Description
Technical field
The invention belongs to metallurgy industry rolling system technical field, disappear more specifically to a kind of short stress path rolling mill
Except thread pitch bascule.
Background technology
Usually require to use milling train in System on Rolling Steel, wherein, short stress path rolling mill is because with rigidity height, changing quickly
It is widely used Deng many merits on the long material production line of hot rolling, countries in the world are also emerged much on short-stress path
The invention of milling train.Short stress path rolling mill movement is general mainly to be filled by roll gap adjustment device, pull bar assembling, roll assembling and guide beam
Formed with four parts.
Wherein, pull bar assembling is linked as bearing block, screwdown gear, sealing, support, bascule etc. with four tension force pull bars
One, form radial direction main body.Mainly upper and lower roll gap is adjusted by thread transmission for pull bar, and its concrete structure is：Draw
Bar surface is provided with external screw thread, and pull bar outer cover is provided with sleeve, and the bearing block for back-up roll is fixedly installed on sleeve, and
And the internal thread being adapted to the external screw thread on pull bar is provided with sleeve.When needing to carry out roll gap adjustment, driven by drive device
Dynamic pull bar rotates, and pull bar constitutes typical screw slider mechanism with sleeve, and the rotation of pull bar translates into sleeve in pull rod shaft
Upward upper and lower translation motion, and then drive bearing block to move up and down, it is achieved thereby that the regulation of roll gap size.
But because thread transmission can all have a certain size gap, and the presence in this gap can influence entirely to roll
The precision of machine and use, therefore, usually require to design corresponding gap eliminator in pull bar assembling in the prior art, and put down
Weighing apparatus device is mechanism particularly important in milling train pull bar radial clearance cancellation element, existing bascule mainly by disc spring group and
Guide rod etc. forms.
Such as, Chinese patent 201510958247.9 discloses a kind of milling train and its pretension balance system, this application case it is pre-
Tight balance system, including：Roll both ends are arranged on, and carry externally threaded pull bar；Be threaded on pull bar, and with pull bar structure
Into the inner layer sleeve of screw slider mechanism；It is connected on bearing block, and is set in the outer layer sleeve on pull bar, the outer layer sleeve
Bottom offseted by sleeve gasket and the inner layer sleeve, and one end that the sleeve gasket is in contact with the inner layer sleeve is sphere；
It is threaded on the pull bar, and the balance nut of screw slider mechanism is formed with the pull bar；It is set on the pull bar,
And the balance nut is located at transparent cover by the transparent cover that lower end is connected with the outer layer sleeve and the bearing block, the transparent cover
It is internal；Both ends offset with the transparent cover and the balance nut respectively, and the preloading spring in compressive state.
And for example, Chinese patent 201510299383.1 discloses a kind of bar reducing sizing mill, and this application case is adjusted including roll gap
Regulating device, pull bar assembling, frame, beam, roll assembling, guide beam, wherein, roll assembling include topping roll assemble, under roll
Roller assembles, and the pull bar assembling includes pull bar, is arranged on the butterfly for eliminating gap between pull bar and copper nut of pull bar upper/lower terminal
Shape spring damper.The butterfly spring shock absorber strap is set around pull bar, and it includes shim pack, disc spring, pressure ring, gasket ring, disc spring
Guide rod is extruded, so as to eliminate the gap between pull bar and copper nut.
But because the steadiness of existing milling train gap eliminator is relatively poor, and easy discontinuity, so as to cause
It eliminates the effect in gap and is affected, and then influences the rolling accuracy of milling train, meanwhile, dress is eliminated using the gap of existing milling train
To put, disc spring is also easy to produce fatigue failure afterwards by long-term use, and its service life is relatively short, and because every group of disc spring group is generally by more
Piece disc spring superposition composition, existing mechanism install and changed in actual use very troublesome.
