基于正交试验的6063铝型材挤压成形工艺参数优化

Optimization of Extrusion Process Parameters of 6063 Aluminum Profile Based on Orthogonal Test

这篇文章以压块为例,对挤压过程的变形机理及工艺参数优化配比展开研究。压块作为固定幕墙与玻璃托的连接件,其质量的好坏直接影响玻璃的安全可靠性,而在压块的成形工艺中,金属材料内部晶粒尺寸的变化直接影响着压块的质量。为此,文章通过将有限元数值模拟分析方法与塑性成形理论相结合,以压块晶粒尺寸细化为目的,对挤压成形过程中的几个主要工艺参数进行优化,从而制定出最佳的工艺参数配比组合,为工厂的实际生产提供参考。

Taking the briquette as an example,this paper studies the deformation mechanism and the optimal ratio of process parameters in the extrusion process.As the connector between fixed curtain wall and glass support,the quality of pressing block directly affects the safety and reliability of glass.In the forming process of pressing block,the change of internal grain size of metal material directly affects the quality of pressing block.Therefore,by combining the finite element numerical simulation analysis method with the plastic forming theory,in order to refine the grain size of the briquette,this paper optimizes several main process parameters in the extrusion process,so as to formulate the best ratio combination of process parameters,and provide reference for the actual production of the factory.
