Abstract

The invention discloses a composite material small pit forming and pressurizing device. The composite material small pit forming and pressurizing device comprises a forming mold and a composite material structural part; a small pit is arranged in the forming mold, a small boss is arranged at the bottom of the composite material structural part, the small boss is arranged in the small pit, a plurality of tightly-arranged pressurizing blocks are arranged inside the small boss, an arc-shaped groove is formed in the top angle of each pressurizing block, the arc-shaped grooves are connected in sequence to form a conical hole, and a conical core shaft is arranged inside the conical hole. According to the composite material small pit forming and pressurizing device, the pressurizing balance of the small pit structure of the product composite structural part in the forming process is improved, and the product size precision is improved.

Description

technical field [0001] The invention relates to the technical field of process equipment, in particular to a composite material small pit forming pressurization device and a pressurization method. Background technique [0002] Composite structural parts have the advantages of light weight, high strength and rigidity, and good molding processability. They are more and more widely used in the aircraft manufacturing process, and composite structural parts with more complex shapes. [0003] Composite structural parts with complex shapes can be formed in one piece, or assembled after each part is formed. Compared with the combination assembly method, the one-piece molding method has the advantages of high precision, short cycle time, and light weight, and has been more and more used in the production process of complex composite structural parts. [0004] Some composite structural parts have some small-sized pits, which are directly pressurized by vacuum bagging during the moldi...
