[0001] The utility model relates to the technical field of pipeline cutting devices, in particular to a pipeline production cutting device with a fixed structure. Background Art

[0002] Pipe cutting machine is a kind of cutting tool mainly used for cutting pipes and cylindrical objects. Pipe cutting machine is widely used and can easily cut pipes. When cutting round pipes, they need to be clamped and fixed before cutting.

[0003] The Chinese patent "A Pipe Cutting Device" authorization announcement number "CN113441961B" uses the interaction of fixed clamps, sliding clamps, and elastic airbags to clamp and fix the pipe before cutting, making it less likely for the pipe to deviate or shake during cutting, without the need for repeated adjustments, thereby improving work efficiency;

[0004] However, the clamping force is not easy to control during the early positioning. If it is too large, it will easily damage the pipe surface, and if it is too small, the clamping will not be in place. At the same time, during the cutting process, the pipe will vibrate, which will affect the clamping force. It cannot be adjusted during the cutting process, affecting the stability of the clamping.

[0005] Therefore, a cutting device for pipe production with a fixed structure is proposed to solve the above problems. Utility Model Content
