Description

Technical Field

[0001] The invention relates to the technical field of steel processing, in particular to a steel continuous groove edge grinding mechanism. Background Art

[0002] Steel is a material of a certain shape, size and performance made of steel ingots, billets or steel through pressure processing. Steel is an important type of metal plastic processing products. In the total output of steel, except for a small part formed by casting and powder metallurgy, most of it is made of steel through plastic processing. In addition to the specified chemical composition, good surface quality and precise geometric dimensions, steel also has sufficient mechanical properties such as tensile strength, yield strength, hardness, toughness, etc. Some have process properties such as weldability and easy forming, as well as some special physical and chemical properties (such as corrosion resistance, high temperature resistance, magnetic induction properties, etc.). According to the different cross-sectional shapes, steel can be divided into four categories: profiles, plates, pipes and metal products.

[0003] After the base is made of steel, multiple grooves need to be processed on the base to facilitate the processing of threaded holes. However, since the grooves on the base are arranged at intervals, after the base is formed, the edges of the grooves can only be polished by a manual handheld grinding mechanism, which is labor-intensive and inefficient. Summary of the invention
