[0023] Reference Figs. 1-4In this embodiment of the present invention, a metal door and window processing bending device includes a processing table 1, a connecting rod 2 fixedly connected to the bottom of the processing table 1, a support seat 3 fixedly connected to the connecting rod 2, a rotating shaft 4 rotatably connected to the bottom of the processing table 1, a rotating seat 5 fixedly connected to the rotating shaft 4, an arc-shaped frame 6 fixedly connected to the outer wall of the processing table 1, an arc-shaped groove 7 provided between the arc-shaped frame 6 and the processing table 1, a slider 9 slidably connected in the arc-shaped groove 7, a first rotating frame 10 fixedly connected to the rotating seat 5, the first rotating frame 10 being fixedly connected to the slider 9, a rotating rod 11 fixedly connected to the top of the slider 9, a rotating clamp 12 fixedly connected to one side of the rotating rod 11, a second rotating frame 15 fixedly connected to the rotating seat 5, the first rotating frame 10 and the second rotating frame 15 being arranged perpendicular to each other, a first clamp 19 being provided on the second rotating frame 15, the first clamp 19 cooperating with the rotating clamp 12;

[0024] A fixed rod 24 is fixedly connected to the center of the processing table 1. The axis of the fixed rod 24 coincides with the axis of the rotating shaft 4. A flexible bending sleeve 25 is fixedly connected to the top of the fixed rod 24. A rotating block 26 is rotatably connected to the bottom of the fixed rod 24. A rotating arm 27 is fixedly connected to the rotating block 26. An angle pointer 30 is fixedly connected to the rotating arm 27. The angle pointer 30 cooperates with the angle ruler 8. A pointer slot 13 is provided in the rotating rod 11. The pointer slot 13 cooperates with the angle pointer 30. A limit groove 29 is fixedly connected to the rotating clamp 12. A limit block 28 is fixedly connected to the rotating arm 27. The limit block 28 cooperates with the limit groove 29.

[0025] A handle 14 is fixedly connected to the side of the rotating rod 11 away from the rotating clamping plate 12, and a handle 31 is fixedly connected to the rotating arm 27; a limit clamping assembly is installed between the arc frame 6 and the rotating arm 27; a telescopic drive assembly is installed between the second rotating frame 15 and the first clamping plate 19; a fixed clamping assembly is provided on the side of the processing table 1 away from the second rotating frame 15.

[0026] This invention begins by gripping the handle 14 and rotating the rotating rod 11, thereby making the rotating clamping plate 12 parallel to the fixed clamping assembly. At this time, the rotating rod 11 rotates to the zero point of the angle ruler 8. The fixed end of the workpiece can then be placed into the fixed clamping assembly, and the rotating end placed between the first clamping plate 19 and the rotating clamping plate 12. At the same time, the bending point of the workpiece is engaged with the fixed rod 24. Then, the first clamping plate 19 is driven to slide through the telescopic drive assembly, thereby fixing and clamping the rotating end of the workpiece through the cooperation of the first clamping plate 19 and the rotating clamping plate 12. The fixed end of the workpiece is also fixed and clamped by the fixed clamping assembly. Next, the handle 31 is gripped and the rotating arm 27 is rotated, thereby adjusting the angle of the rotating arm 27 according to the angle required for bending the workpiece. At the same time, the relative angle of the rotating arm 27 is accurately adjusted through the cooperation of the angle pointer 30 and the angle ruler 8. After adjustment, the rotating arm 27 and the arc frame 6 are clamped and fixed by the limiting clamping assembly.

[0027] Then, grasp the handle 14 and drive the rotating rod 11 to rotate. The rotating rod 11 drives the first rotating frame 10 to rotate. The first rotating frame 10 drives the second rotating frame 15 to rotate through the rotating seat 5. The first rotating frame 10 drives the rotating clamp 12, and the second rotating frame 15 drives the first clamp 19, thereby realizing the synchronous rotation of the rotating clamp 12 and the rotating clamp 19. At this time, the rotating end of the workpiece rotates towards the rotating arm 27. At this time, the bending point of the workpiece rotates and bends under the action of the fixed rod 24. During the bending process, the flexible bending sleeve 25 prevents the workpiece from wearing during the bending process. At the same time, during the bending process, the rotation angle of the rotating rod 11 is limited by the cooperation of the limiting block 28 and the limiting groove 29, thereby accurately positioning the bending angle of the workpiece, thus realizing the bending processing of the workpiece.

