Description

Technical Field

[0001] The utility model relates to the technical field of transformer processing, and more specifically to a transformer core punching and shearing device. Background Art

[0002] The transformer core is the main magnetic circuit part of the transformer, usually made of hot-rolled or cold-rolled silicon steel sheets with high silicon content and coated with insulating paint. The iron core and the coil wound on it form a complete electromagnetic induction system, which is one of the most basic components of the transformer. The iron core is divided into two parts: the iron core column and the iron yoke. The winding is placed on the iron core column, and the iron yoke connects the iron core to form a closed magnetic circuit.

[0003] Shearing and punching the transformer core can improve the manufacturing quality of the core. Through the shearing and punching operation, the precise size and shape of the core can be ensured, thereby improving the performance and efficiency of the transformer; strengthening the magnetism of the cold-rolled silicon steel sheet. The transverse shearing in the shearing and punching operation can effectively strengthen the magnetism of the cold-rolled silicon steel sheet, which helps to improve the actual operating performance and final effect of the transformer equipment; reducing eddy current loss. Processing the core into sheets and insulating each other between sheets can reduce eddy current loss, reduce core heating, and improve the efficiency and service life of the transformer; adapting to the working requirements of the transformer: The transformer always works under AC state. The sheared and punched core can better adapt to this working state and ensure the stable operation of the transformer.

[0004] Although punching and shearing the transformer core has many beneficial effects, during the operation of punching and shearing the transformer core, due to the different numbers of transformer cores to be punched and sheared, the distance between the punching and shearing wheel and the transformer core is fixed, so a single operation is required, which reduces work efficiency.
