Degree is deteriorated, or even is difficult to.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of method and devices for processing Low rigidity thin wall vane.
To reach above-mentioned purpose, technical scheme is as follows, a kind of device for processing Low rigidity thin wall vane, special
Sign is, mainly includes medium 7, mould 8, cooling system and heating system；The medium 7 is containing being under iron powder and room temperature
The aqueous solution of existing liquid, is placed between blade and mould；The cooling system is arranged around mould, including liquid nitrogen container 1, pressure
Adjuster 2, flowmeter 3, flexible hose 4, nozzle 5；The heating system is arranged around mould, including electromagnetic coil 9, electric wire
10, support frame 11, controller 12, wherein electromagnetic coil 9 and support frame 11 are placed on 8 lower section of mould.
The mould upper surface and blade surface adhered shape as a preferred technical solution, mould upper surface exist very
The microcosmic texture of more pits and groove.
A method of processing Low rigidity thin wall vane, which comprises the following steps:
Mould 8 and the painting of 6 contact surface of blade are spread one layer of aqueous solution containing iron powder by step 1, and blade 6 to be processed is placed on
On mould 8；
Step 2 opens liquid nitrogen container 1, and liquid nitrogen is injected on blade 6 through pressure regulator 2, flowmeter 3, flexible hose 4, nozzle 5,
Cool down, and then make 7 cooled and solidified of medium, blade 6 is fixed on mould 8, positioning and fixing are played the role of；
Step 3, starting lathe, import numerically-controlled machine tool for the program editted before, start the upper table for operating milling cutter processing blade
Face.After the process finishing of blade upper surface, milling cutter is removed；
Step 4 is powered to the electromagnetic coil 9 below mould, and coil generates magnetic field after being powered, and the blade 6 in magnetic field can be sent out
Heat can be such that medium comparatively fast melts, at this moment can power off to electromagnetic coil due to there is the reason of iron powder in medium 7, will be machined
Blade take out.
The present invention have it is following the utility model has the advantages that
The method and device of a kind of Low rigidity thin wall vane provided by the invention, since blade is bonded with mould surface, by blade
When being fixed on mould with medium, there is support to the every bit of blade on mould, in processing, can reduce cutting force to leaf
The influence of piece guarantees processing quality.
Detailed description of the invention
Illustrate the embodiment of the present invention or technical solution in the prior art in order to clearer, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described.
Fig. 1 is the structural schematic diagram of present invention processing Low rigidity thin wall vane device；
Fig. 2 is the microcosmic texture schematic diagram in mould upper surface；
Fig. 3 is schematic diagram of cooling system structure in the present invention；
Fig. 4 is heating system schematic diagram in the present invention；
In figure: 1 liquid nitrogen container, 2 pressure regulators, 3 flowmeters, 4 flexible hoses, 5 nozzles, 6 blades, 7 media, 8 moulds, 9 electromagnetism

Specific embodiment
Below in conjunction with the attached drawing in the present invention, technical solution in the embodiment of the present invention carry out it is clear, completely retouch
It states and discusses, it is clear that as described herein is only a part of example of the invention, is not whole examples, is based on this hair
Embodiment in bright, those of ordinary skill in the art's every other reality obtained without making creative work
Example is applied, protection scope of the present invention is belonged to.
Referring to Fig.2, Fig. 2 is the surface microscopic texture schematic diagram of mould in Fig. 1.
8 upper surface shape of mould is bonded with 6 surface shape of blade, exist many small pits or the surface of groove knit
Structure.Due to adhered shape, when blade 6 is placed on mould 8, mould 8 plays positioning and supporting role to blade 6.When medium 7
Blade 6 can be fixed on mould 8 when solidification.
It is cooling system schematic diagram in Fig. 1 refering to Fig. 3, Fig. 3.
Liquid nitrogen passes through pressure controller 2, flowmeter 3, flexible hose 4 by liquid nitrogen container 1, is finally injected in blade 6 by nozzle 5
On, since liquid nitrogen gasification takes away certain heat, ambient temperature can be made to reduce, the phenomenon that medium 7 can generate solidification, at this time
Blade 6 is fixed on mould 8.In 6 process of blade, sustained firing liquid nitrogen is needed, to prevent medium 7 from melting.
It is heating system schematic diagram in Fig. 1 refering to Fig. 4, Fig. 4.
After 6 surface process finishing of blade, it is powered to electromagnetic coil, alternating current is converted into direct current by controller 12,
Direct current makes 9 surrounding of electromagnetic coil generate magnetic field by electromagnetic coil 9, and blade 6 and medium 7, which are in magnetic field, can generate vortex, into
And generate heat, so that medium 7 is become liquid from solid-state.
In summary as it can be seen that Low rigidity thin wall vane is fixed on shape patch by using the method that liquid solidifies by the present invention
On the mould of conjunction, so that blade is unlikely to deform in process, after process finishing, melting media is made in the short period, it will
Blade takes out.
