摘要:

挤压成形是一种典型的大变形、复杂摩擦条件下的非线性高耗能成形过程,目前大多通过测量挤压力的方法推算其能耗值,由此造成了额外成本增加、设备干扰等一些问题。针对这些问题,提出了一种新颖的挤压能耗模型。以使用分流模的圆管挤压作为研究对象,首先根据挤压过程中金属流动特点,将挤压过程分为填充挤压阶段、基本挤压阶段和终了挤压阶段。然后根据各阶段的不同特点,以上限理论为基础建立能耗模型。最后以4种规格的圆棒挤压为例验证模型的准确性,同时采用实验设计(DOE)和方差分析(ANOVA)分析工艺参数对挤压能耗的影响。结果证明,所提出的模型能够有效计算圆管的挤压能耗,分析表明模具初始温度和挤压速度对挤压成形的能耗影响较为显著。

Extrusion forming is a typical nonlinear and high energy consumption process in the condition of large deformation and complex friction. At present, the value of energy consumption in the extrusion process is mostly calculated by measuring extrusion pressure, as a result, some problems such as additional cost and equipment interference are caused. For the above problems, a novel extrusion energy consumption model was presented. For a circulartube extrusion produced by porthole die, firstly, according to the characteristics of metal flow in the extrusion process, the extrusion process was divided into filling extrusion stage, basic extrusion stage and final extrusion stage, and then, an energy consumption model was established by the upper-bound theory according to different characteristics of each stage. At last, the accuracy of the model was verified by extruding four types of circular bar, and the influences of process parameters on the extrusion energy consumption were analysed by DOE and ANOVA methods. The results show that the proposed model can calculate the extrusion energy consumption of round tube effectively, and the initial temperature and extrusion speed of mould have a significant effect on the energy consumption of extrusion forming.
