WebIn this paper, the cold orbital forging die is designed to make a hollow ring gear part. The forging process with suitable preform design is proposed to obtain the sound cold orbital forging gear part. Different preform designs have been studied to find out the deformation characteristic of the orbital forging process. WebFeb 3, 2016 · Cold orbital forging is an advanced spur bevel gear forming technology. Generally, the spur bevel gear in the cold orbital forging process is formed by two steps: the preforming step and the final step. Due to the great importance of the final step to gear forming and its complication with interactive factors, this work aims at examining the …
