[0020] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 5 As shown:

[0021] Example 1: A door and window profile bending machine includes a support platform 1. A first sliding frame is slidably arranged on the upper end of the support platform 1 in the left-right direction. A clamping mechanism is provided on the first sliding frame. The first sliding frame slides in the left-right direction, and the clamping mechanism is used to clamp the aluminum profile. A second sliding frame is slidably arranged on the side of the support platform 1 in the front-back direction. The second sliding frame includes a second slider 8. A shifting mechanism is provided between the support platform 1 and the second slider 8. The shifting mechanism controls the second slider 8 to slide in the front-back direction. After the second slider 8 moves to the target position, the shifting mechanism fixes the position of the second slider 8.

[0022] The lower end of the second slider 8 is provided with a drive mechanism 14. The drive mechanism 14 is vertically provided with a drive shaft 15 extending above the second sliding frame. The upper end of the drive shaft 15 is detachably provided with a bending disc 16. The drive mechanism 14 drives the bending disc 16 to rotate through the drive shaft 15. The detachable bending disc 16 makes it easy to replace bending discs 16 of different diameters to adapt to bending requirements of different sizes.

[0023] A telescopic arm 17 is fixedly installed on the drive shaft 15 below the bending disc 16. A first mounting block 18 is connected to the end of the telescopic arm 17. A first limiting plate 19 is provided on the first mounting block 18. The telescopic arm 17 extends and retracts to adjust the distance between the first limiting plate 19 and the bending disc 16. The first limiting plate 19 and the bending disc 16 work together to clamp the aluminum profile.

[0024] A third sliding frame extending in the front-to-back direction is provided on the upper end of the support platform 1 between the first sliding frame and the limiting plate. The third sliding frame includes a second mounting block 20, which slides in the front-to-back direction. A second limiting plate 23 is slidably provided on the rear side of the second mounting block 20 in the left-to-right direction. The second limiting plate 23 slides relative to the second mounting block 20 in the left-to-right direction. The movement of the second mounting block 20 causes the second limiting block to press against the side of the aluminum profile. During the movement of the aluminum profile, the second limiting block moves with the aluminum profile.

[0025] When bending aluminum profiles, replace the bending disc 16 with one of the appropriate size according to the diameter of the required bend radius, adjust the length of the telescopic arm 17, and use the clamping mechanism to hold the aluminum profile. Use the first limiting plate 19 and the bending disc 16 to hold the end of the aluminum profile, and use the second limiting plate 23 to press the middle of the aluminum profile. Then, use the drive mechanism 14 to drive the bending disc 16 and the telescopic arm 17 to rotate synchronously. During the rotation, the first sliding frame drives the aluminum profile to move to the left, and the second limiting plate 23 moves synchronously with the aluminum profile. After bending is completed, control the first limiting plate 19 and the second limiting plate 23 to move away from the aluminum profile, release the clamping mechanism to remove the aluminum profile, and then control the bending disc 16 and the telescopic arm 17 to reset.

The clamping mechanism includes a fixed plate 5 and a movable plate 6. The fixed plate 5 is fixedly arranged on the upper end of the third mounting plate 3. A second hydraulic cylinder 7 is arranged on the upper end of the third mounting plate 3 in the front-back direction. The second hydraulic cylinder 7 is connected to the movable plate 6.

[0027] The first sliding frame slides in the left-right direction, and the clamping mechanism is used to clamp the aluminum profile. A second sliding frame is slidably arranged on the side of the support platform 1 in the front-back direction. The second sliding frame includes a second slider 8 and a dovetail groove 9. A dovetail block is slidably arranged in the dovetail groove 9 and is fixedly connected to the second slider 8. A shifting mechanism is arranged between the support platform 1 and the second slider 8. The shifting mechanism controls the second slider 8 to slide in the front-back direction. After the second slider 8 moves to the target position, the shifting mechanism fixes the position of the second slider 8. The shifting mechanism includes a rack 10, which is fixedly arranged on the side of the second slider 8 in the front-back direction. A drive unit is arranged on the support platform 1. The drive unit is equipped with a gear 11 that meshes with the rack 10. The drive unit includes a self-locking worm gear reducer 12 and a drive motor 13 connected to it. The self-locking worm gear reducer ensures that the second slider 8 will not move under the action of external force.

[0028] The lower end of the second slider 8 is provided with a drive mechanism 14. The drive mechanism 14 is vertically provided with a drive shaft 15 extending above the second sliding frame. The upper end of the drive shaft 15 is detachably provided with a bending disc 16. The drive mechanism 14 drives the bending disc 16 to rotate through the drive shaft 15. The detachable bending disc 16 makes it easy to replace bending discs 16 of different diameters to adapt to bending requirements of different sizes.

[0029] A telescopic arm 17 is fixedly installed on the drive shaft 15 below the bending disc 16. A first mounting block 18 is connected to the end of the telescopic arm 17. A first limiting plate 19 is provided on the first mounting block 18. The telescopic arm 17 extends and retracts to adjust the distance between the first limiting plate 19 and the bending disc 16. The first limiting plate 19 and the bending disc 16 work together to clamp the aluminum profile.

[0030] A third sliding frame extending in the front-to-back direction is provided on the upper end of the support platform 1 between the first sliding frame and the limiting plate. The third sliding frame includes a second mounting block 20, which slides in the front-to-back direction. The third sliding frame includes two parallel second guide shafts 21, which extend in the front-to-back direction. The second mounting block 20 is slidably disposed between the two second guide shafts 21. A third hydraulic cylinder 22 parallel to the second guide shafts 21 is fixedly disposed on the upper end face of the support platform 1. The third hydraulic cylinder 22 is connected to the second mounting block 20. A second limiting plate 23 is slidably disposed on the rear side of the second mounting block 20 in the left-to-right direction. The second limiting plate 23 slides relative to the second mounting block 20 in the left-to-right direction. A return spring is provided between the second mounting block 20 and the second limiting plate 23. The return spring is used to reset the second limiting plate 23. The second limiting block is pressed against the side of the aluminum profile by moving the second mounting block 20. During the movement of the aluminum profile, the second limiting block moves with the aluminum profile.

[0031] The specific working process is as follows: When bending the aluminum profile, replace the bending disc 16 with one of the appropriate size according to the diameter of the rounded corner to be bent, adjust the length of the telescopic arm 17, and use the clamping mechanism to clamp the aluminum profile. Use the first limiting plate 19 and the bending disc 16 to clamp the end of the aluminum profile, and use the second limiting plate 23 to press the middle of the aluminum profile. Then, use the driving mechanism 14 to drive the bending disc 16 and the telescopic arm 17 to rotate synchronously. During the rotation, the first sliding frame drives the aluminum profile to move to the left, and the second limiting plate 23 moves synchronously with the aluminum profile. After bending is completed, control the first limiting plate 19 and the second limiting plate 23 to move away from the aluminum profile. Under the elastic force of the return spring, the second limiting plate 23 returns to its original position. Release the clamping mechanism to remove the aluminum profile, and then control the bending disc 16 and the telescopic arm 17 to return to their original positions.
