Working Principle of Cable Tray Roll Forming Machines

Cable tray roll forming relies on the continuous bending and gradual shaping of metal coil strip into desired tray profiles through a series of progressions. The key processes involved are:

  • Material Feeding: Coiled metal strips are loaded at the unwinding station and fed into the machine.
  • Forming: The strip passes through a series of roll forming stands each with 2-3 rollers. The rollers progressively bend the metal to the designed shape.
  • Design and Sizing: The roller dies are customized to form trays of required size, depth, width and features like side hooks.
  • Slicing: Cutting blades slice the continuously formed metal strip at set lengths to create straight tray sections as per specified.
  • अनुकूलन: Additional stations can create holes, emboss patterns, apply surface finishes etc.
  • Output: Formed cable tray sections are offloaded for further processes like welding, surface treatment and installation.

The key to quality outcomes is precision roller design, accurate feeding, synchronized forming and cutting actions, with monitoring at each stage.

Types of Heavy Duty Cable Tray Roll Forming Machines

Heavy duty cable tray roll forming machines can be categorized based on structure, forming capability and automation level:

Machine TypeDescription
CagedRoller stations enclosed within a cage-like frame for safety
OpenRollers openly accessible for easy maintenance
FixedFixed size rollers, manual roller change for new profiles
Quick ChangeRoller cassettes or cartridges for fast profile changes
Semi-AutoManual material feeding and offloading
Fully AutoAutomated loading, forming, cutting and unloading

Selecting the right type depends on production needs, changeover frequency, level of operator skill, and budgets. Fully automated machines offer the highest productivity but have higher cost.

Key Materials Used in Cable Tray Production

Cable trays can be produced from different metals using heavy duty roll forming machines:

Materialविशेषताएँ
Mild SteelEconomical, strong
Stainless SteelCorrosion resistance
AluminumLightweight, conductive
Galvanized SteelRust resistance

Mild steel is the most common due to its strength, durability and cost effectiveness. Stainless steel and aluminum provide specialized properties like weather resistance or light weight, but are more expensive.

Roll Formed Cable Tray Design Considerations

Proper design of the roller tooling and dies is crucial for forming quality cable trays. Key parameters include:

  • Tray width and depth
  • Metal thickness and properties
  • Longitudinal stiffeners if needed
  • Roller diameters
  • Number and size of internal radii
  • Horizontal, vertical, inclined sections
  • Side hook design
  • Embossing and hole patterns

Advanced 3D modeling and simulation helps optimize the progressive die design before manufacturing the roller sets.

Customization of Roll Formed Cable Trays

Heavy duty roll forming lines offer various customization features:

  • Tray dimensions – width, depth, metal gauge as needed
  • Hook design – width, shape and size
  • Holes and Cutouts – size, shape and pattern
