Description
Technical field
The present invention relates to a kind of manufacturing method of wheel hub, a kind of side being manufactured composite wheel hub by preform
Method.
Background technology
Alleviate car mass, reduction fuel oil consumption and minimizing exhaust emission and become the key problem of automobile industry development, car
Wheel is one of important safety parts of automobile, as the nonspring carried mass of automobile, its quality alleviate alleviating than miscellaneous part
More important.Carbon composite is used to manufacture automotive hub than aluminium alloy wheel hub loss of weight 20～40% at present.The most existing vapour
Wheel hub production method has prepreg method, and its step is the one piece of preimpregnation that will slightly cut out on a ready formpiston or former
The shape sanction that tablet lay requires to die surface according still further to mould goes unnecessary part, according to level, the machine direction of design
Every layer carries out different changes, ceaselessly to catch up with pressure so that fitting between layers and reducing bubble by artificial simultaneously.Additionally
Prepreg laying forming also can be divided into vacuum bag molded and to mould extrusion forming.Can be compared although vacuum bag is molded
Closely knit product structure, but it can only ensure the one side size of product, and the size of product opposite side needs to carry out secondary again and adds
Work.Although mould extrusion forming can be obtained the two-sided dimensional accuracy of product, but due to each artificial lay discreteness,
The discreteness of prepreg resin content has resulted in the inhomogeneities of interiors of products quality, usually produces internal flaw, as bubble,
Lean glue, fiber fold etc., and the method a large amount of manual operations of needs, manpower and materials consume big, have bigger shadow to properties of product
Ring, should not produce in enormous quantities.
Also have a kind of method manufacturing wheel hub introduced by patent CN 102653138 A, mainly use resin vacuum to lead
Entering technique and manufacture a hollow wheel hub without spoke, resin vacuum introducing technology is by passing through evacuation in die cavity simultaneously
Resin is imported to the method for then curing molding in fibre structure by outside atmospheric pressure.But this method disadvantageously,
Because it is that nature sucks resin, fiber content is low, and its wheel hub manufactured does not has spoke, has harsh knot so can not manufacture
Structure performance requirement, complex-shaped single piece type automotive hub.
Summary of the invention
In order to overcome said method shortcoming, the present invention is by making one in advance with the fibre reinforced materials without resin system
Individual or multiple preforms, are then filled in a mold cavity closed, evacuation in the mold cavity that will close, then with compressing
Resin system is injected in die cavity by gas, cured after obtain composite wheel hub.
Preferably, described preform is made up of one or more preforms.
Preferably, described fibre reinforced materials is fiber, fabric or its mixture；Described fiber, is glass fibre, carbon fibre
Dimension, aramid fiber, basalt fibre, organic fiber or the wherein assorted fibre of more than two kinds.
Preferably, described resin system is epoxy resin, phenolic resin, polyester resin, cyanate ester resin, multicomponent heterocycle tree
One or two or more kinds in fat and corresponding firming agent thereof.
Preferably, described compressed gas is the air being dried or the nitrogen of compression.
Preferably, described evacuation, its vacuum is 1～100Pa；Resin system is injected into mould by described compressed gas
In chamber, injecting air pressure is 1～7MPa, keeps pressure 1～30min after injection.
Concretely comprising the following steps of said method:
1) the two or more structure split into by laying and the technological requirement of product by overall wheel hub structure is as preformation
Body models is fabricated to preform；
2) above-mentioned preform is placed according to fractionation order the entirety of the closing designed according to overall wheel hub structure
Mould in, close mould, mould whole constant temperature preheated, the temperature of above-mentioned constant temperature preheating is less than the resin system that will inject
Gelling temp, die cavity evacuation；
3) by compressed gas, the resin system of preheating is injected in mould, inject and after terminating, stop evacuation, keep
Pressure a period of time；Or first stop evacuation, and by compressed gas, the resin system of preheating to be injected in mould, injection terminates
After, keep pressure a period of time；
4) being heating and curing by mould, solidification end is dismantled mould after being cooled to room temperature and is taken out product.
The present invention, before resin by injection system in mould, evacuation, according to gas equation (when constant temperature) airtight
Space (gas flow is without increase and decrease), it is known that P1V1=P2V2, (P is gas pressure intensity；V is gas volume) at V1The space gases pressure of volume
Power is 1Pa air pressure, when only injecting liquid resin system with 1MPa pressure in space, according to the original 1Pa of the equilibrium principle of power
The gas pressure of pressure will rise to 1MPa, and the gas originally occupying whole space can only be occupied original sky by what resin extruded
Between 1/1000000th i.e. V2=V1P1/P2, then V2=0.000001V1.Define with the ratio of bubble volume with whole small product size
For voidage, voidage the most now is 0.0001%, and uses its voidage of product of prepeg process molding to be more than more
0.1%；Resin by injection system of the present invention is injected in mould by compressed gas, and keeps pressure a period of time after injection terminates
Delayed with overcome viscosity flow liquid to flow in slight void, make resin be easier to inject in the reinforcing material that laying density is big,
Make acceptable reinforcing material volume content strengthen, reach the purpose that reinforcing material volume content is controlled, and then control and improve
The mechanical strength of wheel hub.The composite wheel hub that the present invention manufactures, voidage is extremely low, and fiber content is high, and fiber is at composite
Structure is evenly distributed, corrugationless, and, owing to the manufacture of preform can be carried out with piecemeal, can be by complicated Disassembling Products
Becoming the combination of simple shape parts, see accompanying drawing 1,2, therefore, production efficiency is high, quality controllable, stable.
