Abstract
The invention relates to a combined centrifugal fan impeller comprising an impeller front disc, impeller blades and an impeller rear disc, wherein lower edges of the impeller blades are provided with flanging structures; the outer side of the impeller rear disc is provided with through holes with shapes consistent with the impeller blades and flanging combining structures capable of accommodating the flanging structures; slot structures with shapes consistent with the impeller blades are arranged on the impeller front disc; and the impeller blades pass through the through holes and are fixedly connected on the combining surface between the impeller front disc and the impeller rear disc. The combined centrifugal fan impeller disclosed by the invention has higher twist and stretch resistance and is particularly suitable for the manufacturing of high-revolution centrifugal impellers. In addition, the slot and insertion hole structures of the impeller front disc and the impeller rear disc and the flanging structures of the impeller blades are integrally manufactured, so that the process of manufacturing the slot, the insertion hole or the flanging twice is saved and the labor is saved.
Description
Technical field
The present invention relates to the centrifugal impeller on the centrifugal blower, specifically a kind of Combined centrifugal fan impeller with higher anti-twist tensile property.
Background technique
Centrifugal impeller is a vitals on the centrifugal blower, because centrifugal impeller is difficult to the special construction of global formation, so the making of present domestic centrifugal blower fan blade wheel is take combined type as main, namely by the impeller shroud, impeller blade and impeller hub disk three parts form, impeller blade is fixed between impeller shroud and the impeller hub disk by welding or bonding mode, but in use there is very large defective in existing this centrifugal impeller, often be combined the bad situation that fracture of root occurs with shroud or hub disk owing to blade during the centrifugal impeller High Rotation Speed, especially on high revolution centrifugal blower, this defective is more obvious.And, weld or bonding fixation method, can not guarantee the anti-twist tensile property of centrifugal impeller integral body.
Summary of the invention
Purpose of the present invention just provides a kind of centrifugal blower fan blade wheel, is combined problem firm not and that the whole anti-twist tensile property of centrifugal blower fan blade wheel is lower with impeller shroud or impeller hub disk to solve blade that existing centrifugal blower fan blade wheel exists.
The object of the present invention is achieved like this: a kind of Combined centrifugal fan impeller, formed by impeller shroud, impeller blade and impeller hub disk, described impeller blade lower edge is shaped with turnup structure, be shaped with the perforation that coincide with described impeller blade shapes and the flange combining structure that can hold described turnup structure in the described impeller hub disk outside, be shaped with the inserting slot construction that coincide with described impeller blade shapes at described impeller shroud; Described impeller blade passes described perforation, and described impeller blade passes described perforation, and the junction plane place between described impeller blade and described impeller shroud and the described impeller hub disk is affixed.
Be shaped with boss in the described impeller hub disk around the side perforation.
Inserting slot construction on the described impeller shroud is to be shaped with the long strip groove in impeller shroud inboard.
As another implementation, the inserting slot construction on the described impeller shroud is to be shaped with boss in impeller shroud inboard, is shaped with slot at described boss.
Junction plane place between described impeller blade and described impeller shroud and the described impeller hub disk is undertaken affixed by sticker layer.
As another implementation, the junction plane place between described impeller blade and described impeller shroud and the described impeller hub disk is undertaken affixed by welding.
The end band turnup structure that impeller blade of the present invention is combined with the impeller hub disk, can prevent that like this impeller blade and impeller hub disk are because extracting out in conjunction with bad, and both increased the junction plane of impeller blade and impeller hub disk, increased again the stress surface of impeller hub disk to blade, thereby increased the anti-twist tensile property of centrifugal blower fan blade wheel integral body, be particularly suitable for the making of high revolution centrifugal impeller.The impeller blade upper end is affixed with the inserting slot construction on the impeller shroud, has further increased the steadiness of centrifugal blower fan blade wheel integral body.In addition, the turnup structure of slot, jack structure and the impeller blade of impeller shroud, impeller hub disk all is one-body molded manufacturings, has saved the process that secondary is made slot, jack or flange, saves artificial.

As a kind of improvement mode of execution to centrifugal blower fan blade wheel illustrated in fig. 1, as shown in Figure 2, be around the slot of impeller shroud 1, to be shaped with shroud boss 6, to increase the junction plane of impeller blade and impeller shroud.
As the another kind of centrifugal blower fan blade wheel illustrated in fig. 1 is improved mode of execution, as shown in Figure 3, be around the perforation of the internal surface of impeller hub disk 3, to be shaped with hub disk boss 5, to increase the junction plane of impeller blade and impeller hub disk.
As a kind of improvement mode of execution to the optimum of centrifugal blower fan blade wheel illustrated in fig. 1, as shown in Figure 4, be around the slot of impeller shroud 1, to be shaped with simultaneously shroud boss 6, and around the perforation of the internal surface of impeller hub disk 3, be shaped with hub disk boss 5.
The flanging 4 of impeller blade 2 of the present invention also can be made the hook-shaped structure that has as shown in Figure 5, perhaps can make the form with one-sided flanging.
