[0026] Support seat 4 is provided with two, two support seats 4 are symmetrically distributed on the two sides of the middle line of the top rear end of box 1.

[0027] Chain wheel one 42 and chain wheel two 43 are located in the same plane, chain wheel one 42 and chain wheel two 43 are linked through a chain.

[0028] The bending assembly comprises a telescopic hydraulic assisting device 3 arranged at the top rear end of the lifting rotary hydraulic host 21, the end of the push rod of the telescopic hydraulic assisting device 3 is fixed with a U-shaped frame 31, and the U-shaped frame 31 is rotationally arranged with a bending pressing wheel 32.

[0029] The bending pressing wheel 32 is located at the middle line position between the two support seats 4, and the bending pressing wheel 32 and the two guide wheels 41 are located in the same plane.

[0030] Working principle:

[0031] When the pipe loading operation is performed, the operator sends the pipe between the bending pressing wheel 32 and the guide wheel 41. Then, the driving motor 44 is started, and after the motor operates, the sprocket 43 starts to rotate under the driving of the sprocket 43. The sprocket 43 is connected with the sprocket 42 through the chain, and the sprocket 42 rotates synchronously under the transmission of the chain, and then drives the guide wheel 41 to rotate. With the continuous rotation of the guide wheel 41, the pipe moves stably along the rotation direction of the guide wheel 41 to the preset position required for bending.

[0032] When the pipe loading operation is performed, the operator sends the pipe between the bending pressing wheel 32 and the guide wheel 41. Then, the driving motor 44 is started, and after the motor operates, the sprocket 43 starts to rotate under the driving of the sprocket 43. The sprocket 43 is connected with the sprocket 42 through the chain, and the sprocket 42 rotates synchronously under the transmission of the chain, and then drives the guide wheel 41 to rotate. With the continuous rotation of the guide wheel 41, the pipe moves stably along the rotation direction of the guide wheel 41 to the preset position required for bending.

[0033] After the pipe is pushed to the predetermined bending angle by the bending pressing wheel 32, the lifting rotary hydraulic host 21 starts to work and drives the bending assembly to rotate slowly. At the same time, the telescopic hydraulic assisting device 3 also acts synchronously and drives the bending pressing wheel 32 to retreat and move stably along the side wall of the pipe. In the moving process, the bending pressing wheel 32 continuously rolls the side wall of the bent pipe again, so that the bent pipe can obtain more ideal bending effect, and the shape of the bent pipe is more in line with the process requirements.

[0034] After the pipe completes the whole bending process, the hydraulic telescopic rod 22 is started, which drives the machine box 2 to retreat backward. With the movement of the machine box 2, the bending pressing wheel 32 is smoothly removed from the side wall of the pipe, and the bending operation of the pipe is completed; when the machine box 2 moves, the guide rail 23 slides on the sliding block 24, and the movement of the machine box 2 is guided by the guide rail 23 and the sliding block 24, so that the stability of the movement is improved, and the telescopic hydraulic assisting device 3 drives the U-shaped frame 31 and the bending pressing wheel 32 to retreat.
