Abstract
The utility model provides a ball guide rail forming shaft in bearing, including forming die core and molding sleeve, forming die core is solid cylindrical structure, and molding sleeve is the cylindrical structure of well casement, and molding sleeve overlaps on forming die core to with forming die core interference fit, the last forming groove that has seted up of molding sleeve, forming groove are the annular structure, and forming groove, forming die core and molding sleeve cooperate and accomplish the interior ball guide rail's of bearing shaping. The utility model provides a forming shaft is used for the shaping of bearing ball guide rail, and its is rational in infrastructure, and convenient operation has improved the shaping precision of guide rail effectively, has reduced because of wearing and tearing, and the long -time precision that causes of using descends, and the product is unqualified, and simultaneously, this forming shaft be detachable connection, but reuse, the the cost is reduced input.
Description
Technical field
This utility model is related to hot forged mould technical field, and in particular to spherical guide shaping axle in a kind of bearing.
Background technology
The one kind of roller bearing as bearing, is widely used in the fields such as various big machineries, vehicle, in roller bearing
Roller be to be produced using pressing in the prior art, material is made into stamping mold first, the shape of mould with to add
Then material is squeezed into predetermined shape using drift and die by the form fit of work roller.
At present, in use because of discontinuity, easily there is expansion, even slight crack in the mould on market,
Service life is short, existing seriously to reduce the quality of production, increased production cost.Simultaneously as bearing specification is various, each
Molding sleeve can only be directed to a kind of bearing of specification, therefore, after molding, it is impossible to reuse, waste of resource.
Therefore, for the problems referred to above, the utility model proposes a kind of new technical scheme.
Utility model content
The purpose of this utility model is to provide a kind of simple structure, and easy to operate, formed precision reduces disqualification rate,
Production efficiency is improve, spherical guide shaping axle in the bearing of cost production cost.
This utility model is achieved through the following technical solutions：
Spherical guide shaping axle in a kind of bearing, including formation die core and molding sleeve, the formation die core is solid cylinder
Shape structure, the molding sleeve are hollow circular cylindricality structure, and the molding sleeve is placed on formation die core, and is matched somebody with somebody with formation die core interference
Close, on the molding sleeve, offer shaping groove, shaping groove is circulus, the shaping groove, formation die core and molding
Set is engaged the molding for completing spherical guide in bearing.
Further, described molding sleeve one end is provided with guide section, and the guide section is conical structure.
Further, described formation die core one end offers locating slot.
Further, described formation die core one end offers passage.
Further, the shaping groove inner surface is circular arc type structure.
Further, between the molding sleeve and formation die core it is detachable installation.
The beneficial effects of the utility model are：The utility model proposes shaping axle be used for bearing ball guide rail molding,
Which is rational in infrastructure, easy to operate, be effectively improved the formed precision of guide rail, reduces because of abrasion, for a long time using causing
Precise decreasing, product are unqualified, meanwhile, this shaping axle is detachable connection, repeats and utilizes, reduces cost input.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Wherein：1st, formation die core, 2, molding sleeve, 3, shaping groove, 4, guide section, 5, locating slot, 6, passage.
Specific embodiment
Illustrate below in conjunction with the accompanying drawings to be described further this utility model.
As shown in figure 1, spherical guide shaping axle in a kind of bearing, including formation die core 1 and molding sleeve 2, formation die core 1 is
Solid cylindrical configuration, molding sleeve 2 are hollow circular cylindricality structure, and molding sleeve 2 is placed on formation die core 1, and with 1 mistake of formation die core
It is full of cooperation, on molding sleeve 2, offers shaping groove 3, shaping groove 3 is circulus, shaping groove 3, formation die core 1 and molding
Set 2 is engaged the molding for completing spherical guide in bearing.
In the present embodiment, 2 one end of molding sleeve is provided with guide section 4, and guide section 4 is conical structure.
In the present embodiment, 1 one end of formation die core offers locating slot 5.
In the present embodiment, 1 one end of formation die core offers passage 6.
In the present embodiment, 3 inner surface of shaping groove is circular arc type structure.
In the present embodiment, between molding sleeve 2 and formation die core 1 it is detachable installation.
The utility model proposes shaping axle be used for bearing ball guide rail molding, which is rational in infrastructure, easy to operate, effectively
Improve the formed precision of guide rail, reduce because of abrasion, for a long time using the precise decreasing for causing, product is unqualified, meanwhile,
This shaping axle is detachable connection, repeats and utilizes, reduces cost input.
Preferred embodiment of the present utility model is the foregoing is only, this utility model is not limited to, for this
For the technical staff in field, this utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. are should be included within protection domain of the present utility model.
