Spiral bevel gear forging apparatus

摘要

A spiral bevel gear forging apparatus for forging a blank includes a first mold core having a mold cavity for receiving the blank, a first punch rod inserted movably into the first mold core and having a positioning end extending into the mold cavity for releasable engagement with a bottom of the blank, at least one push mechanism, and a drive mechanism. When the drive mechanism is operated to move from a non-ejecting to an ejecting position, the push mechanism is actuated to drive the first mold core to rotate about the first punch rod, and the first punch rod is actuated to move relative to the first mold core such that the positioning end thereof is moved out of the mold cavity for ejecting the blank out of the first mold core.

主权项

1. A spiral bevel gear forging apparatus for forging a blank, said spiral bevel gear forging apparatus comprising:
a first mold unit including a first mold core having a mold cavity for receiving the blank, and a first punch rod inserted movably into said first mold core and having a positioning end extending into said mold cavity for releasable engagement with a bottom of the blank; and a stripping unit including
at least one push mechanism capable of driving said first mold core to rotate about said first punch rod, anda drive mechanism operable to move between a non-ejecting position and an ejecting position; wherein, when said drive mechanism is operated to move from said non-ejecting position to said ejecting position, said push mechanism is actuated by said drive mechanism to drive said first mold core to rotate about said first punch rod, and said first punch rod is actuated by said drive mechanism to move relative to said first mold core such that said positioning end of said first punch rod is moved out of said mold cavity for ejecting the blank out of said first mold core.
