[0037] In one embodiment, the traction device 4 is connected to the telescopic device 32. In this way, the traction device 4 pulls the telescopic device 32 to drive the piston 31 to move synchronously.

[0038] Preferably, the telescopic device 32 is a jack or a cylinder.

[0039] Preferably, the piston 31 is made of nylon to avoid damage to the surface of the aluminum tube 5.

[0040] In one embodiment, the clamping device 2 includes a first guide rail 21 and a second guide rail 22 arranged side by side with the first guide rail 21 , and the first guide rail 21 and the second guide rail 22 are both installed on the workbench 1 .

The provision of multiple fixing seats 23 facilitates securing the aluminum tube 5 and prevents it from shifting during the shaping process. Furthermore, because the multiple fixing seats 23 are slidably connected to the first guide rail 21, the spacing between adjacent fixing seats 23 can be adjusted, thereby strengthening the localized force support of the aluminum tube 5.

[0042] In one embodiment, the fixing seat 23 is provided with a passage that runs transversely through both end surfaces of the fixing seat 23 and through which the aluminum tube 5 can pass. The top of the fixing seat 23 is provided with an opening that communicates with the passage and through which the aluminum tube 5 can pass.

[0043] In one embodiment, the clamping device 2 further includes a plurality of stoppers 24, which are slidably connected to the second guide rail 22 and are used to press the aluminum tube 5 into the channel.

[0045] Preferably, the second driving device 243 is a cylinder.

[0046] In one embodiment, the clamping device 2 further includes a third driving device 25 for controlling the reciprocating motion of the limiting device 24 along the second guide rail 22 , and the third driving device 25 is installed on the workbench 1 .

[0047] In one embodiment, the clamping device 2 also includes a fixing device 27 and a third guide rail 26 arranged side by side with the first guide rail 21, and the first guide rail 21 is located between the second guide rail 22 and the third guide rail 26; the fixing device 27 is slidably connected to the third guide rail 26 and is used to press the aluminum tube 5 into the channel.

[0049] In one embodiment, the traction device 4 includes a cylinder 41 and a power device 42 uniformly distributed around the circumference of the cylinder 41; the cylinder 41 is connected to the telescopic device 32 of the correction device 3; the power device 42 includes a first elastic member 421, a second elastic member 422, a hinged arm 423, and a drive belt 424; one end of the hinged arm 423 is hinged to the cylinder 41, and the other end of the hinged arm 423 is hinged to the drive belt 424; the first elastic member 421 presses the drive belt 424 onto the inner wall of the aluminum tube 5; the cylinder 41 is provided with a guide hole along the axial direction of the cylinder 41; a guide seat is slidably connected in the guide hole; one end of the first elastic member 421 is hinged to the cylinder 41, and the other end of the first elastic member 421 is connected to the guide seat; one end of the second elastic member 422 is hinged to the drive belt 424, and the other end of the second elastic member 422 is hinged to the guide seat. In this way, the driving belt 424 is pressed onto the driving belt 424 by the cooperation of the first elastic member 421 and the second elastic member 422.

[0050] The driving belt 424 is a prior art and will not be described in detail here.

[0051] like Figures 7-9 As shown, in one embodiment, the aluminum tube 5 shaping tooling structure also includes a cutting device 6; the cutting device 6 is located at the lower station of the clamping device 2; the cutting device 6 includes a frame 61, a turntable 62, a rotating motor 63, a plurality of slide rails 64 and a slider corresponding to each slide rail 64; the turntable 62 is provided with a through hole for the aluminum tube 5 to pass through, and the plurality of slide rails 64 are radially arranged around the radial direction of the through hole; the slider is slidably connected to the slide rail 64; the rotating motor 63 is installed on the frame 61 and the output end of the rotating motor 63 is connected to the turntable 62.

[0052] The cutting device 6 further includes a cutter 66 and an abutment wheel 65 corresponding to each slider. The abutment wheel 65 is mounted on the slider. The cutter 66 is mounted on any slider and does not interfere with the abutment wheel 65 .

[0053] Preferably, the slide rail 64 and the slider are replaced by a linear module, which controls the abutment wheel 65 to abut the aluminum tube 5 passing through the through hole. At the same time, as the abutment wheel 65 abuts the aluminum tube 5, the cutter 66 also abuts the aluminum tube 5 to achieve cutting of the aluminum tube 5.

[0054] In this way, after the aluminum tube 5 is shaped, the aluminum tube 5 can be cut simultaneously.

[0055] The technical features of the above-mentioned embodiments can be combined arbitrarily.
