Description

Technical Field

[0001] This utility model relates to the technical field of aluminum plate processing equipment, specifically to a bending machine for aluminum plate processing. Background Technology

[0002] In the field of aluminum plate processing, aluminum plate bending machines are the core equipment for bending and forming aluminum plates, and are widely used in industries such as aerospace, rail transportation, building decoration, and home appliance manufacturing. Their main function is to use mechanical force to drive the bending mechanism, bending flat aluminum plates into workpieces of specific shapes according to preset angles and curvatures, meeting the size and form requirements of aluminum plate structural components in different scenarios.

[0003] Aluminum plate bending machines typically consist of a frame, clamping mechanism, bending drive system, die changing components, and control system. Depending on processing requirements, they can be categorized into manual, semi-automatic, and fully automatic bending machines. Fully automatic models, with their high precision and stability, have become the mainstream equipment for large-scale aluminum plate processing. In actual production, the processing efficiency and workpiece accuracy of a bending machine depend not only on the stability of the bending drive system but also on the effectiveness of fixing the aluminum plate before bending. If the aluminum plate is not securely fixed, it is prone to displacement during bending, leading to dimensional deviations or even scrapping of the workpiece. Conversely, cumbersome fixing procedures directly extend the processing cycle, impacting overall production efficiency.

[0004] However, existing aluminum plate bending devices have significant shortcomings in the aluminum plate fixing process: most traditional bending machines use manually adjustable mechanical pressure blocks or single pneumatic grippers for clamping. When fixing aluminum plates, operators need to manually adjust the position of the pressure blocks, tighten the bolts one by one, or repeatedly calibrate the fit between the grippers and the aluminum plates. Especially for aluminum plates of different sizes, it is necessary to frequently change the appropriate clamping components or adjust the fixing parameters. The operation steps are cumbersome and cannot achieve rapid fixing.

[0005] The aforementioned defects in the fixing process directly lead to a significant reduction in processing efficiency, and the increased labor costs associated with repeated manual adjustments further increase the overall cost of aluminum plate processing, making it difficult to meet the demands of modern manufacturing for efficient and low-cost production. Therefore, developing a bending machine for aluminum plate processing with a rapid fixing function has become a key direction for solving the pain points of existing technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a bending machine for aluminum plate processing to solve the problems mentioned in the background art.

[0007] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0008] A bending machine for aluminum plates includes a fixed frame with support platforms installed on both sides. An electric telescopic rod is installed on the top surface of the fixed frame, and a connecting rod slides vertically inside the fixed frame. The telescopic end of the electric telescopic rod is connected to the connecting rod, and a bending block is installed on the free end of the connecting rod. A pair of first connecting strips are installed on the side of the connecting rod. Each pair of support platforms has a limiting groove on its top surface, and a fixing block is located directly above each limiting groove. A second connecting strip is installed on the top surface of each fixing block. Several springs connect the first and second connecting strips. The fixing block contacts the limiting groove. By linking the fixing block and the bending block with the electric telescopic rod, an automated process of fixing and bending the aluminum plate is achieved, eliminating the need for manual adjustment of the fixing structure and solving the problem of cumbersome fixing in traditional equipment. The elastic force of the springs can adapt to the fixing requirements of aluminum plates of different thicknesses, improving equipment adaptability, shortening the single processing cycle, and increasing production efficiency.

[0009] Furthermore, in its natural state, the bottom surface of the fixing block is located below the bottom surface of the bending block, ensuring the sequence of fixing and bending actions, preventing the aluminum plate from shifting due to the bending block contacting the aluminum plate first, and improving bending accuracy; the timing of actions can be coordinated without additional control programs, simplifying the equipment control logic.

[0010] Furthermore, a first bolt connects the second connecting strip and the fixing block, and a second bolt connects the first connecting strip and the connecting rod. The bolt connection enables the components to be disassembled, which facilitates the repair and replacement of the spring after it is damaged, reduces the equipment maintenance cost, and further improves the equipment adaptability.

[0011] Furthermore, four sets of limiting rods are installed inside the limiting groove, and four sets of limiting holes are opened on the bottom surface of the fixing block. The limiting rods slide in the limiting holes. The cooperation between the limiting rods and the limiting holes improves the stability of the movement of the fixing block, ensuring that the fixing block always presses the aluminum plate vertically, avoiding the aluminum plate from being not firmly fixed or bending deviation due to the offset of the fixing block, and ensuring processing accuracy.

[0012] Furthermore, flanges are installed on the outer sides of the telescopic ends of both the connecting rod and the electric telescopic rod, and several third bolts are connected between the flanges.

[0013] Furthermore, the bottom surface of the fixing block is embedded with several balls. Since the two ends of the aluminum plate need to move closer to the center when bending, the balls can reduce the friction between the two ends of the aluminum plate and the limiting groove when bending.

