Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold rolling mill technology, specifically to a cold rolling equipment for aluminum strip processing. Background Technology
[0002] Cold rolling uses hot-rolled coils as raw materials. After pickling to remove the oxide scale, the coils are continuously cold-rolled. The continuous cold deformation causes work hardening, which increases the strength and hardness of the coil material. The mechanical properties of the coil material are then restored through an annealing process.
[0003] Cold rolling production relies heavily on cold rolling rolls. In certain high-quality aluminum strip processing applications, new rolls must be replaced before each operation to ensure the roll surface is free of adhesion and wear, and that the light transmittance meets standards. Slow rolling is also necessary at the beginning of cold rolling to confirm rolling quality; if problems are found, the rolls must be replaced promptly. Therefore, the efficiency of cold rolling roll assembly and disassembly affects cold rolling efficiency. Current technology for replacing cold rolling rolls is quite cumbersome, requiring the complete disassembly of the cold rolling mill, followed by the removal of the bearing housings at both ends of the cold rolling rolls, before the roll replacement can be performed. The overall operation is time-consuming. Utility Model Content
[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects of cumbersome disassembly and assembly in the prior art, thereby providing a cold rolling equipment for aluminum strip processing and production.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A cold rolling equipment for aluminum strip processing includes an uncoiling device, a cold rolling device, an annealing device, and a winding device arranged sequentially along the production process. The uncoiling device includes an uncoiling frame, an uncoiling roller, and an uncoiling drive. The axis of the uncoiling roller is arranged along the length of the uncoiling frame and is rotatably mounted on the uncoiling frame. The uncoiling drive controls the rotation of the uncoiling roller. Multiple sets of guide rollers are arranged between the uncoiling device and the cold rolling device. The guide rollers in the same set are arranged side by side vertically, and the axis of the guide roller is parallel to the axis of the uncoiling roller. The cold rolling device includes an upper roller, a lower roller, and a lifting frame. The upper roller and the lower roller are both mounted on the lifting frame. The winding device includes a winding frame, a winding roller, and a winding drive.

[0007] By adopting the above technical solution, the cold rolling roll is divided into an adjustable gap upper and lower roll system and the upper and lower roll components are modularly designed. The cold rolling roll and bearing form corresponding upper and lower roll modules in advance. When the cold rolling roll needs to be replaced, it can be replaced directly and quickly, which is convenient for operation. After hoisting and fixing, it can be put into use directly. It is convenient to adjust the cold rolling roll according to the cold rolling quality and ensure high-quality production.

The movable frame is installed above the fixed frame and its movement is controlled by the lifting drive component.
[0009] By adopting the above technical solution, the upper and lower roller components are separated into individual modules. When replacement is needed, a single module can be disassembled and replaced directly. The roller surface, bearings, and connecting structures are then inspected, which improves the efficiency of replacement and disassembly and effectively reduces replacement time. The distance between the upper and lower modules can also be adjusted by the distance between the movable frame and the fixed frame, thereby adjusting the vertical spacing of the rollers.
[0010] Furthermore, each upper roller module includes two upper mounting seats, an upper roller shaft, an upper roller cylinder, and two sets of upper bearings. The two ends of the upper roller shaft are rotatably mounted in the two upper mounting seats. The axis of the upper roller shaft is set along the width direction of the lifting frame. The upper roller cylinder is coaxial with the upper roller shaft and sleeved on the upper roller shaft. The diameter of the upper roller cylinder is greater than the width of the front side of the upper mounting seat, and the length of the upper roller cylinder is less than the length of the upper roller shaft. The upper bearings are respectively installed in the upper mounting seats and sleeved on both ends of the upper roller shaft. Each upper mounting seat has an upper mounting plate extending outward from both ends of its bottom. Each upper mounting plate has an oblong upper mounting hole. A set of lifting lugs is symmetrically arranged on the top of the upper mounting seat.
[0011] By adopting the above technical solution, the upper mounting base, upper roller shaft, upper roller and upper bearing are pre-assembled into an upper roller module. The upper roller is sleeved on the upper roller shaft, and two sets of upper bearings are sleeved at both ends of the upper roller shaft and installed in the upper mounting base. Each set of upper bearings includes a thrust bearing and a rolling mill bearing to ensure stable support at the end of the roller shaft, thereby making the rotation process smooth. The top lifting lugs facilitate the hoisting of the upper mounting base.
