Description

Technical Field

[0001] This utility model relates to the technical field of aluminum profile straightening equipment, and in particular to an aluminum profile straightening device. Background Technology

[0002] Aluminum profiles are profiled products with specific cross-sectional shapes and dimensions, made primarily of aluminum through extrusion, rolling, and forging processes. Square aluminum tubes are square-section tubular profiles produced through extrusion. These square tubes are prone to bending and deformation during extrusion, transportation, or storage. When assembling building curtain wall frames, if the square tubes are not straight, gaps and deviations will occur during frame splicing, affecting not only the flatness and sealing of the curtain wall but also potentially reducing the overall structural stability. Using a straightening machine can eliminate the bending deformation of the square tubes, ensuring they meet straightness requirements and guaranteeing precise installation and project quality.

[0003] In existing aluminum profile straightening equipment, some straightening machines rely on handwheels to adjust the spacing between the upper and lower roller groups one by one. In this manual adjustment process, the operator's experience and feel become crucial factors, lacking a unified quantitative standard. Because multiple straightening roller groups need to be adjusted individually via handwheels, and there are slight differences in force control and the number of rotations during the adjustment process, deviations in the spacing between the rollers can easily occur. This inconsistency leads to uneven pressure on different parts of the aluminum profile during the straightening process: areas with excessive force are prone to over-deformation, while areas with insufficient force are difficult to straighten completely, ultimately resulting in uneven local stress on the profile, affecting the overall straightening accuracy and yield rate. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing aluminum profile straightening equipment relies on the operator's experience and feel for manually adjusting the roller spacing, lacking a unified quantitative standard. Because slight differences exist during the adjustment of multiple roller sets, uneven pressure distribution can easily occur, affecting straightening accuracy and yield. Therefore, this invention proposes an aluminum profile straightening device.

[0005] The technical solution of this utility model is as follows: An aluminum profile straightening device includes a straightening machine and an aluminum profile body. The straightening machine is provided with a pair of straightening supports, and each straightening support is provided with a manually adjustable movable straightening roller. The device also includes: a lifting plate, disposed on top of the pair of straightening supports, with L-shaped limiting plates at both ends of the lifting plate to prevent the movable straightening roller from moving downwards; a U-shaped bracket disposed on the lifting plate, with both ends of the U-shaped bracket fixedly connected to the top of the corresponding straightening support, and a lifting mechanism on the U-shaped bracket for driving the lifting plate to move up and down; and a positioning mechanism installed on the lifting mechanism, which is used to prevent the lifting plate from moving upwards.

[0006] Optionally, the lifting mechanism includes a motor fixedly connected to the middle of the U-shaped bracket. The output shaft of the motor passes through the U-shaped bracket and is fixedly connected to a first threaded rod. The first threaded rod spirally passes through the middle of the lifting plate. Both ends of the lifting plate are provided with U-shaped brackets that hold the U-shaped bracket. The other end of the U-shaped bracket is fixedly connected to the end of the corresponding L-shaped limiting plate.

[0007] Optionally, both ends of the movable straightening roller are rotatably connected to a second threaded rod. The end of the second threaded rod away from the movable straightening roller spirally passes through the straightening bracket and is fixedly connected to a turntable handle. The end of the L-shaped limiting plate away from the lifting plate is used to lock the turntable handle and move it downwards to the straightening bracket.

[0008] Optionally, the positioning mechanism includes a flat groove formed on the first threaded rod, the flat groove having a length mark, and a positioning nut for locking the lifting plate is screwed onto the first threaded rod.

[0009] Optionally, the end of the first threaded rod away from the motor is fixedly connected to a clamping plate that holds the lifting plate.

[0010] Optionally, each of the straightening brackets is equipped with a fixed straightening roller that corresponds to the upper and lower parts of the movable straightening roller.

