Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile correction technology, specifically an aluminum profile bending correction device. Background Technology

[0002] In the field of aluminum profile door and window manufacturing, aluminum profiles are the core processing material, and their production process is crucial. Specifically, the production of aluminum profiles requires heating the raw materials to a softened state first, and then extruding them through an extruder. However, during the forming process, due to the influence of material characteristics and process factors, aluminum profiles often bend and deform. In order to ensure that the product quality meets the standards, it is necessary to use a bending correction device to accurately correct them.

[0003] Currently, the roller-type aluminum profile bending correction device widely used in the industry has shown significant technical advantages due to its unique structural design - multiple rollers arranged in an orderly manner. When the aluminum profile passes through the roller group, it will continuously bear bending and reverse bending forces, thereby gradually eliminating the original bending deformation. This continuous correction mode is not only highly efficient, but also particularly suitable for large-scale mass production scenarios.

[0004] However, existing roller straightening devices exhibit significant shortcomings when dealing with complex and diverse aluminum profile shapes. For some aluminum profiles with special cross-sectional shapes, such as T-shaped or concave, the rollers of the roller straightening device cannot closely fit the vertical part of the aluminum profile during the straightening process, resulting in ineffective straightening of that part and a significant reduction in the overall straightening effect. Therefore, an aluminum profile curvature straightening device is proposed to address the above problems. Utility Model Content

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figures 1-6This utility model provides an aluminum profile bending correction device, including a support platform 1; a straightening roller 2 is provided on the side wall of the top of the support platform 1, a cylindrical cylinder 3 is slidably connected to the outer wall of the straightening roller 2, a circular ring 31 is slidably connected to the outer wall of the cylindrical cylinder 3, a through groove 311 is opened on the outer wall of the cylindrical cylinder 3, a slider 38 is slidably connected to the middle of the through groove 311, one end of the slider 38 is fixed to the middle of the circular ring 31, a connecting plate 310 is rotatably connected to the middle of the other end of the slider 38, and a hinge block 39 is rotatably connected to the end of the connecting plate 310. A rectangular block 312 is fixed to the side wall of block 39. A through groove 22 is opened at the end of the straightening roller 2. A sliding frame 34 is slidably connected to the middle of the through groove 22. The outer wall of the rectangular block 312 is slidably connected to the middle of the sliding frame 34. A limiting component is provided at the end of the sliding frame 34. During operation, when straightening the curvature of the aluminum profile, the aluminum profile to be straightened can be placed between multiple sets of straightening rollers 2. The driving element provided on the support platform 1 causes the upper and lower rows of straightening rollers 2 to merge and clamp and straighten the aluminum profile. Some aluminum profiles may have special shapes. Specifically, there are vertical connecting blocks that can clamp and correct the vertical part using multiple sets of rings 31, ensuring the quality of aluminum profile correction. When it is necessary to adjust the spacing of the multiple sets of rings 31 according to aluminum profiles of different thicknesses, the limiting component can be released from the limiting position of the sliding frame 34. Subsequently, the sliding frame 34 can be pushed to slide in the middle of the through slot 22. The sliding frame 34 will drive the hinge block 39 to move through the rectangular block 312. The hinge block 39 will rotate with the connecting plate 310, causing the overall angle of the connecting plate 310 to change. The other end will rotate with the slider 38, causing the slider 38 to slide in the middle of the through slot 311. The slider 38 will drive the ring 31 to move. In this way, multiple sets of rings 31 can be adjusted according to aluminum profiles of different thicknesses, improving applicability. The upper side wall of the support platform 1 is evenly provided with multiple sets of straightening rollers 2, which are distributed in two rows. There is also a drive structure to control and adjust the distance between the two rows of straightening rollers 2. These are all existing technologies and can be implemented by those skilled in the art. Since they are existing technologies, they will not be described in detail in this case.

[0028] Furthermore, such as Figures 2-3 and Figure 6As shown, the limiting component includes a limiting block 35, which is slidably connected to the inner wall of the end of the sliding frame 34. A connecting plate 352 is fixedly connected to the bottom of the limiting block 35. A limiting groove 23 is formed in the middle of the through groove 22, and the limiting block 35 is inserted into the middle of the limiting groove 23. A pressing block 351 is fixedly connected to the top of the other end of the connecting plate 352. The pressing block 351 is slidably connected to the inner wall of the end of the sliding frame 34 located on one side of the limiting block 35. During operation, the limiting component ensures the stability of the sliding frame 34. The specific operation of the limiting component is as follows: When it is necessary to release the limit on the sliding frame 34, press the pressing block 351. The limiting block 35 will move through the connecting plate 352. In addition, moving the connecting plate 352 will compress the spring 353 until the limiting block 35 is completely disengaged from the middle of the limiting groove 23. At this time, the sliding frame 34 can be pushed to adjust its position. After adjustment, release the pressing block 351. The spring 353 will push the limiting block 35 back to its original position through the connecting plate 352 due to its elasticity, so that it inserts into the middle of another set of limiting grooves 23, thus limiting the sliding frame 34 and improving its practicality.

