Problems solved by technology

This will cause a large number of parts to be manufactured separately and then assembled. The assembly process is mostly glued and riveted. The process is complicated, the manufacturing time is long, and it requires a huge workload, which directly results in high production costs.
For UAVs that need to achieve low-cost manufacturing, the above-mentioned manufacturing methods cannot meet the needs of low-cost manufacturing

Embodiment

[0032] Substitute wood resin is used as the material of the airfoil surface mold 1. After curing, the main body of the mold 1 is formed. The mold surface is processed by CNC, and finally the surface is corrected and gel-coated to complete the manufacture of the airfoil surface mold. The root clip 2 and the end clip 3 are also manufactured in this way. The mold support 9 adopts steel structure welding, and the airfoil surface mold 1 is fixed on the mold support 9 .

[0033] Processing of the trailing edge forming press plate: FRP composite material is used as the main material, and wood resin is bonded on the forming surface, and then the trailing edge forming surface is processed by CNC machine, and the surface paint is sprayed.

[0034] Processing of rib positioning platen: FRP composite material is used as the main material, and wood resin is bonded on the forming surface, and then the outer forming surface of the wing rib of the composite airfoil is processed by CNC machini...

Abstract

The invention provides a composite wing molding and assembly integration mold. The molding and assembly integration mold comprises a wing profile surface mold, a root clamping plate, an end clamping plate, a front edge pressing plate, a back edge molding pressing plate, a rib positioning pressing plate, a main wing beam limiting block and a wing rib fixed rod. The molding and assembly integrationmold realizes the assembly and curing integration of all parts, and can realize manufacturing of back edges during assembly; and the assembly, the back edge preparation and the co-curing can be finished through one set of molds.

Description

technical field [0001] The invention relates to an integrated mold for forming and assembling a composite material wing, which belongs to the technical field of mold manufacturing. Background technique [0002] Composite material structures are more and more used in the aerospace field because of their higher specific strength and specific modulus than metal materials. Composite materials have been successfully used from military aircraft to civilian aircraft, especially the wing as the main load-bearing component, which requires higher strength and stiffness to ensure the performance and safety requirements of the flight process, so carbon fiber composites become the wing The main material of the structure. [0003] When composite materials are used as structural materials, internal defects of materials must be avoided as much as possible, including lack of glue, voids, delamination, etc. Therefore, in order to ensure product quality, the commonly used manufacturing proces...
