Description

Technical Field

[0001] The utility model relates to the technical field of steel strip processing, in particular to a steel strip shearing device. Background Art

[0002] Steel strips are cut from wide steel strips. To ensure the quality of the steel strips, the cut edge of the steel strips will form scrap steel strips after the wide steel strips are cut. In the case of continuous conveying of the steel strips, the scrap steel strips need to be collected. For example, the utility model patent with publication number CN219881428U is a longitudinal shearing machine based on steel strip processing and the invention patent with publication number CN115889878B is a shearing machine for producing steel strips and its production process.

[0003] In order to reduce costs and losses, the width of scrap steel strips is relatively narrow, and they are greatly affected by stress during cutting, resulting in deformation and distortion, and cannot be rolled up as neatly as finished steel strips. The rolled scrap steel strips have a large number of gaps due to deformation, resulting in excessive radial dimensions, which will affect the further rolling of the scrap steel strips and even interfere with the delivery of the finished steel strips. Increasing the axial dimension of the reel is conducive to suppressing the radial dimension of the scrap steel strip winding, but the scrap steel strip corresponds to a certain part of the reel and cannot be evenly wound on the outside of the axial parts of the reel.
