A roller straightener for metal parts is a type of equipment used to straighten and align metal components that have become bent or distorted. It is commonly used in industries such as automotive, manufacturing, and metal fabrication.

The roller straightener consists of a series of rollers arranged in a specific pattern or configuration. The metal part is fed through the rollers, which apply pressure and force to reshape and straighten the component. The rollers can be adjusted to different positions and angles to target specific areas of the metal part that require straightening.

The process of using a roller straightener involves carefully feeding the metal part through the rollers, making incremental adjustments to gradually straighten the component. It requires skill and precision to ensure that the metal part is straightened without causing further damage or distortion.

Roller straighteners for metal parts can be manually operated or automated, depending on the complexity and size of the metal components being straightened. They are often used in conjunction with other metalworking processes, such as bending, forming, or welding, to achieve the desired shape and alignment of the metal parts.
