Forging die for special-shaped bearing outer ring forge piece

Abstract

The utility model discloses a special-shaped bearing outer ring forge piece forging die which comprises an upper die, a lower die and a core die, a plurality of first grooves and second grooves for forging are formed in the center of the lower surface of the upper die and the center of the upper surface of the lower die, and the first grooves and the second grooves are in one-to-one correspondence. The first grooves and the second grooves jointly form a mold cavity, the multiple first grooves and the multiple second grooves are communicated through first arc grooves and second arc grooves correspondingly, the first arc grooves and the second arc grooves jointly form a mounting hole, and the core mold is composed of a fixing rod, four first modules and four second modules. The fixing rod is located in the installation hole, the four first modules and the four second modules are installed at intervals and form a ring shape to be located on the outer side of the fixing rod, and the bearing outer ring core mold has the advantages that the core mold can be rapidly formed, meanwhile, after forging is completed, the core mold can be conveniently and rapidly taken out of a bearing outer ring, and work efficiency is greatly improved.
