Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and more specifically, to a quick-change tool structure for silicon steel sheet slitting lines. Background Technology

[0002] A silicon steel sheet slitting line is a specialized piece of equipment for processing silicon steel sheets. It mainly consists of an uncoiler, a slitting machine, and a rewinder. The uncoiler unwinds the coiled silicon steel sheet, and the slitting machine uses multiple sets of blades to cut the sheet longitudinally to the required width. Then, the rewinder rewinds the cut silicon steel sheet back into coils. Silicon steel sheet slitting lines are characterized by high precision and high efficiency, and can meet the processing needs of silicon steel sheets of different specifications. They are widely used in the manufacturing industries of electrical equipment such as motors and transformers, providing an important processing method for producing high-quality silicon steel sheet components.

When a blade is damaged, it is difficult to replace it quickly. Furthermore, the spacing between the multiple sets of blades cannot be adjusted, which cannot meet the processing requirements of silicon steel sheets of different specifications, thus reducing the flexibility and adaptability of production.
