Abstract
A hydraulic screwdown gear for a rolling mill comprises a wedge type oil cylinder, wherein the wedge type oil cylinder comprises a wedge type cylinder body, two oil cylinder plungers and two sealing elements; a left oil cavity and a right oil cavity are formed in the wedge type cylinder body; one ends of the two oil cylinder plungers are respectively inserted in the left oil cavity and the right oil cavity slidably; the other ends of the two oil cylinder plungers are respectively fixed on the rack; each plunger and the cylinder body are sealed by the corresponding sealing element; the lower surface of the wedge type cylinder body is an inclined surface; the upper surface, which corresponds to the lower surface of the wedge type cylinder body, of a bearing block of an upper roller is an inclined plane; and pushing of the upper roller is realized by left-right movement of the wedge type cylinder body. The hydraulic screwdown gear for the rolling mill has the advantages of simple structure, stable work, high precision and the like.
Description
Technical field
The present invention relates to plant equipment, particularly a kind of holding-down device of hydraulic for milling train.
Background technology
Milling train is the important plant equipment of rolling metal processing, the screw-down of milling train is the important guiding mechanism of whole milling train, traditional screw down mechanism of rolling mill has two kinds: one utilizes motor to drive screw mandrel pressure through second-stage worm gear worm speed-down, another kind directly depresses with large_sized hydraulic cylinder, its Problems existing is: the first huge structure, precision is low.The second complex structure, cost is high.
Summary of the invention
Object of the present invention, exactly in order to solve the problem, provides a kind of holding-down device of hydraulic for milling train.
In order to achieve the above object, present invention employs following technical scheme: a kind of holding-down device of hydraulic for milling train, to be arranged in frame and to be arranged on the bearing block of milling train topping roll; Comprise Wedge-type oil cylinder, this Wedge-type oil cylinder comprises Wedge-type cylinder body, two Cylinder Plungers and two seals, two oil pockets in left and right are provided with in Wedge-type cylinder body, one end of two Cylinder Plungers slides in two oil pockets in left and right respectively, the other end of two Cylinder Plungers is separately fixed in frame, seals between plunger and cylinder body with seal; The lower surface of Wedge-type cylinder body is inclined-plane, and the upper surface of the bearing block of topping roll corresponding is with it inclined-plane; Realize topping roll to press down by moving left and right of Wedge-type cylinder body.
Between Wedge-type oil cylinder and the bearing block of described topping roll, be provided with lower friction plate, between the upper surface and frame of Wedge-type oil cylinder, be provided with friction plate.
Also comprise displacement transducer, this displacement transducer is arranged on the side of the bearing block of described topping roll.
The present invention is used for the holding-down device of hydraulic of milling train, has that structure is simple, working stability, precision advantages of higher.
