Roll Bending in Continuous Bending Process

Roll bending is a continuous bending process that is used to produce long sections of formed shapes from coil or strip stock. In this process, opposing rolls are used to apply force to the material, which causes it to bend into the desired shape.

Process of Roll Bending

The process of roll bending involves the following steps:

1. Coil or Strip Stock: The process begins with a long coil or strip of material, typically metal. The material is fed into the roll bending machine, which consists of a series of opposing rolls.

2. Roll Pressure: The rolls apply pressure to the material, causing it to bend into the desired shape. The amount of pressure applied can be adjusted to produce different bending angles and radii.

3. Continuous Process: Roll bending is a continuous process, meaning that the material is fed continuously through the machine until the desired length of formed shape is produced.

Advantages of Roll Bending

Roll bending offers several advantages over other bending methods:

1. High Production Rates: Roll bending is a high-speed process that can produce long sections of formed shapes quickly and efficiently.

2. Consistent Quality: The use of opposing rolls ensures that the material is bent uniformly and consistently, resulting in high-quality formed shapes.

3. Versatility: Roll bending can be used to produce a wide range of formed shapes, including angles, channels, and curves.

4. Cost-Effective: Roll bending is a cost-effective method of producing formed shapes, as it requires minimal setup time and can be performed using standard tooling.

Conclusion

Roll bending is a continuous bending process that is used to produce long sections of formed shapes from coil or strip stock. It offers several advantages over other bending methods, including high production rates, consistent quality, versatility, and cost-effectiveness.
