Description

The present invention relates to a wire coil cooling device capable of more uniformly cooling the wire coil.

Conventionally, Patent Documents 1 and 2 are known regarding the handling of a wire rod coil in which a wire rod such as carbon steel or stainless steel is wound in a direction orthogonal to the winding direction.

The "wire coil" of Patent Document 1 is a wire coil in which binding hoops are wound at a plurality of locations in the wire winding direction in a direction orthogonal to the wire winding direction, and the width of the wire coil is widened at a body portion of the wire coil. It is configured by winding a body-wound hoop that has a certain band shape and is softer than an iron wire in the winding direction of the wire rod and also intersects with the binding hoop.

In Patent Document 2, "a method for cooling a wire rod coil and a cooling device", the wire rod coil is placed in a storage place, and one end of a hollow portion of the wire rod coil is closed with a closing plate. By blowing air into the other end of the cavity by a blower, each part of the wire coil can be cooled uniformly and rapidly. In this way, the cooling rate of each part of the wire rod coil between 600 ° C. and 200 ° C. is set to 16 ° C./min or more for cooling.

In the cooling device of Patent Document 2, one end of the hollow portion of the wire rod coil is closed with a closing plate, and air is blown from the other end side of the hollow portion to cool the wire rod coil.

Therefore, the air blown from the other end side of the cavity portion flows toward the closing plate, the straight direction is blocked by the closing plate, and the air spreads in the circumferential direction on one end side of the cavity portion of the wire rod coil.

As a result, the dynamic pressure of air becomes higher in the vicinity of one end side closed by the closing plate than in the other end side of the cavity portion of the wire rod coil into which air is blown.

Therefore, there is a problem that the amount of air passing between the wire rods becomes significantly larger in the vicinity of one end side than the other end side of the cavity portion, and the wire rod coil cannot be cooled uniformly.

The present invention has been devised in view of the above-mentioned conventional problems, and an object of the present invention is to provide a wire coil cooling device capable of more uniformly cooling the wire coil.

The wire rod coil cooling device according to the present invention is provided on one side of the wire rod coil in the penetrating direction, a covering member covering the wire rod coil, and the other side of the wire rod coil in the penetrating direction. The cover member has a blower hole for blowing air toward the cover member side, and the cover member includes a protrusion inserted inside the wire rod coil, and the wire rod coil and the outer peripheral surface of the protrusion portion. A space is provided between them, and a suspension support is further provided with the covering member. The suspension support is provided from a suspension support portion suspended from above and a suspension support portion suspended from the suspension support portion. provided vertically, characterized in that it comprises a guide portion for guiding the vertical movement of the cover member is brought into contact with the wire coil.

The suspension support portion is characterized in that it is suspended by a suspension member via a pulley arranged above.

The covering member is characterized in that a cushion material is provided at a portion facing the wire rod coil. The cushion material is characterized by being a copper wire mesh.

In the wire rod coil cooling device according to the present invention, the wire rod coil can be cooled more uniformly. Further, since the covering member moves in the vertical direction by being guided by the hanging guide portion suspended from the hanging support portion suspended from above, the covering member is closed by the covering member, for example, because the number of stacked wire coil coils is different. Even if the position (height) changes, troubles in the hanging operation can be eliminated.

It is a vertical cross-sectional view which shows the modification of the cooling device of the wire rod coil shown in FIG.

Hereinafter, a preferred embodiment of the wire coil cooling device according to the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, the wire rod coil cooling device (hereinafter referred to as a cooling device) 1 according to the present embodiment winds the wire rod 2a in a cylindrical shape, and winds the wound wire rod 2a at a plurality of locations in the circumferential direction. It is a device for cooling the wire rod coil 2 configured by bundling with a band or the like.

The inside of the wire rod coil 2 formed in a cylindrical shape has a hollow portion 2b in the penetrating direction (axial direction).

As shown in FIGS. 1 and 2, the cooling device 1 includes a mounting table 3 on which the wire rod coil 2 is mounted, a hanging support 4 suspended above the mounting table 3, and a hanging support 4. The cover member 5 is provided so as to be movable in the vertical direction. The covering member 5 is guided to move in the vertical direction by the hanging support 4.

The mounting table 3 is formed, for example, in a rectangular shape in a plane, and includes a top plate 3a on which the wire rod coil 2 is mounted. In the center of the upper surface plate 3a, a blower hole 3b having a hole diameter smaller than the inner diameter of the wire rod coil 2 to be mounted is provided.

The blower hole 3b is located on the lower end 2d side of the wire rod coil 2 in the penetrating direction of the wire rod coil 2 mounted on the mounting table 3.

Air supplied from a blower (not shown) is blown upward from the blower hole 3b. That is, the air is blown toward the covering member 5 side into the hollow portion 2b of the wire rod coil 2 placed on the upper surface plate 3a.

