Abstract
The invention provides a technical scheme of an anti-jamming mechanism for side roller lifting of a straightening machine. According to the scheme, the mechanism comprises a supporting roller bearing seat and a pressure bearing head used for being connected with a lifting mechanism of the straightening machine, and the pressure bearing head is located under the supporting roller bearing seat. The mechanism is characterized in that the supporting roller bearing seat is fixedly connected with the pressure bearing head, and the lower surface of the supporting roller bearing seat is closely attached to the upper surface of the pressure bearing head. By using the mechanism, the phenomenon that the lifting of a side roller is jammed on account of the falling of oxide scales is effectively avoided, and the problem that the side roller, a supporting roller and the lifting mechanism are not lifted or dropped synchronously is solved.
Description
Technical field
What the present invention relates to is a kind of flattener edge roll lifting Anti-blocking mechanism.
Background technology
The limit roller of existing straightener generally has elevating function, concrete is, the lifting of backing roll is adjusted by elevating mechanism, backing roll drives the lifting of limit roller, thus the height of adjustment limit roller, to control the leveling effect of steel plate, therefore, the quality that limit roller height regulates directly has influence on the straightening capacity of straightener.
In existing straightener, connected mode between back-up chock with elevating mechanism generally adopts draw-in groove to be connected, in straightening steel plate process, iron scale on steel plate easily comes off, along with the prolongation of service time, iron scale can gather in the both sides of back-up chock, frictional force when causing backing roll to be elevated and between framework and adjacent shaft bearing strengthens and cannot normally be elevated, also the lifting of limit roller can not just normally be driven, sometimes, also can produce the problem of the asynchronous lifting in two ends of same backing roll, cause backing roll one-way support limit roller, make to produce violent wearing and tearing between backing roll and limit roller, steel plate is made to produce impression, the phenomenon of the damage of the backing roll body of roll or fracture.
Backing roll or limit roller damage and directly will affect steel plates straightening, must change in time, but a whole set of roller system must be changed when changing, and consuming time, effort, upsets the normal production order, bring larger economic loss.
Existing flattener edge roller mechanism never solves the problem of limit roller backing roll lifting asynchronous with elevating mechanism, becomes a great problem of restriction straightener performance.
Summary of the invention
Technical problem to be solved by this invention, be exactly for the deficiency existing for prior art, and provide a kind of flattener edge roll to be elevated the technical scheme of Anti-blocking mechanism, the jam phenomenon that the lifting using the present invention effectively to avoid the opposite side roller that comes off of iron scale produces, solves the problem of the asynchronous lifting of limit roller, backing roll and elevating mechanism.
This programme is achieved by the following technical measures: a kind of flattener edge roll lifting Anti-blocking mechanism, comprise back-up chock and the pressure bearing head for being connected straightener elevating mechanism, described pressure bearing head immediately below back-up chock described back-up chock with between pressure bearing head for being fixedly connected with, the lower surface of described back-up chock and the upper surface of pressure bearing head fit tightly.
Further improvement of the present invention also has, described back-up chock is provided with connecting hole I, described pressure bearing head is provided with described connecting hole I with the use of connecting hole II, coupling assembling is provided with in described connecting hole I and connecting hole II, by coupling assembling, back-up chock is fixedly connected with pressure bearing head, the pulling force that the pressure bearing head be connected with elevating mechanism produces in decline process is all transferred on back-up chock, even if some iron oxide jam, under powerful elevating mechanism pulling force, also can realize normally and the lifting of relative synchronization.
Further improvement of the present invention also has, and described connecting hole I and connecting hole II are bolt hole, and described coupling assembling is bolt assembly.
Further improvement of the present invention also has, described bolt assembly comprises screw rod, nut and is fixed on the pressing plate of screw rod lower end, during use, to the screw rod of pressing plate be fixed with from bottom to top successively through connecting hole II and connecting hole I, and in the upper end of screw rod by nut screwing clamping, to ensure that pressing plate, pressure bearing head and back-up chock three fit tightly, thus achieve being fixedly connected with of back-up chock and pressure bearing head.
Further improvement of the present invention also has, and is provided with pad between described nut and the upper surface of back-up chock.
Further improvement of the present invention also has, and the lower surface of described back-up chock is plane.
Further improvement of the present invention also has, and the upper surface of described pressure bearing head is plane.
Further improvement of the present invention also has, and described coupling assembling has two groups at least.
The beneficial effect of this programme can be learnt according to describing of such scheme, owing to comprising back-up chock and the pressure bearing head for being connected straightener elevating mechanism in this scenario, described pressure bearing head is positioned at immediately below back-up chock, described back-up chock with between pressure bearing head for being fixedly connected with, the lower surface of described back-up chock and the upper surface of pressure bearing head fit tightly.The present invention effectively solves the problem of the asynchronous lifting of limit roller, backing roll and elevating mechanism, avoid because of limit roller, the asynchronous limit roller of lifting generation of backing roll, the damage of backing roll, simultaneously, structure of the present invention is simple, easy to process, can be used for the transformation to existing straightener, also can be used for the processing and manufacturing of the straightener of new production.
As can be seen here, compared with prior art, have outstanding substantive distinguishing features and significant progress, its beneficial effect implemented also is apparent in the present invention.
