The present invention relates to a cooling water sprinkling apparatus, and more particularly, to a wire rough rolling roll cooling water sprinkling apparatus for cooling a roll as a rough rolling facility of wire rolling which is hot rolling.

With reference to FIG. 1 and FIG. 2, the cooling water sprinkling apparatus in the conventional wire rod rolling process is demonstrated.

Wire roll roughening consisting of a coolant water jaket (3) having two rolls (1) on which a plurality of calibers (2) are formed, and a plurality of nozzles (20) installed on the side of the roll (1). The roll of the city is cooled.

Reference numeral 4 is a fixing bolt for fixing the fixing bar (5), 6 is a stand housing, 7 is an exit guide, 8 is an exit guide box, 9 is a guide box holder, 10 is a guide box holder fixing bolt, 11 is an exit guide The box moving bolt, 17, is a coolant inlet main valve.

In the wire rod rolling process provided with the cooling device having the above-described configuration, the roll 1 and the caliber 2 are replaced more frequently than the other rolls in view of the processing conditions of the roll 1, and the caliber 2 per roll 1 is used. ) Is small and 4 to 14 are processed in one roll 1, and are used.

The cooling is inconvenient to manually move the coolant sprinkling pipe 3 for each caliber 2 under the purpose of cooling water to the caliber 2 used.

In addition, as a structural problem according to the structure itself, since the caliber 2 is mainly fixed using the M16 × 70 fixing bolt 4, it is difficult to disassemble and replace during the replacement work due to corrosion by the cooling water and the cooling water spray pipe 3 The center of the caliber (2) does not fit correctly, so that the coolant water pipe (3) is dropped due to the roll (1) heat generation and rolling vibration shock, causing the roll (1) to be broken and a lot of personnel are put in, and the trouble time is too long. Is that.

For reference, as a result of measuring the time required to move the coolant sprinkling pipe (3), when the M16 × 70 fixing bolts (4) were dismantled, the unscrewing time of the four driving and four working sides was 8 minutes. It took 12 minutes to move the sprinkler to the next caliber at. The screw tightening time of the four driving and four working sides was 7 minutes when the M16 × 70 fixing bolts 4 were assembled.

Therefore, there is a problem in that a total of 27 minutes spent two people in a pair of people to move the cooling water spray pipe (3).

In addition, since the conventional cooling water spray pipe 3 is too far from the roll 1 and the spray angle is set to 90 ° with respect to the roll 1, the cooling water is scattered so that it is impossible to check the equipment by the cooling water. Since the nozzle shape is not a nozzle but a round shape, the coolant is sprinkled in a straight line, so that the coolant cannot be sprayed on the entire caliber 2 so that the roll 1 and the caliber 2 which are rolling cannot be reached. It is sprinkled, and the rolling heat is conducted to the caliber 2 part, and it always has high heat, and the cooling effect of the roll 1 falls, and it is pointed out that it is a big problem to reduce the unit of roll 1 due to premature wear and breakage of the roll. .

In addition, the coolant water sprinkling pipe 3 and the nozzle 20 are designed in a straight 90 ° direction, for example, the minimum usable waste due to the wear processing at a roll dia 600 mm in diameter. Since the use of the roll diameter up to 525mm, the spraying distance is too far, the cooling effect of the roll (1) is more severe when the waste rolls are used, and the heat of rolling is conducted to the caliber (2) so that it always has high heat.

The present invention is to solve this problem in view of the above, the purpose is to use a water spray pipe having a nozzle of a special shape and the cooling water spray pipe during the caliber replacement operation by using a clamp to fix or move the water pipe It provides a wire rod rough rolling roll cooling water sprinkling device which moves smoothly, and the movement is also fully automated, which greatly reduces the time required to move the sprinkler.

Wire rod rough rolling roll cooling water sprinkling apparatus of the present invention for achieving the above object comprises a cooling water sprinkling pipe having a plurality of injection nozzles for cooling the rolling roll formed caliber, and a clamp base for fixing the cooling water sprinkling pipe In the wire rough rolling roll cooling water sprinkling device of the above configuration, the clamp base is provided on both sides of the outlet guide box by predetermined fastening means, and the two sets of clamps each having a V-shaped groove are attached thereto. The upper and lower ends of the clamp are coupled to each other by a fixing nut, a fixing bar, and a predetermined number of flow pins, which are fixed to the clamp fixing bolt by the clamping bolt, and the spray nozzles installed on the spray pipes have an installation angle with respect to the center of the roll. Is set to 25 °, while at least two of these jetting nozzles are positioned to face the center of the roll. Has been arranged in the zag form, the spray tube is in the shape forming the oval, which accounts for 1/4 to the outside of the roll.

Therefore, the wire rod rough rolling roll cooling water sprinkling device of the above structure makes the cooling water jet nozzle in a half-moon shape to increase the water spray width to increase the cooling effect, and the improved water pipe is close to the roll as much as possible in the roll of the new roll diameter. Coolant can be sprayed accurately to the roll diameter of the closed roll, and the installation angle of the coolant spray nozzle is adjusted from 90 ° to 25 ° to increase the spraying pressure due to the roll rotation direction and the spraying direction. have.
