Steel plate pressing guide device

Abstract

The invention discloses a steel plate down-pressing guiding device which comprises a main rolling mill shell, wherein a transversely arranged conical slot is formed in the main rolling mill shell; an oil cylinder is mounted at the top of the main rolling mill shell; a piston rod of the oil cylinder extends into the main rolling mill shell to reach an upper supporting seat; a spherical supporting rod is mounted at the lower part of the upper supporting seat through a support and is fixedly connected with the head of the piston rod; a roller and a pressing plate are also mounted at the bottom of the support; a base is arranged on a lower supporting seat; symmetrically arranged guiding mechanisms are mounted on the base at an interval; each guiding mechanism comprises a sliding plate; a square slot is formed in the middle part of the sliding plate; a square block is mounted in the square slot; two side surfaces of the square block are in tight contact with the square slot; a threaded hole is formed in the middle part of the square block; a screw rod penetrates through the threaded hole; a roller seat is fixed on the side surface of the sliding plate; a plurality of rollers are mounted on the roller seat at intervals; a nylon plate is also mounted at the middle part on the upper surface of the base; two sides of the nylon plate are respectively clamped with nylon fixed plates through fastening pieces; a clearance is reserved between the nylon plate and the pressing plate. The steel plate down-pressing guiding device is high in working reliability.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for rolling mills, in particular to a steel plate pressing guide device. Background technique [0002] In metallurgical production, when the rolling mill equipment is working, the roll system is generally composed of backup rolls, intermediate rolls, work rolls, etc., which is an important part of the rolling mill equipment. The rolls in the roll system are always subject to changes in direction and size. rolling force effect. If the steel plate entering the rolling mill is warped or the surface is uneven, the rolls in the rolling mill will be damaged. The centering of the steel plate is directly related to the service life of the rolls, and it will also cause the steel plate to deviate during the coiling process or break phenomenon. Contents of the invention [0003] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a steel p...