[0012] Furthermore, each of the lower roller modules includes two lower mounting seats, a lower roller shaft, a lower roller cylinder, and two sets of lower bearings. The two ends of the lower roller shaft are rotatably mounted in the two lower mounting seats. The axis of the lower roller shaft is set along the width direction of the lifting frame. The lower roller cylinder is coaxially arranged with the lower roller shaft and sleeved on the lower roller shaft. The diameter of the lower roller cylinder is greater than the width of the front side of the lower mounting seat, and the length of the lower roller cylinder is less than the length of the lower roller shaft. The lower bearings are respectively installed in the lower mounting seats and sleeved on both ends of the lower roller shaft. The two ends of the top of the lower mounting seat have lower mounting plates extending outward. Each lower mounting plate has a waist-shaped lower mounting hole. The bottom of the lower mounting seat is arc-shaped, and a set of lifting lugs are symmetrically arranged on the sides of the two lower mounting seats that are far apart from each other.
[0013] By adopting the above technical solution, the lower mounting base, lower roller shaft, lower roller, and lower bearing are pre-assembled into a lower roller module. The lower roller is sleeved on the lower roller shaft, and two sets of lower bearings are sleeved at both ends of the lower roller shaft and installed in the lower mounting base. Each set of lower bearings includes a thrust bearing and a rolling mill bearing, ensuring stable support at the end of the roller shaft, thereby enabling smooth rotation. The side lifting lugs facilitate the lifting of the lower mounting base onto the installation trolley, which is then pushed by the installation trolley to the bottom of the fixed frame for installation.
[0014] Furthermore, the lifting drive component is installed between two adjacent lower roller modules, and the fixed frame has a movable hole corresponding to the output shaft of the lifting drive component, and the output shaft of the lifting drive component is fixed to the movable frame; the top surface of the movable frame has an upper fixing hole corresponding to the upper mounting hole, and the bottom surface of the top of the fixed frame has a lower fixing hole corresponding to the lower mounting hole.
[0015] By adopting the above technical solution, the upper mounting plate installs the upper mounting seat on the movable frame, and the lower mounting plate installs the lower mounting seat on the fixed frame. The upper fixing hole and the upper mounting hole, and the lower fixing hole and the lower mounting hole are connected by the waist-shaped hole and the round hole, which not only achieves fixation but also facilitates the adjustment of the roller spacing between the same row.
[0016] Furthermore, two edge-cutting components are provided between the cold rolling unit and the annealing unit. The two edge-cutting components are installed on opposite sides of the width direction of the cold rolling unit and on the lifting frame. Each edge-cutting component includes a pressure plate, a slitting circular knife, and a slitting drive. The slitting circular knife is coaxially arranged with the pressure plate, and the slitting drive controls the pressure plate and the slitting circular knife to move synchronously.
[0017] By adopting the above technical solution, the two sides of the aluminum strip are cut off after cold rolling to reduce side defects. The cutting round knife and the pressing plate work together to complete the side cutting operation.
[0018] Furthermore, a receiving component is provided between the trimming component and the annealing device. The receiving component includes a receiving shaft, a receiving frame, and a receiving drive. The receiving shaft is rotatably mounted on the receiving frame and controlled by the receiving drive. A cutting component is provided at one end of the receiving component near the annealing device. The cutting component includes a cutting blade, a receiving frame, and two pressure plates. The cutting blade and pressure plates are both arranged along the axis of the receiving shaft. The cutting blade and pressure plates are both raised and lowered above the receiving frame, and the pressure plates are arranged opposite each other on both sides of the cutting blade.
[0019] By adopting the above technical solution, the cold-rolled aluminum strip is temporarily wound up by the take-up piece and undergoes cooling and tension adjustment operations for several natural days on the take-up piece. After the take-up piece takes up the material, two steel strips are wrapped around the outside to tighten it. The head and tail of the aluminum strip are not cut off before take-up. The coil is cut off during subsequent annealing. The cutting knife, pressure plate and receiving frame work together to achieve longitudinal cutting of the aluminum strip.
[0020] Furthermore, the receiving frame is also provided with a pusher, which includes a pusher plate and a pusher drive, the pusher drive controlling the pusher plate to move along the receiving shaft axis; the receiving frame is also equipped with a pressing block, the pressing block being lifted and lowered on the receiving frame.
