Description

Technical Field

[0001] The utility model belongs to the technical field of cold-rolled steel strip trimming, in particular to a cold-rolled steel strip fixed trimming device. Background Art

[0002] Cold-rolled steel strip is made from hot-rolled coil, rolled at room temperature below the recrystallization temperature. It comes in both plates and coils and is produced by numerous domestic steel mills, including Baosteel, Wuhan Iron and Steel, and Anshan Iron and Steel. Steel delivered in sheets is called steel plate, also known as box plate or flat plate; steel delivered in long coils is called steel strip, also known as coil.

[0003] Most of the existing cold-rolled steel strip trimming equipment requires the cold-rolled steel strip to be unfolded before trimming. Although this is convenient, since the cold-rolled steel strip coil is made of many layers of steel strip, the processing efficiency will be reduced after the cold-rolled steel strip coil is unfolded and trimmed, which greatly reduces the scope of application of fixed trimming equipment.
