This patent discloses a triangular plane straightening wire machine, comprising a triangular wire drawing machine and a round tube straightening auxiliary machine mounted on the triangular wire drawing machine. The triangular wire drawing machine includes a frame, with a driving wheel, driven wheel A, and driven wheel B mounted on the upper end of the frame. The driving wheel, driven wheel A, and driven wheel B are arranged in an isosceles triangle on the upper end of the frame. A worktable is mounted at the lower end of the sanding belt, and a lifting frame is mounted at the lower end. Vertically arranged bushings are mounted on both sides of the lifting frame. The corresponding lifting guide shafts are vertically arranged and installed on both sides of the frame. The upper end of the lifting frame is equipped with a lifting rotating shaft arranged in the X-axis direction. Lifting gears are installed at both ends of the lifting rotating shaft. The lifting racks corresponding to the lifting gears are vertically arranged and installed on both sides of the frame.
