Description
Technical field
The present invention relates to the processing and manufacturing technical field of cubing, more particularly to a kind of automobile gauge and its manufacture method.
Background technology
All the time, automobile gauge is fabricated by using aluminium.There is following technological deficiency in this mode：1）Aluminium
Density ratio is larger, so cause the cubing processed heavier, it is not easy to operate；2）The coefficient of expansion of aluminium is big, causes cubing to add
Precision is reduced when work is operated, and has stress corrosion dehiscence resistant tendency；3）After metal material long-time use, metal is easily produced tired
Labor, it is not corrosion-resistant, so as to have impact on use and the precision of cubing, it finally have impact on the quality of product；4）Manufactured and examined using aluminium
Tool, is generally all to use monoblock cast aluminium machining, this mode is high for the requirement of equipment, technique, and long processing time,
Waste of raw materials is serious.
At present, the technology of automobile gauge is manufactured using carbon fibre material with the presence of some.Such as Chinese patent《Use carbon fiber
Material as tool skeleton lightweight cubing》（Application number：201210167521.7）And Chinese patent《Carbon fiber automobile lamp
Cubing》（Application number：201210563450.2）, above-mentioned two technology is to prepare cubing by raw material of carbon fibre material merely, into
This is of a relatively high, and especially for the large-scale cubing as whole vehicle side, cost can only be described with costliness, and it is made
Integrated forming technique can not be used by making technique, and use after separately shaping packaging technology again, then reduces accuracy of detection.Together
When, by the fragility that carbon fibre material has, in narrow, thin-walled place, it is easily worked fracture.
The content of the invention
It is an object of the invention to overcome the defect of above-mentioned prior art high there is provided a kind of product strength, precision is had
Effect ensures that product cost reduction, cubing light weight can also realize integrated molding for large-scale cubing and processing technology is easy
Automobile gauge；
It is a further object of the present invention to provide the manufacture method of above-mentioned automobile gauge.
To realize that the technical scheme that the purpose of the present invention is taken is：
A kind of automobile gauge, it is characterised in that the automobile gauge is by the internal layer that is constituted with carbon fiber skeleton and is wrapped in carbon
The pasty state generation wooden outer layer of fiber reinforcement surrounding is constituted.
The internal layer constituted with carbon fiber skeleton is by carbon cloth and the resin thickness that laying is extremely designed successively, solidification
Obtained by molding.
Reinforcement is embedded with the internal layer constituted with carbon fiber skeleton.
A kind of manufacture method of above-mentioned automobile gauge, it is characterised in that its technique includes shaping and the pasty state of carbon fiber skeleton
Dai Mu coating parcel.
The carbon fiber skeleton is shaped to：First, cut carbon cloth is layed in mould, then pressed
Laying is carried out to the thickness designed, curing molding according to the order of one layer of resin, one layer of carbon cloth.
The laying of the carbon cloth is carried out with overlapping mode.
Before the laying of carbon cloth, reinforcement, fixed bonding are added in mould.
The coating parcel of the pasty state generation wood refers to：One layer of resin of brush, is then coated with first first on carbon fiber skeleton
Layer pasty state generation wood, is coated with next layer, sequentially into required thickness after solidification to be cooled.
The thickness of the first layer pasty state generation wood is 20~30mm, and the pasty state generation wooden thickness of remainder layer is 40~50mm.
The carbon fiber skeleton of the invention constituted using carbon fibre material adds whole automobile gauge as the internal layer of cubing
Intensity and rigidity, improve the impact capacity of cubing, using pasty state for carpentery workshop as the outer layer of cubing, be easy to processing, and processing conditions
Simply, preparation technology is simple, and flexible design disclosure satisfy that automobile diversified trend, realize the integrated molding of large-scale cubing；Together
Shi Caiyong carbon fibre materials, thermal coefficient of expansion is small, it is ensured that the precision of cubing, reduces manufacturing cost, and relative to traditional boat
Empty aluminium cubing has lightweight advantage, convenient operation.

Embodiment
The embodiment of the present invention is elaborated with reference to example.It should be understood that example is to be used for
Illustrate rather than limitation of the present invention.The scope of the present invention is determined with core content according to claims.
The automobile gauge of the present invention is the internal layer 7 being made up of carbon fiber skeleton and the pasty state for being wrapped in carbon fiber skeleton surrounding
In generation, wooden outer layer 8 was constituted, wherein the internal layer 7 constituted with carbon fiber skeleton is by carbon cloth and the resin thickness that laying is extremely designed successively
Obtained by degree, curing molding, and reinforcement is embedded with wherein.In automobile peripheral structure for example shown in Fig. 1, figure, 1, gusset A posts,
2nd, gusset B posts, 3, gusset C posts, 4, connect the back timber of A, B, C post, 5, connect the sill strip of A, B, C post, 6, rear tail-hood, 7, carbon it is fine
Tie up skeleton internal layer, 8, pasty state generation wooden outer layer.
The manufacture method of automobile gauge of the present invention is：
1st, mold design, 3D design datas CNC processes mould.
2nd, benchmark post, fixed bonding are embedded in a mold（Benchmark post is easy for follow-up machine tooling positioning）.
3rd, reinforcement, fixed bonding are added on mould.
4th, carbon fiber skeleton is prepared：A carbon cloth is layed in mould first, then according to one layer of resin, one layer
The mode of carbon cloth carries out laying, extremely the thickness of design, afterwards curing molding（Cold curing）.To be exerted oneself when brush resin
Carbon fibre cloth layer is extruded, bubble is excluded, makes every layer of carbon cloth（Carbon fibre cloth layer）It is brought into close contact with interlaminar resin.Laying can be used and taken
The mode connect is carried out.
5th, pasty state generation wood is coated on carbon fiber skeleton：After after carbon fiber skeleton forming, blowing clean top layer impurity, one layer of brush
Resin, is then coated with first layer pasty state generation wood, and coating thickness is coated with next layer in 20~30mm after solidification to be cooled, according to
The secondary thickness to needs（Vehicle side determines that thickness is determined according to customer need according to different automobile types, and with regard to one
Individual gusset, the thickness of difference is also different, is 50-400mm）, every layer of thickness is in 40~50mm afterwards, this design
Purpose is primarily due to：First layer is connected with carbon fiber skeleton, it is necessary to form certain rigid shape, so as to subsequent construction,
Limited later per thickness degree is that reaction is violent, and heat release is big, easily influences production because pasty state generation wood solidification meeting heat release, thickness is excessive
The performance of product；Construct after thickness, should not extrude, be compacted.
In pasty state generation wood construction, it is necessary to exclude bubble.
