Description

Technical Field

[0001] The invention relates to the technical field of sheet slitting, and in particular to a silicon steel sheet longitudinal shearing and slitting device. Background Art

[0002] The slitting of silicon steel sheets is to cut the cold-rolled silicon steel sheets into multiple strips according to certain specifications for subsequent processing and use. During the cutting process of the slitting machine, due to the uneven thickness and inconsistent hardness of the silicon steel sheets themselves, curling is easy to occur during the cutting process. At the same time, improper settings of parameters such as cutting speed, cutting depth, and cutting angle, or insufficient precision of the cutting equipment may cause curling of the silicon steel sheets during the cutting process. Maintaining high-precision cutting is difficult to achieve or costly in existing operations. Therefore, the slight curling is squeezed and restored by roller transmission. However, due to the wide pressing range, it is easy to cause the sheet on the side of the curling to cover the curling surface during pressing, causing local bulges at the edge. In addition, the cutting knife is prone to heat up during cutting, which causes damage during cutting. In addition, the cutting knife is prone to self-damage after debris adheres to the surface of the cutting knife. Summary of the invention
