Abstract

The invention discloses an output gear shaft rotary forging die which comprises a female die, a swinging head male die and a connecting die. The connecting die is arranged on a forging shaft body section of a output gear shaft and is connected with the female die by a fixed key; the female die and the swinging head male die are respectively connected with a compressing plate. According to the output gear shaft rotary forging die disclosed by the invention, one-step processing forming of the output gear shaft is implemented, working hours are saved, materials are saved, convenience is provided for next processing, processing time of an integral machine is shortened, processing efficiency is improved and a length-diameter ratio of a casting reaches 3.1>2.5.

Description

technical field [0001] The invention relates to an output gear shaft swing rolling mold. Background technique [0002] The gear output shaft is an important part in mechanical design. At present, the output gear shaft is mainly processed by forging. However, the aspect ratio of the casting is difficult to reach 3.1>2.5, and the general forging method cannot be completed in one process. Contents of the invention [0003] In order to solve the problems existing in the casting process of the existing output gear shaft, the invention provides an output gear shaft oscillating mold. [0004] The technical solution of the present invention is: an output gear shaft oscillating die, including a die, a swing head punch and a connecting die, the connecting die is arranged on the shaft body section of the output gear shaft forging, and is connected with the die through a fixing key , the die and the swing head punch are respectively connected with the pressing plate. [0005] Pre...
