Wherein, the roller footpath scope 400-450mm of described the first working roll group, the first backing roll group maximumRoller footpath scope 900-1000mm;
The roller footpath scope of described the second working roll group is 450-500mm, the second backing roll group roller footpath scopeFor 900-925mm.
Can find out by foregoing, be the expansion of roller footpath scope by two rollers, lifting roll-forceAdjustable range greatly promotes the adjustable range of roll-force on existing basis; By two rollers footpath working rollThe hardware configuration of group provides the adaptability that effective basic framework is realized roll-force to regulate, to tackle notWith the roll-force demand of steel grade.
In order better to understand technique scheme, below in conjunction with Figure of description and concrete realityThe mode of executing is elaborated to technique scheme, is to be understood that the utility model embodiment and realityThe specific features of executing in example is the detailed explanation to present techniques scheme, instead of to the application's skillThe restriction of art scheme, in the situation that not conflicting, the technology spy in the embodiment of the present application and embodimentLevy and can mutually combine.
Referring to Fig. 1, a kind of polishing machine with two working rolls, comprising: the first working roll group (4,5),The first backing roll group (3,6), the second working roll group, the second backing roll group, frame 1, stepped plate 2,Hydraulic cylinder 7 and auxiliary hydraulic system and controller;
The first working roll group and described the first backing roll group are fixed in the described frame of polishing machine, described inThe first backing roll group supports described the first working roll group;
Described the second working roll group and described the second backing roll group are fixed in polishing machine frame, and describedTwo backing roll groups support described the second working roll group;
Described stepped plate is fixed in described frame, is resisted against the top working roll of described the first backing roll groupAnd directly over the upper backup roll of described the second backing roll group, dancer rools position;
Described hydraulic cylinder respectively with the lower backing roll of the lower backing roll of described the first backing roll group and described inThe lower backing roll of the second backing roll group is connected, and applies upwards roll-force;
Described hydraulic cylinder is connected with described hydraulic booster system, obtains hydraulic-driven power;
Described controller is connected with described hydraulic booster system, controls its action;
Wherein, the roller footpath scope 400-450mm of described the first working roll group, the first backing roll group maximumRoller footpath scope 900-1000mm;
The roller footpath scope of described the second working roll group is 450-500mm, the second backing roll group roller footpath scopeFor 900-925mm.
The roll-force scope 1000KN～5000KN of the second working roll group.
The second working roll group and the second backing roll group and the first working roll group, the first backing roll group are corresponding,With it side by side. With stepped plate 2 and the hydraulic cylinder 7 of frame, select according to the actual requirements differential roller system.
Described frame 1 is as polishing machine framework, and stepped plate 2 and hydraulic cylinder 7 etc. is arranged on 1 li of frame,Described stepped plate 2 is fixed on frame 1 top, join with two tops backing up roll, two top working rolls withCorresponding top backing up roll joins, and direct contact zones steel 8 upper surfaces, and two bottom working rolls directly contactBand steel 8 lower surfaces also join with lower support roll, and two lower backing rolls are connected with hydraulic cylinder 7, pass through liquidCylinder pressure provides roll-force upwards.
This polishing machine utilizes the gap between roll and the maximum row of hydraulic cylinder in frame to greatest extentJourney. First according to bracket height, the originally maximum functional stroke counter of the maximum gauge of roll and hydraulic cylinderCalculate the maximal work roller diameter that this polishing machine allows.
For example polishing machine bracket height is 3210mm, and former maximum functional roller roller footpath is 450mm, maximumBacking roll roller footpath is 1000mm, stepped plate minimum constructive height 135mm, memorial archway when polishing machine is opened completelyInterior maximal clearance is 175mm. Bottom working roll upper surface is apart from band steel lower surface 40mm, and top working rollLow spot is apart from band steel upper surface 75mm, and the distance at upper working rolls and lower working rolls bearing block center is fixed as 565mm.When work roll bending is opened so, the distance between two working rolls is 115mm, for ensureing normally to rollSteel, while opening soon, between working roll, minimum gap is 65mm, the polishing machine maximum functional roller roller allowing soFootpath is 500mm, the big roller footpath 925mm of backing roll. Like this, the big roller of polishing machine working roll footpath by450mm becomes 500mm, and working roll footpath allowed band is 450-500mm, backing roll roller footpath modelEnclose for 900-925mm.
The work of what the utility model embodiment provided the have polishing machine of the big roller of two working rolls footpath systemPrinciple is as follows: in the time producing common steel grade, the required roll-force of polishing machine is little, also uses original workMake roller and backing roll, when the high special steel grade of production roll-force, select by button, switch relevant controlParameter processed, can be used more big roller footpath working roll to be rolled.
The impact of differential roller footpath on roll-force before and after transformation:
Use as can be seen from the above table behind large working roll roller footpath roll-force to increase obvious, and needAsk the roll-force that can reach behind the new roller of the larger use of roll-force footpath also larger, can meet the many steel of rollingThe demand of kind.
The one or more technical schemes that provide in the embodiment of the present application, at least have following technique effectOr advantage:
The polishing machine with two working rolls providing in the embodiment of the present application, adopting two rollers is polishing machine knotStructure, expands roll-force adjustable range, to adapt to the demand of different steel grade roll-forces; By two roller tyingsStructure significantly promotes roll-force, promotes the operating efficiency of polishing machine.
It should be noted last that, above detailed description of the invention is only in order to illustrate technology of the present utility modelScheme and unrestricted, although the utility model is had been described in detail with reference to example, this area generalLogical technical staff should be appreciated that can the technical solution of the utility model be modified or is equal to and replacesChange, and do not depart from the spirit and scope of technical solutions of the utility model, it is new that it all should be encompassed in this practicalityIn the middle of the claim scope of type.
