本研究旨在设计轴承毂之飞边几何形状，以应用于热锻制程中之自动移送系统。飞边的几何形状对金属流动、材料损失、锻造载荷、模具压力等都有重要影响，因此飞边的几何形状在热锻过程中至关重要，本文针对轴承轮毂热锻过程中飞边厚度和宽度的设计问题进行了研究，并考虑了最大模具压力。数值分析是通过商业S/W DEFORM。在数值分析的基础上，对热锻模飞边形状进行了重新设计，并进行了试验研究。根据实验结果，可以用自动传送系统生产轴承毂，而不会使模具寿命恶化。
The aim of this study is to design flash geometry of bearing hub to apply the automatic transfer system in hot forging process. The flash geometry is very important in hot forging process because the flash geometry effects on the metal flow, material losses, forging load, die pressure and so on. In this study, the problem of designing the flash geometry is studied with flash thickness and width considering the maximum die pressure to apply an automatic transfer system in hot forging process for bearing hub. The numerical analysis was conducted by means of the commercial S/W DEFORM. On the basis of numerical analysis the flash geometry of hot forging die was redesigned, and experiment was conducted. From the experimental results, it was possible to produce bearing hub with an automatic transfer system without any deterioration of die lifetime.
