Description
Technical field
The present invention is on a kind of manufacture method of impeller, especially a kind of manufacture method for being thinned impeller.
Background technology
Existing radiator fan substantially includes a fan frame, a stator, an impeller and a permanent magnet.The stator is arranged at the fan
The gas channel that inframe side is formed;The impeller is rotatably engaged the stator, and the permanent magnet is incorporated into the pre- of the impeller
Position is determined, to form air gap between the stator, so that the stator can drive the impeller to rotate start.
Also, wherein the impeller mainly includes a wheel hub, a magnet sealing piece and a rotating shaft.The wheel hub is provided with several blades, is used to
Driving gas stream is radiated;The magnet sealing piece is arranged on the inside of the wheel hub, and the effect of magnetic is sealed to provide the permanent magnet;The rotating shaft
The wheel hub is then combined, so that the impeller is rotatably engaged the stator.
The manufacture method of existing impeller be generally in advance by the magnet sealing piece and the rotating shaft and meanwhile insert a molding have in, then
The wheel hub with several blades is molded with injection molding method using the mould, the wheel hub one can be coated simultaneously
The magnet sealing piece and the rotating shaft, so complete the impeller be manufactured operation.
However, because electronic product now is universal towards the direction such as miniaturization trend R & D design;Wherein it is installed in each
In formula electronic product, to provide predetermined heat dissipation effect existing radiator fan and its impeller, similarly must matching design be
More compactization, can smoothly be applied to the electronic installation or electronic instrument of miniaturization;The simply manufacture of foregoing existing impeller
The made impeller completed of forming method, is that must be molded in the predetermined position of the wheel hub just like the structure such as rib and crown of roll ring,
One end of the rotating shaft can be coated to firm, and ensure that the rotating shaft will not fall off, therefore, and can not effectively reduce the impeller
Overall axial height, and ejection shaping die must also design complex, and be unfavorable for the impeller being designed as more frivolous
Short and smallization.
Therefore, such as China's application the 201010273456.7th《Fan and its manufacture method》Patent of invention, is to disclose
Another manufacture method of existing impeller.It please coordinate shown in reference picture 1, the manufacture method of another existing impeller is mainly elder generation
One rotating shaft 91 and a metal shell 92 are carried out after laser welding, then the rotating shaft 91 and the metal shell 92 that combination will have been completed
Structure inserts a molding tool(Do not illustrate), and molded using the mould with injection molding method with several blades
931 wheel hub 93, makes the wheel hub 93 only integrally coat the metal shell 92, so complete the impeller 9 be manufactured operation.
Whereby, the made impeller 9 completed of the manufacture method of another existing impeller, its wheel hub 93 and the rotating shaft 91 1
The binding site at end need not then form such as rib or crown of roll ring structure, and the also design of the relative simplicity mould, and can
Convenient electronic installation or electronic instrument applied to miniaturization.
However, the problem of manufacture method of another existing impeller still has as described below.Wherein when the rotating shaft 91 with
, so can be smoothly complete when the metal shell 92 carries out laser welding, it is necessary to the outer surface of the rotating shaft 91 is positioned using tool
Into the rotating shaft 91 and the combination of the metal shell 92, and ensure the centralized positioning precision of the rotating shaft 91;Combination ought have been completed again
The rotating shaft 91 and the structure of metal shell 92 be intended to insert the mould to mold during the wheel hub 93, then must equally utilize
The rotating shaft 91 is positioned in the mould;In other words, the manufacture method of the existing impeller at least this turn of necessary resetting
Axle 91 is twice, it is not only possible to causes the outer surface of the rotating shaft 91 to repeat scratch and is damaged, it is easier to is positioned at this in the rotating shaft 91
During mould, cause the centralized positioning precision of the rotating shaft 91 to deviate again, the impeller 9 is applied to radiator fan
When, the shortcomings such as Rotation Noise and reduction motor life are easily produced, therefore, offer one kind is be provided and is preferably thinned impeller
Manufacture method.
The content of the invention
The main object of the present invention is for slim the problem of improveing the manufacture method of foregoing each existing impeller there is provided one kind
Change the manufacture method of impeller, the manufacture method repeats scratch without resetting rotating shaft with the outer surface for being prevented effectively from rotating shaft
Impaired situation.
An of the invention purpose is to provide a kind of manufacture method of impeller, turn of the made impeller completed of the manufacture method
Axle is effectively reduced centralized positioning precision skew problem, to provide good running effect.
To reach aforementioned invention purpose, the present invention with technological means include:
