摘要
根据汽车前轴锻件的特点、技术条件与要求,分析了前轴辊锻工艺的难点,包括确定辊锻件图,选择毛坯尺寸,确定辊锻,典型截面特征孔型设计,计算前滑量并分析其对锻件长度的影响。本文以NHR前轴为例,进行了精密辊锻制坯工艺及模具设计的研究,设计出前轴制坯辊锻、预成型辊锻和终成型辊锻模具。
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.
