Another purpose of the present utility model is to provide a kind of metallic rotator structure, and punching press individual metals flabellum and combination can provide more flabellum, effectively are applied to the fan of multiple-airfoil type blade.
Another purpose of the present utility model is to provide a kind of metallic rotator structure, and linking each metal blade with juncture becomes the flabellum group, and is incorporated on the wheel hub, to obtain stable flabellum group body.
A purpose more of the present utility model is to provide a kind of metallic rotator structure, with the metal blade of metal forming, uses the phenomenon that does not also have buckling deformation down to produce in long-time high temperature.
To achieve these goals, the utility model provides a kind of metallic rotator structure, comprising: a plurality of metal blades, and those metal blades are combined into a flabellum group with fastening structure; And a wheel hub, the flabellum group that those metal blades are combined into is incorporated into this wheel hub.
The utility model provides a kind of metallic rotator structure in addition, comprising: a plurality of metal blades, those metal blades are bonded into a flabellum group; And a wheel hub, the flabellum group that those metal blades are bonded into is incorporated into this wheel hub.
The utlity model has following useful effect: the utility model is with a plurality of metal blades of metal stamping mode moulding, and links flabellum with fastening structure or other juncture and become a flabellum group, and this flabellum group is connected on the wheel hub.It is thin that the utility model makes flabellum thickness be emitted as far beyond plastic cement in the metal stamping mode, and pile up closeer, so can produce higher aerodynamic quality.
For further understanding feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended accompanying drawing only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

Embodiment
See also Fig. 1 and Fig. 2 A, 2B, the utility model provides a kind of metallic rotator structure, it can be applicable to radiation fan, comprise a plurality of metal blades 1 and a wheel hub 2, those metal blades 1 are the metallic stamping pieces that forms with continuous impact style punching out, to form other blade, the metal material of those metal blades 1 does not limit, and can be various materials such as aluminium, iron, steel or copper.Those metal blades 1 are limited angular and shape not, can be sweepforward blade, backward-swept blade or prismatic blade.
Those metal blades 1 can fastening structure or other juncture (as welding) be combined into a flabellum group, do not limit combination.In first embodiment of the present utility model, those metal blades 1 are to be combined into the flabellum group with fastening structure, that is on each metal blade 1, be provided with button 11 and button hole 12, button 11 and button hole 12 can be arranged at the top of metal blade 1, bottom margin or both sides of the edge etc. are located, button 11 and button hole 12 also can be arranged at other suitable position on the metal blade 1, button 11 and button hole 12 are corresponding pin threads, the box structure, in the present embodiment, the top in each metal blade 1 is formed with button 11 and button hole 12 near bending extension of place, both sides and punching out.Those metal blade 1 neat arrangements are piled up and are circular, utilize button 11 and button hole 12 mutual snappings between those metal blades 1, to form fastening structure, those metal blade 1 continuous snappings are piled up form the flabellum group, but fastening structure of the present utility model does not limit.
Those metal blades 1 are combined into after the flabellum group, are incorporated on the support 22 of hub body 21 or wheel hub 2 extensions with welding, plastic cement ejaculation or other combination again, do not limit its combination.In the present embodiment, this wheel hub 2 has a round hub body 21, the support 22 that these hub body 21 bottom margins stretch out and are formed with ring-type, and the flabellum group that those metal blades 1 are combined into is incorporated on this support 22 with welding manner, make the flabellum group be connected in wheel hub 2 peripheries.
See also Fig. 3 and Fig. 4 A, 4B, 4C, in second embodiment of the present utility model, those metal blades 1 also are to be combined into the flabellum group with fastening structure, that is on each metal blade 1, be provided with button 11 and button hole 12, button 11 and button hole 12 can be arranged at position suitable on the metal blade 1, in the present embodiment, the top in each metal blade 1 is formed with button 11 and button hole 12 near side place bending extension and punching out.Those metal blade 1 neat arrangements are piled up and are circular, utilize button 11 and button hole 12 mutual snappings between those metal blades 1, that is the button 11 of each metal blade 1 passes the button hole 12 of an adjacent metal blade 1, and contact in this button hole 12 outer rims with this button 11, to form fastening structure, those metal blade 1 continuous snappings are piled up form the flabellum group.
