Description

Technical Field

[0001] The utility model relates to the field of mechanical cutting, in particular to an automatic equidistant cutting structure for steel pipes. Background Art

[0002] Steel pipes can be categorized by material type, including carbon structural steel, low-alloy structural steel, alloy steel, and composite steel. By application, they can be divided into pipes for transportation, engineering structures, thermal equipment, the petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment. Steel pipes are a key construction material and typically require cutting according to specific requirements. This process requires the use of a cutting machine. The operator pre-marks the required length on the steel pipe, then moves the pipe under the cutting machine, which cuts the pipe along the pre-marked line. The remaining pipe is then returned to the cutting machine for further cutting.

[0003] The entire cutting process is inseparable from the operator's handling and pushing operations. Manual handling and operation have low work efficiency, high labor costs and high labor intensity. Manual handling will also cause the main steel pipe to be unstable and prone to shaking, and it is easy to cut crookedly or have cutting burrs at the cutting point.

[0004] Therefore, it is necessary to design an automated mechanical structure that is easier to cut steel pipes and improves work efficiency. While significantly improving the cutting efficiency of steel pipes, it also ensures the pass rate of single steel pipes after cutting, which is feasible for market promotion. Utility Model Content
