中文摘要

摘要: 以某车辆铝合金座椅骨架为研究对象,设计其挤压铸造工艺方案,运用AnyCasting软件对铸件的挤压铸造充型、凝固过程进行模拟,预判缩孔、缩松缺陷的发生部位,分析缺陷原因。采用局部增压与建立补缩通道技术优化方案,消除了缩孔、缩松缺陷。研究表明,对铸件厚大部位反向局部增压,当增压压力为100 MPa,增压时间为0.5 s时,局部增压效果理想。应用优化方案生产铸件,得到铸件质量良好,无明显缺陷,铸态下铸件的抗拉强度达到271 MPa,伸长率达6.52%符合标准要求。

Abstract:The design of the squeeze casting process for aluminum alloy frame was carried out, and the filling and solidification process of squeezing casting was simulated to predict occurrence of porosity shrinkage defect. Origination of shrinkage porosities (holes) in squeezing casting aluminum alloy frame was described. By adopting partial pressurization and setting feeding channel, shrinkage defects in the aluminum alloy frame were eliminated. Through reverse local pressurization with pressure of 100 MPa for 0.5 s, partial pressurization effect exhibits desirable. The practical production reveals that the aluminum alloy frame has the desirable quality with absence of defects, where the ascast tensile strength and elongation reach 271 MPa and 6.52%, respectively, meeting requirements.
