Straightening Machine Main Unit

A straightening machine is equipment used to straighten metal profiles, bars, tubes, wires, and similar materials. It employs straightening rolls to apply pressure to bars and other materials, altering their straightness. Typically, it features two rows of straightening rolls, with the exact number varying. Two-roll straighteners also exist, utilizing two rollers (concave in the middle, hyperboloid rollers) whose angle changes to straighten materials of different diameters. Primary types include pressure straighteners, balanced roll straighteners, shoe roll straighteners, and rotary reverse-bend straighteners.
