铝型材挤压模工作带的计算机辅助设计

本文提出了一个铝型材挤压模工作带的数学模型，该模型不仅反映了模孔形状对金属流动的影响，而且考虑了模孔位置的影响，根据该模型作者在ＣＡＤＤＳ５上开发了铝型材挤压模工作带的计算机辅助设计系统。实践表明，该系统设计的挤压模工作带能较好地平衡金属流出模孔的速度，减轻型材的歪扭，弯曲，波浪，裂纹等缺陷。

Computer Aided Design for Aluminium Extrusion Die Bearing

A mathematical model for aluminium extrusion die bearing is proposed in this paper.The section shape and die holes location that will influence material flow have been considered in this model Based on this model,computer aided design system of extrusion die bearing is developed.It has been proved that the die bearing designed by this system can balance material flow velocity that comes from die holes,so can reduce bent,crack,twist of extrudates.
