[0033] like Figures 1 to 12 As shown in the schematic diagram of an embodiment of the pipe bending tool of this utility model, it includes a support part, which serves as the core force-bearing skeleton of the entire pipe bending tool and can provide sufficient support for other components; a fixing part, which is connected to the support part and is used to fix the pipe 6 during the pipe bending process; and a telescopic part 1 that can be rotatably connected to the pipe 6. The telescopic part 1 is connected to the support part, and the length of the telescopic part 1 can be adjusted to cooperate with the fixing part to realize the pipe bending process.

[0034] In this embodiment, the fixing part includes an arc-shaped support 2 connected to the supporting part, and the arc-shaped support 2 has a groove 21. This embodiment can avoid wrinkles or cracks caused by manual bending, and has a simple structure and occupies little space.

[0035] In one embodiment, there is one telescopic part 1, and the fixing part further includes a fixing component. The fixing component and the telescopic part 1 are respectively disposed on both sides of the arc-shaped support 2. The fixing component is detachably connected to the pipe 6. When the pipe 6 is bent, the fixing component and the telescopic part 1 are respectively connected to the pipe 6. The pipe 6 contacts the arc-shaped support 2 and is disposed in the groove 21. One end of the pipe 6 can be fixed by the fixing component and the arc-shaped support 2. The pipe 6 can be bent by adjusting the length of the telescopic part 1. Preferably, in this embodiment, the fixing component and the telescopic part 1 have the same structure. The fixing component can be used not only for fixing one end of the pipe 6, but also for bending the pipe 6. That is, there are two telescopic parts 1, which are respectively disposed on both sides of the arc-shaped support 2. In this embodiment, the two telescopic parts 1 can be symmetrically distributed. When a small-angle pipe 6 bending process is required, only the length of one side of the telescopic part 1 needs to be adjusted to meet the processing requirements. When a large-angle pipe 6 bending process is required, the lengths of the two telescopic parts 1 can be adjusted in an orderly manner to meet the processing requirements.

[0036] The main steps for using this utility model are as follows:

[0037] Each telescopic part 1 is connected to the pipe 6. In this embodiment, the two ends of the pipe 6 are respectively connected to the corresponding telescopic part 1. The length of the corresponding telescopic part 1 is adjusted to move the pipe 6. The pipe 6 is brought into contact with the arc-shaped support 2 and the pipe 6 is placed in the groove 21. The telescopic part 1 can cooperate with the arc-shaped support 2. The arc-shaped support 2 can support the pipe 6. The groove 21 cooperates with the telescopic part 1 to play a locking role. The length of the telescopic part 1 is adjusted to bend the pipe 6.

[0038] In this embodiment, the telescopic part 1 is rotatably connected to the support part to adjust the included angle between the telescopic part 1 and the support part. This embodiment is better suited for irregular bending of pipes 6 of different sizes and specifications, and can meet the arbitrary curvature adjustment of pipes 6 of different lengths or diameters within a certain range; this embodiment is also suitable for complex usage environments, has wide applicability, and is easy to promote and apply.

[0039] In this embodiment, the telescopic part 1 includes a control member 11 and a telescopic member 12. The telescopic member 12 is rotatably connected to the pipe 6 and threadedly connected to the control member 11. The control member 11 is rotatably connected to the support part. By rotating the control member 11, the length of the telescopic part 1 can be adjusted to bend the pipe 6. Preferably, the telescopic member 12 is disposed within the control member 11. The telescopic part 1 also includes a connecting member 13, which is movably embedded within the control member 11 and rotatably connected to the control member 11. The connecting member 13 is rotatably connected to the support part. Preferably, the connecting member 13 can be hinged to the support part via a pivot 51. The connecting member 13 can both support the axial rotation of the control member 11, allowing the control member 11 to rotate itself to adjust the length of the telescopic part 1, and can also be hinged to the support part, allowing the control member 11 to rotate relative to the support part to adjust the angle between the telescopic part and the support part. In this embodiment, the stress caused by bending of the pipe 6 can be converted into axial tension. Through a threaded connection design and by connecting the pipe 6 to the telescopic member 12 to restrict the rotation of the telescopic member 12, a rotation control member 11 is established. This facilitates the movement of the telescopic member 12 relative to the control member 11 in the length direction, allowing for easy length adjustment of the telescopic part 1 and providing sufficient axial tension for bending of the pipe 6. The control member 11 is equipped with a handle 111 for rotation, which also facilitates length adjustment of the telescopic part 1, improving efficiency and reducing labor intensity.

