Description

Technical Field

[0001] The present application relates to the field of steel processing equipment, and in particular to a steel coil shearing flying shear unit. Background Art

[0002] Steel coil shearing flying shear units are widely used in the steel processing industry. They are mainly responsible for cutting continuously produced steel coils into required sizes. With the improvement of industrial automation, the requirements for production efficiency and precision of this equipment are also getting higher and higher.

[0003] Existing steel coil shearing flying shear units usually adopt a variety of technical means to achieve efficient shearing operations. For example, some systems use fixed upper and lower scissors for shearing, and complete the shearing action through hydraulic or pneumatic drive; other systems use adjustable floating scissors, which can flexibly adjust the shearing position on steel plates of different thicknesses; in addition, some designs use multi-stage linkage mechanisms to ensure the stability and shearing quality of the steel plates during the shearing process.

[0004] Although the above-mentioned traditional technology can basically meet the basic needs of steel coil shearing, there are still many shortcomings in practical applications. In particular, during the shearing process, it is often necessary to stop the conveying action of the steel plate and then use the shearing mechanism to shear the plate. The shearing of steel plates larger than the next batch may not have a great impact, but in a large number of continuous shearing, this operation process greatly reduces the shearing efficiency. When continuous shearing is performed using a shear roller, the shearing point of the shearing piece will change as it rotates, resulting in the problem of uneven shearing of the thick plate. Therefore, how to improve the shearing mechanism so that it can have high shearing quality while ensuring high efficiency for steel coils of different specifications. Summary of the invention
