Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and more specifically, to an aluminum profile straightening device. Background Technology

[0002] With my country's large-scale infrastructure investment and rapid industrialization, the output and consumption of aluminum profiles have grown rapidly, making my country the world's largest aluminum profile production base and consumer market. Aluminum profiles are non-ferromagnetic, which is an important characteristic for the electrical and electronics industries. Aluminum profiles are not spontaneously combustible, which is important for applications involving loading, unloading, or contact with flammable and explosive materials. Aluminum profiles have excellent machinability. Aluminum alloy building profiles have advantages such as high strength, light weight, corrosion resistance, good decorative properties, long service life, and rich colors. Building aluminum materials are building products made of aluminum and aluminum alloy materials. Aluminum alloys are divided into two main categories according to their production methods: cast aluminum alloys and wrought aluminum alloys. When straightening aluminum profiles, an aluminum profile straightening device is required.

[0003] Most existing straightening devices can only effectively straighten rectangular aluminum profiles, but cannot effectively straighten cylindrical aluminum profiles. This significantly reduces the applicability of the straightening devices. When it is necessary to straighten cylindrical aluminum profiles, specialized equipment is required, which not only reduces the straightening efficiency and effect of cylindrical aluminum profiles, but also increases the production cost for producers and reduces the overall practicality and flexibility of the straightening devices.

[0004] Compared with Chinese Patent Publication No. CN220879979U, this utility model discloses a stable straightening device for architectural aluminum profiles, relating to the field of aluminum profile processing technology. It includes an L-shaped support platform, with two symmetrical N-shaped frames fixedly connected to the upper surface of the L-shaped support platform. Each of the inner top walls of the two N-shaped frames is equipped with an electric push rod, and the output ends of both electric push rods are fixedly connected to pressure plates. A central limiting mechanism is provided below each of the two pressure plates, and each central limiting mechanism includes a motor and two side limiting plates. A straightening frame is slidably connected to the inner wall of the L-shaped support platform. An upper straightening mechanism, including an electric push rod, is provided inside the straightening frame. Two symmetrical side straightening mechanisms are also provided inside the straightening frame. By using the central limiting mechanisms, the device can pre-position the architectural aluminum profile at the center of the L-shaped support platform before straightening, resulting in a more ideal straightening effect and improved efficiency.

[0005] The above solution can effectively straighten rectangular aluminum profiles, but it still cannot effectively fix and straighten cylindrical aluminum profiles, thus failing to solve the problems mentioned in the background art.

[0006] Therefore, those skilled in the art have provided an aluminum profile straightening device to solve the problems mentioned in the background art. Utility Model Content

[0031] 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.

[0032] Please see Figure 1 - Figure 7 As shown, this embodiment provides an aluminum profile straightening device, including a base 1, and further comprising:

[0033] Support platform 2 is fixedly connected to the upper surface of base 1;

[0034] The movable frame 3 is symmetrically arranged above the support platform 2. The upper surface of the movable frame 3 is symmetrically provided with the mounting frame 4. The upper surface of the mounting frame 4 is provided with a through mounting hole for mounting the electric telescopic rod 5. The telescopic end of the electric telescopic rod 5 is fixedly connected to the mounting frame 6. The mounting frame 6 is provided with the mounting block 37 inside. The bottom of the mounting block 37 is fixedly connected to the upper clamp 7.

[0035] The first fixing component is symmetrically arranged on the outside of the mounting frame 6;

[0036] The fixed frame 23 is fixedly connected to the outside of the mounting bracket 4. The fixed frame 23 is provided with a connecting block 28 inside, and a lower clamp 8 is fixedly connected to the outside of the connecting block 28.

[0037] The second fixing component is located outside the fixing frame 23;

[0038] The tensioning assembly is located at the bottom of the support platform 2;

[0039] The straightening component is reinforced and installed on the upper surface of the support platform 2.

[0040] The working principle described above is as follows: When straightening aluminum profiles is required, the two ends of the aluminum profile are first fixed by the cooperation between the upper clamp 7 and the lower clamp 8. After the aluminum profile is fixed, the stretching component starts to operate, and the aluminum profile can be effectively stretched and straightened by the stretching component. During the operation of the stretching component, the reinforcing straightening component will also start to operate simultaneously. At this time, the reinforcing straightening component can further improve the straightening effect of the aluminum profile. Through the setting of the first and second fixing components, it is convenient for the staff to change the specifications and shapes of the upper clamp 7 and the lower clamp 8 according to the different types of aluminum profiles. Thus, the upper clamp 7 and the lower clamp 8 can effectively fix rectangular or cylindrical aluminum profiles, thereby enabling the device as a whole to effectively straighten aluminum profiles of different specifications and shapes without the need for the producer to use additional straightening equipment to straighten aluminum profiles of different specifications and shapes. On the one hand, it reduces the producer's production costs, and on the other hand, it can effectively improve the straightening efficiency of aluminum profiles of different specifications and shapes, while also effectively improving the overall practicality and flexibility of the device.

