The invention discloses a prestressed steel stranded wire drawing head. The prestressed steel stranded wire drawing head comprises a first flange and first locating plugs, first fixed holes are formed in the outer edge of the first flange, a body is fixedly arranged at the right side of the first flange, a second flange is installed at the right end of the body, second fixed holes are formed in the outer edge of the second flange, a drawing head body is fixedly arrange at the right side of the second flange, first locating plates are connected to the outer sides of the first locating plugs, connecting rods are fixedly arranged at the right sides of the first locating plates, second locating plates are installed at the right ends of the connecting rods, second locating plugs are fixedly arranged among the second locating plates, and a wire inlet is formed in the inner side of the drawing head. The first locating plugs, the first locating plates, the second locating plugs and the second locating plates are arranged in the prestressed steel stranded wire drawing head, the occurrence of a phenomenon that a prestressed steel stranded wire is drawn and loosen can be prevented, and through cooperative work of the second locating plates and the wire inlet, the phenomenon that the prestressed steel stranded wires wind and cross in the device is effectively prevented from occurring.
