Embodiment 1
[0036] This embodiment is aimed at the six-layer titanium alloy hollow hybrid structure rudder blade with built-in preset blocks. The shape of the formed parts is as follows figure 2 As shown, the flow chart of its specific manufacturing method is as follows figure 1 Shown, now list specific examples for illustration:
[0037] 1) Manufacture the corresponding preforming A mold 1 and the superplastic forming / diffusion connection mold according to the shape of the formed part. The three-dimensional diagram of the superplastic forming / diffusion connection mold is as follows image 3 shown;
[0038] 2) According to the load on the shape of the part, the grid size and distribution of the core plate are obtained by topology optimization design, the original core plate and panel are obtained by laser cutting, and the preset blocks are obtained by mechanical processing. The original core plate, The three-dimensional diagram of the panel and preset block is as follows Figure 4show...
Embodiment 2
[0046] This embodiment is aimed at the four-layer plate titanium alloy hollow hybrid structure rudder wing with built-in preset blocks, and the shape of the formed parts is as follows figure 2 Shown, now list specific examples for illustration:
[0047] 1) Manufacture the corresponding superplastic forming / diffusion bonding mold according to the shape of the formed parts 3, the preforming B mold 8 and the intermediate mold 9, the three-dimensional diagram of the superplastic forming / diffusion bonding mold is as follows image 3 As shown, the cross-sectional schematic diagram of the preformed B mold 8 and the intermediate mold 9 is as follows Figure 7 As shown, in order to facilitate the laser pre-welding of the junction area between the subsequent lattice area and the four-layer board area, the lattice area of the middle mold is designed as a platform structure;
[0048] 2) According to the load on the shape of the part, the grid size and distribution of the core plate ar...
