Titanium alloy blade isothermal adjustment die design

TC11 titanium alloy blade is one of aircraft engine important parts, its shape is complex and the quality requirement is high. The warps and the forgings may be discard due to the formed forging's remaining stress and the temperature stress. But it is possible to use the isothermal adjustment process to reduce the warp distortion and make the blade shape to meet the qualified requirements. Three dimensional design software Pro/E was used to carry on the design in view of the uniform temperature adjustment mold, and which Pro/E software can mainly solve the mold cavity modeling problem. The three dimensional surface modeling of blade is carried out and the heating and cooling devices for the isothermal sizing die are designed simultaneously. Its design flow is: creating the three dimensional entity of the blade, adding margin to the blade, using entity to set up the mold cavity, adding the mold structural elements, and designing heating and cooling system.
