Description

A kind of tilting gear

Technical field

The present invention relates to the rolling machinery field, specifically a kind of on rollgang to the overturn tilting gear of operation of the steel billet of two ends warpage.

Background technology

For carrying amount of warpage larger rectangular bloom in two ends sideslip to occur, skid on charging roller table before current bar heating furnace, even can't transmission etc. phenomenon, need this moment manually the steel billet upset or hang roller-way, whole process is time-consuming but also effort not only; If the steel billet of roller transport hot charging carries out manual intervention and also exists larger security risk.If the processing of said process is completed by machinery, certainly will be not only safely but also raise the efficiency.It is reported and thisly enter the stokehold machinery that steel billet overturns was not also used, but the machinery that a kind of aftertreatment steel billet of coming out of the stove is arranged, as " blooming mill rhombus tilting gear ",, then the steel billet clamping is flipped an angle by one group of leverage as propulsion source with hydro-cylinder.It is larger that this turns over base machine structural style, and more complicated, takies than large space.

Summary of the invention

For carrying the two ends amount of warpage than the large rectangle base on charging roller table before present bar heating furnace, cause and manually turn over steel or hang roller-way, whole process is not only time-consuming but also require great effort, particularly the hot charging steel billet is carried out manual intervention and have larger security risk, for improving workman's operating environment, guarantee the process furnace rhythm of production, the invention provides a kind of online with 90 ° of the steel billet upsets of two ends warpage or the 180 ° device of 270 ° even, the steel billet smooth delivery of power is entered the tilting gear of stove, its compact construction is simple, take up room little, rushing to summit by the bottom surface, to turn over steel fast and reliable.

in order to achieve the above object, technical scheme of the present invention is: a kind of tilting gear, comprise hydro-cylinder, the low speed master wheel, slow-speed shaft, the low speed crank, low speed pinion, tunnel shaft, the high speed master wheel, the high speed shaft pinion, the high speed crank, connecting rod, gear wheel, the wheel of rushing to summit, flip-arm, base, it is characterized in that: described hydro-cylinder afterbody is hinged on base, head and low speed crank are hinged, low speed crank and low speed master wheel are with being contained on slow-speed shaft, the engagement of low speed master wheel and low speed pinion forms first step accelerating gear pair, low speed pinion and high speed master wheel are with being contained on tunnel shaft, the engagement of high speed master wheel and high speed shaft pinion forms second stage accelerating gear pair, high speed crank and the coaxial assembling of high speed shaft pinion, connecting rod one end and high speed crank are hinged, the other end and flip-arm are hinged, the wheel of rushing to summit is hinged on flip-arm.Two pairs of geartransmissions of every cover turnover form an acceleration machine, make the lower surface of the wheel rapid aerating-holding steel billet of rushing to summit, and make the steel billet of warpage realize 90 ° of upsets fast; The purpose of rapid aerating-holding is to prevent that steel billet from sliding on roller-way, and namely during rapid aerating-holding, steel billet also has little time to slide just to have overturn and puts in place, that is to say in the process of rushing to summit at a slow speed the steel billet certain distance that may slide on roller-way.The speed of rushing to summit can be regulated by the piston rod speed that flow valve is controlled hydro-cylinder.

Because steel billet reaches several meters, so tilting gear of the present invention comprises at least two identical turnovers of cover, two cover turnovers keep synchronism by shaft coupling 15.Hydro-cylinder 1 promotes low speed crank 4, and by two-stage accelerating gear pair, connecting rod 10 pulls the counterclockwise fast rotational of flip-arm 13, the wheel 12 of rushing to summit contacts steel billet and rapid aerating-holding steel billet under the roller-way face,, and make it around at least 45 ° of lower-left seamed edge rotations, steel billet will be reversed 90 °; The wheel 12 of rushing to summit rolls around stationary shaft, to avoid scratching billet surface in turning over the steel process.

The invention has the beneficial effects as follows, solved the problem that steel billet enters stokehold adjustment upset normotopia, raise the efficiency, guarantee safety, its compact construction is simple, takes up room little, and rushing to summit by the bottom surface, to turn over steel fast and reliable.
