A DIE WITH HORIZONTALLY PARTING FEMALE DIES FOR CROSS-PIECE FORGINGS Russian patent published in 2015 - IPC B21J13/02 B21K1/76 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming and may be used in forging of cross-pieces. Male die is arranged at top mould top plate. Bottom female die is arranged at bottom plate with crossbar. Top and bottom female dies have joint surface with equal central and peripheral sections. Top female die is coupled with crossbar by ties and arranged to displace relative to bottom female die to make a closed die chamber. Ejector is arranged in bottom female die to rest via spring-loaded pusher on said crossbar. Peripheral sections of parting surface of said female dies are inclined to side surface thereof. Said ties are arranged in through straight slots made at opposite side walls of female dies parallel with the mould mirror axis. This results in tight camping of female dies over forged-piece contour owing to plastic deformation of macro irregularities and waviness unavoidable after finishing of female die contact surfaces.

EFFECT: accurate alignment of female dies.
