Description
Technical field
The utility model belongs to technical field of heat treatment, and in particular to a kind of super-huge biserial circular cone carburizing bearing outer ring heat
Mould is handled, is 45 suitable for raceway angles0Super-huge biserial circular cone carburizing bearing outer ring heat treatment secondary quenching.
Background technology
The phenomenon of appearance " holding " mould can be shunk inward during the secondary quenching cooling of carburizing bearing outer ring, need to be by using mould
Support set die quenching processing method control size harmomegathus and the deformation of inner surface.Need outer ring being enclosed on mould before quenching, one
Act oil groove quenching, carry out stripping operation is separated with mould after secondary quenching cooling end is fuel-displaced, then by outer ring.
Usually, the structural representation of the super-huge carburizing bearing outer ring mold of biserial circular cone is as shown in Figure 1；The structure
What middle die-face was supported is the roller surface of bearing outer ring, and raceway size and deformation are controlled with this；Due to raceway and stream oil groove
Laminating, raceway is adequately cooled during secondary quenching, and the purpose for ensureing heat treatment hardness is reached with this.
The bigger super-huge carburizing bearing outer ring of raceway angles, the cover die mode such as fitted with this mould with roller surface,
One side mould will have sizable power just to prop up " embracing mould " power that secondary quenching cooling is shunk inward, be supportted outward with reaching
Purpose firmly；The cooling of another aspect secondary quenching terminates rear lasso raceway and the stripping operation of mould is highly difficult, mould support rolling
The method in road face has not applied to the cover die processing of the structure outer ring；Existing raceway angles are 450The super-huge circle of biserial carburizing
The structural representation of axis of cone bearing outer-ring is as shown in Figure 2.
Utility model content
To solve trade company's technical problem, the purpose of this utility model is proposed outside a kind of super-huge biserial circular cone carburizing bearing
Enclose heat treatment die.
The utility model adopts the following technical scheme that to complete above-mentioned purpose：
A kind of super-huge biserial circular cone carburizing bearing outer ring heat treatment die, described heat treatment die to be setting up and down and
Structure identical two, each described mould has the semicircle ring structure of multiple boss that are uniformly distributed along the circumference for outside wall surface；It is described
The outside wall surface of mould is working face, and it with raceway angles is 45 that described working face, which is,0Super-huge biserial circular cone carburizing bearing
What the outer aperture surface of outer ring was directly contacted faces directly；The die bottom plate stream oil groove equal with being provided with width on working face；Described
The punishment that intersects of stream oil groove and working face is furnished with multiple fuel feed holes, and multiple described fuel feed holes are evenly distributed on die bottom plate circumference
Direction.
The diameter of the fuel feed hole is equal with stream oil groove width, and hole depth is equal with die bottom plate thickness.
The utility model proposes a kind of super-huge biserial circular cone carburizing bearing outer ring heat treatment die, raceway angles are
450The super-huge conic bearing outer ring of biserial carburizing prop up the outer internal diameter of outer ring with quenching mould, the working face of mould with it is outer interior
Footpath is fitted, and mould support face is outer aperture surface, and outer aperture surface is straight barrel type, and need to only be operated straight up and down during the demoulding just can be easily
Mould is separated with outer ring；Avoid the bump injury caused using external force to lasso, it is ensured that the surface quality of lasso；Die bottom plate
Fuel feed hole is designed, the raceway of outer ring is adequately cooled, and oil during secondary quenching is poured in outer ring raceway and mould from fuel feed hole
Between in the region that surrounds, contacted with roller surface, increase the cooling to raceway, it is ensured that raceway hardness.

Embodiment
The utility model is illustrated with reference to the drawings and specific embodiments：
As shown in figure 3, and combine Fig. 4, Fig. 5, a kind of super-huge biserial circular cone carburizing bearing outer ring heat treatment die is described
Heat treatment die be setting up and down and structure identical two, each described mould has multiple circumferentially equal for outside wall surface
The semicircle ring structure of cloth boss；The outside wall surface of the mould is working face 7, and it with raceway angles is 45 that described working face 7, which is,0
Super-huge biserial circular cone carburizing bearing outer ring facing directly of directly contacting of outer aperture surface；Die bottom plate 8 on working face 7 with opening
There is the stream oil groove 2 that width is equal；Multiple fuel feed holes 9 are furnished with stream oil groove 2 and the working face punishment that intersects, it is multiple described
Fuel feed hole 9 is evenly distributed on the circumferencial direction of die bottom plate 8.
The diameter of the fuel feed hole 9 is equal with the stream width of oil groove 2, and hole depth is equal with the thickness of die bottom plate 8.
The utility model is in use, be 45 by raceway angles0Biserial circular cone carburizing extra large size bearing outer ring smoothly put
On mould, wherein end face is fitted with bottom plate, and outer aperture surface is fitted with the working face of mould, during secondary quenching, outer ring
Enter after oil in oil play up and down with mould, to accelerate to quench cooling effect, quenching oil is from fuel feed hole during play up and down
Pour in the region that outer ring raceway face is surrounded with die-face, quenching oil is contacted with raceway, realization is filled to raceway
Divide cooling.After secondary quenching process terminates, outer ring is separated with mold releasability.
