The upper pressure roller on the left side can be a rubber roller to avoid crushing the steel pipe. After the steel pipe is clamped, there are multiple steel pipes distributed front and back and separated by the partition 15 between the support plate 13 and the cover plate 14. Then the No. 1 motor is energized and all the steel pipes are driven to the right for a certain distance, and then the cutting work is carried out;

[0036] At this time, the No. 1 motor is powered off and locks the left and right positions of the steel pipe. Then, the No. 2 cylinder 21 drives the saw table 12 to sink while the saw blade 16 is rotating. During this process, the saw table 12 will saw off the steel pipe extending to the right side of the support plate 13 and the cover plate 14, and the fallen steel pipe will roll down to the lower right along the roller, and the steel pipe cutting work is completed.

[0037] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
