The bottom end of the supporting rod 3 is fixed to the side plate of the V type groove 1 through detachable connection, which can adjust the position of the supporting rod 3 according to actual needs, the side of the supporting rod 3 facing the V type groove 1 is rotatably connected with the baffle 4, the bottom of the baffle 4 is designed in a conical shape to be able to be attached to the side wall of the V type groove 1, and the upper part of the baffle 4 is provided with the light blocking piece 5, the light blocking piece 5 is arranged opposite to the infrared proximity switch 6 when the baffle 4 is in a vertical state, forming a photoelectric detection system. When the pipe material enters the V type groove 1 and pushes the baffle 4 to rotate, the light blocking piece 5 will move accordingly, thereby changing the detection state of the infrared proximity switch 6, and this change will be converted into an electric signal and transmitted to the cutting piece 7 through the controller.

[0028] Between the discharge port of the pipe mill 2 and the V-shaped groove 1, a cutting device 7 is arranged, when the controller receives the signal from the infrared proximity switch 6, the pipe mill 2 stops working, the cutting device 7 will be started immediately to cut the pipe accurately, after cutting, the cut pipe in the V-shaped groove 1 can be transferred by the manipulator or manually by the operator.

[0029] The working principle of the cutting device of the pipe mill provided by the application is as follows: the pipe mill 2 starts to work, the pipe enters the V-shaped groove 1 from the discharge port, the pipe pushes the baffle 4 to rotate, drives the light blocking piece 5 to move, the infrared proximity switch 6 detects the position change of the light blocking piece 5 and transmits the signal to the controller.
