Introduction to Trapezoidal and Corrugated Profile Double-Layer Roll Forming Machine
This is a highly specialized, high-efficiency cold roll forming machine primarily used for the continuous production of two different cross-sectional metal sheet products: trapezoidal ribbed panels (ribbed sheets) and corrugated sheets**. Its core design philosophy is "one machine, dual production" - enabling the production of two highly demanded types of architectural metal roofing and wall cladding panels **on the same machine, either simultaneously or through rapid switching.
Core Features & Advantages
1. Double-Layer" Design:This is the most distinctive feature.
Physical Structure: The machine is typically designed with upper and lower roll forming units.
Function Allocation:
One Layer (usually upper or lower) Dedicated to forming trapezoidal ribbed panels. These panels feature continuous trapezoidal or rectangular ribs, offering high strength and excellent drainage, commonly used for roofing or high-strength wall cladding.
The Other Layer: Dedicated to forming corrugated sheets. These sheets feature continuous curved undulations (like waves), providing an aesthetically pleasing appearance and moderate strength, commonly used for wall cladding, fencing, or lightweight roofing where aesthetics are important.
Simultaneous Production (Optional): Advanced models can feed material into and form both layers simultaneously, producing two different profiles at once, doubling efficiency.
Rapid Switching Production (Common):More commonly, the design allows operators to quickly switch the production line from one profile to the other (within minutes) via simple mechanical adjustments (e.g., switching guides, adjusting roll positions, or using quick-change die systems). This significantly enhances equipment utilization and production flexibility.
2. Roll Forming" Principle:
Metal coil (typically galvanized steel, prepainted steel, aluminum-magnesium-manganese, etc.) is uncoiled, leveled, and fed into the main forming section.
The main section consists of multiple sets of precisely designed forming rolls, arranged in pairs (vertical or horizontal).
The metal strip passes sequentially through these roll sets, undergoing progressive bending at room temperature to achieve the preset trapezoidal or corrugated profile.
The formed strip is cut to length, producing finished panels.
3. Target Products: Trapezoidal Ribbed Panels & Corrugated Sheets
Trapezoidal Ribbed Panels: Cross-section features a series of equally spaced, equal-height trapezoidal or rectangular ribs. Key parameters are rib height, rib width, and bottom width. Characteristics include high load-bearing capacity, efficient drainage, and a strong, modern appearance.
Corrugated Sheets: Cross-section features a series of equally spaced, equal-height continuous curved undulations (sine waves, arc waves, etc.). Key parameters are corrugation depth (height) and pitch (spacing). Characteristics include an attractive, flowing appearance, ease of installation, and wide applicability.
