Description
Technical field
The present invention relates to needle bearing manufacture fields, more particularly to a kind of needle bearing cage sizing die.
Background technique
In, large-scale needle bearing cage due to wall it is thin, intensity is relatively weak, can be deformed in processing, influences bearing and returns
Turn flexibility.Especially elongated cages for needle radial direction transmission amount is small more prominent, slightly deforms, and revolution flexibility is with regard to poor, shadow
Ring the quality of bearing, it is therefore desirable to radial shaping be done to product, eliminate roundness deformation.
Summary of the invention
In order to solve the above technical problems, passing through split type knot the present invention provides a kind of needle bearing cage sizing die
The setting of the application of structure and spring, linear guide solves the difficult point that retainer shaping encounters, and realizes the internal-and external diameter to retainer
Roundness deformation is eliminated in shaping simultaneously, guarantees that bearing turns round flexibility.
The technical solution adopted by the present invention to solve the technical problems is: a kind of needle bearing cage sizing die, it is wrapped
Include lower die and upper mold；The lower die includes lower template, and lower template is provided with low punch fixed plate, is provided in low punch fixed plate
Low punch；Cavity plate is additionally provided on the outside of low punch fixed plate；The bottom of cavity plate is provided with die socket, the die socket
Bottom and the sliding block for the linear guide being arranged in lower template are fixed；Conical ring is additionally provided on the cavity plate；The conical ring
Bottom surface and lower template between be additionally provided with first back-moving spring；Taper is respectively arranged in the position that the cavity plate and conical ring match
Face；The upper mold includes cope plate, and cope plate is provided with upper punch fixed plate, is provided with upper punch in upper punch fixed plate；Institute
It states cope plate and is additionally provided with pressing ring corresponding with conical ring；When molding, upper punch and low punch are collectively formed in retainer
The inside in shaping cavity face, cavity plate forms retainer outer wall shaping surface.
The top side of the cope plate is additionally provided with die shank.
Second back-moving spring is additionally provided between the die socket and low punch fixed plate.
Third spring is provided between the top and cope plate of the upper punch；The upper punch is in upper punch fixed plate
It floats and is arranged.
Guide post is additionally provided between the upper die and lower die；Described guide post one end is fixed in lower template, and the other end plugs
In conical ring, the pressing ring is also equipped with guide groove in position corresponding with guide post.
Beneficial effects of the present invention: a kind of needle bearing cage sizing die of the invention passes through answering for split type structure
It with the setting with spring, linear guide, solves the difficult point that retainer shaping encounters, realizes whole simultaneously to the internal-and external diameter of retainer
Shape eliminates roundness deformation, guarantees that bearing turns round flexibility.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of needle bearing cage sizing die of embodiment.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and examples and is further retouched in detail
It states, the embodiment is only for explaining the present invention, does not constitute and limits to protection scope of the present invention.
Embodiment
As shown in Figure 1, present embodiments providing a kind of needle bearing cage sizing die, it includes lower die and upper mold；Institute
Stating lower die includes lower template 1, and lower template 1 is provided with low punch fixed plate 4, low punch 9 is provided in low punch fixed plate 4；Position
Cavity plate 8 is additionally provided on the outside of low punch fixed plate；The bottom of cavity plate 8 is provided with die socket 6, the bottom of the die socket 6
It is fixed with the sliding block for the linear guide 3 being arranged in lower template 1；Conical ring 16 is additionally provided on the cavity plate 8；The conical ring
First back-moving spring 2 is additionally provided between 16 bottom surface and lower template 1；The position that the cavity plate 8 and conical ring 16 match is each
Tapered surface is set；The upper mold includes cope plate 10, and cope plate 10 is provided with upper punch fixed plate 12, in upper punch fixed plate 12
It is provided with upper punch 13；The cope plate 10 is additionally provided with pressing ring 11 corresponding with conical ring 16；When molding, upper punch 13
17 inner cavity shaping surface of retainer is collectively formed with low punch 9, the inside of cavity plate 8 forms 17 outer wall shaping surface of retainer；On described
The top side of template 10 is additionally provided with die shank 14；Second back-moving spring is additionally provided between the die socket 6 and low punch fixed plate 4
7；Third spring 15 is provided between the top and cope plate 10 of the upper punch 13；The upper punch 13 is in upper punch fixed plate
It floats and is arranged in 12；Guide post 5 is additionally provided between the upper die and lower die；Described 5 one end of guide post is fixed in lower template 1, separately
One end is plugged in conical ring 16, and the pressing ring 11 is also equipped with guide groove in position corresponding with guide post 5.
A kind of needle bearing cage sizing die of the present embodiment, when work, to shaping retainer set on the lower punch into
Row positioning, when upper mold downlink, upper punch and low punch integrator first forms complete working part, and then, upper mold continues
Downlink, pressing ring contact conical ring and common downlink, conical ring by the effect of tapered surface by cavity plate along linear guide to undershoot
Head position push, cavity plate laterally and under the action of complete retainer shaping；Then, upper mold uplink, cavity plate are multiple second
It moving and resets outward under the action of the spring of position, conical ring uplink and resets under the action of first back-moving spring, finally, on
