Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, specifically to an arc-shaped bonding and fixing device for bending aluminum profiles. Background Technology

[0002] Aluminum profiles are materials with specific cross-sectional shapes made primarily of aluminum through hot extrusion or other processing methods. They offer advantages such as ease of processing and recyclability. Thanks to the excellent plasticity and ductility of aluminum profiles, aluminum profile bending and fitting fixing devices are mainly used for processing profiles with complex cross-sections, such as rectangular tubes, channel steel, and angle aluminum. They need to match the non-circular cross-sections of the profiles, such as grooves, bosses, and porous structures. They are suitable for making various arc, circular, or irregular structural components through bending processes. They are widely used in the production of curved windows for building curtain walls, curved car luggage racks, and curved supports for industrial frames.

[0003] Traditional curved fitting and fixing devices for aluminum profile bending have relatively simple shapes and structures, making it difficult to adjust to the specific shape of the aluminum material and achieve good fit with aluminum materials of various shapes. This results in several shortcomings in practical use. For example, the fixing effect is poor for irregularly shaped or non-standard aluminum materials. Traditional devices, due to their use of molds with fixed curvature and simple clamping structures, are unable to adapt to the complex contours of non-standard aluminum materials. This leads to some areas of the aluminum profile not fitting tightly to the mold during the fixing process, resulting in large gaps. During bending, these unfitted areas experience uneven stress, making them prone to wrinkles, twisting, and other deformation problems. Utility Model Content

[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] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: an arc-shaped bonding and fixing device for bending aluminum profiles, including a base 1, a bracket 11 fixedly installed on the upper end of the base 1, two pressure blocks 2 at both ends of the middle of one side of the bracket 11, bonding plates 22 rotatably installed above and below the middle of one side of the two pressure blocks 2, guide grooves 23 on one side of each of the two bonding plates 22, fixing blocks 24 fixedly installed in the middle of one side of the two pressure blocks 2, limiting rods 25 fixedly installed in the middle of the two fixing blocks 24, limiting plates 26 fixedly installed at both ends of the middle of the limiting rods 25, multiple connecting rods 27 fixedly installed around the middle of the middle of the two fixing blocks 24, limiting rods 28 fixedly installed at one end of each of the multiple connecting rods 27, and limiting rods 28 fixedly installed above and below the middle of the multiple limiting rods 28. Limiting plate 29 is installed. Multiple bonding plates 30 are evenly rotated and installed on one side of multiple bonding plates 22. A notch 32 is opened in the middle of one side of each bonding plate 30. The two ends of limiting rod 25 are slidably engaged with the middle of the guide groove 23 opened in the two bonding plates 22. One end of connecting rod 27 is located in the middle of the notch 32. Limiting plate 26 abuts against one side of the guide groove 23 opened in the two bonding plates 22. A guide groove 31 is opened on one side of the middle of each bonding plate 30. The guide groove 31 and the notch 32 are connected. The two ends of limiting rod 28 are slidably engaged with the middle of the guide groove 31. The two limiting plates 29 of each limiting rod 28 abut against the upper and lower parts of the connection between the corresponding notch 32 and the guide groove 31.

