Abstract

(57) [Summary] [Object] The present invention has a simple structure for dropping a hot-molded and conveyed bar material to a cooling conveyance floor by a trough, and easy operation for adjusting the trough height position. It is intended to provide a new device. [Arrangement] The arm 11 to which the troughs 51 and 52 are attached is attached to a shaft 62. The shaft 62 is rotationally driven by the air cylinder 15 via the drive arm 14, whereby the arm 11 is rotated around the shaft 62. When the troughs 51, 52 that have received the rod 50 are moved downward, the rod 50 is placed on the slide plate 58 and dropped to the cooling transport floor below. The height positions of the troughs 51 and 52 can be adjusted by wedge-type height position adjusting means having the wedge 1 attached to the arm 11. Further, the lowermost slide plate 8 which engages with the cooling and transporting floor rotates around the hinge 9 by its own weight and always keeps engaging with the cooling bed 81.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for dropping a bar material, which is hot-formed and conveyed in the length direction, by a trough to a lower cooling conveyance floor.

[0002]

2. Description of the Related Art A conventional run-in trough type rod dropping and conveying apparatus will be described with reference to FIG. In the figure, 53 is an arm, which is rotatably pivotally attached to a beam 55 installed between brackets 59 of a plurality of stands 54, and has a trough 51 and a trough 51 divided in the length direction at one end thereof. The troughs 52 for large diameter steel bars are mounted respectively.

Reference numerals 56 and 57 are lid plates, and the troughs 51 and 5
Each of the beams 55 is fixed to cover the upper surface of the beam 2. Reference numeral 58 is a sliding plate, and each trough 51, 5
It is interposed between the two divided portions and is fixed to the bracket 59. Reference numeral 61 denotes an arm, which is fitted on a shaft 62 supported by a stand 54 by a bearing block 63, and its tip end is connected to the other end of the arm 53 by a turnbuckle 60.

A drive arm 64 is fitted on the shaft 62, and an air cylinder 65 is attached to its tip. 71 is a guide, via the bracket 72,
It is fixed to the stand 54.

Reference numeral 81 is a cooling bed, which is a steel bar 50.
It is divided and fixed in the length direction. Reference numeral 82 is a walking beam whose surface shape is the same as that of the cooling bed 81, and the bar steel 50 is fed one pitch at a time in the arrow direction by repeating ascending, advancing, descending and retracting.

Each turnbuckle 60 is expanded and contracted to change the angle of the arm 53 so that each trough 51, 52 is optimal for receiving the steel bar 50 from a lengthwise conveying device (not shown) and is divided into each. The heights of the troughs 51 and 52 are adjusted so that the troughs 51 and 52 have the same height and form appropriate gaps with the lid plates 56 and 57.

Next, the hot-formed steel bar 50 is received from the transfer device to the trough 51, the driving arm 64 and the arm 61 are rotated around the shaft 62 by the air cylinder 65, and further, via the turnbuckle 60. The arm 53 is rotated to rotate the troughs 51 and 52 downward. The sliding plate 58 receives only the steel bar 50 that rotates downward together with the trough 51, and guides the bar steel 50 to a certain falling position by the guide 71, and drops it onto the cooling bed 81 and the walking beam 82.

The cooling bed 81 and the walking beam 82 are successively cooled while cooling the high temperature steel bar 50.
Transfer to the next process. When the steel bar 50 is dropped, the troughs 51, 52 are rotated upward by the air cylinder 65 to return to the original position, and the steel bar 50 to be conveyed next is received. When the large diameter steel bar 50 is fed to the lower two troughs 52, it is dropped onto the cooling bed 81 and the walking beam 82 by the same action as described above.

[0009]

The conventional device described above has the following drawbacks.

(1). The structure of the device for rotating the troughs 51, 52 in the vertical direction is complicated, and the manufacturing cost and maintenance cost of the device increase.

(2). Since an expensive turnbuckle 60 is used as the height position adjusting means for each of the troughs 51, 52, the manufacturing cost of the device increases and the height position adjusting operation is difficult.

(3). Stand 54, bracket 59,
Since the sliding plate 58, the cooling bed 81 and the like are steel welded structures, the dimensional accuracy thereof is reduced due to deformation during use, bending due to the weight of the steel bar 50, etc.
8, cooling head 81 and walking beam 82
There is a possibility that the and will come into contact with each other and press to cause a problem in the operation of the walking beam 82, or the gap between them will expand, and the steel bar 50 will fall behind the cooling bed 81.

(4). Since the bearing of the trough 52 is easily affected by the secondary heat of the steel bar, it is necessary to take measures such as a heat insulating plate.

It is an object of the present invention to provide a device which does not have these drawbacks found in the conventional device, has a simple structure, and is easy to adjust the height position of the trough.
It is another object of the present invention to provide a device in which a bar does not drop behind the cooling head due to a gap between the upper surface of the cooling transfer floor and the lowermost slide plate. I am trying.

A sliding member provided so as to abut against the upper surface of the cooling transfer floor to set its height and to move up and down by its own weight according to the height change of the upper surface of the cooling transfer floor is also adopted.

[0017]

According to the present invention, since the trough height position adjusting means such as a wedge type for adjusting the height of the trough from the arm supporting the trough is adopted, the trough position is adjusted by this adjusting means. Is optimal and the heights of the divided troughs are adjusted to be the same.

The trough receives the hot-molded high-temperature rod member from the lengthwise conveying device, the drive shaft is rotated, and the arm and trough are rotated downward together with the rod member. The sliding member receives only the bar that rotates downward, and drops it onto the cooling transfer floor. The cooling / conveying floor conveys the rod material to the next step while cooling it.

Further, in the apparatus of the present invention which employs a sliding member which can be moved up and down by its own weight according to the height change of the upper surface of the cooling transfer floor in the above-mentioned apparatus, the sliding member and the cooling transfer floor are not properly engaged. The sliding member is satisfactorily engaged by the automatic height adjusting method of the sliding member.
