[0002] When the pipe is in use, a bending machine is needed to bend the pipe into different shapes to adapt to different work requirements.

[0003] A Chinese patent discloses a pipe bending machine with a publication number of CN115921620A, which includes a pipe centerline translation adjustment mechanism and a wheel cleaning mechanism. The invention measures the horizontal distance from the leftmost end of the pipe to the center of the wheel through the pipe centerline translation adjustment mechanism, inputs the length difference between the distance and half the length of the pipe into the PLC touch screen, and moves the pipe until the horizontal distance from the leftmost end of the pipe to the center of the wheel is half the length of the pipe, thereby ensuring that the lengths of both sides of the pipe are the same when the pipe starts to bend, and the symmetry of the bending parts on both sides of the U-shaped pipe is maintained; through the wheel cleaning mechanism, the cleaning bottom plate is pushed, so that the cleaning film and the cleaning brush contact and squeeze the inner side of the wheel, and the dirt remaining on the inner side of the wheel is cleaned, so as to avoid the accumulation of impurities such as rust and dust on the inner side of the wheel after the wheel is used for a long time, forming small protrusions, which are easy to cause deformation and damage of the pipe when bending, and has the characteristics of strong practicality.

[0004] However, there are still the following disadvantages: when the device bends the pipe, the wheel group is used to apply force to the pipe to bend the pipe, but the wheel group has poor wrapping performance on the pipe, which easily causes the pipe that needs to be kept straight to be bent, and the practicality is poor.