[0041] To effectively fix the upper clamp 7, the first fixing component includes support blocks 29 symmetrically arranged outside the mounting frame 6. Connecting rods 30 are fixedly connected to the outside of the support blocks 29, and a limiting plate 31 is fixedly connected to the other end of each connecting rod 30. A movable plate 32 is slidably connected to the outside of every two connecting rods 30. A return spring 33 is sleeved on the outside of the connecting rod 30, and the return spring 33 abuts against the movable plate 32 and the limiting plate 31. A pull ring is fixedly connected to one side of the movable plate 32, and insert rods 34 are symmetrically arranged on the other side of the movable plate 32. Guide grooves for the insert rods 34 are provided inside both the mounting frame 6 and the mounting block 37. A bellows cover 35 is sleeved on the outside of the connecting rod 30, and both ends of the bellows cover 35 are respectively connected to the movable plate 32 and the limiting plate 31. The upper clamp 7 is fixedly connected to the opposite side of the connecting rod 30. When it is necessary to fix the upper clamp 7, simply pull the pull ring first. The pull ring will drive the moving plate 32 to move synchronously outside the connecting rod 30. During the movement of the moving plate 32, it will squeeze the return spring 33. The moving plate 32 will also drive the insertion rod 34 to move synchronously. Then, insert the mounting block 37 into the interior of the mounting frame 6, and then release the pull ring. At this time, the return spring 33 will return to its original position, driving the moving plate 32 and the insertion rod 34 to move synchronously. When the insertion rod 34 is inserted into the guide groove inside the mounting block 37, the mounting block 37 and the mounting frame 6 can be fixed. At this time, the upper clamp 7 can be fixedly installed. At the same time, it is convenient for the staff to change the specifications and shape of the upper clamp 7 (e.g., Figure 4 As shown, when straightening cylindrical aluminum profiles, the shape of the upper clamp 7 can be changed.

[0042] Considering that after the upper clamp 7 is changed, the lower clamp 8 also needs to be changed simultaneously, the second fixing component includes a fixing sleeve 24 fixedly connected to the outside of the fixing frame 23. A fixing rod 25 is provided inside the fixing sleeve 24. A pull plate is fixedly connected to one end of the fixing rod 25. An abutment plate 26 is fixedly connected to the outside of the fixing rod 25. An abutment spring 27 is sleeved on the outside of the fixing rod 25, and the abutment spring 27 abuts against the abutment plate 26 and the fixing sleeve 24. Guide grooves for the movement of the fixing rod 25 are provided on the contact surfaces of the fixing sleeve 24 and the fixing frame 23. A guide groove for the movement of the fixing rod 25 is also provided inside the connecting block 28. When it is necessary to adjust the lower clamp 8... During the fixed installation process, simply pull the pull plate first. The pull plate will then move the fixing rod 25 synchronously, which in turn moves the contact plate 26 synchronously. During the movement of the contact plate 26, it will simultaneously compress the contact spring 27. Then, insert the connecting block 28 into the fixed frame 23, and release the pull plate. The contact spring 27 will then return to its original position, moving the contact plate 26 and the fixing rod 25 synchronously. When the fixing rod 25 is inserted into the guide groove inside the connecting block 28, the connecting block 28 and the fixed frame 23 are fixed together. This allows for the fixed installation of the lower clamp 8 and facilitates easy replacement of its specifications and shape by the operator. Figure 4 As shown, when straightening cylindrical aluminum profiles, the material is replaced with... Figure 4 The lower clamp 8 shown can be used to fix aluminum profiles of different shapes and specifications, thus enabling the device to effectively straighten aluminum profiles of different shapes and specifications.

