Problems solved by technology

[0002] At present, for the forming of composite wall panels with stiffeners, if traditional beams and skins are formed separately and then glued together, interface effects are likely to occur on the glued surfaces, and it is easy to debond when subjected to heavy loads, which affects flight safety. Therefore, it is necessary to Integral Forming and Curing of Wall Panels

Embodiment Construction

[0021] The present invention will be described in further detail below.

[0022] A composite wall panel forming tool with reinforcing ribs, the reinforcing ribs are in an inverted "J" shape, cover plate 3, positioner 4, positioning block 11, mandrel 5, rubber block 6, equalizing steel plate 7, wiring block 8. Occupying block 9, paving mold 10, compression screw 12, and vacuum bag 13. The mandrel 5 is used for the paving of the material in the C-shaped region on one side of the reinforcing rib, and is also used for the positioning of the beam reinforcing rib in the bonding forming process. The paving mold 10 is only used for the paving of the Z-shaped region on the side of the reinforcing rib. The cover plate 3 is formed by the cover plate forming tool 2, and its mold surface is the upper surface of the wall panel skin, which is used to abut against the upper surface of the wall panel skin during the bonding process to ensure the forming quality. A spacer 9 is added to the rib...

Abstract

The invention belongs to the field of composite forming, in particular to a composite reinforcing rib wall panel forming tool. For the conventional forming of a composite reinforcing rib wall panel, for example, the traditional beams and skin are singly formed and then bonded, the bonding surfaces are easy to generate an interfacial effect, the beams and skin are easily debonded under great load, the air safety is affected, and therefore the integral forming and curing of the wall panel is needed. In the integral forming process of the composite reinforcing rib wall panel, the method solves the problems of reinforcing rib positioning and forming pressurization and improves the forming quality and precision of the upper surfaces of parts.

Description

technical field [0001] The invention belongs to the field of composite material forming, and in particular relates to a composite material wallboard forming tool with reinforcing ribs. Background technique [0002] At present, for the forming of composite wall panels with stiffeners, if traditional beams and skins are formed separately and then glued together, interface effects are likely to occur on the glued surfaces, and it is easy to debond when subjected to heavy loads, which affects flight safety. Therefore, it is necessary to Integral form solidification of the siding. Contents of the invention [0003] The technical problems to be solved by the present invention are: the positioning of the reinforcing ribs and the forming pressurization in the overall forming process of the composite material reinforced rib wall plate, and the forming quality and precision of the upper surface of the parts. [0004] The technical solution of the present invention is: a composite m...
