[0031] Working principle:

[0032] The six bending plates 4 have different bending radii and can be used to bend pipes of different lengths. According to the actual bending requirement, the corresponding bending plate 4 is selected, the bending plate 4 is moved up and down by the lifting and rotating hydraulic host 21, and the bending plate 4 meeting the requirement is moved to a position at the same horizontal plane as the guide wheel 31. Then, the six different bending plates 4 are rotated, and the pipe locking buckle 5 on the side of the bending plate 4 meeting the requirement is rotated to a position opposite to the two guide wheels 31, so as to ensure that the pipe can be placed between the pipe locking buckle 5 and the pipe bending guide groove 41 through the guide wheel 31.

[0033] When the pipe is sent into the pipe locking buckle 5 and the pipe bending guide groove 41, the screw rod 54 is hinged on the hinge seat two 52 through the movable block 53, the screw rod 54 is flipped down and drives the outer pressing plate 55, the pressing plate 55 is aligned with the clamping groove 56, the screw rod 54 is rotated to drive the pressing plate 55 to move into the clamping groove 56, the pressing plate 55 is clamped into the clamping groove 56 and tightly presses the end of the pipe locking buckle 5, so that the pipe locking buckle 5 is tightly clamped on the end of the pipe, and the pipe is fixed to ensure that the pipe is stably bent in the pipe bending guide groove 41.

[0034] The lifting and rotating hydraulic host 21 is started to drive the bending plate 4 to rotate, and the pipe is bent by the pipe bending guide groove 41. While the bending plate 4 is rotating, the hydraulic telescopic rod 22 is used to push the bending plate 4 to move, so that the guide wheel 31 is always in contact with the side wall of the pipe, and the pressure of the guide wheel 31 and the pressure of the inner wall of the pipe bending guide groove 41 cooperate to tightly press the pipe into the pipe bending guide groove 41, so as to complete the bending operation of the pipe.
