The invention discloses a servo drive traction machine. The servo drive traction machine comprises a machine frame, an electric box, an operation box and a transmission mechanism, wherein the electricbox is arranged on the machine frame. The transmission mechanism comprises a linear polish rod, a screw rod, an opening and closing servo motor, an upper side traction device, a lower side traction device, a driving servo motor and a reduction gearbox, wherein the linear polish rod is connected with the upper side traction device and the lower side traction device through a linear bearing, the opening and closing servo motor is connected with the screw rod, the lower side traction device and the lower side traction device are installed on the side part of the screw rod through a nut and a nutseat, an air cylinder is further connected between the lower side traction device and the nut seat, and the air cylinder is driven by the opening and closing servo motor to provide the transaction opening and closing power for the upper side traction device and the lower side traction device. A belt pulley of the upper side traction device and a belt pulley of the lower side traction device provide the driving power by the driving servo motor and the reduction gearbox, the belt pulleys drive belts to carry out traction, and guide mechanisms are further arranged at the two ends of the upper side traction device and the lower side traction device. According to the servo drive traction machine, the clamping pressure is conveniently adjusted, the constant clamping force can be provided, and the stable wire production speed can be provided.
