Description

The energy-conservation radiation fan of one-body molded injection moulding magnet ring

Technical field

The utility model relates to the radiation fan that apparatus such as computer is used, and is meant the energy-conservation radiation fan of one-body molded injection moulding magnet ring especially.

Background technique

And after energy-saving fan came out, as shown in Figure 1 and Figure 2, the traditional heat-dissipating fan comprised a pedestal 1 ', as the profile general construction of fan, had determined the size of fan, highly.Oil-impregnated bearing 2 ' is pressed in the newel 11 ' of pedestal 1 ', refills plastic hoop 3 ', puts into Bearing 4 ', again will be by PCB 20 ' combination; And the coil stator 5 ' that last insulating part 51 ', silicon steel sheet 52 ' and following insulating part 53 ' are combined, this coil stator 5 ' is pressed on the newel 11 ' of pedestal 1 ', its front half part work has been finished in the assembling of fan like this, remaining is the assembling of the upright part of flabellum group, and this work wherein will be more loaded down with trivial details.

Again in conjunction with Fig. 3, Fig. 4, be that rubber magnetic stripe 6 ' is pressed into and inserts in the flabellum 81 ' of flabellum 8 ' after magnetite housing 7 ' magnetizes, it is earlier rubber magnetic stripe 6 ' to be pressed into magnetite housing 7 ' the inside according to standard measure, carry out high voltage and magnetize magnetite housing group is upright again, Gauss with the upright empty plastics flabellum 8 ' the inside of containing a core 10 ' that is pressed into of magnet frame group, repairs balance after the assay was approved; Lining weighing apparatus, if shake bad also need carrying out again after balance repairs in addition, it is upright just to obtain complete flabellum group.

So far, put " 0 " shape ring 9 ' again flabellum group vertical cutting be loaded in above-mentioned Bearing 4 ', plastic hoop 3 ', the bearing 2 ', thereby just obtain complete finished product fan.

Yet, the upright need of group between rubber magnetic stripe 6 ', magnetite housing 7 ' and the flabellum 8 ' finished by punch press, stamping jig, high voltage magnetizer, the tool that magnetizes, balancing machine or the like equipment, whole process is artificial processing, and unstability is high, and the heavy industry probability is too big; These group data embody the wretched insufficiency of tradition processing flabellum.And operation is loaded down with trivial details, the manpower waste, and the quality instability, productivity is low.

The model utility content

The utility model is at the existing disappearance of above-mentioned prior art, and main purpose is to provide energy-saving and cost-reducing, cost is low, the energy-conservation radiation fan of steady quality, one-body molded injection moulding magnet ring that efficient is high.

For realizing above-mentioned purpose, the utility model is taked following technological scheme:

The energy-conservation radiation fan of one-body molded injection moulding magnet ring, comprise that a pedestal, a flabellum group are upright and be installed on oil-impregnated bearing, Bearing in the pedestal newel successively, on newel, be arranged with pcb board, coil stator successively, above-mentioned flabellum group is upright to be made of one piece by flabellum, the injection moulding magnet ring that magnetic field is arranged and axle core, wherein this injection moulding magnet ring is located at the leaf body madial wall of flabellum, and the axle core is installed with the leaf body center in flabellum, and is plugged in successively in Bearing, the oil-impregnated bearing.

Above-mentioned injection moulding magnet ring is structure as a whole.

Between bearing, Bearing, has teething ring.

Above-mentioned coil stator is made up of the silicon steel sheet of scratching enameled wire loop with being coated in the upper and lower insulating part upper and lower insulating part.

The utility model compared with prior art, its advantage is as follows: utilize distinctive plastic material, the injection moulding magnet ring that magnetic field is arranged that die sinking is injection molded into rule replaces rubber magnetic stripe and the upright design of magnetite housing group in the prior art, again this injection moulding magnet ring is inserted in the mould of flabellum and to exempt from the one-body molded depanning aftershaping of balancing technique with the flabellum utilization to go out the flabellum group upright, it need not repair balance, and its parts reduce the number of, on technology, do not need above-mentioned many moneys equipment, do not need loaded down with trivial details operation yet, only need by the moulding of injection moulding magnet ring and the moulding of injection moulding magnet ring and flabellum one, only twice molding and forming depanning, can finish the upright assembly working of flabellum group, directly carry out whole fan assembling again, saved a large amount of equipment purchasings, reduced the number of the staff, cost reduces greatly, and flabellum processing all is to finish by the injection machine moulding, and stability is high, need not repair amount of unbalance, manufacturing procedure is simple, time is brief, and personnel reduce, and manpower is fully used, quality has had guarantee, and productivity promotes greatly.
