Double layer roll forming machines are designed to produce two different metal profiles in one machine, making them a versatile and space-efficient option for production. Here are the typical specifications and descriptions of a double-layer roll forming machine:
1. General Specifications
Material Thickness: 0.2-1.0 mm (for lighter materials like aluminum or soft metals) up to 1.5 mm for heavy-duty applications.
Material Width: Varies based on profile requirements but typically ranges from 600 mm to 1,250 mm.
Material Type: Galvanized steel, aluminum, copper, or coated steel.
Machine Dimensions: Length (6-12 meters), Width (1.5-3 meters), and Height (1.5-3 meters) depending on machine complexity and profile types.
2. Profile Types
Top Layer: Configured for one profile, such as trapezoidal or corrugated sheets.
Bottom Layer: Configured for a different profile, e.g., standing seam or different corrugated style.
Profile Changeover: Manual or automated selection allows switching between the two profiles without time-consuming die changes.
3. Key Components
Decoiler: Typically handles up to 5-ton coils, with options for manual or hydraulic operation.
Feeding System: Guides the sheet smoothly to prevent misalignment.
Roll Forming System: Two independent sets of rollers, one for each profile, providing high precision and durable shapes.
Cutting System: Hydraulic cutting system that precisely trims both profiles without burrs or distortions.
Control System: PLC-based, user-friendly interface allowing for easy adjustment of production parameters, including profile type and length of sheets.
Hydraulic System: Powers the cutting and changeover process, with oil cooling to ensure reliable performance under continuous operation.
4. Performance
Production Speed: Typically 10-20 m/min, adjustable depending on the thickness and material type.
Motor Power: Ranges between 5-15 kW for each layer, depending on material thickness and speed requirements.
Power Supply: Configurable to meet local standards (380V, 50Hz, 3-phase or as required).
5. Applications
Double-layer roll forming machines are ideal for manufacturers producing roofing sheets, wall panels, and decorative metal profiles where space or cost limitations require flexible production on one machine.
Industries like construction, roofing, and agricultural storage benefit significantly from these machines due to the variety of profiles they can produce.
