Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile processing technology, specifically relating to a mold locking structure for bending aluminum profiles. Background Technology

[0002] Aluminum profiles are industrial aluminum extrusions and industrial aluminum alloy profiles. Industrial aluminum profiles are alloy materials with aluminum as the main component. Aluminum rods are melted and extruded to obtain aluminum materials with different cross-sectional shapes. However, the mechanical properties and application fields of the industrial aluminum profiles produced are different depending on the proportion of alloys added.

[0003] When bending aluminum profiles, one or both sides of the profile need to be pushed to achieve the bending. However, during bending, the aluminum profile is subjected to a strong pushing force, which can easily cause displacement during the bending process. This displacement results in the aluminum profile bending in a direction perpendicular to the bending direction, causing the finished aluminum profile to not fit the designed part. Therefore, this application proposes a mold locking structure for bending aluminum profiles. Utility Model Content

[0004] The purpose of this utility model is to provide a mold locking structure for bending aluminum profiles, so as to solve the problem mentioned in the background art that when bending aluminum profiles, the aluminum profiles are subjected to strong thrust, and the applied thrust can easily cause the aluminum profiles to shift during the bending process. The displacement of the aluminum profiles will cause the aluminum profiles to bend in the direction perpendicular to the bending direction, which will result in the finished aluminum profiles after bending not being able to fit the designed parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold locking structure for bending aluminum profiles, including a bending frame, a fixed platform and a driving platform are provided on the bending frame, the fixed platform is installed on the bending frame, the driving platform is movably connected to the bending frame, a driving roller is provided on the driving platform, and an upper pressure roller is provided on the bending frame.

[0006] The bending frame is equipped with a drive unit, one end of which is movably connected to the bending frame, and the output end of which is movably connected to the drive table.

[0007] The drive platform is provided with a first locking plate, a second locking plate, a guide plate, and a power mechanism. The first locking plate is installed on the drive platform, the second locking plate is slidably engaged with the drive platform, and the power mechanism is connected to the second locking plate. The power mechanism is used to adjust the distance between the second locking plate and the first locking plate.

[0008] There are two guide plates, one of which is installed on the first locking plate and the other is installed on the second locking plate.

[0009] Preferably, a lower pressure roller is provided on the fixed platform.

[0010] Preferably, the guide plate is provided with a baffle and a vertical plate, with the vertical plate abutting against the drive platform.

[0011] Preferably, the baffle is mounted on the guide plate.

[0012] Preferably, the power mechanism includes a threaded rod and a drive motor, the output shaft of the drive motor is connected to the threaded rod, the drive motor is mounted on a first locking plate, and the threaded rod is connected to a second locking plate by a thread.

[0013] Preferably, the drive platform is provided with a guide rail, and the second locking plate is provided with a sliding groove that cooperates with the guide rail.

[0014] Preferably, the fixed platform is provided with a first positioning plate, a second positioning plate, a positioning motor, a drive rod, a pressure rod, and a sliding sleeve. The first positioning plate is installed on the fixed platform, and the second positioning plate is slidably engaged with the fixed platform.

[0015] Preferably, the drive rod is connected to the output end of the positioning motor, and the drive rod is connected to the second positioning plate by a thread.

[0016] Preferably, a pressure bar is installed on the second positioning plate, and the pressure bar presses against the upper end surface of the aluminum profile body.

[0017] Preferably, the sliding sleeve is mounted on the first positioning plate, and the sliding sleeve is in sliding engagement with the pressure rod.

[0018] Beneficial effects:

[0019] This utility model provides a mold locking structure for bending aluminum profiles. The power mechanism is used to adjust the distance between the second locking plate and the first locking plate, so that the second locking plate moves closer to the first locking plate, thereby pushing the aluminum profile body to press against the first locking plate, completing the locking of the position of the aluminum profile body. Before bending, the power mechanism needs to be activated to push the second locking plate to move, leaving a certain space between the second locking plate and the aluminum profile body. In this way, when the aluminum profile body is bent, its relative displacement with the second locking plate on the drive table will not be hindered by the friction of the second locking plate. When bending, the first locking plate, the second locking plate, and the guide plate can provide guidance for the bending of the aluminum profile body, preventing the aluminum profile body from tilting during the bending process.

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figures 1-5 As shown in the figure, the present invention provides a mold locking structure for bending aluminum profiles, including a bending frame 1, a fixed platform 2 and a driving platform 3. The fixed platform 2 is installed on the bending frame 1, and the driving platform 3 is movably connected to the bending frame 1. The driving platform 3 is provided with a driving roller 15, the fixed platform 2 is provided with a lower pressure roller 16, and the bending frame 1 is provided with an upper pressure roller 14. The driving platform 3 can rotate around the bending frame 1, thereby pushing the aluminum profile body 4 located on the driving platform 3 to achieve the purpose of bending the aluminum profile body 4.

