Embodiment
As shown in Figure 1 and Figure 2, the utility model support bladed impeller, comprises blade cylinder 2, and the both ends of the surface of blade cylinder 2 are fixedly connected with end circle 3 respectively; Annular mid-game 1 is fixedly connected with in the middle part of the cavity of blade cylinder 2; The center hole of annular mid-game 1 is fixedly installed axle sleeve 5; Axle sleeve 5 is fixedly connected with running shaft by Cock screw 4, realizes being fixedly connected with of impeller and running shaft;
Offer annular notches 24 in the middle part of the inner ring of blade cylinder 2, annular notches 24 is for the location of annular mid-game 1;
Annular mid-game 1 is made up of disk body in two panels, and two panels mid-game body overlaps, and forms Y-shaped structure in outer rim, and the maximum outside diameter of annular mid-game 1 is slightly larger than the maximum outside diameter of annular notches 24;
During assembling, the Y-shaped outer rim of annular mid-game 1 snaps in this annular notches 24, because the maximum outside diameter of annular mid-game 1 is slightly larger than the maximum outside diameter of annular notches 24, annular mid-game 1 is made to have the elasticity of outwards support, thus annular mid-game 1 is lock onto in blade cylinder 2, realize being fixedly connected with of annular mid-game 1 and blade cylinder 2.
As shown in Figures 3 to 5, blade cylinder 2 is made up of multiple blade unit; As shown in Figure 6, each blade unit comprises radial extension part 21, circumferential extensions 22, and radial extension part 21 is arranged in a crossed manner with circumferential extensions 22, the formation folded part, one end 23 of circumferential extensions 22; Blade unit is fixedly connected with adjacent blade unit by the folded part 23 of circumferential extensions 22 one end, and the circumference realizing multiple blade unit is fixedly connected with, and forms the blade cylinder 2 of tubular;
The outer rim formation spoon connected in star 31(of end circle 3 and the cross section of groove 31 are the spoon shape of a side opening, and as shown in Figure 6), spoon connected in star 31 is for being fixedly connected with the folded part 23 of blade cylinder 2;
Folded part 23, for the spoon connected in star of insertion end circle 3 outer rim, realizes blade cylinder 2 and holds being fixedly connected with of circle 3.
The manufacture method of the utility model support bladed impeller, comprises the following steps:
The first step, makes the expansion blade for the formation of blade cylinder 2;
By the progressive die to the disposable impact briquetting of rectangular plate, form integrated type and launch blade; As shown in Figure 5, launch blade and comprise multiple blade unit connected successively in linearly arranged; Owing to being formed with folded part 23 between adjacent blade unit, this folded part 23 can make the pitch reduction of blade, to reach the designing requirement of wide blade;
Second step, makes two end circles 3;
By mould to the disposable impact briquetting of dish type sheet material, form end circle 3, and form spoon connected in star 31 in the outer rim of end circle 3;
3rd step, makes disk body in the two panels of annular mid-game 1;
Form a circle alice (this alice is a wing of Y-shaped structure, and in two panels, namely the alice of disk body forms Y-shaped structure back-to-back) in the outer rim of middle disk body, and form a circle protruding 11 in the inner side of outer rim;
This circle projection 11 can make annular mid-game 1 have outward extending surplus, after this projection 11 is driven plain, the external diameter of annular mid-game 1 increases, the outer rim of annular mid-game 1 outwards stretches, thus fully can contact with the annular notches 24 of blade cylinder 2 inner ring, realize being fixedly connected with of annular mid-game 1 and blade cylinder 2;
Middle disk body can adopt the clout of manufacturing terminal circle 3 to process, to improve stock utilization;
4th step, assembling axle sleeve 5 and annular mid-game 1;
Two panels mid-game body weight is folded, and makes axle sleeve 5 through disk body in two panels and rivet, disk body in two panels is connected, forms annular mid-game 1;
5th step, assembling impeller;
As shown in Figure 7, one of them end circle 3 of horizontal, makes the opening up of the spoon connected in star 31 of end circle 3; Fixture inner core counterdie 6 is arranged on end circle 3;
The external diameter of fixture inner core counterdie 6 is less than the external diameter of end circle 3, and the height of fixture inner core counterdie 6 is the axial distance between annular mid-game 1 and end circle 3;
As shown in Figure 8, the annular mid-game 1 that axle sleeve 5 is housed is placed on fixture inner core counterdie 6;
As shown in Figure 9, the one end of multiple folded parts 23 of launching blade is snapped in successively in the spoon connected in star 31 of end circle 3, and make expansion blade surround a cylindrical shape, become blade cylinder 2; Because the folded part 23 of the spoon connected in star 31 pairs of blade cylinders 2 holding circle 3 forms extruding force, thus blade cylinder 2 is made to become an entirety with end circle 3;
Make the Y-shaped outer rim of annular mid-game 1 snap in the annular notches 24 of blade cylinder 2, blade cylinder 2 is fixedly connected with annular mid-game 1;
As shown in Figure 10, the other end circle 3 is connected; Make the opening down of the spoon connected in star 31 of the other end circle 3, the other end of the folded part 23 of blade cylinder 2 is snapped in the spoon connected in star 31 of this other end circle 3;
As shown in figure 11, fixture inner core patrix 7 is placed in is equipped with in the annular mid-game 1 of axle sleeve 5;
As shown in figure 12, adopt roller 8, respectively the spoon connected in star 31 of two end circles 3 is extruded by roll extrusion mode, end circle 3 is fixedly connected with the folded part 23 of blade cylinder 2, realizes blade cylinder 2 and hold being fixedly connected with of circle 3 with two;
As shown in figure 13, remove fixture inner core patrix 7 and fixture inner core counterdie 6, adopt riveter 9, press the projection 11 of annular mid-game 1, make the outer rim of annular mid-game 1 outwards stretch by pressing, now the Y-shaped structure of annular mid-game 1 snaps in the annular notches 24 of blade cylinder 2, as shown in figure 14, by local compression distortion, annular mid-game 1 is integrated with 2 one-tenth, blade cylinder.
