[0002] Aluminum alloy profiles have been widely used in aviation, aerospace, automobiles, machinery manufacturing, ships, construction, decoration, and the chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum alloy welded structural parts has been increasing day by day. When bending aluminum profiles, a bending device is required.

[0003] After retrieval, the aluminum profile bending device with the publication number CN217018107U is disclosed. By setting mechanisms such as a T-shaped slideway, a T-shaped slider, a first spring, a second spring, a first guide plate, a second guide plate, a female die, and a male die, it can facilitate the bending of aluminum profiles and at the same time facilitate the removal of the bent aluminum profiles.

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0028] An angle-adjustable aluminum profile bending device includes a base 1. An installation plate 2 is fixedly arranged on the upper side of the base 1. Two groups of installation blocks 3 are movably arranged on the upper side of the installation plate 2. Installation grooves 4 are respectively formed through the inner sides of the two groups of installation blocks 3. A positioning frame 5 is movably arranged inside the installation grooves 4. Two fixed cylinders 6 are fixedly arranged inside the installation grooves 4. Moving rods 7 are respectively movably inserted into the two fixed cylinders 6. The moving rods 7 movably penetrate through the fixed cylinders 6 and extend to the outside. The outer ends of the moving rods 7 located outside the fixed cylinders 6 are fixedly connected to the positioning frame 5. A spring 8 is arranged inside the fixed cylinder 6. One end of the spring 8 is connected to the fixed cylinder 6, and the other end of the spring 8 is connected to the moving rod 7. A fixed frame 9 is fixedly arranged on the upper side of the installation plate 2. An electric push rod 10 is arranged under the fixed frame 9. One end of the electric push rod 10 is connected to the fixed frame 9, and a bending head 11 is arranged at the other end of the electric push rod 10. The spring 8 does not deform in its initial state. When limiting the aluminum profile, it is necessary to move the positioning frame 5 upward. When the positioning frame 5 moves upward, it will drive the moving rod 7 to compress the spring 8, causing the spring 8 to deform. Subsequently, through the release of the elastic potential energy of the spring 8, the positioning frame 5 can be driven to quickly limit the aluminum profile, improving the convenience of limiting the aluminum profile.

[0029] Specifically, a slider 12 is fixedly arranged on the lower side of the installation block 3. A chute 13 for docking the slider 12 is formed on the upper side of the installation plate 2. A connecting rod 14 is fixedly arranged on the outer side of the slider 12. The connecting rod 14 movably penetrates through the installation plate 2 and extends to the outside. A threaded surface 15 is arranged on the outer part of the connecting rod 14 located outside the installation plate 2. A wing nut 16 is threadedly sleeved on the outer side of the threaded surface 15. When moving the installation block 3, the slider 12 is limited to slide in the chute 13. While facilitating the movement of the installation block 3, the installation block 3 can be quickly fixed by tightening the wing nut 16, ensuring the use stability of the installation block 3 and improving the use flexibility of the installation block 3.

[0030] Furthermore, a threaded rod 17 is rotatably arranged inside the positioning frame 5. Two sections of threads with opposite directions are arranged on the outer side of the threaded rod 17. Threaded blocks 18 are respectively sleeved on the two sections of threads with opposite directions on the outer side of the threaded rod 17. L-shaped blocks 19 are fixedly arranged on the outer sides of the two groups of threaded blocks 18. Two groups of U-shaped frames 20 are fixedly arranged inside the L-shaped blocks 19. Multiple groups of rollers 21 are respectively rotatably arranged inside the two groups of U-shaped frames 20. The two sides and the outside of the aluminum profile can be limited by the multiple groups of rollers 21, avoiding the situation of deviation during the bending process of the aluminum profile. At the same time, when moving the aluminum profile, the rollers 21 are driven to rotate, thus facilitating the loading and unloading of the aluminum profile.

[0031] It should be noted that the threaded rod 17 movably penetrates through the positioning frame 5 and extends to the outside, and a hand disc 22 is fixedly arranged on the outer side of the threaded rod 17 at the part located outside the positioning frame 5. A plurality of anti-slip grooves are arranged on the outer side of the hand disc 22, and the anti-slip grooves can improve the friction force of the hand disc 22, making it more convenient to rotate the hand disc 22.

[0032] It should be noted that a handle 23 is fixedly arranged on the upper side of the positioning frame 5. By setting the handle 19, it is convenient to lift the positioning frame 5 upward, improving the mobility of the positioning frame 5.

[0033] In addition, two limiting grooves 24 for the docking threaded blocks 18 are formed inside the positioning frame 5. The threaded blocks 18 are limited and slide in the limiting grooves 24. The limiting grooves 24 can limit the threaded blocks 18, so that when the threaded rod 17 is rotated, the threaded blocks 18 can be driven to move parallel to the threaded rod 17, improving the moving stability of the threaded blocks 18.

[0034] Working principle: First, pull the positioning frame 5 upward to drive the movable rod 7 to move inward into the fixed cylinder 6 and compress the spring 8, causing the spring 8 to deform. Then, pass the aluminum profile through the installation groove 4. Next, release the positioning frame 5. The positioning frame 5 is driven to move downward by the resilience of the spring 8. Then, according to the width of the aluminum profile, rotate the hand disc 22 to drive the threaded rod 17 to rotate. At this time, the two threaded blocks 18 sleeved on the outer side of the threaded rod 17 move along the threaded rod 17 and approach each other simultaneously under the limiting action of the limiting grooves 24. When the threaded blocks 18 move, they drive the L-shaped blocks 19 and the rollers 21 to move. The aluminum profile is limited by a plurality of rollers 21. Then, move the two installation blocks 3 to move the aluminum profile to a suitable position. Then, tighten the wing nut 16 to fix the installation block 3. Finally, turn on the electric push rod 10 through an external power source to drive the folding head 11 to move downward, and the folding head moves downward to bend the aluminum profile.
