Description

Technical Field

[0001] The present application relates to the technical field of aluminum profile production, and in particular to an aluminum profile straightening device. Background Art

[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminum rods. Aluminum profiles have the advantages of good corrosion resistance, electrical conductivity, formability, recyclability and machinability. Aluminum profiles can be used in the field of building prefabricated parts, especially doors and windows, steel frame house foundations, etc., and have a wide range of applications.

[0003] In the related art, during the cooling process after forming, the aluminum profile will still be affected by equipment or other external factors, causing the aluminum profile to deform.

[0004] With respect to the above-mentioned related technologies, when multiple aluminum profiles are used for assembly, the flatness of the surface of the aluminum profiles is required to be high, and the aluminum profiles need to be straightened. Summary of the invention

[0005] In order to straighten aluminum profiles, the present application provides an aluminum profile straightening device.

[0006] The aluminum profile straightening device provided in this application adopts the following technical solution:

[0007] A straightening device for aluminum profiles comprises a frame, on which an active roller is arranged horizontally, with the axis direction of the active roller parallel to the width direction of the frame, the active roller and the frame being rotatable around their own axis directions, the frame being provided with a driving motor for driving the active roller to rotate, a pressure plate being arranged on one side of the active roller along the length direction of the frame, the pressure plate sliding on the frame along the vertical direction, a hydraulic cylinder being arranged on the pressure plate, the piston rod of the hydraulic cylinder being fixed on the pressure plate, the cylinder body of the hydraulic cylinder being fixed on the frame, and a horizontal straightening component for straightening the two horizontal side surfaces of the aluminum profile being further arranged on the side of the pressure plate away from the active roller.

[0008] By adopting the above technical solution, the staff puts one end of the aluminum profile under the active roller, and the driving motor drives the active roller to rotate continuously around the axis of the active roller. The outer side of the active roller contacts the upper side of the aluminum profile, and the aluminum profile is driven to move along the length direction of the frame through friction. When the aluminum profile moves to the lower side of the pressure plate, the hydraulic cylinder piston rod drives the pressure plate to move downward in the vertical direction, thereby impacting the upper side of the aluminum profile, thereby achieving straightening of the upper and lower sides of the aluminum profile. The aluminum profile continues to move forward, and the horizontal straightening component horizontally straightens the aluminum profile on both sides along the width direction of the frame.

[0009] Preferably, a hot air cylinder is respectively arranged on both sides of the pressing plate along the width direction of the frame, and the two hot air cylinders are symmetrically arranged on both sides of the pressing plate.

[0010] By adopting the above technical solution, the hot air cylinders on both sides heat the aluminum profile in the middle, so that the pressure plate only needs to apply a small force to the aluminum profile to cause the aluminum profile to deform, which helps to improve the straightening efficiency of the entire straightening assembly.

[0011] Preferably, a guide assembly is further provided on the frame, and the guide assembly is located on the side of the active roller away from the pressure plate.

[0012] By adopting the above technical solution, the guiding assembly helps to position the aluminum profile that has just entered the frame, helps to ensure that the aluminum profile is located on the lower side of the pressure plate, and thus helps to ensure the straightening effect of the straightening assembly.

[0013] Preferably, the guide assembly includes a guide roller arranged corresponding to the bottom groove of the aluminum profile, the guide roller is arranged vertically, and a guide shaft is coaxially arranged on the guide roller, the guide roller and the guide shaft are rotatably connected around their own axis directions, the frame includes a bottom plate, the guide shaft penetrates the bottom plate along its own axis direction, the guide shaft and the bottom plate slide along the vertical direction, an embedding groove is provided on one side in the length direction of the bottom plate, the embedding groove penetrates the bottom plate along the length direction of the bottom plate, a rotating wheel is provided in the embedding groove, the guide shaft penetrates the rotating wheel along its own axis direction and is threadedly connected to the rotating block.

