In automotive seat frame production, decoiler machines deliver essential material handling for high-speed stamping lines. Utilizing a motor-driven reducer system, the decoiler rotates its spindle to unwind coiled steel, ensuring seamless feeding into presses. To adapt to material thickness variations and production demands, key accessories enhance performance:
-
Pneumatic Pressure Arm
Securely clamps steel coils after strap removal, preventing material spread during uncoiling. Its auto-rotating rollers synchronize with coil speed, eliminating slippage and surface scratches—critical for defect-free seat frame blanks. -
Guide Arm System
Positioned at the machine’s upper-right side, guide wheels align with coil edges to prevent lateral deviation during uncoiling. Operated pneumatically, the outer wheel adjusts vertically (manual control via HMI), while the inner wheel adapts to coil width. Note: Outer wheels must retract before auto-operation. -
Support Arm
Lifts material for effortless transfer to levelers. Pneumatically controlled, it simplifies threading and protects operators. Auto-mode requires the arm in the lowered position. -
Inverter Control
MT-series decoilers use inverters for dynamic speed adjustment. “Control” signals set motor speed; “regulation” uses real-time feedback to maintain precision. For seat frame stamping:-
Surface Integrity: Inverters prevent material scratches on critical structural parts.
-
Efficiency: Synchronizes with presses, reducing idle time by 15–20%.
-
Durability: Extends motor and electrical system lifespan by minimizing abrupt starts/stops.
