Description

A kind of interchangeable open-train mill roll chock

Technical field

The utility model belongs to bar and shape mill field more particularly to a kind of interchangeable open-train mill roll chock.

Background technique

Cross-arranging type bar and shape mill unit is equipped with using three rolls and is used, and is assisted steel rolling equipped with oscillating table before and after milling train, will be rolled Base material send supreme central roll pass to neutralize and rolls in lower central roll pass, sees that Fig. 1, Fig. 2,580 cross-arranging type three-high mill rolls use 4 Roller system (1 upper roller, 2 central rolls, 1 lower roll), use when central roll polygamy is switched for one for up-down rollers；In use process, Since top and bottom rolls bearing block form is different, up-down rollers generally require that roll disassembly workshop progress bearing block is sent to switch place when exchanging It can just be used on the machine after reason, whole process needs 3 hours or so, needs to be equipped with roll disassembly personnel, roll cleaning personnel and life Produce operator's roll change cooperation, time-consuming and laborious, influence of rolled rhythm and yield；Or it is torn open using polygamy for the reduction of a set of top and bottom rolls The problem of unloading and switch the bearing block time, bringing is that tooling prepares one times of spare parts cost promotion, and rolling cost increases.

Roll chock fit form is shown in Fig. 3-Fig. 5: rolling mill bearing, upper roll bearing seat and milling train upper cover and middle roll shaft Seat cooperation is held, bottom roll bearing block and rolling mill body cooperate, so upper roll bearing seat and the non-interchangeable use of bottom roll bearing block, pass through Roll bearing seat will be wider than bottom roll bearing block in comparison, and upper roll bearing seat is used to be cooperatively connected with upper cover equipped with two groups of lifting lugs, and Up-down rollers bearing housing internal structure is almost the same, it is ensured that and it is axial to require to use with radial and transmission speed, have improvement bearing Case general conditions.

Summary of the invention

In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a kind of interchangeable open-train mill rolls Bearing block improves the fit form of upper, middle and lower roll chock and rolling mill body, realizes that roll bearing seat is exchanged up and down, reduces roll And bearing block preparation amount, reduce personnel labor intensity.

To achieve the above object, the utility model is achieved through the following technical solutions:

A kind of interchangeable open-train mill roll chock, including suspension hook support, slide plate, upper roll bearing seat, lower roller shaft Hold seat, middle roll bearing block, the width of upper roll bearing seat and bottom roll bearing block it is of same size, middle roll bearing block two sides are equipped with vertical Column, column inside are equipped with keyway；Slide plate setting is fixedly connected in keyway, and through bolt with column；At the top of upper roll bearing seat, Bottom roll bearing block bottom has been bolted to connection suspension hook support.

The suspension hook support is an integral structure, and suspension hook support includes pedestal, lifting lug, and lifting lug is fixed on the base, and is hung Ear is equipped with lifting hole(eyelet), and pedestal is equipped with mounting hole.

At the top of the upper roll bearing seat, bottom roll bearing block bottom be equipped with the mounting groove matched with suspension hook support.

Compared with prior art, the utility model has the beneficial effects that

Interchangeable open-train mill roll chock realizes that upper and lower roll bearing block exchanges, and reduces roll and bearing block is quasi- Standby amount, reduces personnel labor intensity.Increase slide plate on the column of middle roll bearing block, optimizes upper and lower roll bearing block and middle roll shaft A fit form and precision are held, product lumber recovery and consistency are improved.Suspension hook support uses detachable structure, only in replacement bearing It is installed when seat, upper and lower roll bearing block is made to reach unanimity.It is switched and is torn open using 2/3rds up-down rollers of saving after the bearing block of this structure The transport bearing block time is unloaded, rhythm of production is promoted, improves yield；Reduce roll bearing seat spare unit deposit and roll storage level one up and down Half or more；It reduces disassembly and assembly process, personnel's amount of labour reduces more than half.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings of the specification, it should be noted that the utility model Implement embodiment not limited to the following.

See Fig. 6-Figure 14, a kind of interchangeable open-train mill roll chock, including suspension hook support 4, slide plate 5, upper roller Bearing block 1, bottom roll bearing block 3, middle roll bearing block 2, the width D of upper roll bearing seat 1 and the width W of bottom roll bearing block 3 are identical, in 2 two sides of roll bearing seat are equipped with column 7, are equipped with keyway 6 on the inside of column 7；Slide plate 5 is arranged in keyway 6, and passes through bolt and column 7 are fixedly connected；Upper 1 top of roll bearing seat, 3 bottom of bottom roll bearing block have been bolted to connection suspension hook support 4.

Wherein, suspension hook support 4 is an integral structure, and suspension hook support 4 includes pedestal 8, lifting lug 9, and lifting lug 9 is fixed on pedestal 8 On, lifting lug 9 is equipped with lifting hole(eyelet) 10, and pedestal 8 is equipped with mounting hole 11.Upper 1 top of roll bearing seat, 3 bottom of bottom roll bearing block are all provided with There is the mounting groove 12 matched with suspension hook support 4.Lower roll bearing housing increases original chamfering, prevents from doing on the inside of central roll column 7 It relates to, while increasing bottom counterface area, meet upper roller pressure spheric seating matching area.

The slide plate 5 of central roll support base column 7 and general bearing block fit clearance (- 1mm~+1mm) be it is best, can suitably put Broad gap guarantees that upper roller installation is smooth.It can improve on original bearing block and reuse completely, save fund.

The utility model can realize that upper and lower roll bearing block 3 exchanges, and reduce roll and bearing block preparation amount, reduce personnel's labor Fatigue resistance.Increase slide plate 5 on the column 7 of middle roll bearing block 2, optimizes upper and lower roll bearing block 3 and middle roll bearing block 2 cooperates shape Formula and precision improve product lumber recovery and consistency.Suspension hook support 4 uses detachable structure, only installs when replacing bearing block, Upper and lower roll bearing block 3 is set to reach unanimity.Disassembled for transport axis is switched using 2/3rds up-down rollers are saved after the bearing block of this structure It holds the time, promotes rhythm of production, improve yield；Reduce up and down 3 spare unit deposit of roll bearing seat and roll storage level more than half； It reduces disassembly and assembly process, personnel's amount of labour reduces more than half.
