The method of straightening the finned tube mainly includes roll pressing straightening, and the upper and lower two rows of staggered rollers are designed in the skew roll straightening machine.

[0021] Reference Figs. 1-2 The present application proposes an embodiment of the finned tube straightening machine, which includes: a frame 10, on which at least two sets of straightening roller pairs 20 are provided, the heat dissipation tube passes through the straightening roller pairs 20 and rotates around its central axis under the action of the straightening roller pairs 20, and the feed side of the straightening roller pairs 20 is provided with a limiting component 30, the limiting component 30 including two V-shaped limiting structures 40 symmetrically distributed around the central axis, and the V-shaped openings of the limiting structures 40 facing the central axis.

[0022] In this application, the V-shaped openings of the two V-shaped limiting structures 40 are both facing the central axis. Before the heat dissipation pipe enters the straightening roller pair, the two limiting structures 40 limit the end of the heat dissipation pipe through their V-shaped openings, so that the end of the heat dissipation pipe can smoothly enter the straightening roller pair 20, thus solving the problem of collision between the heat dissipation pipe and the straightening roller due to bending.

[0023] Preferably, each of the straightening roller pairs 20 is provided with the limiting component 30 on the feed side to avoid collision with each straightening roller pair.

[0024] Preferably, to allow the heat sink to smoothly enter the V-shaped opening between the two limiting structures 40, the V-shaped opening gradually increases in size from the feed side of the straightener to the other side. Correspondingly, the limiting structure 40 includes two limiting arms 41, forming the V-shaped opening between them, and the thickness of the limiting arms 41 gradually increases from the feed side of the straightener to the other side until the size of the V-shaped opening away from the feed side of the straightener matches the diameter of the heat sink to be straightened.

[0025] In this application, the limiting assembly 30 is mounted on the frame 10 via the lifting assembly 50. Each limiting structure 40 includes a mounting base 42, a mounting member 43, two telescopic members 44, and two limiting arms 41. The mounting base 42 is mounted on the frame 10. One end of the mounting member 43 is mounted on the side of the mounting base 42 near the central axis. The two limiting arms 41 are respectively hinged to the other end of the mounting member 43, and the other ends of the two arms form the V-shaped opening. The two telescopic members 44 are respectively disposed between the two limiting arms 41 and the mounting base 42. The two telescopic members 44 can extend and retract synchronously so that the two limiting arms 41 can rotate synchronously to open or close.

[0026] The V-shaped opening is opened or closed by the synchronous rotation of two telescopic components 44 driving two limiting arms 41, which is suitable for limiting heat dissipation pipes of different diameters.

[0027] Furthermore, the limiting component 30 is mounted on the frame 10 via the lifting component 50.

[0028] After the upper straightening roller is adjusted longitudinally, the longitudinal position of the center of the heat dissipation pipe can be adjusted by the lifting component 50 to ensure that the heat dissipation pipe held by the V-shaped opening coincides with the spatial curve shape of the straightening roller pair 20.

[0029] Specifically, the lifting assembly 50 includes a motor 51 and a lead screw 52. The lead screw 52 is vertically and rotatably mounted on the frame 10. The mounting bases 42 are all screwed onto the lead screw 52. The motor 51 is mounted on the frame 10 and is connected to the lead screw 52 for transmission.

[0030] Referring to the attached drawings, the two ends of the lead screw 52 are respectively mounted on the frame 10 through bearings that rotate with it. One side of the two mounting seats 42 is screwed onto the lead screw 52, ​​and the other side is sleeved on the smooth rod. The motor 51 drives the lead screw 52 to rotate, thereby realizing the rotation of the lead screw 52 and driving the two limiting structures 40 to rise and fall synchronously, realizing the overall lifting and lowering of the two V-shaped openings.

[0031] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