[0014] By adopting the above technical solution, during the feeding process, the staff can embed the guide roller into the groove at the bottom of the aluminum profile. When the active roller drives the aluminum profile to move, the guide roller will limit the aluminum profile within a certain range. The staff can adjust the position of the guide roller in the vertical direction by rotating the rotating wheel protruding from the embedded groove, and the rotating wheel can slide the guide shaft in the vertical direction through the thread. This helps to adjust the guide roller according to the grooves on the lower side of different aluminum profiles. This helps to improve the adaptability of the entire straightening device.

[0015] The locking device is configured to lock the locking plate, wherein the locking plate has a first locking mechanism, the first locking mechanism being configured to lock the locking plate, the second locking mechanism being configured to lock the locking plate, and the second locking mechanism being configured to lock the locking plate.

[0016] By adopting the above technical solution, two opposite limiting rollers are pressed against the outer side of the aluminum profile, thereby limiting the aluminum profile. Before using the active roller, the staff turns the first rotating hand wheels on both sides to move the two limiting rollers to the side away from each other, and places the aluminum profile on the bottom plate. The staff turns the two first rotating hand wheels to make the two limiting rollers press against the outer side of the aluminum profile respectively. When straightening, the staff inserts the aluminum profile from the side of the limiting roller away from the active roller, so that the outer side of the aluminum profile abuts against the outer side of the two limiting rollers. In this way, it helps to improve the stability of the aluminum profile when it moves on the frame while improving the practicality of the straightening device.

[0017] Preferably, the middle part of any of the limiting rollers contracts inwardly, so that both ends of the limiting roller in the axial direction form conical surfaces, and any of the conical surfaces abuts against the arc chamfers of the four corners of the aluminum profile.

[0018] By adopting the above technical solution, the contact area between the limiting roller and the aluminum profile is reduced before the pressure plate performs straightening operation on the aluminum profile, thereby reducing the damage of the limiting roller to the aluminum profile while ensuring the limiting effect.

[0020] By adopting the above technical solution, in actual work, after the aluminum profile passes through the pressing plate, the two rows of abutment rollers are respectively pressed against the two sides of the aluminum profile, and the multiple abutment rollers with staggered design are pressed against the two sides of the aluminum profile along the width direction of the bottom plate in turn, thereby realizing the straightening of the aluminum profile. The staff can adjust each second rotating hand wheel to change the force applied by the abutment roller on the aluminum profile, thereby realizing the straightening of the aluminum profile.

[0021] Preferably, the frame is also provided with an adjustment component for adjusting the position of the active roller in the vertical direction.

[0022] By adopting the above technical solution, by changing the relative position of the active roller in the vertical direction, the active roller can drive the aluminum profiles of different heights to move. In this way, it helps to improve the adaptability of the straightening device.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses an aluminum profile straightening device.

[0035] See also Figure 1-Figure 2The aluminum profile straightening device includes a frame 1, which includes a bottom plate 11, and the length direction of the bottom plate 11 is consistent with the length direction of the frame 1. The bottom plate 11 is sequentially provided with a guide assembly 2, a limit assembly 3, an active roller 4, a pressure plate 6 and a horizontal straightening assembly 8 along the length direction. The active roller 4 is horizontally arranged, and the axis direction of the active roller 4 is parallel to the width direction of the bottom plate 11. The active roller 4 is rotatably arranged on the frame 1. A driving motor 41 is also fixed on the frame 1, and the output shaft of the driving motor 41 is coaxially fixed with the active roller 4. The pressure plate 6 is horizontally arranged, and a hydraulic cylinder 61 is also arranged on the frame 1. The cylinder body of the hydraulic cylinder 61 is fixedly connected to the frame 1, and the piston rod of the hydraulic cylinder 61 is fixedly connected to the upper side of the pressure plate 6. During the straightening operation, the staff puts the aluminum profile 100 into the frame 1 from the end close to the guide assembly 2, and the guide assembly 2 and the limit assembly 3 will guide and limit the aluminum profile 100. The driving motor 41 drives the active roller 4 to rotate, and the outer side of the active roller 4 abuts against the upper side of the aluminum profile 100, driving the aluminum profile 100 to move along the length direction of the bottom plate 11. When the aluminum profile 100 moves to the lower side of the pressing plate 6, the piston rod of the hydraulic cylinder 61 drives the pressing plate 6 to move downward, thereby pressing on the aluminum profile 100 to achieve the straightening operation in the vertical direction. The aluminum profile 100 moves forward again and is straightened in the horizontal direction through the horizontal straightening component 8. In this way, the straightening operation of the aluminum profile 100 is achieved in all aspects.

