Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a steel strand cutting device. Background Technology

[0002] Steel strand is a steel product made of multiple steel wires twisted around a central steel wire. These steel wires are usually made of high carbon steel and undergo special processing to achieve high strength and toughness. They are often used in concrete structures, building decoration, and power engineering. When using steel strand, it is necessary to select a suitable length of steel strand and cut it using a cutting device.

[0003] Existing cutting devices easily attract a large amount of sparks and iron filings when cutting steel strands, which can pollute the working environment. At the same time, the sparks generated during cutting may also cause fires, creating safety hazards. Since the coating material on the surface of the steel strands produces harmful gases during cutting, prolonged exposure can harm the health of workers. After searching, it was found that the technical solution provided by the utility model application with application number CN202120937415.7 also has the above-mentioned problems.
