Description
Technical field
The present invention relates to a kind of new processes for making carbon fibre rim.
Background technique
Carbon fibre rim is mainly made of the knife portion at middle part and the frame portion on periphery.Currently, common carbon fibre rim makes
Method is the filling gentle bag forming method of compression molding method, and above two method is that carbon fibre rim is integrally formed.Wherein, it is molded
The method of forming is that carbon fibre material is filled in the die cavity of molding die, presses and heats and be allowed to molding and obtain carbon fiber wheel
Circle.It but is solid using carbon fibre rim made from this method, therefore weight is larger.
The airbag method of forming is will to be stacked to by carbon fibre initial rinse material and be built-in with the wheel rim germule of an airbag, is placed into temperature
In the die cavity of 160~170 DEG C of mold, and two-period form inflation procedure and heating schedule are imposed on, to mold shape conjunction
Then the wheel rim is taken out at embryo at embryo in the wheel rim of the die cavity, and removes airbag therein, is sequentially carried out with rear rim at embryo
Heat dries sizing and surface processing program, and wheel rim finished product is just made.But the defect of this method is: airbag cabling is complicated, is easy report
It is useless, and the bore at each position of airbag is identical, bending part and variable diameter position in wheel rim germule, and fold occurs for airbag, so that
It can be flow in fold after carbon fiber heating, cause wheel rim inner wall to form irregular protrusion so that rough, so as to cause yields
It is low.
Summary of the invention
The purpose of the present invention is to provide it is a kind of make simple, obtained carbon fibre rim it is light-weight, can be significantly
Improve the new process of the production carbon fibre rim of yields.
The purpose of the present invention is realized by technical measures below: a kind of new process making carbon fibre rim, special
Sign be specifically includes the following steps:
(1) the knife portion of at least carbon fibre rim is made in the following ways:
1. making knife identical with knife portion shape portion mandrel；
2. liquid glue is coated in knife portion mandrel outer surface, until liquid glue is coated on completely on knife portion mandrel；
3. the affixing carbon fabric on the knife portion mandrel for be coated with liquid glue, formed be enclosed with the knife portion half of carbon cloth at
Product；
4. by by step, 3. the resulting knife portion semi-finished product for being built-in with knife portion mandrel are put into the die cavity of molding die；
5. pressing and heating die cavity, liquid adhesive curing, and it is inflated between liquid glue and knife portion mandrel, liquid glue expansion support
Carbon cloth compacting is played on the inner wall of die cavity, while knife portion mandrel heat shrinkable, when the temperature in die cavity reaches set temperature
When stop heating；
6. cooling die cavity；
7. opening molding die, the knife portion finished product being sleeved on knife portion mandrel is obtained；
8. clearing up the knife portion mandrel and liquid glue inside knife portion finished product, knife portion finished product is obtained；
(2) the frame portion of carbon fibre rim is made using following three kinds of modes:
1. first way:
Frame portion mandrel identical with frame portion shape is made, frame portion mandrel is made into integration with knife portion mandrel, (1) according still further to step
Described in 2.~8. step production obtain carbon fibre rim finished product；
2. the second way:
A. make identical with frame portion shape frame portion mandrel, according still further to step (1) described in 2.~8. step production acquisition frame
Portion's finished product；
B. combined and spliced knife portion finished product and frame portion finished product, obtain carbon fibre rim finished product；
3. the third mode:
A. frame portion finished product is made using the airbag method of forming；
B. combined and spliced knife portion finished product and frame portion finished product, obtain carbon fibre rim finished product.
The present invention is to coat liquid glue on the mandrel for copying carbon fiber wheel loop-shaped, the sticking carbon fiber on liquid glue
Cloth, then be placed in molding die form take out, finally by carbon fibre rim mandrel and liquid glue remove to obtain carbon fiber
Tie up wheel rim, due to carbon fibre rim be it is hollow, light-weight, use is light.And also avoid traditional airbag method of forming institute
The low defect of the yields of cause, while solving traditional airbag cabling complexity, it is easy the technical issues of scrapping；In addition, of the invention
Manufacturing process is simple, can increase substantially yields.
Liquid glue of the present invention has elasticity and toughness after becoming solid-state, therefore, being capable of expanding support in inflation
Carbon cloth is played, has the function of traditional air hose airbag.
The present invention step (1) 5. described in set temperature be that industry code requirement makes different carbon fibre pipe fittings
Product temperature to be achieved in prior art.Set temperature is 120~180 DEG C.
Using air hose glue, perhaps curing agent is added as the liquid glue air hose glue or latex in room temperature in latex to the present invention
It is in a liquid state under state (25 ± 5 DEG C), and being added after curing agent has elasticity and toughness；The preferred air hose glue of the present invention, air hose glue
It can brush in the mandrel outer surface of any moulding, while have the function of traditional air hose airbag, and elastic (toughness) ratio passes
Airbag of uniting is good.
As one embodiment of the present invention, pressure when pressing and heating die cavity is 15~30kg/cm2, heating temperature
Degree is 100~180 DEG C.As one embodiment of the present invention, the step (1) 6. in, cooling temperature when cooling die cavity
Degree is 55~65 DEG C.
The present invention in the step (2) 2. b. and (2) 3. in b., combined and spliced knife portion finished product and frame portion finished product be knife portion at
Product and frame portion finished product combination part smear viscose glue, and are fixed using clamp tool so that knife portion finished product and frame portion finished product bonding are at one
Body.
As a kind of preferred embodiment of the invention, knife portion mandrel and frame portion mandrel are all made of Poly Foam material system
At Poly Foam is a kind of material to be formed that foamed by high temperature after polystyrene (Polystyrene, PS) plus foaming agent, is usually cried
" foamed plastics ".The mandrel made of Poly Foam material is easy plasticity, and the meeting when forming high temperature when carbon fiber product is prefabricated
Melt and reduce, clears up and take out after facilitating molding.Knife portion mandrel and frame portion mandrel can also be strong using other plasticity, and in height
Temperature is lower to melt the material for reducing and being convenient to clean taking-up.
Compared with prior art, the present invention has following significant effect:
(1) the present invention is to coat liquid glue on the mandrel for copying carbon fiber wheel loop-shaped, the sticking carbon fiber on liquid glue
Cloth, then be placed in molding die form take out, finally by carbon fibre rim mandrel and liquid glue remove to obtain carbon fiber
Tie up wheel rim, due to carbon fibre rim be it is hollow, light-weight, use is light.
(2) the defect low the invention avoids yields caused by traditional airbag method of forming, and it is multiple to solve airbag cabling
It is miscellaneous, it is easy the technical issues of scrapping.
