Description
Technical field
The invention belongs to technique for aircraft composite manufacturing fields, are related to a kind of solution tubular composite material parts release method.
Background technique
After making composite product on molding die, although molding die surface is bright and clean, and coat or paving is de-
Mould material, but composite product is taken off from mold, it is all not lead-pipe cinch feelings.Practice have shown that composite wood
Material products demoulding has to overcome adhesion strength and adsorption capacity.After wherein adhesion strength is resin matrix and mold binding face curing molding
It generates, adsorption capacity is the intimate vacuum state in interface when being plated in mold due to prepreg, and the absorption generated at atmosheric pressure is made
Firmly.It can be seen that the method how release method actually utilizes external force.
Changable modulus method and mechanical stripping method are mainly used in the development of current composite material.Changable modulus method is generally applicable in
In the more easy composite product of shape, adhesion strength and adsorption capacity are also smaller, are usually first tapped with wooden mallet or rubber hammer
Mold makes composite product part and mould by tapping the vibration generated.Generally we can be from the sound in percussion
Sound judges whether product disengages with mold, real if sound and do not separate if weight, as sound is empty and light to have disengaged.It is taken off at one
Beating point is gradually extended after opening again, demoulding range is gradually expanded, is finally agitated, can be tried composite wood with tool at one end
Material is taken off from mold.Mechanical stripping usually pulls mould with the tractive force of the mechanical equipments 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, as compressed air is pneumatic
The conventional methods such as demoulding method plus wedge method, mechanical stripping method, temperature differential method, douche, stripping method are difficult to the problem of disengaging product.
Especially for tubular composite material parts, since size is long, angle is small, and end is difficult to without stress point, conventional release method
Do not influence, damaged composite material part under the premise of, smoothly complete stripping process, the demoulding for being unable to satisfy such part is wanted
It asks.
Summary of the invention
The object of the present invention is to provide one kind to smoothly complete long size, low-angle under the premise of avoiding damage to part
Tubular composite material parts demoulding method.
The technical scheme is that a kind of tubular composite material parts release method, in tubular composite molding
When, symmetrical shop and part form integrated reinforcement block at Central of the parts line on the outside of the part mouth frame portion position, jack is fixed,
And mandril of lifting jack is withstood on as stress point on reinforcement block, part is axially pushed along shaping mould tire with jack force,
Complete part removal.
The jack being fixed on shaping mould tire ring flange is symmetrical two, is withstood on by various mandrils symmetrically arranged
On reinforcement block.
The jack is fixed at the end bulge-structure of shaping mould tire.
The end bulge-structure of the shaping mould tire is ring flange.
The reinforcement block of piece surface is cut after part removal.
The invention has the advantages that compared with prior art, it is de- that the present invention can solve long tubular low-angle composite material parts
Modulus problem guarantees not injuring part in knockout course, and easy to implement, and high-efficient, at low cost, wide adaptability can promote use
It is handled in the demoulding of similar tube shape component, there is biggish practical application value.
Detailed description of the invention
Fig. 1 is present invention part and mould tire one schematic diagram to be demoulded；
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- part, 2- mould tire main body, 3- ring flange, 4- jack, 5- mandril, 6- reinforcement block.
Specific embodiment
The present invention is described in further details below.
1 is please referred to, is present invention part and mould tire one schematic diagram to be demoulded.In figure, part is socketed in outside mould tire.
Referring to Fig. 2, 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, is used to support jack, conveniently stripped.
Referring to Fig. 3, it is part schematic diagram.Two reinforcement blocks of symmetrical shop, the reinforcement block on the outside of mouth frame portion position
To be made of one piece when tubular composite material manufacture, it is symmetrically distributed along part axis center, puts forth effort to prop up to provide when demoulding
Support point.
Referring to Fig. 4, 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 two mandril of lifting jack are withstood on respectively on two reinforcement blocks, with two
Reinforcement block axially pushes part along shaping mould tire as impetus, with jack force, completes part removal.Demoulding is completed
Afterwards, cutting composite material reinforcement block can be completed final part processing, and whole process will not cause to damage to part itself, effective guarantee
Quality during part removal.
The configuration of the present invention is simple, it is easy to operate, only need integrally formed reinforcement block, Ji Keji on tubular composite material in advance
The earth facilitates subsequent demoulding work.And jack of the present invention is it is not absolutely required to be fixed on mould tire ring flange, and it can also be straight
It connects and is fixed on elsewhere, such as ground or wall stationary plane, as long as mandril withstands reinforcement block, still achievable demoulding work.Cause
This release method of the present invention is simple, practical, and can be adapted for that various sizes are long, the small tube shape component of angle or cylinder part
Demoulding, has a large promotion value and practical value.
