[0015] Example 1 Please see Figures 1 to 6 This utility model provides a technical solution: a metal pipe bending device, including a fixed handle 1, a base frame 2 fixedly connected to the bottom of the fixed handle 1, a rotating shaft 3 connected to the top of the base frame 2, a bending part 4 rotatably connected to the outside of the rotating shaft 3, a rotating handle 5 fixedly connected to one end of the bending part 4, a drive plate 11 placed at the bottom of the base frame 2, a guide groove 16 opened at the top of the drive plate 11, a piston chamber 22 opened inside the drive plate 11 and at one end of the guide groove 16, a piston block 23 slidably connected inside the piston chamber 22, a piston column 17 fixedly connected to one side of the piston block 23, one end of the piston column 17 extending into the guide groove 16 and fixedly connected to a drive column 18, a second pump 25 fixedly connected to one side of the drive plate 11, a first pump 24 fixedly connected to one side of the drive plate 11, one end of both the second pump 25 and the first pump 24 extending into the piston chamber 22, and a support plate 12 fixedly connected to the top of the drive plate 11 and below the fixed handle 1 and the rotating handle 5.
[0016] A liquid tank 26 is fixedly connected to one side of the drive plate 11 and to the right of the second pump 25. One end of the second pump 25 and the first pump 24 both extend into the liquid tank 26 to store hydraulic oil.
[0017] The bottom of the handle 5 is provided with a mounting groove 19, the top of the drive column 18 extends into the mounting groove 19, and a threaded groove 20 is provided on one side of the handle 5. A second screw 21 is threadedly connected inside the threaded groove 20. One end of the second screw 21 is inserted into the drive column 18, and the second screw 21 is unscrewed out from the mounting groove 19.
[0018] A second fixing block 14 is fixedly connected to the top of the drive plate 11. A first fixing block 13 is fixedly connected to one end of the fixing handle 1 and located behind the second fixing block 14. A first screw 15 is threadedly connected inside the second fixing block 14. One end of the first screw 15 extends into the first fixing block 13 and is threadedly connected to the inside of the first fixing block 13. By unscrewing one end of the first screw 15 from the inside of the first fixing block 13, the drive plate 11 can be moved down from the bottom of the base frame 2.
[0019] A fixed post 6 is fixedly connected to one side of the rotating handle 5. A rotating sleeve 7 is rotatably connected to the outside of the fixed post 6. A hook body 8 is fixedly connected to one end of the rotating sleeve 7. One end of the fixed post 6 extends to the outside of the rotating sleeve 7 and is fixedly connected to a screw 9. A nut 10 is threadedly connected to the outside of the screw 9. One end of the nut 10 abuts against one side of the rotating sleeve 7. By unscrewing the nut 10 from the outside of the screw 9, the rotating sleeve 7 and the hook body 8 are rotated to adjust the position of the hook body 8 so as to install the metal pipe and remove the bent metal pipe.
[0020] Example 2 Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 The present invention provides a technical solution: a controller 27 is fixedly connected to one side of the drive board 11, and a rechargeable power supply battery is fixedly connected to the controller 27. The device is powered by the rechargeable power supply battery and controlled by the controller 27. The device can also be powered directly.
[0021] In summary, when using this metal pipe bending device, the pipe is placed into the groove on one side of the fixed handle 1 and the groove on the other side of the bending part 4. Then, the hook 8 is hooked onto the outside of the metal pipe, and the nut 10 is tightened. The nut 10 holds one side of the rotating sleeve 7, thus fixing the position of the rotating sleeve 7 and the hook 8. Then, the rotating handle 5 is rotated towards the fixed handle 1, and the pipe is bent by the bending part 4 and the hook 8. The pipe is then removed from between the fixed handle 1 and the bending part 4. When long-term pipe bending is required, the drive plate 11 is placed under the base frame 2, one end of the first screw 15 is screwed into the first fixed block 13, the top end of the drive column 18 is inserted into the mounting groove 19, and one end of the second screw 21 is screwed into the drive column 18 to fix the rotating handle 5 and the drive column 18. Then, the hook 8 is hooked onto the outside of the metal pipe, and the controller 27 controls the second pump 25 to draw in the hydraulic oil from the liquid tank 26. Then, the hydraulic oil is input into the piston chamber 22 and located in the left chamber of the piston block 23 through the other end of the second pump 25. The hydraulic oil in the piston chamber 22 and located in the right chamber of the piston block 23 is extracted by the first pump 24. Then, the other end of the first pump 24 discharges the hydraulic oil into the liquid tank 26. This causes the piston block 23 to push the piston rod 17, the drive rod 18, the rotating handle 5, and the bending part 4 to rotate. This causes the bending part 4 and the hook body 8 to rotate, thereby bending the pipe. Remove the oil, and then the second pump 25 extracts the hydraulic oil from the piston chamber 22 and the left chamber of the piston block 23. Then, the hydraulic oil is discharged into the tank 26 through the other end of the second pump 25. Then, the first pump 24 extracts the hydraulic oil from the tank 26 and discharges it into the piston chamber 22 and the right chamber of the piston block 23. This causes the piston block 23 to drive the piston rod 17, the drive rod 18, the rotating handle 5, and the bending part 4 to return to their original rotation and continue the bending of the metal pipe.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
