The first hydraulic cylinders 19 are fixedly mounted in the mounting holes at the bottom of a top plate. The top plate is fixedly mounted on the upper end of a mounting box 20. A mounting shaft 13 is provided below the upper mold 18. The mounting shaft 13 is rotatably mounted in a rotating hole inside the mounting box 20. A plurality of mounting brackets 12 are fixedly mounted at equal intervals on the mounting shaft 13. A lower mold 11 is fixedly mounted on each mounting bracket 12. The bottom end of each lower mold 11 is symmetrically provided with mounting grooves. A top block 21 is slidably mounted in each mounting groove. The bottom end of each top block 21 is aligned with the bottom end of the top block 21. The lower mold 11 is equipped with a guide slide rod 22, which is slidably disposed inside the lower mold 11. A circular plate is fixedly disposed at one end of the guide slide rod 22. A sliding groove is disposed inside the lower mold 11 at a position corresponding to the circular plate. A tension spring 23 is disposed at the upper end of the circular plate at a position corresponding to one end of the sliding groove. A correction mechanism is provided at the upper end of the mounting box 20 for correcting the position of the door and window profiles inside the lower mold 11. A feeding mechanism is provided on one side of the mounting box 20 for automatically feeding the door and window profiles. The correction mechanism facilitates the correction of the position of the door and window profiles to be processed inside the lower mold 11, and the feeding mechanism facilitates the automatic feeding of materials into the lower mold 11.

[0027] One end of the mounting shaft 13 extends to the outside of the mounting box 20. A worm gear 14 is fixedly mounted on one end of the mounting shaft 13. A worm 15 is meshed on the worm gear 14. A first rotating plate is rotatably mounted on the rotating shafts at both ends of the worm 15. The first rotating plates are fixedly mounted on one side of the mounting box 20. One end of the rotating shaft of the worm 15 is fixedly connected to the output end of the first motor 16. The first motor 16 is fixedly mounted on one side of the mounting box 20. In use, when it is necessary to process the door and window profiles, the first motor 16 is started. The output end of the first motor 16 drives the worm 15 to rotate. The worm 15 meshes with the worm gear 14 and drives the mounting shaft 13 to rotate. The mounting shaft 13 drives several lower molds 11 to rotate. When the lower mold 11 loaded with the door and window profiles to be processed rotates to directly below the upper mold 18 and stops, the first hydraulic cylinder 19 is started. The output end of the first hydraulic cylinder 19 drives the upper mold 18 to move. Through the cooperation of the upper mold 18 and the internal forming cavity of the lower mold 11, the door and window profiles are bent and formed.

[0028] The correction mechanism includes two symmetrically arranged spring telescopic rods 24, both positioned below the upper mold 18. A T-shaped slider is fixed to the bottom end of each spring telescopic rod 24, sliding within a T-shaped groove on the upper end of a fixing block 25. The fixing blocks 25 are fixed to the upper end of the mounting box 20. A crossbar is fixed to the output end of each spring telescopic rod 24. A rectangular through hole is provided on one side of the lower mold 11 corresponding to the position of the crossbar. A second fixing seat is fixed to the upper end of each spring telescopic rod 24, with a connecting rod 26 hinged to each second fixing seat. A first fixing seat 27 is hinged to the other end of each connecting rod 26, fixed to the bottom end of a sliding plate 28. A sliding hole is symmetrically provided on the upper end of the sliding plate 28, with a second guide rod sliding within each sliding hole. The second guide rods are fixed to the upper end of the mounting box 20. The bottom end of the sliding plate 28 is fixedly connected to one end of each of two return springs 29, with the other end of each return spring 29 fixed to the mounting box 20. At the two ends, pressing frames 30 are fixedly installed at positions corresponding to the output ends of the two first hydraulic cylinders 19 and the two sliding plates 28, respectively. In use, after the lower mold 11 rotates the door / window profile to be processed to below the upper mold 18, the output ends of the first hydraulic cylinders 19 move the upper mold 18 while simultaneously moving the pressing frames 30. During the movement of the pressing frames 30, after the pressing frames 30 are in close contact with the upper end of the sliding plates 28, the pressing frames 30 push the sliding plates 28 to move. The sliding plates 28 then slide via the connecting rod 26, causing the spring telescopic rod 24 to slide. When the output ends of the two spring telescopic rods 24 are tightly attached to both ends of the door and window profile, the two spring telescopic rods 24 can correct the position of the door and window profile. When the upper mold 18 presses and bends the door and window profile, the top block 21 slides into the mounting groove inside the lower mold 11. After the first hydraulic cylinder 19 drives the upper mold 18 back to the initial position, under the action of the reset spring 29, the sliding plate 28 drives the spring telescopic rods 24 back to the initial position through the connecting rod 26, so that the output ends of the spring telescopic rods 24 are disengaged from the lower mold 11.

