This article explores the workings, advantages, applications, components, and maintenance of double stage roll forming machines, shedding light on their significance in modern manufacturing processes.
2. What is a Double Stage Roll Forming Machine?
A double stage roll forming machine is an advanced piece of equipment used to convert flat metal coils into custom-designed profiles with consistent cross-sections. It operates in a continuous process, ensuring a high level of efficiency and accuracy in metal forming. The double stage system refers to the presence of two sets of roll forming stations, enabling the production of more complex profiles in a single pass.
3. How Does a Double Stage Roll Forming Machine Work?
The operation of a double stage roll forming machine involves multiple stages. Initially, a coil of metal is loaded onto the uncoiler, and the coil car feeds the metal to the machine. The material then passes through the first set of roll forming stations, where it gradually takes the desired shape. After the first stage, the partially formed profile enters the second set of roll forming stations, undergoing further shaping and refinement. Finally, the cut-off system trims the profile to the desired length.
4. Advantages of Double Stage Roll Forming Machines

6. Key Components of a Double Stage Roll Forming Machine
6.1 Uncoiler and Coil Car
The uncoiler serves as the starting point of the roll forming process. It holds the metal coil and gradually feeds it into the machine. The coil car facilitates easy loading and positioning of heavy metal coils onto the uncoiler, ensuring a smooth material supply to the forming stations.
6.2 Feeding System
The feeding system consists of rollers and guides that guide the metal coil through the machine. It ensures a consistent and precise feeding of the material into the roll forming stations, minimizing material wastage and ensuring accurate profile formation.
6.3 Roll Forming Stations
The heart of the double stage roll forming machine lies in its roll forming stations. These stations consist of a series of rollers, each carefully shaped to bend the metal progressively into the desired profile. The number and configuration of these stations depend on the complexity of the profile being formed.
6.4 Cutting System
Once the metal has passed through all the roll forming stations, the cutting system comes into action. It cuts the continuous profile into individual pieces of the desired length. Various cutting mechanisms, such as flying shears or hydraulic cutters, are employed based on the requirements of the manufacturing process.
6.5 Control System
The control system is the brain of the double stage roll forming machine. It ensures smooth coordination between various components and processes. Advanced control systems utilize programmable logic controllers (PLCs) and human-machine interfaces (HMIs) to enable easy operation, real-time monitoring, and troubleshooting.
