| 摘 要： | 板料数控渐进成形工艺是一种柔性的成形工艺,这种工艺非常适合于加工小批量、多品种和复杂的板料产品。通过数控机床进行圆锥台及直壁筒形件数控渐进成形,对成形零件变形区厚度进行测量,并对所得数据进行分析。试验结果表明,数控渐进成形中材料厚度变化遵循正弦定律。相同厚度的板料,材料不同,成形极限厚度不同。成形极限厚度不仅与材料有关,而且与板料初始厚度有关,即板料初始厚度越大,允许的变形区厚度减薄越大。对于必须采用多道次成形方法的直壁筒形件成形,工具路径不同,变形区厚度变化也不同。采用平行直线型工具路径,直壁部分厚度比较均匀。利用厚度变化规律指导翼子板成形并试验验证其正确性。厚度变化规律对于复杂零件的数控渐进成形具有一定的指导作用。
