[0038] The stepper motor 2 52 pushes the clamping block 2 49 to clamp the pipe. The pipe is located in the arc groove 51. The arc groove 51 positions the pipe for cutting. The motor 8 drives the cutting blade 9 to rotate. The cylinder 1 3 pushes the cutting blade 9 to cut the pipe. The cut pipe is collected into the collection frame through the blanking plate 10. At the same time, the sorting mechanism 11 on the blanking plate 10 automatically sorts the short tail materials that do not meet the length requirements.
