Description
Technical field
The present invention relates to composite material parts manufacturing field, it is particularly suitable for composite material parts paving, in solidification process
Necessary vacuum line system structure.
Background technique
Composite material has many advantages, such as specific strength, specific modulus are high, corrosion-resistant, fatigue behaviour is good, and designability is strong,
The fields such as Aeronautics and Astronautics, rail traffic have been widely used.With the rapid growth of composite material usage amount,
The outer dimension of part constantly increases, and structure type is increasingly sophisticated, and developing risk is continuously improved.
The manufacture of composite material parts can be roughly divided into several stages such as blanking, paving, solidification, milling, detection.Wherein,
Paving is to form the significant process of composite material parts entity, and solidification is the key that then that physics, chemical change rank occur for raw material
Section.During paving, needs to vacuumize the air for excluding to wrap between laying, controllable, uniform compaction force is provided.Solidifying
Cheng Zhong then needs to exclude small molecule by-product by vacuumizing, and provides constant, uniform solidifying pressure.Therefore, vacuum line
The stability and reliability of system are most important for inside and outside portion's quality of composite material parts.
Currently, vacuum system needed for manufacture composite material parts can be divided into two major classes: Yi Leishi: not designing individually true
Empty set system, realizes conducting using auxiliary materials such as breathable fabrics merely.The using effect of this method is bad, particularly with structure
Complicated composite material parts, often will form false vacuum area, influence product quality;It is another kind of to be: by tooling surface
Air slot is set, installs the method building vacuum line system of fixed gas-guide pipeline additional.The using effect of this method is preferable, energy
It is enough that lasting, stable vacuum environment is formed in vacuum bag.But it improves the manufacture difficulty of tooling, and increase
Add potential gas leakage risk point, reduces system reliability.Gas-guide pipeline is fixed in tooling, once the problem that leaks air, is returned
It is high to repair difficulty, in some instances it may even be possible to tooling be caused to be scrapped.
Therefore, there is an urgent need to one kind to have high reliablity, install, reprocess, is easy to change, adaptable, can satisfy multiple
The needs of condensation material part complex appearance, and low-cost vacuum line system.
Summary of the invention
The present invention devises a kind of pin-connected panel vacuum line structure, can be in all kinds of tooling surface rapid build vacuum lines
System meets part paving, necessary in solidification process vacuumizes compacting requirement.
Technical scheme is as follows: a kind of pin-connected panel vacuum line structure, including air slot, cover board, Mobile vacuum
Pedestal, air slot be can splicing structure, the air guide around composite material parts is formed by slot section assembling combination of different shapes and is led to
Road, section be it is up-narrow and down-wide trapezoidal, side wall and bottom are evenly equipped with gas port;It is covered with cover board on air slot, is set on cover board
There is gas port;Air slot side is equipped with Mobile vacuum pedestal.
The method that auxiliary vacuumizes is carried out using this pin-connected panel vacuum line structure, is included the following steps:
1 will answer material paving in tooling;
The 2 multiple material part surrounding assembling combination air slots good in paving are placed in multiple material part in air guide path, and installation moves
Dynamic vacuum base;
3 cover cover board;
4 coat air slot, cover board and multiple material part with vacuum bag;
5 connect the Mobile vacuum mouth on Vacuumizing bag with Mobile vacuum pedestal, and respectively with pumped vacuum systems and vacuum
Monitor utensil connection;
6, which are put into autoclave, is solidified.
The present invention has following advantage:
(1) it by circumscribed vacuum line system, avoids in tooling surface and internal installation gas-guide pipeline, to vacuum tube
Road system itself reduces gas leakage risk point that may be present in composite material parts manufacturing process, improves without airtight requirement
System global reliability;
(2) vacuum line multistage split-mounting type designs, adaptable, can satisfy the use of all kinds of composite material parts
It is required that;
(3) vacuum line installation, remove convenient, can satisfy the demand of mass production;
(4) vacuum line is separated with shaping mould, is reduced vacuum line quantity, is reduced production cost;
(5) internal system has an air slot of perforation, intensive gas port on side wall, and air guide is high-efficient.
Detailed description of the invention

To be up-narrow and down-wide trapezoidal, side wall and bottom are evenly equipped with gas port;Cover board 3 is covered on air slot 1, cover board 3 is equipped with air guide
Hole;1 side of air slot is equipped with Mobile vacuum pedestal 4.
The method that auxiliary vacuumizes is carried out using this pin-connected panel vacuum line structure, is included the following steps:
1 will answer material paving in tooling;
The 2 multiple material part 2 surrounding assembling combination air slots 1 good in paving are placed in multiple material part 2 in air guide path, pacify
Fill Mobile vacuum pedestal 4;
3 cover cover board 3;
Vacuum bag is coated air slot 1, cover board 3 and multiple material part 2 by 4;
5 connect the Mobile vacuum mouth on Vacuumizing bag with Mobile vacuum pedestal 3, and respectively with pumped vacuum systems and vacuum
Monitor utensil connection;
6, which are put into autoclave, is solidified.
Present apparatus structure is simple, easy to use, and vacuum line system itself is without airtight requirement, high reliablity.The present apparatus is suitable
It is strong with property, vacuum line system can be constructed on all types of faces, especially complex profile.
