The sawing machine for processing steel pipes includes a sawing machine body, on which two lifting components arranged in mirror image are arranged, and the lifting components slide up and down on the sawing machine body with a single degree of freedom, and the lifting components are provided with a clamping device, and the sawing machine body is provided with a driving component for driving the lifting components to move up and down; a steel pipe is placed on the sawing machine body, and when the diameter of the steel pipe is large, the center of the steel pipe is far away from the bottom of the sawing machine body, so the maximum diameter of the steel pipe is relatively far away from the bottom of the sawing machine body. At this time, the lifting component is driven to move upward by the driving component, so that the lifting component drives the clamping device to move upward, so that the clamping device can clamp the maximum diameter of the steel pipe to a suitable position, and then the clamping device is operated to clamp the steel pipe. The above-mentioned prior art has certain limitations when in use. It can only adjust steel pipes of different diameters, and the clamp cannot clamp multiple steel pipes at the same time. Therefore, in actual use, a single steel pipe is clamped and sawed at a time, which reduces the flexibility of use and leads to a decrease in the sawing efficiency of the steel pipe. In summary, corresponding improvements are needed. Utility Model Content
