Abstract
The utility model relates to a combined assembly roller. The combined assembly roller comprises a roller shaft and a roller sleeve, the surface of the position, on the outer side of the roller sleeve, of the roller shaft is connected with a locking nut, positioning bolts are evenly distributed on the outer surface of the locking nut, the positioning bolts enable the locking nut and the roller shaft to be connected into a whole, and a fastening key is arranged at the joint of the inner side of the roller sleeve and the roller shaft; the roller sleeve comprises a steel substrate and a hard alloy ring connected to the outer surface of the steel substrate, the hard alloy ring and the steel substrate are cast in a whole structure, and a connection layer is arranged between the hard alloy ring and the steel substrate; the inner surface of the roller sleeve is in a sawtooth shape, and the outer surface, matched with the roller sleeve, of the roller shaft is in a sawtooth shape. The combined assembly roller has the advantages that the structure is simple, reasonable axial stress is obtained, and work stability is high; hard alloy is only used for the portion in need of the hard alloy, and therefore cost is relatively low; the sawtooth-shaped structure is used for connection, larger torque can be transmitted, and the using requirement for different machine frame working conditions is met.
Description
Technical field
The utility model relates to a kind of combination assembling roll.
Background technology
Roll is the strength member on steel rolling mill's rolling mill, and the pressure producing while utilizing a pair of or one group of roll rolling rolls stone roller steel, Dynamic And Static Loads when it mainly bears rolling, the impact of wearing and tearing and variations in temperature.The user demand of producing for meeting steel rolling, the body of roll requires to have the good quality work layer of high wear-resistant, anti-strip, anti-surface coarsening.Existing roll adopts integral structure mostly, and structure is more inflexible, and material is single, and manufacturing cost is high, repairs more loaded down with trivial details.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of combination assembling roll.
The utility model solves the technical scheme that its technical problem adopts: a kind of combination assembling roll, comprise roll shaft and roller shell, the roll shaft surface in roller shell outside is connected with locking nut, the uniform bolt of locking nut outer surface, bolt is connected as a single entity locking nut and roll shaft, and roller shell inner side is provided with fastening key with the junction of roll shaft; Roller shell comprises steel matrix and the carbide ring that is connected in steel matrix outer surface, and carbide ring and steel matrix are cast into overall structure, between carbide ring and steel matrix, are provided with articulamentum; The inner surface indentation of roller shell, the roll shaft outer surface indentation coordinating with roller shell.
Further, bolt is M14, and quantity is 3.
The beneficial effects of the utility model are: simple in structure, there is rational axial prestress, and job stability is high; Carbide alloy is only used in the position that must use, and cost is lower; Be connected to laciniation, can transmit more high pulling torque, meet the user demand of different frame operating modes.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in Fig. 1 A-A to cutaway view.
Wherein: 1. roll shaft, 2. locking nut, 3. bolt, 4. fastening key, 5. steel matrix, 6. carbide ring.
The specific embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of combination assembling roll as shown in Figure 1 and Figure 2, comprise roll shaft 1 and roller shell, roll shaft 1 surface in roller shell outside is connected with locking nut 2, the uniform bolt 3 of locking nut 2 outer surface, bolt 3 is connected as a single entity locking nut 2 and roll shaft 1, and roller shell inner side is provided with fastening key 4 with the junction of roll shaft 1; Roller shell comprises steel matrix 5 and the carbide ring 6 that is connected in steel matrix 5 outer surfaces, and carbide ring 6 is cast into overall structure with steel matrix 5, between carbide ring 6 and steel matrix 5, is provided with articulamentum.
The inner surface indentation of roller shell, the roll shaft 1 outer surface indentation coordinating with roller shell.Be connected to laciniation, can transmit more high pulling torque, meet the user demand of different frame operating modes.
During rolling, carbide ring 6 provides the wearability of pass excellence, and steel matrix 5 is transmitted roll torque by keyway and the locking device of side, and strength and toughness is provided.Carbide alloy involves great expense, and in composite hard alloy roller shell, wear-resisting carbide alloy is a part for whole roller shell, be only used in the position that must use, so cost is lower.
On the roll mandrel that roller shell hot charging need be made at forged steel pieces during assembling, by fastening key 4 and roll shaft, be connected as a single entity.Install afterwards and screw locking nut 2, eliminate the gap of collars side and roll shaft side.Locking nut 2 will again be tightened in roller shell cooling procedure.Locking nut front is evenly equipped with M14 positioning spiro pit, after roller shell is thoroughly cooling, according to the position of positioning spiro pit, joins and bore 3 locating holes on the body of roll, finally installs bolt 3 additional and is locked, and roll shaft 1 and locking nut 2 are connected as a single entity.During rolling, the powerful frictional force and the fastening key 4 that mainly by hot charging, produce transmit roll torque, and 2 of locking nuts play locking effect.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
