Description
Technical field
It the utility model is related to a kind of composite (back-up) roll.
Background technology
Roll is the strength member on steel rolling mill's rolling mill, is rolled using pressure caused by a pair or one group of roll rolling
Steel processed, it is primarily subjected to Dynamic And Static Loads, abrasion and the influence of temperature change during rolling.Existing roll is mostly using one
Formula structure, structure is more inflexible, and its rolling width can not be adjusted, while if repair is non-when roll somewhere is damaged
It is often complicated, or even need all to scrap and throw away, renew again, maintenance cost it is higher and meanwhile use it is also more troublesome, can not
The width of roll is adjusted according to actual conditions.
Utility model content
Technical problem to be solved in the utility model is to provide one kind, and can to adjust roll at any time according to service condition wide
The composite (back-up) roll of degree.
Technical scheme is used by the utility model：A kind of composite (back-up) roll, it includes roll shaft, is arranged on roll shaft
Fixed connecting plate, the initial disk for being arranged on fixed connecting plate side, the extension disc and use for being arranged on initial disk side
In fixed initial disk and the fixing axle of extension disc, shoulder hole is evenly arranged with the fixed connecting plate, described first
The through hole corresponding with the shoulder hole, the initial disk and the profile for extending disc are provided with beginning disc and extension disc
Size is corresponding；Described fixing axle one end is arranged in shoulder hole, and the other end passes through initial disk and the through hole extended on disc
Stretch out and extend outside disc, at least provided with two pin-and-holes, the pin-and-hole and the initial disk and extension in the fixing axle
The lateral surface of disc is corresponding, and initial disk and extension disc are fixed on fixed connecting plate after latch insertion pin-and-hole.
Fixed in the roll shaft and initial disk and extension disc by key connection.
Arc positioning groove is provided with the fixed connecting plate, is provided with the initial disk and determines with the arc
The corresponding locating dowel of position groove location, is provided with connecting plate, in the arc positioning groove in the side of the arc positioning groove
The other end is be hinged to be provided with fixation spring tab, and the other end of fixation spring tab is fixedly connected by bolt with connecting plate, in the fixation
The block rubber for being contacted with locating dowel is provided with the inside of shell fragment.
Good effect of the present utility model is：The utility model can be realized by adjusting the installation number of extension disc
Different rolling widths, use range can be more extensively adjusted at any time according to service condition, while if some disc damages
Bad when, it can directly pull down and be changed, without carrying out cumbersome repair, save maintenance cost.The position of pin-and-hole with
Extend the corresponding setting of lateral surface of disc, after extension disc is installed in initial disk, steady pin be inserted into pin-and-hole,
Initial disk can be realized with extending being brought into close contact for disc.Initial disk uses single key connection and roller with extending disc
Axle is attached, and the service life of connecting key and keyway is effectively ensured.There is arc positioning groove on fixed connecting plate simultaneously, first
The locating dowel being inserted into arc positioning groove is provided with beginning disc, then fixation spring tab and connecting plate are connected, it is fixed
Block rubber in shell fragment compresses locating dowel, can effectively eliminate the trueness error of initial disk key connection, ensure initial disk with
Roll shaft synchronous axial system.
Brief description of the drawings

Fig. 2 is that the utility model is fixedly connected with plate structure schematic diagram；
Fig. 3 is the utility model pin-and-hole structure schematic diagram.
Embodiment
As shown in Figure 1, the utility model includes roll shaft 1, the fixed connecting plate 2 being arranged on roll shaft 1, is arranged on fixation
The initial disk 5 of the side of connecting plate 2, the extension disc 6 for being arranged on the side of initial disk 5 and for fixing the and of initial disk 5
Extend the fixing axle 4 of disc 6, shoulder hole 3 is evenly arranged with the fixed connecting plate 2, in the initial disk 5 and extend
The through hole corresponding with the shoulder hole 3 is provided with disc 6, the initial disk 5 is relative with the appearance and size for extending disc 6
Should；Described one end of fixing axle 4 is arranged in shoulder hole 3, and the other end stretches out through initial disk 5 and the through hole extended on disc 6
Extend outside disc 6, at least provided with two pin-and-holes 8, the pin-and-hole 8 and the initial disk 5 and extension in the fixing axle 4
The lateral surface of disc 6 is corresponding, and initial disk 5 and extension disc 6 are fixed on fixed connecting plate 2 after latch insertion pin-and-hole 8.
The roll shaft 1 is fixed with initial disk 5 and extension disc 6 by key connection, connecting key 9 is set on roll shaft 1, in initial disk
5 and extend disc 6 on be provided with keyway 10, the spacing of connecting key 9 is identical with the width of the initial disk 5, with ensure often
One disc is all connected by independent key connection with roll shaft 1.As shown in Figure 3, it is provided with wedge in the pin-and-hole 8
16, after latch inserts pin-and-hole 8, inwardly extruding extends disc 6 in the presence of wedge 16, makes extension disc 6 and initial disk 5
It is in close contact.
As shown in Figure 2, arc positioning groove 11 is provided with the fixed connecting plate 2, is set in the initial disk 5
The locating dowel 12 corresponding with the position of arc positioning groove 11 is equipped with, the side of the arc positioning groove 11 is provided with connection
Plate 14, it is hinged in the other end of the arc positioning groove 11 and is provided with fixation spring tab 13, the other end of fixation spring tab 13 passes through spiral shell
Bolt is fixedly connected with connecting plate 14, and the inner side of the fixation spring tab 13 is provided with the block rubber for being contacted with locating dowel 12.
Because key connection can have foozle, after installing, there may be the problem of loosening between disc and roll shaft 1, so
A fixed structure is further added by, after initial disk 5 is connected with fixed connecting plate 2, locating dowel 12 can be inserted into arc positioning groove 11
It is interior, then extruded by the block rubber in fixation spring tab 13 fixing 12, such key connection, along with fixation spring tab 13
Extruding, positioning completely is realized to initial shell fragment, effectively prevents from loosening between initial disk 5 and roll shaft 1.
In this application, it is inner side close to the side of fixed connecting plate 2, the side away from fixed connecting plate 2 is outside.
