Abstract
According to the characters, technological condition and requirements of automobile front axle forging piece, the processing difficulties of automotive front axle are analyzed, including the determination of roll- forging piece graph, selection of blank size, decision of roll- forging pass, 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, blank-making roll- forging die of front axle, pre-molding roll- forging die and final forming roll-forging die are design respectively.
