摘要
采用有限单元法,基于SLJB630型连续挤压机,对直径150 mm×2.8 mm电缆铝护套的连续包覆成型过程进行有限元分析,分析了成型过程中变形金属速度场、温度场、应力场和应变场的分布规律;进行了150 mm×2.8 mm电缆铝护套的连续挤压工艺实验,产品成型良好.模拟结果与实验结果对比分析,具有一致性,证明所建立的有限元模型准确,可以作为大管径电缆铝护套模具优化设计的理论依据.
Using finite element method, the continuous extrusion process of cable SLJB630 Konform machine was numerically simulated. The velocity, temperature, stress aluminum sheath on and strain fields were observed. The Ф150 mm × 2.8 mm cable aluminum sheath was produced. The simulation result and the experiment data fits well, which proves that the FE model is precise, and it can be used as a theoretical guidance for die optimized design of big size cable aluminum sheath.
