The special-shaped steel wire can meet the quality requirement and performance requirement of a user on the steel wire, has wide application, and mainly comprises a mechanical processing industry, a textile industry, a sealing steel wire rope, a structural steel wire, a nail making steel wire and the like. For example, profiled metal wires are currently mainly achieved in two ways, one is profiled die drawing and the other is passive profiled roll rolling. Both the forming modes require the traction machine to provide power, and the power is transmitted to the belt pulley, the belt to the speed reducer to the transmission shaft to the traction roller through the motor of the traction machine to finally drive the special-shaped metal wire.