[0036] Hot air cylinders 7 are respectively arranged on both sides of the pressing plate 6 along the width direction of the bottom plate 11, and the air outlets of the two hot air cylinders 7 are arranged opposite to each other and both point to the lower side of the pressing plate 6. In actual work, before or during the operation of the pressing plate 6, the hot air cylinders 7 heat the aluminum profile 100 by blowing out hot air, so that the aluminum profile 100 is easier to be straightened, which helps to improve the straightening effect of the straightening device.

[0037] See also Figure 1-Figure 3The guide assembly 2 includes a guide roller 21, which is vertically arranged. The guide roller 21 is arranged corresponding to the groove at the bottom of the aluminum profile 100, and the guide roller 21 is located in the middle of the bottom plate 11. A guide shaft 22 is coaxially arranged on the guide roller 21, and the guide roller 21 is rotatably connected with the guide shaft 22 around its own axis direction. The guide shaft 22 penetrates the bottom plate 11 along its own axis direction, and an embedding groove 12 is provided on the side of the bottom plate 11 close to the guide assembly 2 in the length direction. The embedding groove 12 penetrates the bottom plate 11 along the length direction of the bottom plate 11, and the guide shaft 22 penetrates the embedding groove 12 along its own axis direction. A rotating wheel 23 is arranged in the embedding groove 12, and the rotating wheel 23 is horizontally arranged. The rotating wheel 23 protrudes from the bottom plate 11 along the length direction of the bottom plate 11 on the side close to the guide roller 21. The guide shaft 22 penetrates the rotating wheel 23 along its own axis direction and is threadedly connected with the rotating wheel 23. In actual work, during the loading process, the staff makes the guide roller 21 located in the groove at the bottom of the aluminum profile 100, and the staff turns the rotating wheel 23 to rotate, so that any side of the guide roller 21 abuts against the inner wall of the groove at the bottom of the aluminum profile 100. In this way, it is convenient for the staff to position and limit the aluminum profile 100, ensuring that the aluminum profile 100 is located under the active roller 4 and the pressure plate 6. In this way, it is convenient for the staff to operate and help improve work efficiency.

[0038] The limiting assembly 3 includes a first fixed block 31, which is fixed to one side of the bottom plate 11 in the width direction. A first rotating shaft 32 is arranged on the first fixed block 31, and the first rotating shaft 32 is arranged horizontally. The axis direction of the first rotating shaft 32 is parallel to the direction of the bottom plate 11. The first rotating shaft 32 passes through the first fixed block 31 along its own axis direction and is threadedly connected with the first fixed block 31. A first rotating hand wheel 33 is fixed to the side of the first rotating shaft 32 that is away from the guide roller 21 in the axis direction. A first positioning block 34 is arranged on the side of the first rotating shaft 32 that is close to the guide roller 21 in the axis direction. The first rotating shaft 32 is rotatably connected to the first positioning block 34 around its own axis direction. The first positioning block 34 is slidably matched with the bottom plate 11 in the width direction of the bottom plate 11. A limiting roller 35 is arranged on the side of the first fixed block 31 that is away from the first rotating shaft 32. The limiting roller 35 is arranged vertically and is rotatably connected to the first positioning block 34 along its own axis direction. The middle part of the limiting roller 35 shrinks inwards, so that a conical surface 351 is formed at each end of the limiting roller 35, and any conical surface 351 is pressed against the circular chamfers of the four corners of the aluminum profile 100. Two limiting components 3 are symmetrically arranged on both sides of the bottom plate 11 in the width direction.

