Abstract
The utility model belongs to Composites Molding Techniques, and in particular to a kind of multiple material forming parts foamed aluminium frock.The multiple material forming parts foamed aluminium frock of the utility model can process epoxy plastics type face by foam aluminium chassis and high temperature resistant and form, wherein, the foam aluminium chassis are formed with a support type face, epoxy plastics type face is laid on the support type face of foam aluminium chassis, and the high temperature can be processed on epoxy plastics type face and be painted with sealant.The multiple material forming parts foamed aluminium frock high temperature resistant of the utility model is unlikely to deform, and good airproof performance is simple in construction, easy to make, and cost is relatively low, has larger actual application value.
Description
Technical field
The utility model belongs to Composites Molding Techniques, and in particular to a kind of multiple material forming parts foamed aluminium frock.
Background technology
It is existing during the thermoforming frock of conventional non-metal workpiece (antenna house, radome, radome fairing, interior trim wallboard) is developed
There is technology compound to make typically using metal casting structure and expoxy glass steel construction according to the requirement of thermoforming frock
Material parts forming frock.This kind of frock has very high requirement to theoretical profile, surface quality, air-tightness, heat endurance, main
Including：Thermoforming frock type face is not allow for the manufacturing defect such as not fairing, depression；Thermoforming frock is usually in furnace temperature 135
DEG C -180 DEG C, reuse in vacuum 0.08-0.092MPa environment, it is desirable to which frock is reused constant in such circumstances
Shape, cracking, delamination；Thermoforming frock does not allow phenomena such as gas leakage be present in use.
The frock of above two different materials and structure type respectively has advantage and disadvantage, can still meet composite wood over a period to come
Expect the demand of part production.But as product batch is gradually increased, product technology requires to improve constantly, and product manufacture is not
It is disconnected to improve, and the continuous renewal replacement of material and facility, existing metal casting structure and fiber glass epoxy structure composite material
Material forming parts frock is difficult to the production requirement for meeting trim part, is mainly shown as that tooling production efficiency is low, manufacturing cost
It is serious that high and later stage frock deforms big, bulge, cracking, gas leak phenomenon.
Utility model content
Purpose of utility model：It is simple in construction, easily manufactured to provide one kind, and on-deformable multiple material forming parts foamed aluminium
Frock.
Technical solutions of the utility model：Multiple material forming parts foamed aluminium frock, it can be added by foam aluminium chassis and high temperature resistant
Work epoxy plastics type face forms, wherein, the foam aluminium chassis are laid on foam formed with a support type face, epoxy plastics type face
On the support type face of aluminium chassis.
The thickness for overlapping each foamed aluminium board for forming the foam aluminium chassis is identical.
The wall thickness of the foam aluminium chassis is 20~30mm.
The epoxy plastics type face thickness is in 15~20mm.
The foam aluminium chassis support type face is plane or arc surface or hyperboloid or parabola.
The high temperature can be processed on epoxy plastics type face and be painted with sealant.
The advantages of the utility model and effect：Compared with prior art, the multiple material forming parts foamed aluminium work of the utility model
Dress solves big traditional glass steel frock deformation, bulge, cracking and leakage using foamed aluminium, the multiple material forming frock of high-temp epoxy material
Gas phenomenon, the quality of the forming frock is improved, ensure the stability of product quality, shorten the product trial assembly cycle.Meanwhile cancel
Transition tool (often covering multiple material frock can reduce by 2 sets of transition tools), reduces the cost about 50% of frock manufacture, reduces worker
The harm of labor intensity and epoxy resin to worker's health, there is larger actual application value.
Brief description of the drawings
Fig. 1 is the multiple material forming parts foamed aluminium frock type face schematic diagram of the utility model；
Fig. 2 is the multiple material forming parts foamed aluminium frock block schematic illustration of the utility model,
Wherein 1- types surface layer, 2- foam aluminium chassis.
Embodiment
The utility model is described in further detail below.
Please refer to Fig. 1 and Fig. 2, the multiple material forming parts foamed aluminium frock of the utility model includes foam aluminium chassis and resistance to
High temperature can process epoxy plastics type surface layer.Wherein, the foam aluminium chassis are 500kg/m from density3, thickness 20-30mm's
Foamed aluminium board, formed by being glued overlap joint.The foam aluminium chassis overlapped are formed with a support type face, the support type face root
Can be plane or arc surface or hyperboloid or parabola according to composite material parts forming requirements.
The high temperature resistant can process epoxy plastics type surface layer can process plastics B4000A/B using thickness about 20mm high temperature,
And the high temperature can be processed on epoxy plastics type face and be painted with sealant, sealant is FREKOTE B-15 in the utility model,
Other refractory seals agent are also an option that according to being actually needed.
The multiple material forming parts foamed aluminium frock making process of the utility model is as follows：Foamed aluminium is first determined according to frock size
Matrix blank dimension.Then it is 500kg/m by density3, 20~30mm of thickness foamed aluminium board machining after paste be framework
Place foam aluminium profiles face gap is consolidated with Araldite LY1564 normal temperature around basal body structure, matrix inoperative side and lift hand hole
Change the greasy reality of fire resistant epoxy superficial layer glue, repairing polishes smooth.Frock type surface layer uses and uniformly presses B4000A:B4000B=
2.5kg:The high temperature resistant that 2.5kg ratios are prepared can process resin paving, thickness control about δ 15mm.Last normal temperature cure 24H is laggard
Stove is classified heating cure, using numerical control device processing type face and delineation part edge line after solidification, to work after die numerical control processing
Make type face and carry out sanding and polishing, and brush seals agent FREKOTE B-15, the solidification of frock secondary heating, complete the utility model and answer
Material forming parts foamed aluminium frock making.Obtained frock high temperature resistant is unlikely to deform, and good airproof performance is simple in construction, making side
Just, cost is relatively low, has larger actual application value.
