Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy thin plate processing, and in particular to a segmented solid solution heat treatment device and process for aluminum alloy thin plates. Background Art

[0002] Aluminum alloy sheets are obtained by hot melting and extrusion to obtain aluminum materials with different cross-sectional shapes. In the traditional production process, aluminum alloys are treated with a single-piece solution treatment. The single-piece solution treatment has low production efficiency, and the disassembly and assembly process is cumbersome. In addition, the piece-by-piece solution treatment makes it difficult to produce a finished product in 20 minutes. At the same time, it increases the risk of surface slippage and the yield rate is low. However, during the processing, the aluminum alloy sheet needs to be straightened. The straightening machine uses external force extrusion to straighten it. However, during the processing, some aluminum profiles with a large degree of curvature are prone to fracture on the inner side of the curved part of the aluminum profile due to the one-time extrusion of the straightening machine, which makes the aluminum profile unable to be used normally, increases the scrap rate of straightening, and increases costs. Summary of the Invention

[0004] In order to solve the above technical problems, the technical solution provided by the present invention is: a segmented solid solution heat treatment equipment for aluminum alloy thin plates, including a uncoiler, a cleaning device, a heating machine, a water cooling device, a straightening device, and a film laminating machine. The uncoiler is arranged on one side of the cleaning device, and the heating machine is arranged on the other side of the cleaning device. A water cooling device is provided on one side of the straightening device, and a film laminating machine is provided on the other side. The water cooling device is arranged between the straightening device and the heating machine. The straightening device includes a lower support frame and an upper support frame.

The bottom of the inner cavity of the water cooling box is provided with multiple second tensioning wheels and third rollers arranged alternately with each other, and the water cooling box is filled with antifreeze liquid b.

[0007] Furthermore, the collar is movably connected to the roller.

[0008] The present invention further discloses a process for a segmented solid solution heat treatment device for aluminum alloy thin plates, which specifically includes the following process steps:

[0009] 1) Unwind the aluminum alloy sheet through an uncoiler;

[0010] 2) The unfolded aluminum alloy sheet passes through the cleaning tank for cleaning, and the stains and water stains on the aluminum alloy sheet are cleaned by a roller brush;

[0011] 3) The clean aluminum alloy sheet enters the heating machine for heating;

[0012] 4) The heated aluminum alloy sheet enters the water cooling device for rapid cooling. By arranging multiple staggered second tensioning wheels and third rollers in the water cooling box, the contact area between the aluminum alloy sheet and the antifreeze liquid B is increased, thereby accelerating the cooling speed of the aluminum alloy sheet.

At this time, the first lower pressing roller is forced to squeeze the compression spring, and the compression spring gives the first lower pressing roller an opposite tension. The tension of the compression spring gives the aluminum alloy sheet a straightening force in the vertical direction, and the raised parts on the aluminum alloy sheet are squeezed and flattened by multiple first lower pressing rollers;

[0015] 7) The straightened aluminum alloy sheet enters the film laminating machine for film laminating treatment;

[0016] 8) Aluminum alloy sheets are divided into finished products.

[0017] After adopting the above structure, the present invention has the following advantages:

[0018] 1. The aluminum alloy sheet goes through uncoiling, cleaning, heating, water cooling, straightening, unrolling and laminating to finished product. Through uninterrupted continuous production, without disassembly and material transfer, the production efficiency is greatly improved, ensuring that the aluminum alloy sheet is quickly completed within 20 minutes from solution furnace to finished product, thereby improving the yield rate of aluminum alloy sheet.

[0019] 2. By arranging a second lower pressure roller staggered with the conveying roller in the upper support frame, longitudinal tension and transverse pulling force are applied to the aluminum alloy sheet entering the straightening device at the same time, thereby achieving the bending and straightening effect of the aluminum alloy sheet, and the second lower pressure roller cooperates with the conveying roller to make the aluminum alloy sheet bend repeatedly in the forward and reverse directions, eliminating the internal stress of the aluminum alloy sheet and improving the production quality of the product; at the same time, the movable first lower pressure roller is arranged in parallel with the conveying roller, and a vertical straightening force is applied to the aluminum alloy sheet synchronously, and the protrusions on the aluminum alloy sheet are squeezed and flattened by multiple first lower pressure rollers, thereby improving the straightening quality of the aluminum alloy sheet and avoiding the breakage of the aluminum alloy sheet.

