What are the main components of a roll-forming machine?

A roll-forming machine fabricates long strips of metal, bending and manipulating them into different shapes according to specific configurations.

These machines also can perform several other metalworking duties, such as material cutting and roll punching.

The majority of roll-forming machines work in a continuous cycle. This means the metal coil will be fed into one end of the device and will be passed through each of the machine's components continuously until the final product exits at the end.

Roll forming machines have several stations where rollers are used to create the bends in the metal according to the specifications, each set of rollers bending the metal further to complete the required shape in a progressive cycle.

Roll forming machines are highly efficient, operating at speeds between 30 to 600 feet per minute. This makes them essential for businesses that require huge numbers of the same metal precise products to be manufactured over time.

All roll forming machines have the same essential design components. These include:

De Coiler - this is where the metal coil can be loaded and will be uncoiled according to the pre-programmed speed.

Strip accumulator and slack loop - this component allows the coil strip to pause, allowing for a pre-punch press stroke without disrupting the roll form mill.

Feeding roller and leveling - where the metal is straightened and leveled out in preparation for manipulation.

Pre-punching and marking - in some designs, holes are required before the metals bent into its final shape.

Forming stations/ the roll die mill - this is where the material is progressively passed through various sets of rollers, each set manipulating the metal a little more. Once this has taken place, the part is then passed through several straightening dies and side rollers to ensure complete accuracy. This process will eliminate any twist, bow, or camber of the metal, which could end up distorting the final shape. This component in the process can also be referred to as torque head or final guide.

Cutting and discharge - the final stage is where the cutting system - a hydraulic or mechanic saw will cut the metal to its precise length without disrupting the flow of the process. The resulting part will then be discharged onto the run-out table, ready for storage or shipment.

Developments in roll forming machines

Many modern roll forming machines boast Computer-Aided Design (CAD) systems. These provide roll-forming machines with the ability to ensure complete accuracy, tighten tolerance levels, and catch any product imperfections early, thus reducing waste and maximizing business profits.