[0021] By adopting the above technical solution, the aluminum strip that has been cut off after cutting is pushed out by the pusher, which does not affect the subsequent conveying of aluminum strip; the pressure block always presses on the strip wound by the take-up shaft and rises continuously with the strip, which makes it easy to control the tension of the strip on the take-up frame.
[0022] In summary, the technical solution of this utility model has the following advantages:
[0023] 1. The cold rolling equipment for aluminum strip processing provided by this utility model divides the cold rolling roll into an adjustable gap upper and lower roll system and modularly designs the upper and lower roll components.

Detailed Implementation
[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.
[0032] A cold rolling equipment for aluminum strip processing, such as Figure 1As shown, the assembly includes, from left to right, an unwinding device 1, a cold rolling device 2, an annealing device 6, and a winding device 7. These components are arranged sequentially along the production process. The unwinding device 1 includes an unwinding frame 11, an unwinding roller 12, and an unwinding drive 13. The unwinding roller 12 has its axis along the length of the unwinding frame 11 and is rotatably mounted on it. The unwinding drive 13 controls the rotation of the unwinding roller 12. Multiple sets of guide rollers are arranged between the unwinding device 1 and the cold rolling device 2. 14. Guide rollers 14 in the same group are arranged side by side, with the axis of guide rollers 14 parallel to the axis of unwinding roller 12. Cold rolling device 2 includes upper roller 3, lower roller 4, and lifting frame 5. Upper roller 3 and lower roller 4 are both mounted on lifting frame 5. Annealing device 6 is an existing annealing furnace. Winding device 7 includes winding frame 71, winding roller 72, and winding drive 73. The axis of winding roller 72 is arranged along the length of winding frame 71 and is rotatably mounted on winding frame 71. Winding drive 73 controls the rotation of winding roller 72. The cold rolling roll is divided into an adjustable-pitch upper and lower roller system, and the upper roller 3 and lower roller 4 are modularly designed. The cold rolling roll and bearing can be pre-assembled to form corresponding upper roller module 31 and lower roller module 41. When the cold rolling roll needs to be replaced, it can be quickly replaced directly for easy operation. After hoisting and fixing, it can be put into use directly. It is convenient to adjust the cold rolling roll according to the cold rolling quality to ensure high-quality production.
[0033] like Figure 1 and Figure 2 As shown, the upper roller assembly 3 includes multiple upper roller modules 31 arranged in an array along the length of the lifting frame 5. The upper roller modules 31 are arranged along the width of the lifting frame 5, and the bottom of the upper roller modules 31 is fixed to the lifting frame 5 with bolts. The lower roller assembly 4 includes multiple lower roller modules 41 arranged in an array along the length of the lifting frame 5. The lower roller modules 41 are arranged corresponding to the upper roller modules 31. The lower roller modules 41 are arranged along the width of the lifting frame 5, and the top of the lower roller modules 41 is fixed to the lifting frame 5 with bolts. The upper roller assembly 3 and the lower roller assembly 4 are separated into individual modules. When replacement is needed, a single module can be disassembled and replaced directly. The roller surface, bearings and connecting structures can then be inspected, which improves the efficiency of replacement and disassembly and effectively reduces the replacement time. Individual drive components can be directly assembled on the upper roll module 31 and the lower roll module 41. The drive components are not shown in the figure. After installing the upper roll module 31 and the lower roll module 41, the cold rolling unit 2 can be started directly for cold rolling operation. Alternatively, chain drive can be used to link the corresponding upper roll module 31 and lower roll module 41 together, which can be operated in a single group. Although it is more complicated than driving each individual group, the driving between single groups is still simpler than the existing technology.
[0034] Each upper roller module 31 includes two upper mounting seats 311, an upper roller shaft 312, an upper roller 313, and two sets of upper bearings 314. The upper roller shaft 312 is rotatably mounted in the two upper mounting seats 311 at both ends. The axis of the upper roller shaft 312 is set along the width direction of the lifting frame 5. The upper roller 313 is coaxially set with the upper roller shaft 312 and sleeved on the upper roller shaft 312. The diameter of the upper roller 313 is greater than the width of the front side of the upper mounting seat 311 and the length of the upper roller 313 is less than the length of the upper roller shaft 312. The front side of the upper mounting seat 311 is square. The upper bearings 314 are respectively installed in the upper mounting seat 311 and sleeved on both ends of the upper roller shaft 312. The upper mounting base 311, upper roller shaft 312, upper roller 313 and upper bearing 314 are pre-assembled into an upper roller module 31. The upper roller 313 is sleeved on the upper roller shaft 312. Two sets of upper bearings 314 are sleeved at both ends of the upper roller shaft 312 and installed in the upper mounting base 311. Each set of upper bearings 314 includes a thrust bearing and a mill bearing to ensure stable support at the end of the roller shaft, thereby ensuring smooth rotation.
