Abstract
The utility model discloses a position-adjusting mechanism for a cooling water pipe of a bottom roll, wherein a cooling water pipe comprises an arc-shaped spray pipe and a water inlet straight pipe fixedly connected to the outer side surface of the arc-shaped spray pipe; the water inlet straight pipe is fixedly inserted into a through hole formed on a fixing seat; a plurality of waist-shaped through holes are formed on the fixing seat; and a bolt which is used for fastening the fixing seat on a fixing frame is arranged in each waist-shaped through hole. By adjusting the fixing position of the bolt in the waist-shaped through holes, the position of the fixing seat can be adjusted, so that the distance between the arc-shaped spray pipe and the bottom roll can be adjusted. The position-adjusting mechanism for a cooling water pipe of a bottom roll is particularly suitable for section bar rolling production lines of a steel rolling mill, and has the following advantages: the position-adjusting mechanism for a cooling water pipe of a bottom roll can adjust the distance between the arc-shaped spray pipe and the bottom roll, which has a simple structure and is convenient to adjust and operate, so as to improve the security and work efficiency of the steel rolling production work and the like.
Description
Technical field
The utility model relates to a kind of position adjusting mechanism, especially a kind of position adjusting mechanism that is used for the bottom roll cooling water pipe of steel rolling mill's section rolling production line.
Background technology
In the Rolling Production process of section bar, when the high temperature rolled piece passes through milling train, the high temperature rolled piece is rolled by roll.Because roll constantly contacts with the high temperature rolled piece, thereby the temperature of roll can constantly raise.Too high temperature can reduce the intensity and the toughness of roll, and makes roll wear accelerate, and shorten service life, thereby usually need to set the water cooling plant that is used to reduce roller temperature on the milling train.
On the milling train of present section rolling, milling train topping roll and bottom roll are not generally established special cooling device.Some steel mills are provided with cooling water pipe near roll, but cooling water pipe normally is fixedly welded on the support, can not move.In the actual use of milling train, roller diameter also can be with repeatedly diminishing gradually after the processing behind the roll wear, make the distance between roller surface and the water cooling plant increase gradually, cooling effect also can variation, thereby roller temperature raises, degradation, has accelerated the wearing and tearing of roll, has shortened the service life of roll, can cause production accident when situation is serious, reduce the security of producing.Owing to need often to change roll, strengthened working strength of workers, increased production time, reduced operating efficiency.
The utility model content
The utility model is the weak point that exists in the above-mentioned prior art for avoiding, and a kind of position adjusting mechanism of bottom roll cooling water pipe is provided, so that the distance between arc sparge pipe and the bottom roll guarantees favorable cooling effect.
The utility model be the technical solution problem by the following technical solutions.
The position adjusting mechanism of bottom roll cooling water pipe, its design feature is, cooling water pipe comprises that the inboard is provided with the arc sparge pipe of hole for water spraying and is fixedly connected on water inlet straight tube on the lateral surface of described arc sparge pipe, the water inlet straight tube fixedly is plugged in the through hole on the holder, holder is provided with a plurality of waist through hole, is provided for holder is anchored on bolt on the fixed mount in waist through hole.
The design feature of the position adjusting mechanism of bottom roll cooling water pipe of the present utility model also is:
Described holder is provided with 4 waist through hole.
Between described holder and described fixed mount, be provided with rubber sheet gasket.
Be arranged with spring washer and plain washer on the described bolt.
Described water inlet straight tube is fixedly welded in the through hole on the holder.
Compared with the prior art, the utility model beneficial effect is embodied in:
Position adjusting mechanism of the present utility model, after roller diameter diminished instantly, the water that sprays in the arc sparge pipe just can't be sprayed onto on the bottom roll fully, causes the cooling effect variation; After bolt unscrewed, mobile holder was adjusted distance between arc sparge pipe and the bottom roll by adjusting the position of bolt in waist through hole, and then bolt is tightened the adjustment that can finish the distance between arc sparge pipe and the bottom roll.Position adjusting mechanism of the present utility model can be realized the adjustment of the distance between arc sparge pipe and the bottom roll, and is simple in structure, adjust convenient to operation, thereby guaranteed cooling effect, avoided the harmful effect that causes because of the water-cooled deleterious, improved the security and the operating efficiency of producing.
The utility model is particularly useful in the section rolling production line of steel rolling mill.
Description of drawings
Fig. 1 is the front view of the position adjusting mechanism of bottom roll cooling water pipe of the present utility model.
Fig. 2 is the left view of the position adjusting mechanism of bottom roll cooling water pipe of the present utility model.
Label in accompanying drawing 1, the accompanying drawing 2: 1 arc sparge pipe, 2 bolts, 3 spring washers, 4 plain washers, 5 holders, 51 waist through hole, 6 rubber sheet gaskets, 7 fixed mounts, 8 water inlet straight tubes.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment
Referring to Fig. 1, Fig. 2, the position adjusting mechanism of bottom roll cooling water pipe, cooling water pipe comprises that the inboard is provided with the arc sparge pipe 1 of hole for water spraying and is fixedly connected on water inlet straight tube 8 on the lateral surface of described arc sparge pipe 1, water inlet straight tube 8 fixedly is plugged in the through hole on the holder 5, holder 5 is provided with a plurality of waist through hole 51, is provided for holder 5 is anchored on bolt 2 on the fixed mount 7 in waist through hole 51.In the working site, usually with guide and guard beam balladeur train as fixed mount 7, holder 5 is fixed on the balladeur train.Described holder 5 is provided with 4 waist through hole 51.Between described holder 5 and described fixed mount 7, be provided with rubber sheet gasket 6.Be arranged with spring washer 3 and plain washer 4 on the described bolt 2.Spring washer 3 and plain washer 4 are located between bolt head and the holder 5, to improve the tightness of bolt 2.Described water inlet straight tube 8 is fixedly welded in the through hole on the holder 5.
Position adjusting mechanism of the present utility model is fixedly welded on cooling water pipe on the holder, and holder is provided with a plurality of waist through hole, by the bolt in the waist through hole holder is connected on the fixed mount.Because waist through hole has certain distance on its length direction, so can adjust the position of bolt in waist through hole.By adjusting the position of bolt in waist through hole, realize adjusting the purpose of the distance between arc sparge pipe and the bottom roll.
Position adjusting mechanism of the present utility model, after roller diameter diminished instantly, the water that sprays in the arc sparge pipe just can't be sprayed onto on the bottom roll fully, causes the cooling effect variation; After bolt unscrewed, mobile holder was adjusted distance between arc sparge pipe and the bottom roll by adjusting the position of bolt in waist through hole, and then bolt is tightened the adjustment that can finish the distance between arc sparge pipe and the bottom roll.Position adjusting mechanism of the present utility model can be realized the adjustment of the distance between arc sparge pipe and the bottom roll, and is simple in structure, adjust convenient to operation, thereby guaranteed cooling effect, avoided the harmful effect that causes because of the water-cooled deleterious, improved the security and the operating efficiency of producing.
The utility model is particularly useful in the section rolling production line of steel rolling mill.