[0039] Before installing the aluminum profile 100, the staff rotates the first rotating hand wheels 33 on both sides to move the two limiting rollers 35 to the side away from each other, places the aluminum profile 100 on the bottom plate 11, and then rotates the two first rotating hand wheels 33 to make the two limiting rollers 35 respectively press against the outer side of the aluminum profile 100. The staff inserts the aluminum profile 100 from the side of the limiting roller 35 away from the active roller 4, so that the outer side of the aluminum profile 100 abuts against the outer side of the two limiting rollers 35. When the active roller 4 drives the aluminum profile 100 to move, the limiting components 3 on both sides can improve the stability of the aluminum profile 100 when it moves on the frame 1, thereby helping to ensure the straightening effect. The conical surface 351 helps to reduce the contact area between the limiting roller 35 and the aluminum profile 100 while ensuring the limiting effect, thereby helping to reduce the damage of the limiting roller 35 to the outer surface of the aluminum profile 100.

[0040] See also Figure 1 , Figure 2 and Figure 4 , the frame 1 is also provided with an adjustment component 5, which is located on the upper side of the active roller 4. The adjustment component 5 includes a support frame 52, the length direction of the support frame 52 is parallel to the axis direction of the active roller 4, and the two ends of the axis direction of the active roller 4 are rotatably connected to the support frame 52. A support plate 51 is provided on one side of the length direction of the support frame 52, the support plate 51 is vertically arranged, and the thickness direction of the support plate 51 is parallel to the width direction of the bottom plate 11. A waist-shaped groove 511 is provided on the support plate 51, and the waist-shaped groove 511 penetrates the support plate 51 along the thickness direction of the support plate 51, and the length direction of the waist-shaped groove 511 is vertically arranged. A sliding block 521 is correspondingly provided on the support frame 52, and the sliding block 521 is penetrated in the waist-shaped groove 511 along the thickness direction of the waist-shaped groove 511, and an adjusting nut 54 is also sleeved on the sliding block 521, and the adjusting nut 54 is threadedly connected to the sliding block 521. The thickness direction of the adjusting nut 54 is parallel to that of the supporting plate 51, and the adjusting nut 54 is located on the side of the supporting plate 51 away from the supporting frame 52 along its own thickness direction. The supporting plate 51, the sliding block 521 and the adjusting nut 54 are symmetrically arranged in two groups on both sides of the supporting frame 52 in the length direction.

[0041] A spring 53 is provided on the support frame 52, and a sleeve 522 is sleeved on the outside of the spring 53. One sleeve 522 is provided at each end of the spring 53, and the two sleeves 522 are fixedly connected to the frame 1 and the support frame 52, respectively. The spring 53 can apply vertical downward pressure to the support frame 52, thereby applying vertical downward pressure to the active roller 4, ensuring that the active roller 4 is pressed against the outer surface of the aluminum profile 100. In actual use, the staff places the aluminum profile 100 on the lower side of the active roller 4, loosens the adjusting nuts 54 on both sides, so that the active roller 4 is pressed against the upper side of the aluminum profile 100 under the action of gravity, and the staff tightens the adjusting nuts 54 to fix the active roller 4. The staff adjusts the relative position of the active roller 4 on the frame 1, so that the straightening device is suitable for aluminum profiles 100 of different heights, which helps to improve the practicality of the device.

[0042] See also Figure 1 , Figure 5 , the horizontal straightening assembly 8 includes a second fixed block 81, which is fixed to one side of the bottom plate 11 in the width direction. A second rotating shaft 82 is arranged on the second fixed block 81, and the second rotating shaft 82 is arranged horizontally. The axis direction of the second rotating shaft 82 is parallel to the direction of the bottom plate 11. The second rotating shaft 82 passes through the second fixed block 81 along its own axis direction and is threadedly connected with the second fixed block 81. A second rotating hand wheel 83 is fixed to the side of the second rotating shaft 82 that is away from the guide roller 21 in the axis direction. A second positioning block 84 is arranged on the side of the second rotating shaft 82 that is close to the guide roller 21 in the axis direction. The second rotating shaft 82 is rotatably connected to the second positioning block 84 around its own axis direction. The second positioning block 84 is slidably matched with the bottom plate 11 in the width direction of the bottom plate 11. A contact roller 85 is arranged on the side of the second fixed block 81 that is away from the second rotating shaft 82. The contact roller 85 is arranged vertically and is rotatably connected to the second positioning block 84 along its own axis direction. The horizontal straightening components 8 are evenly spaced along the length direction of the bottom plate 11 to form a row, and the horizontal straightening components 8 are symmetrically arranged in two rows on both sides of the width direction of the bottom plate 11, and the two rows of horizontal straightening components 8 are staggered. When the active roller 4 drives the aluminum profile 100 to move between the abutment rollers 85 on both sides of the width direction of the bottom plate 11 through friction, the abutment rollers 85 on both sides squeeze the aluminum profile 100 in the middle, thereby achieving straightening of the aluminum profile 100. The staff can drive the second positioning block 84 to slide along the width direction of the bottom plate 11 by turning the second rotating hand wheel 83, and change the relative position of any abutment roller 85 on the bottom plate 11. This method helps to change the pressure applied by the abutment roller 85 to the aluminum profile 100, and achieve a better straightening effect.

