Silicon Steel Cut To Length Line JY-400
Double Shear Double Punch Transformer Core Cutting Machine
6
The JY-400 Double Shear Double Punch Cut to Length Line is a fully automatic transformer core lamination production system designed for high-precision processing of silicon steel coils. This advanced machine integrates feeding, punching, V-notching, shearing, sorting, and stacking into one continuous workflow, ensuring high efficiency and consistent product quality.
It is widely used for manufacturing step-lap transformer cores, EI laminations, and mitered core sheets in power and distribution transformer industries.
Product Description
This silicon steel processing line converts electrical steel coils into accurately cut transformer laminations with different joint types, including:
Full miter joints
Half miter joints
Straight joints
With its double shear + double punch structure, the JY-400 ensures stable operation, reduced burr, and improved magnetic performance of transformer cores.
