 31 and the second space 32 are arranged in a triangular structure, which can clean the surface of the aluminum strip multiple times during the rotation of the spray mechanism 4. In addition, the reflection effect of the triangular space further increases the cleaning frequency of the aluminum strip surface, reduces the residue of rolling oil on the aluminum strip surface, and thus ensures the product quality of the aluminum strip after heat treatment.

[0034] The spray mechanism 4 is installed on the housing 1. One end of the spray mechanism 4 is connected to the cleaning solvent 15, and the other end of the spray mechanism 4 is rotatably connected to the housing 1. The other end of the spray mechanism 4 is located in the first space 31 and the second space 32. The spray mechanism 4 is used to clean the surface of the aluminum strip in the first space 31 and the second space 32, and to treat the cleaning solvent 15 after use.

[0035] In the above embodiments, one end of the aluminum strip can be arranged on an external unwinding device, and the other end of the aluminum strip can be inserted into the interior of an external heat treatment device.

[0036] Specifically, one end of the aluminum strip released by the external unwinding device first passes through the interior of the rolling mechanism 2, then passes through the partition 11, passes through multiple rollers 3 and then leaves the rolling device, and finally enters the interior of the external heat treatment equipment.

[0037] After passing through the rolling mechanism 2, the aluminum strip can undergo cold rolling. At the same time, some cold rolling oil adheres to the surface of the aluminum strip. The aluminum strip then enters the interior of the second chamber 14. In the second chamber 14, the aluminum strip passes through the first space 31 and the second space 32 in sequence. Since the above spaces are arranged in a triangular structure, the surface of the aluminum strip can be cleaned multiple times when the spraying mechanism 4 rotates and cleans. In addition, the reflection effect of the triangular space further increases the cleaning frequency of the aluminum strip surface, reduces the residue of rolling oil on the aluminum strip surface, and thus ensures the product quality of the aluminum strip after heat treatment.

[0038] It should be noted that within the first space 31, the spraying mechanism 4 rotates clockwise to clean the surface of the aluminum strip. As the aluminum strip is about to detach from the first space 31, the spraying mechanism 4 creates a counteracting effect with the aluminum strip, thereby further improving the degreasing effect on the surface of the aluminum strip.

[0039] Inside the second space 32, the spraying mechanism 4 rotates counterclockwise to clean the aluminum strip. The spraying mechanism 4 can clean the lower surface of the aluminum strip. When the aluminum strip is about to leave the second space 32, the spraying mechanism 4 forms a counter-current effect with the aluminum strip here, thereby further improving the degreasing effect on the surface of the aluminum strip.

[0040] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, it also includes a drying mechanism 5, which includes a blower 51 and two blow nozzles 52.

[0041] The blower 51 is installed on the housing 1, and the nozzle 52 is connected to the blower 51. The two nozzles 52 are respectively installed inside the second chamber 14 and are arranged near the end of the aluminum strip.

[0042] Two air nozzles 52 are located above and below the aluminum strip, respectively. A first drying zone 53 is formed above the aluminum strip, and a second drying zone 54 is formed between the aluminum strip and the housing 1.

[0043] In the above embodiments, reference is made to Figure 2 As shown, the hot air provided by the blower nozzle 52 located above the aluminum strip moves along the upper surface of the aluminum strip (opposite to the direction of movement of the aluminum strip at this time). After being blocked by a roller 3, the hot air rises along the surface of the aluminum strip that forms the second space 32, thereby accelerating the air flow rate on the upper surface of the aluminum strip and creating a drying effect.

[0044] In addition, the hot air provided by the blower nozzle 52 located below the aluminum strip moves along the lower surface of the aluminum strip (opposite to the direction of movement of the aluminum strip at this time), and then moves towards the inner wall of the box 1 after being blocked by the surface of the cleaning solvent 15. Since the blower nozzle 52 is located in the negative pressure zone, this part of the hot air returns to the blower nozzle 52, thus forming a drying circulation effect.

[0045] It is understandable that the hot air moves in the opposite direction to the aluminum strip, which creates a recoil effect, thereby optimizing the drying effect on the surface of the aluminum strip.

[0046] In one embodiment of this application, such as Figure 2 As shown, the bottom of the first space 31 is immersed in the interior of the cleaning solvent 15.

[0047] Understandably, the bottom of the first space 31 is immersed in the interior of the cleaning solvent 15, which can create a soaking effect on the entire aluminum strip, so that the rolling oil can be more easily removed from the aluminum strip when the spray mechanism 4 rotates for cleaning.

[0048] In one embodiment of this application, such as Figure 2 As shown, the bottom of the second space 32 is provided with a gap 61.