[0043] To effectively straighten the aluminum profile, the tensioning assembly includes an adjusting plate 9 fixedly connected to the bottom of the support platform 2. A first motor 13 is fixedly connected to one side of the adjusting plate 9. The output shaft of the first motor 13 is fixedly connected to a bidirectional threaded rod 14 via a coupling. The other end of the bidirectional threaded rod 14 is rotatably connected to the inner wall of the adjusting plate 9. Threaded blocks 15 are symmetrically arranged on the outside of the bidirectional threaded rod 14, and connecting plates 16 are symmetrically arranged on the outside of the threaded blocks 15. Guide grooves for the connecting plates 16 to move are opened on the outside of the adjusting plate 9. The upper surfaces of the multiple connecting plates 16 are connected to the moving plate 17 via an upper plate 17. The bottom of the moving frame 3 is fixedly connected, and the upper surface of the support platform 2 is provided with a guide groove for the upper plate 17 to move. After both ends of the aluminum profile are fixed, the first motor 13 starts to run. At this time, the first motor 13 will drive the bidirectional threaded rod 14 to rotate synchronously, and the threaded block 15 will move synchronously outside the bidirectional threaded rod 14, driving the connecting plate 16 to move synchronously. The connecting plate 16 then drives the upper plate 17 and the moving frame 3 to move synchronously to both sides. The moving frame 3 then drives the upper clamp 7 and the lower clamp 8 to move synchronously. At this time, the aluminum profile can be effectively stretched and straightened.

[0044] To further improve the straightening effect of aluminum profiles, the straightening assembly includes a transmission plate 10 fixedly connected to the upper surface of the support platform 2. A second motor 19 is fixedly connected to the outside of the transmission plate 10. The output shaft of the second motor 19 is fixedly connected to a lead screw 20 via a coupling. The other end of the lead screw 20 is rotatably connected to the inner wall of the transmission plate 10. A threaded plate 21 is threadedly connected to the outside of the lead screw 20. A guide groove for the threaded plate 21 to move is provided on the upper surface of the transmission plate 10. Connecting frames 18 are symmetrically provided on the outside of the threaded plate 21. Insert plates 38 are provided inside both connecting frames 18. A straightening frame 11 is fixedly connected to the outside of the insert plates 38. Straightening rollers 12 are rotatably connected to the inner wall of the straightening frame 11 at equal intervals. When straightening aluminum profiles is required, simply pass the aluminum profile through the inside of the straightening frame 11, and then fix both ends of the aluminum profile. After the two ends of the aluminum profile are fixed, the stretching assembly starts to operate. During the operation of the stretching assembly, the second motor 19 also starts to operate synchronously. At this time, the second motor 19 drives the lead screw 20 to rotate synchronously, and the threaded plate 21 moves synchronously outside the lead screw 20, driving the connecting frame 18 and the insert plate 38 to move synchronously. The insert plate 38 then drives the straightening frame 11 to move synchronously, and the straightening frame 11 then drives the straightening roller 12 to move synchronously. At this time, the straightening effect of the aluminum profile can be further improved by the cooperation between the straightening frame 11 and the straightening roller 12 (e.g., Figure 4 As shown, when straightening cylindrical aluminum profiles, the straightening frame 11 can be replaced with a cylindrical one. The inner wall of the cylindrical straightening frame 11 is provided with balls 22 at equal intervals. At this time, the cylindrical aluminum profile can be effectively straightened by the cooperation between the balls 22 and the cylindrical straightening frame 11.

[0045] In addition, to facilitate the replacement and adjustment of the specifications and shape of the straightening frame 11 by the staff, an inner plate 39 is fixedly connected inside the insert plate 38. Damping rods 40 are fixedly connected to both the upper and lower surfaces of the inner plate 39. An arc-shaped locking block 41 is fixedly connected to the telescopic end of the damping rod 40. A compression spring 42 is sleeved on the outside of the damping rod 40, and the compression spring 42 abuts against the arc-shaped locking block 41 and the inner plate 39. Guide grooves for the arc-shaped locking block 41 to move are provided on the upper and lower surfaces of the connecting frame 18 and the insert plate 38. When the straightening frame 11 needs to be fixedly installed, simply insert the insert plate 38 into the interior of the connecting frame 18. At this time, the insert plate 38 will drive the arc-shaped locking block 41 to move synchronously. When the locking block 41 enters the interior of the connecting frame 18, it will be squeezed. At this time, the arc-shaped locking block 41 will squeeze the damping rod 40 and the compression spring 42 simultaneously. When the insert plate 38 moves the arc-shaped locking block 41 into the guide grooves on the upper and lower surfaces of the connecting frame 18, the compression spring 42 resets and moves the arc-shaped locking block 41 synchronously. When the arc-shaped locking block 41 is inserted into the guide grooves on the upper and lower surfaces of the connecting frame 18, the insert plate 38 and the connecting frame 18 can be fixed. At this time, the straightening frame 11 can be fixedly installed. At the same time, it is convenient for the staff to change and adjust the specifications and shapes of the straightening frame 11 according to the different specifications and shapes of the aluminum profiles, which effectively improves the overall practicality of the device.
