Abstract
The invention discloses a hydraulic centering device, in particular a hydraulic centering device for preventing strip material from moving along the horizontal direction in the strip material rolling process. The hydraulic centering device is characterized in that the device comprises a pedestal and two bosses on the pedestal. The two bosses are arranged oppositely, and oil cylinders are arranged on the outer side of the bosses. The oil cylinders are arranged on the same axial line, and the piston rods of the oil cylinders respectively protrude inside corresponding bosses at the end section. Movable plates are arranged on the inner side of the two bosses, shaft holes are arranged on the lower section of the movable plates, and the piston rods are fixedly connected with the movable plates through nuts and the shaft holes. Both the movable plates have vertical shafts, and the two vertical shafts have guide wheels. The hydraulic centering device can improve the rolling quality and the rolling efficiency of the strip material.
Description
Technical field
The present invention relates to the milling train corollary equipment.Specifically, be the hydraulic pressure centralising device that prevents band along continuous straight runs move left and right in the rolled strip process.
Background technology
All know in milling train production and application industry,, the longitudinal centre line of band is on the roll surface center of double-working all the time for guaranteeing the rolling quality of band.For the longitudinal centre line that guarantees band is on the roll surface center of double-working all the time, conventional method is that the gag piece is set on the frame at operation roll of mill two ends.Can realize by the centering of strip though the gag piece is set on the frame at operation roll of mill two ends,, easily make by strip both sides plucking because the gag piece maintains static.And band is in case by plucking, also can make roll by plucking.Therefore, employing is provided with the gag piece and carries out centering, can reduce the rolling quality of band.In addition,, during the band of rolling different size, need to shut down and change the gag piece because the gag piece is fixed on the frame at operation roll of mill two ends, not only change cumbersome, and can influence of rolled efficient.
Summary of the invention
The problem to be solved in the present invention provides a kind of hydraulic pressure centralising device.Use this hydraulic pressure centralising device, can improve the rolling quality and the rolling efficiency of band.
For addressing the above problem, take following technical scheme:
Hydraulic pressure centralising device characteristics of the present invention are to contain base, and two boss are arranged on the base.This two boss is positioned opposite, and all there is oil cylinder in their outside.Described two oil cylinders are on the same axis, and their piston rod end is stretched into corresponding boss inboard respectively.All there is movable plate two boss inboards, and axis hole is arranged at the movable plate bottom, and the piston rod end is connected with movable plate with axis hole mutually by nut.Vertical shaft is all arranged at two movable plate tops, and guide wheel is all arranged on two vertical shafts.
Described boss is a tabular, and they are to erect arranges that the axis hole of their bottoms all has three, and these three axis holes are on the same level, and wherein Zhong Jian axis hole matches with piston rod.Two guide rods are all arranged between two movable plates and two boss, and the inner end of two guide rods is separately fixed in two axis holes of both sides, movable plate bottom, and the outer end of two guide rods is respectively in the axis hole that the slip shape stretches into the boss both sides.
Rectangular opening is all arranged at the top of two movable plates, on the upper and lower hole wall correspondence position of rectangular opening axis hole is arranged all, and the vertical shaft two ends are separately fixed in the axis hole on the upper and lower hole wall.
Take such scheme, have the following advantages:
Because hydraulic pressure centralising device of the present invention contains base, and two boss are arranged on the base.This two boss is positioned opposite, and all there is oil cylinder in their outside.Described two oil cylinders are on the same axis, and their piston rod end is passed corresponding boss inboard respectively.All there is movable plate two boss inboards, and axis hole is arranged at the movable plate bottom, and the piston rod end is connected with movable plate with axis hole mutually by nut.Vertical shaft is all arranged at two movable plate tops, and guide wheel is all arranged on two vertical shafts.During work, hydraulic pressure centralising device of the present invention is installed in charging one side of milling train, is introduced into by strip between two guide wheels of hydraulic pressure centralising device of the present invention, enters between two working rolls of milling train again.Flexible by two oil cylinder piston bars, can drive two movable plates and on guide wheel carry out move left and right, adjust on the roll surface center of double-working thereby make by strip, realize by the centering of strip.Can rotate along vertical shaft owing to guide wheel again, thereby avoid having been improved the rolling quality of band by the plucking of the plucking at strip edge and operation roll of mill roll surface.In addition, the flexible guide wheel move left and right that can make movable plate and top thereof owing to by the oil cylinder piston bar has realized the automatic adjustment of spacing between two guide wheels.When the rolling strip material with different width of need, by the flexible spacing that just can regulate between two guide wheels of hydraulic stem, not only adjusting is got up than being easier to, and need not shut down, and can improve rolling efficiency.
