The invention discloses a
forging molding technological method for a multi-lug part. The
forging and molding technological method for the multi-lug part is completed according to the following steps that firstly, blanking and heating are conducted, wherein heating is conducted after a
round bar blank is blanked; secondly, flattening is conducted, wherein one end of the
round bar blank is arranged on a pressing die, and after the pressing die is closed once, one end of the
round bar blank is flattened; thirdly, upsetting pressing is conducted, wherein the flattened end of the round bar blank is vertically inserted into a blank forming die cavity of the pressing die, upsetting pressing is conducted on the other end of the round bar blank, and therefore a blank with the outline matched with a cavity of a pre-
forging die is obtained; fourthly, forging molding is conducted, the blank obtained after blank forming is conducted is put into the pre-forging die to be pre-forged, and then the pre-forged blank is input into a final-forging die to be forged into a finished blank. According to the forging molding technological method for the multi-lug part, the process of the forging technology of the multi-lug part becomes easy, the production efficiency is improved, an air hammer and a roller forging
machine are not used any more, blank waste is reduced, and comprehensive benefits are improved.
