Abstract
The present invention provides a kind of new roller, roll is by roll mandrel, hydraulic cylinder is several, expansion cambered surface is several, 4 part of hollow cylinder is constituted, hydraulic cylinder is along the radial and axial arrangement of the roll mandrel regular polygon body of roll, each hydraulic cylinder external part connects firmly an expansion cambered surface, all expansion cambered surfaces are all close on the inside of hollow cylinder, and by hydraulic cylinder, axially distribution is in an axial direction separated into roll crown n sections.The hollow cylinder after abrasion can be dismantled and be replaced to roll, service life is long, maintenance cost is low, the present invention by roll axially each section hydraulic cylinder input fluid volume be adjusted, the axially distributed arbitrary convex value of hollow cylinder can be changed, control accuracy is high, can easily control roll loading roll gap shape, simplify the control process of milled sheet shape.
Description
Technical field
The invention mainly relates to board rolling fields, and in particular to a kind of new roller belongs to material processing plant.
Background technology
With the development of China's aviation industry, the plate shape of milled sheet band is required higher and higher.Milled sheet tape thickness is distributed
It is determined by working roll loading roll gap shape, continuous plate thickness distribution just constitutes plate shape, and influences roll loading roll gap shape
Factor it is numerous, substantially include deformation of rolled wire performance, supplied materials geometry, operation of rolling condition etc..Due to the operation of rolling
Middle parameter is numerous, and there are coupled relations between each parameter, while supplied materials internal cause hardly results in accurate model, therefore, to obtain
It is difficult to the plate thickness distribution in ideal.If roll gap shape can be adjusted directly, the adjusting of plate thickness distribution can be realized,
Change roll gap shape, by the original convexity of roll and roll thermal crown having before this by bending roller force change roll gap shape, by CVC rollers
Change the methods of roll gap shape, but since roll is longer, these methods all cannot fully control the plate along plate width direction each point
Thickness value.Therefore a kind of new roller design is necessary to plate thickness profile adjustment, it can change axial any position
Roll gap shape, to realize the adjusting of plate thickness distribution.
Invention content
Technical problem to be solved by the invention is to provide a kind of new roller, roll is by roll mandrel, hydraulic cylinder is several, expands
Cambered surface is several, hollow cylinder is constituted, and roll crown is separated into n sections by hydraulic cylinder in an axial direction, the hydraulic cylinder extension on every section
Amount directly affects the convex value of hollow cylinder by expanding cambered surface, and capable of adjusting roll well, convexity is distributed in an axial direction, to
Change roll gap shape when roll work, obtains ideal strip thickness distribution.
The technical solution that the present invention solves above-mentioned technical problem is as follows：A kind of new roller, roll mandrel support end are still protected
Cylinder is held, the installation and rolling of roll are conducive to, the roll mandrel body of roll is designed as regular polygon, along the installation pair of regular polygon periphery
Number of edges hydraulic cylinder is answered, n hydraulic cylinder is installed along roll mandrel axial direction, the hydraulic cylinder extension amount on each section is by expanding arc
Face is directly changed hollow cylinder convex value, and roll axial direction convexity is formd by the n convex value that hollow cylinder is axially distributed
Distribution, realizes the control of roll gap in the roll course of work, further realizes the control of milled sheet tape thickness distribution.
Further, the number of edges of regular polygon can be selected according to roll overall dimensions and operating condition.
It is possible to further which hydraulic cylinder mounting groove is arranged on the roll mandrel regular polygon body of roll, facilitate the positioning of hydraulic cylinder
And installation.
Further, hollow cylinder of the invention and expansion cambered surface select suitable material and thickness according to rolling condition
Degree.
Further, hollow cylinder can open up card slot at both ends and carry out axially position with roll both ends expansion cambered surface.
Further, hollow cylinder of the invention can easily replace one after the wear extent for reaching certain
New hollow cylinder.
The beneficial effects of the invention are as follows：The hollow cylinder after abrasion can be dismantled and be replaced to roll, and service life is long, dimension
Shield expense is low, and the board rolling for being suitable for the installation of any type of milling train and any material works, roll crown profile adjustment side
Just, roll gap shape impact analysis and modeling in rolling work are simplified, plate thickness distribution in plate strip rolling process is realized and precisely adjusts
Control, control process is simple, easily operated.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of new roller of the present invention.Fig. 2 is the transversal profile schematic diagram of roll.
In attached drawing, the names of the parts represented by the respective symbols are as follows：1, roll mandrel（1.1 roll mandrel support ends, 1.2 roll mandrels
The regular polygon body of roll）, 2, hydraulic cylinder it is several, 3, expansion cambered surface it is several, 4, hollow cylinder.
Specific implementation mode
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
As shown in Figure 1, a kind of new roller, including by cylindrical rollers axis support end 1.1, the support end 1.1 with roll
The roll shaft regular polygon body of roll 1.2 is an entirety, collectively forms roll mandrel 1,1.2 number of edges of the regular polygon body of roll can be according to specific
Condition is designed, and radial distribution is equipped on the regular polygon body of roll 1.2 and the hydraulic cylinder being axially distributed 2 is several, each hydraulic pressure
Cylinder external part, which is connected one, expands cambered surface 3, and all expansion cambered surfaces 3 are fitted closely with 4 inner cylinder face of hollow cylinder, axial every
Hydraulic cylinder 2 in section can pass through expansion by its stroke of how much changes of change input hydraulic pressure oil, the stroke of hydraulic cylinder 2
Cambered surface 3 is directly changed the convex value of hollow cylinder 4.The size of axial often place convex value is according to the needs in plate strip rolling process
It is adjusted.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, made by any modification, equivalent replacement etc., should all be included in the protection scope of the present invention.
