A Double Layer T Wave Roll Forming Machine is a highly specialized piece of industrial equipment used in the construction industry to continuously produce double-layer T Wave steel sheets from metal coils. These sheets are a key component in the construction of standing seam roof and wall systems.
The machine is a complex assembly line comprising several stations. Here are the key components:
1.Uncoiler / Decoiler: A heavy-duty stand that holds the large coil of raw sheet metal (typically steel, aluminum, or zinc). It often includes a braking system to maintain tension.
2.Entry Guide & Levelling Unit: This ensures the metal strip enters the forming section perfectly straight and flat, eliminating any coil memory or curvature, which is critical for a consistent final product.
3.Double Layer Forming Section (The Heart of the Machine): This is a long series of stands, each containing a set of precision-engineered rollers (rolls).
4.Dual Forming Lines: The machine essentially has two parallel forming paths. One path gradually shapes the metal for the outer panel, and the other path shapes the metal for the inner panel.
5.Progressive Forming: The rollers in each successive stand bend the metal a little more than the previous one. This gradual, cold-forming process prevents material stress and ensures a precise, consistent profile without cracking the metal or damaging its protective coating (e.g., paint, galvanization).
6.Cutting System: Located after the forming section, this cuts the continuously produced double-layer panel to the required length. Common types are:
Flying Cut-Off: A hydraulic or servo-driven shear that moves synchronously with the moving panel, makes a clean cut, and returns to its start position. This allows for continuous production without stopping.
Post Cut: The machine stops briefly for the cut, which is less efficient for high-volume production.
7.Output Conveyor & Stacking System: A powered roller conveyor that supports the freshly cut panels and transports them to an automatic stacking station, ready for bundling and shipment.
8.PLC Control Cabinet: The brain of the operation. A Programmable Logic Controller (PLC) and Human-Machine Interface (HMI) touchscreen allow the operator to input parameters (panel length, quantity, production speed) and monitor the entire process.
High Efficiency & Speed: Continuous production far outstrips manual or press-brake methods.
Exceptional Consistency: Every panel is identical, ensuring perfect fit during installation.
Superior Seam Quality: Creates a robust, weather-tight seam that is highly resistant to leaks and wind.
Material Savings: Minimizes waste by using coiled stock efficiently.
Labor Savings: Automates a complex forming process, requiring minimal operator intervention.
When specifying such a machine, key parameters include:
Material Thickness: (e.g., 0.4mm - 1.2mm).
Material Width (Coil): (e.g., 1000mm - 1300mm).
Production Speed: (e.g., 10 - 25 meters per minute).
Panel Length Range: (e.g., 2m - 16+ meters).
Forming Stations: Number of roll stands (e.g., 18-25 stations).
Drive System: Servo motors for high precision.
Control System: Brand of PLC and HMI.
In summary, a Double Layer T Wave Roll Forming Machine is a sophisticated, automated production line that transforms flat metal coil into high-performance, double-layer building panels with a superior interlocking seam, forming the backbone of modern commercial and industrial construction.
