Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy thin plate processing equipment, and in particular to an aluminum alloy thin plate flattening and forming device. Background Technology

[0002] Aluminum alloys are alloys based on aluminum with added amounts of other alloying elements, and are one type of lightweight metal material. They can be broadly classified into two categories according to composition and processing methods: wrought aluminum alloys and cast aluminum alloys. Wrought aluminum alloys are manufactured into various plastically processed products through rolling, extrusion, stretching, forging, and other methods; cast aluminum alloys are produced by directly casting various parts into blanks using sand molds, iron molds, investment casting, and die casting methods after the raw materials have been melted. Aluminum alloy sheets are generally rolled into thin sheets through hot rolling, cold rolling, and other processes.

[0003] A document with publication number CN220515044U discloses a cold rolling mill, including a cold rolling mill shell. Four rotating shafts are rotatably connected to the inner wall of the cold rolling mill shell. Each shaft extends beyond the side wall of the cold rolling mill shell at both ends. Guide wheels are fixedly connected to the outer side walls of the two left-hand shafts, and cold rolling wheels are fixedly connected to the outer side walls of the two right-hand shafts. A mounting plate is fixedly connected to the side wall of the cold rolling mill shell, and a motor is fixedly connected to the upper side of the mounting plate. The output shaft of the motor is fixedly connected to one end of one of the right-hand shafts. Transmission devices are provided at the ends of the two right-hand shafts extending beyond the cold rolling mill shell. A cleaning device is provided on the inner wall of the cold rolling mill shell. Through the cooperation of components such as a water tank, cleaning brush, water pipe, and nozzle, the cold-rolled workpiece can be rinsed, cleaned, and cooled. The rinsed water can be recycled back into the water tank.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0026] Example 1:

[0027] like Figure 1As shown, the aluminum alloy sheet flattening and forming device provided by this utility model includes: a frame 1, on which a traction roller group 2, a multi-stage cold rolling mechanism, and a cleaning and cooling mechanism are installed; the multi-stage cold rolling mechanism includes a first-stage cold rolling roller group 3, a second-stage cold rolling roller group 4, and a third-stage cold rolling roller group 5 installed on the frame 1, each of which consists of multiple cold rolling rollers; the cleaning and cooling mechanism includes two first cleaning rollers 7, two second cleaning rollers 8, and two polishing rollers 9 installed on the frame 1, the first cleaning rollers 7, 8, and 9... The first cleaning roller 7, the second cleaning roller 8, and the polishing roller 9 are all driven by a motor to rotate. The two first cleaning rollers 7 are located between the traction roller group 2 and the first-stage cold rolling roller group 3. The two second cleaning rollers 8 are located between the first-stage cold rolling roller group 3 and the second-stage cold rolling roller group 4. The two polishing rollers 9 are located between the second-stage cold rolling roller group 4 and the third-stage cold rolling roller group 5. An air inlet pipe 10 is installed on one side of the first cleaning roller 7 and the second cleaning roller 8. One end of the air inlet pipe 10 is connected to an industrial air cooler. An industrial vacuum cleaner 11 is installed above and below the two polishing rollers 9. In operation, the hot-rolled aluminum alloy sheet is conveyed to the traction roller group 2, and then fed into the first-stage cold rolling roller group 3. The first-stage cold rolling roller group 3 performs the first cold rolling on the aluminum alloy sheet, reducing its thickness. Similarly, the second-stage cold rolling roller group 4 and the third-stage cold rolling roller group 5 perform the second and third cold rolling on the aluminum alloy sheet, further reducing its thickness and producing a thin aluminum alloy sheet of acceptable thickness. Through this multi-stage cold rolling process, the thickness of the aluminum alloy sheet gradually decreases, making it more suitable for producing thinner aluminum alloy flat sheets. It is worth noting that before entering the first-stage cold rolling roller group 3, the aluminum alloy sheet needs to be air-inleted to the position of the first cleaning roller 7. The two first cleaning rollers 7 clean the top and bottom surfaces of the aluminum alloy sheet, removing debris and impurities. Meanwhile, an industrial air cooler blows cold air from the side onto the top of the aluminum alloy sheet through the air inlet pipe 10. After cold rolling, the aluminum alloy sheet is cooled to a temperature within the cold rolling temperature range, and residual dust on the sheet is blown away. The dust is discharged from the air outlet on the side of the equipment and removed by the dust removal equipment. Similarly, before the aluminum alloy sheet enters the secondary cold rolling roll group 4, the second cleaning roller 8 and the air inlet pipe 10 clean and cool the sheet, effectively reducing the amount of debris adhering to the surface of the aluminum alloy sheet, improving product quality, preventing water stains, reducing the risk of rust, and improving electrical safety. Before entering the tertiary cold rolling roll group 5, the top and bottom of the aluminum alloy sheet are polished by the polishing roller 9, improving the flatness of the sheet. This ensures that the flatness of the aluminum alloy sheet is effectively improved after cold rolling in the tertiary cold rolling roll group 5. Furthermore, the debris generated during polishing is collected by the industrial vacuum cleaner 11, avoiding pollution to the surrounding environment and facilitating the cleaning and maintenance of the factory.

