A kind of typical structure type in part.Currently, the forming method of " J " shape composite material rib part is " two-step method " molding, i.e.,
Using manual laying mode, " C " shape precast body and a Z-shaped precast body are first made respectively, then by " C " shape precast body
" J " shape structure rib is combined into Z-shaped precast body.However, the forming method is in mobile combination " C " shape precast body and Z-shaped
When precast body, it is easy the final bonding quality for making precast body deformation influence part, and the forming method is not suitable for composite material
The automated manufacturing of rib part produces.
Summary of the invention
Part is influenced for deformation in precast body moving process existing for solution " J " shape composite material rib art methods
Bonding quality problem, and the part automated manufacturing of composite material rib can not be suitable for and produce problem, the present invention provide one kind
Forming Quality is good, bending and molding method suitable for automated manufacturing,.
A kind of forming method of J-shaped composite material rib of the invention, step are as follows:
The lower-left briquetting 1 and bottom right briquetting 2 of S1, horizontally disposed bend forming die, between lower-left briquetting 1 and bottom right briquetting 2
Draw bar 7 is set；
S2, the prepreg 6 of composite material is laid on the lower-left briquetting 1 and bottom right briquetting 2 of bend forming die；
S3, laminate panels 4 in the left laminate panels 3 of bend forming die and the right side are placed to prepreg 6, and be compacted；
S4, it is pulled up draw bar 7, prepreg 6 is bent into " several " font；
S5, will be bent into 6 top of " several " font prepreg shearing open, form it into " youngster " font；
S6, draw bar 7 is removed, makes that lower-left briquetting 1, bottom right briquetting 2, laminate panels 4 are moved to centre simultaneously in left laminate panels 3 and the right side
It is dynamic, prepreg 6 is compacted "T"-shaped；
S7, the upper laminate panels 5 for translating mold translate, and "T"-shaped prepreg 6 is bent into " J " shape.
Each briquetting of the bend forming die can be individually moved above and below providing, the pressure of left and right directions.
The angle that each briquetting of the bend forming die is contacted with prepreg is formed with chamfering.
Briquetting in the bend forming die is made by metal material.
The present invention has following actively effect compared to " two-step method " forming technique of existing " J " shape composite material rib part
Fruit, the present invention solve precast body during manual laying forming without making processing " C " shape precast body and Z-shaped precast body
It is easily deformed problem, ensure that quality.Meanwhile the present invention realizes the continuous bending movement of " J " shape composite material rib, improves
Automated manufacturing can be achieved in efficiency.

Specific embodiment
In order to further illustrate rather than limitation above-mentioned implementation of the invention, with reference to the accompanying drawing to the present invention into one
Step explanation, but therefore do not limit the present invention among the practical range.All these designs should be regarded as this technology institute
Disclosure and protection scope of the present invention.
Embodiment 1
See Fig. 1, this part is gathered around there are three bending type face, and wherein bottom end is symmetrical bending type face, and top is towards side
Bending type face.A kind of forming method of J-shaped composite material rib of the invention, is formed by following steps:
Step 1 is laid in prepreg on bend forming die；
Prepreg is bent into " several " font by mechanical traction power mode by step 2；
Step 3 will be bent into the shearing of " several " font prepreg top and open, forms it into " youngster " font；
The left and right briquetting of step 4, mold middle layer is mobile to centre, prepreg is compacted "T"-shaped；
Step 5 is translated by the briquetting on mold upper layer, "T"-shaped prepreg is bent into " J " shape.
Embodiment 2
The forming method of " J " shape composite material rib part of the invention, step are as follows:
Step 1 is laid in prepreg 6 on the lower-left briquetting 1 and bottom right briquetting 2 of bend forming die；