[0011] Optionally, the straightening bracket is also provided with a pair of auxiliary straightening rollers corresponding to the movable straightening roller and the fixed straightening roller.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes the combined structure of a straightening machine, a U-shaped bracket, a lifting plate, and a positioning mechanism. When using the device, the motor on the U-shaped bracket is started, driving the first threaded rod to rotate. Combined with the U-shaped retaining plate of the lifting plate, the lifting plate drives the L-shaped limiting plate to synchronously adjust multiple sets of movable straightening rollers, avoiding the differences caused by manual adjustment. At the same time, the adjustment amount is quantified according to the length marking on the plane groove of the first threaded rod, and the spacing is fixed with the positioning nut to ensure that the spacing of each roller is consistent. This ensures that the aluminum profile body is subjected to uniform force, reduces excessive deformation or incomplete straightening, and improves straightening accuracy and pass rate.

[0025] Example

[0026] like Figures 1 to 4 As shown, this utility model proposes an aluminum profile straightening device, including a straightening machine 1 and an aluminum profile body 2. The straightening machine 1 is equipped with a pair of straightening supports 11, which support movable straightening rollers 12, fixed straightening rollers 13, and auxiliary straightening rollers 14, providing a stable installation and working foundation for each straightening roller. The interior of each straightening support 11 is equipped with fixed straightening rollers 13 corresponding to the movable straightening rollers 12. The fixed straightening rollers 13 cooperate with the movable straightening rollers 12 to form a clamping and straightening channel for the aluminum profile body 2, providing stable lower support force for profile straightening. The straightening support 11 is also equipped with a pair of auxiliary straightening rollers 14 corresponding to the movable straightening rollers 12 and fixed straightening rollers 13. The auxiliary straightening rollers 14 correspond to the movable straightening rollers 12 and fixed straightening rollers 13, assisting in clamping and guiding the aluminum profile body 2, enhancing the stability of the profile during the straightening process, and improving the straightening effect. The straightening bracket 11 is equipped with a manually adjustable movable straightening roller 12. The movable straightening roller 12 can be adjusted in position via components such as the lifting plate 4 and the second threaded rod 42. It works in conjunction with the fixed straightening roller 13 to apply straightening force to the aluminum profile body 2, correcting the bending deformation of the profile. A lifting plate 4 is located at the top of each pair of straightening brackets 11. Both ends of the lifting plate 4 are equipped with L-shaped limiting plates 41 that lock the movable straightening roller 12 downwards. The L-shaped limiting plates 41 move with the lifting plate 4, causing the movable straightening roller 12 to move downwards, while simultaneously limiting the position of the turntable handle 43, assisting in the adjustment of the movable straightening roller 12. A U-shaped bracket 3 is located on the lifting plate 4. The U-shaped bracket 3 supports the motor 31 and the first threaded rod 32, providing a mounting carrier for the lifting mechanism and ensuring stable operation of the lifting mechanism. Both ends of the U-shaped bracket 3 are fixedly connected to the top of the corresponding straightening bracket 11.

[0027] Among them, such as Figures 1 to 4As shown, the U-shaped bracket 3 is equipped with a lifting mechanism that drives the lifting plate 4 to move up and down. The lifting mechanism includes a motor 31 fixedly connected to the middle of the U-shaped bracket 3. The motor 31 provides power for the up and down movement of the lifting plate 4, realizing the position adjustment of the movable straightening roller 12. The output shaft of the motor 31 passes through the U-shaped bracket 3 and is fixedly connected to a first threaded rod 32. The length mark 34 at the top of the first threaded rod 32 indicates that the distance between the movable straightening roller 12 and the fixed straightening roller 13 is at its maximum at this time. The positioning nut 35 is adjusted downward on the first threaded rod 32. At this time, the top of the lifting plate 4 abuts against the bottom end of the positioning nut 35, which is the distance that the second threaded rod 42 drives the movable straightening roller 12 to adjust downward. Because each turntable handle 43 drives the second threaded rod 42 to move downward, the bottom end of the turntable handle 43 is blocked by the L-shaped limiting plate 41. The distance that the turntable handle 43 moves downward to abut against the L-shaped limiting plate 41 is the same as the distance that the positioning nut 35 moves downward on the first threaded rod 32. The end of the first threaded rod 32 furthest from the motor 31 is fixedly connected to a clamping plate 36 that holds the lifting plate 4. The clamping plate 36 prevents the lifting plate 4 from falling off the first threaded rod 32 and limits the movement range of the lifting plate 4. The first threaded rod 32 spirally passes through the middle of the lifting plate 4. Both ends of the lifting plate 4 are provided with U-shaped clamping seats 44 that hold the U-shaped brackets 3. The U-shaped clamping seats 44 hold the U-shaped brackets 3, restricting the rotation of the lifting plate 4, so that the lifting plate 4 moves only in the vertical direction under the drive of the first threaded rod 32, ensuring the stability of the adjustment process of the movable straightening roller 12. The other end of the U-shaped clamping seat 44 is fixedly connected to the end of the corresponding L-shaped limiting plate 41.

