Abstract
The invention discloses a roller central line adjusting device, which comprises a frame. The device is characterized in that two lower wedges are arranged on the bottom of the window of the frame and are adjacent to each other at the tip ends with the inclined planes facing upwards. An installation board is arranged on the two lower wedges, three coaxial bearing pedestals are arranged below the installation board, and screws are arranged among the bearing pedestals. The screws penetrate through the three bearing pedestals with the aid of bearings and protrude out of the bearing pedestals on both sides at the two ends. One of the protruding ends is connected with a power mechanism. Upper wedges with longitudinal screw holes are arranged between two adjacent bearing pedestals and are screwed in the screws through the longitudinal screw holes, wherein the two longitudinal screw holes of the two upper wedges have opposite thread directions, the thick ends of the upper wedges are adjacent to each other, and the inclined surfaces of the upper wedges face downwards and are respectively in sliding contact with the two lower wedges. The device is used for adjusting the central line of rollers and has the advantages of power saving, time saving, lowered labor intensity and improved work efficiency and adjustment accuracy. The roller central line adjusting device is suitable for adjusting the working roller central line of a rolling mill.
Description
Technical field
The present invention relates to a kind of milling train corollary equipment.Specifically, be to be used for adjusting device that the working roll center line of milling train is regulated.
Background technology
Know all that in milling train manufacturing and application industry milling train is long running time one, the diameter of its roll can diminish, and makes that the center line between two rolls descends.Therefore, need often the center line between two rolls to be regulated.The tradition control method is after adopting manually bearing block with lower support roller two ends to lift, shell tool below bearing block and realizing.Though adopt this mode can realize that the center line between two rolls regulates, owing to need manually lift bearing block, not only time-consuming, effort, labour intensity are bigger, and inefficiency.Because employing cushioning pad below bearing block is realized the adjusting of center line between two rolls, and the thickness of pad, placement location all can influence degree of regulation, therefore, be difficult to harmonize again, degree of regulation is not high.
Summary of the invention
The problem to be solved in the present invention provides a kind of roll center line adjusting device.Use this device to come the center line of breaker roll to regulate, save time, laborsaving, can reduce labour intensity, increase work efficiency and degree of regulation.
For addressing the above problem.The present invention takes following technical scheme:
Roll center line adjusting device of the present invention contains organic frame, is characterized in that the window bottom of frame is fixed with two following wedges, and these twice wedges arrange along the direct of travel of band, they most advanced and sophisticated adjacent, and their inclined-plane is up.There is installing plate twice wedges top, is fixed with three bearing blocks below the installing plate, and these three bearing blocks are coaxial, and screw mandrel is arranged between them.Described screw mandrel penetrates in three bearing blocks by bearing, and all stretch out outside the bearing block of both sides at its two ends.One of them dynamic mechanism in overhanging end place, the output shaft of this actuating unit links to each other with an end of screw mandrel.Between two adjacent bearing blocks last wedge is arranged all, this all has vertical screw on wedge on two, and they are screwed on the screw mandrel by this vertical axis hole.Wherein, the hand of spiral of the vertical screw on two on the wedge is opposite, and their thick end is adjacent, and their inclined-plane is the slip shape and contacts down and respectively with between two following wedges.
Adopt such scheme, have following having a few:
Because roll center line adjusting device of the present invention, be fixed with two following wedges in the window bottom of frame, these twice wedges arrange along the direct of travel of band, they most advanced and sophisticated adjacent, and their inclined-plane is up.There is installing plate twice wedges top, is fixed with three bearing blocks below the installing plate, and these three bearing blocks are coaxial, and screw mandrel is arranged between them.Described screw mandrel penetrates in three bearing blocks by bearing, and all stretch out outside the bearing block of both sides at its two ends.One of them dynamic mechanism in overhanging end place, the output shaft of this actuating unit links to each other with an end of screw mandrel.Between two adjacent bearing blocks last wedge is arranged all, this all has vertical screw on wedge on two, and they are screwed on the screw mandrel by this vertical axis hole.Wherein, the hand of spiral of the vertical screw on two on the wedge is opposite, and their thick end is adjacent, and their inclined-plane is the slip shape and contacts down and respectively with between two following wedges.When need are regulated two roll center lines of milling train, make the screw mandrel rotation as long as start actuating unit, just can drive wedge vertically moving on two along screw mandrel.Contact owing to be the slip shape between the inclined-plane of two wedges and following wedge,, can make installing plate rising or decline when between last wedge and following wedge during along the vertically moving of screw mandrel.And the lower support roller of milling train is on the installing plate, and working roll is in again on the lower support roller., the rising of installing plate or decline, the backing roll and the working roll on the backing roll that can drive on it rise together or descend.Therefore,, just can realize the adjusting of operation roll of mill center line, not need manually both to have improved degree of regulation, can save the adjusting time again, improved operating efficiency, reduce labour intensity as long as start actuating unit.
Description of drawings
Accompanying drawing is a roll center line adjusting device structural representation of the present invention.
The specific embodiment
As shown in drawings, roll center line adjusting device of the present invention comprises frame 2.This frame is the frame of milling train, and its window bottom is fixed with two following wedges 8.Twice wedge 8 arranges that along the direct of travel of band their tip is that featheredge is adjacent, and their inclined-plane up.Twice wedge 8 tops are provided with installing plate 1, are fixed with three bearing blocks 7 below the installing plate 1, and these three bearing blocks are coaxial shape to be arranged, is provided with screw mandrel 10 between them.Described screw mandrel 10 penetrates in three bearing blocks 7 by bearing 5 respectively, and all stretch out outside the bearing block 7 in two outsides at its two ends.One of them overhanging end place is provided with actuating unit 6, and this actuating unit is a hydraulic motor, and its output shaft is connected mutually with an end of screw mandrel 10.7 adjacent of two bearing blocks are provided with wedge 9, this on two wedge vertically be that its featheredge all is processed with a vertical screw on the direction of webbing, they are screwed on the screw mandrel 10 by this vertical axis hole.Wherein, the hand of spiral of the vertical screw on two on the wedge 9 is opposite, and their thick end is adjacent, and their inclined-plane down and be the slip shape with two 8 of following wedges respectively and contact.Wherein, the vertical screw on the last wedge 9 is a first processing axis hole on last wedge 9, again hold-down nut and forming in axis hole.
