摘要：

针对大壁角深腔类零件成形难的问题，在分析平行直线、平行弧线和变角度多道次双面渐进成形的基础上，提出了一种“Z”形折线连续多道次双面渐进成形策略。以大壁角深腔类方锥为研究对象，通过有限元模拟结果得出，“Z”形折线连续多道次双面渐进成形策略在平均厚度和几何偏差上表现优越。并通过试验验证了“Z”形折线连续多道次双面渐进成形策略的成形效果。结果表明，“Z”形折线连续多道次双面渐进成形策略得到了更为均匀的厚度分布，平均厚度由0.78 mm提升为0.87 mm，厚度减薄率与变角度多道次双面渐进成形相比提高了7％，显著提高了双面渐进成形工艺中大壁角深腔类试验件的成形精度和表面质量。

Aiming at the problem of difficulty in forming deep cavity parts with large wall angle, based on the analysis of parallel straight line, parallel arc and variable angle multi-pass double-sided incremental forming, a Z-shaped polygonal continuous multi-pass double-sided incremental forming strategy was proposed. Then, for deep cavity square cone with large wall angle, it was obtained by finite element simulation that the Z-shaped polygonal continuous multi-pass double-sided incremental forming strategy performed well on the average thickness and geometric deviation, and the forming effect of Z-shaped polygonal continuous multi-pass double-sided incremental forming strategy was verified by experiments. The results show that the more uniform thickness distribution is obtained by Z-shaped polygonal continuous multi-pass double-sided incremental forming strategy, the average thickness is increased from 0.78 mm to 0.87 mm, and the thickness reduction rate is increased by 7% compared with the variable angle multi-pass double-sided incremental forming, the forming precision and surface quality of deep cavity specimens with large wall angle in double-sided incremental forming process are improved remarkably.
