PE pipeline cutting device with anti-deformation function

The invention discloses a PE pipeline cutting device with an anti-deformation function, and relates to the technical field of pipeline machining. A PE pipeline cutting device with an anti-deformation function comprises a machine tool, the machine tool is fixedly connected with supporting frames distributed in a mirror image mode, a cross beam is slidably connected between the supporting frames distributed in the mirror image mode, a hydraulic push rod is installed on the cross beam, the cross beam is fixedly connected with a second sleeve, and the second sleeve is slidably connected with a first push rod. A driving device is installed at the lower end of the first push rod, a cutting blade is installed on the driving device of the first push rod, and the cutting blade is matched with the pipe. By controlling the downward moving distance of the cutting blade every time, the cutting depth of the cutting blade on the pipe is controlled, and by gradually increasing the cutting depth on the pipe, the situation tha
