[0024] The fixing plate 8 is configured to be an arc-shaped structure.

[0025] like Figure 3 As shown, the rotating device 2 includes a third mounting frame 19 and a rotating frame 22, two cylinders 20 are arranged side by side in the third mounting frame 19, the front end of the cylinder 20 is connected to the bottom of the rotating frame 22, a rotating shaft 46 is arranged at the bottom center of the rotating frame 22 and is installed on the third mounting frame 19 through the rotating shaft 46, a plurality of guide rods 21 are arranged between the rotating frame 22 and the third mounting frame 19, a moving wheel 13 is arranged at the bottom of the third mounting frame 19, and the moving wheel 13 is installed on the slide rail 4.

[0026] like Figure 7As shown, a first screw rod 36 is provided through the lower ends of the first clamping device 1, the rotating device 2 and the second clamping device 3, a shaft sleeve is provided at the rear end of the first screw rod 36 and connected to the second mounting frame 11 through the shaft sleeve, a rotating tooth is provided at the front end of the first screw rod 36, a second hand wheel 38 is provided on one side of the first screw rod 36, a rotating tooth is provided at the front end of the second hand wheel 38, the rotating teeth of the second hand wheel 38 are meshed with the rotating teeth of the first screw rod 36, and a connecting shaft 37 is provided near the front end of the first screw rod 36.

[0027] The adjusting rod 9 and the adjusting support rod 7 as well as the adjusting support rod 7 and the fixing plate 8 are both provided with rotation nodes and are connected via the rotation nodes.

[0028] A slide groove is provided on the second mounting frame 11 , and a slider is provided at the bottom of the limiting wheel 5 , and the slider is installed in the slide groove.

[0029] The height of the rotating device 2 is lower than that of the first clamping device 1 and the second clamping device 3 .

[0030] During use, the second hand wheel 38 is rotated according to the length of the spiral tube to be flanged, driving the first screw rod 36 to rotate, so that the first clamping device 1 and the rotating device 2 are moved forward and backward on the slide rail 4. After the adjustment is completed, the spiral tube to be flanged is placed on the first clamping device 1 and the second clamping device 3, and then the first hand wheel 12 is rotated to rotate the screw rod 10. Since the screw rod 10 is provided with a reverse thread, during the rotation of the screw rod 10, the nut sleeve at one end of the adjusting rod 9 will move toward the center direction of the screw rod 10, further driving the adjusting rod 9 to rotate to the left, further driving the adjusting support rod 7 to rotate to the right, and further driving the fixing plate 8 and the upper guide roller 17 rotate to the right, thereby clamping and fixing the spiral tube. After the spiral tube is clamped, the third cylinder 26 pushes the movable plate 29 forward to move until the outer periphery of one end of the spiral tube passes between the upper pressing wheel 24 and the lower pressing wheel 31 and is below the flanging wheel 30, then the movable plate 29 stops moving forward, and then the first oil cylinder 25 pushes the rotating shaft 33 downward, so that the upper pressing wheel 24 is pressed on the inner wall surface of the outer periphery of one end of the spiral tube, and then the third oil cylinder 39 pushes the rack 41 forward, thereby driving the gear 42 to rotate, further driving the flip cross bar 23 to rotate, further causing the vertical flanging wheel 30 to tilt and the spiral The outer periphery of one end of the tube is flanged outward by 90 degrees. At the same time, the driving motor 28 drives the lower transmission chain 34 to rotate, further drives the upper transmission chain 35 to rotate, further drives the universal coupling 27 to rotate, thereby driving the upper pressing wheel 24 to rotate, so that the spiral tube is flanged and rotated at the same time. After the outer periphery of one end of the spiral tube is completely flanged, the third oil cylinder 39 pulls the rack 41 backward, thereby driving the gear 42 to rotate, further driving the flip cross bar 23 to reset, and further resetting the flanging wheel 30 to a vertical state. After that, the first oil cylinder 25 pulls the rotating shaft 33 upward, so that the upper pressing wheel 24 is separated from the inner wall surface of the outer periphery of one end of the spiral tube, and then The movable plate 29 is pulled backward by the second oil cylinder 26 to move backward, so that the outer periphery of one end of the spiral tube is away from the flanging wheel 30, the upper pressing wheel 24 and the lower pressing wheel 31, and then the first hand wheel 12 is turned to disengage the clamping claws to release the clamping state of the spiral tube. After the spiral tube is released from the clamping state, the rotating frame 22 is lifted upward by the first cylinder 20 so that the rotating frame 22 lifts the spiral tube and disengages the spiral tube from the first clamping device 1 and the second clamping device 3. Then the spiral tube is manually pushed so that the spiral tube and the rotating frame 22 rotate with the rotating shaft 46 as the rotation point, so that the other end of the spiral tube is rotated to the front end for flanging the other end, thereby completing the flanging of the outer periphery of the spiral tube.

[0031] If the upper and lower heights of the first clamping device 1 need to be adjusted, the second mounting frame 11 can be lifted upward or lowered downward by rotating the adjusting bolt 14 , thereby achieving height adjustment of the first clamping device 1 .

[0032] like Fig. 9 As shown, the flange 49 is in contact with the flange 48 of the spiral tube 47 and is fixed by bolts.

[0033] The beneficial effects of the utility model are as follows: the utility model has reasonable structural design and is easy to use. Mechanical flanging is achieved by cooperating between the pressing wheel and the flanging wheel, thereby improving the quality and efficiency of the flanging of the spiral tube. The utility model can also be adjusted according to the length and size of the spiral tube, and has good flexibility in use.