[0040] In this embodiment, the support part includes a support rod 3 and a reinforcing rod 4. The fixing part and the telescopic part 1 are respectively connected to the support rod 3, and the two ends of the reinforcing rod 4 are respectively connected to the support rod 3 and the fixing part. Preferably, the support rod 3 and the reinforcing rod 4 are hollow inside to reduce the weight of the component. The arc-shaped support 2 is connected to the support rod 3, the reinforcing rod 4 is perpendicularly connected to the support rod 3, the end of the arc-shaped support 2 is connected to the reinforcing rod 4, the middle part of the arc-shaped support 2 is connected to the support rod 3, and the fixing part is connected to the support part to form a symmetrical structure with the support rod 3 as the axis. In this embodiment, the arc-shaped support 2 is used as a support groove for the bending of the pipe 6. The middle part of the arc-shaped support 2 is welded to the support rod 3, and the two ends of the arc-shaped support 2 are provided with reinforcing rods 4 for reinforcement. The three points can be connected by welding. The multi-support point reinforcement structure can ensure the structural strength of the arc-shaped support 2, not only preventing the arc-shaped support 2 from deforming after long-term use and ensuring the service life of the tool, but also providing stable support for the arc-shaped support 2 and ensuring the bending processing effect of the pipe 6. In this embodiment, the control component 11 is rotatably connected to the support rod 3 via the connector 13.

[0041] In this embodiment, a sleeve 5 detachably connected to the pipe 6 is also included, and the telescopic part 1 is rotatably connected to the sleeve 5. Preferably, the sleeve 5 includes a locking component and two oppositely arranged limiting members. The opposite sides of the two limiting members are curved to fit the pipe 6. The two limiting members are movably connected through the locking component to adjust the spacing, thereby enabling the sleeve 5 to be fitted onto different pipes 6 and detachably connected to the pipe 6. The locking component can be an adjusting screw and a nut threadedly connected to the adjusting screw. The sleeve 5 can be rotatably connected to the telescopic part through a connecting shaft 51. Preferably, the sleeve 5 can be rotatably connected to the telescopic part 12 through a rotating shaft 51. This embodiment can withstand shear force while ensuring rotational function.

[0042] The specific usage process of this embodiment is as follows:

[0043] like Figure 10 As shown, adjust the relative positions of the arc-shaped support 2 and the two sleeves 5 respectively located at the ends of the corresponding telescopic parts 1 so that the three are in a straight line. Specifically, while preventing the telescopic part 12 from rotating through the sleeves 5, the operator can rotate the control component 11 and drive the telescopic part 12 to move and extend through the threaded force until the lower edges of the sleeves 5 on both sides are flush with the bottom of the groove 21 of the arc-shaped support 2 and are in a straight line. After passing through one sleeve 5, the pipe 6 to be bent is placed in the groove 21 of the arc-shaped support 2, and then passed through the other sleeve 5.

[0044] Rotating the corresponding control component 11 adjusts the length of the corresponding telescopic part 1. At this time, the arc-shaped support 2 serves as a fulcrum in the middle of the pipe 6. The clamp 5 is pulled by the telescopic part 1 to bend the pipe 6. The middle of the pipe 6 is limited by the groove 21 to hold it in place, and the end of the pipe 6 moves under force, thus achieving the bending process of the pipe 6. In this embodiment, the pipe 6 can be bent along any tangent of the arc-shaped support 2; and when one telescopic part 1 extends or retracts to bend one end of the pipe 6, the other telescopic part 1 can cooperate with the arc-shaped support 2 to fix the other end of the pipe 6. Finally, the bending angle of the pipe 6 can be finely adjusted according to requirements to ensure processing quality and meet the requirements for bending at any angle within a certain range. Figure 11 As shown, when pipe 6 needs to be bent at a small angle, only the length of the telescopic part 1 on one side needs to be adjusted to meet the processing requirements; for example... Figure 12 As shown, when the pipe 6 needs to be bent at a large angle, the lengths of the expansion joints 1 on both sides can be adjusted in an orderly manner to meet the processing requirements.

[0045] In this embodiment, the bending stress of the pipe 6 is converted into axial tension through the telescopic part 1. The threaded adjustment can more accurately control the bending angle of the pipe 6. With the support and fixation of the arc-shaped brace 2, the bending rate of the pipe 6 is guaranteed to meet the requirements. It can also avoid the inside of the pipe 6 from being affected by manual bending, which may cause wrinkles or breakage. This can improve the bending processing efficiency and quality, reduce the material loss rate and save processing costs, and speed up the construction progress.

[0046] This invention can reduce the labor intensity of personnel in bending metal pipes 6, avoid the difficulty in controlling the bending degree caused by manual bending, and use threaded rotation control to replace manual bending, which can accurately control the bending angle of pipe 6. The pipe bending tool has a simple structure, low manufacturing cost and small space occupation, and wide applicability.

[0047] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
