If the material 8 is a tubular product with a circular structure, the steering cylinder I rotates the centering bracket 412-21 to an upward position, the fourth lifting cylinder drives the clamping centering unit 412-3 to fall until the tubular product falls into a centering notch of the centering bracket 412-21 to realize centering, and the third lifting cylinder lifts the lifting base station I412-2 until the axis of the tubular product is superposed with the central lines of the three chuck mechanisms.

If the material 8 is in a non-circular structure, the centering cylinder drives the two centering clamping jaws to clamp the material 8, the material 8 is centered to the middle position of the two clamping jaws, the steering cylinder I rotates the clamping support brackets 412-22 to the upward position, the fourth lifting cylinder drives the clamping centering unit 412-3 to fall until the material 8 falls on the clamping support brackets 412-22, and the third lifting cylinder lifts the lifting base station I412-2 and simultaneously clamps the support brackets 412-22 to lift the material 8 until the central line of the material 8 is coincident with the central lines of the three chuck mechanisms.

Back chuck mechanism 31 moves along chuck guide rail 11, and the one end of material 8 is by back chuck mechanism 31 chucking, and back chuck mechanism 31 promotes material 8 forward motion to the light curtain position that the other end of material 8 penetrated well chuck mechanism 32, and the system can automatic identification material 8 front end position this moment, judges pipe fitting length from this and carries out flush cutting according to this parameter.

And (3) treating the flush cutting waste: the output end of a turning plate cylinder of the short material collecting device 7 extends to push a lower turning plate 723 to be flush with a flat supporting plate 721, a middle chuck mechanism 32 moves to the position of the end of the lower turning plate 723 along a chuck guide rail 11, and a lifting base station III moves to the lower side of the waste along a second distance adjusting slide rail along a second sliding seat to receive the waste.

The inclined part of the third base frame 711 helps the short material to continuously slide for a certain distance, which is beneficial to automatically adjusting the direction of the short material to be parallel to the y-axis direction in the continuous sliding process so as to fall into the short material through opening 711-1. The shorter the cut material 8 is, the more the material 8 tends to be close to the laser pipe cutting device 2 when falling, and meanwhile, the shorter the length of the material 8 is, the more the material 8 is easy to deviate from the y-axis direction in the sliding process, so that the deviation rectifying baffle 711-3 is arranged at the corresponding side end of the third storage pedestal frame, and the situation that the shorter material 8 slides out of the short material storage mechanism 71 from the side end of the third storage pedestal frame can be prevented.

For the collection of long lengths greater than 1.5m after cutting: when the material 8 is a tubular product with a circular structure, the reversing cylinder II rotates the blanking carrier roller frame to enable the first carrier roller group to face upwards; when the material 8 is in a non-circular structure, the steering cylinder II rotates the blanking carrier roller frame to enable the second carrier roller group to face upwards.
