That is, as shown in FIGS. 4 to 8, the wire rod W exiting the straight jig 220 of the calibration device 200 while being calibrated is the first roll die 460 and the second roll of the hardening device 400. When entering through the processed ends of the crowning 462 and 472 of the die 470, the wire rod W exits while rubbing against the outer circumference of the first roll die 460 and the second roll die 470. Therefore, the surface of the wire W is smoothly plasticized by the frictional pressure of the first roll die 460 and the second roll die 470, whereby the surface gloss thereof is significantly improved. In addition, the surface of the wire (W) is work hardened to improve the fatigue strength.

In addition, since the first roll dice 460 and the second roll dice 470 rotate in a state in which they are inclined to shift from each other, as shown in FIG. 8, the load F transmitted from these to the surface of the wire rod W is shown. ) Is separated into a feed force f2 and a contact load f1 to impart a feed force to the processed wire rod W. Accordingly, the wire (W) is automatically discharged to the rear through the guide bush 431 while the surface is continuously rolling and the surface gloss is significantly improved while its straightness and precision are also increased.

Therefore, in the wire processing system according to the present invention, the straightening device 200 for calibrating the wire (W) wound on the idle bobbin 100 and the hardening device 400 for curing the calibrated wire (W) is one line They are arranged sequentially so that their work productivity is greatly improved.
