摘要
型材一次折斜角成形是航空零件制造工艺的重要方法之一。本文通过新研制的 5A90铝锂合金型材折斜角成形试验的研究 ,得到了极限开斜角和闭斜角值 。
Once-folding angle section craftwork is an important manufacturing technique in aircraft assembly parts?In this paper,the maximum folding angle of the 5A90 Al-Li alloy in forming process is found by forming test,that would give key data to newtype aircraft design and its forming process.
