[0025] like Figure 1 and Figure 2 As shown, a thin-walled metal pipe end rounding and shaping device comprises a pair of symmetrically distributed tripods 1, clamping rollers 12 penetrating part of the plate body are connected to the inside of the three sides of the tripod 1 through springs 11, grooves 15 corresponding to the springs 11 are arranged on the three sides of the tripod 1, and a limiting member 16 corresponding to the groove 15 and fixedly connected to the spring 11 is arranged in the groove 15, a T-shaped limiting rod 17 inserted into the clamping roller 12 is fixedly connected to the side of the limiting member 16 away from the tripod 1, a fixed gear 14 is connected to the middle of the clamping roller 12 through a connecting shaft 13, a driving structure 2 meshing with the fixed gear 14 is arranged on one side of the fixed gear 14, and the driving structure 2 comprises a movable gear 21 corresponding to the fixed gear 14, and an adjusting arm 22 is movably connected to the side of the movable gear 21 away from the connecting shaft 13

[0026] In the present embodiment, a symmetrically distributed tripod 1 is provided to adaptively clamp the tube body, the outer wall of the tube body is clamped by means of a clamping roller 12, and the tube body is clamped under the pull of a spring 11. At this time, the driving structure 2 is placed inside the tube body, and the movement of the movable gear 21 drives the adjusting arm 22 to rotate inside the tube body along the fixed gear 14. The adjusting arm 22 is close to the inner wall of the tube body to achieve rounding and shaping. By changing the diameter of the fixed gear 14, the movable gear 21 adaptively changes its position with the help of a push spring 29, thereby completing the position of the clamping arm 22 and adapting to different tube bodies.

[0027] like Figure 3 and Figure 4 As shown, the fixed gear 14 is provided with a polygonal limit block 18 that penetrates itself and is fixedly connected by the connecting shaft 13, an outer shell 23 that is penetrated by the connecting shaft 13 and connected to the adjusting arm 22 is provided above the polygonal limit block 18, and the upper part of the connecting shaft 13 is connected to another tripod 1 through another connecting shaft with a diameter larger than itself and inserted by itself, a sliding groove 24 is provided inside the outer shell 23 that penetrates itself, and a movable groove 25 that penetrates the side wall of the sliding groove 24 and has a width smaller than the sliding groove 24 is provided on the side of the sliding groove 24 close to the movable gear 21, the movable gear 21 is connected to a driving motor 27 placed in the sliding groove 24 through a driving shaft 26 corresponding to the movable groove 25, a universal connector 28 connected to the adjusting arm 22 is fixedly connected to the driving motor 27 on the side close to the adjusting arm 22, and a push spring 29 placed in the outer shell 23 is provided at the other end of the driving motor 27.

[0028] In this embodiment, the polygonal limit block is fixed inside the fixed gear 14 by the connecting shaft 13, ensuring the stable connection between the fixed gear and the adjustment arm 22. The outer shell 23 surrounds and supports the polygonal limit block and the adjustment arm, providing additional structural strength and support, ensuring the stability and accuracy of the adjustment arm during operation; a movable groove 25 is provided in the sliding groove 24. This design enables the movable gear 21 to move precisely axially along the sliding groove, thereby controlling the position of the adjustment arm; the structure of the sliding groove ensures the stability and accuracy of the movable gear, enabling it to precisely adjust and correct the inner wall of the tube body during operation; the drive motor controls the movement of the movable gear through the drive shaft 26 to achieve precise adjustment of the adjustment arm, and the push spring is located inside the outer shell to provide appropriate reverse force for the drive motor, ensuring the stability and reliability of the adjustment arm under various operating conditions.

[0029] In summary, these structural designs effectively support and optimize the functions of the thin-walled metal pipe port rounding and shaping device. They ensure the accuracy, stability and reliability of the equipment during operation, thereby ensuring that the rounding and shaping process can accurately restore the standard round shape of the pipe port, improving the efficiency of the device and the controllability of operation.

[0030] When in use, ensure that all parts of the device are intact, including the tripod, clamping roller, fixed gear, movable gear, adjustment arm, etc. are in normal working condition. Check whether the power connection and drive motor are normal. Select a fixed gear 14 of appropriate size according to the diameter of the thin-walled metal tube to be rounded and shaped. If necessary, replace the fixed gear to ensure that it can mesh correctly with the movable gear 21; place the thin-walled metal tube to be rounded and shaped between a pair of symmetrically distributed tripods 1. Ensure that the tube body port is located at the center of the device; use the clamping roller 12 on the tripod 1 to clamp the outer wall of the tube body. Under the action of the spring 11, the clamping roller 12 will cling to the outer wall of the tube body to achieve a stable clamping; place the driving structure 2 (including the movable gear 21 and the adjustment arm 22) inside the tube body. The movable gear 21 can automatically adjust its position according to the inner diameter of the tube body through the design of the sliding groove 24 and the movable groove 25; start the drive motor 27 and drive the movable gear 21 to move through the drive shaft 26. The movable gear 21 meshes with the fixed gear 14, driving the adjustment arm 22 to rotate inside the tube body; the adjustment arm 22 is close to the inner wall of the tube body, and with the rotation, the inner wall of the tube body is evenly pressed to achieve rounding and shaping. The push spring 29 ensures that the adjustment arm 22 can adapt to the slight changes in the inner wall of the tube body; observe the shaping process to ensure that the adjustment arm 22 is evenly in contact with the inner wall of the tube body. If necessary, the speed or pressure of the drive motor 27 can be fine-tuned; when the tube body port returns to the standard circle, stop the drive motor 27 to stop the adjustment arm 22 from rotating; release the clamping roller 12, and carefully remove the thin-walled metal tube that has completed rounding and shaping from the device. Measure and inspect the shaped tube body port to ensure that the required roundness and size requirements are met. After completing the operation, clean the device, check whether each component is worn or damaged, and perform necessary maintenance to ensure performance and accuracy when used next time.

[0031] Through these steps, operators can effectively use the thin-walled metal tube port rounding and shaping device to achieve precise rounding and shaping of thin-walled metal tube ports of various specifications, thereby improving the quality of the tube body and subsequent performance.

[0032] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