[0028] By setting up frame 1, traction roller group 2, multi-stage cold rolling mechanism and cleaning and cooling mechanism, it is possible to perform multi-stage cold rolling on aluminum alloy plates, which is beneficial for the production of aluminum alloy thin plates. Using air cooling and physical methods to clean and polish aluminum alloy plates can improve the safety of equipment use and improve product quality.

[0029] Example 2:

[0030] like Figure 1 As shown, in this embodiment, a conveyor roller group 6 is installed on the frame 1. The conveyor roller group 6 is located behind the three-stage cold rolling roller group 5. The aluminum alloy sheet cold-rolled by the three-stage cold rolling roller group 5 is sent out of the device through the conveyor roller group 6.

[0031] By installing the conveyor roller group 6 on the frame 1, the cold-rolled aluminum alloy sheet can be easily sent out of the device.

[0032] Example 3:

[0033] like Figure 1 As shown, in this embodiment, a shearing mechanism is provided between the three-stage cold rolling roll group 5 and the conveying roll group 6. The shearing mechanism cuts the aluminum alloy sheet to produce aluminum alloy sheets of the corresponding specifications. The shearing mechanism includes a support platform 12, a punching head 13, and a drive assembly 14. The height of the support platform 12 is fixed. The punching head 13 is connected to the drive assembly 14, and the drive assembly 14 controls the lifting and lowering of the punching head 13. In use, the bottom of the aluminum alloy sheet passes over the top of the support platform 12, and its bottom contacts the top of the support platform 12. Since the sheet movement speed in the cold rolling process is relatively slow, generally not exceeding 0.5m / min to 3m / min, when the sheet moves to the right side of the punching head 3 (near the output roll group 6) and the length reaches the product length design requirement, the punching head 13 is lowered under the drive of the drive assembly 14 to punch and cut the aluminum alloy sheet, thereby producing aluminum alloy sheets of the corresponding length, which facilitates the subsequent production and processing of products.

[0034] By incorporating a support platform 12, a punching head 13, and a drive assembly 14, continuous aluminum alloy sheets can be easily cut, facilitating the processing and production of subsequent products.

[0035] Example 4:

[0036] like Figure 2 As shown, in this embodiment, the support platform 12 includes a support base 15 and a wear-resistant plate 16. The two sides of the support base 15 are fixedly connected to the frame 1. The wear-resistant plate 16 is installed on the top of the support base 15 by bolts 20. The wear-resistant plate 16 is in contact with the aluminum alloy plate. The material properties of the wear-resistant plate 16 make it harder and more wear-resistant, which can effectively extend the overall service life of the support platform 12. When the wear-resistant plate 16 needs to be replaced, only the wear-resistant plate 16 needs to be replaced, which can effectively reduce maintenance costs.

