1. Equipment Structure and Components**
Uncoiler**: Holds metal coils (e.g., galvanized steel, color-coated steel, aluminum-magnesium-manganese alloy) and automatically unwinds and feeds the material into the forming system.
Roll Forming Unit: Composed of multiple sets of precision rollers (molds) that progressively bend flat metal coils into trapezoidal corrugated or ribbed profiles.
Cutting Device: Automatically cuts formed roof panels to preset lengths (fixed-length cutting).
Control System: Uses PLC or CNC systems to regulate speed, length, pressure, and other parameters, enabling automated production.
Auxiliary Modules: Optional add-ons like punching, embossing, or coating units to meet diverse functional requirements.
2. Working Principle
1. Uncoiling: Metal coils are straightened by a leveling machine before entering the roll forming system.
2. Multi-stage Roll Forming: The metal sheet passes through successive roller sets, gradually shaping it into a trapezoidal cross-section (profile determined by mold design).
3. Fixed-length Cutting: Finished panels are automatically cut to specified lengths and stacked or packaged.
3. Technical Features
High-speed Continuous Production**: Processes 5-30 meters per minute (depending on material thickness and machine model).
Precision Forming: Precision-engineered rollers ensure dimensional consistency and structural strength of panels.
Customizable Design: Interchangeable molds enable production of trapezoidal panels with varying rib heights, spacings, and profiles (e.g., U-shape, V-shape, trapezoidal ribs).
Energy Efficiency & Eco-friendliness: Cold-forming process requires no heating, minimizing energy consumption and pollution.
