Abstract
The utility model discloses a hard alloy composite roller which comprises a roller core and a hard alloy composite roller ring. A high strength bonding layer is arranged between the roller core and the roller ring; the roll core is provided with a projecting portion of which the diameter is less than or equal to the external diameter of the hard alloy composite roller ring; a bonding layer is arranged at least between one side of the projecting portion and one end face of the hard alloy composite roller ring. The composite roller has the advantages of simple structure, convenient installation and dismantlement, low manufacturing cost, and high bonding strength between the roller ring and the roller core. The utility model can be applied to the rolling situations with big roll force and higher requirement for anti-torsional shearing force.
Description
Technical field
The utility model relates to the roll that metallurgy industry steel rolling is used, and particularly makes the bonding composite roller of collars with carbide alloy.
Background technology
Roll is an important instrument during steel rolling is produced.For satisfying the instructions for use that steel rolling is produced, the general composite structure that adopts, adopt promptly that wearability is good, intensity is high and the carbide alloy of good heat resistance is made collars, make the composite structure of roller core with materials such as the spheroidal graphite cast-iron that can bear higher draught pressure, moment of torsion and curved power or invar alloy, structural alloy steels.External general the employing is cast into composite algorithm (CIC method), and perhaps high temperature insostatic pressing (HIP) (HIP) composite algorithm is produced the carbide alloy composite roll, but complex process, the cost height.The bonding combined type of the general employing of domestic present carbide alloy composite roll promptly is provided with tack coat between axle core and collars, roller core and carbide roll ring close adhesion are integral.This technical pattern is simple, cost is low, and roller core is reusable.The bonding face of roller core and collars is only limited to the outer surface of roller core and the inner surface of collars, so the adhesion strength of roller core and collars is big inadequately, and such composite roll can only be used for the rolling occasion that roll-force is little, the requirement of torque resistant shearing force is lower.Although the composite roll that has has axial non-slip groove on the faying face of roller core and carbide roll ring, to strengthen its adhesive strength, improved difficulty of processing and manufacturing cost, effect is also not obvious.
The utility model content
It is simple that the purpose of this utility model provides a kind of manufacturing process, the carbide alloy composite roll that collars and roller core adhesive strength are high.
The utility model adopts a kind of like this technical scheme to realize: composite roll of the present utility model comprises roller core and carbide roll ring, be provided with the high strength bonding layer between roller core and the collars, projection is arranged on roller core, the diameter of this projection is less than or equal to the external diameter of carbide roll ring, between an end face of the one side of this projection and carbide roll ring adhesive linkage is arranged at least.
Because collars and roller core are not only bonding in the axial direction, and an end face of end face of collars and roller core projection is bonding at least, thereby increased the bond area of collars and roller core, strengthened the two adhesion strength, and improved the distribution of composite roll collars and mutual power of roller core in rolling process, made composite roll of the present utility model can be applicable to the rolling occasion that roll-force is big, the torque resistant shearing force is had relatively high expectations.Again because the utility model is simple in structure, so also have beneficial effects such as easy installation and removal, low cost of manufacture.
As further improvement of the utility model, on a bonding plane of the collars of composite roll and roller core projection, radially have groove at least.Like this, can further strengthen bond area, improve the adhesive strength of collars and roller core.
Description of drawings
Fig. 1 is the longitudinal section of composite roll of the present utility model.Among the figure: 1. the projection on high strength bonding layer 5. roller core of adhesive linkage 3. carbide roll rings, 4. roller cores of roller core 2. roller core projections and carbide roll ring end face and carbide roll ring inner surface
Fig. 2 is the cutaway view along Figure 1A-A direction.Among the figure: 6. the groove on the roller core projection end face
The specific embodiment
Carbide alloy composite roll shown in Figure 1 comprises roller core 1 and carbide roll ring 3, be provided with high strength bonding layer 4 between roller core 1 and carbide roll ring 3 inner surfaces, projection 5 is arranged on roller core 1, the diameter of this projection 5 is less than or equal to the external diameter of carbide roll ring 3, and the end face of the end face of carbide roll ring 3 and roller core projection 5 has adhesive linkage 2.
Fig. 2 is the cutaway view of the carbide alloy composite roll of the another kind of embodiment of the utility model along Figure 1A-A direction.Have groove 6 on the projection of roller core shown in the figure 5 end faces, on the end face of the collars 3 that bonds with it, also can have groove,, improve the adhesive strength of collars 3 and roller core 1 to increase bond area.
Hard alloy roll of the present utility model can be provided with a plurality of projections according to needs of production on a roller core, and can bonding a plurality of carbide roll rings.Roller core also can be selected steel alloy and other qualified material for use according to actual conditions.
