Technical Field
[0001] The invention relates to the technical field of flat steel bending of a pulley block base, and in particular to a flat steel bending device for a pulley block base. Background Art
[0002] Flat steel is a type of steel with a width ranging from 12-300mm and a thickness of 3-60mm. It has a rectangular cross-section and slightly blunt edges. Based on the material, flat steel can be divided into two categories: carbon flat steel and alloy flat steel. Alloy flat steel is made by adding one or more alloying elements to carbon steel. The addition of these elements significantly improves key properties such as strength, hardness, wear resistance, and corrosion resistance. For this reason, alloy flat steel is often used in the manufacture of components requiring high strength and special properties, such as automotive shaft components and pulley bases.