Here, instead of the mounting table 3, a roller or a chain conveyor can be used to sequentially carry in and out the wire rod coil 2. In that case, a roller or a chain is arranged so as to avoid the upper part of the ventilation hole 3b so that ventilation can be secured.

The suspension support 4 includes a suspension top plate 7 as a suspension support portion suspended from above by a wire 6 or the like, and a plurality of rods 8 as a guide portion suspended from the lower surface 7a of the suspension top plate 7. And have.

The hanging top plate 7 is suspended by a wire 6 as a hanging member via a pulley 12 arranged above. The wire 6 is turned around by the pulley 12 and is wound up and down by the winch 13 provided on the side. A chain may be used instead of the wire 6, and in this case a sprocket is used instead of the pulley 12.

The hanging top plate 7 is formed, for example, in a rectangular shape in a plane, and is suspended so as to face the upper surface plate 3a at intervals in the vertical direction.

The rod 8 has a columnar shape and is vertically hung at each of the four corners of the hanging top plate 7. The rod 8 is slidably inserted into the covering member 5, whereby the covering member 5 is guided by the rod 8 and can move in the vertical direction.

At the lower end of the rod 8, a stopper 8a for restricting the downward movement of the covering member 5 is provided.

The covering member 5 includes a covering plate 9 formed in a rectangular shape having substantially the same plane as the hanging top plate 7, and a columnar protrusion 10 provided in the center of the lower surface 9a of the covering plate 9 so as to project downward. A cushioning material 11 provided on the lower surface 9a of the covering plate 9 is provided.

Insertion holes 9b through which the rod 8 of the suspension support 4 is inserted are provided at the four corners of the cover plate 9.

The protrusion 10 is formed with an outer diameter smaller than the inner diameter of the wire rod coil 2. By inserting the protrusion 10 inside the wire coil 2 mounted on the mounting table 3, the lower surface 10a of the protrusion 10 is a top plate in a state where the covering member 5 is mounted on the wire coil 2. It is formed so as to be located above 3a.

The outer peripheral surface 10b of the protrusion 10 inserted inside the wire rod coil 2 is spaced apart from the wire rod 2a on the inner peripheral side of the wire rod coil 2. That is, a gap S is provided between the wire rod coil 2 into which the protrusion 10 is inserted and the outer peripheral surface 10b of the protrusion 10.

The cushion material 11 is provided at a portion facing the wire rod coil 2 except for the protrusion 10 on the lower surface 9a of the covering plate 9.

The cushion material 11 is formed by stacking, for example, a plurality of copper net materials. The cushion material 11 may be an elastic member having heat resistance. As a result, it is possible to prevent the surface of the upper end 2c of the wire rod coil 2 from being scratched by the vibration of the cover plate 9 when the air is blown.

In the cooling device 1, when the wire coil 2 is not mounted on the mounting table 3, the covering plate 9 is located on the lower end side of the rod 8 due to its own weight, and hits the stopper 8a, as shown in FIG. I'm in contact.

When the wire rod coil 2 is cooled by the cooling device 1, as shown in FIG. 1, the wire rod coil 2 is placed on the upper surface plate 3a of the mounting table 3 and arranged under the cover plate 9 of the covering member 5.

At this time, the blower holes 3b of the upper surface plate 3a are arranged so as to be surrounded by the wire rod coil 2, and the covering plate 9 is placed on the wire rod coil 2.

As a result, the protrusion 10 is inserted into the hollow portion 2b inside the wire rod coil 2, the cushion material 11 abuts on the upper end 2c which is one side of the wire rod coil 2, and the entire area on the wire rod coil 2 is covered by the covering member 5. ..

That is, the covering member 5 abuts on the upper end 2c of the wire rod coil 2 in the penetrating direction to cover the wire rod coil 2.

When cooling a plurality of wire rod coils 2, the positions of the wire rod coils 2 are aligned and the cavities 2b are stacked so as to be continuous.

When the wire coil 2 is stacked on the mounting table 3, the wire coil 2 is placed on the mounting table 3 in a state where the hanging top plate 7 is lifted higher than the mounting table 3 position together with the covering plate 9 via the rod 8. I will put it on. The stacking height (stacked number) of the wire rod coils 2 is different each time. After the mounting of the wire coil 2 on the mounting table 3 is completed, the hanging top plate 7 is lowered. After the cover plate 9 rides on the upper end 2c of the wire rod coil 2, the hanging top plate 7 is further lowered while the rod 8 slides with respect to the cover plate 9, and is suspended at the set minimum lowering position each time. The top plate 7 is stopped.

With the wire rod coil 2 mounted on the mounting table 3 and the covering member 5 mounted on the wire rod coil 2, air is blown from the blower hole 3b toward the covering plate 9 side.

At this time, the weight of the covering member 5 is set so that the covering member 5 does not rise due to the wind pressure.

The air blown from the blower hole 3b toward the cover plate 9 side flows through the cavity 2b toward the protrusion 10 of the cover member 5.

