Working Process of High-Speed Roll Forming Machines
The roll forming process involves several key steps to transform a flat metal strip into a desired profile:
- Material Feeding: The metal strip, usually supplied in coils, is fed into the roll forming machine.
- Roll Forming: The strip passes through a series of rollers that gradually shape the metal into the desired profile. Each set of rollers performs a specific bend or shape, ensuring precision and consistency.
- Cutting: After the metal strip is formed, it is cut to the required length using either a flying cutoff saw or a post-cut die.
- Quality Control: The final products are inspected to ensure they meet the required specifications and tolerances.
