Thermal insulation pipe shearing device

The utility model provides a thermal insulation pipe shearing device and relates to the technical field of thermal insulation pipe shearing, the device comprises a base mechanism, a cutting mechanism and a fixing mechanism, the base mechanism comprises a machining table top, the lower surface of the machining table top is fixedly connected with a supporting frame, the cutting mechanism is used for shearing a thermal insulation pipe, the cutting mechanism is arranged in the machining table top, and the fixing mechanism is used for fixing the thermal insulation pipe. Compared with the prior art, the thermal insulation pipe cutting device has the advantages that the first cutting gear and the second cutting gear are controlled to move through the first hydraulic telescopic rod, and meanwhile, the two sides of the cutting position of the thermal insulation pipe are fixed through the fixing mechanism, so that the effect of stably cutting the thermal insulation pipe is achieved; and meanwhile, a lower pressing bloc