[0014] Furthermore, the bottom surface of the bending block is arc-shaped. The arc design improves the smoothness of aluminum plate bending and the quality of finished products, and reduces bending defects.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the bending machine for aluminum plate processing, through the linkage of the electric telescopic rod with the fixing block and the bending block, combined with the design of spring elastic fixing, limit guidance, and detachable connection, realizes the rapid fixing and bending of aluminum plates. It can not only adapt to the processing needs of aluminum plates of different sizes and thicknesses, but also ensure processing accuracy and efficiency, while reducing operation and maintenance costs, and meeting the needs of modern manufacturing industry for efficient and low-cost aluminum plate processing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 5This utility model provides a technical solution: a bending machine for aluminum plate processing, including a fixed frame 1, with support platforms 2 installed on both sides of the fixed frame 1, an electric telescopic rod 5 installed on the top surface of the fixed frame 1, and a connecting rod 12 vertically sliding inside the fixed frame 1. The telescopic end of the electric telescopic rod 5 is connected to the connecting rod 12, and a bending block 16 is installed on the free end of the connecting rod 12. A pair of first connecting strips 6 are installed on the side of the connecting rod 12. The top surfaces of the pair of support platforms 2 each have limiting grooves 3, and a fixing block 10 is located directly above the pair of limiting grooves 3. A second connecting strip 7 is installed on the top surface of the fixing block 10. The first connecting strip 6 and the second connecting strip 7 are connected to each other. Several springs 9 are connected between the strips 7. The fixing block 10 and the limiting groove 3 are in contact. During processing, the aluminum plate is placed above the limiting groove 3 of the support platform 2. The electric telescopic rod 5 is started, and its telescopic end pushes the connecting rod 12 to slide vertically downward along the fixing frame 1. The connecting rod 12 drives the first connecting strip 6 to move down synchronously. The springs 9 push the second connecting strip 7 and the fixing block 10 to move down, so that the fixing block 10 first contacts the aluminum plate and presses it firmly. The connecting rod 12 continues to move down, which drives the bending block 16 to contact the aluminum plate and complete the bending operation. After the bending is completed, the electric telescopic rod 5 is reset, and the springs 9 rebound and drive the fixing block 10 to detach from the aluminum plate, realizing rapid material removal.

[0024] As an embodiment of this utility model, the bottom surface of the fixing block 10 in its natural state is located below the bottom surface of the bending block 16. The fixing block 10 is lower in its natural state. When the electric telescopic rod 5 drives the connecting rod 12 to move down, the fixing block 10 can contact the aluminum plate first and complete the fixing of the aluminum plate in advance. After the fixing block 10 presses the aluminum plate, the bending block 16 continues to move down to bend, so as to avoid displacement of the aluminum plate before bending.

[0025] As an embodiment of this utility model, a first bolt 8 is connected between the second connecting strip 7 and the fixing block 10, and a second bolt 15 is connected between the first connecting strip 6 and the connecting rod 12. The second connecting strip 7 and the fixing block 10 are detachably connected by the first bolt 8, and the first connecting strip 6 and the connecting rod 12 are detachably connected by the second bolt 15. When the spring 9 needs to be replaced, the bolts can be unscrewed for quick disassembly and assembly.

[0026] As an embodiment of this utility model, four sets of limiting rods 4 are installed inside the limiting groove 3, and four sets of limiting holes are opened on the bottom surface of the fixing block 10. The limiting rods 4 slide in the limiting holes. When the fixing block 10 moves up and down, the limiting rods 4 slide along the limiting holes of the fixing block 10, limiting the movement direction of the fixing block 10 and preventing it from horizontally shifting or tilting during the pressing of the aluminum plate.

[0027] As an embodiment of this utility model, flanges 13 are further installed on the outer sides of the telescopic ends of the connecting rod 12 and the electric telescopic rod 5. Several third bolts 14 are connected between the flanges 13. The flanges 13 increase the contact area between the connecting rod 12 and the telescopic end of the electric telescopic rod 5. The third bolts 14 firmly connect the two to ensure that the driving force of the electric telescopic rod 5 is stably transmitted to the connecting rod 12.

[0028] As an embodiment of this utility model, a plurality of balls 11 are embedded in the bottom surface of the fixing block 10, and the aluminum plate can slide along the balls 11 on the bottom surface of the fixing block 10 to reduce the frictional resistance between the aluminum plate and the limiting groove 3.

[0029] Specifically, the ball bearing 11 is made of high carbon chromium bearing steel (such as GCr15). This material has high hardness (hardness can reach HRC60-65 after quenching), high wear resistance and excellent compressive strength, and can withstand the pressure when the fixing block 10 presses the aluminum plate without deformation or damage.

[0030] As an embodiment of this utility model, the bottom surface of the bending block 16 is arc-shaped. When the bending block 16 with the arc-shaped bottom surface comes into contact with the aluminum plate, it can uniformly transmit bending force through the arc-shaped surface, so that the aluminum plate bends along the arc-shaped trajectory to form a smooth bending arc, thus avoiding cracking or deformation of the aluminum plate at the bending point due to force concentration.

[0031] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
