Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig.1 shown in, a kind of small roller diameter six-high cluster mill, roller system assembly by top backing up roll assembly 1, upper intermediate calender rolls assembly 2,
Top working roll assembly 3,6 composition of bottom working roll assembly 4, lower intermediate calender rolls assembly 5 and lower support roll assembly.Upper intermediate calender rolls assembly 3
And lower intermediate calender rolls assembly 5 is live-roller.
Two methods improve working roll axially loaded situation.First, work is reduced by the method for monoblock type roll-bending device
Make the axial angle of the crossing of roller and intermediate calender rolls.Second, nitrogen gas spring applies pretightning force, balances out the axial direction of effect on the work rolls
Power.It is specific as follows:
As shown in Figures 1 and 3: the axial angle of the crossing between backing roll, intermediate calender rolls and working roll makes each roll bear axis
Xiang Li.But the axial force that the angle of the crossing between backing roll and intermediate calender rolls generates is all by stopping in backing roll and intermediate calender rolls assembly
Thrust bearing is born, and since backing roll, intermediate calender rolls are relatively large in diameter, their thrust bearing is able to bear biggish axial direction
Power, and will not conduct to working roll.Therefore, axial force on the work rolls and roll-force and working roll and centre are acted on
The axial angle of the crossing of roller is related.As long as reducing the axial angle of the crossing of working roll and intermediate calender rolls, so that it may which reduction acts on minor diameter
Axial force on working roll.
Traditional six-high cluster mill working roll bending cylinder block, intermediate calender rolls bending cylinder block are all separately mounted in rack, intermediate
Roll bending cylinder block also needs axial float with respect to rack, and many copper shoes are needed between cylinder block and rack.And each intermediate calender rolls
Liner plate is fitted on bending cylinder block, each working roll bending cylinder block.Due to adding for each bending cylinder block, copper shoe and liner plate
The cumulative limit of work and fixing link axially intersects than more serious so as to cause working roll and intermediate calender rolls axis.And it is of the invention
The middle design using monoblock type roll-bending device, roll-bending device 11 is by upper intermediate calender rolls bending cylinder block 11-1, working roll bending cylinder block 11-
2, lower intermediate calender rolls bending cylinder block 11-4 and fixed block 11-3 composition.It is characterized in that, upper intermediate calender rolls bending cylinder block 11-1, work
Roll bending cylinder block 11-2, lower intermediate calender rolls bending cylinder block 11-4 are installed on fixed block 11-3.Upper intermediate calender rolls bending cylinder block 11-1,
It is all made of no copper shoe on working roll bending cylinder block 11-2, lower each cylinder block of intermediate calender rolls bending cylinder block 11-4 and is designed without liner plate,
Roll-bending device can be used as an entirety, via fixed block 11-3 integral installation in rack 10.It thus can be each roller
Cylinder block is processed, checked and is assembled as a part, in this way can by monoblock type roll-bending device with bearing block slide plate
Monoblock type roll-bending device then need to only be assembled 11 in machine within 0.01mm by the form tolerance control between each face of cooperation
On frame 10, assembly precision greatly improved, so that the axial angle of the crossing of working roll and intermediate calender rolls becomes very small, this
In the case where roll-force is constant, the axial force acted on the work rolls also greatly reduces sample.
As shown in Figure 4: top working roll assembles 3 two sides and is axially held out against by fore side axial direction holding device 7 and transmission side respectively
Device 8, which applies certain pretightning force, to be withstood.The 3 all structures in the left and right sides of top working roll assembly are using milling train center line as line of symmetry
Symmetrical: wherein side is by top 3-1, pressing plate 3-2, one 3-3 of transparent cover, tapered roller bearing 3-4, needle bearing 3-5, work roll shaft
Hold a 3-6, working roll 3-7, two 3-8 of transparent cover, one 3-9 of slide plate and two 3-10 of slide plate composition；Other side also has corresponding top
The structures such as head, pressing plate, transparent cover, tapered roller bearing, needle bearing, working roll bearing block, slide plate, and it is symmetrical with it.With circular cone
The bearing outer ring both ends of roller bearing 3-4 are fixed on working roll bearing block 3-6 by one 3-3 of transparent cover and two 3-8 of transparent cover respectively.
The bearing inner race both ends of tapered roller bearing 3-4 are fixed by the shaft shoulder of working roll 3-7 and pressing plate 3-2 respectively.Workroll bearing
Seat 3-7 is fixed on working roll bending cylinder block 11-2 by working roll bearing block jam plate 9.
