Abstract
The utility model discloses a cylindrical roller bearing retainer end face stamping die, which is composed of an upper stamping die, a supporting base, a large guide pole, a lower stamping die, fastening screw nails and a small guide pole. The supporting base and the middle position of the lower stamping die and the supporting base are fastened by the screw nails to form a lower module, the upper stamping die, the large guide pole and the small guide pole are in interference fit to form an upper module, the large guide pole, the small guide pole and the lower module are in clearance fit, and the outer circumference of supporting base is provided with circular pits which are distributed uniformly, wherein the amount of the circular pits is identical to that of roller bearings. The utility model has the advantages that the cylindrical roller bearing retainer end face stamping die can enable circumferences of the upper end face and the lower end face of the retainer to be pressed with equant circular-nest-shaped marks, can enable clearances between locked points and adjacent rolling bodies to be uniform, can lock rollers and increase revolution flexibility of bearings well, and is simple in structure and convenient in use.
Description
Affiliated technical field
The utility model belongs to the Equipment Technology field, especially a kind of design to cylindrical roller bearing holder end-face marking stamp.
Background technology
At present, this assembling mould is to manufacture experimently first, and optimizing design scheme because assembling is relatively more difficult, needs the tracking test process, accumulates experience, and lays the foundation for processing specification bearing of the same type from now on.
The flute profile retainer because of crossing deflection of beam and compression, makes retainer fenestra contraction in length in assembling process, after pressing lock null circle nest on the in-flanges, positions such as in-flanges and lock null circle nest have interference to be commonly called as clamp roll with roller, and bearing turns round very flexible.The revolution flexibility that the shape of retainer assembling back lock null circle nest and size directly influence bearing and whether can pin roller.
Summary of the invention
To influence the revolution of bearing flexibility and whether can pin roller in order to overcome, basis is novel to provide a kind of cylindrical bearing retainer end face impression to assemble mould.This assembling mould is under the effect of forcing press, and can make to be pressed on the upper and lower end face circumference of retainer between circular nested shape and lock point and the adjacent rolling element has uniform gap, and can pin roller well and design cylindrical roller bearing holder end-face marking stamp.The revolution flexibility that the impression of the circular nested shape of five equilibrium pins roller and improves bearing.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of cylindrical roller bearing holder end-face marking stamp, by patrix 1, supporting base 2, big guide pillar 3, dip mold 4, holding screw 5 and little guide pillar 6 are formed, between supporting base 2 and the dip mold 4 by the holding screw 5 fastening lower mold body groups of forming, form the upper die body group for interference fit between top die 1 and big guide pillar 3 and the little guide pillar 6, between big guide pillar 3 and little guide pillar 6 and dip mold 4 holes is matched in clearance, have on supporting base 2 excircles with the identical round nest of bearing roller number and evenly distribute, be used for equal portions roller and positioning action, when big guide pillar 3 in the top die 1 inserts the lower mold body group with little guide pillar 6, guarantee the upper die body group under itself weight effect, freedom slowly falls.
The beneficial effects of the utility model are, trying out in the process first, can make the impression that is pressed into the circular nested shape of five equilibrium on the upper and lower end face circumference of retainer, can make between lock point and the adjacent rolling element uniform gap is arranged, the revolution flexibility that can pin roller well and improve bearing, simple in structure and easy to use.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, top die, 2, supporting base, 3, big guide pillar, 4, dip mold, 5, holding screw, 6, little guide pillar.
The specific embodiment
As Fig. 1, the utility model is by patrix 1, supporting base 2, big guide pillar 3, dip mold 4, holding screw 5 and little guide pillar 6 are formed, between supporting base 2 and the dip mold 4 by the holding screw 5 fastening lower mold body groups of forming, form the upper die body group for interference fit between top die 1 and big guide pillar 3 and the little guide pillar 6, between big guide pillar 3 and little guide pillar 6 and dip mold 4 holes is matched in clearance, have on supporting base 2 excircles with the identical round nest of bearing roller number and evenly distribute, be used for equal portions roller and positioning action, when big guide pillar 3 in the top die 1 inserts the lower mold body group with little guide pillar 6, guarantee the upper die body group under itself weight effect, freedom slowly falls.
During impression, at first the end face with bearing assembly is placed on the lower mold body group, the distribution of roller relies on equally distributed round nest location in the supporting base 2, and then the upper die body group is placed on the bearing assembly upper surface, guide pillar will notice that big guide pillar 3 will align macropore after inserting the lower mold body group, little guide pillar 6 will align aperture, the upper die body group is under itself weight effect, by big guide pillar 3,6 guiding of little guide pillar, freedom slowly falls, when forcing press is suitable add external force F after, the equally distributed impression that the upper and lower end face of retainer can disposable extrusion Fig. 2.
