According to the silicon steel sheet iron core production line, the equipment automation degree can be improved, the lamination speed is increased, and thus the production efficiency of the production line is improved.

Description

technical field [0001] The invention relates to the field of transformer iron core production equipment, in particular to a silicon steel sheet iron core production line. Background technique [0002] With the development of science and technology, people's dependence on electricity continues to increase, and the demand for electricity continues to increase. As the key equipment in the power transmission work, the market demand of the transformer is also increasing. The iron core is the most critical part of the transformer, and the quality of the iron core plays a decisive role in the performance of the transformer. [0003] Most of the existing iron cores are made by stacking a certain number of silicon steel sheets, and the stacking of silicon steel sheets is a very high-end manufacturing process. The silicon steel sheet is generally only 0.27 mm thick. An ordinary ultra-high voltage transformer generally needs to stack more than 32,000 silicon steel sheets, and the pos...

AI Technical Summary

Problems solved by technology

Due to the huge number of laminations and the very high requirements for lamination accuracy, the increase in lamination speed is greatly limited, resulting in a long production cycle of the iron core, huge power consumption, and the failure of the entire iron core due to the drop of the silicon steel sheet due to power failure. phenomenon, which further reduces the generation efficiency

[0004] In addition, the structure of the iron core is various, such as single-phase three-column, single-phase four-column, three-phase three-column, three-phase five-column, etc. Silicon steel coils need to be cut horizontally and vertically, and multi-directional stacking is required , which further increases the difficulty of core stacking and limits the improvement of lamination speed

[0005] At present, most of the silicon steel sheet core production lines on the market need to be completed by manual or semi-automatic production lines. The lamination speed limits the shearing speed, resulting in low production efficiency of the entire production line, which cannot meet the growing market demand.
