【摘要】：复杂曲面零件成形一直是诸多学者的研究热点,为了提高复杂曲面零件的成形性能以及壁厚均匀性.以铝合金异形底盒形件为研究对象,采用预胀的充液拉深技术对5A06铝合金盒形件进行数值模拟,探索预胀压力和预胀高度等参数对异形底盒形件成形的影响规律,分析成形过程中控制参数变化对零件成形性能以及壁厚分布的影响.当预胀压力为8 MPa,预胀高度为12mm,液室压力为20 MPa以及压边间隙为1.03 mm时为本模型的最合理方案.为异形底盒形件充液拉深成形的工艺参数的制定提供了参考以及对复杂零件成形的工艺分析具有一定指导意义.
[Abstract]:The forming of complex curved surface parts has been a hot spot of many scholars, in order to improve the forming performance and the uniformity of wall thickness of complex curved surface parts. Taking aluminum alloy special-shaped bottom box-shaped parts as research object, numerical simulation of 5A06 aluminum alloy box-shaped parts was carried out by means of pre-expanding liquid-filled drawing technology, and the influence of pre-expansion pressure and pre-expansion height on the forming of special-shaped bottom boxes was explored. The influence of controlling parameters on forming performance and wall thickness distribution during forming process is analyzed. When the pre-expansion pressure is 8 MPa, the height of pre-expansion is 12 mm, the pressure of liquid chamber is 20 MPa, and the clearance of blank holder is 1.03 mm, it is the most reasonable scheme of this model. It provides a reference for the formulation of the process parameters of the liquid-filled deep drawing of the special-shaped box-shaped parts and has a certain guiding significance for the process analysis of the forming of the complex parts.
