roller straightener
Introduction
The roller straightener, or roller leveler, is a special device used in metalworking processes to straighten sheet, strip or wire with a flat or textured surface. It is designed to provide a uniform, precise flat to the sheet material, allowing it to fit any forms, dies or molds into welding, fabricating or industrial machinery applications. This article provides an overview of the operation of the roller straightener and the types of systems available.
Operation Principles
Roller straighteners are comprised of a horizontal or inclined roller conveyor and a series of in-line rollers that are adjusted to precise machine tolerances. A straightening plate is attached to the conveyor belt and the rollers. This plate is then adjusted and leveled to create a perfect straight surface. The rollers, which are set underneath the plate, are then driven along a precise path that corresponds to the desired plane of the surface.
As the material travels along the plane, the rollers provide a uniform pressure and contact area. This allows the material to be flattened to the exact plane desired. The precision and accuracy of the roller contact area, coupled with the exact plane of the surface, provides an outstanding straightening solution for a wide range of materials.
Systems Available
The most common type of roller straightener is a three-roller system. The three rollers are arranged in a triangle and connected to the conveyor. Two rollers are driven by a motor, which provides a perfect and precise path for the material. The third roller is called a “drive roller”, and this is used to steer the material along its predetermined plane.
There are also two-roller systems available where the rollers are arranged in a straight line. The two rollers are driven together and the drive roller is used to steer the material along its predetermined plane.
The main advantage of the three-roller system is that it provides better precision and accuracy than the two-roller system. This is because the three rollers are able to provide an even distribution of force, which ensures that the material is flat across the entire plane.
Conclusion
Roller straightener systems provide an ideal straightening solution for a wide range of materials. By combining a precise conveyor belt along with adjustable in-line rollers, they are able to deliver the exact plane required. This accuracy and precision is especially necessary in the fields of welding and fabricating, where exact planes are required to ensure the quality of the finished product. Two and three-roller systems are available to provide additional parameters for creating the perfect flat surface.