[0029] Furthermore, such as Figures 1-2 As shown, the outer wall of the straightening roller 2 has a through groove 21. A sliding shell 32 is fixedly connected to the middle of the cylindrical tube 3. The outer wall of the end of the sliding shell 32 is slidably connected to the middle of the through groove 21. The hinge block 39 is specifically slidably connected to the middle of the sliding shell 32. A through groove 33 is opened on the side wall of the sliding shell 32. The outer wall of the sliding frame 34 slides in the middle of the through groove 33. A bidirectional threaded rod 4 is threadedly connected to one side of the side wall of the sliding frame 34 located in the through groove 33. The outer wall of the end of the bidirectional threaded rod 4 is rotatably connected to the inner wall of the end of the straightening roller 2. During operation, when it is necessary to adjust the distance between multiple sets of cylindrical tubes 3 according to the overall width of different aluminum profiles, the bidirectional threaded rod 4 can be rotated. At this time, the sliding shell 32 threadedly connected to the outer wall of the bidirectional threaded rod 4 will slide in the middle of the through groove 21, while another set of sliding shells 32 will have the same movement, but in the opposite direction. In this way, aluminum profiles of different widths can be clamped and straightened, improving practicality.

[0030] Furthermore, such as Figure 4As shown, a movable block 313 is fixedly connected to the side wall of the rectangular block 312, and a groove 341 is provided in the middle of the sliding frame 34. The movable block 313 is slidably connected to the middle of the groove 341. During operation, when the position of the sliding shell 32 is adjusted by rotating the bidirectional threaded rod 4, the sliding shell 32 will drive the rectangular block 312 to slide in the middle of the sliding frame 34, ensuring that the connection between the structures can always be maintained. The rectangular block 312 will drive the movable block 313 to slide in the middle of the groove 341. Through the cooperation between the movable block 313 and the groove 341, it is ensured that the rectangular block 312 can move smoothly when the sliding frame 34 is pushed.

[0031] Furthermore, such as Figure 3 As shown, the side wall of the ring 31 has a groove 37, and a ball bearing 36 is slidably connected in the middle of the groove 37. During operation, the ball bearing 36 directly contacts the aluminum profile. When the aluminum profile moves, the ball bearing 36 rolls on the surface of the aluminum profile, reducing the risk of wear on the aluminum profile.

[0032] Furthermore, such as Figures 2-3 and Figure 5 As shown, multiple sets of limiting blocks 35, connecting plates 352, and pressing blocks 351 are provided, and these multiple sets of limiting blocks 35, connecting plates 352, and pressing blocks 351 are symmetrically arranged with the center line of the sliding frame 34 as the axis of symmetry. A spring 353 is fixedly connected to the bottom of the connecting plate 352, and the bottom end of the spring 353 is fixedly connected to the top of the multiple sets of connecting plates 352. During operation, the multiple sets of limiting blocks 35, connecting plates 352, and pressing blocks 351 can ensure the stability of the sliding frame 34 in limiting position, and the multiple sets of connecting plates 352 are elastically connected by the spring 353 to ensure the stability of the limiting position.

[0033] Furthermore, such as Figures 1-2 and Figure 5 As shown, multiple sets of cylindrical cylinder 3, ring 31, and sliding shell 32 are provided, and the multiple sets of cylindrical cylinder 3, ring 31, and sliding shell 32 are symmetrically arranged with the center line of the straightening roller 2 as the axis of symmetry. The multiple sets of sliding shell 32 are threadedly connected to the outer wall of the other end of the bidirectional threaded rod 4. During operation, the multiple sets of cylindrical cylinder 3, ring 31, and sliding shell 32 can be driven by the bidirectional threaded rod 4 to clamp and straighten aluminum profiles of different widths, thus improving practicality.

[0034] Working principle: When correcting the curvature of aluminum profiles, the profile to be corrected can be placed between multiple sets of correcting rollers 2. Driven by the drive element on the support platform 1, the upper and lower rows of correcting rollers 2 are merged to clamp and correct the aluminum profile. Some aluminum profiles may have special shapes with vertical connecting blocks. Multiple sets of rings 31 can clamp and correct the vertical parts, ensuring the quality of the aluminum profile correction. When it is necessary to adjust the spacing of the multiple sets of rings 31 according to different thicknesses of aluminum profiles, pressing the pressing block 351 will cause the limiting block 35 to move via the connecting plate 352. Additionally, moving the connecting plate 352 will compress the spring 353 until the limiting block 35 is completely disengaged from the center of the limiting groove 23. Then, it can be pushed... The sliding frame 34 slides in the middle of the second through slot 22. The sliding frame 34 will drive the hinge block 39 to move through the rectangular block 312. The hinge block 39 will rotate with the connecting plate 310, causing the overall angle of the connecting plate 310 to change. The other end of the connecting plate 310 will rotate with the slider 38, causing the slider 38 to slide in the middle of the fourth through slot 311. The slider 38 will drive the ring 31 to move. After adjustment, the pressing block 351 can be released. At this time, the spring 353 will push the limiting block 35 to reset through the connecting plate 352 through its own elasticity, so that it inserts into the middle of another set of limiting slots 23 to limit the sliding frame 34. In this way, multiple sets of rings 31 can be adjusted according to aluminum profiles of different thicknesses, improving applicability.

[0035] When it is necessary to adjust the distance between multiple sets of cylindrical tubes 3 according to the overall width of different aluminum profiles, the bidirectional threaded rod 4 can be rotated. At this time, the sliding shell 32 threaded to the outer wall of the bidirectional threaded rod 4 will slide in the middle of the through groove 21, while another set of sliding shells 32 will have the same movement, but the direction of movement is opposite. In this way, aluminum profiles of different widths can be clamped and corrected, improving practicality.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
