The utility model relates to a hydraulic driving guide device used for a cold rolling mill; the hydraulic driving guide device is characterized in that a hydraulic motor is fixed on a base, a screw rod is supported on a bearing seat through a tapered roller bearing, and both ends of the screw rod are positioned via a bearing unclosed cover and a bearing stuffy cover; the hydraulic motor is connected with the screw rod through a connecting sleeve; and a left nut and a right nut which are matched with the screw rod are respectively screwed on the screw rod, symmetrically arranged and positioned in a guide groove on the base through pressing strips, and two guide wheels are respectively arranged on the left nut and the right nut and fixed on the left nut and the right nut via bolts and through a retaining ring for hole, a bearing, a guide wheel axle, a pressure plate and a connecting seat. The utility model has the advantages that the hydraulic driving guide device is simple, compact and reasonable in structure, low in manufacturing cost, convenient to use and easy to install and replaces the manual operation with the hydraulic motor, thereby reducing the labor intensity of the workers, improving the labor productivity and increasing the economic benefits.
Description
Technical field
The utility model relates to a kind of hydraulic driving guide device of cold-rolling mill, specifically a kind of novel guide device by fluid motor-driven of cold-strip mill in the metallurgy industry.
Background technology
At present, in cold-strip mill extensive use lead a mode have gag lead the position, manually adjust respectively roller lead the position etc.Which kind of mode no matter, when the width of band changed, adjusting was not that easily automaticity is low, all needs to operate manually, and working strength of workers is big, and production efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of hydraulic driving guide device of cold-rolling mill is provided, and replaces manual operations with hydraulic motor, can alleviate operator's labour intensity, can raise labour productivity.
The technical scheme that provides according to the utility model, the hydraulic driving guide device of cold-rolling mill, feature is to adopt hydraulic motor to be fixed on the base through support by bolt, the diaxon bearing is by being bolted on the base, screw mandrel is bearing on the bearing block through taper roll bearing, and two ends are by logical lid of bearing and bearing stifle location; Between hydraulic motor and the screw mandrel by the coupling sleeve transferring power that links; Left nut and the right nut supporting with screw mandrel are screwed on the screw mandrel, and symmetric arrangement is positioned in the gathering sill on the base by press strip simultaneously, and when screw mandrel rotated, left nut and right nut can only be made rightabout straight line along the axial line of screw mandrel and move; On left nut and right nut, two guide wheels respectively are set, guide wheel moves with nut by being bolted on left nut and the right nut with back-up ring, bearing, guide wheel shaft, pressing plate, Connection Block by the hole; Each guide wheel can rotate on guide wheel shaft, prevents guide wheel and band mutual friction mutually; Adjust the position of left nut and right nut, make distance between two side guide wheels equal the width of band, finish band centering, lead bit function.
Described screw mandrel is provided with the screw thread of two sections symmetries, and one section is right-handed thread, and another section is a left hand thread.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Low cost of manufacture, easy to install and use; Replace manual operations with hydraulic motor, alleviated operator's labour intensity, improved labor productivity, increased economic benefit.
