[0030] [[ID=~3]]Refer to [[ID=~4]] Figure 1 [[ID=~5]]and [[ID=~6]]<~ Figure 4 [[ID=~7]]As shown in the figure, as the first embodiment of the present invention, when the inner hole of the aluminum tube 31 to be processed bulges outwards (the aluminum tube 31 to be processed can be a straight tube or a bent tube), the power device includes a driving device and an auxiliary device. A connecting rod 16 is connected to the upper end of the driving device. The upper end of the connecting rod 16 is connected to an inner support component. The inner support component includes a positioning disk 17. The positioning disk 17 can be installed at the end of the connecting rod 16. Two vertical plates 18 are vertically connected to the lower surface of the positioning disk 17. A third threaded through hole is provided on each vertical plate 18. A screw rod 19 passes through each third threaded through hole. The inner end of the screw rod 19 is connected to an operation disk 20.

[0031] The external support assembly includes two sets of track openings 22 on the straight cylinder 1201. Both track openings 22 extend along the length of the straight cylinder 1201. Each track opening 22 has a third sliding groove on its two side walls extending along the length. An outer clamping block 23 is fitted inside the track opening 22. The side of the outer clamping block 23 is located in the third sliding groove. At this time, the outer clamping block 23 can slide inside the track opening 22. The outer clamping block 23 can move to the extension line of the inner clamping block. A fourth threaded through hole is provided on the outer clamping block 23. The fourth threaded through hole passes through the radial direction of the positioning cylinder 12. A locking rod 24 passes through the fourth threaded through hole. The locking rod 24 passes through the track opening 22. After the locking rod 24 is tightened, the inner end of the locking rod 24 abuts against the outer wall of the aluminum tube to be processed. Under the cooperation of the locking rod 24 and the inner clamping block 21, the tube wall of the aluminum tube 31 can be tightly clamped.

[0032] The aforementioned driving device can be a vertical electric push rod 25, which is connected to the base plate. The free end of the electric push rod 25 is connected to the connecting rod 16. In the initial state, the electric push rod 25 is in an extended state, and the inner support assembly is located at the upper port of the straight cylinder 1201.

[0033] When implementing the device in this embodiment, firstly, a suitable positioning cylinder 12 is assembled according to the specifications of the aluminum tube 31. Specifically: when the aluminum tube 31 to be processed is a straight tube, only the straight cylinder 1201 is assembled. If the aluminum tube 31 to be processed is a bent tube (when the aluminum tube 31 to be processed is a bent tube, the bent part of the aluminum tube is at the high end), then an expansion cylinder 1202 needs to be connected to the upper end of the straight tube. The arc of the expansion cylinder 1202 is consistent with the arc of the bent part of the aluminum tube 31 to be processed. Then, the positioning plate 17 is inserted into the tube to be processed. Inside the lower end of the aluminum tube 31, the operating disc 20 is screwed on so that the two inner clamping blocks 21 exert a certain supporting force on the inner wall of the aluminum tube 31. Then, the aluminum tube 31 is rotated so that the inner and outer clamping blocks are on the same horizontal straight line. The locking rod 24 is screwed on so that the locking rod 24 and the inner clamping blocks 21 tightly clamp the tube wall of the aluminum tube 31 to be processed. Then, the auxiliary device is controlled to move downward through the drive device, thereby driving the aluminum tube 31 to move downward. At the same time, under the action of the straight cylinder 1201, the outward protrusion of the aluminum tube 31 is straightened.

[0034] See Figure 2 As shown, in this embodiment, the driving device can also be a pull rope 26 and a guide wheel 27. The guide wheel 27 is connected to the third fixed rod 28, and the third fixed rod 28 passes through the guide wheel 27. Limiting baffles are provided on the third fixed rod 28 on both sides of the guide wheel 27. The third fixed rod 28 is connected to the second fixed rod 10 through the pull arm 29. The lower end of the pull rope 26 can be manually pulled by the operator after passing around the guide wheel 27. At this time, the inner support assembly is connected to the pull rope 26. By applying traction force to the pull rope, the auxiliary device can be moved downward, thereby moving the aluminum tube downward.

[0035] See Figure 1 , Figure 2 and Figure 6 As shown, in another embodiment of this utility model, when the aluminum tube 31 to be processed has an inward protrusion, a ball 30 can be assembled at the upper end of the aluminum tube 31. The ball 30 is adapted to the inner diameter of the aluminum tube 31, and the ball 30 is connected to the driving device through a traction rope. The power device can make the ball 30 pass through the aluminum tube 31. During the process of the ball 30 passing through the aluminum tube 31, the aluminum tube 31 can be rolled so that the inner hole of the aluminum tube 31 no longer protrudes.

[0036] When implementing the device in this embodiment, firstly, a suitable positioning cylinder 12 is selected according to the specifications of the aluminum tube 31, and the aluminum tube 31 is positioned using the support structure and positioning device. Then, the ball 30 connected with the pull rope 26 is placed on top of the aluminum tube 31 to be processed. At the same time, the lower end of the traction rope is inserted into the aluminum tube 31 and passes through the base 3. The free end of the traction rope is connected to the electric push rod 25 or the free end of the pull rope 26. When the electric push rod 25 retracts, the traction rope will pull the ball 30 through the aluminum tube 31, thereby completing the rolling of the aluminum tube 31.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
