Garage Door Roll Forming Machine Complete Understanding

Garage doors are an essential part of any home or building. They provide security, insulation, noise reduction, and curb appeal. Traditional garage doors were often heavy, inefficient, and prone to wear and tear. The advent of roll forming technology revolutionized garage door manufacturing, providing lighter, stronger, and more energy-efficient doors. This article will explore everything you need to know about garage door roll forming machines.

Qu'est-ce qu'une machine de formage de rouleaux ?

Roll forming is a metal working process that forms metal sheets into customized profiles using a series of consecutive roller dies. The roller dies progressively shape the sheet as it passes through each station of the roll former. This incremental rolling action gradually forms the metal into the desired shape.

Roll formed products have a high degree of accuracy and consistency. The roller dies can form complex profiles that might be difficult or impossible with other fabrication methods. In addition, the roller dies only contact the edges of the sheet metal, not the entire surface. This helps prevent scratches or markings on the surface of the profile.

Benefits of garage door roll forming machines

Using roll formed garage doors offers numerous advantages over traditional doors:

  • Lighter weight – Roll formed steel doors weigh up to 50% less than wood or fiberglass doors. The lighter doors make for easier installation and operation.
  • Superior strength – The incremental rolling process work-hardens the steel, increasing its strength. Roll formed doors resist dents and damage.
  • Efficacité énergétique – The tight tolerances of roll formed doors reduce air infiltration. Insulated doors provide thermal efficiency.
  • Durabilité – Roll formed steel resists rot, decay, and insect damage better than wood or fiberglass. The doors enjoy a long service life.
  • Réduction du bruit – The rigid steel construction dampens noise transmission better than other materials.
  • Esthétique – Steel doors accept a wide range of ornamental patterns and finishes for great curb appeal.

For these reasons, roll formed doors now dominate the residential garage door industry.

Parts of a Roll Formed Garage Door

While designs vary, most residential roll formed garage doors consist of three main components:

Panneaux

The door panels form the main surface area of the door. Most standard residential doors contain four to six panels. The most common panel style features distinctive horizontal grooves across the length of the panel. Other popular options include short raised panels, long raised panels, flush panels, and wood grain textures.

Insulation can be sandwiched between an inner and outer metal skin to improve the door’s thermal efficiency. Polyurethane foam provides optimal insulation properties.

Hinges and Brackets

Hinges connect the panels together, allowing the door to articulate. Standard residential doors use heavy duty galvanized steel hinges. Commercial and industrial doors may incorporate aircraft quality hinges for extra durability.

Mounting brackets attach the hinged door panels to the track system along the sides of the doorway. The brackets are typically made from galvanized steel or other corrosion resistant materials.

Pistes

Tracks guide the door up and down along the doorway’s jambs. Most residential doors use vertical tracks with a short horizontal section for the top panel to rest on when open. Commercial and industrial doors often feature full horizontal tracks along the ceiling for additional clearance. The tracks are formed from galvanized steel for corrosion resistance. High quality nylon or steel rollers inside the brackets glide smoothly along the track.

The Roll Forming Process

Constructing a roll formed garage door involves gradually transforming flat metal coils into shaped door components through multiple rolling stages:

1. Uncoiling

Coiled steel sheet gets mounted onto a de-coiler which unrolls and straightens the steel prior to forming. This unwinds the coil and feeds a straight sheet into the roll former.

2. Préformage

Optional pre-forming rollers make initial light indentations along the sheet to facilitate the subsequent rolling phases.

3. Forming

The heart of the process – the sheet passes through consecutive forming rollers which incrementally bend, shape, and crimp it into the final profile. The rollers only contact the sheet along its edges, not the face.

4. Cutting

A rotating saw blade or hydraulic shear cuts the formed sheet into appropriately sized sections as it emerges from the final forming rollers.

5. Hardware Attachment

Hinges, brackets, insulation, and other hardware fixtures get affixed to the cut door sections.

The roll formed components then go to final assembly, packaging, and shipping.

Configurations des profileuses

The modular nature of these machines allows for many possible configurations:

  • En ligne – The decoiler, pre-forming, forming, and cutting stations align end-to-end for efficient high volume production.
  • Compact – For space constrained shops, the stations can stack vertically with the sheet making 90 degree turns between stations.
  • Powered – Powered machines utilize motors and gears to continuously pull the sheet through each station.
  • Manuel – Manual machines rely on hand cranks or chains to advance the sheet. Manual operations suit low volume production.
  • Number of heads – More heads allow for more complex profiles and increased throughput. 12-16 heads are typical for garage doors.
  • Customizable tooling – Roll former tooling is customizable with different roller dies to produce specialized door profiles.

No matter the layout, all roll formers work on the same fundamental principle of progressive incremental rolling.

Spécifications typiques

While specs depend on the machine model and manufacturer, most roll forming lines for garage doors fall into the following ranges:

  • Sheet width capacity – 50 to 100 inches
  • Sheet thickness capacity – 28 to 22 gauge
  • Roll stations – 10 to 20
  • Forming speed – 15 to 40 feet per minute
  • Motor power – 3 kW to 7.5 kW
  • Decoiler capacity – 5,000 to 20,000 pounds

Major Components of a Roll Forming Machine

Roll formers contain a number of key components engineered to work together:

  • Dérouleur – This unwinds the coiled sheet and feeds it into the first stations. It contains adjustments for sheet width and tension.
  • Table d'alimentation – Supports and guides the sheet into the initial forming rollers. Often includes pre-forming indent rollers.
  • Forming heads – The consecutive rolling heads that progressively shape the sheet. Constructed from machined steel, iron, or a combination.
  • Rouleaux – Hardened steel rollers within the forming heads that contact and bend the sheet. Different profiles require unique roller shapes.
  • Forming motors – Provide power to turn the rolling heads and pull the sheet through the machine.
  • Poste de coupe – Saws or hydraulic shears that cut the formed sheet into properly sized sections.
  • Contrôles – Operators control the speed, feed, and cutting from a master control panel.
  • Guides – Rollers and channels that support the sheet throughout the forming and transport process.
  • Cadre – A rigid steel frame houses the components and maintains precise alignment.
