Block roller ring, the collars and spacer ring are alternately set on mandrel, and the locking end of the mandrel is provided with locking nut and is used for spacer ring
It is locked at collars on mandrel, the mandrel is gradually reduced from fixing end to locking end diameter.
The endoporus of the spacer ring and the endoporus of collars are truncated cone-shaped hole, the endoporus of the spacer ring and the endoporus of collars it is interior
Footpath is equal with the diameter of institute's installation site mandrel.
Taper of the mandrel from fixing end to locking end is 1 °~3 °.
Mandrel corresponding to the locking nut is provided with cylindrical thread.
Compared with prior art, the utility model has the advantages that：By the way that mandrel is gradual from fixing end to locking end diameter
The setting of reduction, the pretightning force of axial direction is produced to spacer ring and collars when spacer ring and collars are set on mandrel, in time in spacer ring
Gap is produced after getting rusty to keep collars not loose by the effect of pretightning force and locking nut, ensure that composite roll does not fail.
Preferably, the endoporus of the spacer ring and the endoporus of collars are truncated cone-shaped hole, the endoporus of the spacer ring and collars
The internal diameter of endoporus is equal with the diameter of institute's installation site mandrel, further increases collars and the contact area of spacer ring and mandrel, carries
High pretightening force, increase the stability of spacer ring and collars.
Preferably, taper of the mandrel from fixing end to locking end is 1 °~3 °, and taper, which is less than 1 °, can not provide enough
Axial pre tightening force, taper, which is more than 3 °, can cause axle diameter increase excessive, be unfavorable for and other assemblies coordinate.
Preferably, the mandrel corresponding to the locking nut is provided with cylindrical thread, and it is enough to ensure that locking nut also has
Coupling mechanism force.

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 hard alloy composite roll of the utility model refering to Fig. 1, Fig. 2, a kind of hard alloy composite roll,
Including mandrel 1, spacer ring 2 and collars 3, the mandrel 1 includes fixing end 4 and locking end 5, and the fixing end 4 is provided with step 6 to hinder
Block roller ring 3, the collars 3 and spacer ring 2 are alternately set on mandrel 1, and the locking end 5 of the mandrel 1 is used for provided with locking nut 7
Spacer ring 2 and collars 3 are locked on mandrel 1, the mandrel 1 is gradually reduced from fixing end 4 to the diameter of locking end 5.
As shown in Figure 3, Figure 4, further, the endoporus of the spacer ring 2 and the endoporus of collars 3 are truncated cone-shaped hole 8, it is described every
The internal diameter of the endoporus of ring 2 and the endoporus of collars 3 is equal with the diameter of institute installation site mandrel 1, i.e. the cone angle and core in truncated cone-shaped hole
The cone angle of axle fixing end to locking end is equal, and the endoporus of spacer ring and the endoporus of collars are intended to connect completely with the periphery of mandrel
Touch, the contact area that can further increase collars 3 and spacer ring 2 and mandrel 1 is so set, improve pretightning force, increase spacer ring 2 and roller
