Description

Novel connection impeller

Technical Field

The utility model belongs to the technical field of lampblack absorber equipment, specifically relate to a novel connect impeller.

Background

The prior art of the impeller of the range hood has the following problems: the structure problem can not realize large caliber, large size and large air quantity; the structure is unreasonable, so that the deformation is easy to occur and the balance is poor; the whole impeller structure is divided into four parts, namely an upper blade fixing piece, a lower blade fixing piece and a middle blade fixing piece, wherein the upper blade fixing piece and the lower blade fixing piece are punched by flat plates in the prior art, so that the flatness is difficult to guarantee, the strength is low, and the upper blade fixing piece and the lower blade fixing piece are easy to deform due to the difference in strength after being assembled into a component; the blade stator and the blade installation in the present double-deck impeller technique are fixed by rolling to make the blade take place plastic deformation, and this kind of fixed mode connection is relatively not firm.

Disclosure of Invention

The utility model discloses solve the technical problem that above-mentioned prior art exists, provide a novel connection impeller.

The above technical problem of the utility model is mainly solved through the following technical scheme: the utility model provides a novel connect impeller, includes wheel hub, bladed disk and two sets of spinning structures, its characterized in that: the diameter of the hub is consistent with that of the blade disc, the blade disc is sleeved on the hub, a plurality of blades and air inlets which are integrally formed through punching are arranged on the blade disc in an annular array mode, one spinning structure is sleeved on an upper end disc opening of the blade disc and connected with the blade disc through spinning riveting, and the other spinning structure is sleeved on a connecting portion of the blade disc and the hub and enables the spinning structure and the blade disc to be in spinning riveting.

Preferably, the flow-formed structure comprises a stiffening ring.

Preferably, the spun structure comprises a plurality of individual stiffening plates.

Preferably, a plurality of independent reinforcing plates are connected end to end at the connection part of the blade disc, the hub and the blade disc in a spinning riveting mode.

Preferably, a connecting sleeve is arranged at the center of the hub and fixedly connected with the hub.

Preferably, the reinforcing ring comprises a flanging formed by spinning riveting, and the angle of the flanging is 0-90 degrees.

The utility model discloses beneficial effect who has: through setting up the bladed disk, utilize the form of punching press to process out the blade on the bladed disk, blade and bladed disk be whole mechanism, very big reinforcing the intensity of blade, through spinning riveted form with two beaded finish levels at the upper and lower both ends of bladed disk, the intensity of enhancement blade that can step forward.

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of a reinforcement ring of the present invention comprising a plurality of reinforcement plates;

fig. 3 is a schematic structural view of the different angle flanges of the present invention.

In the figure: 1. a hub; 2. a bladed disk; 3. a reinforcement ring; 4. a blade; 5. an air inlet; 6. a reinforcing plate; 7. connecting sleeves; 8. and (5) flanging.

Detailed Description

The technical solution of the present invention is further specifically described below by way of embodiments and with reference to the accompanying drawings.

Example (b): the utility model provides a novel connect impeller, as shown in fig. 1-3, includes wheel hub 1, bladed disk 2 and two sets of spinning structures, wheel hub 1's diameter is unanimous with bladed disk 2's diameter, bladed disk 2 overlaps on wheel hub 1, annular array has a plurality of blades 4 and air intake 5 through punching press integrated into one piece on bladed disk 2, one of them spinning structure overlaps in the last dish mouth of bladed disk 2 to be connected with bladed disk 2 through spinning riveting, another spinning structure overlaps in the junction of bladed disk 2 and wheel hub 1 to through spinning riveted form with spinning structure and bladed disk 2.

The spinning structure comprises a reinforcing ring 3; the spinning structure comprises a plurality of independent reinforcing plates 6, the independent reinforcing plates 6 are connected end to end at the joints of the blade disc 2, the hub 1 and the blade disc 2 in a spinning riveting mode, a connecting sleeve 7 is arranged at the center of the hub 1, the connecting sleeve 7 is fixedly connected with the hub 1, the reinforcing ring 3 comprises a turnup 8 formed by spinning riveting, and the angle of the turnup 8 is 0-90 degrees.

The principle of the utility model is as follows: firstly, take the stainless steel board of suitable width, equidistance punching press out blade 4 and air intake 5 on the stainless steel board, the stainless steel board that buckles during punching press air intake 5 forms blade 4, it forms bladed disk 2 to make the stainless steel board after the punching press circular, with bladed disk 2 cover on wheel hub 1, again with two beaded finish 3 covers on bladed disk 2, connect it on bladed disk 2 through spinning riveted form, because beaded finish 3 is the loop configuration, can produce great waste material in the time of manufacturing, consequently still can set the beaded finish 3 into by the combination of polylith reinforcing plate 6, can effectively reduce the production of waste material.

The angle of the flanging 8 is between 0 and 90 degrees, the angle of the flanging 8 is gradually reduced and increased according to the number of the blades 4, when the number of the blades 4 is 20, the optimal angle of the flanging 8 is 30 degrees, when the number of the blades 4 is 40, the optimal angle of the flanging 8 is 60 degrees, and when the number of the blades 4 is 60 degrees, the optimal angle of the flanging 8 is 90 degrees.

Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above-described embodiments, and many modifications are possible. Any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention should be considered as belonging to the protection scope of the present invention.
