Description

Coil car with variable coil support point {A COIL CAR FOR VARYING COIL FIXING POSITIONS}

The present invention relates to a coil car for carrying a coil wound as a mandrel to facilitate movement and storage of a strip (STRIP) produced by rolling a slab in an iron mill, and more particularly, to a coil car. By varying the coil support point of the cradle roll of the coil car according to the diameter of the seated coil, it prevents the failure of the coil, such as the distortion of the coil when the coil car is seated, and smoothly removes the coil from the mandrel. The present invention relates to a coil car having a variable coil support point.

1 illustrates a mandrel and a coil car for winding a strip that has been subjected to a general rolling process to a coil and moving the strip.

That is, as shown in FIG. 1, the strip 120 conveyed as the pinch roll 110 is wound from the mendrel 130 to the coil C, and the coil C wound to a constant diameter is disposed below. Seated on the coil car 200 is moved to the coil loading line.

On the other hand, Figure 2 shows a conventional coil car 200 as described above, about four cradle rolls 220 for rotatably supporting the coil on the upper side of the coil car body 210 is rotatably installed The coil car body 210 is mounted on a coil car body (not shown) and moved up and down by a cylinder disposed therein so that the coil C wound on the mandrel 130 is seated and supported.

By the way, the diameter of the coil (C) to be manufactured is varied according to the demand of the consumer or the size of the facility of the line for moving and loading, as shown in Figure 3a, on the body 210 of the coil car 200 In the state where the interval between the left and right cradle rolls 220 provided in the state can stably support the coil C, that is, the diameter of the coil is appropriate, the coil is stably seated and supported on the conventional coil car 200.

However, as shown in FIGS. 3A and 3B, the conventional coil car 200 and the gradle roll 220 are fixedly mounted on the coil car body 210, and as shown in FIG. 3B, the men If the diameter of the coil C wound as the drill 130 is too large, the cradle roll support points P1 and P2 of the coil C supported by the cradle rolls 220 are too narrow to seat the coil car of the coil C. Since the state is unstable, especially in the case of a coil made of a material of high carbon steel, for example, S45C, S50C, S55C, etc., the inside of the coil C becomes a collapsing collapsing coil in the wound state in the mendrel 130. A portion of the winding is too close to the mandrel 130 to make it very difficult to separate the coil (C) from the mandrel.

As a result, there is a problem in that it is difficult to produce a smooth coil product because the winding operation of the new coil is delayed as well as the removal of the mandrel of the wound coil.

Therefore, if the cradle roll of the coil car supporting the coil is varied according to the diameter of the coil, the support points of the coil (P1 and P2 in FIG. 3B) may be varied, which is more preferable.

The present invention has been made to improve the various problems as described above, the object of the present invention is to provide a variable position of the gradle roll of the coil car in close contact with the coil according to the diameter of the coil wound in the mandrel, The coil is more stably seated and supported by the coil car, as well as providing a coil car having a variable coil support point that further improves the product productivity of the coil by smoothly separating the coil from the mandrel as the coil is crushed.

Next, FIG. 4 and FIG. 10 show the cradle roll support part 80 of the coil car 1 of the present invention. The cradle roll support part 80 is a vertical stand extending to both sides of the upper end of the body 10. A plurality of support rolls 84 are provided to be inclined to move inwardly of the 82 to elastically support the side of the frame 66 of the coil support 60.

That is, as shown in Figure 10, the support roll 84 of the cradle roll support portion 80 is inserted into the casing 86 fixed inclined to the outside of the vertical stand 82 of the upper end of the body (10) Passing through the vertical stand 82 and the outer side is made of a configuration that is installed in two rows on the fixed plate 92 fixed to the upper end of the operating rod 90, the second spring 88 is installed.

Referring to the operation of the present invention made in the above configuration in detail as follows.

As shown in Figures 4 to 11, the coil support point of the present invention to more stably support the coil (C) by varying the cradle roll (68) for supporting it according to the diameter of the coil to vary the coil car (1) is as follows.

First, as shown in FIG. 5, before the coil C wound around the initial mendrel m is seated on the cradle roll 68 of the coil car 1, the cradle rolls 68a and 68b. The support rolls 84 in close contact with the side of the frame 66 are in a state in which the support rolls 84 are narrowed toward the roll roll plate 44 at the center by the elastic force of the second springs 88 of the roll support 80.

Next, as shown in FIGS. 6 and 8, when the coil C moves downward with the mandrel m, the watch plate 44 disposed below the central axis of the coil C is first placed on the coil. As the first spring 48 is pressed while being pressed, and the support bar 49 to which the quench plate 44 is connected is lowered, the first shaft 42 inserted into the connection ring 46 at the lower end thereof has both ends thereof. Needle bearing (B) is lowered along the central end (20a) of the guide means 20 shown in FIG.

At this time, the connecting block 64 connected to the first shaft 42 is connected to the second shaft 62 at the same time so that the first shaft 42 is stable without left and right flow along the center end 20a of the guide means. As it is lowered, and as shown in Figure 5 when the pressing operation of the coil (C) disappears is to rise to the elastic force of the first spring 48 to return to the initial position.

Next, as shown in FIG. 6, when the coil C is lowered to press the cradle rolls 68a and 68b of the roll variable support 60, the frame 66 on which the cradle rolls 68 are mounted is shown in FIG. 6. Linked to the second shaft 62 in which the needle bearing B of the end is inserted into both side ends 20b and 20c of the guide means 20 shown in FIG. 9, the frame 66 is a coil car body. It is pushed to both sides of the vertical stand 82 side of the (10).

Therefore, as shown in FIGS. 6 and 10, when the frame 66 moves to the left and right sides, the fixing plate 92 provided with the support rolls 82 of the roll support units 80 in close contact with both sides of the frame 66 is installed. The second spring 88, which is fixed to the rear end and inserted into the casing 86 installed inclined outwardly of the vertical stand 82, is pushed backward while the second spring 88 is installed therein is compressed. Cradle roll 68 on 66 is to stably support the lower circumferential surface of the coil (C).

At this time, the important thing is to have the elastic force of the second spring 88, that is, the elastic force enough to support the coil (C) in the maximum compressed state, as shown in Figure 11a and 11b, When the diameter of the coil C is variable, the weight of the coil is variable, and thus the load force for pressing the cradle rolls 68 is different, so that the elastic force of the second spring 88 corresponds to the cradle roll 68 accordingly. ) To support the installed frame (66).

Accordingly, as shown in FIG. 11, cradle rolls 68 according to the present invention have a supporting point, that is, a support point of the coil C, according to the diameter of the coil, as shown in FIG. 11. Since the intervals d1 and d2 are variable, the coils can be more stably supported, and ultimately, the coils of the mandrel m due to the duckbill coil C shown in FIG. It is.

As described above, according to the coil car having the variable coil support point of the present invention, the coil is more stable to the coil car by installing the gradle roll of the coil car that closely adheres to the coil and supports the coil according to the diameter of the coil wound in the mandrel. As well as being seated and supported, the separation operation in the mandrel as the coil is crushed is smooth, and thus the coil is easily moved, thereby providing an excellent effect of improving the productivity of the coil product.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to know that those who have knowledge of this can easily know.