[0049] It should be noted that a gap 61 is provided at the bottom of the second space 32, which allows the cleaning solvent 15 sprayed by the spraying mechanism 4 to quickly leave the interior of the second space 32.

[0050] In addition, at gap 61, cleaning solvent 15 gathers and flows at a relatively fast rate, which can form a rinsing function at this point, thereby improving the degreasing effect of aluminum strip.

[0051] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, openings 71 are provided on both sides of the box body 1 and on the partition plate 11, and a reversing roller 72 is rotatably installed at the opening 71.

[0052] It should be noted that the height of the reversing roller 72 on one side of the housing 1 and at the partition 11 is greater than the rolling position, so that after the aluminum strip is rolled, the surface rolling oil 13 can flow back to the interior of the first chamber 12, reducing the pressure of subsequent cleaning.

[0053] In one embodiment of this application, such as Figure 2 and Figure 4 As shown, the rolling mechanism 2 includes a drive roller 21, a drive motor 22, a pressure roller 23, two sets of symmetrically arranged connecting components 24, and a drive adjustment component 25.

[0054] The drive roller 21 is rotatably connected to the housing 1, and one end of the drive roller 21 penetrates the inner wall of the housing 1. The drive motor 22 is mounted on the housing 1, and the output shaft of the drive motor 22 is connected to one end of the drive roller 21. The pressure roller 23 is located above the drive roller 21 and is rotatably connected to two sets of symmetrically arranged connecting components 24. The connecting components 24 and the drive adjustment components 25 are respectively mounted on the housing 1, and the drive adjustment components 25 are connected to the two sets of connecting components 24.

[0055] In the above embodiments, the specific structure and working principle of the drive adjustment component 25 and the connection component 24 have been disclosed in the prior art, so they will not be described in detail here.

[0056] The drive adjustment component 25 is engaged with two sets of symmetrically arranged connecting components 24. The drive adjustment component 25 can adjust the position of the pressure roller 23 through the connecting components 24, thereby changing the distance between the drive roller 21 and the pressure roller 23, and thus is suitable for processing aluminum strips of different specifications.

[0057] In one embodiment of this application, such as Figure 2 and Figure 5 As shown, the spray mechanism 4 includes two spray bars 41, a linkage assembly 42, a transmission assembly 43, two rotary connectors 44, a connecting pipe 45, a solvent circulation supply device 46, and a pipe body 47.

[0058] Two spray bars 41 are rotatably connected to the housing 1, and a linkage assembly 42 is disposed between the two spray bars 41. The other end of the drive roller 21 and one end of the spray bar 41 pass through the inner wall of the housing 1, and the transmission assembly 43 is connected to the other end of the drive roller 21 and one end of the spray bar 41, respectively.

[0059] The other end of the spray bar 41 penetrates the inner wall of the housing 1. Two rotary connectors 44 are respectively installed on the other end of the corresponding spray bar 41. The solvent circulation supply 46 is connected to the connecting pipe 45 and the pipe body 47 respectively. One end of the connecting pipe 45 is connected to the two rotary connectors 44. One end of the pipe body 47 penetrates the outer wall of the housing 1. The pipe body 47 is connected to the cleaning solvent 15.

[0060] It should be noted that the solvent circulation supply 46 described in this embodiment can provide cleaning solvent 15 to the inside of the spray bar 41, and can also extract the cleaning solvent 15 from the bottom of the second chamber 14 for processing, so as to separate the rolling oil in the cleaning solvent 15, so that the cleaning solvent 15 can be recycled, thereby achieving the purpose of saving costs.

[0061] Specifically, during the operation of the spraying mechanism 4, the solvent circulation supply 46 provides cleaning solvent 15 to the interior of the two spray bars 41. The cleaning solvent 15 is sprayed out under high pressure, degreasing and cleaning the aluminum strip in the first space 31 and the second space 32. At the same time, the drive roller 21 drives one spray bar 41 to rotate, and under the action of the transmission assembly 43, the other spray bar 41 rotates in the opposite direction, thereby creating a counter-current cleaning effect on the aluminum strip.

[0062] In summary, the aluminum strip rolling apparatus of this application embodiment forms a first space and a second space with a triangular structure inside the second chamber under the action of multiple rollers. In the two spaces, the spray mechanism can perform multiple cleanings on the surface of the aluminum strip by rotating. In addition, the reflection effect of the triangular space further increases the cleaning frequency of the aluminum strip surface and reduces the residue of rolling oil on the surface of the aluminum strip, thereby ensuring the product quality of the aluminum strip after heat treatment.
