Alüminyum Rulo Şekillendirme Makinesi Çeşitleri

Aluminium roll forming machines are used to form aluminium coils into custom profiles and geometries for a wide range of applications. This comprehensive guide provides an overview of aluminium roll forming technology, the types of machines available, their key components, technical specifications, applications, advantages, limitations, and more.

Overview of Aluminium Roll Forming Machines

Roll forming is a continuous bending operation in which a long strip of metal is passed through consecutive sets of rolls, or stands, each performing only an incremental part of the bend, until the desired cross-section profile is obtained.

Roll forming aluminium provides a cost-effective way of producing custom aluminium parts with accurate and repeatable tolerances. Aluminium’s excellent formability allows it to be shaped via roll forming into a variety of complex geometries.

Compared to alternatives like extrusion, roll forming is advantageous for shorter production runs, lower cost per unit, and easier profile modifications. It enables flexibility for producing aluminium parts in a wide range of shapes, sizes and finishes.

Modern aluminium roll forming lines utilize advanced 3D modelling, precision roller positioning, and controls to efficiently mass produce aluminium sections on demand.

Key Benefits of Aluminium Roll Forming

  • Continuous, high speed production of long length aluminium parts
  • Cost-effective for medium to high volume requirements
  • Tighter tolerances and better consistency versus other methods
  • Flexible in adjusting profiles by modifying roller positions
  • Allows complex custom shapes and bends
  • Range of aluminium finishes possible – mill, anodized, powder coated

Limitations of Roll Forming Aluminium

  • Higher initial setup costs for roll tooling
  • Limited by maximum aluminum width/thickness that can be fed
  • Minimum bend radii restrictions
  • Designs need to allow movement of profiles during bending
  • Lower dimensional accuracy versus aluminum extrusions

Main Components of Aluminium Roll Forming Machines

Aluminium roll forming systems have three main sections – the roll forming stands, the material feeding system, and the exit end for cutting and handling formed profiles.

Rulo Şekillendirme Standları

The roll forming section has a series of roll stations, each with an upper and lower set of rolls. Typical configurations have between 5-16 stands arranged in a straight line.

  • Roll stations make progressively deeper bends to shape the profile
  • Heavy duty gearbox actuators precisely position upper rolls
  • Roll geometries match desired contour of the profile
  • Roll materials – steel, carbide, zinc plated, etc.

Material Feed System

This unwinds and feeds the aluminium coil strip into the roll forming section at a controlled speed and tension.

  • Coil holding mandrel + de-coiler mechanism
  • Feed tables with pinching drive rollers
  • Feedback controls for automatic speed adjustment
  • Edge guidance system to keep strip centered

Cutoff and Exit End

Formed aluminium profiles are cut into desired lengths and discharged out of the machine.

  • Flying shears or fixed knives for profile cutoff
  • Powered exit tables or conveyors
  • Stackers to neatly arrange cut aluminium parts

Kontrol Sistemi

Advanced roll formers use PLC-based controls for monitoring and coordinating all machine elements.

  • HMI touchscreen for controlling production
  • Servo motor drives with position feedback
  • Sensor feedback for automatic speed control
  • Safety interlocks and operational modes

Design Considerations for Roll Forming Aluminium

Roll forming enables great flexibility in producing custom aluminium profiles, but the cross-section design must follow certain guidelines.

  • Simple, constant cross-section along length
  • No holes or extruded features
  • Limit complex concave shapes
  • Avoid quick changes in profile
  • Radius bends only (no sharp corners)
  • Account for springback after bending
  • Wall thickness impacts minimum radii
  • Consider machine capacity limits

Advanced 3D modelling helps optimize designs for roll forming performance, material utilization, and tooling longevity.

