The invention discloses a steel wire manufacturing production line. The steel wire manufacturing production line comprises a wire pay-off device, a steel wire lead-out device, a steel wire straightening device, a steel wire grinding device, a steel wire surface dust processing device, a water washing device, a drying device and a wire collection device. The wire pay-off device comprises a base, a bottom plate used for fixing a steel wire fixing frame is arranged on the base, one side of the bottom plate is hinged to the base, the lower end of the bottom plate is fixed to an air cylinder on the base, a fixing shaft is arranged in the center of the upper end of the bottom plate, the bottom of the steel wire fixing frame is fixed to the fixing shaft through a bearing, a steel wire supporting frame is arranged between the steel wire lead-out device and the steel wire straightening device, a fixed guide wheel and a movable guide wheel are arranged on the steel wire supporting frame, the water washing device is connected with the drying device, and a waste water collecting tank is arranged between the water washing device and the drying device. The steel wire manufacturing production line is simple in structure and reasonable in design, a steel wire can be straightened and ground, meanwhile, the occupied area can be reduced, and the content of the dust in air can be effectively reduced.