[0037] By setting up a support platform 12 that includes a support base 15 and a wear-resistant plate 16, the maintenance cost of the support platform 12 can be effectively reduced.

[0038] Example 5:

[0039] like Figure 2 As shown, in this embodiment, a buffer pad 17 is installed between the support base 15 and the wear-resistant plate 16. The buffer pad 17 is made of rubber or other materials, which can reduce the impact of the punching head 13 on the wear-resistant plate 16 caused by the overtravel of the punching head 13, thereby facilitating the long-term use of the punching head 13 and the wear-resistant plate 16.

[0040] By installing a buffer pad 17 between the support base 15 and the wear-resistant plate 16, the service life of the punching head 13 can be improved.

[0041] Example 6:

[0042] like Figure 2 As shown, in this embodiment, a positioning groove 18 is provided on the top of the support base 15, and a positioning strip 19 is installed on the bottom of the wear-resistant plate 16. The positioning strip 19 is embedded in the positioning groove 18 to facilitate the assembly between the support base 15 and the wear-resistant plate 16.

[0043] By setting the positioning groove 18 and the positioning strip 19, it is beneficial to assemble and use the support base 15 and the wear-resistant plate 16.

[0044] Example 7:

[0045] like Figure 2 As shown, in this embodiment, a relief groove 21 is provided on the top of the wear-resistant plate 16. The relief groove 21 is aligned with the cutting edge of the punching head 13. When in use, the punching head 13 punches the aluminum alloy sheet downwards, and its cutting edge is inserted into the relief groove 21, which can effectively prevent the cutting edge from breaking.

[0046] By opening a relief groove 21 on the top of the wear-resistant plate 16, the cutting edge of the punching head 13 can be prevented from breaking, thereby improving the service life of the punching head 13.

[0047] Working Principle: During operation, the hot-rolled aluminum alloy sheet is conveyed to the traction roller group 2, and then fed into the first-stage cold rolling roller group 3. The first-stage cold rolling roller group 3 performs the first cold rolling on the aluminum alloy sheet, reducing its thickness. Similarly, the second-stage cold rolling roller group 4 and the third-stage cold rolling roller group 5 perform the second and third cold rolling on the aluminum alloy sheet, further reducing its thickness and producing a qualified aluminum alloy sheet. Through multi-stage cold rolling, the thickness of the aluminum alloy sheet gradually decreases, making it more suitable for the production of thinner aluminum alloy flat sheets. It is worth noting that before entering the first-stage cold rolling roller group 3, the aluminum alloy sheet needs to be air-inleted to the position of the first cleaning roller 7. The two first cleaning rollers 7 clean the top and bottom surfaces of the aluminum alloy sheet, removing debris and impurities. Meanwhile, an industrial air cooler blows cold air from the side onto the top of the aluminum alloy sheet through the air inlet pipe 10, ensuring the cold-rolled sheet... The aluminum alloy sheet is cooled to a temperature within the cold rolling temperature range, and residual dust on the sheet is blown away. The dust is discharged from the air outlet on the side of the equipment and removed by the dust removal equipment. Similarly, before the aluminum alloy sheet enters the secondary cold rolling roll group 4, the second cleaning roller 8 and the air inlet pipe 10 clean and cool the sheet, effectively reducing the amount of debris adhering to the surface of the sheet, improving product quality, and preventing water stains, which is beneficial to product quality, less likely to cause rust on the equipment, and improves electrical safety. Before entering the tertiary cold rolling roll group 5, the top and bottom of the sheet are polished by the polishing roller 9 to improve its flatness. After the sheet is cold rolled by the tertiary cold rolling roll group 5, its flatness is effectively improved. Furthermore, the debris generated during polishing is collected by the industrial vacuum cleaner 11, avoiding pollution to the surrounding environment and facilitating the cleaning and maintenance of the factory.