As shown in FIG. 4, the air between the blower hole 3b and the protrusion 10 spreads in the wire coil 2 in the outer peripheral direction (from the inside to the outside of the wire coil 2), and the wire coil 2 and the protrusion 10 The air that has entered the gap S between the spaces also enters the gap S, and the air that has entered the gap S further spreads in the wire rod coil 2 in the outer peripheral direction (from the inside to the outside of the wire rod coil 2) while facing the cover plate 9 side.

Therefore, in the case of FIG. 5 in which the protrusion 10 is not provided, the dynamic pressure of air becomes extremely high only around the cover plate 9 in the cavity 2b. Due to the effect of the void S, air easily escapes from the periphery of the covering plate 9, so that a substantially uniform dynamic pressure is generated in the entire cavity 2b from the lower end 2d to the upper end 2c of the wire rod coil 2.

That is, according to the cooling device 1 of the present embodiment, when the upper end 2c of the wire coil 2 and a plurality of wire coils 2 are stacked, the wire coil 2 comes into contact with the upper end 2c of the uppermost wire coil 2. In order to equalize the dynamic pressure in the cavity 2b by being inserted into the cavity 2b inside the wire rod coil 2 into the covering member 5 so that the dynamic pressure due to the ventilation is lowered on the covering member 5 side. Since the protrusion 10 is provided, the portion having high dynamic pressure does not concentrate only on the covering member 5 side, and the amount of air passing between the wire rods 2a of the wire rod coil 2 is made uniform in the entire wire rod coil 2. Can be. Thereby, the wire rod coil 2 can be cooled more uniformly.

Since the covering member 5 is guided by the rod 8 suspended from the hanging top plate 7 suspended from above and moves in the vertical direction, for example, the number of stacked wire coil 2 is different, so that the covering member 5 is Even if the closing position (height) is changed, the wire 6 that suspends the suspension support 4 does not loosen.

That is, when the wire 6 is arranged by the pulley 12, when the hanging top plate 7 is directly suspended by the wire 6 as shown in FIG. 6, the hanging top plate 7 is mounted on the wire rod coil 2. Later, the wire 6 may loosen and inadvertently come off the pulley 12.

In the present embodiment, since the cover plate 9 slides with respect to the rod 8 of the hanging top plate 7, the length of the wire 6 is determined so as to be in a stretched state at the highest position of the expected wire coil 2. You should keep it. As a result, the hanging top plate 7 can be lowered, and even after the cover plate 9 rides on the upper end 2c of the wire coil 2, the hanging top plate 7 can continue to be lowered, and what is the stacking height of the wire coil 2. Even in such a case, since the wire 6 is stopped in a stretched state, the wire 6 does not come off from the pulley 12, and troubles in the hanging operation can be eliminated.

Since the covering member 5 is guided by a plurality of rods 8 suspended from the hanging top plate 7, it is possible to prevent the cover member 5 from being displaced with respect to the wire rod coil 2.

That is, the covering member 5 does not shift in position with respect to the wire rod coil 2 even while the hanging top plate 7 is descending while sliding with respect to the rod 8.

Since the cover member 5 is provided with the cushion material 11 at a portion facing the wire rod coil 2, it is possible to reliably prevent the wire rod coil 2 from being damaged by the cover member 5.

FIG. 7 shows a modified example of the above embodiment. The surface of the upper end 2c of the wire rod coil 2 is not necessarily horizontally flat, but may be inclined. In this modification, even when the surface of the upper end 2c of the wire coil 2 is inclined in this way, the cover plate 9 can be installed in an inclined state on the surface, and the upper end 2c of the wire coil 2 is preferable. It is made to be able to be closed.

First, the hole diameter of the insertion hole 9b of the covering plate 9 is formed to be larger than the outer diameter of the rod 8. As a result, the cover plate 9 is allowed to be tilted with respect to the rod 8, and the cover plate 9 can be installed on the upper end 2c of the wire rod coil 2 in accordance with the inclination of the surface of the upper end 2c.

Further, the upper surface of the stopper 8a of the rod 8 is formed in a cone shape that narrows upward, and the insertion hole 9b itself is formed in a cone shape that expands downward, or the same applies to the lower part of the insertion hole 9b. It is preferable to attach a cone-shaped guide member 14.

By doing so, when the hanging support 4 rises, the stopper 8a enters the insertion hole 9b or the guide member 14, and the covering plate 9 can be returned to the horizontal posture and centered and lifted.

Even in such a modified example, the same effect as that of the above embodiment can be obtained, and as described above, even if the surface of the upper end 2c of the wire rod coil 2 is inclined, the covering plate 9 can be used. It can be properly installed to efficiently cool the wire coil 2.

The above embodiment is for facilitating the understanding of the present invention, and is not for limiting the interpretation of the present invention. It goes without saying that the present invention can be modified and improved without departing from the spirit thereof, and the present invention includes an equivalent thereof.