[0028] In addition, such as Figures 1 to 3 As shown, both ends of the movable straightening roller 12 are rotatably connected to a second threaded rod 42. The second threaded rod 42 is driven to move spirally by rotating the turntable handle 43, thereby manually fine-tuning the position of the movable straightening roller 12. The end of the second threaded rod 42 away from the movable straightening roller 12 spirally passes through the straightening bracket 11 and is fixedly connected to the turntable handle 43. The turntable handle 43 is held and rotated by the operator, driving the second threaded rod 42 to move spirally, thereby realizing the manual fine-tuning of the position of the movable straightening roller 12. The end of the L-shaped limiting plate 41 away from the lifting plate 4 is used to lock the turntable handle 43 and move it downward to the straightening bracket 11.

[0029] It is worth noting that, such as Figures 2 to 4As shown, a positioning mechanism is installed on the lifting mechanism. This positioning mechanism is used to lock the lifting plate 4 upwards. The positioning mechanism includes a flat groove 33 on the first threaded rod 32. The flat groove 33 is used to set a length mark 34, providing a visual and quantitative reference for adjusting the distance between the movable straightening roller 12 and the fixed straightening roller 13. The flat groove 33 has a length mark 34, which indicates a specific length (unit: millimeters), helping the operator accurately control the rotation of the first threaded rod 32, thereby accurately adjusting the distance between the movable straightening roller 12 and the fixed straightening roller 13. A positioning nut 35 is also screwed onto the first threaded rod 32 to lock the lifting plate 4. After the first threaded rod 32 is adjusted to the appropriate position, the positioning nut 35 locks the lifting plate 4, preventing it from moving upwards and fixing the position of the movable straightening roller 12. It also visually indicates how much the distance decreases after the movable straightening roller 12 moves towards the fixed straightening roller 13.

[0030] In this embodiment, when using the aluminum profile straightening device, the aluminum profile body 2 is first sent to the straightening brackets 11 of the straightening machine 1, so that the profile is in the area enclosed by the movable straightening roller 12, the fixed straightening roller 13 and the auxiliary straightening roller 14. The motor 31 on the U-shaped bracket 3 is started, and the output shaft of the motor 31 drives the first threaded rod 32 to rotate. The first threaded rod 32 is screwed with the lifting plate 4, and at the same time, the U-shaped brackets 44 at both ends of the lifting plate 4 engage with the U-shaped bracket 3, restricting the rotation of the lifting plate 4, so that the lifting plate 4 moves in the vertical direction.

[0031] When it is necessary to adjust the distance between the movable straightening roller 12 and the fixed straightening roller 13, the distance between them is initially at its maximum. At this time, the positioning nut 35 is located at the top of the first threaded rod 32 and abuts against the U-shaped bracket 3. Then, the motor 31 is started to rotate the first threaded rod 32, thereby moving the lifting plate 4 on the length mark 34 to abut against the clamping plate 36. The lifting plate 4 also drives multiple L-shaped limit plates 41 away from the corresponding turntable handles 43. Finally, the positioning nut 35 is rotated to move to the specified distance according to the plane groove 33, and the bottom end of the positioning nut 35 points to the corresponding length mark 34 on the plane groove 33. At this time, the distance that the positioning nut 35 moves on the plane groove 33 is equal to the reduced distance between the movable straightening roller 12 and the fixed straightening roller 13. Then the motor 31 can be started, so that the lifting plate 4 drives multiple L-shaped limit plates 41 to move to abut the positioning nut 35. Then rotate each pair of turntable handles 43. Since the turntable handles 43 are spirally connected to the straightening bracket 11, the distance between the corresponding movable straightening roller 12 and the fixed straightening roller 13 can be adjusted to the specified position by a pair of turntable handles 43, which is convenient and quick.

[0032] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
