Description

Electronic transformer core shaping device

technical field

Background technique

Since the iron core structure of electronic transformers mostly adopts a laminated structure, the air gap in the closed magnetic circuit formed by the iron core will lead to an increase in reluctance and magnetic flux leakage. The skewed iron core and irregular iron chips will also seriously affect the quality of the electronic transformer. Therefore, the shaping of the electronic transformer core is a key link to ensure the quality of the electronic transformer.

As a result, the operation is cumbersome and the work efficiency is low, which is not conducive to automatic production.
