Abstract
The utility model discloses a novel impeller of a forward multi-wing centrifugal ventilator. The utility model is provided with a front and a back discs, wherein the front and the back discs are connected with a vane, and two ends of the vane are provided with rivet head feet. Punched holes which are corresponding to the rivet head feet are arranged on the front and the back discs. The rivet head feet are penetrated in the punched holes on the front and the back discs and perforate the punched holes on the front and the back discs, and the rivet head feet penetrate the part of the punched holes on the front and the back discs and are clamped on the front and the back discs in the deformed mode. The utility model has the advantages of reasonable structure, small blower vibration, low noise and high work efficiency, and the vane is firmly connected with the front and the back discs.
Description
Technical field:
The utility model relates to a kind of draught fan impeller.
Background technique:
Existing forward multiple wing centrifugal fan impeller, blade is to adopt on the dish of front and back jack is set with being connected of front and back dish, the two ends of blade are provided with insert head, before and after blade inserts behind the sheet, with insert head knock rivet-like one by one, be connected with front and back dish riveted type, such Placement, easily loosening, undesirable in conjunction with soundness, cause fan vibration big, noise is big.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and blade and forward and backward dish are connected firmly, and fan vibration is little, and noise is little, the forward multiple wing centrifugal ventilator novel impeller of high working efficiency.
Technical solution of the present utility model is:
A kind of novel impeller of forward multiple wing centrifugal ventilator, forward and backward dish is arranged, forward and backward dish is connected with blade, it is characterized in that: the two ends of blade are provided with the die pin, the perforation corresponding with the die pin is set on the forward and backward dish, die is worn in the perforation that is contained on the forward and backward dish, and penetrates the perforation on the forward and backward dish, and die was worn the part of boring a hole on the forward and backward dish and is clamped on the forward and backward dish with variant.
Die was worn the part of boring a hole on the forward and backward dish and was clamped on the forward and backward dish with 90 ° of bending variant.Die was worn the part of boring a hole on the forward and backward dish and also was welded to connect with forward and backward dish.Die was worn the part of boring a hole on the forward and backward dish and was clamped on the forward and backward dish with vertical half-twist variant.Between the dish of front and back, telophragma is set also, indent is set on the telophragma; The position that is connected with telophragma on the blade is provided with breach, and the blade breach is inserted in pressing connection in the telophragma indent.
The utility model is rational in infrastructure, and blade and forward and backward dish are connected firmly, and fan vibration is little, and noise is little, high working efficiency.
