[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Combination Figures 1-4 A double-headed pipe bending machine includes a base 1, and a picking and placing mechanism 2, a bending mechanism 3 and a positioning mechanism 4 are installed on the top of the base 1.

[0019] See Figure 2 and Figure 3 Furthermore, the picking and placing mechanism 2 includes a fixed frame 5, a first cylinder 6, and a second cylinder 7. The fixed frame 5 is fixedly installed on the top of the base 1, and the first cylinder 6 is fixedly installed on the top of the fixed frame 5. A positioning plate 8 is fixedly installed at the front end of the telescopic rod of the first cylinder 6. The second cylinder 7 is movably installed on the top of the fixed frame 5. The top end of the telescopic rod of the second cylinder 7 and the top of the fixed frame 5 are movably installed with the same support rod 9. A pressure plate 10 is fixedly installed at the front end of the support rod 9. The bending mechanism 3 includes a bidirectional threaded rod 11 and two sliding rods 12. The base 1 has two housings 13, a bidirectional threaded rod 11 is movably mounted on the top of the base 1, two slide rods 12 are fixedly mounted on the top of the base 1, the two housings 13 are movably mounted outside the bidirectional threaded rod 11 and the two slide rods 12, a rotating roller 14 is movably mounted on the top of the housing 13, a guide frame 15 is fixedly mounted outside the rotating roller 14, an adjusting rod 16 is movably connected through the front of the guide frame 15, a slide 17 is movably mounted at the rear end of the adjusting rod 16 and inside the guide frame 15, and a pressure roller 18 is movably mounted inside the slide 17.

[0020] The bottom end of the second cylinder 7 and the top end of the telescopic rod are connected to the fixed frame 5 and the support rod 9 respectively by hinges. The support rod 9 is also connected to the fixed frame 5 by hinges. The second cylinder 7 drives the support rod 9 to rotate, so that the pressure plate 10 is separated from the positioning plate 8, so as to facilitate the picking, placing and positioning of the tube.

[0021] The threads at both ends of the bidirectional threaded rod 11 are arranged in opposite directions. The housing 13 and the bidirectional threaded rod 11 are connected by threads. The bidirectional threaded rod 11 drives the two housings 13 to slide, thereby adjusting the position of the tube bending.

[0022] The adjusting rod 16 is threaded through the front of the guide frame 15, and the slide 17 is located inside the guide frame 15 and is slidably disposed. The adjusting rod 16 and the slide 17 are connected by a bearing. The adjusting rod 16 drives the slide 17 to slide, which is used to adjust the distance between the pressure roller 18 and the rotating roller 14. It is suitable for tubes of different diameters.

[0023] Specifically, the two housings 13 slide through the bidirectional threaded rod 11 to adjust the bending position at both ends of the tube. The support rod 9 drives the pressure plate 10 to press and fix the tube. The rotating roller 14 and the guide frame 15 drive the pressure roller 18 to rotate so that both ends of the tube can be bent at the same time. The sliding frame 17 is driven to slide through the adjusting rod 16 to adjust the distance between the pressure roller 18 and the rotating roller 14.

[0024] Example 2 See Figure 4 Furthermore, based on Embodiment 1, the positioning mechanism 4 includes a guide rail 19, a screw 20, and a guide block 23. The guide rail 19 is fixedly installed on the top of the base 1 near the front end. The screw 20 is movably installed inside the guide rail 19. A rocker plate 21 is installed at one end of the screw 20. A scale plate 22 is installed at the front of the guide rail 19. The guide block 23 is movably connected to the outside of the screw 20. A fixing post 24 is fixedly installed on the top of the guide block 23. A baffle 25 is fixedly installed at the rear of the fixing post 24.

[0025] The screw 20 is located inside the guide rail 19 and is rotatably arranged. The guide block 23 is threadedly connected to the screw 20. The screw 20 drives the guide block 23 to slide, thereby adjusting the position of the baffle 25.

[0026] The guide block 23 extends inward from the bottom of the fixed column 24. The baffle 25 and the bend of the two rotating rollers 14 are on the same axis. The guide block 23 is used to extend the distance of sliding outward. The baffle 25 positions one end of the tube.

[0027] Specifically, the screw 20 drives the guide block 23 to slide, and one end of the tube contacts the baffle 25, which facilitates the quick positioning of the tube and makes the bending positions of both ends of the tube the same. The guide block 23 slides outward to extend the positioning position of the tube.

[0028] In actual operation, the two tubes are placed between the two guide frames 15, and the two ends of the tubes are bent simultaneously by the two pressure rollers 18. The baffle 25 positions one end of the tube so that the tube is centered. During bending and handling, the bidirectional threaded rod 11 is driven to rotate by a motor, and the two housings 13 slide through the bidirectional threaded rod 11 to adjust the bending position of both ends of the tube body. The tube body is then inserted between the two guide frames 15. The second cylinder 7 extends and drives the support rod 9 to rotate, so that the pressure plate 10 presses the tube body against the front of the positioning plate 8 for fixation. The motors in the two housings 13 simultaneously drive the two rotating rollers 14 to rotate, so that the guide frame 15 drives the pressure roller 18 to rotate, bending both ends of the tube body simultaneously. After bending, the second cylinder 7 drives the support rod 9 to rotate, so that the pressure plate 10 is disengaged. The telescopic rod of the first cylinder 6 drives the positioning plate 8 to slide forward, pushing the tube body out for easy handling. The sliding frame 17 is slid by rotating the adjusting rod 16 to adjust the distance between the pressure roller 18 and the rotating roller 14. During positioning, by shaking the rocker 21, the screw 20 drives the guide block 23 to slide through the thread. The guide block 23 is slid to half the length of the tube by the scale plate 22, and one end of the tube contacts the baffle 25, so that the tube is in the center position, and the bending positions of both ends of the tube are the same. The guide block 23 slides outward to extend the positioning position of the tube.

[0029] By setting up the pick-and-place mechanism 2 and the bending mechanism 3, the first cylinder 6 drives the positioning plate 8 to slide, which facilitates the picking and fixing of the tube. The two machine boxes 13 are driven to slide by the bidirectional threaded rod 11 to adjust the bending position of the two ends of the tube. The slide 17 is driven to slide by the adjusting rod 16, which changes the distance between the pressure roller 18 and the rotating roller 14, which is suitable for bending tubes of different diameters. By setting up the positioning mechanism 4, the screw 20 drives the guide block 23 to slide, and one end of the tube contacts the baffle 25. The scale plate 22 facilitates the centering of the tube, so that the bending positions of the two ends of the tube are the same, which can position tubes of different lengths.

The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field.
