Description

Technical Field

[0001] The utility model relates to the technical field of transformer core stacking, in particular to a transformer core stacking tool. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core. In electrical equipment and wireless circuits, transformers are often used to increase or decrease voltage, match impedance, and provide safety isolation. The transformer core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and coated with insulating paint. The iron core and the coil wound on it form a complete electromagnetic induction system. The power transmitted by the power transformer depends on the material and cross-sectional area of ​​the iron core. Therefore, in the manufacturing process of power transformers, the stacking of the iron core is a crucial link.

[0003] However, the positioning and clamping of the core pieces by the tooling are not precise enough, which can easily lead to deviations in the core stacking. In addition, the tooling lacks flexibility and cannot adapt to the requirements of core stacking of different specifications and sizes. For this reason, we propose a transformer core stacking tooling. Utility Model Content
