Abstract
The invention discloses a position adjusting mechanism of a bottom roll cooling water pipe. The cooling water pipe comprises an arc water spraying pipe and a water inlet straight pipe fixedly connected to the outer side face of the arc water spraying pipe. The water inlet straight pipe is fixedly inserted in a through hole in a fixing base in a connected manner. A plurality of kidney-shaped through holes are formed in the fixing base. Bolts for fixing the fixing base to a fixing frame are arranged in the kidney-shaped through holes. The position of the fixing base can be adjusted by adjusting the fixing positions of the bolts in the kidney-shaped through holes, and then the distance between the arc water spraying pipe and a bottom roll can be adjusted. The position adjusting mechanism is particularly suitable for a sectional bar rolling production line of a rolling mill, and the position adjusting mechanism has the beneficial effects that the distance between the arc water spraying pipe and the bottom roll can be adjusted, the structure is simple, the adjustment operation is convenient and fast, and the safety and work efficiency of the steel rolling production work can be improved.
Description
Technical field
The present invention designs a kind of position adjusting mechanism, particularly relates to a kind of position adjusting mechanism for rolling mixed cooling water pipe under steel rolling mill's section rolling production line.
Background technology
In the Rolling Production process of section bar, when high temperature rolled piece is by milling train, be rolled because roll constantly contacts with high temperature rolled piece by roll to high temperature rolled piece, thus the temperature of roll can constantly raise.Too high temperature can reduce intensity and the toughness of roll, and roll wear is accelerated, and service life shortens, and thus milling train usually needs to arrange the water cooling plant for reducing roller temperature.On the milling train of current section rolling, milling train topping roll and general of bottom roll are not provided with special cooling device.Some steel mills arrange cooling water pipe near taking root, but cooling water pipe is normally fixedly welded on support, can not move.In the actual use procedure of milling train, roller diameter also can diminish gradually after repeatedly processing after roll wear, distance between the roller surface being and water-cooling apparatus increases gradually, cooling effect also can be deteriorated, thus roller temperature raises, degradation, accelerates the wearing and tearing of roll, shortens the service life of roll, can production accident be caused when situation is serious, reduce the security of production.Because needs often change roll, increase the labour intensity of workman, add the Operational preparation time, reduce operating efficiency.
Summary of the invention
The present invention is the weak point existed in above-mentioned prior art, provides a kind of position adjusting mechanism of bottom roll cooling water pipe, so that the distance of arc sparge pipe between bottom roll, ensures good cooling effect.
The present invention be technical solution problem by the following technical solutions.Whom bottom roll cools and dares guiding mechanism, its design feature is, cooling water pipe comprises the arc sparge pipe that inner side is provided with hole for water spraying and the water inlet straight tube be fixedly connected on the lateral surface of described arc sparge pipe, water inlet straight tube is fixedly plugged in the through hole on holder, holder was provided with a waist through hole, arranged for shareholder's seat being anchored on the bolt on fixed mount in kidney-shaped pupil.Mechanical feature of the present invention is, described holder is provided with 4 waist through hole.Rubber sheet gasket is provided with between described holder and described fixed mount.Described bolt is arranged with spring washer and plain washer.Described water inlet straight tube welding is fixed in the through hole on holder.
The invention has the beneficial effects as follows: position adjusting mechanism of the present invention, after roller diameter diminishes instantly, the water sprayed in arc sparge pipe just cannot be sprayed onto on bottom roll completely, causes cooling effect to be deteriorated; After part bolt is unscrewed, mobile holder, adjusts distance between arc sparge pipe and bottom roll by the adjustment position of bolt in waist through hole, and then by the adjustment of bolt tightening and the distance between flexure arc sparge pipe and bottom roll.Position adjusting mechanism of the present invention, can realize the adjustment of the distance between arc sparge pipe and bottom roll, structure is simple, adjust convenient to operation, thus ensure that cooling effect, avoid the harmful effect caused because of water cooling deleterious, improve security and the operating efficiency of production.The present invention is particularly useful in the section rolling production line of steel rolling mill.

Detailed description of the invention
See Fig. 1--Fig. 2, the position adjusting mechanism of bottom roll cooling water pipe, cooling water pipe comprises the arc sparge pipe 1 that inner side is provided with hole for water spraying and the water inlet straight tube 8 be fixedly connected on the lateral surface of described arc sparge pipe 1, water inlet straight tube 8 is fixedly plugged in the through hole on holder 5, holder 5 is provided with multiple waist through hole 51, the bolt 2 being used for being anchored on by holder 5 on fixed mount 7 is set in waist through hole 51, in working site, usually using guide beam balladeur train as fixed mount 7, holder 5 is fixed on balladeur train, described holder 5 is provided with 4 waist through hole 51, rubber sheet gasket 6 is provided with between described holder 5 and described fixed mount 7, on described bolt 2, great waves have taken the photograph spring washer 3 and plain washer 4. spring washer 3 and plain washer 4 sandwiched and between bolt head and holder 5, to improve the tightness of bolt 2.Described water inlet straight tube 8 is fixedly welded in the through hole on holder 5.
Position adjusting mechanism of the present invention, is fixedly welded on cooling water pipe on holder, and holder is provided with multiple waist through hole, is connected on fixed mount by holder by the bolt of waist through hole.Because waist through hole has certain distance in their length direction, so the position of bolt can be adjusted in waist through hole.By the adjustment position of bolt in waist through hole, realize the object of the distance between adjustment arc sparge pipe and bottom roll.Position adjusting mechanism of the present invention, after roller diameter diminishes instantly, the water of arc sparge pipe ejection just cannot be sprayed onto on bottom roll, causes cooling effect to be deteriorated; After being unscrewed by bolt, mobile holder, adjusts the distance between arc sparge pipe and bottom roll by the adjustment position of bolt in waist through hole, and then bolt tightening can be completed the adjustment of the distance between arc sparge pipe and bottom roll.Position adjusting mechanism of the present invention, can the adjustment of distance between real arc sparge pipe and bottom roll, and structure is simple, adjust convenient to operation, thus ensure that cooling effect, avoid the harmful effect caused because of water cooling deleterious, improve security and the operating efficiency of production.
