Purpose

The machine is arranged by four sets of straightening rollers, and one guide roller is arranged reasonably. The drive type is eight-roll full drive, the feeding type is left-to-right and the drive frame type is left-high and right-low (The distinction between left and right is determined by person facing the front of straightening machine) and the motor is driven by a special reducer, the universal joint is rotated, the torque is large, and the structure is reasonable and reliable. It is used for straightening black and non-ferrous metal type tube/bar. Ideal equipment, used for straightening Φ15 ~ Φ45 bar. When the tube /bar is "bitten" by the roller, as the roller rotates forward, due to the inclined layout of the rollers, after repeated rotation and curvature, The cross-section of the bar is subjected to elastic-plastic bending for many times in the process of rotating and going forward, Finally, the reverse straightening is obtained over the entire length.
