In stamping process, the processing on above-mentioned inclined-plane curved face processing more of the prior art is simpler, and yield rate is high, and is convenient to install and use.
Preferred as technique scheme, the formed angle [alpha] of described inclined-plane and exterior bottom wall, 97 °≤α≤110 °.
Further preferred as technique scheme, 100 °≤α≤105 °.
Another purpose of the present utility model is to provide a kind of mould be used to processing aforesaid bearing outer ring, and this kind mould comprises upper die and lower die; Described patrix comprises external mold, is sheathed on the upper mold core in the described upper external mold; One end face of described upper mold core and the inwall of described upper external mold form active chamber; The shaped segment that the movement direction that the inwall of described upper external mold in described active chamber adds man-hour along workpiece is followed successively by guide section, is obliquely installed with guide section.
Be convenient to utilize the stamping process cold hobbing to be processed into the bearing outer ring that aforementioned outer side wall bottom has the inclined-plane of the exterior bottom wall of extending to.
Preferred as above-mentioned technology, described shaped segment and upper mold core are positioned at the formed angle beta of end face of active chamber, 97 °≤β≤110 °.
Further preferred as above-mentioned technology, 100 °≤β≤105 °.
Preferred as above-mentioned technology, described counterdie comprise that lower outer die casing is located at the lower mold core of described lower external mold, is sheathed on the mandrel in the described lower mold core.
Avoid on the one hand the distortion of bearing outer ring diapire, the demoulding after also being convenient on the other hand machine.
In sum, the utlity model has following beneficial effect: the utility model provides bearing outer ring simple in structure, and is easy to adopt the impact style preparation, and is convenient to install and use; The mould structure that the utility model provides is simple, is particularly suitable for processing aforesaid bearing outer ring.
