The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0039] As Figures 1 to 3As shown in the figure, this embodiment provides a pipeline bending device, which includes a workbench surface 1, a fixed mold 2, a bending component 3, a pipeline positioner 4 and a driving component 5. The fixed mold 2 is arranged on one side of the workbench surface 1, and an arc section 21 is arranged on the outer peripheral wall of the fixed mold 2; the bending component 3 includes a swing rod 31 and a bending wheel 32. One end of the swing rod 31 is rotatably arranged on the workbench surface 1, and the rotating shaft of one end of the swing rod 31 is located at the center of the circle of the arc section 21. The bending wheel 32 is rotatably matched with the other end of the swing rod 31. The rotating shaft of the bending wheel 32 is parallel to the rotating shaft of one end of the swing rod 31. The bending wheel 32 is located on one side of the workbench surface 1 and is arranged opposite to and at intervals from the arc section 21; the pipeline positioner 4 is fixedly arranged on one side of the workbench surface 1 and is used for fixing the pipeline 100; the driving component 5 drives one end of the swing rod 31 to rotate. When the pipeline bending device works, one end of the pipeline 100 is passed between the bending wheel 32 and the arc section 21 of the fixed mold 2, so that the bending wheel 32 and the arc section 21 of the fixed mold 2 are respectively in contact with the pipeline 100. The other end of the pipeline 100 is fixed by the pipeline positioner 4. When the driving component 5 drives the swing rod 31 to swing, the bending wheel 32 swings around one end of the swing rod 31. When the pipeline 100 is bent on the arc section 21 of the fixed mold 2, the pipeline 100 is bent into the same radian as the arc section 21. The pipeline bending device uses the driving component 5 as a power source to bend the pipeline 100, which improves the work efficiency, reduces the labor input, and improves the accuracy of bending positioning.

[0040] Optionally, the workbench surface 1 is provided with an arc groove 11, and the arc groove 11 is arranged on the outer peripheral side of the arc section 21; the bending component 3 further includes a rotating shaft 33. The swing rod 31 is located on the other side of the workbench surface 1. The rotating shaft 33 is arranged at the other end of the swing rod 31. The rotating shaft 33 passes through the arc groove 11 and is rotatably matched with the bending wheel 32 on one side of the workbench surface 1; the driving component 5 is located on the other side of the workbench surface 1. In this embodiment, both the rotating rod and the driving component 5 are arranged on the other side of the workbench surface 1, so that only the fixed mold 2, the bending wheel 32 and the pipeline positioner 4 that require manual operation are arranged on one side of the workbench surface 1. This setting can facilitate the operation of the staff on the one hand, and can avoid the driving component 5 and the swing rod 31 from causing harm to the staff during work on the other hand.

[0041] Optionally, a waist-shaped hole is provided at the other end of the swing rod 31, and the waist-shaped hole extends along the length direction of the swing rod 31; the bending component 3 further includes a locking nut 34, the rotating shaft 33 includes a rotating shaft portion 331 and a threaded portion 332, the rotating shaft portion 331 is rotatably matched with the bending wheel 32, the threaded portion 332 passes through the waist-shaped hole and is screwed with the locking nut 34, and the diameters of the rotating shaft portion 331 and the outer diameter of the locking nut 34 are both larger than the width of the waist-shaped hole. In this embodiment, by adjusting the position of the threaded portion 332 in the waist-shaped hole, the spacing distance between the bending wheel 32 and the fixed mold 2 can be adjusted, and thus pipelines 100 of different sizes can be adapted. When it is necessary to adjust the position of the threaded portion 332 in the waist-shaped hole, loosen the locking nut 34, so that the spacing between the locking nut 34 and the rotating shaft portion 331 is larger than the thickness of the swing rod 31. At this time, the threaded portion 332 can slide in the waist-shaped hole. When it is necessary to fix the threaded portion 332 relative to the waist-shaped hole, tighten the locking nut 34, so that the locking nut 34 and the rotating shaft portion 331 clamp the swing rod 31. At this time, the rotating shaft 33 is fixed relative to the swing rod 31.

[0042] Optionally, a plurality of limiting grooves are sequentially arranged along the length direction of the swing rod 31 on the surface of the swing rod 31 opposite to the rotating shaft portion 331, and a limiting protrusion protrudes from the surface of the rotating shaft portion 331 opposite to the swing rod 31, and the limiting protrusion is selectively inserted into one of the limiting grooves. In this embodiment, when the swing rod 31 swings, the bending wheel 32 is subjected to a force of the pipeline 100 along the length direction of the swing rod 31. At this time, it is very easy to cause the rotating shaft 33 to slide relative to the swing rod 31 in the waist-shaped hole. To avoid this phenomenon, when the position of the rotating shaft 33 relative to the swing rod 31 is adjusted, at this time, the limiting protrusion is inserted into the corresponding limiting groove. Then, when the locking nut 34 is tightened, this setting can further prevent the rotating shaft 33 from moving relative to the swing rod 31.

[0043] Optionally, the driving component 5 includes a driver 51 and a fixing frame 52. The fixing frame 52 is fixedly connected to the other side of the workbench surface 1, the driver 51 is fixed on the fixing frame 52, and one end of the swing rod 31 is fixedly connected to the output shaft of the driver 51. In this embodiment, the fixing frame 52 includes two vertical plates and a horizontal support plate. One ends of the two vertical plates are respectively fixedly connected to the other side of the workbench surface 1, and the other ends of the two vertical plates are respectively fixedly connected to both ends of the horizontal support plate, so that the horizontal support plate is spaced from the workbench surface 1. One end of the swing rod 31 is located between the horizontal support plate and the workbench surface 1. The driver 51 is fixed on the horizontal support plate, and the output shaft of the driver 51 passes through the horizontal support plate and is fixedly connected to one end of the swing rod 31.

[0044] Optionally, the driver 51 includes a motor and a speed reducer. The output shaft of the motor is drivingly connected to the input shaft of the speed reducer, and the output shaft of the speed reducer is fixedly connected to one end of the swing rod 31. In this embodiment, during the process of the bending wheel 32 bending the pipeline 100 on the arc section 21 of the fixed mold 2, the swing rod 31 needs to provide a large torque. Therefore, the speed reducer can play the role of reducing speed and increasing torque to provide sufficient torque for the swing rod 31.

[0045] Optionally, the pipeline locator 4 is located on the tangent line at one end of the arc section 21. In this embodiment, this setting can prevent the pipeline 100 from bending at one end of the arc section 21.

[0046] Optionally, the arc section 21 is a U-shaped concave surface. In this embodiment, this setting enables the arc section 21 to better fit the peripheral wall of the pipeline 100, thereby limiting the pipeline 100 and preventing the pipeline 100 from detaching from the arc section 21.

[0047] Optionally, the outer peripheral wall of the bending wheel 32 is a U-shaped concave surface. In this embodiment, this setting enables the peripheral wall of the bending wheel 32 to better fit the peripheral wall of the pipeline 100, thereby limiting the pipeline 100 and preventing the pipeline 100 from detaching from the bending wheel 32.

[0048] Optionally, the pipeline bending device further includes a driving handle fixedly connected to the other end of the swing rod 31. In this embodiment, when the driving assembly 5 fails or there is a power outage, the staff can temporarily drive the swing rod 31 to swing through the driving handle, thereby realizing the bending of the pipeline 100.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
