Kind；A kind of conventional method is to guarantee the shape of truss members by metallic combination mould, metallic combination mould need with wallboard forming mould into
The reliable positioning of row, to guarantee the accuracy of truss members position；Bit combination mode structure for truss members is complicated, accuracy of manufacture requirement
Height, difficulty of processing is big, leads to the at high cost of product and shaping mould；
Another forming method is primary and secondary vacuum bag method: the cylindricality vacuum bag of prefabricated, similar tubular is filled into purlin
In the inner cavity formed between part and siding, it is coated with outer vacuum bag on the outer surface of Ω type reinforcing rib and siding, by cylindricality vacuum
The inner surface and Ω type reinforcing rib in space and outer vacuum bag between bag outer surface and the inner surface of Ω type reinforcing rib, siding it is outer
Another space between surface is connected and seals；The advantages of the method, is: reducing forming cost.But for the technical ability of operator
Level requirement is high, once vacuum bag gas leakage, it is easy to cause scrapping for part.
Summary of the invention:
The object of the present invention is to provide a kind of reinforcing rib siding co-curing forming methods.
Above-mentioned purpose is realized by following technical scheme:
A kind of reinforcing rib siding co-curing forming method, method the following steps are included:
(1) truss members is preforming；
(2) paving of wall panel skin；
(3) the position positioning of truss members；
(4) co-curing.
A kind of reinforcing rib siding co-curing forming method, the step (1) truss members are preforming:
Firstly, pressing preforming tool position first by the way of brush coating and manual paving on truss members preforming tool
Truss members is subjected to bending；After the completion, vacuum bag is pasted around the truss members after bending, vacuumized, vacuum degree is greater than 0.07
Mpa；It is carried out in curing oven preforming；80 ± 5 DEG C of preforming temperature, constant temperature 1 hour, heating rate was 2~5 DEG C/min.
A kind of reinforcing rib siding co-curing forming method, the paving of the step (2) wall panel skin: according to setting
Drawing requirement is counted, is successively laid on mold (or platform) by defined laying direction and sequence.
The position positioning of the step (3) truss members: a kind of reinforcing rib siding co-curing forming method is being put well
Placed as needed in the covering forming tooling of covering it is preforming after truss members and various locating pieces, and pass through laser-projector determine
It is each it is preforming after truss members and various locating pieces position, the inside of truss members, as support, guarantees purlin using hard silicon rubber core
Part shape during co-curing.Prevent truss members during co-curing from generating using positioning silicon rubber outside truss members simultaneously
Displacement.
A kind of reinforcing rib siding co-curing forming method, the step (4) co-curing: is passing through laser projection
Instrument, which determines, pastes vacuum bag around the truss members behind position and various locating pieces, is solidified in curing oven, solidification temperature is
180 ± 5 DEG C, soaking time is 150+10 min, and pressure is 0.4~0.6MPa, 1~3 DEG C/min of temperature rate.
Beneficial effects of the present invention:
1. the present invention for deficiency present in traditional technology and design provide it is a kind of for truss members siding co-curing
Forming method reduces frock cost, simplifies forming operation process.
The present invention greatly reduces the quantity of connector by the way of composite material skin and truss members co-curing, reduces
Assembly work amount, while reducing stress collection and neutralizing weakening of the rivet hole to siding section, alleviate the weight of connector itself
Amount；In addition, co-curing does not need the coordination between assembling assembly；The structural integrity of co-curing component is good.
