Large titanium alloy blade upsetting blank manufacture mold with heads on two ends, and blank manufacture method thereof

Abstract

The invention discloses a large titanium alloy blade upsetting blank manufacture mold with heads on two ends. The mold comprises a large head gathering and shaping mechanism and a small head gatheringand shaping mechanism, wherein the large head gathering and shaping mechanism comprises a large head backward blocking base as well as a first large head gathering module, a second large head gathering module, a third large head gathering module and a large head shaping module which are successively disposed on the large head backward blocking base from top to bottom; and the small head gatheringand sharing mechanism comprises a small head backward blocking base as well as a first small head gather module, a second small head gathering module and a small head shaping module which are successively disposed on the small head backward blocking base from top to bottom. Through design of a specific three gatherings + one integration processing structure for a blank large head end, and designof a specific two gatherings + one shaping processing structure for a small head end, blade end shaping blank manufacture is realized. With the more exquisite gathering processing structure, occurrence of defects such as gathering instability and burr folding caused by excessive deformation can be avoided effectively, and batched production demands can be satisfied reliably.

Description

technical field [0001] The invention relates to the technical field of titanium alloy blade upsetting billet making, in particular to a large titanium alloy blade upsetting die with heads at both ends and a billet making method thereof. Background technique [0002] Titanium alloy is a new type of metal structure material developed after World War II. Its main features are small specific gravity and high strength, so it has high specific strength, good heat resistance and corrosion resistance, and is widely used in the aviation industry. However, the deformation resistance of titanium alloy is large, the forging interval is narrow, and it is sensitive to the change of process parameters such as forging speed and deformation amount. A certain type of engine has a large titanium alloy blade with two heads at both ends. The ends are large, the blade body is wide, long and thin, and the cross-sectional area of ​​the axis varies greatly. It is difficult to realize the blanking of...
