Abstract
The invention relates to a method for processing a machinery sectional material with carbon fiber. In the method, an inner model and an outer model of a mould are designed according to the structure of a sectional material, and then a carbon fiber cloth which is immersed in epoxy resin glue is repeatedly wound on the inner model of the mould until the thickness reaches the design requirement; the inner model is drawn out, the outer model is closed, the appearance shape required by design is extruded; and finally, high-pressure air is blown in an inner cavity, the required carbon fiber sectional material is formed after high-temperature solidification. The processing method provided by the invention is simple in process and is easy to achieve, and the success rate of a product can be greatly improved so that the product quality rises.
Description
Technical field
The present invention relates to a kind of method of using carbon fiber processing equipment section bar.
Background technology
Carbon fiber novel composite resin material is in light weight because of it, and has high strength, high rigidity and characteristics such as good creep resistant and corrosion resistance, is considered to a kind of very desirable lightweight material always.But for a long time, Ang Gui price hampers the extensive use of carbon composite at industrial circle always.But, along with cost-effectiveness changes gradually, this novel composite material can get more and more in industrial application.Except lightweight, carbon fibre composite also has significant performance aspect collision energy-absorbing, generally is six to seven times of steel, is the three-to-four-fold of aluminium.
Carbon fibre composite, other performances relatively, loss of weight makes industrial producers most interested, because the power that it can improve equipment.When the designer utilizes the various performances of this material to carry out product design, think that no longer simply it is a kind of substitution material, but this material can also bring more benefit.Carbon fibre composite has above-mentioned advantage, but in the mechanical arm industry because its shape, size and need processing and need certain factors such as machining accuracy restriction is never used.
Summary of the invention
The objective of the invention is to needs, provide a kind of technology simple, the processing method of the carbon fiber section bar that is easy to realize at present mechanical arm processing industry.
Technical scheme of the present invention is as follows: a kind of processing method of carbon fiber section bar comprises the steps:
(1) according to the internal mold and the external mold of the structural design mould of section bar;
(2) will on mould inner mould, twine repeatedly at the carbon cloth after soaking in the epoxide-resin glue, reach designing requirement until thickness;
(3) take out internal mold, the external mold that closes is squeezed into the outer shape of design;
(4) blow pressure-air at inner chamber, behind hot setting, form the carbon fiber section bar that needs.
Further, the processing method of aforesaid carbon fiber section bar, wherein, described mould is a metal material, is equipped with the epoxide-resin glue passing away in the front and back of external mold.
Further, the processing method of aforesaid carbon fiber section bar, wherein, the pressure of step (4) mesohigh air is 0.3Mpa～0.5Mpa, the time of blowing pressure-air is 20～25 minutes.
Further, the processing method of aforesaid carbon fiber section bar, wherein, the temperature of solidifying in the step (4) is 140 ℃～160 ℃, be 100～140 minutes hardening time.
Beneficial effect of the present invention is as follows: because moulding external mold of the present invention adopts the metal manufacturing, and metal die long service life (＞25000 times), surface quality is good.Mould structure is a combining form, and location, locking, unlatching, sealing device are arranged, and is easy to use.There is resin glue to get rid of passage before and after the mould, and can forms complete path, thereby improve the goods success rate greatly, make quality of item rise.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in detail.
As shown in Figure 1, the processing method of carbon fiber section bar comprises the steps:
(1) according to the internal mold and the external mold of the structural design mould of section bar;
As Fig. 2, shown in Figure 3, internal mold 1 and external mold 2 all adopt metal material, as steel, cast steel, steel alloy, or other performance materials similar, guaranteed the service life of mould, and made section bar have favorable surface quality.External mold 2 is that two parts are formed up and down, can be buckled on the internal mold 1, and there is passage 3 front and back of external mold 2.
(2) will on mould inner mould, twine repeatedly at the carbon cloth after soaking in the epoxide-resin glue, reach designing requirement until thickness;
As shown in Figure 4, carbon cloth 4 repeatedly twines repeatedly in internal mold 1 upper edge all directions, until the thickness requirement that reaches design.
(3) take out internal mold, the external mold that closes is squeezed into the outer shape of design;
As shown in Figure 5, after the carbon cloth 4 that is soaked with epoxide-resin glue is wound into the thickness of regulation, internal mold can be extracted out from carbon cloth, external mold 2 then closes, by positioning and locking device 5 external mold 2 is locked, the front and back of external mold 2 have resin glue to get rid of passage, and can form complete path, thereby improve the goods success rate greatly.
(4) blow pressure-air at inner chamber, behind hot setting, form the carbon fiber section bar that needs.
The pressure of pressure-air is 0.3Mpa～0.5Mpa, and the time of blowing pressure-air is 20～25 minutes.The temperature of solidifying is 140 ℃～160 ℃, and be 100～140 minutes hardening time.
Claims (4)
