Description
Technical field
Patent of the present invention relates to a kind of roll location control method and device, and especially roll mandrel is to position adjustments method and apparatus.
Background technology
At present, the roll of general large-sized rolling mills all adopts dual-gripper, and two ends support or are all fixing, or is that one end supports and can move axially along roll, and one end supports in addition is fixing.Even if roll one end supports and can move vertically, roll axial location in working order still determined by its fixed support end, and roll duty axial location is also nonadjustable.For Parts with Special shaped Section roll forming, often need the axial location adjusting roll to meet the exact axial position demand of roll pass.The multiple shaping stage of some Parts with Special shaped Section roll forming process process need, roll pass required for each stage is different, if automatic fine adjustment can be carried out by the axial location of breaker roll work quickly and easily, just axially different for roll position can be arranged different passes, in ring rolling process, change roll axial location according to process requirements change roll pass, thus roll can not be changed just can complete Parts with Special shaped Section roll forming.For the roll forming of rectangular section part, often the work axial location of adjustment roll can make the wearing and tearing of roll in axially different position more even, improves the uniformity of roll external diameter, thus improves roll working life.
Summary of the invention
In order to the roll mandrel meeting part roll forming can be automatically accurately adjustable to operating position, patent of the present invention creates roll mandrel to position adjustments method and apparatus.
Patent of the present invention solves the technical scheme that its technical problem adopts: roll is provided with support set and lower support cover, roll and lower support cover are by pull bar fixed connection, roll and upper support set link joint, roll in working order time, roll inserts in upper support set, when part loading and unloading, roll is extracted out from upper support set.Upper support set can slide up and down in upper support seat, and lower support cover can slide up and down in lower support seat, and upper support set and lower support are enclosed within when moving up and down that it all has guiding all around, ensure that both centers can not change.Upper support set drives cylinder block to be contained on upper support seat, cylinder piston rod upward, piston rod front end and moving beam are by flange coupling, and moving beam, by support set connection on pull bar, gland and roll, can drive support set to slide up and down when this oil cylinder stretches.Multiple isometric locating dowel is installed under lower support seat, be provided with fixed head under locating dowel, lower support cover drives cylinder block to be arranged on fixed head, and cylinder piston rod upward, piston rod front end, by flange and the connection of lower support cover, can drive lower support cover to slide up and down when this oil cylinder stretches.Upper support set drives oil cylinder and lower support cover to drive oil cylinder to be equipped with stroke detection displacement transducer, therefore support set is gone up and lower support cover can accurately control along roll axial location, when needs regulate roll work axial location, upper support set drives oil cylinder and lower support cover to drive oil cylinder to need flexible corresponding stroke according to roll mandrel to change in location, roll in working order time all have good support up and down, ensure that the rigidity of roll device.More than be expressed as vertical roll mandrel to position adjustments method and apparatus, the method is equally applicable to horizontal roll axial location and regulates.
The beneficial effect of patent of the present invention can realize roll axial location by roll mandrel to position adjustments method and apparatus conveniently automatically to adjust, thus meet the exact requirements of part rolling mill practice breaker roll different operating axial location.
Below with reference to accompanying drawing, the present invention is described in further details.

Detailed description of the invention
As Figure 1-Figure 5, roll mandrel comprises moving beam 1, flange 2, pull bar A 3, gland 4, upper support drive oil cylinder 5, upper support set 6, upper support seat 7, roll 8, lower support cover 9, pull bar B 10, lower support seat 11, flange B 12, locating dowel 13, lower support driving oil cylinder 14 and fixed head 15 to position adjustments method device for carrying out said main parts size.
Roll 8 is provided with support set 6 and lower support cover 9, and roll 8 and lower support cover 9 pass through pull bar B 10 fixed connection, roll 8 and upper support set 6 link joint, roll 8 in working order time, roll 8 inserts in upper support set 6, and when ring loading and unloading, roll 8 is extracted out from upper support set 6.Upper support set 6 can slide up and down in upper support seat 7, and lower support cover 9 can slide up and down in lower support seat 11, and it all has guiding all around when moving up and down for upper support set 6 and lower support cover 9, ensure that both centers can not change.Upper support set drives oil cylinder 5 cylinder body to be contained on upper support seat 7, cylinder piston rod upward, piston rod front end and moving beam 1 are connect by flange A 2, moving beam 1 is connect by support set 6 on pull bar A 3, gland 4 and roll, support set 6 can be driven to slide up and down when upper support set drives oil cylinder 5 to stretch.Lower support seat is provided with multiple isometric locating dowel 13 for 11 times, locating dowel is provided with fixed head 15 13 times, lower support cover drives oil cylinder 14 cylinder body to be arranged on fixed head 15, cylinder piston rod upward, piston rod front end, by flange B 12 and lower support cover 9 connection, can drive lower support to overlap 9 and slide up and down when lower support cover drives oil cylinder 14 to stretch.Upper support set drives oil cylinder 5 and lower support cover to drive oil cylinder 14 to be equipped with stroke detection displacement transducer, and upper support set 6 and lower support cover 9 can accurately control along roll axial location, and therefore roll 8 axial location that works just can adjust quickly and easily automatically.
Needs roll 8 worked axial location reduce a certain amount of time, first lower support cover drives oil cylinder 14 piston rod to retract the trip, lower support cover 9 and roll 8 is driven to drop to axial location needed for operating position, then going up support set drives oil cylinder 5 piston rod to retract the trip, in drive, support set 6 drops to required axial location, and the relative position of upper support set 6 and roll 8 is constant.Needs roll 8 worked axial location promote a certain amount of time, first going up support set drives oil cylinder 5 piston rod to stretch out the trip, in drive, support set 6 rises to required axial location, then lower support cover drives oil cylinder 14 piston rod to stretch out the trip, drive lower support cover 9 and roll 8 to rise to work axial location, the relative position of upper support set 6 and roll 8 is constant.Roll 8 in working order time all have good support up and down, ensure that the rigidity of roll device.
More than be expressed as vertical roll mandrel to position adjustments method and apparatus, the method is equally applicable to horizontal roll axial location and regulates.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
