[0002] Aluminum alloy profiles are widely used in construction, furniture, transportation, and other fields due to their advantages such as light weight, high strength, and ease of processing. Bending is a frequent process in their manufacturing. Currently, most commonly used bending equipment relies on fixed molds or manual operation, making it difficult to flexibly adapt to different bending angles, positions, and profile specifications. With the increasing number of customized products, the requirements for processing efficiency and precision in multi-angle, multi-position bending of profiles are constantly rising.

[0003] However, existing bending equipment generally suffers from inconvenient adjustment. When changing the bending position or shape, it is often necessary to stop the machine to replace the mold or manually adjust the positioning repeatedly, which is cumbersome and time-consuming, affecting processing efficiency. Moreover, it is difficult to achieve continuous adjustment of the bending point accurately and quickly on the same machine, resulting in poor adaptability to different bending requirements, increasing production costs and operational complexity. Therefore, an adjustable bending device for aluminum alloy profile processing is proposed here. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This utility model provides an adjustable bending device for processing aluminum alloy profiles, including a worktable 1, which serves as the basic support platform for the entire device. A vertical plate 2 is fixedly connected to the upper side of the worktable 1, serving as the main vertical support structure. A positioning frame 3 is fixedly connected to the upper side of the worktable 1. The positioning frame 3 is used to accommodate and initially position the aluminum alloy profile to be processed. A positioning mechanism is installed on the upper side of the positioning frame 3, comprising a fixed plate 4, an electric push rod 5, and a pressure plate 6. The fixed plate 4 is fixedly connected to the outside of the vertical plate 2, providing a mounting base for the electric push rod 5, and is installed directly above the positioning frame 3 to ensure that the pressure plate 6 can be aligned with the profile. The electric push rod 5 is fixedly connected to the outside of the fixed plate 4, serving as a power source to drive the pressure plate 6 to move up and down. The pressure plate 6 is fixedly connected to the end of the output shaft of the electric push rod 5, used to press the profile downwards for positioning. The electric push rod 5 is slidably connected to the inside of the positioning frame 3 to ensure movement stability.

[0025] like Figure 2 As shown, the positioning frame 3 is slidably connected to the two sides of the adjustment frame 7. The adjustment frame 7 is used to adjust the bending position of the profile. The outside of the upright plate 2 is provided with two sets of symmetrically arranged sliding grooves 8. The sliding grooves 8 provide a guiding function for the slider 9, and the slider 9 is slidably connected to the inside of the sliding grooves 8. The slider 9 is a connecting component and is fixedly connected to the adjustment frame 7, which drives the adjustment frame 7 to move synchronously.

[0026] like Figure 3 as well as Figure 4 As shown, a translation adjustment mechanism is installed at the rear end of the upright plate 2. The translation adjustment mechanism includes a fixed block 10, a connecting plate 11, a first motor 12, and a lead screw 13. The fixed block 10 is fixedly connected to the other side of the slider 9 as a transmission connector, and the fixed block 10 is slidably connected to the rear side of the upright plate 2 to ensure the smoothness of the translation movement. The connecting plate 11 is fixedly connected to the rear side of the upright plate 2 to support the lead screw 13. There are two sets of connecting plates 11 arranged symmetrically to ensure balanced force. The first motor 12 is fixedly connected to the outside of one set of connecting plates 11 as a translation drive power source. The lead screw 13 is rotatably connected between the two sets of connecting plates 11 to convert the rotational motion into linear motion. The lead screw 13 and the first motor 12 are fixedly connected to realize power transmission. The fixed block 10 and the lead screw 13 are threadedly connected to realize precise position adjustment.

[0027] like Figure 5As shown, the outer side of the upright plate 2 has two sets of symmetrically arranged lifting grooves 14. The lifting grooves 14 provide a vertical movement track for the locking block 15. The locking block 15 is slidably connected to the inner side of the lifting groove 14. The locking block 15 acts as a connecting member to drive the abutment plate 16 to move. The abutment plate 16 is fixedly connected to the outer side of the locking block 15. The abutment plate 16 acts directly on the profile as a bending actuator. The abutment plate 16 is installed on both sides of the two sets of sliding grooves 8 to ensure accurate bending position. A tension spring 17 is fixedly connected inside the lifting groove 14 to provide a restoring force, and the end of the tension spring 17 is fixedly connected to the upper side of the locking block 15 to maintain the initial position of the locking block 15.

[0028] like Figure 6 As shown, a bending mechanism is installed between the clamping block 15 and the worktable 1. The bending mechanism includes a mounting plate 18, a second motor 19, a rotating rod 20, and a pull rope 21. The mounting plate 18 is fixedly connected to the upper side of the worktable 1, providing a mounting base for the second motor 19. The second motor 19 is fixedly connected to the outside of the mounting plate 18, serving as a bending drive power source. The rotating rod 20 is rotatably connected between the mounting plate 18 and the lifting groove 14, used to wind the pull rope 21. The pull rope 21 is fixedly connected to the outside of the rotating rod 20, transmitting tension to drive the clamping block 15 to move downward. The end of the pull rope 21 is fixedly connected to the bottom of the clamping block 15, realizing the bending action.

[0029] The working principle of this utility model is as follows: When bending aluminum alloy profiles, the profile is first passed horizontally through the adjustment frame 7 and the positioning frame 3 to ensure that the middle section is accurately placed inside the positioning frame 3. Then, the electric push rod 5 of the positioning mechanism is started, and its output shaft pushes the pressure plate 6 to move downward. The pressure plate 6 passes through the positioning frame 3 and presses tightly against the upper surface of the profile to achieve stable positioning. Then, the second motor 19 of the bending mechanism is started to drive the rotating rod 20 to rotate. The pull rope 21 is wound and tightened with the rotating rod 20, and the downward pull of the locking block 15 causes it to slide down along the lifting groove 14 on the vertical plate 2. The locking block 15 drives the abutment plate 16 fixed thereto to move down synchronously, applying vertical pressure to the overhanging section of the profile to complete the bending and forming.

[0030] When it is necessary to adjust the bending shape or position, the first motor 12 of the translation adjustment mechanism is started. The first motor 12 drives the lead screw 13 to rotate. Since the fixed block 10 and the lead screw 13 are connected by a thread, and the fixed block 10 is restricted by the sliding constraint of the rear side of the vertical plate 2, the rotation of the lead screw 13 forces the fixed block 10 to move laterally. The fixed block 10 drives the slider 9 fixed to it to slide in the slide groove 8, thereby driving the adjustment frame 7 fixed to the slider 9 to move synchronously along both sides of the positioning frame 3. Through the precise translation of the position of the adjustment frame 7, the actual bending position of the profile under the action of the abutment plate 16 can be freely set, so as to flexibly adapt to the bending processing requirements of different lengths, angles or shapes, and significantly improve the adaptability and ease of operation of the device to different profile bending processes.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
