The present invention relates to a large diameter wire coil winding device having a built-in wobble function, and more particularly, a large diameter built-in wobble function for winding a final hot rolled material into a cylindrical shape by receiving a tension of a pinch roll after water-cooling heat treatment. It relates to a wire coil winding device.

In general, as shown in Figure 1, in the large diameter wire production line is divided through a divert switch (Divert Switch) for dividing the rolled wire (1), the divided wire 1 is a pinch roll ( 3; Pinch Roll, and then through the first guide (4) and through the second guide (5) of the pre-bending machine on the rail (Rail) through the reel drum (6; It is wound up in a reeler drum.

As such, in the related art, the wire rod 1 is coiled and wound by the reeler drum 6 which is constantly rotated, and the coiling is wound by the inner reeler mandrel 7 in the circumferential direction, When the winding speed is increased, the winding is made to the outside of the reel drum 6, and there is no choice but to form a space inside and outside the coiling.

Therefore, in the case of small diameter production and high-speed rolling, the winding height is increased, and as shown in FIG. 2A, the coiling 11 at the rear end is raised above the height of the reel drum 6 before the winding is completed, thereby simultaneously stopping the production. In the case of small diameter production, when the pass is completed in the pinch roll, the ring is formed larger than the inner diameter of the reel drum 6 due to the effect of acceleration (Free Pass), so that a uniform ring is not formed. As shown in the figure, since it is wound in a crushed or largely formed state, when it protrudes (raises) upward from the reel drum by the conveying means, deflection of the rear end occurs from the pinch roll to the reel unit.

In addition, as shown in C shown in FIG. 2, in the case of large diameter production, the rear end portion deviated from the pinch roll is formed with less coiling due to the winding and the bending load, and the rear end end is formed in the second guide 5. As the phenomenon occurs, production is stopped.

And, as shown in Fig. 3A, the conventional small diameter coiling winding form is wound in a state in which a space is formed inside and outside of the reel drum 6, so that the winding height is increased, and the rear end ring sag. A phenomenon occurs, and as shown in B of FIG. 3, the arm of the transfer unit 15 which rotates and transfers the coil 14 wound in the reel drum in the direction of the conveyor in the same manner as described above. Obstacles of clamping and coiling on the chain conveyor wheels can cause the coil transfer equipment troubles and production operations to be stopped.

In addition, the wound coil, as shown in FIG. 3C, has a problem of overturning by shaking back and forth when transported to the chain conveyor and the roller conveyor 16, or transferred to the coil transport vehicle.

In order to solve the problems described above, the present invention distributes the coiling wound to the horizontal pinch roll device and the rear end immediately above the coil reel unit to the inside and outside of the reel drum and at the same time wobbling. ; Coiling size adjustment) to absorb the space between internal and external coiling to make the coiling height lower and at the same time to secure the coil production and winding so as not to be rolled over even when the coiling is held and transported during coiling.

It is synchronized with the rolling speed of (1), the operation of the upper vertical roller 44 is a repetitive operation to return to the inner side after a certain time after the expansion to the outer side.

That is, the speed of the linear reciprocating motion is increased because the speed is high in the case of small diameter production, and the number of repetitions is increased and reduced in the large diameter.

As described above, when the upper vertical roller 44 rotatably fastened to the circular sprocket 43 is rotated in a diagonal direction of the lower vertical roller 45, the wire rod 1 inserted is pinched secondarily, and the pinch is pinched. The strength is stronger as the production of small diameter and at the same time the ring diameter of the wire rod (1) formed when forming the ring in the reeler unit 100 to pass the material to pass through the wobble operation to adjust the number of rotational repetition, at the same time As shown in the cross-sectional view of the winding coil attached to FIG. 7 by distributing to the reel drum 101 side and the inner mandrel 102 side of the 100, the coiling is wound in an interconnected state inward, and thus the coiling thickness It prevents excessive space formation and of course lowers the winding height to guide the rear end ring inward to prevent sagging.

In addition, the scratching phenomenon caused by the shaking action that occurs when the drawn wire rod 1 is tensioned diagonally by the upper vertical roller 44 fastened to the pinch roller part 31 and the circular sprocket 43 so as to be rotatable. Absorption is prevented by a roller housing 24 composed of a plurality of pairs of upper and lower rollers.

On the other hand, when producing a coil of large diameter wire rod pinch roller portion 31 is pulled out by pulling the wire rod 1 in close proximity to the reeler portion 100 to form a small diameter ring of the rear end of the wire rod 1 due to the through load At the same time, the cylindrical guide 22 acts to escape safely, thereby improving the winding performance as well as preventing accidents during production. In this case, the upper vertical fastened so as to be rotatable to the circular sprocket 43. When the roller 44 is a coil production of a large diameter wire rod, the working distance is extended to only guide and guide the wire rod. In addition, as the outer winding form, the gap between the ring is absorbed by the winding tightly has the advantage that the shape is beautiful and easy to handle and transport.

The large diameter wire coil winding device having the wobble function according to the present invention reduces the passing load by tensioning the pinch roll to the upper end of the winding machine when the coiled coil is wound into a cylindrical shape by the winding machine. It is easy to wind up, and the winding is made in coiling size suitable for wire rod production size, which can increase the rolling speed, increase productivity and beautiful winding surface state, and prevent the rear end deflection phenomenon. It prevents equipment troubles and mass production of defective products and increases the error rate. Especially, the coil is not rolled over due to the shaking (shake) during the conveyance on the roller conveyor, and the coil is safely transported. The coiling size is uniform and the end is Safer production is achieved as well as the larger diameter coil winding state is improved because the guide is completed more safely.
