Then, place one end of the pipe between the two sets of pipe clamps 8, and place the pipe body on the pipe rack 10. The pipe rack 10 supports the pipe body. Then, close the pneumatic clamp 7 to make the two sets of pipe clamps 8 clamp the pipe. Then, operate the control panel 18 to turn on the servo motor 3, and the servo motor 3 drives the movable shaft 4 to rotate. The movable shaft 4 drives the pulley assembly 5 to move.