[0028] In one instance of this embodiment, please refer to Figs. 1-4 The limiting clamping assembly includes a second threaded cylinder 32 fixedly connected to the bottom of the rotating arm 27. A second screw 33 is internally threaded to the second threaded cylinder 32. A clamping pin 35 is fixedly connected to one end of the second screw 33. The clamping pin 35 cooperates with the arc frame 6. A second knob 34 is fixedly connected to the driving end of the second screw 33.

[0029] The limiting clamping assembly can drive the second screw 33 to rotate by turning the second knob 34. The second screw 33 is connected to the second threaded cylinder 32 by thread, which converts the rotational motion of the second screw 33 into linear motion, thereby driving the clamping pin 35 to extend. Then, the clamping pin 35 and the arc frame 6 are fastened and fixed by their mutual cooperation, thereby limiting and fixing the rotating arm 27 and the arc frame 6.

[0030] In one instance of this embodiment, please refer to Figs. 1-4 The telescopic drive assembly includes a mounting frame 16 fixedly connected to the second rotating frame 15, a first fixed cylinder 17 fixedly connected inside the mounting frame 16, a first sliding rod 18 slidably connected inside the first fixed cylinder 17, a first clamping plate 19 fixedly connected to one end of the first sliding rod 18, a first drive frame 20 fixedly connected to the other end of the first sliding rod 18, a first threaded cylinder 21 fixedly connected inside the mounting frame 16, a first screw 22 threadedly connected inside the first threaded cylinder 21, the first screw 22 rotatably connected to the first drive frame 20, and a first knob 23 fixedly connected to the drive end of the first screw 22.

[0031] The telescopic drive assembly places the workpiece between the rotating clamping plate 12 and the first clamping plate 19, and then turns the first knob 23. The first knob 23 drives the first screw 22 to rotate. The first screw 22 is connected to the first threaded cylinder 21 by a thread, which converts the rotational motion of the first screw 22 into linear motion acting on the first drive frame 20. The first drive frame 20 drives the first clamping plate 19 to slide and extend through the first sliding rod 18, thereby adjusting the relative position between the first clamping plate 19 and the rotating clamping plate 12. Thus, the first clamping plate 19 and the rotating clamping plate 12 cooperate to fix and hold one end of the workpiece.

[0032] In one instance of this embodiment, please refer to Figs. 1-4 The fixed clamping assembly includes a fixed clamping plate 36 fixedly connected to the processing table 1, a second clamping plate 40 provided on one side of the fixed clamping plate 36, the second clamping plate 40 cooperating with the fixed clamping plate 36, a fixed frame 37 fixedly connected to the processing table 1, a second fixed cylinder 38 fixedly connected inside the fixed frame 37, a second sliding rod 39 slidably connected inside the second fixed cylinder 38, the second clamping plate 40 fixedly connected to one end of the second sliding rod 39, a second drive frame 41 fixedly connected to the other end of the second sliding rod 39, a third threaded cylinder 42 fixedly connected inside the fixed frame 37, a third screw 43 threadedly connected inside the third threaded cylinder 42, the third screw 43 rotatably connected to the second drive frame 41, and a third knob 44 fixedly connected to the drive end of the third screw 43;

[0033] The fixed clamping assembly first places the workpiece between the fixed clamping plate 36 and the second clamping plate 40, and then turns the third knob 44. The third knob 44 drives the third screw 43 to rotate. The third screw 43 is connected to the third threaded cylinder 42 by a thread, which converts the rotational motion of the third screw 43 into linear motion acting on the second drive frame 41. The second drive frame 41 drives the second clamping plate 40 to slide and extend through the second sliding rod 39, thereby adjusting the relative position between the second clamping plate 40 and the fixed clamping plate 36. Thus, the other end of the workpiece is fixedly clamped and fixed by the cooperation between the second clamping plate 40 and the fixed clamping plate 36.
