Specific implementation mode
In conjunction with attached drawing, for this water pump vane for being rotatably mounted in the pump chamber of water pump, structure includes circular ontology 1,
Wheel hub 2 is equipped at the axial location of ontology 1, rotating hub is used for and the power output shaft of motor is connected, power supply machine impeller
It is rotated in pump chamber.The peripheral region of ontology 1 is formed with sharp edge, and sharp edge is that the thickness of ontology 1 in the axial direction becomes smaller from opposite sides
And it is formed.Several blades 3 are evenly equipped at sharp edge position, these blades 3 are perpendicular to ontology 1, width and the ontology 1 of blade 3
Inboard portion thickness is generally equal.Due to there is the presence of sharp edge so that after blade 3 is arranged on ontology 1, blade 3 has opposite
The larger promotion effective area to water.
Ontology 1 is split structure, is made of together several component assemblings.These components have cover board 11, leaf
Piece 3 and wheel hub 2, they are generally stainless steel, and cover board 11 and blade 3 are stamping parts, and wheel hub 2 is cast member.Plank rushes
After pressure processing forms cover board 11 so that 11 periphery inboard portion of cover board is arched upward towards axial side, and to be formed on cover board 11
Sunk structure as one kind.In one impeller, including two cover boards 11 that are coaxially fixed together, two cover boards 11 snap together,
And two cover boards, 11 periphery inboard portion is arched upward respectively towards opposite sides protrusion.The outer surface of two cover boards 11 constitutes ontology
1 outer profile, the periphery of two cover boards 11 and periphery inboard portion form the sharp edge structure on ontology 1.Plate stamping processes shape
When at blade 3, socket 31 can be formed on blade 3, the sharp edge of ontology 1 is plugged in socket 31, and blade 3 is connected to two lids simultaneously
On plate 11, blade 3 grips the periphery of two cover boards 11 from the sharp edge position of ontology 1.
It realizes the axial restraint to two cover boards 11, is realized generally by the mode of riveting rivet.But due to lid
Corresponding site itself on plate 11 arches upward, this influences whether two cover board of rivet pair, 11 fixed fastness.Therefore, in cover board 11
Concave ring 12 outstanding can be formed in process, the concave ring 12 on two cover boards 11 is arranged symmetrically in relation to each other.Concave ring 12 is located at ontology 1
Between upper sharp edge and wheel hub 2, the concave ring 12 on two cover boards 11 protrudes toward each other, and the bottom surface of concave ring 12 is mutually close, passes through rivet
When from concave ring 12 and two cover boards, 11 rivet clasp together, the bottom surface of the concave ring 12 on two cover boards 11 fits together.
In this split type ontology 1, the inner hollow of sharp edge is formed with annular inside sharp edge between concave ring 12
Chamber is equipped with the elastomer 4 of circular ring shape in annular chamber.Elastomer 4 matches with annular chamber, outer surface and the annular of elastomer 4
The internal face of chamber fits.Elastomer 4 is usually made of the nonmetallic materials such as rubber, plastics.If being formed on cover board 11
Dry penetrating card hole 14 corresponds in the peripheral region of cover board 11 and is equipped with opening 13 at 3 position of blade.Card hole 14 is used for and blade 3
On 32 phase of clamp be connected together, and realize being connected and fixed between blade 3 and ontology 1.Socket 31 on blade 3 is V-shaped,
Clamp 32 is respectively formed at the opposite sides of socket 31, and after blade 3 is connected in from the sharp edge of ontology 1 on ontology 1, clamp 32 is saturating
Crossing card hole 14 can be in contact with elastomer 4, and blade 3 is simultaneously in opening 13.
Integrally formed with export-oriented bulge loop 21 on the peripheral surface of wheel hub 2, export-oriented bulge loop 21 is by two cover boards 11 from opposite sides pressure
It is connected together.It is also set up on export-oriented bulge loop 21 there are four notch 22, these notches 22 are supplied for two cover boards 11 that are connected and fixed
Rivet passes through.Under normal conditions, export-oriented bulge loop 21 is located at the inner end of wheel hub 2, the inner face of a cover board 11 and wheel hub 2 therein
It fits, and so that 2 direct top pressure of wheel hub is on a cover board 11, the contact area between wheel hub 2 and the cover board 11 is relatively large,
Between wheel hub 2 and ontology 1 to couple fastness good.
The preparation method of this water pump vane is relatively simple, and key step includes：Cover board 11 is processed, blade 3, shape are processed
At ontology 1 and assembly blade 3.
Cover board 11 is to process formation by way of punching press by stainless steel materials, and cover board 11 is rounded, passes through mold
Setting so that during punch forming, the inboard portion of 11 periphery of cover board is arched upward to side, in the peripheral region shape of cover board 11
At there is several uniformly distributed openings 13.Blade 3 is processed by impact style, the socket 31 of V-arrangement is formed on blade 3, is being inserted
The opposite sides at 31 13 ends of opening of mouth are respectively formed with clamp 32.
Two panels cover board 11 is coaxially snapped together, the periphery of two panels cover board 11 is bonded and forms sharp edge, on two cover boards 11
13 positions that are open are overlapped one by one, and the sharp edge structure size is as shown in Fig. 2, the small inside in periphery is big.The export-oriented bulge loop 21 on wheel hub 2
It is connected between two panels cover board 11, two panels cover board 11 is riveted together in the axial direction by rivet, the week of two cover boards 11 at this time
Edge is close together.Sharp edge inner hollow, and an annular chamber can be formed, when forming ontology 1 two cover boards 11 and a circular ring shape
Elastomer 4 it is axially stacked together, elastomer 4 matches with annular chamber, the outer surface of elastomer 4 and the inner surface of annular chamber
It fits.
Blade 3 is plugged into along the radial direction of ontology 1 on ontology 1 using fixture so that blade 3 is along the radial setting of ontology 1, often
The a piece of blade 3 of assembly, socket 31 are socketed at sharp edge position in a opening 13.After blade 3 assembles, using pressing element from originally
The axial opposite sides of body 1 carries out crimping shaping to blade 3 and so that the clamp 32 on blade 3 penetrates card hole 14, and top pressure exists
On the outer surface of elastomer 4.
