Description
Technical field
The invention belongs to aluminum alloy outer cover processing technique fields, and in particular to a kind of novel aluminum alloy skin part forming work
The preparation method of dress.
Background technique
Pull-shaped mould is for the Dan Shuan that molded surface product is big, Curvature change is slow on stretching machine, stretching former, smooth in appearance, quality requirement are high
Curvature covering is the important process equipment of forming aircraft covering.Skin part mainly passes through pull-shaped mould during stretch forming
With the relative motion of clamp, pulling force and moment of flexure are applied to plate, extend plate gradually with tooling binding face, and final patch completely
It closes, part required for obtaining.Pull-shaped mode structure is simple, generally there was only punch-pin or cavity plate, and tooling manufacture material is mainly at present
The nonmetallic materials such as metal material and pine, epoxy glue sand.However metal material, because its physical property is poor, surface is also easy to produce
It corrodes, is at high cost, it is easily-deformable after bringing inconvenience, nonmetallic epoxy resin tooling to be used for a long time to product quality, while by
It is affected to factors such as wet weathers, tooling scrappage and overproof rate are high.It is therefore desirable to find it is a kind of have intensity it is high,
Light weight, new material easy to process and with excellent mechanical performances are applied in skin drawing tooling.
To avoid this problem from repeated, the present invention devises a kind of new material skin drawing tool structure to substitute and pass
Commons material manufactures covering tooling, realizes processing high quality skin part.
Summary of the invention
The technical problem to be solved by the present invention is to improve the intensity of skin drawing tooling, it is constant to guarantee that tooling is used for a long time
Shape, tooling surface quality improve.
A kind of preparation method of novel aluminum alloy skin part fixture for forming, steps are as follows:
Tooling is mainly by SAM910 resin matrix 1, SAM900 resin layer 2, hanger rod 3, datum hole 4, foam idiosome 5, perfusion
Hole 6 and overflow hole 7 form；
1) SAM910 resin matrix is made
Milling out matrix outer profile foam idiosome using milling machine number using foamed material is foam outline box, in foam profile
Circular irrigation hole 6 and overflow hole 7 are produced on case；SAM910 resin is poured into the good foam outline box of milling, while being put into and hanging
Stick 3 stops perfusion after overflow hole 7 overflows SAM910 resin, that is, forms SAM910 resin matrix 1；After cured, in SAM910
1 surface preliminary working of resin matrix, criss-cross groove is gone out along tooling areal stretch, for increase SAM900 resin layer 2 with
1 surface binding force of SAM910 resin matrix；
2) surface spreads SAM900 resin layer 2
The SAM900 resin being stirred is taped against step 1) treated 1 surface of SAM910 resin matrix, is guaranteed simultaneously
SAM900 resin layer 2 is the thickness of 30-50mm, waits resin solidification；
3) numerical control mill shape
The tooling that step 2) is cured is placed on work top and carries out numerical control processing, and it is fixed to produce tooling itself by digital-to-analogue first
Position datum hole 4, according to 4 milling tooling shape face of datum hole, precision controlling is between 0.01-0.03mm；
4) outer surface polishes
Numerical control mill rear profile planar defect (stomata, does not solidify epoxy glue at dry sand) etc. is repaired, last silicon carbide paper polishing
To smooth streamline, final pull-shaped mode structure is as shown in Figure 4 in type face.
Novel resin material SAM900 physical property used: appearance is Off-white solid, and density: (23 take the photograph 1.75g/cm3
Family name's degree) mechanical performance: hardness: 85D, bending strength: 52MPa, bending elastic modulus: 5200MPa, compression yield strength:
90MPa, tensile strength: 67MPa.SAM910 physical property: appearance is Off-white solid, and density: (23 is Celsius by 1.1-1.8g/cm3
Degree) mechanical performance: hardness: 82D, bending strength: 80MPa, bending elastic modulus: 2400MPa, compression yield strength: 90MPa,
Tensile strength: 50MPa.
Beneficial effects of the present invention: therefore two kinds of novel resin material SAM910 and SAM900 are applied to by this time invention
The manufacture of skin drawing tooling, to improve the quality and service life of covering tooling.It, will by changing Fixture Design structure
SAM910 resin material spreads 30-50mm thickness SAM900 resin material as tooling matrix, surface.Process SAM910 resin matrix
Before, raw material is stirred to the bubble that generates after mixing between removal different material by de-airing mixer, while guaranteeing that material is mixed
Close uniformity.The raw material mixed is poured in mold idiosome made of foam at room temperature, by spontaneous curing rear surface
It is poured SAM900 resin material again, milling tooling shape face is machined out after the SAM900 resin solidification of surface.After milling
Tooling shape face carries out the smooth streamline polishing of artificial surface, guarantees surface roughness, product is delivered.

Specific embodiment
1) SAM910 matrix manufactures
Mill out matrix outer profile idiosome using milling machine number using foamed material, foam idiosome surface produce circular irrigation hole and
SAM910 liquid is poured into the good foam outline box of milling, while being put into hanger rod by overflow hole, after overflow hole overflows SAM910
Stop perfusion.After cured, SAM910 resin matrix surface preliminary working goes out criss-cross groove along tooling areal stretch, uses
In increasing SAM900 resin and SAM910 resin surface binding force, as shown in Figure 3.
2) surface spreads SAM900 resin
The tooling being surface-treated is sent to the next step, the SAM900 epoxy resin being stirred is taped against SAM910 tree
Rouge matrix surface, while guaranteeing epoxy resin layer thickness, epoxy resin cure is waited, as shown in Figure 1.
3) numerical control mill shape
The tooling being cured is placed on work top and carries out numerical control processing, produces tooling self poisoning benchmark by digital-to-analogue first
Hole, secondly according to datum hole milling tooling shape face, precision controlling is between 0.01-0.03mm, as shown in Figure 2.
4) outer surface polishes
Numerical control mill rear profile planar defect (stomata, does not solidify epoxy glue at dry sand) etc. is repaired, last silicon carbide paper polishing
To smooth streamline, final pull-shaped mode structure is as shown in Figure 4 in type face.
