Light Steel Keel Roll Forming Machines

Light steel keel roll forming machines are an essential equipment used for manufacturing light steel keels and frames for the construction industry. This guide provides a comprehensive overview of light steel keel roll forming machines covering their working, types, main components, specifications, applications, advantages, limitations and more.

Overview of Light Steel Keel Roll Forming Machines

Light steel keel roll forming machines are designed to cold-form different light steel sections and profiles used as load bearing members in light steel framed buildings and structures. They continuously form structural C,U,Z,Sigma and other shaped profiles from steel coil of thickness 0.7-2.0mm into required cross-sections by gradually bending the strip through a series of roller dies.

Compared to other steel structural members, light steel keels and studs formed by these machines offer advantages like light weight, high strength, easy and fast installation, design flexibility, environment friendly construction and more. They find wide applications in walls, floors, roofs and frameworks for residential, commercial and industrial buildings.

The most important components of a light steel roll forming machine include the decoiler unit, feeder, pre-cutter, roll forming stations, post-cutter and other auxiliary devices. Based on number of profiles produced, they are available in single and multi-profile designs from various manufacturers around the world.

Main Features of Light Steel Keel Roll Formers:

  • Cold roll high strength light steel coils into C,U,Z,Sigma and custom profiles
  • Form keels up to 2mm thickness and 200mm height
  • Output up to 120m/min with tolerance +/-0.5mm
  • PLC controller for automatic production
  • Roller dies made of wear-resistant materials like GCr15 steel
  • Computerized hydraulic decoiler for feeding coil strips
  • Servo motors for precision feeding and cutting
  • Easy size changeovers with quick change forming rollers
  • Safety devices like strip breakage detection sensors
  • Optional inline punching units and stackers

Working Principle of Light Steel Keel Rolling Machines

The working principle involves continuously forming structural light steel sections from steel coil by passing it through a series of roller dies that gradually bend the strip into the required profile shape.

Steps in Light Steel Profile Roll Forming Process:

  1. Decoiling – The decoiler feeds the light gauge steel coil strip into the roll former
  2. Feeding – Feed rollers grip the strip and pull it through the forming stations
  3. Pre-cutting – Cuts the strip to preset lengths for forming keel frames
  4. Roll forming – Strip passes through series of stands with roller dies to bend it
  5. Post-cutting – Cuts formed profiles to required lengths
  6. Counting and stacking – Formed keels are counted and stacked automatically

The roller dies are the key forming parts arranged in stands along the machine line. As the strip passes through each stand, the rollers make gradual bends until the final profile shape is achieved. The number of stands required depends on the complexity of the section.

Precise feed control, well aligned roller dies and optimal pass schedules are critical to achieve the tight tolerances and high quality demanded for structural light steel profiles.

Advanced machines also integrate inline processes like punching holes, embossing logos and automated stacking for complete production in a single line.
