Revolutionize your sheet metal production with the DF Series Coil-Fed Laser Cutting Line. By processing directly from raw metal coils, this fully automated system eliminates the premium cost of pre-cut sheets and drastically reduces material waste. Integrating a heavy-duty decoiler, an advanced 11-roller precision leveler, and a high-speed fiber laser cutter into one continuous workflow, it minimizes manual handling and guarantees highly profitable, uninterrupted manufacturing.
The DF Series is an advanced flexible production line integrating a decoiler, leveler, feeder, and fiber laser cutting system. Controlled by a dedicated CNC and PLC system, it achieves fully automated continuous processing from coiled metal strips to finished cut parts and scrap disposal, significantly boosting production efficiency.
The robust decoiler features a hydraulic expansion spindle accommodating coil inner diameters of Φ470-Φ530mm and weights up to 10 tons. Driven by a variable-frequency motor, it includes a pneumatic disc brake and a hydraulic press arm, ensuring smooth unwinding without material rebound.
Utilizes a highly precise 11-roll leveling structure (5 upper, 6 lower) made of heat-treated Gcr15 material. Driven by a 5.5KW Inovance servo motor and precision gears, it effectively eliminates material wrinkles and feeds the sheet into the laser zone with an exceptional length accuracy of ±0.5mm/m and flatness ≤±1.5mm/m².
Incorporates a reliable Omron photoelectric loop control system beneath the press arm. It constantly monitors the material loop droop and dynamically feeds back signals to control the decoiler's start and stop, maintaining a perfect tension-free buffer loop before entering the leveling machine.
The main machine structure boasts a steel-welded bed for extreme rigidity and an extruded aviation aluminum gantry for lightweight, high-acceleration dynamics (up to 1.5G). Driven by DELTA servo motors and guided by AirTAC/ROUSTWORLD linear rails, it achieves an X/Y positioning accuracy of ±0.03mm/m.
