摘　　要：以高压开关用触头座的温挤压为例,分析了摩擦系数、模具下压速度、坯料外径尺寸对纯铜温挤压成形性能的影响。基于MATLAB软件中的MBC(model-based calibration)工具箱建立了工艺参数(摩擦系数、模具下压速度、预成型件外径尺寸)与目标函数(成形载荷、最大损伤值)之间的数学模型,并借助于MBC工具箱中的CAGE优化模块对目标函数进行多目标优化,得到最佳的工艺参数组合,即摩擦系数为0.34,坯料外径尺寸为83.5 mm,模具下压速度为30～40 mm/s。生产实践结果表明多目标优化后的工艺参数能够获得形貌完整的触头座挤压件,并且能够有效地降低挤压件的成形载荷及最大损伤值,而且显著地提高了材料的利用率。Taking the warm extrusion of contactor socket used in high voltage condition as an example,the effects of technology parameters such as friction coefficient,speed of die pressing,billet size on the warm extrusion formabili- ty of pure copper are analyzed.A mathematical model is established by taking the process parameters (friction coeffi- cient,speed of die pressing,billet size)as variables while the simulation results (forming load,maximum damage) as responses,based on model-based calibration (MBC)toolbox in MATLAB software.The optimum process parame- ters are achieved by the CAGE optimization module in MBC toolbox,namely,the friction coefficient is 0.34,the bil- let diameter is 83.5mm,the speed of die pressing is 30~40mm/s.Production practice shows that the process parame- ters after multi-objective optimization can get contactor socket without any defects on surface,what is more,it can re- duce the maximum damage and forming load effectively,the utilization of material is also improved obviously.