[0024] In this embodiment, a bracket 11 is fixedly installed on the upper end of the base 1. The base 1 and the bracket 11 can provide support for the installation of subsequent components. At both ends of the middle of one side of the bracket 11, pressing blocks 2 are symmetrically arranged. A first-fitting plate 22 is installed on the upper and lower sides of the middle of one side of the pressing block 2 via a rotatable connection. The first-fitting plate 22 can rotate flexibly to adapt to aluminum materials of different shapes. A fixing block 24 is fixedly installed on the middle of one side of each of the two pressing blocks 2. The fixing block 24 is used to fix a first-limiting rod 25. A first-limiting plate 26 is fixedly installed on both ends of the middle of the first-limiting rod 25. The first-limiting plate 26 can limit the fitting plate 22 to prevent movement. Simultaneously, multiple connecting rods 27 are evenly fixedly installed around the middle of the two fixing blocks 24, connecting the fixing blocks 24 to a second-limiting rod 28. A second-limiting rod 28 is fixedly installed on one end of each of the multiple connecting rods 27. A second-limiting plate 29 is fixedly installed on the upper and lower sides of the middle of each of the multiple second-limiting rods 28. Multiple bonding plates 30 are evenly and rotatably mounted on one side of the 22. The bonding plates 30 further increase the bonding area with the aluminum profile. At the same time, notches 32 are opened in the middle of the multiple bonding plates 30 to provide installation positions for the ends of multiple connecting rods 27. The two ends of the limiting rod 25 are respectively slidably engaged with the middle of the guide grooves 23 opened in the two bonding plates 22, so that the limiting rod 25 can slide in the guide grooves 23. A notch 32 is opened on one side of the middle of the bonding plate 22. The second guide groove 31 is connected to the notch 32, forming a continuous movable space to provide rotation space for the second bonding plate 30. The two ends of the second limiting rod 28 are respectively slidably engaged with the middle of the second guide groove 31, so that the second limiting rod 28 can slide in the second guide groove 31. The two limiting plates 29 of each second limiting rod 28 abut against the upper and lower parts of the connection between the corresponding notch 32 and the second guide groove 31, which can limit the bonding plate 30.

[0025] Before the aluminum profile is bent, the two pressing blocks 2 are in a non-working position, i.e., not pressed down. Both the first bonding plate 22 and the second bonding plate 30 are in an unfolded state, reserving space for the aluminum profile. When the aluminum profile needs to be fixed, the two pressing blocks 2 move downwards, causing the two bonding plates 22 to simultaneously approach the aluminum profile. Since the first bonding plate 22 is rotatably connected to the pressing blocks 2, it can rotate flexibly according to the surface curvature of the aluminum profile, adaptively fitting the curved surface and avoiding deformation caused by hard compression. During the process, the two ends of the limiting rod 25 slide within the guide groove 23 of the first bonding plate 22, limiting the movement range of the first bonding plate 22 and performing initial limiting and fitting of the aluminum profile. As the pressing blocks 2 continue to press down, the connecting rod 27 moves downwards with the fixing block 24, and the limiting rod 28 at its end causes the second bonding plate 30 to rotate around the first bonding plate 22 along the surface of the aluminum profile. Since the second bonding plate 30 is evenly distributed on one side of the first bonding plate 22, it can wrap around the aluminum profile after rotation, further increasing the bonding area and improving the fixing accuracy. The two ends of the second limiting rod 28 slide within the guide groove 31 of the second bonding plate 30 until the second bonding plate 30 rotates to completely bond with the aluminum profile. The second limiting plate 29 abuts against the connection between the notch 32 and the guide groove 31, which can limit the movement range of the second bonding plate 30 and prevent it from loosening during processing. Through the above-mentioned linkage, the first bonding plate 22 and the second bonding plate 30 form a full-coverage fixation of the arc surface of the aluminum profile, limiting its displacement and deformation in the bending direction. At this time, the aluminum profile is stably clamped between the bonding device and the bending mold.

[0026] Example 2: As Figure 1-5 As shown, a mounting groove 15 is provided in the middle of the base 1. An arc-shaped mold 12 is connected to the middle of the mounting groove 15 by screw threads. A placement groove 13 is provided in the middle of the arc-shaped mold 12. A bottom support frame 14 is fixedly installed in the middle of the lower end of the base 1. The upper end of the bottom support frame 14 abuts against the bottom of the arc-shaped mold 12. A hydraulic cylinder 16 is fixedly installed in the middle of the upper end of the bracket 11. The output end of the hydraulic cylinder 16 passes through the upper end of the bracket 11 and a pressing plate 17 is fixedly installed by screws. The pressing plate 17 and the placement groove 13 are engaged. Slide grooves 18 are provided on both sides of the middle of the bracket 11. A wire rod 20 is rotatably installed in the middle of one slide groove 18. A guide rod 19 is fixedly installed in the middle of the other slide groove 18. The wire rod 20 is threadedly connected to the slider 21 of one of the lower pressing blocks 2. The guide rod 19 is slidably engaged with the slider 21 of the other lower pressing block 2. The two lower pressing blocks 2 are located on both sides of the pressing plate 17.

