Then the first chuck 21 moves towards the direction far away from the laser cutting device 50, the first chuck 21 is separated from the pipe, the second chuck 31 and the third chuck 41 clamp the pipe and move towards the direction far away from the laser cutting device 50, the second chuck 31 moves from the side of the laser cutting device 50 close to the first chuck 21 to the side close to the third chuck 41, and the port at one end of the pipe is positioned below the laser head. Then, on the premise of ensuring the length of the pipe, a small section is cut off from the port of the pipe through the laser cutting device 50, the port is made to be flush, and then the cut pipe is conveyed out.

This embodiment accomplishes the cutting work of tubular product jointly through first chuck 21, second chuck 31, third chuck 41, and the tubular product that tubular product port department cut off is less during the tubular product cutting, has realized zero tails basically, can not cause the waste of tubular product.

The embodiment of the present invention is not limited to this, according to the above-mentioned content of the present invention, the common technical knowledge and the conventional means in the field are utilized, without departing from the basic technical idea of the present invention, the present invention can also make other modifications, replacements or combinations in various forms, all falling within the protection scope of the present invention.
