Description
Technical field
The utility model relates to Production of bearing technical field, relates in particular to the cold rolling mould of a kind of oscillating bearing lasso.
Background technology
Oscillating bearing is a kind of sliding bearing, mainly an inner ring by spherical outside surface and an outer ring by Internal Spherical Surface, consists of, and the Internal Spherical Surface of outer ring and the spherical outside surface of inner ring form sliding friction pair.Thereby the inner ring of oscillating bearing and outer ring be provided with annular oil groove and radial direction oil hole, make lubricator mass-energy arrive friction position by oil groove and oilhole.At present, the inside and outside circle processing of oscillating bearing, main employing turning moulding, need the inside and outside circle of car and end face, also want deburring, car two ends fillet, car oil groove, former technique process is loaded down with trivial details and the process-cycle is long, spillage of material large (comprising cutter, frock etc.), later process surplus is large, and machining accuracy is wayward, quality is unstable.
Utility model content
For the above-mentioned problems in the prior art, technical problem to be solved in the utility model is to provide a kind of oscillating bearing lasso cold rolling mould, and it can replace turning moulding, and manufacturing procedure obviously reduces, and easy to operate; Reduced the spillages of material such as cutter, frock, saved labour turnover and management cost, machine-shaping precision is high.
The technical solution of the utility model is as follows: the cold rolling mould of a kind of oscillating bearing lasso, comprise core roller and roll milling wheel, described core roller is provided with annular outer mold surface, described roll milling wheel is provided with annular indent profile, described indent profile is corresponding with position and the width of outer mold surface, in described indent profile, establish bossed ring, the two ends root of described outer mold surface and indent profile has rounding or chamfering.
Further, the two sides of described ring are inclined-plane, and ring top width is less than ring root width.
Further, the two ends root of described outer mold surface and indent profile has rounding, and the radius of corner of indent profile is greater than outer mold surface radius of corner.
Further, the ring-shaped periphery of described indent profile is sphere or the face of cylinder.
Further, described outer mold surface has the sphere of evagination.
The beneficial effects of the utility model are: by cold rolling mould, realize the shaping of oscillating bearing inner ring or outer ring, need not realize inner circle, cylindrical by multiple turning operation, oil groove and rounding processing, can realize inner circle, cylindrical simultaneously, the moulding of oil groove and rounding, manufacturing procedure obviously reduces, and easy to operate; Reduce the loss of cutter and frock, also reduced cost of labor, management cost; Machining accuracy is high, and dimensional accuracy, roughness and the form and position tolerance of main finished surface can stably meet or exceed Vehicle Processing level; And the metal structure local flow of spreading portion, lattice is organized finer and close, has improved fatigue resistance, has improved the inherent quality of workpiece comprehensively, and bearing significantly improves service life, also can realize automation, configuration automatic production line.

The specific embodiment
Below with reference to accompanying drawing, preferred embodiment of the present utility model is elaborated.
As depicted in figs. 1 and 2, the outer ring 3 of oscillating bearing has Internal Spherical Surface, and 4 of inner rings have spherical outside surface, and at the periphery of outer ring 3,, be provided with oil groove 5 on the inside and outside disc of inner ring 4, oilhole 6 radially runs through the inside and outside surface of inner ring or outer ring from oil groove 5.
Embodiment 1: as shown in Figures 3 to 5, this is the mould that spreading oscillating bearing outer ring 3 is used, comprise core roller 1 and roll milling wheel 2, described core roller 1 is provided with annular outer mold surface 11, the outer mold surface 11 of annular is consistent with the interior hole shape of outer ring 3, described roll milling wheel 2 is provided with annular indent profile 21, described indent profile 21 is corresponding with position and the width of outer mold surface 11, described indent profile 21 is consistent with the outer round surface shape of outer ring 3, the present embodiment is the cold rolling mould that is applied to outer ring 3, the ring-shaped periphery of roll milling wheel 2 indent profiles 21 is the face of cylinder, at the middle part of indent profile 21, establish bossed ring 211, ring 211 can extrude annular oil groove 5 on the outer surface of workpiece, the two sides of ring 211 are inclined-plane, encircle 211 top width and be less than ring root width, oil groove 5 bottoms that press out like this have poly-functional oil.The two ends root of described outer mold surface 11 and indent profile 21 has rounding or chamfering, in the present embodiment, rounding preferably, indent profile fillet 212 radiuses are greater than outer mold surface fillet 112 radiuses, extrude once the rounding of bearing outer ring both sides, the chamfering radius of bearing outer ring cylindrical is greater than the chamfering radius of endoporus.As shown in Figure 3 and Figure 5, described outer mold surface 11 has the sphere 111 of evagination, and spreading goes out the Internal Spherical Surface of outer ring 3.
Embodiment 2: the structure of the included parts of the present embodiment, and the position relationship between each parts is substantially the same manner as Example 1, difference is the oscillating bearing inner ring being applied to as shown in Figure 2, cold rolling mould comprises core roller and roll milling wheel, core collars shape outer mold surface is consistent with the interior hole shape of inner ring 4, indent profile set on roll milling wheel is consistent with the outer ring surface shape of inner ring 4, just leaves certain surplus for following process.
These are only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
