Abstract
The utility model discloses a kind of ceramic roll, relate to CEMENTED CARBIDE PRODUCTION equipment technical field, it comprises the supporting-point roller being sleeved in rotating shaft, described supporting-point roller comprises a ladder axle sleeve and is set in ring-shaped pottery abaculus and the collar stop that described multidiameter puts, described multidiameter cover has descending the first shaft part being arranged in order of external diameter, the second shaft part and the 3rd shaft part, described ring-shaped pottery abaculus is set on described the second shaft part, on described the 3rd shaft part, be set with for being fixed the described collar stop of described ring-shaped pottery abaculus, the external diameter of described collar stop is identical with the external diameter of described the first shaft part, described ring-shaped pottery abaculus radially outward protrudes from described the first shaft part.The utility model compared with prior art, can solve existing ceramic roll because High Rotation Speed is overheated, easily pulls the problem of carbide alloy workpiece.
Description
Technical field
The utility model relates to CEMENTED CARBIDE PRODUCTION equipment technical field, especially a kind of roll for processing rigid alloy.
Background technology
The existing roll for processing rigid alloy comprises the metal supporting-point roller being sleeved in rotating shaft.Because this kind of metal roller produces high temperature in process of production, the working surface of roll supporting-point roller is easily overheated and workpiece is pulled in adhesion, affects machining accuracy, need to lower the temperature in addition, and complex process is wasted again resource; And roll is in the process running up, the coefficient of expansion of comparing with carbide alloy after the material of rotating shaft is heated is much larger, makes whole roll produce distortion, reduces machining accuracy, also easily causes the damage of carbide alloy workpiece; In addition, the easily wearing and tearing of the working face of supporting-point roller part, can only change whole supporting-point roller, cause the waste of resource.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of ceramic roll, to solve existing ceramic roll because High Rotation Speed is overheated, easily pulls the problem of carbide alloy workpiece.
In order to address the above problem, the technical solution of the utility model is: this ceramic roll comprises the supporting-point roller being sleeved in rotating shaft, described supporting-point roller comprises a ladder axle sleeve and is set in ring-shaped pottery abaculus and the collar stop that described multidiameter puts, described multidiameter cover has descending the first shaft part being arranged in order of external diameter, the second shaft part and the 3rd shaft part, described ring-shaped pottery abaculus is set on described the second shaft part, on described the 3rd shaft part, be set with for being fixed the described collar stop of described ring-shaped pottery abaculus, the external diameter of described collar stop is identical with the external diameter of described the first shaft part, described ring-shaped pottery abaculus radially outward protrudes from described the first shaft part.
In technique scheme, more specifically scheme can be: described ring-shaped pottery abaculus radially outward protrudes from 1.25 millimeters～2.7 millimeters of described the first shaft parts.
Further: described ceramic tesserae is calcium oxide ceramics abaculus.
Further: described ceramic tesserae is zircon ceramics abaculus.
Further: described ceramic tesserae is ceria oxide ceramics abaculus.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, this ceramic roll is by working face part and the overall separation of supporting-point roller, on setting-in, bear the abaculus of groundwork and the axle head abaculus in axle head outside, only need to change the working face partial response abaculus of main wearing and tearing, without changing whole supporting-point roller, reduced the wasting of resources; Adopt not only high temperature resistant but also low temperature resistant ceramic material as the material of the abaculus of groundwork, make whole roll using, ensure machining accuracy under high temperature and cold and cool environment;
2, the ring-shaped pottery abaculus of this ceramic roll, owing to having adopted thermal conductivity extreme difference, coefficient of expansion ceramic material seldom to make, has greatly reduced the probability that roll damages because of High Rotation Speed thermal expansion; Also the phenomenon that workpiece is pulled in the adhesion of almost having avoided roll heat conduction to cause simultaneously, has guaranteed machining accuracy, and without other cooling, technique is simple, saving resource, and production cost also reduces greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:
This ceramic roll as shown in Figure 1, it comprises the supporting-point roller 2 being sleeved in rotating shaft 1, supporting-point roller 2 comprises a ladder axle sleeve and is set in ring-shaped pottery abaculus 3 and the collar stop 4 that described multidiameter puts, described multidiameter cover has descending the first shaft part 2-1 being arranged in order of external diameter, the second shaft part 2-2 and the 3rd shaft part 2-3, ring-shaped pottery embedding 3 is set on the second shaft part 2-2, on the 3rd shaft part 2-3, be set with for being fixed the collar stop 4 of ring-shaped pottery abaculus 3, the external diameter of collar stop 4 is identical with the external diameter of the first shaft part 2-1, ring-shaped pottery abaculus 3 radially outward protrudes from height H=1.25 millimeter of the first shaft part 2-1.The material selection 35CrMo of the rotating shaft 1 here, the material selection 40Cr of supporting-point roller 2, No. 45 steel of material selection of collar stop 4.Ring-shaped pottery abaculus 3 is calcium oxide ceramics abaculus.
In other embodiments, ceramic tesserae can also be zircon ceramics abaculus, ceria oxide ceramics abaculus.As required, ring-shaped pottery abaculus 3 radially outward can protrude from the height of any one numerical value of 1.25 millimeters～2.7 millimeters of described the first shaft parts.
Claims (5)
1. a ceramic roll, comprise the supporting-point roller being sleeved in rotating shaft, it is characterized in that: described supporting-point roller comprises a ladder axle sleeve and is set in ring-shaped pottery abaculus and the collar stop that described multidiameter puts, described multidiameter cover has descending the first shaft part being arranged in order of external diameter, the second shaft part and the 3rd shaft part, described ring-shaped pottery abaculus is set on described the second shaft part, on described the 3rd shaft part, be set with for being fixed the described collar stop of described ring-shaped pottery abaculus, the external diameter of described collar stop is identical with the external diameter of described the first shaft part, described ring-shaped pottery abaculus radially outward protrudes from described the first shaft part.
