For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0021] In the description of this technology, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this technology can be understood according to specific circumstances.

[0022] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0023] See also Figure 1-4The utility model is a mechanical seal pipe bending device, comprising a processing table 1, a bending structure and a positioning structure, the bending structure comprising a bending plate 4 and a handle 5, the front and back sides of the bending plate 4 are fixedly connected to the limit baffle 3, when the pipeline passes through the bending plate 4, it is located between the two limit baffles 3, the handle 5 is fixedly connected to the middle part of the limit baffle 3 near the front of the bending plate 4, a positioning pin 2 is fixedly connected to the front of the processing table 1, the bending plate 4, the handle 5 and the limit baffle 3 all pass through the positioning pin 2 and are rotatably connected to the positioning pin 2, a fixing part 6 is arranged near the right side of the bending structure, the positioning structure is arranged on the front of the processing table 1 and near the upper right position of the bending structure, the positioning structure comprises a fixed roller assembly and a movable roller assembly, and a gap is left between the fixed roller assembly and the movable roller assembly for the pipeline to pass through.

[0024] like Figure 1 and Figure 2 As shown, in this embodiment, the fixed roller assembly includes a first fixed seat 9 and a first U-shaped roller 10, the first fixed seat 9 is fixedly connected to the processing table 1, and the first U-shaped roller 10 is rotatably connected to the front of the first fixed seat 9, and the movable roller assembly includes a mounting seat 11, a hydraulic telescopic rod 12, a second fixed seat 13, a second U-shaped roller 14 and a third U-shaped roller 15, the mounting seat 11 is fixedly connected to the right side of the front of the processing table 1, the hydraulic telescopic rod 12 is fixedly connected to the left side of the mounting seat 11, the second fixed seat 13 is fixedly connected to the left side of the hydraulic rod output end, and the second U-shaped roller 14 and the third U-shaped roller 15 are rotatably connected to the top and bottom of the front of the second fixed seat 13 respectively.

[0025] Furthermore, in order to ensure that the calibration work is completed when the pipe is inserted between the first U-shaped roller 10 and the second U-shaped roller 14, the rightmost side of the bending plate 4 is in the same vertical plane as the rightmost side of the first U-shaped roller 10; the center of the first U-shaped roller 10 and the center of the second U-shaped roller 14 are in the same horizontal plane, and the centers of the second U-shaped roller 14 and the third U-shaped roller 15 are in the same vertical plane.

[0026] Through the above technical solution, when the pipe is inserted between the first U-shaped roller 10 and the second U-shaped roller 14, the bending work can be started directly, which greatly improves the work efficiency.

[0027] A through hole is provided in the center of the fixing member 6 for the pipeline to pass through. The fixing member 6 is detachably installed between the two limit baffles 3 by means of screws.

[0028] It should be noted that the function of the fixing member 6 is to drive one end of the pipe to bend, so the diameter of the through hole on the fixing member 6 must be the same as the diameter of the pipe. When bending pipes of different diameters, it is only necessary to replace the fixing member 6 with the through hole of the same diameter. The bending structure is universal, which further reduces the cost of use.

[0029] See also Figure 2 , through the above technical scheme, when the device is in use, first the bottom end of the pipe is placed on the surface on the right side of the first U-shaped roller 10, and then the hydraulic telescopic rod 12 is started to make the output end of the hydraulic telescopic rod 12 extend to the left until the left side of the second U-shaped roller 14 is in contact with the surface of the pipe, and then the hydraulic telescopic rod 12 is stopped, and then the pipe is pushed downward until the bottom end of the pipe passes through the through hole of the fixing member 6. At this time, the surface of the pipe is respectively in contact with the first U-shaped roller 10, the second U-shaped roller 14, the surface of the bending plate 4 and the surface of the third U-shaped roller 15. After that, the worker can hold the handle 5 by hand and rotate it clockwise to bend the pipe to the angle he wants. After the bending is completed, it is only necessary to start the hydraulic telescopic rod 12 to retract the output end of the hydraulic telescopic rod 12 to release the pipe, and the worker can directly pull the bent pipe out of the fixing member 6.

[0030] In some other embodiments, an angle scale line 8 is provided on the processing table 1 near the positioning pin 2 , and a pointer 7 is fixedly connected to the limit baffle 3 near the bottom.

[0031] It should be noted that if Figure 1 As shown, when the device is in the initial state, the pointer 7 just points to the 0° position of the angle scale line 8. Therefore, when bending the pipe, the staff can observe the positional relationship between the pointer 7 and the angle scale line 8, that is, the degree indicated by the pointer is the degree of the pipe bending, and bend the pipe to the angle they need, which is very convenient to use.

[0032] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
