JY-400 Double Shear Three Punch Cut-to-Length Line (Reverse Stacking Type)
High-Efficiency Transformer Core Lamination Production Line
The JY-400 Double Shear Three Punch Cut-to-Length Line (Reverse Stacking Type) is a fully automatic production system designed for high-precision processing of grain-oriented silicon steel coils into transformer core laminations.
This advanced machine integrates feeding, dual V-notching, hole punching, shearing, automatic sorting, and reverse stacking (magnetic suction system) into one continuous production line, significantly improving efficiency and stacking accuracy.
It is widely used for producing step-lap transformer cores, EI laminations, and mitered core sheets for medium and large transformer manufacturers.
Product Overview
This reverse stacking silicon steel cut-to-length line is specially designed to:
Process electrical steel coils into precise transformer laminations
Support full miter, half miter, and straight joint designs
Improve stacking quality through automatic magnetic reverse stacking
Compared with traditional lines, this machine provides higher automation, better stacking accuracy, and reduced manual handling.
Key Features
Double Shear + Three Punch Advanced Structure
2 × V-notch punching units
1 × hole punching unit
2 × angle shearing units (45° & 135°)
This design enables multi-step processing in a single cycle, improving production efficiency.
Reverse Stacking System (Core Advantage)
Magnetic suction stacking system
Automatic sorting and layering
Improved stacking alignment accuracy (±5 mm)
Reduced manual labor and errors
This is especially suitable for high-end transformer core production.
High Precision Servo Control
