Technical field
The utility model belongs to the rolling of metal, relates in particular to the aligning that is specifically designed to the metal rolled piece, sets upright and guiding, positioner.
Background technology
Two roller horizontal mills are milling train forms of generally using in line, the bar mill, roll pass during this type of milling train is thick and generally adopt ellipse-circle or oval-square passes, it when rolled piece goes out oval groove horizontal ellipse, be long axis of ellipse in the horizontal direction, minor axis is in vertical direction, and rolled piece need turn over and turn 90 degrees when entering down passage, enters square groove or circular hole with upright ellipticalness, promptly Tuo Yuan minor axis in the horizontal direction, major axis is in vertical direction.At present, be to adopt in oval groove frame outlet to reverse guide and guard and rolled piece is turned over turn 90 degrees, at circular hole or square groove frame the inlet guide and guard are installed, the elliptical rolled piece of upset is vertically sent into circular hole or square groove.The guide and guards that adopts is made of casing, a pair of vertical guide roll, guide plate and the cooling nozzle that are located on the casing.The major axis of elliptical rolled piece should be straight and be entered in circular hole or the square groove with plumbness in theory, but in actual production process, because workpiece front end distortion, or reverse the wearing and tearing of guide and guard, rolled piece often enters rolling guide with heeling condition, and its defective is that the rolled piece that tilts has the great impact effect to the guide and guard deflector roll, makes deflector roll or bearing cracked, guide and guards damages, and heap steel accident occurs; The inclination rolled piece is returned axial reaction force of top and bottom rolls, and this axial reaction force continuous action can make the roll dislocation, and the rolled piece that causes the circular hole frame to shut out is not round, very easily causes the quality of lot accident.
Summary of the invention
In order to overcome the shortcomings and deficiencies that prior art exists, the purpose of this utility model is to provide a kind of hot-rolled elliptical rolled piece on-line straightening device, elliptical rolled piece is carried out on-line straightening, the elliptical rolled piece major axis enters circular hole or square groove with plumbness, reduce the quality accident that the roll dislocation causes, reduce the generation of heap steel accident, reduce the guide and guards loss.
Hot-rolled elliptical rolled piece on-line straightening device, comprise casing, establish the rolled piece passage in the casing, guide plate is connected mutually with the rolled piece passage, and casing is established cooling nozzle, guide roller axis is established oilhole, oil nozzle, be characterized in that the deflector roll that a pair of axis crosses one another is set on the casing at least, and two roll axis angles are 2 α, the deflector roll of two band cambered surface passes stretches into the both sides of rolled piece passage obliquely, constitutes the sub-elliptical pass.
Two the deflector roll axis angle of the crossing 2 α are the 30-70 degree; Especially be good with the 20-50 degree.
The utility model further improves, and the casing front end is established screw, pin hole, casing is fixed on the rear end of circular hole import guide and guard by bolt and latch; Two sidewall front ends of casing are provided with through hole, the sloping platform of stationary guide roller axle, and sloping platform is established axis hole, and last sloping platform is also set a screw, guide roller axis is fixed on the sloping platform by clamp nut, bolt, deflector roll is fixed in the through hole, and the deflector roll of two band cambered surface passes crosses one another, and constitutes the sub-elliptical pass; Box back is established fixing bell-mouthed through hole and pin hole, and horn mouth is fixed in the through hole by latch, is connected mutually with the big chamfering of rolled piece passage.
Guide roller axis is eccentric shaft or d-axis.Cambered surface pass deflector roll is fastened on the guide roller axis by bearing, bearing cap; Guide roller axis upper end evenly is provided with the locating hole of adjusting wheelbase, by bolt the guide roller axis upper end is fixed on the sloping platform of casing, selects different locating holes, and spacing that just can two deflector rolls of online adjustment is to adapt to the rolled piece of different size.
During use, casing is assembled to circular hole or square groove import guide and guard rear portion, fixes by connecting bolt and latch.When the rolled piece of distortion passes through the sub-elliptical pass, the left side deflector roll gives its dextrad active force, the right side deflector roll gives its left-hand active force, to rolled piece align, clamping and correction, make its major axis enter the circular hole or the square groove of inlet guide and guards and rolling mill roll, be rolled smoothly with plumbness.Its advantage is that the minimizing rolled piece has reduced the consumption of deflector roll and the time of replacing guide and guards, favourable production to the impact of guide and guard; Reduce the generation of roll dislocation and heap steel accident, helped improving the product percentage of A-class goods.
