Abstract
The invention belongs to technique for aircraft composite manufacture field, it is related to a kind of solution tubular low-angle composite material parts release method long.The tubular composite material parts release method is when tubular composite is molded, symmetrical paving forms the boss of one with part at the outer side center line of part mouthful frame portion position, jack is fixed, and cause that mandril of lifting jack is withstood on boss as stress point, exerted a force with jack and part is axially promoted along shaping mould tire, complete part removal.The present invention can solve tubular low-angle composite material parts release problems long, it is ensured that not injuring part in knockout course, and easy to implement, wide adaptability, low cost, with larger actual application value.
Description
Technical field
The invention belongs to technique for aircraft composite manufacture field, it is related to a kind of solution tubular composite material parts release method.
Background technology
After composite product is made on the mould, although molding die surface is bright and clean, coating or paving are de- again
Mould material, but composite product is taken off from mould, all it is not lead-pipe cinch feelings.Practice have shown that, composite wood
The material products demoulding has to overcome adhesion and absorption affinity.Wherein adhesion be resin matrix with mould binding face curing molding after
Produce, absorption affinity is that, due to the intimate vacuum state in interface when prepreg is plated in mould, the absorption for producing at atmosheric pressure is made
Firmly.As can be seen here, release method actually how using external force method.
It is main in the development of current composite to use changable modulus method and mechanical stripping method.Changable modulus method is typically applicable
In the more easy composite product of profile, its adhesion and absorption affinity are also smaller, are typically first tapped with wooden mallet or rubber hammer
Mould, composite product part and mould are made by tapping the vibrations for producing.Typically we can be from the sound in percussion
Sound judges whether product disengages with mould, real if sound and do not separated if weight, such as sound it is empty and it is light if to have disengaged.Taken off at one
Beating point is gradually extended after opening again, demoulding scope is gradually expanded, finally prized with instrument at one end, you can try composite wood
Material is taken off from mould.Mechanical stripping generally pulls mould with the tractive force of the plant equipment such as lead screw device, hoist engine or crane
Tool, is allowed to complete stripping process.
During composite product development and production, through being commonly encountered the release method with routine, such as compressed air is pneumatic
Demoulding method, plus the conventional method such as wedge method, mechanical stripping method, temperature differential method, douche, stripping method be difficult to the problem that disengages product.
Especially for tubular composite material parts, because size is long, angle is small, and termination is difficult to without stress point, conventional release method
Not influenceing, on the premise of damaged composite material part, stripping process is smoothly completed, it is impossible to which the demoulding for meeting such part will
Ask.
The content of the invention
The purpose of the present invention is：There is provided one kind can smoothly complete size long, low-angle under the premise of part is avoided damage to
The tubular composite material parts demoulding method.
The technical scheme is that：A kind of tubular composite material parts release method, it is molded in tubular composite
When, symmetrical paving forms the boss of one with part at Central of the parts line on the outside of part mouthful frame portion position, and jack is fixed,
And cause that mandril of lifting jack is withstood on boss as stress point, exerted a force with jack and part axially promoted along shaping mould tire,
Complete part removal.
The jack being fixed on shaping mould tire ring flange is symmetrical two, is withstood on by various push rods symmetrically arranged
On boss.
The jack is fixed at the termination bulge-structure of shaping mould tire.
The termination bulge-structure of the shaping mould tire is ring flange.
The boss of piece surface is cut after part removal.
It is an advantage of the invention that：Compared with prior art, to solve tubular low-angle composite material parts long de- for the present invention
Modulus problem, it is ensured that not injuring part in knockout course, and easy to implement, efficiency high, low cost, wide adaptability, can promote use
In the demoulding treatment of similar tube shape component, with larger actual application value.
Brief description of the drawings
Fig. 1 is the part and mould tire one schematic diagram that the present invention treats the demoulding；
Fig. 2 is mould tire main body schematic diagram；
Fig. 3 is part schematic diagram；
Fig. 4 is tubular composite material parts demoulding schematic diagram of the present invention；
Wherein, 1- parts, 2- mould tires main body, 3- ring flanges, 4- jack, 5- push rods, 6- bosses.
Specific embodiment
The present invention is described in further details below.
1 is referred to, it is the part and mould tire one schematic diagram that the present invention treats the demoulding.In figure, part is socketed in outside mould tire.
Fig. 2 is referred to, it is mould tire main body schematic diagram.The mould tire is metal material, has bulge-structure in its end,
The bulge-structure is ring flange, conveniently stripped for support jack.
Fig. 3 is referred to, it is part schematic diagram.Two bosses of the symmetrical paving in mouth frame portion position outside, the boss
It is made of one piece when being manufactured for the tubular composite, is symmetrically distributed along shaft parts center, is provided during for the demoulding and put forth effort branch
Support point.
Fig. 4 is referred to, it is tubular composite material parts demoulding schematic diagram of the present invention.Two identical jack are provided,
Jack one end is fixed on mould tire ring flange, and causes that two mandril of lifting jack withstand on two bosses respectively, with two
Boss is exerted a force with jack and part is axially promoted along shaping mould tire as impetus, completes part removal.The demoulding is completed
Afterwards, final part processing is completed by cutting composite boss, whole process will not in itself cause to damage to part, effective guarantee
Quality during part removal.
Simple structure of the present invention, it is easy to operate, only need boss integrally formed on tubular composite in advance, you can pole
The earth facilitates the follow-up demoulding to work.And jack of the present invention it is not absolutely required to be fixed on mould tire ring flange, it is also possible to straight
Connect and be fixed on elsewhere, such as ground or wall stationary plane, as long as push rod withstands boss, can still complete demoulding work.Cause
This release method of the present invention is simple, practical, and goes for that various sizes are long, the small tube shape component of angle or cylinder part
The demoulding, with larger promotional value and practical value.
