Description

Guiding apparatus of winding spiral coil ring for wire rod-coil}

The present invention relates to a coiling and winding induction device in a reforming tube end of a wire coil conveying conveyor. More particularly, the final rolled hot ball wire is formed by spiral coiling through a winding hade. The present invention relates to an induction apparatus for winding a reforming tube, in which coils are heat-treated in various ways according to product size and steel grade, and then integrated when rolled to a roll conveyor installed in a long distance.

In general, the coil falling into the reforming tube is inclined to fall due to the change in the center of gravity when the coil is dropped into various shapes such as the coil shape, the drop speed, the coil surface temperature, the elongation rate, and the drop coil amount (transfer coil thickness) according to the heat treatment method. The shape was uneven and accompanied by friction defects on the coil and on the outer surface. As a result, the coils on the roller conveyor, which were transported continuously and interrupted production due to the progress of the post-processing, were treated as defective.

In general, the wire coil transfer line as shown in FIG. 1 is formed of a spiral coil (3) through the winding machine (2) of the final rolled hot linear shape in the cooling pattern (pattern) by product size and steel type During the heat treatment, the conveyor roller 4 is transferred to the reform tube 6 and finally integrated.

At this time, the coiling ring 3, which is out of the end feed roller 41, falls down obliquely to the loss of weight balance when falling into the reforming tube cone 5, and is accompanied by a collecting plate 7) Winding was inclined at the top, and friction defects occurred on the inner surface of the winding coil. In addition, the tip ring deflected between the tip feed roller 41 and the cone 5, causing a total feed failure due to the tip ring entry failure.

On the other hand, when the rear end coiling is formed slightly larger or the ring shape is poorly entered during conveyance of the conveyor roller, it is not transported to the cone due to bilateral side wall entry obstacle and at the same time overlaps with the continuous coiling, it is impossible to proceed with the post process. The production stoppage and defective products were mass produced. Therefore, in this case, the coiling was manually pulled up to the cone and integrated.

The conventional hot coil winding process loses the center of gravity between the rings (3) when the coil ring (3) coming out of the end roller (41) enters the cone (5) and falls to the mandrel (8) in an inclined state. By winding up to the collecting plate 7 in a state where the inclination is gradually increased, the entire winding coil is inevitably formed, which causes friction defects to occur inside the coil ring 3 and the coil. There was a problem that the winding state of the ring is changed to a staircase, so that the transfer process becomes difficult or a production disruption occurs.

Therefore, in order to fundamentally eliminate the above-mentioned problems, the winding forming state of the coil ring falling into the reforming tube is uniformly and lowly formed in the horizontal state with the cone regardless of the heat treatment process and the production conditions, as well as occurring during the coil contact. It is an object of the present invention to provide a spiral coil ring winding induction apparatus of a wire rod coil which prevents a friction defect and at the same time avoids an inclined winding shape and allows a post process to be performed more safely.

Referring to FIG. 2, a space is formed so that two axes composed of a coaxial shaft sprocket 14 and a driven shaft sprocket 15 can rotate in a direction perpendicular to the upper end of the end feed roller 41 of the coil integrated reforming tube. It consists of a base (16) coupled and supported according to the connection and the two shafts are connected by a cam rod (17) formed in a curved shape in a circumferential surface in a state of being perpendicular to the top of the driven shaft rotation center axis and the end roller center do.

The solenoid valve 191 sets the upper and lower operating speeds and the coil holding pressures of the connecting rods connected by the high information bolts 201 to the center of gravity of the base 16 connecting the two shafts according to the pneumatic set value of the pneumatic cylinder 19. And the pneumatic cylinder 19 itself can also be configured to flow according to its inclination.

In addition, to the pneumatic set value of the solenoid valve of the solenoid 191 valve of the pneumatic cylinder 19 in a state coincided with the weight of the entire base 16 including the center of gravity 18 and the circular, driven shaft sprockets (14, 15). Accordingly, the connection table 20 is provided with a shock protector 22 to relieve the shock when the operation while pressing the crimp while holding the coil. The shock absorbing force of the shock absorber is configured to be adjusted by the compression spring 222 and the rod up and down adjustment bolt 223, the nut 224 inserted into the pedestal rod 221.

Figure 3 shows the operating state of one embodiment of the coiling winding induction device of the present invention. Referring to FIG. 3, when the coil ring 3 formed of the spiral coil in the winder 2 is transferred to the conveyor roller 4 over a long distance, it undergoes a heat treatment process for each product size and steel type. Different types of coil rings are transferred to the end rollers 41 due to differences in the thickness of the transfer coil, the latent heat of the coil, the elongation, the elastic difference, the size and shape of the coil ring, and the feed rate for each heat treatment process.

The coiling conveyed to the end roller 41 has the appropriate pressure under the control of the pneumatic cylinder solenoid valve 191 of the same speed and the appropriate pressure of the cam rod 17 connected by the circular and driven shaft sprocket wheels 14 and 15.
