高方盒形件的拉深变形比较复杂,当前又缺少简单可靠的设计依据。国内外现有的工艺过程设计方法,不仅计算繁复,而且可靠性不大,经常导致设计的失败。本文通过变形分析和利用高方盒形件成形极限图,得出简便易行的高方盒形件拉深工艺过程设计方法。 The drawing and deformation of the box-shaped parts of the upper part is rather complicated, and at present it lacks the simple and reliable design basis. The existing process design methods both at home and abroad are not only complicated to calculate but also less reliable, often leading to design failures. In this paper, through the deformation analysis and the use of the height of the box forming limit map, draw the simple and easy method of design box box deep drawing process.