[0035] Each lower roller module 41 includes two lower mounting seats 411, a lower roller shaft 412, a lower roller 413, and two sets of lower bearings 414. The two ends of the lower roller shaft 412 are rotatably mounted in the two lower mounting seats 411. The axis of the lower roller shaft 412 is set along the width direction of the lifting frame 5. The lower roller 413 is coaxially set with the lower roller shaft 412 and sleeved on the lower roller shaft 412. The diameter of the lower roller 413 is greater than the width of the front side of the lower mounting seat 411 and the length of the lower roller 413 is less than the length of the lower roller shaft 412. The front side of the lower mounting seat 411 is a rectangle with an arc edge at the bottom. The lower bearings 414 are respectively installed in the lower mounting seats 411 and sleeved on both ends of the lower roller shaft 412. The lower mounting base 411, lower roller shaft 412, lower roller 413 and lower bearing 414 are pre-assembled into a lower roller module 41. The lower roller 413 is sleeved on the lower roller shaft 412. Two sets of lower bearings 414 are sleeved at both ends of the lower roller shaft 412 and installed in the lower mounting base 411. Each set of lower bearings 414 includes a thrust bearing and a mill bearing to ensure stable support at the end of the roller shaft, thereby ensuring smooth rotation.
[0036] The lifting frame 5 includes a fixed frame 51, a movable frame 52, and a lifting drive component 53. The movable frame 52 is mounted above the fixed frame 51 and its movement is controlled by the lifting drive component 53. The output shaft of the lifting drive component 53 is fixed to the movable frame 52. The lifting drive component 53 is installed between two adjacent lower roller modules 41, and the fixed frame 51 has a movable hole 512 corresponding to the output shaft of the lifting drive component 53. The distance between the upper and lower modules can also be adjusted by the distance between the movable frame 52 and the fixed frame 51, thereby adjusting the vertical spacing of the rollers. When the fixed frame 51 and the movable frame 52 are in contact, the distance between the upper and lower rollers is less than the thickness of the aluminum strip to be cold-rolled.
[0037] Each upper mounting base 311 has an upper mounting plate 3111 extending outward from both ends of its bottom. The upper mounting plate 3111 has a waist-shaped upper mounting hole 31111. The lower mounting base 411 has a lower mounting plate 4111 extending outward from both ends of its top. The lower mounting plate 4111 has a waist-shaped lower mounting hole 41111. The top side of the movable frame 52 has an upper fixing hole 521 corresponding to the upper mounting hole 31111, and the bottom of the top side of the fixed frame 51 has a lower fixing hole 511 corresponding to the lower mounting hole 41111. The upper mounting plate 3111 mounts the upper mounting base 3111 onto the movable frame 52, and the lower mounting plate 4111 mounts the lower mounting base 4111 onto the fixed frame 51. The upper fixing hole 521 connects to the upper mounting hole 31111, and the lower fixing hole 511 connects to the lower mounting hole 41111, through a waist-shaped hole and a round hole. This connection achieves fixation while also facilitating adjustment of the roller spacing between rollers in the same row.
[0038] A set of lifting lugs 21 are symmetrically arranged on the top of the upper mounting base 311. A set of lifting lugs 21 are symmetrically arranged on the sides of the lower mounting base 411, which are arc-shaped at the bottom and far apart from each other. The top lifting lugs 21 facilitate the hoisting of the upper mounting base 311, and the side lifting lugs 21 facilitate the hoisting of the lower mounting base 411 onto the installation trolley, which is then pushed by the installation trolley to the bottom of the fixing frame 51 for installation.
