Curvature non-scratching straightening device for copper clad steel bar and the like

A curvature non-scratching straightening device for a copper clad steel bar and the like comprises a machine box, a feeding mechanism, a drawing mechanism and a roller gap adjusting mechanism. The feeding mechanism is arranged at the feeding end of the machine box, and the feeding mechanism is driven by a motor on the machine box. The feeding mechanism is further provided with the roller gap adjusting mechanism. The drawing mechanism is arranged at the discharging end of the machine box, is driven by a motor in the machine box and is still provided with the roller gap adjusting mechanism. The machine box is provided with a lubricating system, and a rotation stopping mechanism corresponding to the discharging end of the feeding mechanism is arranged beside the feeding mechanism. A rolling die straightening mechanism corresponding to the discharging end of the rotation stopping mechanism is arranged beside the rotation stopping mechanism, and the discharging end of the rolling die straightening mechanism corresponds to the discharging end of the drawing mechanism. The rolling die straightening mechanism is driven by the motor on the machine box. Compared with the prior art, the curvature non-scratching straightening device has the advantages of being capable of achieving non-scratching straightening, high in straightening precision, good in straightening effect and the like.
