Description
Technical field
The present invention relates to mechanical equipments, more particularly to a kind of holding-down device of hydraulic for milling train.
Background technology
Milling train is the important mechanical equipment of rolling metal processing, and the screw-down of milling train is the important adjustment machine of whole milling train
Structure, there are two types of traditional screw down mechanism of rolling mill：One is driving lead screw to depress by second-stage worm gear worm speed-down using motor, separately
One is directly being depressed with large_sized hydraulic cylinder, the problem is that：The first huge structure, precision are low.Second of structure is multiple
Miscellaneous, cost is high.
Invention content
The purpose of the present invention is exactly to solve the above-mentioned problems, to provide a kind of holding-down device of hydraulic for milling train.
In order to achieve the above object, present invention employs following technical schemes：A kind of holding-down device of hydraulic for milling train,
In rack and it is arranged on the bearing block of milling train topping roll；Including Wedge-type oil cylinder, which includes voussoir
Formula cylinder body, two Cylinder Plungers and two sealing elements, interior be equipped with of Wedge-type cylinder body control two oil pockets, and the one of two Cylinder Plungers
End is slided over respectively in two oil pockets in left and right, and the other end of two Cylinder Plungers is respectively fixed on the machine frame, plunger and cylinder body it
Between sealed with sealing element；The lower surface of Wedge-type cylinder body is inclined-plane, and the upper surface of the bearing block of corresponding topping roll is oblique
Face；Topping roll is pushed by the realization that moves left and right of Wedge-type cylinder body.
