Forming die for composite dual-insertion lug piece of solar energy unmanned aerial vehicle engine compartment

Abstract

The invention discloses a forming die for a composite dual-insertion lug piece of a solar energy unmanned aerial vehicle engine compartment. The forming die comprises a connecting bottom plate, positioning pins and fastening bolts, wherein a supporting swage die is arranged on the connecting bottom plate, a first fixing seat and a second fixing seat are respectively arranged at the positions, at the two ends of the supporting swage die, of the connecting bottom plate, a left swage die is arranged on the left side above the first fixing seat and the second fixing seat, a right swage die is arranged on the right side above the first fixing seat and the second fixing seat, a compression die is arranged at the middle position above the first fixing seat and the second fixing seat, and the inner side molded surfaces of the left swage die, the right swage die and the compression die transmit pressure through silica gel pressure equalizing plates so as to compact a composite part. According to the forming die, the supporting swage die, the left swage die, the right swage die and the compression die form a combined matched-die mode, so that the assembly, the disassembly and the demolding are convenient and simple, the die assembly is positioned by virtue of the positioning pins, the fastening bolts are fastened, and it is ensured that the size and the precision of a composite materialworkpiece are stable.

Description

technical field [0001] The invention relates to the field of UAV material forming technology, in particular to a molding die for composite material double-insert lugs of a solar UAV power cabin. Background technique [0002] Compared with military or civilian manned aircraft, UAVs are different in terms of use and mission requirements. UAVs usually have the characteristics of low cost, light structure, high stealth, long endurance, and high storage life. For unmanned For combat aircraft, there are also requirements for high maneuverability and large overload. Composite materials have high specific strength and specific stiffness, strong designability, good fatigue performance, light weight, corrosion resistance and other excellent properties, and are widely used in the aerospace field; [0003] In the existing advanced composite material manufacturing technology, composite material parts generally adopt the design form of female mold or male mold, and it is difficult to ensu...