[0029] Specifically, a drive unit 13 is provided on the bending frame 1. The drive unit 13 is a hydraulic cylinder. One end of the drive unit 13 is movably connected to the bending frame 1, and the output end of the drive unit 13 is movably connected to the drive table 3.

[0030] When the drive unit 13 is started, it can push the drive table 3 to rotate around the bending frame 1. When the drive table 3 is lifted, the drive roller 15 on the drive table 3 will push one side of the aluminum profile body 4, thereby causing the aluminum profile body 4 to bend upward around the pressure roller 14, thus realizing the bending of the aluminum profile body 4.

[0031] In order to lock the position of the aluminum profile body 4 before bending, a first locking plate 5, a second locking plate 8, a guide plate 10, and a power mechanism are provided on the drive table 3. The first locking plate 5 is installed on the drive table 3, the second locking plate 8 is slidably engaged with the drive table 3, and the power mechanism is connected to the second locking plate 8. The power mechanism is used to adjust the distance between the second locking plate 8 and the first locking plate 5, so that the second locking plate 8 moves closer to the first locking plate 5, thereby pushing the aluminum profile body 4 to press the aluminum profile body 4 onto the first locking plate 5, thus completing the locking of the position of the aluminum profile body 4. Before bending, the power mechanism needs to be activated to push the second locking plate 8 to move, leaving a certain space between the second locking plate 8 and the aluminum profile body 4. In this way, when the aluminum profile body 4 is relatively displaced with the second locking plate 8 on the drive table 3 during the bending process, it will not be hindered by the friction of the second locking plate 8.

[0032] Specifically, there are two guide plates 10. One guide plate 10 is installed on the first locking plate 5, and the other guide plate 10 is installed on the second locking plate 8. The guide plate 10 is provided with a baffle 11 and a vertical plate 12. The vertical plate 12 abuts against the drive table 3, and the baffle 11 is installed on the guide plate 10.

[0033] More specifically, the power mechanism includes a threaded rod 7 and a drive motor 6. The output shaft of the drive motor 6 is connected to the threaded rod 7, and the two can be connected by a coupling. The drive motor 6 is mounted on the first locking plate 5, and the threaded rod 7 is connected to the second locking plate 8 by threads.

[0034] It should be noted that the drive platform 3 is equipped with a guide rail 9, and the second locking plate 8 is equipped with a sliding groove that cooperates with the guide rail 9.

[0035] The guide plate 10 can provide guidance for the bending of the aluminum profile body 4, and prevent the aluminum profile body 4 from tilting during the bending process.

[0036] To prevent the upper part of the aluminum profile body 4 from bending due to the pressure of the drive roller 15 during the bending process, the fixed platform 2 is provided with a first positioning plate 17, a second positioning plate 18, a positioning motor 19, a drive rod, a pressure rod 20, and a sliding sleeve 21. The first positioning plate 17 is installed on the fixed platform 2, the second positioning plate 18 is slidably engaged with the fixed platform 2, the drive rod is connected to the output end of the positioning motor 19, and the two can be connected by a coupling. The drive rod is threadedly connected to the second positioning plate 18, the pressure rod 20 is installed on the second positioning plate 18, and the sliding sleeve 21 is installed on the first positioning plate 17, and the sliding sleeve 21 is slidably engaged with the pressure rod 20. The pressure rod 20 presses against the upper surface of the aluminum profile body 4. During the extrusion of the aluminum profile body 4 by the drive roller 15, components such as the first positioning plate 17 and the second positioning plate 18 are set at the fixed table 2 to position the aluminum profile body 4. Before bending the aluminum profile body 4, there also needs to be a gap between the second positioning plate 18 and the aluminum profile body 4. The second positioning plate 18 and the fixed table 2 can only slide relative to each other in a direction perpendicular to the aluminum profile body 4. The pressure bar 20 on the upper side of the aluminum profile body 4 can extrude the aluminum profile body 4, so that one side of the fixed table 2 will not bend during the bending process of the aluminum profile body 4, ensuring that the bending degree of the aluminum profile body 4 meets the requirements.

[0037] In summary, this utility model embodiment provides a mold locking structure for bending aluminum profiles. The power mechanism is used to adjust the distance between the second locking plate 8 and the first locking plate 5, so that the second locking plate 8 moves closer to the first locking plate 5, thereby pushing the aluminum profile body 4 to press the aluminum profile body 4 onto the first locking plate 5, completing the locking of the position of the aluminum profile body 4. Before bending, the power mechanism needs to be activated to push the second locking plate 8 to move, leaving a certain space between the second locking plate 8 and the aluminum profile body 4. In this way, when the aluminum profile body 4 is bent, it will not be hindered by the friction of the second locking plate 8 when it is relatively displaced with the second locking plate 8 on the drive table 3. The guide plate 10 can provide guidance for the bending of the aluminum profile body 4 and prevent the aluminum profile body 4 from tilting during the bending process.

[0038] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
