PURPOSE: A wire rod working system is provided to improve working productivity of the wire rod by in-lining drawing process of a wire rod, correction and cutting processes of the wire rod, and hardening process of hardening the cut wire rod, thereby continuously working the wire rod. CONSTITUTION: In a wire rod working system comprising a drawing unit(200) for drawing a wire rod (W) coiled on an idle bobbin(100) so that the drawn wire rod has a certain diameter, a correction unit(300) for correcting the drawn wire rod (W), a cutting unit(400) for cutting the corrected wire rod (W), and a hardening unit(500) for hardening the cut wire rod (W), the wire rod working system is characterized in that the drawing unit(200) is equipped with a drawing dies(210) for reducing diameter of the wire rod (W) that is being uncoiled from the idle bobbin(100), and a pulley block(220) which is arranged at the exit side of the drawing dies(210) and driven in the state that a part of the wire rod (W) is coiled on the pulley block(220) so as to pull the wire rod (W) from the drawing dies(210), thereby draw the wire rod, the correction unit(300) comprises correction parts(310,320) which are arranged at the rear side of the pulley block(220) and correct vertical and horizontal bending of the wire rod that is coming out of the pulley block(220) as it is being uncoiled from the pulley block(220), the cutting unit(400) is equipped with a cutter which is arranged at the exit side of the correction unit(300) so that the cutter is horizontally moved, and which cuts the wire rod (W) to a certain length as the cutter is being synchronized with speed of the wire rod that is coming out of the correction unit(300) after it is corrected in the correction unit(300), and the hardening unit(500) comprises a frame, first head stock, first roll dies, second head stock, second roll dies, and a supporting blade.
