Description
Technical field
The utility model relates to steel rolling equipment, is exactly specifically rolling-mill housing.
Background technology
Mostly the processing of wire and rod in prior art, be to adopt mill milling.And milling train point generally can be divided into memorial archway open frame, cantilevered frame with regard to its structure or be welded as memorial archway open frame by section bar, upper and lower roll forms roller system and implements rolling to material to be rolled.
In order to stationary roll assembly, rolling-mill housing finally needs to be shaped to a constitutionally stable fixed frame.
At present, in the milling train of no matter memorial archway open frame, cantilevered frame, example is installed as so that memorial archway open frame is vertical, the distortion of its above-below direction is comparatively large, be difficult to control, because step is all adopt bolt base part to be fixed on the bottom support bracket of memorial archway open frame, the screwdown gear of top chock is normally arranged in upper beam, during such rolling, the all elongation strains by pulling force in its whole length range of the column of memorial archway open frame between bottom support bracket and upper beam, its anamorphic stretching amount is large; For cantilevered frame, the deformation of its column is substantially similar.In other words, the insufficient rigidity of rolling-mill housing, the in addition distortion of other parts, the error after accumulative is just very large, is difficult to meet the requirement of rolling season.Especially the frame of complete machine casting, processing no doubt facilitates, but the defect overcome due to the limitation and being difficult to of the mechanical property of foundry goods, high-precision rolling mill then always wishes to avoid adopting casting structure.
Name is called the patent document of " the backing roll body of roll is with the sheet rolling mill of hydraulic pressure hold-down devices " (publication number CN101658862A), its rolling-mill housing comprises superposed horizontal frame 10, is positioned at the frame underbeam 12-1 of bottom and is positioned at column 1 between the two, its overall structure can regard memorial archway open frame as, and column wherein operationally all elongation strain can occur within the scope of its overall length.
Name is called the patent document of " composite machine frame of mill " (publication number CN2796875Y), its frame comprises, sill 1, 4 and connect both each column 2, on, sill 1, 4 and column 2 between adopt bar 8 to be connected with nut 9, such column 2 is just subject to the effect of compression, the defect of this structure is, on, sill 1, cannot meet the demands perpendicular to the location on column 2 direction between 4 and column 2, because, on, sill 1, the pressure provided each other between 4 and column 2, maintain and will depend on frictional force each other perpendicular to the position in column 2 direction, this is extremely insecure, in addition, due to structure self restriction that bar 8 is connected with nut 9, its pretightning force provided is very limited, external force in the operation of rolling is once counteract the pretightning force that bar 8 and nut 9 provide, may cause time serious departing from each other, with the rolling accuracy that is far from being between upper and lower crossbeam 1,4 and column 2.
Upright column of rolling mill of the prior art is independently rod member shape, and most of structure is the stress by pulling force.The applicant with regard to application number technical scheme disclosed in the patent of invention of 201110129249.9, describes column by the effect of pre-tensile stress on October 31st, 2012, to ensure the deformability of frame, guarantee roll fix after roll gap precision.
Summary of the invention
The purpose of this utility model is to provide a kind of rolling-mill housing, improves the non-deformability of framework pillar.
For achieving the above object, the utility model have employed following technical scheme: a kind of rolling-mill housing, comprise bottom support and crossbeam, column between bottom support and crossbeam comprises draw-in bar and is set in the tubing string of draw-in bar outside, draw-in bar one end is fixedly connected with bottom support, the other end of draw-in bar is connected with nut through the rod end after crossbeam, and the two ends of tubing string are resisted against on bottom support and crossbeam respectively.
In technique scheme, column is made up of draw-in bar and the tubing string being set in draw-in bar outside, after assembling, the effect of draw-in bar tension power, the tubing string effect of being stressed, pulling force and pressure cancel each other out as internal force at machine frame inside, and draw-in bar and tubing string two parts produce corresponding distortion by prestressing force effect, producing active force by parts to be rolled because of distortion in the operation of rolling is delivered on column through roll, its size of this external force is generally all less than the prestressing force that column has been subjected under normal circumstances, so both can maintaining roller gap or claim roller spacing to keep stable, guarantee the realization of rolling accuracy.