[0043] A positioning plate 86 is also arranged horizontally on the second positioning block 84, and the two ends of the positioning plate 86 in the length direction are rotatably connected to two adjacent second positioning blocks 84 on one side in the width direction of the bottom plate 11. The staff can more conveniently judge the relative position between the two adjacent second positioning blocks 84 through the inclination angle of the positioning plate 86, thereby changing the pressure applied by different abutting rollers 85 to the aluminum profile 100, so that the straightening device can achieve a better straightening effect.

[0044] See also Figure 1-Figure 5 , a group of active rollers 4 and adjusting components 5 are also arranged on the side of the horizontal straightening component 8 away from the pressing plate 6. When the aluminum profile 100 on the straightening device completes the straightening component, the next active roller 4 will drive the aluminum profile 100 to leave the straightening device through friction, which helps to improve the working efficiency of the straightening device.

[0045] The implementation principle of the aluminum profile straightening device of the embodiment of the present application is as follows: before the straightening operation, the staff first loosens all the adjustment nuts 54 on the two support frames 52, and adjusts the relative position between the active roller 4 and the bottom plate 11 according to the height of the aluminum profile 100. When the aluminum profile 100 is placed on the bottom plate 11, the active rollers 4 on both sides are pressed against the upper side of the aluminum profile 100. The staff then turns the first rotating hand wheels 33 on both sides to make the four conical surfaces 351 of the two limiting rollers 35 press against the circular arc chamfers of the four corners of the aluminum profile 100. During the straightening operation, the staff embeds the guide roller 21 into the groove at the bottom of the aluminum profile 100, and by turning the rotating wheel 23, the outer side surface of the guide roller 21 abuts against the inner side surface of the groove at the bottom of the aluminum profile 100. The circular chamfers of the four corners of the aluminum profile 100 are made to abut against the four conical surfaces 351 of the two limiting rollers 35. The staff pushes the aluminum profile 100 forward so that the upper side of the aluminum profile 100 abuts against the active roller 4. The drive motor 41 is turned on, and the drive motor 41 drives the active roller 4 to rotate, and the aluminum profile 100 is driven forward along the length direction of the bottom plate 11 by friction. The hot air cylinder 7 blows out hot air to heat the aluminum profile 100. The hydraulic cylinder 61 is turned on, and the piston rod of the hydraulic cylinder 61 drives the pressure plate 6 to move downward in the vertical direction. The pressure plate 6 applies a vertical force to the aluminum profile 100, so that the aluminum profile 100 is straightened in the vertical direction to remove possible bending or distortion.

[0046] After completing the vertical straightening, the aluminum profile 100 enters the horizontal straightening area, and the abutting rollers 85 on both sides of the bottom plate 11 in the width direction apply extrusion force to the aluminum profile 100. The staff can adjust the horizontal pressure applied by each abutting roller 85 to the aluminum profile 100 by adjusting the second rotating hand wheel 83, thereby adjusting and correcting the shape of the aluminum profile 100 in the horizontal direction. After the aluminum profile 100 passes through the horizontal straightening area, the active roller 4 on the rear side of the horizontal straightening assembly 8 will drive the aluminum profile 100 to move out of the straightening device, thereby completing the comprehensive straightening of the aluminum profile 100.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
