Abstract
The invention discloses a kind of small angle R Carbon fibe vehicle body production methods, comprise the following steps: first weaving Carbon fibe silk, are made into Carbon fibe cloth；Secondly Carbon fibe cloth is cut, cloth block needed for obtaining production rudimentary model；Then it by the accumulation of cloth block from level to level needed for each rudimentary model, is then squeezed with press, obtains rudimentary model；Some Carbon fibe silks are filled at the angle R of car body die again, and rudimentary model is put into car body die, then vacuumize car body die；Under vacuum conditions, resin is gradually filled into vehicle body grinding tool, resin is contacted with rudimentary model and the Carbon fibe silk of filling, and fusion is penetrated into rudimentary model；Resin in mold is solidified；After the completion of solidification, it is removed from the molds Carbon fibe vehicle body shaping workpiece.The present invention can be formed preferably at the angle R when resin is filled, in die R angle area filling fiber filament so as to form the lesser angle R in this way.
Description
Technical field
The present invention relates to automobile manufacturing fields, more specifically to a kind of small angle R Carbon fibe vehicle body production method.
Background technique
With the progress of development in science and technology, more and more automobile vendors use Carbon fibe as body material, including vehicle body
Main frame, car door and tailgate etc., but current technique will appear sky since the angle R is too small when carrying out Carbon fibe Auto-body manufacturing
Gas is arranged endless, and part resin lack of fill occurs and the problem of intensity deficiency falls off, so the angle R is typically designed minimum 3mm,
Practical manufacture causes appearance uncoordinated it is possible that the case where angle R reaches 5mm, thus the angle R will appear problem bigger than normal.
Summary of the invention
The technical problem to be solved in the present invention is that for current technique when carrying out Carbon fibe Auto-body manufacturing, the meeting of the angle R
There is problem bigger than normal, lead to the technological deficiency that appearance is uncoordinated, a kind of small angle R Carbon fibe vehicle body production method is provided.
The present invention solves its technical problem, and the used small angle R Carbon fibe vehicle body production method comprises the following steps:
S1, first Carbon fibe silk woven, is made into Carbon fibe cloth；
S2, Carbon fibe cloth is cut, cloth block needed for obtaining production rudimentary model；
S3, by the accumulation of cloth block from level to level needed for each rudimentary model, then squeezed, obtained preliminary with press
Model；
S4, some Carbon fibe silks are filled at the angle R of car body die, and rudimentary model is put into car body die, then
Car body die is vacuumized；
S5, under vacuum conditions gradually fills the Carbon fiber of resin, resin and rudimentary model and filling into vehicle body grinding tool
Silk contact is tieed up, and penetrates into fusion in rudimentary model；
S6, resin in mold is solidified；
After the completion of S7, solidification, it is removed from the molds Carbon fibe vehicle body shaping workpiece.
Further, in the small angle R Carbon fibe vehicle body production method of the invention, in step S4, according to R at each angle R
Angle size is equal to 1.5mm ± 50% and is filled completely with Carbon fibe silk with type.
Further, in the small angle R Carbon fibe vehicle body production method of the invention, solidification is carried out in step S6 and is referred to: from
So solidify or baking is carried out to mold and accelerates solidification.
Further, in the small angle R Carbon fibe vehicle body production method of the invention, in step S6, the temperature of baking is 60
To 80 degrees Celsius.
Implement the small angle R Carbon fibe vehicle body production method of the invention, has the advantages that and filled out in die R angle region
Fiber filament is filled, can preferably be formed at the angle R when resin is filled in this way, so as to form the lesser angle R.The present invention is in reality
In the treatment process of border, the angle R has reached 1.5mm or so.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing:
Fig. 1 is the flow chart of small one embodiment of the angle R Carbon fibe vehicle body production method of the invention；
Fig. 2 is the section schematic diagram of fiberfill fibers silk at the angle R.
Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
A specific embodiment of the invention.
It is the flow chart of small one embodiment of the angle R Carbon fibe vehicle body production method of the invention with reference to Fig. 1.A kind of small angle R
Carbon fibe vehicle body production method, comprises the following steps:
S1, first Carbon fibe silk woven, is made into Carbon fibe cloth.
S2, Carbon fibe cloth is cut, cloth block needed for obtaining production rudimentary model.
S3, by the accumulation of cloth block from level to level needed for each rudimentary model, then squeezed, obtained preliminary with press
Model.
S4, some Carbon fibe silks are filled at the angle R of car body die, and rudimentary model is put into car body die, then
Car body die is vacuumized；As a kind of preferred embodiment of the invention, it is equal to 1.5mm ± 50% according to the angle R size at each angle R
It is filled completely with Carbon fibe silk with type, such as is equal to 1.5mm fiber filament according to angle size at the angle R and is filled completely with type.With reference to figure
2, the straight line of the leftmost side and lower side indicates that mold wall, the two mold walls have the angle R, the angle R in figure at lower left in figure
Place's filling Carbon fibe silk, is identified using hacures in figure.
S5, under vacuum conditions gradually fills the fiber of resin, resin and rudimentary model and filling into vehicle body grinding tool
Silk contact, and fusion is penetrated into rudimentary model.
S6, resin in mold is solidified.Carry out solidification to refer to: spontaneous curing carries out baking quickening admittedly to mold
Change, the temperature of baking is 60 to 80 degrees Celsius.
After the completion of S7, solidification, it is removed from the molds Carbon fibe vehicle body shaping workpiece.At this point, Carbon fibe vehicle body shaping workpiece
It is coated with one layer of resin, internal also infiltration has resin.
The embodiment of the present invention is described with above attached drawing, but the invention is not limited to above-mentioned specific
Embodiment, the above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art
Under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, it can also make very much
Form, all of these belong to the protection of the present invention.
