Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy thin plate processing technology, and in particular to an aluminum alloy thin plate positioning and bending device. Background Technology

[0002] Aluminum alloy sheet is a type of sheet material made primarily of aluminum through processes such as rolling and embossing. It is widely used in various fields, including building exterior walls, ceilings, and curtain walls (e.g., aluminum composite panels, aluminum single panels), which are not only aesthetically pleasing but also waterproof, moisture-proof, and fireproof. It is also used to manufacture electronic product casings, heat sinks, circuit boards, and other components. Utilizing its excellent electrical and thermal conductivity, as well as its lightweight nature, it is used to make mechanical parts and equipment housings, reducing equipment weight and improving operating efficiency. In the packaging industry, aluminum foil and sheet are commonly used as inner or outer layers in pharmaceutical and food packaging materials for preservation, moisture protection, and light blocking. In summary, aluminum alloy sheet, with its unique performance advantages, occupies an indispensable position in many industrial sectors. With continuous technological advancements and increasing market demand, the production process of aluminum alloy sheet will become more sophisticated, and its performance will continue to improve. In the future, it will continue to provide higher quality and more efficient material solutions for various industries, helping modern industry achieve a greener and smarter development goal. When aluminum alloy sheets are processed, they need to go through multiple processes to form a finished product. Bending is a shaping stage, such as single-sided bending and double-sided equidistant bending.

[0003] Currently, when performing equidistant bending on both sides, the thin plate is placed on a worktable and pressed down. Then, a cylinder is activated to drive a pressure plate to bend one side of the thin plate. After bending, the other side is bent to form a U-shaped structure, thus completing the bending process. Although this method can be used to bend U-shaped thin plates, it also has the following drawbacks: because it requires two disassembly and assembly operations to complete the equidistant bending process on both sides, the processing efficiency is low and the processing operation is complicated.

[0004] Therefore, it is necessary to provide an aluminum alloy sheet positioning and bending device to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides an aluminum alloy thin plate positioning and bending device to solve the problem that the existing device requires two disassembly and assembly operations to complete the double-sided equidistant bending process, resulting in low processing efficiency and complicated processing operation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A positioning and bending device for aluminum alloy sheet includes: a worktable, a placement table, a mounting frame, and a bending mechanism;

[0008] The workbench has a placement platform mounted on its top surface, and an mounting frame mounted on the outer side of the placement platform. The mounting frame is a gantry structure, and the placement platform is a T-shaped structure. A baffle is mounted on the top right side of the placement platform, and a limit plate is mounted on the top left side of the placement platform. The limit plate is magnetically connected to the placement platform. A bending mechanism is mounted in the middle of the inner top surface of the mounting frame. The bending mechanism consists of a cylinder, a connecting plate, and a mounting plate. The cylinder is connected to the connecting plate via a push rod. Mounting plates are mounted on both sides of the connecting plate, and the cross-section of the connecting plate and the mounting plate is a U-shaped structure.

[0009] In one embodiment, a spring telescopic rod is installed at the center of the bottom surface of the connecting plate, and a pressure plate is installed at the bottom telescopic end of the spring telescopic rod. The pressure plate is positioned below the mounting plate.

[0010] In one embodiment, an anti-slip pad is installed on the bottom surface of the pressure plate, and the anti-slip pad is composed of multiple coaxial circular rubber strips.

[0011] In one embodiment, the bottom surface of the mounting plate has an insertion port, the outer wall of the insertion port has mounting holes spaced apart, a bending plate is installed in the insertion port, the upper part of the bending plate has a rectangular structure, the bottom part has a semi-circular structure, the side of the bending plate has fixing holes, and multiple bending plates are arranged at intervals, and multiple bending plates together form a bending whole.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model involves placing a thin plate on the top surface of a placement platform, with its right end abutting against the inner side of a baffle. A moving limiting plate limits the left side of the thin plate. A starting cylinder drives the connecting plate and mounting plate downwards, performing a bending operation on both sides of the thin plate. The cylinder also drives the connecting plate and mounting plate downwards, simultaneously driving the spring telescopic rod and pressure plate downwards, so that the bottom surface of the pressure plate preferentially abuts against the top surface of the thin plate. The spring telescopic rod compensates for the descent distance of the mounting plates on both sides, making the thin plate more stable during bending.

[0014] This utility model fixes several bending plates by sequentially placing them into the insertion port and inserting fixing bolts into the fixing holes and mounting holes. With the small unit bending plate setting, when one part is damaged, only the damaged part needs to be replaced to continue using the device, thereby reducing the maintenance cost of the equipment, improving the practical performance of the aluminum alloy plate bending device, and optimizing maintenance costs.

