Description
Technical Field
[0001] The utility model relates to the technical field of steel strip production, in particular to an automatic cutting device for hot-dip galvanized steel strips. Background Art
[0002] Hot-dip galvanized steel strip is a steel product that is made by coating a layer of zinc on the surface of cold-rolled or hot-rolled long steel plates through the hot-dip galvanizing process. This process can form a corrosion-resistant zinc layer on the surface of the steel strip, thereby improving its service life and corrosion resistance. At the same time, hot-dip galvanized steel strip is widely used in many fields due to its excellent performance, such as building materials, automotive parts, household appliances, industrial fields, etc.
[0003] In order to improve the efficiency of galvanizing and facilitate storage, the steel strip is in a coiled state during the two processes. The radius of the hollow circle inside the steel strip of different thickness will also be different when it is coiled. Traditionally, the steel strip is cut by lifting it onto a fixed frame by a machine, and then the device that binds the steel strip is manually untied, and finally the extended end of the steel strip is extended to the cutting equipment. Since the fixed frame needs to be replaced according to the different thicknesses of the steel strip, that is, the steel coils with different inner diameters, the entire production process is inefficient.
