Abstract
The utility model discloses a novel structure fan propeller is used in to on the local radiating radiator fan such as on -vehicle integrated equipment, office equipment, financial equipment, communications network equipment, domestic appliance for on the fan motor to improvement production efficiency, reduction material cost, environmental protection, increase fan propeller life -span are the mesh. This structure is compared with ordinary resin impeller, has light in weight, stability is high, shock resistance is good, balanced characteristic is good, is suitable for characteristics such as making ultra -thin, miniature fan to make the fan motor obtain very big improvement in the aspect of quality, stability. It is had portable instrument, the equipment of strict demand to provide excellent heat dissipation scheme to the space to be suitable for the characteristics ultra -thin, miniature fan of doing.
Description
Technical field
The utility model relates to a kind of fan propeller, is used on the radiation fan into local heat radiations such as vehicle-mounted integrated equipment, office equipment, finance device, communication network device, household electric appliance.
Background technique
Existing fan propeller, adopt plastic pellet, by the method processing fan propeller of injection machine molding and forming, in advance impeller shaft and yoke plate are fixed on injection mould, molding and forming blast fan again, finally in magnet steel press-in impeller, although existing technology is widely used, there is a lot of shortcoming:
1, manufacturing efficiency is low,
2, cost of material is high,
3, environmetal impact is large, particularly large especially to human injury at injection workshop,
4, plastic pellet is at high temperature very serious to the damage of mould, adds the frequency of maintenance of mould, shortens die life,
5, the waste material formed out, the recycling recovery rate is low.Difficulty is brought to business processes,
6, the impeller of plastic article is easily aging in atmosphere, affects motor life,
In sum: occur that a kind of manufacturing efficiency is high, the cost of material is low, environmental protection, increase fan life the blast fan of neotectonics be necessary.And the present invention just by cost of material of enhancing productivity, reduce, protection of the environment, for the purpose of the increase fan propeller life-span.
Summary of the invention
The utility model is solve the indeterminable problems such as prior art manufacturing efficiency is low, cost of material is high, environmental pollution, provides a kind of and enhance productivity, reduce the fan propeller of cost of material, protection of the environment, the novel structure in increase blast fan life-span
The utility model, for above technical problem, is mainly undertaken solving by following proposal: the rotor of novel structure comprises impeller, axle, fixture, magnet steel.By tool, make impeller, axle, fixture concentric, and the method being crimped by punch press or weld, axle, fixture, impeller are firmly combined.By glue, magnet steel is bonded at impeller surface.Complete the fan propeller of a novel structure like this.The fan propeller of this neotectonics has following advantage:
1, the cost of material is low,
2, manufacturing efficiency is high,
3, environmental pollution is without (except noise), waste material can 100% reclaim,
4, the life-span is long, not easily aging.
5. the fan propeller of novel structure has following technical characterstic:
1. impeller adopts the sheet metal of magnetic conduction, processes by stamping forming method.Go out the shape of impeller, the shape of every sheet a slice is the same, quality is the same, and make impeller have good equilibrium response, fan motor is operated stably, metallic material has good shock resistance.
2. rotor adopts flat magnet steel and the thin slice of metal.Motor is done miniature, thinner, gentlier become possibility.
3. flat magnet, magnetizes in surface.By the rational design of fan motor.Have employed axial magnetic field structural design, energy conversion efficiency is very high to be increased with torque volume ratio, improves the efficiency of fan motor greatly, makes motor have stable service performance simultaneously.
Accompanying drawing illustrates:
Fig. 1 is the organigram of existing fan propeller, by 1, impeller, and 2, axle, 3, magnet steel, 4, magnet steel yoke plate composition
Fig. 2 is the organigram of model utility fan propeller, by 1, impeller, and 2, axle, 3, fixture, 4, magnet steel composition
Fig. 3 is the upper tool of impeller crimping, and at one end has the shape of plum blossom print, and its effect is fixture 3, axle 2 and impeller are firmly crimped together.
Embodiment
Below by embodiment, and by reference to the accompanying drawings the technical solution of the utility model is described in further detail.
Embodiment 1: the fan propeller of the novel structure of the present embodiment, and the rotor of structure novel is as shown in Figure 2 made up of impeller 1, axle 2, fixture 3, magnet steel 4.The newel that fixture 3 is placed on tool is located, the center hole of impeller 1 is put on fixture 3 step surface, the bottom surface of impeller 1 is parallel with fixture 3 bottom surface, and axle 2 is placed in the center hole of the upper tool of the crimping of impeller shown in Fig. 3, impeller 1, axle 2, fixture 3 require with one heart, with punch press, axle 2 is pressed in the center hole of fixture 3, fixture 3 step surface is subject to punching press generation distortion and stays next plum blossom to print, fixture 3 step surface external diameter is increased, with the center hole interference fit of impeller 1, fixture 3, axle 2 and impeller 1 are firmly crimped together; And by glue, magnet steel 4 is bonded at impeller surface, complete the fan propeller of a novel structure like this.
The shape of the upper tool plum blossom print of embodiment 1 middle period wheel crimping is a part for the utility model right.
The plum blossom impression shape of the upper tool one end of impeller crimping, its effect is: fixture 3, axle 2 and impeller are firmly crimped together.Because offset ring concavo-convex is uneven, stay next plum blossom to print when fixture 3 step surface is subject to punching press generation distortion, fixture 3 step surface external diameter is increased, fixture 3, axle 2 and impeller 1 are firmly crimped together.
Embodiment 2: the fan propeller of the novel structure of the present embodiment, and the rotor of structure novel as shown in Figure 2 comprises impeller 1, axle 2, fixture 3, magnet steel 4.The mode embodiment 1 that axle 2 is pressed into fixture 3 is identical.The mode of the employing welding of the center hole of fixture 3 step and impeller 1 is fixed together.Axle 2, fixture 3, impeller 1 is so just made firmly to combine.The means of fixation of magnet steel 4 is identical with embodiment 1.The same like this fan propeller that can complete a neotectonics.
Specific embodiment described herein is only to the utility model explanation for example.The utility model person of ordinary skill in the field can to described specific embodiment, makes various amendment or supplements or adopt similar mode to substitute, but can't depart from the utility model or surmount the scope that appended claims defines.
Although more employ impeller herein, axle, magnet steel, the terms such as magnet steel yoke plate, fixture, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily.
