| Abstract: | There was vertical flash on inner hole of forging by the forge die for blank of helical bevel gear. It is difficult to remove the flash and machine procedures follow-up. A new applied forge die is presented in the treatise. There are a float mould core and a float concave die in the die, forging forming within a closed ring cavity formed by two dies. The forgings without any flash can be produced with the new type of forge die and that weight of blank is decreased 5.5%. So that the cost of production is greatly decreased. |
