Pipe cutting device

The invention relates to the technical field of cutting equipment, in particular to a pipe cutting device. The pipe cutting device comprises a rail and a cutting machine, the cutting machine is arranged on the rail in a sliding mode, holding mechanisms used for holding pipes are arranged at a feeding port and a discharging port of the cutting machine, and first cleaning mechanisms are arranged at the holding mechanisms. The first cleaning mechanisms are used for cleaning sweeps on the holding mechanisms. The first cleaning mechanisms are used for cleaning the sweeps on the holding mechanisms, the sweeps are prevented from being retained on the holding mechanisms, so that the situation that the sweeps are clamped on the pipes when the pipes are held next time, and abrasion of the pipes is caused is avoided, and the quality of the pipes is guaranteed; and in addition, the machining environment is optimized by cleaning the sweeps of the holding mechanisms. 本发明涉及切割设备技术领域，具体为一种管材切割装置，包括轨道和切割机，切割机滑动设置在轨道上，切割机进料口和出料
