[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] Example:

[0032] An automatic pipe bending device, such as Figure 1-2 As shown, it includes a workbench 1, a bending wheel 2, a power assembly 3 and a pressure wheel assembly 4. Among them, the workbench 1 serves as a fixed foundation for the entire device and is used to carry the pipe bending equipment. The power assembly 3 is installed inside the workbench 1. The bending wheel 2 is installed above the workbench 1. A central shaft 5 is provided in the middle of the bending wheel 2. The bending wheel 2 is connected to the power assembly 3 through the central shaft 5 to drive the bending wheel 2 to rotate through the power assembly 3. In addition, a turntable 6 is provided between the bending wheel 2 and the workbench 1. A bearing sleeve 61 is installed on the inner side of the turntable 6. The turntable 6 is sleeved on the central shaft 5 through the bearing sleeve 61, which not only effectively improves the flexibility of the rotation of the turntable 6, so that the turntable 6 can rotate relative to the bending wheel 2, but also reduces the direct contact between the turntable 6 and the central shaft 5, thereby reducing friction and wear. The pressure wheel assembly 4 is located on one side of the turntable 6, and the distance between the pressure wheel assembly 4 and the bending wheel 2 can be adjusted.

[0033] Specifically, such as Figure 1 and Figure 3 As shown, the power assembly 3 includes a drive motor 31 and a transmission member 32. The drive motor 31 is fixed inside the workbench 1 and is used to provide power for the rotation of the entire bending wheel 2. The transmission member 32 is connected between the drive motor 31 and the central shaft 5 and is used to transmit the power of the motor to the central shaft 5. The central shaft 5 not only plays a connecting role, but also transmits power to the bending wheel 2 through its own rotation, thereby realizing the rotation function of the bending wheel 2. Specifically, the transmission member 32 adopts the matching form of a driving wheel 321 and a driven wheel 322. The driving wheel 321 is connected to the output shaft of the drive motor 31, and the driven wheel 322 is connected to the central shaft 5. The driving wheel 321 and the driven wheel 322 transmit power through meshing, which ensures the stability and smoothness of the rotation and improves the power transmission efficiency.

[0034] like Figure 1 and Figure 4As shown, the pressure roller assembly 4 includes a pressure roller 41 and an adjusting member 42. The pressure roller 41 is connected to the end of the adjusting member 42 on the side close to the bending wheel 2. The distance between the pressure roller 41 and the bending wheel 2 can be adjusted by the adjusting member 42. Specifically, the adjusting member 42 includes a mounting seat 421, a movable block 422, a screw 423 and a sleeve 424. The mounting seat 421 is welded to the edge of the turntable 6 and is used to fix the entire adjusting member 42. At the same time, when the turntable 6 rotates, the adjusting member 42 and the turntable 6 rotate synchronously. The movable block 422 is movably connected to the mounting seat 421. The pressure roller 41 is installed on the side of the movable block 422 close to the bending wheel 2, and the movable block 422 can be moved and adjusted according to actual needs. The sleeve 424 is fixedly connected to the mounting seat 421 and is located on the side of the movable block 422 away from the bending wheel 2, and is used to cooperate with the screw 423. The screw 423 is sleeved in the sleeve 424, and one end of the screw 423 is connected to the moving block 422. The rotation of the screw 423 drives the moving block 422 to move in the mounting seat 421 , thereby adjusting the position of the pressure roller 41 .

[0035] like Figure 4 As shown, a slot 421a is provided on the inner sidewall of the mounting base 421, and a slider 422a is provided on the sidewall of the movable block 422. The slider 422a is embedded in the slot 421a. The slider 422a moves smoothly within the slot 421a, adjusting the position of the pressure roller 41. This makes the position adjustment of the pressure roller 41 more precise, helps improve the accuracy of pipe bending, and improves the quality of pipe processing.

[0036] In addition, if Figure 4 As shown, a limit plate 425 is welded to the mounting base 421. The limit plate 425 has two strip-shaped holes 425a formed therein. Fixing members 426 are connected within the strip-shaped holes 425a. The limit plate 425 is connected to the movable block 422 via the fixing members 426. The strip-shaped holes 425a provide a certain adjustment range for the movable block 422, thereby adjusting the position of the pressure roller 41. The fixing members 426 can be bolts. When the movable block 422 drives the pressure roller 41 to a predetermined position, the bolts are tightened to secure the movable block 422. This reduces movement of the movable block 422 during the pipe bending process and improves the pipe processing quality.

[0037] like Figure 1 As shown, a die 7 is provided on one side of the pressing roller 41. Semicircular grooves are formed on the sidewalls of the die 7 and the outer wall of the bending wheel 2. The grooves match the shape of the outer wall of the pipe. By replacing the die 7 with different sizes, pipes of different diameters can be processed, increasing the adaptability and flexibility of the equipment. Furthermore, the grooves can reduce pipe deviation during the bending process, further improving the processing quality of the pipe and reducing the rate of product rejection.

[0038] Working Principle: During operation, the metal tube to be processed is first placed on the workbench 1. The tube and die 7 are pressed tightly between the bending wheel 2 and the pressure roller 41 using the pressure roller assembly 4. The tube is then secured using the adjustment member 42. The drive motor 31 is activated, driving the bending wheel 2 to rotate. As the bending wheel 2 rotates, it pushes the pressure roller assembly 4 to bend the metal tube along the predetermined bending radius. After processing is completed, the adjustment member 42 is moved to increase the distance between the pressure roller 41 and the bending wheel 2, and the processed metal tube is removed.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
