Method for manufacturing titanium alloy straightener blade

Abstract

The invention discloses a method for manufacturing a titanium alloy straightener blade. The process flow comprises the following steps: A, preparing blanks; B, machining peripheral screw holes; C, milling a first reference surface; D, machining small positioning holes and milling a connecting surface; E, performing pre-connection pretreatment on the connecting surface; F, performing pre-connection assembly; G, performing diffusion bonding; H, performing post-connection milling; I, machining long oblique circular holes; J, performing post-connection treatment. The straightener blade manufactured with the method for manufacturing the titanium alloy straightener blade has the advantages of smooth surface, low cost and firmness in connection; moreover, the yield of the straightener blade manufactured by using the method is higher.

Description

technical field [0001] The invention relates to a method for preparing rectifying blades, in particular to a method for manufacturing titanium alloy rectifying blades. Background technique [0002] The original manufacturing process is blade material preparation → welding stop treatment → argon arc welding to seal the tight edge → diffusion connection → superplastic forming → shape edge machining. In addition to the diffusion connection equipment, the original manufacturing process also needs a gas source system, which has high requirements for equipment; ribs and cavities cannot be preset; cavities are naturally formed, and the size cannot be too small, which has limitations; heating time Long, the metal grain size grows seriously; the structure of the tooling is complex, and there must be a tight edge; the internal cavity and ribs are naturally formed, irregular; there are many processes and the process is complicated; the surface is not processed after forming, and the su...