[0031] Specifically, the collar 512 is movably connected to the roller 510 .

[0032] The present invention more specifically discloses a process for a segmented solid solution heat treatment equipment for aluminum alloy thin plates, which specifically includes the following process steps:

[0033] 1) Unwinding the aluminum alloy sheet through an uncoiler 1;

[0034] 2) The unfolded aluminum alloy sheet passes through the cleaning tank 201 for cleaning, and the dirt and water stains on the aluminum alloy sheet are cleaned by the roller brush 204;

[0035] 3) The cleaned aluminum alloy sheet enters the heating machine 3 for heating;

[0036] 4) The heated aluminum alloy sheet enters the water cooling device 4 for rapid cooling. By providing a plurality of staggered second tensioning wheels 403 and third rollers 404 in the water cooling box 401, the contact area between the aluminum alloy sheet and the antifreeze liquid b405 is increased, thereby accelerating the cooling rate of the aluminum alloy sheet.

[0037] 5) The cooled aluminum alloy sheet enters the straightening device 5 for straightening. The motor 505 is started to drive the conveying roller 504 to rotate. At the same time, the output end of the hydraulic cylinder 503 is controlled to retract, driving the upper support frame 502 to move downward. The second lower pressing roller 514 and the conveying roller 504 are staggered with each other. When the aluminum alloy sheet passes through the second lower pressing roller 514, a longitudinal tension and a transverse pulling force are simultaneously applied to the aluminum alloy sheet, which plays a role in leveling. At the same time, the second lower pressing roller 514 drives the aluminum alloy sheet to repeatedly bend forward and backward, eliminating the internal stress of the aluminum alloy sheet.

[0038] 6) At the same time, the first lower pressing roller 509 is driven by the hydraulic cylinder 503 to synchronously move downward to extrude the aluminum alloy sheet. At this time, the first lower pressing roller 509 is forced to squeeze the compression spring 513. At the same time, the compression spring 513 gives the first lower pressing roller 509 an opposite tension. The tension of the compression spring 513 gives the aluminum alloy sheet a straightening force in the vertical direction. The raised parts on the aluminum alloy sheet are squeezed and flattened by multiple first lower pressing rollers 509, thereby improving the straightening quality of the aluminum alloy sheet and avoiding the aluminum alloy sheet from breaking during one straightening.

[0039] 7) The straightened aluminum alloy sheet enters the film laminating machine 6 for film laminating processing;

[0040] 8) Split and form aluminum alloy sheets.

[0041] The working principle of the present invention is as follows: when in use, the uncoiler is started to unwind the aluminum alloy sheet and pass it around the first roller, the first tensioning wheel and the roller brush on the cleaning device. The driving motor drives the roller brush to rotate to clean the stains and water stains on the aluminum alloy sheet. Then the aluminum alloy sheet enters the heating machine for heating. The heated aluminum alloy sheet enters the water cooling device for cooling. The aluminum alloy sheet passes around the second roller, the second tensioning wheel and the third roller to increase the cooling area of the aluminum alloy sheet. The cooled aluminum alloy sheet enters the straightening device. Inside, start the motor and hydraulic cylinder, the motor drives the conveyor roller to rotate through the chain, and at the same time the hydraulic cylinder drives the upper support frame to move downward, driving the first lower pressing roller and the second lower pressing roller to press the aluminum alloy sheet. The aluminum alloy sheet is first subjected to the longitudinal tension and transverse pulling force of the first lower pressing roller, which stretches the aluminum alloy sheet flat. Then, the second lower pressing roller gives the aluminum alloy sheet a vertical straightening force under the tension of the compression spring, pressing the aluminum alloy sheet flat. The flattened aluminum alloy sheet enters the film laminating machine for film laminating processing, and finally is cut into finished products.

[0042] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