[0039] like Figure 1 , Figure 2 and Figure 3 As shown, two edge-cutting components 8 are also provided between the cold rolling unit 2 and the annealing unit 6. The two edge-cutting components 8 are respectively installed on opposite sides of the cold rolling unit 2 in the width direction and mounted on the lifting frame 5. Each edge-cutting component 8 includes a pressure plate 81, a slitting circular knife 82, and a slitting drive 83. The slitting circular knife 82 is coaxially arranged with the pressure plate 81, and the slitting drive 83 controls the synchronous movement of the pressure plate 81 and the slitting circular knife 82. After the aluminum strip is cold-rolled, the two sides of the aluminum strip are trimmed to reduce side defects. The slitting circular knife 82 and the pressure plate 81 cooperate to complete the side trimming operation. The distance between the pressure plates 81 is adjustable, and a guide frame for receiving the aluminum strip output is provided at the right end of the fixing frame 51.
[0040] like Figure 1 , Figure 2 and Figure 3As shown, a take-up piece 9 is also provided between the trimming part 8 and the annealing device 6. The take-up piece 9 includes a take-up shaft 91, a take-up frame 92, and a take-up drive 93. The take-up shaft 91 is rotatably mounted on the take-up frame 92 and controlled by the take-up drive 93. The cold-rolled aluminum strip is temporarily wound up through the take-up piece 9 and undergoes cooling and tension adjustment operations for several natural days on the take-up piece 9. After the take-up piece 9 takes up the strip, two steel strips are wrapped around its outer side to tighten it. A pressure block 921 is also installed on the take-up frame 92. The pressure block 921 is elliptical and mounted on the take-up frame 92. The pressure block 921 always presses on the strip wound by the take-up shaft 91 and rises continuously with the strip, which facilitates control of the tension of the strip on the take-up frame 92.
[0041] A cutting element 10 is provided at one end of the take-up piece 9 near the annealing device 6. The cutting element 10 includes a cutting blade 101, a receiving frame 102, and two pressure plates 103. The cutting blade 101 and the pressure plates 103 are both arranged along the axis of the take-up shaft 91. The cutting blade 101 and the pressure plates 103 are both raised and lowered above the receiving frame 102, with the pressure plates 103 positioned opposite each other on both sides of the cutting blade 101. The head and tail of the aluminum strip are not cut off before take-up; the strip is cut off during subsequent annealing. The cutting blade 101, pressure plates 103, and receiving frame 102 work together to achieve longitudinal cutting of the aluminum strip. This simplifies the cutting structure by providing only one cutting element 10 at the take-up piece 9. This allows for the cutting of the head defect portion—the test section during slow rolling—at the same cutting element 10 after the coil has been cold rolled, as well as the cutting of the tail defect portion during the contact stage of cold rolling, ensuring the quality of the finished coil.
[0042] The receiving frame 102 is also equipped with a pusher 1021, which includes a pusher plate 10211 and a pusher drive 10212. The pusher drive 10212 controls the pusher plate 10211 to move along the axis of the receiving shaft 91. The aluminum strip that has been cut off after cutting is pushed off by the pusher 1021 without affecting the subsequent conveying of aluminum strip.
[0043] The working principle and usage of this cold rolling equipment for aluminum strip processing and production: The cold rolling unit 2 is divided into upper and lower roll systems with adjustable spacing. The upper roll module 31 and the lower roll module 41 are pre-assembled, and the corresponding drive components are prepared. Before the cold rolling operation, the appropriate upper roll module 31 and lower roll module 41 are selected and assembled. The upper mounting base 311 is hoisted and fixed to the movable frame 52. Then, the lower mounting base 411 is installed on the trolley and fixed to the fixed frame 51. After that, the distance between the upper roll module 31 and the lower roll module 41 is adjusted.
[0044] In the cold rolling operation of aluminum strip coils, the cold rolling rolls are easy to disassemble and assemble. At the beginning of cold rolling, the operation is slow to check the roll surface and cold rolling quality. The slow rolling section is checked and the rolling surface is monitored in a timely manner. If there are defects on the rolling surface, the rolls are replaced in time. After cold rolling, the aluminum strip is trimmed by the trimming piece 8. Then the aluminum strip is temporarily wound on the take-up piece 9. Before winding, the defective parts at the head of the coil and the defective parts at the tail of the end of cold rolling are cut off. After winding, the coil is pressed and two steel strips are wrapped around the outside of the aluminum strip coil for tension adjustment. After cooling for several natural days and tension adjustment, it is sent to the annealing device 6 for annealing. After annealing, the material is discharged. It is determined whether the material needs to be trimmed and wound again according to the condition of the coil surface.
