Description
Technical field
The utility model belongs to Bearing Quenching technical field, and in particular to a kind of cageless circular cone carburizing bearing outer ring quenching
Use mould.
Background technology
Usually, raceway for full hypotenuse circular cone carburizing bearing outer ring structure schematic diagram as shown in Figure 1, quenching mould used
Lamps structure schematic diagram is as shown in accompanying drawing 2, Fig. 3.The location dimension design principle of mould is the Vehicle Processing chi according to narrow end surface raceway
It is very little to subtract tolerance determination.The phenomenon of appearance " holding " mould can be shunk inward during the secondary quenching cooling of carburizing bearing outer ring, use this
The set die quenching processing method of mould support inner surface is planted, because die-face supports the roller surface of bearing outer ring, mould
Location dimension（Ф moulds）Equal to the raceway size of outer ring narrow end surface（Ф）Subtract outside tolerance, the operating angle α and circular cone of mould
The raceway angles α of circle is consistent, and die-face coincide with outer ring raceway face shape, just can reach that control raceway size rises with this
Contracting and the purpose of deformation.
With shift in product mix, cageless bearing（The bearing of one section of straight flange of raceway band）It is more and more, cageless axle
The structural representation of bearing outer-ring is as shown in Figure 4；Such bearing outer ring ball track is made up of one section of straight flange and one section of hypotenuse, this knot
The carburizing bearing outer ring of structure, such as the outer ring raceway face shape using the quenching mould shown in accompanying drawing 2, then die-face and the structure
Shape can not be coincide, and directly resulting in raceway straight flange, hypotenuse cannot support, and size harmomegathus, deformation can not be controlled, and now use mould
Structure has not applied to the set die quenching of the structure outer ring.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose that a kind of cageless circular cone carburizing bearing outer ring is quenched
Fire mould.
The utility model adopts the following technical scheme that to complete above-mentioned purpose：
A kind of cageless circular cone carburizing bearing outer ring quenching mould, described mould is setting up and down, structure identical
Two；Each described mould has the semi-circular of multiple boss that are uniformly distributed along the circumference for outside wall surface；The outside wall surface of the mould is made
For working face, described working face includes the hypotenuse being obliquely installed from inside to outside and the straight flange being connected with described hypotenuse；Institute
Stream oil groove is additionally provided with the working face stated；Described stream oil groove is be uniformly distributed along the circumference multiple.
The utility model proposes a kind of cageless circular cone carburizing bearing outer ring quenching mould, mould in the mould structure
Working face matched with the raceway shape of the circular cone carburizing bearing outer ring of this one section of straight flange of raceway band, i.e. the working face of mould
It is also designed to one section of straight flange, one section of hypotenuse, rational size design can meet mold work simultaneously in face of straight flange, hypotenuse raceway
Support, has reached the purpose of control raceway size harmomegathus and deformation.

Embodiment
The utility model is illustrated with reference to the drawings and specific embodiments：
As shown in Fig. 4, Fig. 5, Fig. 6, a kind of cageless circular cone carburizing bearing outer ring quenching mould, described mould is
Setting up and down, structure identical two；Each described mould has the semi-circular of multiple boss that are uniformly distributed along the circumference for outside wall surface；
The outside wall surface of the mould as working face, described working face include the hypotenuse 7 that is obliquely installed from inside to outside and with it is described
Hypotenuse connection straight flange 6；Stream oil groove 5 is additionally provided with described working face；Described stream oil groove 5 is more for what is be uniformly distributed along the circumference
It is individual.
In terms of mold design：It is actual size at this that Ф 2, which is that raceway extends to size at end size, Ф 1 in drawing,.
The first step, has determined allowance referring initially to the sizes of Ф 2 during design mould location dimension compared with finished size, mould is can determine that afterwards
The theory orientation size Ф 2 ' of hypotenuse, second step has confirmed after Ф 2 ' that size Ф 1 subtracts tolerance and determines mould in 3 with reference to the accompanying drawings
The location dimension Ф 1 ' of straight flange, while Ф 1- Ф 1 ' >=Ф 2- Ф 2 ' need to be met
In terms of Making mold：When casting Vehicle Processing, first by being machined to Ф 2 ' in accompanying drawing 4, then by mould perpendicular to bottom surface
Car is to size Ф 1 '.Vehicle Processing size Ф 2 ' is must assure that in the process, and accurate Ф 1 ' can be just obtained afterwards.
