Matter alloy 1 external diameter of collars is almost big, in order to lock carbide roll ring, a clamp nut on the other end of roll shaft first covers
4, clamp nut 4 is provided with piston 6 and locking nut 3, by opening oil filler point 8 on clamp nut, promotes piston to shaft shoulder direction
It is mobile, enough pretightning forces are then being provided by locking nut screwing, but have screw thread for clamp nut, its inner ring, its
Also there is screw thread outer ring, causes the wall thickness of clamp nut relatively thin, it is impossible to bears sufficiently high pressure, the pretightning force for causing it to provide
It is limited.
The content of the invention
It is an object of the invention to provide a kind of hard alloy composite roll, can effectively solve the problem that existing hard alloy composite roll
Pretightning force it is limited the problem of.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：A kind of hard alloy is compound
Roller, including roll shaft, carbide roll ring, locking nut and clamp nut, the carbide roll ring is set on roll shaft, described
One end of roll shaft is provided with the shaft shoulder, and the diameter of the shaft shoulder is less than the external diameter of carbide roll ring, set between carbide roll ring and the shaft shoulder
There is piston, oiling chamber is formed between piston and the shaft shoulder end face, oil filler point in the axial direction is provided with the shaft shoulder, it is described
Oil filler point is communicated with oiling chamber, and the locking nut is additionally provided with the perisporium of the shaft shoulder, and the clamp nut is arranged on roll shaft
The other end.
Preferably, the piston includes minor diameter part and large-diameter portion, and the external diameter of the minor diameter part and large-diameter portion is equal, described small
The inner peripheral surface in footpath portion coordinates with the sealing of roll peripheral face, and the outer circumference surface sealing of the inner peripheral surface and the shaft shoulder of the large-diameter portion is matched somebody with somebody
Close；The end face of minor diameter part, the inner peripheral surface of large-diameter portion, the shaft shoulder surround oiling towards the end face of minor diameter part and roll shaft outer circle wall
Chamber, it is easy to the movement of piston after oiling.
Preferably, the inner peripheral surface of the minor diameter part is provided with first annular seal groove circumferentially, described first annular
Sealing ring is provided with seal groove；Ensure the sealing of minor diameter part and roll shaft.
Preferably, the second axially disposed annular seal groove, second ring are provided with the outer circumference surface of the shaft shoulder
Sealing ring is provided with shape seal groove；Improve the sealing between large-diameter portion and the shaft shoulder.
Compared with prior art, it is an advantage of the invention that：Clamp nut and locking nut, piston are separately positioned on roll shaft
Both ends, and oil filler point is opened on the shaft shoulder, and because the shaft shoulder and roll shaft are integrally manufactured, and the shaft shoulder only has outer circle wall needs
The screw thread coordinated with locking nut is set, so oil filler point is opened up on clamp nut relative to tradition, its pressure that can be born
Power improve, also implying that the pretightning force of offer will greatly improve, ensure carbide roll ring using when validity obtain greatly
Width is lifted.
Brief description of the drawings
Fig. 1 is a kind of existing structural representation of hard alloy composite roll；
Fig. 2 is a kind of structural representation of hard alloy composite roll of the present invention；
Fig. 3 is the structural representation that piston, locking nut and the shaft shoulder coordinate in the present invention.
Embodiment
It is a kind of embodiment of hard alloy composite roll of the present invention refering to Fig. 2, Fig. 3, a kind of hard alloy composite roll, including
Roll shaft 1, carbide roll ring 2, locking nut 3 and clamp nut 4, the carbide roll ring 2 is set on roll shaft 1, described
One end of roll shaft 1 is provided with the shaft shoulder 5, and the diameter of the shaft shoulder 5 is less than the external diameter of carbide roll ring 2, carbide roll ring 2 and the shaft shoulder 5
Between be provided with piston 6, oiling chamber 7 is formed between piston 6 and the shaft shoulder 5 end face, is provided with the axial direction on the shaft shoulder 5
Oil filler point 8, the oil filler point 8 are communicated with oiling chamber 7, and the locking nut 3 is additionally provided with the perisporium of the shaft shoulder 5, described tight
Gu nut 4 is arranged on the other end of roll shaft 1.Clamp nut 4 and locking nut 3, piston are separately positioned on to the both ends of roll shaft 1,
And oil filler point 8 is opened on the shaft shoulder 5, because the shaft shoulder 5 and roll shaft 1 are integrally manufactured, and the shaft shoulder 5 only has outer circle wall to need to set
The screw thread coordinated with locking nut 3 is put, so oil filler point 8 is opened up on clamp nut 4 relative to tradition, its pressure that can be born
Power improves, and also implying that the pretightning force of offer will greatly improve, and ensures that validity when carbide roll ring 2 uses obtains greatly
Width is lifted.
In order to preferably form oiling chamber 7, the piston 6 includes minor diameter part 9 and large-diameter portion 10, the minor diameter part 9 and big
The external diameter in footpath portion 10 is equal, and the inner peripheral surface of the minor diameter part 9 coordinates with the sealing of the periphery of roll shaft 1, the large-diameter portion 10 it is interior
The outer circumference surface sealing of periphery and the shaft shoulder 5 coordinates, thus by the end face of minor diameter part 9, the inner peripheral surface of large-diameter portion 10, the shaft shoulder
5 surround oiling chamber 7 towards the end face of minor diameter part 9 and the outer circle wall of roll shaft 1, are easy to the movement of piston after oiling.
The sealing of piston and roll shaft 1 and the shaft shoulder 5 is further improved, the inner peripheral surface of the minor diameter part 9 was provided with along week
To first annular seal groove 11, is provided with sealing ring in the first annular seal groove 11, is opened on the outer circumference surface of the shaft shoulder 5
There is the second axially disposed annular seal groove 12, sealing ring is provided with second annular seal groove 12.Certain second annular
Seal groove 12 can also be opened on the inner peripheral wall of large-diameter portion 10.
In use, piston first is inserted in into roll shaft 1, carbide roll ring 2 and spacer ring are being inserted in successively, is finally screwing on fastening spiral shell
Mother 4, then opens up injection hydraulic oil by the oil filler point 8 on the shaft shoulder 5, piston is pushed away toward the direction of clamp nut 4, enough when getting to
After pressure, the position of piston is fixed by locking nut 3, sealed oil-filling hole 8, ensures that collars there are enough pretightning forces.
The specific embodiment of the present invention is the foregoing is only, but the technical characteristic of the present invention is not limited thereto, Ren Heben
The technical staff in field in the field of the invention, all cover among the scope of the claims of the present invention by the change or modification made.
