Abstract
The invention discloses a kind of hard alloy composite roll with pretightning force, including mandrel, spacer ring and collars, one end of the mandrel is provided with step, the collars and spacer ring are alternately set on mandrel, the other end of the mandrel is provided with locking nut and is used to spacer ring and collars being locked at mandrel, the spacer ring is provided with elastic preload piece towards having circumferentially disposed annular groove on the face of collars in the annular groove, the depth of the height of the elastic preload piece more than annular groove.It is an advantage of the invention that：By opening up annular groove on spacer ring, and elastic preload piece is set in annular groove, after locking nut screwing, produce certain pretightning force, locking nut is kept not release in use, and elastic preload piece can form barrier, prevent aqueous vapor from entering between spacer ring and collars, make spacer ring be not easy to get rusty, keep that between spacer ring and collars gap will not be produced.
Description
Technical field
The present invention relates to a kind of hard alloy composite roll with pretightning force.
Background technology
Hard alloy composite roll is mainly used on high-speed wire finish-rolling and pre-finishing mill, mainly wears carbide roll ring
On mandrel, spacer ring is provided between carbide roll ring, the end of mandrel is locked by bolt again, and existing this structure makes
After a period of time, bolt can release, and cause hard alloy composite roll to fail.
The content of the invention
It is an object of the invention to provide a kind of hard alloy composite roll with pretightning force, existing hard can effectively solve the problem that
The locking of alloy composite roll easily releases, the problem of causing composite roll to fail.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：It is a kind of with the hard of pretightning force
Matter alloy composite roll, including mandrel, spacer ring and collars, one end of the mandrel are provided with step, and the collars and spacer ring alternately cover
It is located on mandrel, the other end of the mandrel is provided with locking nut and is used to spacer ring and collars being locked at mandrel, the spacer ring
There is circumferentially disposed annular groove on towards the face of collars, elastic preload piece is provided with the annular groove, the elasticity is pre-
The height of tight part is more than the depth of annular groove.
The spacer ring is spaced towards at least two ring annular grooves are radially provided with the face of collars between adjacent annular groove
1cm~3cm.
The rib disconnected at least one is provided with per ring annular groove.
Rib on different annular grooves is radially staggered distribution.
The step is respectively provided with circumferentially disposed annular recessed towards the end face of collars and locking nut towards the end face of collars
Groove, elastic preload piece is also provided with annular groove.
Compared with prior art, it is an advantage of the invention that：By opening up annular groove on spacer ring, and in annular groove
It is interior that elastic preload piece is set, after locking nut screwing, certain pretightning force is produced, keeps locking nut not in use
Release, and elastic preload piece can form barrier, prevent aqueous vapor from entering between spacer ring and collars, make spacer ring be not easy to get rusty, and protect
Gap will not be produced by holding between spacer ring and collars.
Preferably, the spacer ring is towards being radially provided with least two ring annular grooves, adjacent annular groove on the face of collars
Between be spaced 1cm~3cm；Set at least two ring annular grooves to may further ensure that pretightning force has message, while keep good
Sealing, and be smaller than that 1cm can make that annular groove leans between adjacent annular groove it is too near, it is swollen in elastic preload piece stress
After swollen easily be close together generation interference, spacing be more than 3cm make two annular grooves between spacing it is excessive, air heats therein
Expansion easily washes elastic preload piece open.
Preferably, the rib disconnected at least one is provided with per ring annular groove, spacer ring is kept by rib as far as possible
Intensity.
Preferably, the rib on different annular grooves is radially staggered distribution, the stress disperseed on axial direction.
Preferably, the step is respectively provided with circumferentially disposed towards the end face of collars and locking nut towards the end face of collars
Annular groove, elastic preload piece is also provided with annular groove；Further strengthened by step end face and locking nut end face pre-
Clamp force.
Brief description of the drawings
Fig. 1 is the sectional view of the present invention；
Fig. 2 is the front view of mandrel in the present invention.
Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings.Below with reference to
The embodiment of accompanying drawing description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
In the description of the invention, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width ",
The instruction such as " thickness ", " on ", " under ", "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer "
Orientation or position relationship are based on orientation shown in the drawings or position relationship, are for only for ease of the description present invention and simplification is retouched
State, rather than instruction or imply signified device or element there must be specific orientation, with specific azimuth configuration and operation,
Therefore it is not considered as limiting the invention.
In addition, term " first ", " second " are only used for describing purpose, and it is not intended that instruction or hint relative importance
Or the implicit quantity for indicating indicated technical characteristic.Thus, define " first ", the feature of " second " can be expressed or
Implicitly include at least one this feature.In the description of the invention, " multiple " are meant that at least two, such as two, three
It is individual etc., unless otherwise specifically defined.
In the present invention, unless otherwise clearly defined and limited, term " installation ", " connected ", " connection ", " fixation " etc.
Term should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integrally；Can be that machinery connects
Connect or electrically connect or can communicate each other；Can be joined directly together, can also be indirectly connected by intermediary, can be with
It is connection or the interaction relationship of two elements of two element internals, is limited unless otherwise clear and definite.For this area
For those of ordinary skill, the concrete meaning of above-mentioned term in the present invention can be understood as the case may be.
It is a kind of embodiment of the hard alloy composite roll with pretightning force of the present invention refering to Fig. 1, it is a kind of with the hard of pretightning force
Matter alloy composite roll, including mandrel 1, spacer ring 2 and collars 3, one end of the mandrel 1 are provided with step 4, the collars 3 and spacer ring 2
Alternating is set on mandrel 1, and the other end of the mandrel 1 is provided with locking nut 5 and is used to spacer ring 2 and collars 3 being locked at mandrel 1
On.
As shown in Figure 1 and Figure 2, for the spacer ring 2 towards having circumferentially disposed annular groove 6 on the face of collars 3, annular is recessed
Groove 6 has two circles, and does not have certificate annular groove 6 to be provided with four ribs 8, and the rib 8 on different annular grooves 6 is radially staggered point
Cloth, and be respectively provided with towards the end face of the end face of collars 3 and locking nut 5 towards collars 3 in step 4 circumferentially disposed annular recessed
Groove 6, flexible preload piece 7 is all provided with all annular grooves 6, and elastic preload piece 7 uses rubber ring or flexible by other
Material manufacture, the height of the elastic preload piece 7 is more than the depth of annular groove 6, in order to preferably represent elastic pre- in Fig. 1
