| description | PURPOSE:To forge a large-sized turbine blade with a small capacity forging equipment by performing finish forging with plural split forgings in the case of performing, finish forging, shape forging and torsional forming the perform performed by elongating with forging the ingot of heat resistant alloy for forging after its blooming. CONSTITUTION:A forging stock 1 is divided into plural parts 2-1, 2-2, 2-3, 3-1, 3-2 in finish forging. And in a 1st split forging the parts corresponding to the unforging parts 3-1, 3-2 of dies 4-1, 4-2 are formed in a deep die-milling part 5 so as to forge the parts 2-1, 2-2, 2-3 only. Then, in a 2nd split forging the part corresponding to the unforging parts 2-1, 2-2, 2-3 of dies 7-1, 7-2 is formed in a deep die-milling part 6 so as to forge the parts 3-1, 3-2 only. |
