| Abstract: | According to the characters, technological condition and requirements of automotive front axle forging, the processing difficulties of automotive front axle are analyzed, including the determination of roll-forging parts chart, selection of billet dimension, decision of roll-forging steps, special roller-shaped design of typical section, and the front sliding parameter is calculated, its effect to length of forging parts gets analyzed. In this paper, taking NHR front axle as an instance, both the process of exact roll-forging billet and die design are studied, as the result, roll-forging die of front axle billet, pre-completed roll-forging die and final roll- forging die are design respectively. |
