摘要
对于无芯棒开式冷挤压厚壁管件的相对伸长量的研究与预测是设计开式冷挤压管类零件及其专用设备的依据。本文通过对厚壁管件无芯棒开式冷挤压尺寸预测的实验研究,分析了影响相对伸长量的主要参数,找出了它们与相对伸长量之间的变化规律曲线,为指导实际生产提供了依据。
The research and prediction of relative elongation of thick-walled tube without mandrel by open-die cold extrusion is the base of the design of tube parts and special equipment. The main parameters influencing relative elongation are analysed by research on experiment of size prediction of thick-walled tube without mandrel by open-die cold extrusion, and their curves of changing rule are given, which applies reference in order to direct practical production.
