Abstract
The utility model discloses a kind of Separated type spring Die for pressing cap of pressing bearing dust cover, comprise external pressure cover mold, the alignment axis that can move axially is connected with by core bar in described external pressure cover mold, described outer core bar is equipped with spring between described external pressure cover mold and alignment axis, the two ends of described spring abut with alignment axis and external pressure cover mold respectively, when alignment axis is subject to upward force, alignment axis moves up together with the relative external pressure cover mold of core bar, and spring is compressed and plays buffer function.When press-fiting dust cover, pressure is delivered to alignment axis by external pressure cover mold by spring, utilizes the elasticity of spring that the impact force press-fiting process is steadily increased, reduces the impact to bearing dustproof cover, and then the distortion that reduction bearing is caused owing to impacting, the external diameter effectively reducing bearing is oval.The utility model improves dust cover assembly qualified rate, reduces bearing mnanufacture cost, increases economic efficiency.
Description
Technical field
The utility model relates to a kind of Separated type spring Die for pressing cap of pressing bearing dust cover.
Background technique
What current bearing press mounting dust cover adopted is integral type Die for pressing cap, shown in Figure 5, integral type Die for pressing cap comprises the Die for pressing cap 6 of one, Die for pressing cap 6 is provided with gland angle 61, be rigid contact press-fiting integral type Die for pressing cap and dust cover in process, pressure directly acts on dust cover by gland angle 61, and the impact force that dust cover is subject to is large, and then cause bearing outer ring external diameter to be out of shape, produce oval; Meanwhile, press-fit dust cover discontinuity in process because dust cover race deformation causes, easily deformation of unevenness occurs, appearance quality is bad, has a strong impact on quality of product.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of Separated type spring Die for pressing cap of pressing bearing dust cover.
The utility model solves the technological scheme that its technical problem adopts:
A kind of Separated type spring Die for pressing cap of pressing bearing dust cover, comprise external pressure cover mold, the alignment axis that can move axially is connected with by core bar in described external pressure cover mold, described core bar is equipped with spring between described external pressure cover mold and alignment axis, the two ends of described spring abut with alignment axis and external pressure cover mold respectively, when alignment axis is subject to upward force, alignment axis moves up together with the relative external pressure cover mold of core bar, and spring is compressed and plays buffer function.
As the improvement of technique scheme, described external pressure cover mold inside is provided with the first inner chamber, described first inner chamber and alignment axis outer ring corresponding matching.
Further, outer ring, described alignment axis lower end surface is provided with when alignment axis falls for pushing down the annular boss of plane of a loop in bearing dustproof cover.
Further, described alignment axis lower center is provided with boss, and described boss coordinates with brearing bore.
Further, described boss center arranges tapped hole, and core bar is installed on described tapped hole top, and described core bar can be hexagon socket head cap screw.
Further, described external pressure cover mold inside is provided with the second inner chamber, and described second inner chamber and spring outer ring size corresponding matching, spring is held in described second inner chamber at least partly.
The beneficial effects of the utility model are: this device is Separated type spring Die for pressing cap, by the buffering of spring, the rigid stamp press-fiting process is become flexible punching press, the impact force that dust cover is subject to diminishes, press-fit process more steady, make dust cover smooth, be mounted in the dustproof groove of bearing in good condition; On the other hand, reduce impact force, the amount of deformation of bearing outer ring is effectively controlled, bearing outer ring external diameter ellipse is down to 2 ~ 4 μm by 7 ~ 10 μm, and effectively improve bearing outside diameter distortion, dust cover also can keep smooth preferably, improves Total Product quality.

Embodiment
Referring to figs. 1 through Fig. 4, a kind of Separated type spring Die for pressing cap of pressing bearing dust cover, it is characterized in that: comprise external pressure cover mold 1, the alignment axis 2 that can move axially is connected with by core bar 4 in described external pressure cover mold 1, described outer core bar 4 is equipped with spring 3 between described external pressure cover mold 1 and alignment axis 2, the two ends of described spring 3 abut with alignment axis 2 and external pressure cover mold 1 respectively, when alignment axis 2 is subject to upward force, alignment axis 2 moves up together with the relative external pressure cover mold of core bar, and spring is compressed and plays buffer function.When press-fiting dust cover, pressure is delivered to alignment axis 2 by external pressure cover mold 1 by spring 3, utilize the elasticity of spring 3 that the impact force press-fiting process is steadily increased, reduce the impact to bearing dustproof cover, and then the distortion that reduction bearing is caused owing to impacting, effectively reduce the external diameter ovalizing deflection of bearing.
In the present embodiment, preferably, described external pressure cover mold 1 inside is provided with the first inner chamber 11, described first inner chamber 11 and alignment axis 2 outer ring corresponding matching.This structure improves the assembling concentricity of external pressure cover mold 1 and alignment axis 2, accurate positioning when ensureing that Die for pressing cap press-fits dust cover.
In the present embodiment, preferably, outer ring, described alignment axis 2 lower end surface is provided with when alignment axis falls for pushing down the annular boss 21 of plane of a loop in bearing dustproof cover.Described annular boss 21 is equal with the inner ring plane sizes of dust cover, first contacts plane of a loop in dust cover press-fiting annular boss 21 in process, promotes that dust cover is smooth, intact to be embedded in the dustproof groove of bearing.
In the present embodiment, preferably, alignment axis 2 lower center is provided with boss 22, and described boss 22 coordinates with brearing bore, and this structure makes Die for pressing cap and bearing accurate positioning.
In the present embodiment, preferably, described boss 22 center arranges tapped hole 23, and core bar 4 is installed on described tapped hole 23 top, and described core bar 4 can be hexagon socket head cap screw.Core bar 4 is fixedly connected with screw thread with alignment axis 2, and adjust core bar 4 screw in the degree of depth of apotting spindle 2 can the pretightening force of Regulation spring 3, to meet the different needs.
In the present embodiment, preferably, described external pressure cover mold 1 inside is provided with the second inner chamber 11, and described second inner chamber 11 and spring 3 outer ring corresponding matching, spring 3 is held in described second inner chamber at least partly.This structure makes spring 3 radial location accurate, eliminates because spring 3 is press-fiting rocking in process, the bending and phenomenon of dust cover discontinuity that causes.
The above; just better embodiment of the present utility model; but this model utility is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, all should fall within protection domain of the present utility model.
