Description

Technical Field

[0001] The utility model relates to the technical field of acid continuous rolling steel plate shearing, in particular to an acid continuous rolling disc shearing device. Background Art

[0002] The acid continuous rolling disc shear device is mainly used in the metal processing industry, especially in the steel production process, for cutting and trimming the continuously rolled steel. The current disc shear device generally includes two disc groups arranged on both sides of the steel plate, and each disc group includes two upper and lower discs. The two discs are staggered, and the two discs shear the steel plate when the steel plate passes. Since the trimming of the steel plate needs to be carried out continuously, the discs wear out quickly, especially the replacement cycle of the upper disc is very short. However, there is an overlapping part between the two discs in the normal direction, and the distance between the two discs is relatively close, so the upper disc cannot be directly removed. The lower disc can only be removed, and then the upper disc can be removed for replacement. The disc is generally fixed by a circle of multiple bolts, which is troublesome to disassemble.
