How can the quality of silicon steel sheet transverse cutting line be improved?

The punching and shearing quality of silicon steel sheets during the processing of the transverse cutting line for silicon steel sheets, including punching size accuracy, geometric shape, burrs, degree of paint film damage, degree of bending and folding in the production process, etc., all directly affect the stacking coefficient, process coefficient, and gap between sheets. If the operation is improper and the quality control indicators cannot be achieved, it will increase the no-load current and no-load loss, and in severe cases, local overheating may occur. The punching and cutting quality of silicon steel sheets is very strict, therefore, the selection of transformer core transverse cutting wires with high requirements for various indicators is also very strict.
In order to meet the requirements of various quality indicators, the transverse cutting line of silicon steel sheets must achieve the following points:
1. The coil or sheet materials of the silicon steel sheet transverse cutting line should be stacked reasonably, and the handling and lifting should be handled gently to prevent scratches, knocks, bending or breakage;
2. The silicon steel sheet after transverse cutting line punching should be placed flat and neat, and the cutting edge should be sprayed with anti rust paint;
When the burrs on the transverse cutting line of silicon steel sheets are too high, the gaps between the cutting tools and molds should be adjusted in a timely manner, or the cutting tools and molds should be re ground or replaced. If the burrs on the already processed sheets are too large, they must be removed by pressing or using other hair removal equipment;
4. Individual bent pieces of the silicon steel sheet transverse cutting line must be leveled and cannot be transferred to the next process;
5. Straightness, radian and waviness of silicon steel sheet transverse cutting line sheet material shall be adjusted or removed during or before longitudinal cutting. It is impossible to correct these on processing equipment;
6. Carefully adjust all aspects of the processing equipment and molds to ensure that their dimensional accuracy and burrs are within the range specified by the quality standards;
7. When cutting silicon steel sheets, attention should be paid to the rolling direction;
8. During pre stacking, it is necessary to strictly select the films and pick out the unqualified ones;
9. The iron core structure and iron chips should be designed reasonably to facilitate automated punching, cutting, and stacking. Try not to use threaded holes as much as possible;
10. Advanced tools, molds, and production lines should be used as much as possible for production.
