The second chuck mechanism 30 then grips the tubing and cuts it through the laser cutting head.

In order not to hinder the movement of the first chuck mechanism 20 when the first chuck mechanism 20 moves close to one of the follow-up feed mechanisms 90 during the movement of the running pipe, the follow-up feed mechanism 90 is retracted to one end of the first conveying mechanism 80. In the process of cutting the pipe, the follow-up feeding mechanism 90 is used for supporting the pipe and preventing the pipe from sagging. The cut pipe is a square pipe or a round pipe, and when the first chuck mechanism 20 and the second chuck mechanism 30 drive the square pipe to rotate, the second jacking component 95 of the follow-up feeding mechanism 90 can drive the supporting component to move up and down along with the movement of the pipe.

When one end of the pipe is cut, the second moving mechanism 120 drives the third chuck mechanism 40 to move toward the second chuck mechanism 30, and clamps the other end of the pipe. Then the second chuck mechanism 30 releases the tube, the third chuck mechanism 40 drives the tube to move away from the second chuck mechanism 30, and one end of the tube is separated from the first chuck mechanism 20.

When one end of the pipe also needs to be cut, one end of the pipe can be positioned on the second chuck mechanism 30 and clamped, and the pipe is cut by the laser cutting head. After the cutting is completed, the third chuck mechanism 40 continues to drive the pipe to move in a direction away from the second chuck mechanism 30. Finally, the tube is taken down from the third chuck mechanism 40 by the tube blanking and conveying device 70 and conveyed out.

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.
