Simultaneously, through the cooperation of a rack and pinion box, a first rack, a second rack, a first gear, and a second gear, the first rotating rod and the first rotating cylinder can be driven to rotate in opposite directions, thereby causing the first and second telescopic rods to rotate and apply pressure to the curtain rod, thus bending it. This reduces the damage caused by additional concentrated stress on the fixed area during the bending process after the curtain rod is clamped and fixed, enhancing the stability of the bending machine.

Detailed Implementation
[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] refer to Figures 1-6 A high-efficiency curtain rod bending machine includes a workbench 10, on which a positioning top plate 14 is fixedly connected. The positioning top plate 14 has several vertical sliding grooves 20 arranged circumferentially with the center of the positioning top plate 14 as the center. Each of the vertical sliding grooves 20 has a clamping block base 19 slidably connected. Each of the clamping block bases 19 has a threaded positioning rod 18 fixedly connected to its top. Each of the threaded positioning rods 18 has a clamping block connecting rod 17 threadedly connected to its top. An upper clamping block 15 is fixedly connected to the end of the clamping block connecting rod 17 away from the threaded positioning rod 18. A lower clamping block 16 is fixedly connected to the end of each clamping block base 19 near the upper clamping block 15. The lower clamping block 16 is located directly below the upper clamping block 15.
[0027] By rotating the threaded positioning rod 18, the height of the upper clamping block 15 can be adjusted to accommodate the clamping and positioning of curtains of different sizes.
[0028] like Figures 1-6As shown, a clamping block positioning box 35 is fixedly connected to the bottom of the positioning top plate 14. A positioning rotating plate 36 is rotatably connected to the bottom of the clamping block positioning box 35. A worm gear connecting rod 21 is fixedly connected to the center of the positioning rotating plate 36. A worm gear 22 is fixedly connected to the end of the worm gear connecting rod 21 away from the positioning rotating plate 36. A worm connecting rod 25 is fixedly connected to the bottom of the worktable 10. A worm 24 is rotatably connected to the end of the worm connecting rod 25 away from the worktable 10. A rotating handle 23 is fixedly connected to the end of the worm 24 away from the worm connecting rod 25. The worm 24 and the worm gear 22 are meshed together.
[0029] By rotating the worm 24, the worm wheel 22 is driven to rotate, thereby causing the positioning rotating plate 36 to rotate. At the same time, since the worm wheel 22 cannot rotate when the worm 24 stops rotating, the positioning rotating plate 36 can be locked after rotating a certain angle, which is beneficial to the positioning of the positioning rotating plate 36.
[0030] like Figures 1-6 As shown, the positioning rotating plate 36 has several arc-shaped sliding grooves 38 arranged in a circle with the center of the positioning rotating plate 36 as the center. The bottom of the clamping block base 19 is fixed with a positioning sliding rod 37, which is slidably connected to the vertical sliding groove 20 and the arc-shaped sliding groove 38.
[0031] Through the cooperation of the worm gear connecting rod 21, worm gear 22 and worm 24, the positioning rotating plate 36 can be driven to rotate, and the positioning slide rod 37 can slide in the vertical slide groove 20 and the arc-shaped slide groove 38, thereby driving the upper clamping block 15 and the lower clamping block 16 installed on the clamping block base 19 to move, so that the bending machine can adapt to the bending of curtain rods with different curvatures and improve the applicability of the bending machine.
[0032] like Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, a first rotating rod 11 is rotatably connected to the workbench 10, a first telescopic rod 12 is fixedly connected to the first rotating rod 11, a first rotating cylinder 28 is sleeved on the outer side of the first rotating rod 11, the first rotating cylinder 28 is rotatably connected to the workbench 10, a second telescopic rod 27 is fixedly connected to the first rotating cylinder 28, a bending block 13 is fixedly connected to the end of the first telescopic rod 12 and the second telescopic rod 27 away from the first rotating rod 11, a positioning frame 26 is fixedly provided at the bottom of the workbench 10, a rack box 29 is slidably connected in the positioning frame 26, a first rack 30 is fixedly provided at the bottom of one side wall of the rack box 29, and a second rack 31 is fixedly provided at the top of the other side wall of the rack box 29.
[0033] By adjusting the lengths of the first telescopic rod 12 and the second telescopic rod 27, the bending block 13 can be moved to the area where the curtain rod needs to be bent, thus improving the applicability of the bending machine to different bending arcs of the curtain rod.
[0034] like Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, a first gear 32 is fixed at one end of the first rotating rod 11 near the rack box 29, and a second gear 33 is fixed at one end of the first rotating cylinder 28 near the rack box 29. The second gear 33 is located directly above the first gear 32. The first gear 32 and the second gear 33 are meshed and connected with the first rack 30 and the second rack 31, respectively. A rack box push rod 34 is fixed at one end of the rack box 29. The first rotating rod 11 and the first rotating cylinder 28 rotate as the rack box 29 slides.
[0035] Through the cooperation of the rack box 29, the first rack 30, the second rack 31, the first gear 32 and the second gear 33, the first rotating rod 11 and the first rotating cylinder 28 can be driven to rotate in opposite directions, thereby driving the first telescopic rod 12 and the second telescopic rod 27 to rotate and apply pressure to the curtain rod, thus bending the curtain rod. This reduces the damage caused by the additional concentrated stress on the fixed area when the curtain rod is clamped and fixed and then bent, and enhances the stability of the bending machine.
[0036] In this embodiment, initially, the operator places the curtain rod on the lower clamping block 16 near the bending block 13. Then, the operator rotates the threaded positioning rod 18, causing the upper clamping block 15 on the clamping block connecting rod 17 to descend and abut against the curtain rod. Subsequently, the operator rotates the remaining threaded positioning rods 18 in sequence to keep the remaining upper clamping blocks 15 at the same height.
[0037] After the operator determines the required bending arc of the curtain rod, they rotate the handle 23, causing the worm gear 24 to rotate as well. The worm wheel 22, which is meshed with the worm gear 24, begins to rotate, causing the worm wheel connecting rod 21 to rotate as well. The positioning rotating plate 36 rotates along with the worm wheel connecting rod 21, and the positioning slide rod 37 slides on the vertical slide groove 20 and the arc-shaped slide groove 38, causing the clamping block base 19 to slide away from the worm wheel connecting rod 21.
[0038] After the clamping base 19 slides outward to meet the bending radius requirement of the curtain rod, the operator then extends the first telescopic rod 12 and the second telescopic rod 27 to the position where the curtain rod needs to be bent. The operator then pushes the rack box push rod 34, and the first gear 32 and the second gear 33 rotate in opposite directions as the rack box push rod 34 slides. The first rotating rod 11 and the first rotating cylinder 28 rotate together, causing the first telescopic rod 12 and the second telescopic rod 27 to rotate towards one side of the curtain rod. The two bending blocks 13 begin to squeeze the two sides of the curtain rod and gradually bend it. When the curtain rod abuts between the lateral upper clamping block 15 and the lower clamping block 16, the operator stops pushing the rack box push rod 34 and rotates the threaded positioning rod 18 in the opposite direction to remove the curtain rod from the bending machine, completing the bending of the curtain rod.
[0039] The first telescopic rod 12, worm gear 22, worm 24 and the second telescopic rod 27 mentioned above are mature existing technologies and will not be described in detail here.
