The ZJX1250 Automatic Core Slitting Machine is a heavy-duty, professional solution engineered for the high-precision longitudinal cutting of silicon steel sheets.
This high-performance slitting line is primarily utilized to process wide silicon steel coils into multi-blank strips of varying widths. These precision-slit strips are essential raw materials for manufacturing transformer core components, including outer legs, center legs, upper yokes, and lower yokes. Featuring advanced automation and a user-friendly interface, the ZJX1250 significantly boosts production efficiency while ensuring flawless edge quality.
High-Efficiency Multi-Slitting: Equipped with 6 sets of premium cutters as standard, the system can slit up to 5 strips simultaneously in a single pass.
Scalable and Flexible Tooling: The number of cutters can be easily increased or adjusted upon request to produce narrower strips and accommodate diverse production needs.
Variable Speed Control: The slitting speed is fully adjustable, allowing operators to optimize throughput based on material thickness and operational requirements.
Superior Edge Quality: Delivers clean cuts with a minimal burr height of ≤0.02 mm, preserving the magnetic properties of the silicon steel.
Robust Automation: Engineered for high automation, minimizing manual labor from coil loading to final rewinding, ensuring maximum safety and uptime.
The ZJX1250 silicon steel slitting line integrates 8 heavy-duty modules for a seamless workflow:
Loading & Unloading Coil Car (Trolley): For safe and efficient heavy coil handling.
Decoiler (Uncoiler): Securely holds and feeds the master steel coils.
Material Receiver Platform: Ensures smooth initial guiding of the sheet.
Movable Guide Device: Aligns the sheet precisely before entering the slitting head.
Precision Slitting Device: High-accuracy cutter shaft assembly for precise strip widths.
Recoiler / Winder: Tightly recoils the slit strips into neat, individual coils.
Hydraulic Station & Pneumatic System: Provides powerful and stable pressure for heavy-duty operations.
Electrical Control Cabinet & Operator Console: Centralized PLC system for seamless line synchronization.
