摘要:
依据工艺试验所得数据,采用有限元软件对铝棒材挤压成形过程的温度场进行了数值模拟,得出了反映该过程温度场分布和变化情况的云图,并结合实验研究和模拟结果对其工艺规律进行了深入分析.研究结果表明:保压时间是决定工艺稳定性和制件质量的重要工艺参数,合适的保压时间可使挤压过程中变形区金属始终处于半固态,保证工艺的顺利实施.该结论为进一步设计优化工艺参数提供了理论依据.
Abstract:
According to the data obtained from the process test, the temperature field of the aluminum bar extrusion forming process was numerically simulated by finite element software, and a cloud map reflecting the temperature field distribution and change of the process was obtained, and the process law was analyzed in depth based on the experimental research and simulation results. The results show that the holding time is an important process parameter that determines the stability of the process and the quality of the parts, and the appropriate holding time can make the metal in the deformation zone in the extrusion process always remain semi-solid, which ensures the smooth implementation of the process. This conclusion provides a theoretical basis for further design and optimization of process parameters.
