DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5, A bending machine for the production of aluminum alloy doors and windows, comprising a base 1. The top of the base 1 is fixedly connected to the bottom of a fixing plate 2 through a support rod. The top of the fixing plate 2 is rotatably connected to the bottom of a connecting plate 3 through a rotating rod. One end of the outer surface of the middle part of the connecting plate 3 is fixedly connected to one end of a first limiting rod 11. The other end of the first limiting rod 11 is fixedly connected to one end of the inner wall of the middle part of a rotating plate 12. The outer surface of the middle part of the first limiting rod 11 is slidably connected to the inner wall of one end of a positioning rod 10. One end cross-section of the first limiting rod 11 is arranged in a quadrilateral shape. By sliding the inner wall of one end of the positioning rod 10 on the outer surface of the middle part of the first limiting rod 11, the trajectory of the positioning rod 10 during movement can be fixed, improving the stability of the positioning rod 10 during movement. The top of the connecting plate 3 is fixedly connected to one end of a threaded rod 4. The outer surface of the middle part of the threaded rod 4 is threadedly connected to the inner wall of the middle part of a first rotating ring 5. One end cross-section of the first rotating ring 5 is arranged in a concave shape. The upper and lower surfaces of the inner wall of the middle part of the first rotating ring 5 are respectively slidably connected to the upper and lower surfaces of a first positioning plate 6. Due to the concave shape of one end cross-section of the first rotating ring 5, the first rotating ring 5 can smoothly drive the first positioning plate 6 to move up and down during rotation, and the angle of the first positioning plate 6 is not affected. When the first rotating ring 5 rotates to drive the first positioning plate 6 to move downward, the outer surface of the middle part of a sliding rod 8 can slide inside the inner wall of the middle part of a sliding frame 9, causing the sliding frame 9 to drive the positioning rod 10 to move towards the inner wall of the mold to fix the mold. One side of the inner wall of the middle part of the first rotating ring 5 is rotatably connected to the inner wall of the middle part of the first positioning plate 6. One side of the first positioning plate 6 is fixedly connected to one end of a push rod 7. One side of the outer surface of one end of the push rod 7 is slidably connected to one side of the inner wall of one side of the sliding frame 9. The sliding frame 9 is inclined. By sliding one side of the outer surface of one end of the push rod 7 on one side of the inner wall of one side of the sliding frame 9, the angle of the push rod 7 during movement can be fixed, improving the stability of the push rod 7 during movement. The inclined setting of the sliding frame 9 enables the push rod 7 to drive the sliding rod 8 to move downward and drive the sliding frame 9 to move, so that the sliding frame 9 can push the positioning rod 10 to move. The other end of the push rod 7 is fixedly connected to one side of the outer surface of the middle part of the sliding rod 8. The outer surface of the middle part of the sliding rod 8 is slidably connected to the inner wall of the middle part of the sliding frame 9. One side of the sliding frame 9 is fixedly connected to one side of the middle part of the positioning rod 10 through a fixing block. The number of positioning rods 10 is four. One side of the middle parts of the four positioning rods 10 is respectively fixedly connected to one side of the four sliding frames 9 through four fixing blocks. By respectively pushing the four positioning rods 10 to move by the four sliding frames 9, the four positioning rods 10 cooperate with each other to fix the mold and perform a centering operation on the mold at the same time.

[0028] One end of the threaded rod 4 is threadedly connected to the inner wall of the middle part of the second rotating ring 14. One end of the cross-section of the second rotating ring 14 is arranged in a concave shape. The upper and lower surfaces of the outer surface inner wall of the middle part of the second rotating ring 14 are respectively slidably connected to the upper and lower surfaces of the second positioning plate 15. The concave shape of one end of the cross-section of the second rotating ring 14 enables the second rotating ring 14 to smoothly drive the second positioning plate 15 to move up and down when rotating, and avoids affecting the angle of the second positioning plate 15. One side inner wall of the middle part of the second rotating ring 14 is rotatably connected to the inner wall of the middle part of the second positioning plate 15. One side of the second positioning plate 15 is fixedly connected to one end of the pressure rod 16. The inner wall of the middle part of the pressure rod 16 is slidably connected to the outer surface of the middle part of the second limiting rod 17. One end of the second limiting rod 17 is fixedly connected to the top of the rotating plate 12. By sliding the inner wall of the middle part of the pressure rod 16 on the outer surface of the middle part of the second limiting rod 17, the angle of the pressure rod 16 during movement can be fixed, and at the same time, the angle of the second positioning plate 15 during movement can be fixed.

[0029] One side of the fixed plate 2 is fixedly connected to the bottom of the operating table 13 through a fixing frame.

[0030] All the electrical components mentioned in this article are connected to the external main controller and 220V mains electricity, and the main controller can be a conventional known device such as a computer for control.

[0031] During use, when it is necessary to install the bending die, rotate the nut on the top of the second rotating ring 14 to drive the second rotating ring 14 to move upward, remove the second positioning plate 15 and the pressure rod 16 from the bending machine. The annular bending die is sleeved outside the four positioning rods 10. Rotate the nut on the top of the first rotating ring 5 to make the first rotating ring 5 rotate. When the first rotating ring 5 rotates, it moves downward through the threaded rod 4, driving the first positioning plate 6 to move downward, so that the push rod 7 drives the sliding rod 8 to move downward. The outer surface of the middle part of the sliding rod 8 slides inside the inner wall of the middle part of the sliding frame 9. Due to the inclined setting of the sliding frame 9, the sliding rod 8 can drive the sliding frame 9 to move. The sliding frame 9 starts to drive the positioning rods 10 to move towards the inner wall of the annular bending die until the four positioning rods 10 cooperate with each other to fix the inner wall of the annular bending die. Screw the inner wall of the middle part of the second rotating ring 14 onto the outer surface of one end of the threaded rod 4, and align the inner wall of the middle part of the pressure rod 6 with the second limiting rod 17, so that the inner wall of the middle part of the pressure rod 6 is sleeved on the outer surface of one end of the second limiting rod 17. Continuously rotate the nut on the top of the second rotating ring 14, so that the second rotating ring 14 starts to move downward through the threaded rod 4, driving the pressure rod 16 to move downward, so that the pressure rod 16 presses on the upper part of the annular bending die to press and fix the annular bending die.
