Wire drawing device

A wire drawing device includes a first wire drawing mechanism, a second wire drawing mechanism and a roller, wherein the first wire drawing mechanism and the second wire drawing mechanism are arranged in parallel, the roller is driven by a motor, a first wire drawing die is arranged on the first wire drawing mechanism, a second wire drawing die is arranged on the second wire drawing mechanism, a vertical support plate is also arranged in front of the first wire drawing mechanism and the second wire drawing mechanism, a steel bar surface preprocessing mechanism is arranged on one side of the vertical support plate, a reverse wheel is arranged on the other side of the vertical support plate, a wheel shaft of the reverse wheel is fixedly arranged on the vertical support plate, a support rod is connected onto the wheel shaft, the other end of the support rod is fixed on the vertical support plate, and a first winding part and a second winding part are arranged on the roller and used for the winding of a steel bar. The steel bar sent from a rolling wheel system is wound around the first winding part after passing the first wire drawing die of the first wire drawing mechanism, enters the second wire drawing die of the second wire drawing mechanism through secondary reversing of the reverse wheel for wire drawing diameter reduction, and is wound around the second winding part of the roller, so as to achieve double steel bar wire drawing procedures.
