Abstract
The utility model discloses a hot rolling coiler mandrel, comprising a coiler mandrel shaft and a spiral water-feeding device arranged at the tail end of the coiler mandrel shaft. The spiral water-supply device is provided with a fixing sleeve, and a bearing is respectively arranged at two inner ends of the fixing sleeve and an annular water-feeding tank is arranged in the middle of the fixing sleeve. Two seal rings are respectively arranged on two sides of a water tank, and an annular draining groove is respectively arranged between two seal rings. A water intake used for feeding water for the annular water-feeding tank and a water outlet used for draining water from the annular draining groove are arranged on the fixing sleeve. The fixing sleeve is arranged on the shaft of the coiler mandrel through bearings. A cooling water hole is cut on the coiler mandrel shaft corresponding to the annular water tank, and the cooling water hole is extended all along to an expansion end at the front part of the coiler mandrel shaft. The hot rolling coiler mandrel can lead the cooling water to go from the tail of the coiler mandrel shaft to the expansion end at the front part of the coiler mandrel shaft for constantly cooling the inner parts of sector plates and the coiler mandrel shaft, with a very positive significance for enhancing the quality and manufacturing efficiency of products, and the service life of the coiler mandrel can be dramatically prolonged.
Description
Technical field
The utility model relates to a kind of hot rolling coiler reel that is used for hot-strip.
Background technology
The hot rolling coiler reel that present China generally uses is a kind of coiler mandrel that does not have internal water cooling, the type reel is after unloading volume, spray cooling by the nozzle on the outside frame of reel, because the temperature of the hot-strip that reel batches is up to 600-800 ℃, therefore the effect of the temperature of fanning strip, spool shaft and the inner body thereof of this coiler mandrel reduction is not satisfactory, directly has influence on the service life and the production efficiency of reel thus.
The utility model content
The purpose of this utility model is to provide a kind of large-scale rotation feed feeder of being with, the hot rolling coiler reel that by the reel private water supply fanning strip, spool shaft and inner body thereof is cooled off when batching hot-strip.
This hot rolling coiler reel that the utility model provides comprises spool shaft, also comprise the rotation feed feeder that is installed in described spool shaft rear, this rotation feed feeder has fixed cover, fixed cover is provided with the inlet opening, two ends are bearings in fixed cover, the centre is annular supply flume, the both sides of tank respectively are provided with the two seals circle, one annular sluicing groove is respectively arranged between the two seals groove, fixed cover is provided with the inlet opening of sending water for annular supply flume, osculum for the draining of annular sluicing groove, fixed cover is installed on the spool shaft by bearing, spool shaft has a cooling water hole in corresponding position with described annular water tank, and this cooling water hole one is through to the breathing end of spool shaft front portion.
The utility model since at spool shaft rear suit one the rotation feed feeder; and the diameter of rotation feed feeder is to I haven't seen you for ages greater than spool shaft; therefore this is the feed feeder of a super-large diameter; supply water in a large number by the cooling water hole of rotation feed feeder in spool shaft; make cooling water by the breathing end of spool shaft rear one through to the spool shaft front portion; constantly fanning strip and spool shaft are cooled off by inside; the quality of product and the raising of production efficiency there is very positive meaning, simultaneously the service life of energy significant prolongation reel.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the amplification view of Fig. 1 along the A-A line.
Fig. 3 is the C portion enlarged drawing of Fig. 1.
The specific embodiment
From Fig. 1-Fig. 3 as can be seen, the utility model still has spool shaft 1, rear in spool shaft also is equipped with a rotation feed feeder 2, rotation feed feeder 2 has fixed cover 3, there is bearing 4 at two ends in the fixed cover, the centre has annular supply flume 5, the both sides of this annular water tank respectively are provided with two seals circle (6,7), wherein sealing ring 6 adopts composite rim, sealing ring 7 adopts the lip-type seal circle of withstand voltage and anti-high speed, one annular sluicing groove 8 is arranged between sealing ring 6 and the sealing ring 7, fixed cover 3 is provided with inlet opening 9 and osculum 10, inlet opening 9 is communicated with annular supply flume 5 and is used for sending for it water, and osculum 10 is communicated with annular sluicing groove 8 and is used for draining for it, guarantees that lip packing bears the higher pressure of system.Have a cooling water hole 11 in the spool shaft, this Kong Yiduan is connected with annular supply flume 5, the other end one is through to the breathing end 12 of spool shaft, cooling water 9 flows to annular supply flume 5 from the inlet opening, flow to cooling water hole 11 then and flow out from reel breathing end at last, parts such as fanning strip 13 and spool shaft 1 are cooled off.
