Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled steel strip cutting, in particular to a cold-rolled steel strip cutting device. Background Technique

[0002] The cold-rolled steel strip is made from hot-rolled coils and rolled at room temperature below the recrystallization temperature, including plates and coils. Many domestic steel mills such as Baosteel, Wugang, and Angang can produce it. Those with a long length and delivered in coils are called steel strips. The production of steel coils requires a cutting device to be connected after the cold rolling line.

[0003] In the cold-rolled steel strip cutting device used in the prior art, the cutting knives on its outer side are manually arranged by workers on the outer side of the driving roller. Therefore, when the cutting width requirement of the cold-rolled steel strip changes, it is necessary to stop the machine, remove the cutting knives and re-arrange them to adjust the spacing between the cutting knives. Since adjusting the spacing between the cutting knives requires removing the cutting knives and re-arranging them, the adjustment efficiency of the spacing of the cold-rolled steel strip cutting knives is low. For this reason, we propose a cold-rolled steel strip cutting device. Content of the Utility Model