[0027] In this embodiment, the base 1 serves as the basic supporting component of the entire device. A mounting groove 15 is provided in the middle, providing installation space for the arc-shaped mold 12. The arc-shaped mold 12 is threadedly connected to the mounting groove 15 with screws, securing it firmly to the base 1. A placement groove 13 is provided in the middle of the arc-shaped mold 12 for placing the aluminum profile to be processed. A bottom support frame 14 is fixedly installed at the lower middle of the base 1, providing support for the arc-shaped mold 12 and enhancing stability. A bracket 11 is fixed to the base 1, and a hydraulic cylinder 16 is fixedly installed at the upper middle of its upper end. The output end of the hydraulic cylinder 16 extends downward through the upper end of the bracket 11 and is fixedly installed with an extrusion plate 17 by screws. The shape and size of the extrusion plate 17 are adapted to the placement groove 13 of the arc-shaped mold 12, enabling a mating and snap-fit ​​connection. When the hydraulic cylinder 16 is working, the extrusion plate 17 can move up and down within the placement groove 13 to extrude the aluminum profile placed therein. The bracket 11 has symmetrically arranged sliding grooves 18 on both sides of its middle section. A wire rod 20 is rotatably installed in the middle of one sliding groove 18, while a guide rod 19 is fixedly installed in the middle of the other sliding groove 18. The sliders 21 of the two lower pressure blocks 2 respectively cooperate with the wire rod 20 and the guide rod 19. The slider 21 of one lower pressure block 2 is threadedly connected to the wire rod 20, while the slider 21 of the other lower pressure block 2 is slidably snap-fitted with the guide rod 19. This arrangement allows the two lower pressure blocks 2 to move up and down along the sliding groove 18 under the drive of the wire rod 20. The two lower pressure blocks 2 are located on both sides of the extrusion plate 17, playing a role in auxiliary fixing and positioning during the aluminum profile processing.

[0028] The aluminum profile to be processed is placed in the placement groove 13 in the middle of the arc mold 12. Then, the electric screw 20 is started. When the electric screw 20 rotates, it will drive the two lower pressure blocks 2 to move downward along the sliding grooves 18 on both sides of the middle of the bracket 11 until the two lower pressure blocks 2 initially fix the aluminum profile in the placement groove 13, thereby restricting the horizontal movement of the aluminum profile and preparing for subsequent extrusion processing. Then, the hydraulic cylinder 16 is activated to push the extrusion plate 17 downward. Since the shape and size of the extrusion plate 17 are compatible with the placement groove 13 of the arc mold 12, they can be engaged and can extrude the aluminum profile in the placement groove 13. During the extrusion process, the lower pressure block 2 continuously applies a fixing force to the aluminum profile, which works in conjunction with the pressure of the extrusion plate 17 to cause the aluminum profile to undergo plastic deformation according to a predetermined arc under the constraint of the arc die 12, completing the bending process. After the aluminum profile bending process is completed, the hydraulic cylinder 16 drives the extrusion plate 17 to return to its original position and leave the placement groove 13. Subsequently, the lead screw 20 rotates in the opposite direction, driving the two lower pressure blocks 2 to move upward along the slide groove 18, releasing the fixing of the aluminum profile. At this time, the processed aluminum profile can be taken out from the placement groove 13, the device returns to its initial state, and it is ready for the next processing operation. The arc die 12, the mounting groove 15 in the middle of the base 1, and the extrusion plate 17 installed at the output end of the hydraulic cylinder 16 are all connected by screws, which can be quickly replaced to adapt to the processing requirements of aluminum profiles with different arcs.
