Abstract

The invention discloses a gear opener for forging gears, which comprises a die tooth block and a pull-back linkage mechanism for switching the use state of the die tooth block. The invention has the advantages that a group of die tooth blocks connected with the lower ring block can be conveniently and quickly switched and connected on the stamping block, the formed gear surface is matched with the space structure of the gear on the inner wall of the gear stamping die, the length of the die tooth blocks is half of the thickness of the gear, the whole is light, the die tooth blocks are completely different from the integrated tooth groove structure formed on the stamping block, the replacement operation strength is greatly reduced, the die tooth blocks are suitable for replacement and installation of the die tooth blocks with various specifications, the die tooth blocks press and trim the tooth edges of the primary stamping part along with the stamping block pressed downwards for the second time, the stamping quality of the edge part of the gear is improved, and the push-pull type locking piece is driven to penetrate out of the top of the guide hole or penetrate out of the bottom of the guide hole from top to bottom when moving upwards and downwards, so that the effect of conveniently releasing hanging and releasing the die tooth blocks independently during idle is achieved, and the standby state of a group of die tooth blocks which can be accessed at any time is achieved.