Aluminium Materials for Roll Forming

Common aluminium alloys used for roll forming include:

  • 1xxx series – Excellent corrosion resistance, low strength
  • 3xxx series – Medium strength, good formability
  • 5xxx series – High strength, good formability
  • 6xxx series – Medium strength, good extrudability

5xxx alloys like 5052, 5083, 5754 are most popular for roll formed aluminium goods. Finishes can be mill finish, painted, anodized, or powder coated.

Roll Tooling for Profile Designs

Roll tools are precision machined to match the contours of the desired profile shape.

  • Made from tool steel or carbide
  • Ground and hardened rolls
  • Upper rolls are adjustable
  • Quick change systems to swap roll sets

CAD software creates roll geometries by virtually bending flat strips and unfolding to get roller profiles.

Roll tools represent significant upfront cost, so it is economical for long production runs of the same profile. Tooling modifications can alter profiles.

Comparing Roll Forming and Extrusion of Aluminium

Roll forming and extrusion offer two different manufacturing methods for producing long aluminium parts with custom cross-sections.

Aluminum Extrusion

  • Complex internal and external shapes
  • Tight dimensional tolerances
  • Smooth surface finish
  • Fast production of simple profiles
  • High upfront extrusion die cost
  • Limitations on length

Aluminum Roll Forming

  • Only open profiles possible
  • Dimensional accuracy +/- 0.5mm
  • Surface markings from rollers
  • Lower cost for medium production runs
  • Adjustable roll tooling
  • Continuous production of long lengths

Roll forming competes on cost for simpler, linear geometries needed in longer lengths, while extrusion is better for complex profiles with finer features.

3. Feed Aluminium Strip into Machine

  • Coil loaded onto de-coiler
  • Strip feeds through pinch rollers into first rolls
  • Lead-in guides stabilize strip

4. Pass Through Progressive Roll Stands

  • Strip consecutively shaped by each roll station
  • Gradually bent into final profile
  • Adjust individual rolls to tune profile

5. Cut Formed Profile to Length

  • Exit section shears or saws cut parts to length
  • Conveyors transport finished pieces

6. Conduct Finishing Operations

  • Anodizing, powder coating enhances appearance
  • Holes punched, ends deburred
  • Products packed, inspected, and shipped

Understanding each step helps identify potential improvements and optimizations. Proper setup is critical prior to production. Adjustments during operation fine tune the process.

Types of Aluminium Roll Forming Machines 6


Q: What size aluminium coils can be roll formed?

A: Most roll forming machines accept coil widths ranging from 200 mm to 2100 mm. Standard coil IDs range from 150 mm for narrow coils up to 700 mm for wide coils. Strip thicknesses typically range from 0.3 mm to 4 mm. Maximum coil weights depend on the decoiler capacity but are usually 1 to 3 tons.

Q: What aluminum grades work best for roll forming?

A: Alloys in the 1xxx, 3xxx, and 5xxx series have good formability and are commonly roll formed. 5xxx alloys like 5052, 5083, and 5754 are most popular. 6xxx alloys require special roll pass design. 2xxx and 7xxx alloys have poor formability.

Q: Does roll forming weaken aluminium?

A: The cold working of the roll forming process actually increases the strength and hardness of aluminum through work hardening. The repetitive bending under tension cold works the material. Proper machine setup and roll design prevents cracking.

Q: How many roll stands are needed?

A: Most applications require 8 – 16 stands of rolls. Profiles with deeper shapes or smaller radii may need up to 20 stands. Simple profiles can be formed with as few as 5 stands. More stands allow more incremental bending for improved control.

Q: How long can roll formed parts be?

A: Many roll forming lines produce aluminum up to 200 m long by continuously feeding coil strip through the machine. Flying cutoffs slice profiles at the required lengths for the application. Lengths are limited by the coil size and machine layout.

Q: What tolerances are possible with roll forming?

A: Roll formed aluminum typically achieves profile tolerances around +/- 0.5 mm. More advanced machines can achieve +/- 0.3 mm accuracy. Tolerances primarily depend on material consistency and machine precision.
