Roll forming machines are industrial production equipment that transforms metal sheets into desired profiles and shapes. In order for these machines to operate efficiently and without interruption, the metal coils must be fed smoothly and continuously. Mechanical decoilers are one of the important components that perform this task.

What is a Mechanical Decoiler?

Mechanical decoilers are systems that allow metal rolls to be unrolled and fed flat. These openers are especially preferred by businesses looking for simpler and low-cost solutions. Mechanical decoilers operate on mechanical principles rather than hydraulic or electrical systems.

Advantages of Mechanical Decoilers

1. Economical Solution: Mechanical decoilers offer a more economical solution than hydraulic or pneumatic systems. This is a great advantage, especially for small and medium-sized businesses.

2. Simple Design: Mechanical decoilers have a less complicated design. This simplifies maintenance and repairs and allows them to be carried out at lower costs.

3. Reliability: Mechanical systems are long-lasting and durable. This ensures uninterrupted and reliable operation of roll forming machines.

4. Ease of Use: Mechanical decoilers can be easily managed and adjusted by operators with their user-friendly structure. This increases the efficiency of production processes.

Components of Mechanical Decoilers

1. Roll Holder: The roll holder allows the metal roll to be securely placed and fixed. This part prevents the roll from slipping or falling.

2. Unwinding Mechanism: The unwinding mechanism ensures that the roll is unrolled and fed smoothly. This mechanism controls the rotation of the roll and the advancement of the metal sheet.

3. Brake System: The brake system allows the roll to be opened at the desired speed and the metal sheet to be fed without stress. The braking system controls the speed at which the roll is unrolled, ensuring that the production process is uninterrupted and smooth.

4. Frame and Structural Elements: Mechanical decoilers have a sturdy frame and structural elements. These elements ensure stable and safe operation of the openers.

Maintenance of Mechanical Decoilers

Regular maintenance is necessary for mechanical decoilers to operate efficiently. Here are the important steps for maintenance:

1. Regular Checks: Decoilers should be checked visually and functionally regularly. These checks allow early detection of possible signs of wear, damage or deterioration.

2. Lubrication: Regular lubrication of  moving parts reduces friction and prevents wear. The use of appropriate lubricants prolongs the life of the machine.

3. Cleanliness: Keeping mechanical decoilers clean prevents accumulated dust and metal particles from damaging the mechanical components. Cleaning should be done at regular intervals.

4. Parts Replacement: Worn or damaged parts should be replaced in a timely manner. When replacing parts, it is recommended to use original spare parts.

Spare Parts of Mechanical Decoilers

In order for roll forming lines to run smoothly, it is important to have spare parts for mechanical decoilers available. Here are the frequently needed spare parts:

1. Bearings: Bearings are one of the most critical components of mechanical decoilers. Bearings operating at high speeds can wear out over time and need to be replaced.

2. Brake Components: In order for the brake system to function properly, it is important to check the brake components regularly and to have backups ready.

3. Chains and Sprockets: Chains and sprockets are the mechanical components that enable the movement of decoilers. They should be replaced when they are worn or damaged.

4. Springs and Fasteners: Springs and fasteners ensure the structural integrity of the decoilers. It may wear out or break over time. Regular checking and replacement as needed ensures smooth operation of the line.

Result

Mechanical decoilers are an important component for efficient and uninterrupted operation of roll forming machines. Thanks to their economical, simple and reliable structure, they are especially preferred in small and medium-sized enterprises. With regular maintenance and proper spare parts management, mechanical decoilers can be ensured to have a long life and trouble-free operation.
