Simultaneously with this rolling process, a feed force is applied to the wire rod (W). To this end, the inclination of the first roll dice 460 and the second roll dice 470 is appropriately set according to the material and the feeding speed of the wire rod W. As the inclination increases, the feeding speed becomes faster. In fact, as shown in FIG. 10, the inclination θ of the first roll dice 460 installed in the first block 440 is preferably set in a range of 1 to 10 ° in consideration of a feed speed and the like.

First, as shown in FIGS. 2 and 3, as the driving motor 251 of the drawing apparatus 200 is driven, the first pulley 230 and the second pulley 240 are simultaneously rotated. Therefore, due to the tensile force generated while the first pulley 230 and the second pulley 240 rotate, the wire W wound around the idle bobbin 100 exits the drawing die 210 while reducing its diameter and overall. Surface becomes uniform. At this time, since the oil 214 is stored in the drawing die 210, the surface roughness of the wire rod W is improved, as well as the gloss.

When entering through the treated end), 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 alternately with each other, as shown in FIG. 10, 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.

An upper punch 627 is mounted below the side of the movable member 629, and a lower die 628 is mounted above the side of the lower frame 622 corresponding to the upper punch 627. Accordingly, the wire W positioned on the lower die 628 is cut by the upper punch 627 during the momentary lowering operation of the movable member 629.

And the driving means 650 as described above, for moving the cutter 620 at the same speed as the feed rate of the wire rod (W), the power of which is transmitted through the reducer 322 of the calibration device 300. It is configured to receive.

That is, as shown in FIGS. 13 and 14, the power of the drive motor 331 (see FIG. 5) input to the speed reducer 322 of the calibration device 300, the input shaft 340, passes through the gear train, and outputs the shaft 350. The camshaft 652 in which the cam 651 is mounted coaxially with this output shaft 350 is provided. The circumferential surface of the cam 651 contacts the roller 654 formed at the tip of the piston rod 653 to move the piston rod 653 in the horizontal direction. The drive cylinder 655 in which the piston rod 653 is incorporated is fixed to the side of the reducer 332, and hoses 661 and 662 are coupled to both sides of the drive cylinder 655 to form a flow path.

In addition, a driven cylinder 670 is fixedly installed to the side of the cutting machine 620, and the tip of the piston rod 671 built into the driven cylinder 670 is coupled to the side of the lower frame 622, and this driven The hoses 661 and 662 are connected to both sides of the cylinder 670, respectively, so that flow paths associated with the driving cylinder 655 are formed.

Therefore, when the driving motor 331 of the calibration device 300 is driven to rotate the cam 651 together with the cam shaft 652 of the reduction gear 322, the cam 651 may be driven by the eccentricity of the driving cylinder 655. The piston rod 653 is moved to the top dead center so that the oil on the piston side is introduced into the piston side of the driven cylinder 670 through the hoses 661 and 662. Thus, as shown in FIG. 15, the piston rod 671 of the driven cylinder 670 is pushed out, whereby the cutter 620 is transferred along the guide rail 610 in the arrow X direction.

On the other hand, when the cam 651 rotates, the circumferential speed of this cam 651 is transmitted to the piston rod 653 of the drive cylinder 655 in which the roller 654 is provided at the front end as it is, and this piston rod 653 The conveying speed (linear speed) is again transmitted to the piston rod 671 of the driven cylinder 670 through the pressure oil, the conveying speed (linear speed) of the piston rod 671 is transmitted to the cutter 620. Similarly, the output shaft 350 is provided coaxially with the cam shaft 652, and the correction rolls 311 and 312 are rotated by the universal joint 333 to the output shaft 350, thereby correcting the correction rolls 311 ( The circumferential velocities of 312 and the linear velocities of the wire (W) calibrated through them coincide. As a result, the linear speed at which the wire rod W is transported coincides with the linear speed at which the cutter 620 is transported. At this time, after determining the cutting length corresponding to the circumferential length of the straightening rolls 311 and 312 and the 1/2 rotation of the cam 651, the cutting machine 620 may be brought to the cutting position while the cutting machine 620 is transferred. Only when cutting the wire (W) by operating the cutter 620, the wire (W) can be cut to a predetermined length while being transferred to the cutter 620 while simultaneously correcting and hardening the wire (W).

In addition, the cutter 620 should return to the starting position while the cam 651 rotates the other half after cutting the wire W. FIG. To this end, as shown in Figure 13 and 14, the pneumatic cylinder 680 is coupled to the upper side of the base combined rolling oil tank 690 to the side of the cutter 620, the piston built in the pneumatic cylinder 680 The tip of the rod 681 is coupled to the side of the lower frame 622, and hoses 682 and 683 are connected to both sides of the pneumatic cylinder 680, respectively, and the piston rods 682 and 683 are piston rods. A flow regulating valve (not shown) for regulating the speed of 681 is provided.

In addition, the cutter 620 is to be returned to the initial position by the pneumatic cylinder 680 installed on the side after cutting the wire (W) in the cutting position, the cutting position and the initial position of the cutter 620 is the wire (W) It is preferable to comprise so that adjustment is possible according to the cutting length of). In addition, electrical control is possible by installing a sensor such as a limit switch or a proximity switch at each position.

Therefore, if the cams 651 connected to the cam shaft 652 of the reducer 332 rotates at the same time as the straightening rolls 311 and 312 of the straightening device 300 rotate constantly, the cutter 620 is in the cutting position. Move to and cut the wire (W). Subsequently, while the wire rod W is hardened, the cutter 620 is returned to the initial position.

As such, the wire rod W is non-stop cut to a predetermined length while being hardened while the cutter 620 is continuously moved left and right, thereby greatly improving its work productivity.

In addition, as illustrated in FIG. 16, the winding device 700 may be disposed to form one line behind the rolling curing apparatus 400, that is, the outlet side. Accordingly, the wire rod (W) exiting while being cured is temporarily wound by being wound on the bobbin 710 of the winding apparatus 700 and may be cut and used to an appropriate length according to the demand of the consumer. In addition, between the curing device 400 and the winding device 700 by installing a bending roll 720 for bending the wire rod (W) coming out of the cured to a predetermined curvature, so that the winding operation of the wire (W) can be easily made It is desirable to.

In addition, the present invention was applied to the processing of the wire (W) having a circular cross section as an example, but the present invention may be applied to the processing of a hollow tube material without being limited thereto, and the rolling curing apparatus 400 in series You can also place it.

As described in detail above; According to the wire rod processing system according to the present invention, a drawing device for drawing the wire rod to have a predetermined diameter, a straightening device for calibrating the drawn wire rod, and a curing device for rolling cured wire rod to form a single line sequentially It is arranged. As a result, the wire wound on the idle bobbin is automatically transferred to the rear as it is continuously processed through the drawing device → straightening device → hardening device, thereby rolling wire hardening continuously and thereby increasing work productivity significantly. There is a working effect. In addition, the hardness and surface gloss of the wire is significantly improved, and the linearity and precision of the wire are also increased.