As shown in Fig. 2 Fig. 5: axial holding device 7 is fixed on working roll bending cylinder block 11-2.Fore side axially holds out against dress
7 are set to be made of nitrogen gas spring 7-1, crossbeam 7-2, eccentric pin shaft 7-3 and locking jackscrew 7-4.Nitrogen gas spring 7-1 is fixed on crossbeam
On 7-2.When eccentric pin shaft 7-3 is rotated, crossbeam can be deviated in the range of eccentric adjusting amount, so that nitrogen gas spring 7-1
Center line alignment work roll axis and withstand always.Side axle is to 8 structure of holding device and 7 knot of fore side axial direction holding device
Structure is identical.The both ends for respectively having a nitrogen gas spring to withstand on working roll 3-7 are controlled in this way.
Top working roll assembly two sides are withstood using fore side axial direction holding device 7 and transmission side axial direction holding device 8, it can
Balance out the axial force of a part effect on the work rolls: axial due to having between double row tapered roller bearing inner ring and outer ring
Clearance, working roll bearing block jam plate and working roll bearing block are also having gap in working roll axially direction, therefore work as work
When roller is by axial force, since two sides fore side axial direction holding device 7 and transmission side axial direction holding device 8 have withstood work
Roller, therefore axial force is acted on first on the nitrogen gas spring of axial holding device.The pretightning force of nitrogen gas spring top on the work rolls
It can be set by adjusting nitrogen pressure.With the increase of axial force, after reaching pretightning force, axial force, which is further continued for increasing, to be made
It obtains nitrogen gas spring to compress and retract, more than after the sum of bearing axial play and jam plate gap, axial force can just act on decrement
In double row tapered roller bearing, and it is finally transmitted to rack.Structure of the invention is balanced out by the pretightning force of nitrogen gas spring
The axial force of a part effect on the work rolls, therefore the axial force born required for double row tapered roller bearing significantly subtracts
It is small, improve the service life of bearing.
Two methods improve working roll horizontal force situation: first, the relatively upper intermediate calender rolls center line of working roll center line
There is an offset, then under the action of roll-force, the horizontal component of roll-force can be passed with roll torque to a certain extent
The horizontal component for passing generation is offset.Second, using no inner-ring bearing, increase the diameter at working roll roll neck.It is specific as follows:
The 3 all structures in the left and right sides of working roll assembly are symmetrical using milling train center line as line of symmetry.One 3-9 of slide plate and slide plate
Two 3-10 thickness are different, so that the relatively upper intermediate calender rolls of working roll 3-7 center line assemble 2 center lines with working roll 3-7 center line phase
2 center lines are assembled to upper intermediate calender rolls and milling train window center line is not overlapped, there is an offset.One 3-9 of slide plate and two 3- of slide plate
Different thickness differences can generate different size of offset between 10.And working roll assembly 3 rotates 180 degree in the horizontal plane
Afterwards, the relatively upper intermediate calender rolls of working roll 3-7 center line assemble 2 disalignment directions and original on the contrary, offset size and original
It is constant.
In order to further increase the horizontal force that minor diameter working roll is able to bear, the present invention using no inner ring transverse bearing,
Working roll roll neck is as bearing inner race.No inner ring transverse bearing selects needle bearing 3-5, and this bearing roller size is very
It is small, and the method without inner ring can increase the diameter at working roll roll neck to the greatest extent.Working roll bending resistance and diameter
Cube is directly proportional.The heat treatment of working roll roll neck is core soft flexible, Surface hardened layer.Bearing roller can either be met upper
The requirement that face rolls, while bending resistance and impact resistance at roll neck can be increased.
Especially, it should be noted that in order to be applied in the range of different operating roller is with intermediate calender rolls eccentric adjusting amount to working roll
Add pretightning force, axial holding device design has eccentric pin shaft 7-3, and eccentric pin shaft rotation enables crossbeam deviating, so that nitrogen
The center line of gas spring alignment work roll axis and is withstood always.
It is respectively two sets that top backing up roll assembly 1 and lower support roll, which assemble 6 quantity, wherein the axis of a set of upper and lower backing roll assembling
It is larger to hold clearance, precision is relatively low；The bearing clearance of the upper and lower backing roll assembling of other set is smaller, and precision is relatively high.Bearing
The biggish thick material of backing roll assembling rolling of clearance, is able to bear big load and big calorific value；The lesser backing roll of bearing clearance
Assembly rolls thin material, and Product Precision is high；If the thin material of reproduction, needs replacing backing roll after mass production thickness material；And it produces
If continuing to produce thick material after complete thin material, replacement backing roll is not needed.