Detailed Implementation

[0019] 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.

[0020] like Figures 1-2 As shown, the present invention provides an aluminum alloy sheet positioning and bending device, comprising: a workbench 1, a placement table 2, a mounting frame 3, and a bending mechanism 4.

[0021] like Figures 1-3 As shown, a placement platform 2 is installed on the top surface of the workbench 1, and a mounting frame 3 is installed on the outer side of the placement platform 2. The mounting frame 3 is a gantry frame structure, and the placement platform 2 is a T-shaped structure. A baffle 21 is installed on the right side of its top, and a limiting plate 22 is installed on the left side of the top surface of the placement platform 2. The limiting plate 22 is magnetically connected to the placement platform 2. A bending mechanism 4 is installed in the middle of the inner top surface of the mounting frame 3. The main body of the bending mechanism 4 consists of a cylinder 41 and a connecting plate 4. 2. The mounting plate 43 is composed of a cylinder 41 connected to a connecting plate 42 via a push rod. Mounting plates 43 are installed on both sides of the connecting plate 42. The cross-section of the connecting plate 42 and the mounting plate 43 is U-shaped. During operation, the thin plate is placed on the top surface of the placement platform 2, with its right end abutting against the inner side of the baffle 21. The left side of the thin plate is limited by the moving limiting plate 22. The connecting plate 42 and the mounting plate 43 are moved downward by starting the cylinder 41, and the two sides of the thin plate are bent.

[0022] Preferably, in one embodiment, such as Figure 3As shown, a spring telescopic rod 47 is installed at the center of the bottom surface of the connecting plate 42. A pressure plate 48 is installed at the bottom telescopic end of the spring telescopic rod 47. The pressure plate 48 is positioned below the mounting plate 43. During operation, the cylinder 41 drives the connecting plate 42 and the mounting plate 43 to move downwards, simultaneously driving the spring telescopic rod 47 and the pressure plate 48 to move downwards as well. This allows the bottom surface of the pressure plate 48 to first abut against the top surface of the thin plate. The spring telescopic rod 47 compensates for the descent distance of the mounting plates 43 on both sides, resulting in higher stability of the thin plate during bending.

[0023] Preferably, in one embodiment, such as Figure 3 As shown, an anti-slip pad 49 is installed on the bottom surface of the pressure plate 48. The anti-slip pad 49 is composed of multiple coaxial circular rubber strips. The anti-slip pad 49 further improves the stability of thin plate processing.

[0024] Preferably, in one embodiment, such as Figure 3 As shown, the bottom surface of the mounting plate 3 has an insertion port 44, and the outer wall of the insertion port 44 has mounting holes 45 spaced apart. A bending plate 46 is installed inside the insertion port 44. The upper part of the bending plate 46 is a rectangular structure, and the bottom part is a semi-circular structure. The side of the bending plate 46 has fixing holes 46. Multiple bending plates 46 are arranged at intervals, and multiple bending plates 46 together form a bending unit. During operation, several bending plates 46 are sequentially placed into the insertion port 44, and the bending plates 46 are fixed by inserting fixing bolts into the fixing holes 46 and mounting holes 45. By setting up small-unit bending plates 46, when one part is damaged, only the damaged part needs to be replaced to continue using the equipment, thereby reducing the maintenance cost of the equipment, improving the practicality of the aluminum alloy plate bending device, and optimizing maintenance costs.

[0025] Working principle of this utility model:

[0026] During operation, the thin plate is placed on the top surface of the placement platform 2, with its right end abutting against the inner side of the baffle 21. The left side of the thin plate is limited by the moving limit plate 22. The connecting plate 42 and the mounting plate 43 are moved downward by the starting cylinder 41 to perform bending operations on both sides of the thin plate. The connecting plate 42 and the mounting plate 43 are moved downward by the cylinder 41, and the spring telescopic rod 47 and the pressure plate 48 are moved downward simultaneously, so that the bottom surface of the pressure plate 48 abuts against the top surface of the thin plate first. The spring telescopic rod 47 compensates for the descent distance of the mounting plates 43 on both sides, making the thin plate more stable during bending. Several bending plates 46 are placed into the insertion slot 44 in sequence, and the bending plates 46 are fixed by inserting the fixing bolts into the fixing holes 46 and the mounting holes 45. With the setting of small unit bending plates 46, when one part is damaged, only the damaged part needs to be replaced to continue using the equipment, thereby reducing the maintenance cost of the equipment, improving the practicality of the aluminum alloy plate bending device, and optimizing maintenance costs.

[0027] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
