The training will involve welding training of metal pipes of various materials. Training institutions need to process large quantities of pipeline test pieces for welders to practice and take exams.

[0004] However, the existing pipe cutting usually uses a handheld cutting gun for cutting, the cutting surface is not smooth, and the angle of the groove is not standard. If the pipe test piece is processed by machine tools, the price of machine tool processing is high, and the pipe mouth of the machine tool processed pipe test piece is not flat. Before the butt welding is required, manual grinding is required, which is not only time-consuming, but also increases the labor intensity of personnel. Therefore, it needs to be improved.

In addition, it is only necessary to pull the locking pin through the pull ring so that the locking pin is disengaged from the bottom of the buckle, thereby releasing the restriction on the buckle, and then the buckle is toggled to disengage it from the mounting strip to remove the magnetic track cutting main machine, and the operation is simple and convenient.

[0008] The beneficial effects of the utility model are as follows: by utilizing the magnetic track cutting main machine to drive the main shaft to rotate, the main shaft thereby drives the chuck at its end to rotate, so that after the steel pipe is clamped on the chuck, it can be synchronously rotated at a low and uniform speed, and then cut, and the cutting surface is smooth and the angle of the groove is standard; by arranging two mounting strips with positioning blocks on the side of the magnetic track cutting main machine, the magnetic track cutting main machine is mounted on the fixed plate through the mounting strips, and then limited by the buckles on the surface of the fixed plate, the disassembly and assembly of the magnetic track cutting main machine can be completed by controlling the clutch between the buckle and the mounting strip, and the operation is simple and convenient.
