A Comprehensive Overview of Decoiler Systems Used in Roll Forming Machines

Roll forming machines are industrial equipment used to convert metal sheets into desired profiles. There are many components used to ensure efficient and uninterrupted operation of these machines. One of these components is decoiler systems.

The Role of Decoiler Systems in Roll Forming Machines

Decoiler systems undertake the task of opening the rolled metal sheets fed to the roll forming machines and making them planar. In this way, the boards are made ready for forming processes. Decoiler systems are a critical component that directly affects the productivity of the machine.

Types and Working Principles of Decoiler Systems

Decoiler systems can be broadly classified as follows:

• Mechanical Decoilers:
  • They have a simpler structure and cost less.
  • Friction or pneumatic brake options are available.
  • Thanks to the frequency inverter, motor speed and acceleration control is provided.
  • They can rotate in both directions manually or automatically.
• Hydraulic Decoilers:
  • They have more complex structure and higher capacity.
  • Drum tightening is carried out by a hydraulic system.
  • They can work semi-automatically or fully automatically.
  • They can roll out rolls of different widths and diameters.
• Servo Motor Decoilers:
  • It is used in applications that require high precision and repeatability.
  • Thanks to the servo motor control, the coil sheet is loaded in a centered manner on the drum.
  • Double drum options are available.

Working Principle:

The basic working principle of all decoiler systems is to unroll the rolled metal sheet by clamping it between two or more drums. The rotational speed and pressure of the drums are adjusted according to the thickness and material of the board. In this way, the sheet is made ready for the forming process.

Selection of Decoiler Systems

The choice of the right decoiler system depends on the characteristics of the profile to be produced, the dimensions of the rolls and the production speed. When choosing, the following factors should be taken into account:

• Dimensions of rolls (width, diameter, thickness)
• Production speed
• Complexity of the profile
• Material properties
• Budget

Advantages of Decoiler Systems

• High efficiency: Thanks to the decoiler systems, production processes are accelerated and productivity increases.
• Uninterrupted production: Decoiler systems with regular maintenance ensure long-term uninterrupted production.
• Quality product: Smooth-rolled sheets allow for the production of higher quality profiles.
• Automation: Modern decoiler systems reduce operating costs thanks to their automation features.

Result

Decoiler systems are one of the indispensable parts of roll forming machines. Correctly selected and regularly maintained decoiler systems increase the efficiency of production processes and increase product quality.

Additional Information:

• Materials used in decoiler systems: Generally, high-strength steel and cast iron are used.
• Maintenance of decoiler systems: Periodic lubrication, cleaning and replacement of worn parts are required.
• Safety: Care should be taken and safety precautions should be taken when decoiling systems are working.