[0029] The feeding mechanism includes a storage box 33, which is fixedly installed in the mounting groove at the upper end of the mounting box 20. One end of the storage box 33 is fitted with a receiving pipe, which is fixedly installed inside the mounting box 20. One end of the receiving pipe is fixedly fitted with a bearing plate 34, which is fixedly installed inside the mounting box 20. A limiting tube is provided on the outside of the mounting box 20 at a position corresponding to the bearing plate 34. A pushing frame 35 is slidably installed inside the limiting tube. Both ends of the pushing frame 35 are fixedly connected to the output ends of two second hydraulic cylinders 36, which are both fixedly installed inside the mounting box 20. In use, when the lower mold 11 without door and window profiles rotates to the position of the bearing pipe, the second hydraulic cylinders 36 are activated. The output ends of the second hydraulic cylinders 36 drive the pushing frame 35 to move. The pushing frame 35 pushes the door and window profiles on the upper end of the bearing plate 34 into the lower mold 11. Then, the output ends of the second hydraulic cylinders 36 drive the pushing frame 35 back to the initial position, thereby completing the feeding.

[0030] A conveyor belt 31 is installed inside the mounting box 20, positioned below the lower mold 11. A drive roller and a transmission roller are respectively installed at both ends of the conveyor belt 31. The rotating shafts at both ends of the drive roller and transmission roller are rotatably disposed within rotating holes at both ends of two retaining plates. The retaining plates are fixedly installed inside the mounting box 20. One rotating shaft of the drive roller is fixedly connected to the output end of a second motor 32. The second motor 32 is fixedly installed on one side of the mounting box 20. A baffle 17 is provided inside the mounting box 20 at a position corresponding to the rotation direction of the mounting shaft 13. The baffle 17 is... The baffle 17 is arranged in an arc shape, with its inner side tightly attached to one end of the lower mold 11. In use, after the door and window profiles are processed, the mounting shaft 13 drives the lower mold 11 to rotate. During the rotation of the lower mold 11, the upper end of the lower mold 11 is tightly attached to the inner side of the baffle 17, which prevents the door and window profiles inside the lower mold 11 from falling off. After the lower mold 11 rotates to be directly above the conveyor belt 31, the lower mold 11 disengages from the baffle 17, and then the door and window profiles fall onto the upper end of the conveyor belt 31. The output end of the second motor 32 drives the conveyor belt 31 to rotate, thereby transferring the door and window profiles to the outside of the mounting box 20.

[0031] Both retaining plates are fixedly provided with limiting plates at their upper ends. When in use, these plates can be used to limit the position of the door and window profiles after they have been bent and formed at the upper end of the conveyor belt 31, thereby preventing the door and window profiles from falling off and detaching from the upper end of the conveyor belt 31.

[0032] The above embodiment discloses a door and window profile bending and forming device. The lower mold 11 rotates the door and window profile to be processed to below the upper mold 18. Simultaneously, the output end of the first hydraulic cylinder 19 moves the upper mold 18 and the pressing frame 30. During the movement of the pressing frame 30, it comes into close contact with the upper end of the sliding plate 28, pushing the sliding plate 28 to move. The sliding plate 28 drives the spring telescopic rod 24 to slide via the connecting rod 26. When the output ends of the two spring telescopic rods 24 are respectively in close contact with both ends of the door and window profile, the two spring telescopic rods 24 can correct the position of the door and window profile. When the upper mold 18 presses and bends the door and window profile, the top block 21 slides into the mounting groove inside the lower mold 11. After the first hydraulic cylinder 19 drives the upper mold 18 back to its initial position, under the action of the return spring 29, the sliding plate 28 drives the spring telescopic rod 24 back to its initial position via the connecting rod 26, causing the output end of the spring telescopic rod 24 to disengage from the lower mold 11. The mounting shaft 13 then... The lower mold 11 rotates, and during the rotation, the upper end of the lower mold 11 is in close contact with the inner side of the baffle 17 to prevent the door and window profiles inside the lower mold 11 from falling off. After the lower mold 11 rotates to be directly above the conveyor belt 31, the lower mold 11 detaches from the baffle 17, and then the door and window profiles fall onto the upper end of the conveyor belt 31. The output end of the second motor 32 drives the conveyor belt 31 to rotate, thereby transferring the door and window profiles to the outside of the mounting box 20. At the same time, the lower mold 11 without door and window profiles rotates to the position of the bearing tube, and the second hydraulic cylinder 36 is activated. The output end of the second hydraulic cylinder 36 drives the pusher 35 to move. The pusher 35 pushes the door and window profiles on the upper end of the bearing plate 34 to move into the lower mold 11. Then the output end of the second hydraulic cylinder 36 drives the pusher 35 back to the initial position, thereby completing the loading. In addition, several electrical components in this application use existing components, and the specific structure and control principle are common knowledge. The control methods of several electrical components are set according to actual use, and will not be described in detail here.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
