Annular riveting mouth described above has the taper pushing tow face that the crimping that can make dust cover is crooked, rise outward.Simple in structure, can be fast, convenient the dust cover riveting is entered in the dustproof groove of offering on the bearing outer ring.
Another object of the present invention is to provide a kind of bearing double-side dustproof lid a technique for riveting, this technique can make two dust cover uniform stresseds and once be riveting in simultaneously on the bearing, raises the efficiency more than 60%.
Technique for riveting of a kind of bearing double-side dustproof lid is characterized in that comprising the steps:
1) two dust covers with bearing are preset in the dustproof groove that is opened in the bearing two end faces;
The bearing concentric locking collar that 2) will preset two dust covers is located on the guiding module post of riveting die described above and between upper stamping die and lower stamping die;
3) pressure head move down and pushing tow on stamping die along the downward slippage of guiding module post, the annular riveting mouth that makes stamping die and lower stamping die simultaneously respectively pushing be located at two dust covers of the bearing on the guiding module post, make the crimping of two dust covers crooked, rise outward and simultaneously riveting enters in the dustproof groove of offering on the bearing outer ring;
4) tear open and move bearing.
The present invention's technique can make two dust cover uniform stresseds also once be riveting in simultaneously on the bearing, raises the efficiency more than 60%.
