Key Features of Ameco Roll Forming Machines

Ameco roll formers incorporate rugged construction and several design elements that make them versatile, easy-to-use and built to last:

  • Heavy duty steel frame construction – Made from steel I-beams and thick steel plate components which dampens vibration and allows high speed operation.
  • Industrial strength drive system – Hardened helical gearbox provides smooth power transmission and reduced maintenance. TEFC motors with electronic variable speed provide precise speed control.
  • Quick change forming heads – Modular tooling design allows easy profile changeover by switching tool packs. Minimizes downtime between production runs.
  • Easy coil loading – Side or rear loading of coils from 33lbs to 5000lbs capacity. Powered decoilers available for heavy coils.

  • Servo roll spacing adjustment – Servo motors allow quick and repeatable adjustment of roll spacing to control material thickness.
  • Safety enclosures – Enclosed nip point guards, emergency stops and interlocks for operator safety.

Roll Forming Process Basics

The roll forming operation works by gradually forming the profile in incremental steps by bending the strip through consecutive roller stations. Each roller station incrementally forms the material to the next stage of the profile shape.

The key steps in the basic roll forming process are:

  • Кормление – The strip (usually coiled metal) enters the roll former and is fed through by powered feed rolls.
  • Bending – As the strip passes through the roller stations, the rollers produce incremental bends that gradually form the material.
  • Shaping – By the exit end, the desired profile shape is completely formed through the sequential roller bends.
  • Cut-off – The finished profile is cut to length by a shearing end cut-off.
  • Exit – The formed product exits the roll former where it can be manually offloaded or automatically stacked.

The number of roller stations and complexity of tooling will vary considerably based on the final profile design. Simple profiles like square or rectangle tubes may only require 5-6 stations while complex shapes need 20 or more stations.

Design Considerations for Roll Formed Parts

Roll forming allows continuous production of profiles but the part shapes that can be produced are limited by certain design considerations:

  • Constant cross-section – The profile must have a continuous cross-section without interruptions along the length.
  • No sharp corners – Radiused bends and gradual transitions are required since material cannot be formed at sharp right angles.
  • Simple surfaces – Complex 3D curves or extrusions are generally not possible. Profiles are limited to single plane shapes.
  • Bend orientation – Bends are usually limited to one plane across the width only, not along the length. Some edge crimping may be possible.
  • Springback – The elastic springback effect after bending may require overbending and compensation in the roller design.
  • Tooling access – Tooling must be accessible horizontally from the side so may require profile split into two planes.
  • Strip properties – Ductility of the material and width/thickness ratios will determine formability.

Ameco’s design engineering team can provide guidance on the geometries feasible with roll forming based on the desired material specifications and production requirements.
