Abstract
The release method of the T-shaped part of large-sized composite material belongs to manufacture technology of composite material field, the release method of the T-shaped part of large-sized composite material, it is characterised in that：Comprise the following steps, 1. the T-shaped part of material to be composite cures completion, the encapsulating material for removing surface after, hydraulic device 3. back oil cavity pressure is adjusted, hydraulic device is 3. contracted to certain length, and then be 2. 3. closely joined together metal core die with hydraulic device by fastener.Then, hydraulic device 3. oil inlet cavity pressure is slowly adjusted, the mechanical removal of metal core die 2. is easily realized by the hydraulic device active force of metal core die 2. that acts on that 3. stretching process produces.Traditional stripping means of damage problem invention not only avoids to(for) the T-shaped part of composite material, and the workload of demoulding personnel is simplified, lift demoulding efficiency.
Description
Technical field
The invention belongs to manufacture technology of composite material field, more particularly, to a kind of the de- of the T-shaped part of large-sized composite material
Mould method.
Background technology
T-shaped stringer because its own rigidity it is big the features such as, be widely used in such as Boeing B787, Air Passenger A350XWB and domestic
The main force support structures such as the fuselage and wing wallboard of C919 strengthen.For the design feature of the part, the Chang Xuan in its manufacturing process
Type metal hard die is taken as core, to ensure the axis precision of T-shaped part and surface quality.However, due to composite wood and metal frock
Between coefficient of thermal expansion there are significant difference, the internal stress produced after curing can cause metal core die to be difficult to remove from part,
Traditional method is made between core and part to be tapped using metal tools to metal core die with will pass through the effect of physical force
Generation separation, sliding produce gap, and then realize that the effective of core removes still, inevitable using this release method
Can be tapped due to physics, which causes product that layering etc. occurs, destroys, and influences product quality, and metal core die can be caused to deform
Even destroy, seriously affect product manufacturing progress.
The content of the invention
In view of the deficienciess of the prior art, the technical problems to be solved by the invention are to provide a kind of efficient and demould
The release method of the T-shaped part of large-sized composite material of product quality is not influenced.
The present invention is adopted the following technical scheme that to complete：The release method of the T-shaped part of large-sized composite material, its feature
It is：Comprise the following steps, 1. the T-shaped part of material to be composite cures completion, the encapsulating material for removing surface after, adjust hydraulic device
3. back oil cavity pressure, makes hydraulic device 3. be contracted to certain length, and then is 2. filled metal core die with hydraulic pressure by fastener
Put and be 3. closely joined together.
Then, hydraulic device 3. oil inlet cavity pressure is slowly adjusted, passes through hydraulic device 3. acting on of producing of stretching process
The active force of metal core die 2. easily realizes the mechanical removal of metal core die 2..
The metal core die carries screw hole, can be closely joined together by fastener and hydraulic device, connection
Mode is fastener to be connected with the screw hole of metal core die by bolt, also, tie point position is in metal core die centre bit
Put, and two tie points are on same axis, with ensure tension force caused by hydraulic device stretching, extension can with useful effect in
Metal core die.
The hydraulic device should be at contraction-like when the T-shaped part after curing completely of composite material is connected with metal core die
State, and should be at extended configuration during demoulding.
The present invention has following advantage compared to traditional release method of the T-shaped part of composite material, make use of hydraulic device just
In realizing physics stretching, extension and contraction state and easy to produce huge mechanical force, can by adjusting hydraulic device oil back chamber with
The pressure of oil suction chamber, to realize the subtractive process of the connection of metal core die and hydraulic device and metal core die, not only avoid
Traditional stripping means and simplify the workload of demoulding personnel, lifting demoulding effect for the damage problem of the T-shaped part of composite material
Rate.
Brief description of the drawings
Fig. 1 is the demolding structure schematic diagram of the present invention.
Fig. 2 is the demolding structure side view of the present invention.
In figure, 1. T-shaped part；2. metal core die；3. hydraulic device；4. bolt；5. connecting plate.
Embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
With reference to the accompanying drawings shown in 1-2, the release method of the T-shaped part of large-sized composite material, it is characterised in that：Including following step
Suddenly, after 1. the T-shaped part of material to be composite cures completion, the encapsulating material for removing surface, hydraulic device 3. back oil cavity pressure is adjusted, is made
3. hydraulic device is contracted to certain length, and then by fastener 2. with hydraulic device 3. metal core die is close-coupled at one
Rise；The fastener is connecting plate.Then, hydraulic device 3. oil inlet cavity pressure is slowly adjusted, is 3. extended across by hydraulic device
The active force of metal core die 2. that acts on that journey produces easily realizes the mechanical removal of metal core die 2..
The metal core die carries screw hole, can be closely joined together by fastener and hydraulic device, connection
Mode is fastener to be connected with the screw hole of metal core die by bolt, also, tie point position is in metal core die centre bit
Put, and two tie points are on same axis, with ensure tension force caused by hydraulic device stretching, extension can with useful effect in
Metal core die.
The hydraulic device should be at contraction-like when the T-shaped part after curing completely of composite material is connected with metal core die
State, and should be at extended configuration during demoulding.
The present invention has following advantage compared to traditional release method of the T-shaped part of composite material, make use of hydraulic device just
In realizing physics stretching, extension and contraction state and easy to produce huge mechanical force, can by adjusting hydraulic device oil back chamber with
The pressure of oil suction chamber, to realize the subtractive process of the connection of metal core die and hydraulic device and metal core die, not only avoid
Traditional stripping means and simplify the workload of demoulding personnel, lifting demoulding effect for the damage problem of the T-shaped part of composite material
Rate.
Preferred embodiment of the invention described in detail above.It should be appreciated that those of ordinary skill in the art without
Need creative work to conceive according to the present invention and make many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be in the protection domain being defined in the patent claims.
