Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0018] The following will be combined with the instructions attached Figure 1-3 And specific implementation methods are used to describe the above technical solutions in detail:

[0019] The utility model provides a pipe bending device, comprising a bottom plate 1, a support rod 2 is symmetrically arranged below the bottom plate 1, a fixed disc 3 is fixedly connected to the bottom plate 1, a through groove 4 is opened at the center of the fixed disc 3, the through groove 4 penetrates the bottom plate 1 downward, a motor 5 is fixedly connected to the bottom plate 1, the output shaft of the motor 5 passes through the through groove 4 and extends to the top of the fixed disc 3 and is fixedly connected to a cross bar 6, a side of the cross bar 6 away from the fixed disc 3 is fixedly connected to a vertical rod 7, a lower end of the vertical rod 7 is fixedly connected to a moving disc 8, the moving disc 8 is slidably connected to the bottom plate 1, a groove 9 is opened around the side of the moving disc 8 and the fixed disc 3, a push-out mechanism is arranged on one side of the bottom plate 1, a collecting frame 10 is fixedly connected to the other side of the bottom plate 1, and a fixed structure is arranged on the side of the bottom plate 1 close to the push-out mechanism. When bending the pipe, one side of the pipe is inserted between the fixed disc 3 and the movable disc 8, so that the pipe is located in the groove 9 between the disc and the movable disc 8, and the pipe is fixed by the fixed structure, and then the motor 5 is started to rotate the electric cross bar 6, thereby driving the vertical rod 7 and the movable disc 8 to rotate around the axis of the fixed disc 3, so as to bend the pipe. The bending degree of the bent pipe is generally between 0 degrees and 180 degrees, and the common degrees are 45 degrees, 90 degrees, and 135 degrees. The bending degree of the pipe is determined by the rotation angle of the movable disc 8. After the bending is completed, the movable disc 8 is reset, and the fixed structure no longer fixes the pipe. Then the pushing mechanism starts to work, thereby pushing the bent pipe out from between the fixed disc 3 and the movable disc 8 until it falls into the collection frame 10. There is no need to manually remove the bent steel pipe from the pipe bending device, which is simple to operate and reduces labor intensity.

[0020] As a preferred embodiment, the fixing structure includes a fixing block 11 fixedly connected to the bottom plate 1, the end face of the fixing block 11 is flush with the tangent line of the groove 9 on the fixed disc 3 in the vertical direction, and the side of the moving disc 8 close to the ejection mechanism is fixedly connected to a mounting plate 12, and a first electric push rod 13 is fixedly connected to the mounting plate 12, and a moving block 14 is fixedly connected to the end of the first electric push rod 13. When fixing the pipe, the first electric push rod 13 is pushed outward, thereby driving the moving block 14 to move until the end face of the moving block 14 contacts the pipe and cooperates with the fixing block 11 to press and fix the pipe. After the bending is completed, the first electric push rod 13 is retracted.

[0021] As a preferred embodiment, a sawtooth groove is provided on one side opposite to the moving block 14 and the fixing block 11. The sawtooth groove is provided to increase the friction between the moving block 14 and the fixing block 11 so as to improve the fixing effect.

[0022] As a preferred embodiment, the push-out mechanism includes a vertical plate 16 fixedly connected to the bottom plate 1 through a connecting rod 15, a second electric push rod 17 is fixedly connected to one side of the vertical plate 16 close to the bottom plate 1, and a push rod 18 is fixedly connected to the end of the second electric push rod 17.

[0023] In order to adapt to pipes of different diameters, as a preferred embodiment, the crossbar 6 is composed of a hollow rod 19 and a solid rod 20, the solid rod 20 slides in the hollow rod 19, a number of corresponding positioning holes 21 are provided on the solid rod 20 and the hollow rod 19, and a positioning structure is provided between the solid rod 20 and the hollow rod 19. When it is necessary to adjust the distance between the fixed disk 3 and the movable disk 8 to adapt to pipes of different diameters, the position of the movable disk 8 is adjusted by adjusting the position of the solid rod 20, and then the solid rod 20 is fixed by the positioning structure and the positioning holes 21, so as to adjust the distance between the fixed disk 3 and the movable disk 8, thereby improving the practicality of the device.

[0024] As a preferred embodiment, the positioning structure includes a positioning sleeve 22 fixedly connected to the solid rod 20, a T-shaped positioning rod 23 is slidably connected inside the positioning sleeve 22, a spring 24 is fixedly connected between the T-shaped positioning rod 23 and the positioning sleeve 22, the spring 24 is sleeved on the outside of the T-shaped positioning rod 23, a pressing block 25 is fixedly connected to the upper side of the positioning rod 23, and the pressing block 25 passes through the positioning hole 21. When adjusting the position of the solid rod 20, the pressing block 25 is pressed downward so that the pressing block 25 is lowered into the hollow rod 19, at which time the spring 24 is in a compressed state, and then the solid rod 20 is moved. When the pressing block 25 moves to the next positioning hole 21, the spring 24 is no longer compressed, and the pressing block 25 pops out to the outside of the hollow rod 19 under the action of elastic potential energy. The above process can be repeated until the solid rod 20 is adjusted to the expected position.

[0025] In order to facilitate the overall movement of the device, as a preferred embodiment, a moving wheel 26 is provided below the support rod 2.
