Flying-Shear Roll Forming Machines

Flying-shear roll forming machines utilize a unique cut-to-length system to boost efficiency in roll formed profile production. The flying shear mechanism shears the moving strip just before it enters the roll forming section.

Key details about flying-shear roll formers:

  • Cut-to-length system integrated into roll former
  • Rotary shear cuts moving strip at high speed
  • Precise shear timing synchronized to line speed
  • Permits faster overall line speeds
  • Quick and easy size changes
  • Used for metals up to 4mm thickness
  • Ideal for producing parts in standard lengths
  • Commonly used to make roofing panels, decking, and panels

By removing the stop-and-start action of typical end shears, flying shears optimize the roll forming process.

Types of flying-shear roll forming machine

Machine TypeDescription
MechanicalShear timing via Geneva mechanism and servo drive
ElectronicShear controlled by PLC with encoder feedback
HydraulicHydraulic cylinder actuates shear at right moment

Mechanical flying shears precisely time the cut mechanically for a simpler, economical design.

Electronic flying shears offer more flexibility and speed control through the system’s logic controller.

Hydraulic flying shears generate high shearing force while maintaining accurate timing.

Benefits of Flying Shear Roll Forming Lines

  • Faster production than standard roll former with end shear
  • Precisely cut parts immediately off the roll former
  • Quick and easy size changeovers
  • Increased throughput from uninterrupted strip flow
  • Ideal for producing profiles in standard lengths
  • Consistent cut tolerance and quality
  • Compact design minimizes space
  • Lower labor requirements
  • Ability to cut to length on the fly
  • Simpler material handling

Key advantages include speed, changeover ease, consistency, and labor savings versus typical stop-and-cut systems.

Limitations of Flying Shear Roll Forming Technology

  • Higher initial capital cost than standard roll formers
  • Requires more maintenance and skilled operation
  • Limited to thinner/softer material gauges
  • Not as easy to cut non-standard length parts
  • Precise alignment critical for smooth operation
  • Timing mechanisms can wear over time
  • Special tooling required for different profiles
  • Can increase roll changing time during size changes
  • Scrap generation during initial setup

The main limitations relate to higher cost and maintenance requirements versus basic roll formers.

Cost Comparison of Flying Shear vs End Shear Machines

Machine TypePrice RangeBenefitsDrawbacks
Flying Shear$150,000 – $300,000Faster speeds, easy length changesHigher cost, specialized maintenance
End Shear$100,000 – $200,000Lower initial cost, simple operationSlow cut-to-length method

Flying shears improve productivity but have higher capital and operating costs. Evaluate based on volume, changeovers, and budget.

Troubleshooting Issues with Flying Shear Roll Lines

IssueSolution
Inaccurate shear timingAdjust/replace worn gears; check encoder
Blade wearRotate/replace shear blades
Strip marksIncrease blade/roll hardness; adjust guides
Hydraulic leaksReplace seals, hoses, cylinders
Excess vibrationCheck alignment, mountings; repair as needed
Electrical faultsCheck/replace wires, connections, drives

Proper blade maintenance along with swift repairs of leaks, looseness, or electrical problems prevents unplanned downtime.
