At this time, the straightening device is needed to correct it, so a steel-cored aluminum stranded wire straightening device is needed. When straightening the slightly bent steel-cored aluminum stranded wire in actual use, the external control box is used to start the heating plate 3 to preheat the protective box 1 and the feeding pipe 12. Then the slightly bent steel-cored aluminum stranded wire is put into the inside of the protective box 1 through the feeding pipe 12, so that it is located on the arc-shaped plate 2. The heat generated by the heating plate 3 can be transmitted into the steel-cored aluminum stranded wire through the arc-shaped plate 2 to heat it. The external control box is used to start the electric telescopic rod 7. The roller 9 is driven to move downward through the connecting frame 8. When the roller 9 contacts the steel-cored aluminum stranded wire, the electric telescopic rod 7 is turned off. Then the external control box is used to start the driving motor 4.
