Steel Coil Cutting Machine

Shijiazhuang Faith Machinery Co.,Ltd offers a robust Steel Coil Cutting Machine designed to slice heavy-gauge steel strip from large coils into precise lengths for downstream fabrication processes. This machine addresses the needs of steel service centers, heavy machinery manufacturers, and construction component producers by combining stable mechanical design with user-friendly controls.

Core Components and Workflow

1. Coil Handling and Decoiling

• Hydraulic mandrel decoilers clamp and expand within the coil ID, supporting weights up to 25 tons.

• An automatic coil car positions each coil under the shear unit, minimizing manual intervention and improving safety.

2. Strip Tensioning and Leveling

• Entry pinch rolls pull the strip from the decoiler into a tension-leveling section.

• A multi-bar leveler straightens residual coil set and ensures uniform strip flatness before cutting.

3. Shearing Mechanism

• The core shear features upper and lower blades mounted on guides hardened for wear resistance.

• Hydraulic or pneumatic cylinders drive the shear, providing consistent cutting force across thicknesses from 1 mm to 12 mm.

4. Cut-to-Length Accuracy

• A servo-driven feed table measures strip advance with an encoder, achieving length tolerances within ±1 mm.

• Flying shear configurations allow continuous cutting at line speeds up to 60 m/min, reducing downtime for long production runs.

5. Material Discharge

• Cut sheets are discharged onto adjustable conveyors or stacking tables.

• Optional stacking robots or automated trolleys organize sheets by size and thickness for efficient handling.

Control and Safety Features

• Central PLC Control: Operators set cut lengths, material thickness, and line speed via an HMI touchscreen. Recipes can be saved for repeat jobs.

• Safety Interlocks: Guarding around the shear and pinch rolls prevents access while the machine is running. Emergency-stop buttons are positioned at key locations.

• Diagnostics and Logging: The control system logs cycle counts, material thickness changes, and any fault codes for maintenance planning.

Customization and Services

• Blade Materials: Available in tool steel, carbide-tipped, or coated options to match specific strip materials.

• Cutting Modes: Choices of single-cut, flying (in-motion) cut, and bundle-cut modes depending on production requirements.

• After-Sales Support: Faith Machinery provides commissioning assistance, operator training, preventive maintenance schedules, and spare parts kits to ensure sustained productivity.
