Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a conveyor system for uniformly cooling a wire,

The present invention is a technical field of a conveyor system for achieving uniform cooling of a wire rod.

Stelmor method is used as a general cooling method of wire rod.

1 is a side view and a plan view showing a conventional conveyor system for conveying a wire using the Stelmore method.

A wire rod of 850 degrees or 900 degrees is wound in a coil form using a winding machine and then conveyed to a conveyor as shown in Fig.

The wire rod 1 is dropped from the take-up machine to the conveyor, and then conveyed in the form of a series loop by the conveyance of the conveyor. The wire rod 1 is then cooled during the conveying of the conveyor. When cooling is finished, the wire rod 1 is vertically moved directly to the next stage.

When it is necessary to cool the wire 1 faster, forced air cooling is performed through the blower 30 provided at the lower part of the conveyor. If it is necessary to cool the wire 1, a slow cooling cover is placed on the conveyor to delay heat radiation.

The stellum method has excellent productivity, but due to the nature of the series loop shape, the wire 1 overlaps the outer periphery side, and the cooling is slower than the inner periphery portion, resulting in a stiffness variation. Fig. 2 is a graph showing the overlap density of the wire 1 along the width direction of the wire 1 when the conventional conveyor system shown in Fig. 1 is used.

Even if a technique of concentrating the blowing amount of the blower 30 by dividing the blowing amount of the blower 30 and lowering the blowing amount of the inner blowing portion to uniformly cool the wire rod 1 is used, the overlapping density of the outer blowing portion is very high, Could not avoid quality defects.

In order to solve this problem, there has been a method of lowering the overlapping density of the outer periphery by providing a side guide. However, there is a problem that the effect is insufficient or extremely low due to the degree of change in the overlap density of the outer periphery.

A conveyor system for uniformly cooling a wire rod according to the present invention has been devised in order to solve the above-mentioned problems of the related art, and it is intended to provide a conveyor system capable of uniformly cooling the wire rod in the process of naturally cooling the conveyor during conveyance .

A conveyor system for uniform cooling of wire rod according to the present invention comprises a first conveyor part (102); And a second conveyor section (103).

First, as shown in FIG. 3, the wire rod 1 fed through the conveyor 101 has a larger density of overlapping outer portions than inner portions. Therefore, if the traveling direction of these conveyors 101 is changed and the portions where the wire rods 1 are overlapped by the changed angles are changed, the cooling rate of the wire rods 1 is uniformly progressed.

First, the first conveyor unit 102 forms a predetermined first angle from the traveling direction of the present conveyor 101 and bypasses the wire material 1 from the present conveyor 101.

The second conveyor portion 103 is configured to again bypass the first conveyor portion 102 from the first conveyor portion 102 so as to form a predetermined second angle, So that the cooling along the width direction of the wire rod 1 is made uniform.

As shown in FIG. 3, the conveyor area for bypassing may have three, in which case it may further include a third conveyor part 104.

The third conveyor part 104 makes a predetermined third angle from the second conveyor part 103 to bypass the wire material 1 from the second conveyor part 103 and then finally to the third conveyor part 104 are configured to return to the main conveyor 105.

These conveyor sections 102, 103 and 104 are preferably acute angles of not more than 90 degrees, more preferably not less than 30 degrees and not more than 90 degrees, respectively, for a predetermined angle, a second angle and a third angle Was evaluated as an optimum embodiment.

When these predetermined first to third angles are obtuse angles, it is not preferable since the phenomenon that the wire rods 1 to be conveyed along them are not smoothly moved outward often occurs.

Fig. 3 shows these angles at 90 degrees, and Fig. 6 shows the phenomenon that the overlapping phenomenon of these wire rods 1 is changed.

6, the wire member 1 conveyed through the conveyor 101 has a high overlapping density at the B site. The temperature at the B site is relatively high, and the overlapping density of the wire members 1 at the A site is relatively high And the natural cooling is smooth and the temperature tends to be low.

Thereafter, when moved to the first conveyor part 102, the overlapping density of the B part is increased and the overlap density of the A part is lowered in the wire 1 in the first conveyor part 102, The first conveyor unit 102 is moved to the B position.

This process occurs again from the first conveyor portion 102 to the second conveyor portion 103 and proceeds from the second conveyor portion 103 to the third conveyor portion 104 and the third conveyor portion 104 to the conveyor 105, the natural cooling of the wire rod 1 in the width direction is uniformly performed.

In the bypassing process, it is preferable that the wire rod 1 is dropped, and it is preferable to provide the dropping portion 110.

The dropping unit 110 is located at the end of each of the conveyors 101, 102, 103 and 104 so that the dropping unit 110 passes vertically through the conveying unit 101 and vertically drops the conveyed wire 1.

4, when the first conveyor part 102 and the second conveyor part 103 are conveyed from the first conveyor part 102 to the second conveyor part 103, The wire rods 1 which are reached first are influenced by the proceeding wire rods 1 due to the following wire rope 1 and the wire rods 1 are irregularly rotated or the wire rods 1 It is preferable to drop it.

The wire rod 1 dropped from the first conveyor portion 102 is not rotated but dropped to the succeeding second conveyor portion 103 as shown in FIG. 1) is excellently influenced by the subsequently arriving wire (1).

As shown in FIG. 5, the dropping unit 110 includes a backing plate 111; And a focusing unit 112.

The backing plate 111 is a plate for preventing the wire member 1 from horizontally moving and preventing the wire member 1 from jumping out in the advancing direction due to the speed (inertia) at which the wire member 1 is fed at the end of the conveyor.

A lower end of the backing plate 111 is provided with a focusing unit 112. The lower end of the backing plate 111 is formed into a cylindrical shape so that the wire 1 can be seated at a desired position, ) To the subsequent conveyor accurately.

By dispersing the concentration phenomenon of the overlapping density of the outer periphery of the wire rod 1 by the present invention as described above, the deviation of the temperature of the wire rod 1 is improved as shown in Fig. 7, resulting in a uniform characteristic , And the finally produced quality of the wire rod 1 is also improved.
