The DHJ400 Automatic Core Cutting Machine is a high-efficiency precision solution specifically designed for shearing silicon steel strips used in reactor core manufacturing. Capable of processing strip widths up to 400mm, this advanced equipment integrates seamless cutting and optional hole-punching into a single automated workflow. Powered by high-performance servo motors, it guarantees exceptional cutting accuracy and operational stability, making it an ideal choice for power equipment manufacturers.
High-Precision Servo Drive: Equipped with a premium servo motor system for driving both cutting and punching operations, ensuring unmatched dimensional tolerance.
Ultra-Durable Tooling: The cutter and shearing blades are crafted from premium carbide alloy with a hardness of HRC 88 ~ 90. They deliver an impressive lifespan of over 5 million cuts before requiring regrinding, drastically reducing maintenance downtime.
User-Friendly Interface: Features an intuitive touchscreen control panel (HMI) that simplifies setup, parameter adjustments, and daily operation.
Integrated Punching Unit: Supports online hole punching during the shearing process to meet diverse reactor core design requirements.
The RHJ-400 silicon steel cutting line consists of the following 7 core modules:
Hydraulic Decoiler: For stable and efficient steel coil loading.
Machine Base Frame: Heavy-duty main body for vibration-free operation.
Sheet Feeding Unit: High-speed, precision material feeding.
Hole Punching Device: Automated online punching system.
Shearing Unit: High-hardness carbide alloy cutting assembly.
Stacking Table: For neat collection and alignment of finished sheets.
Central Control System: Intelligent PLC and touchscreen operation interface.
