摘要
介绍了金属板料数控渐进成形工艺的成形原理、变形分析、直壁筒形件成形的工具路径设计、实验条件及结果分析。根据正弦定律 ,金属板料数控渐进成形工艺 ,不能一次成形出直壁筒形件 ,要成形直壁筒形件 ,必须进行多次成形。为了尽快逼近直壁筒形件 ,设计了平行直线型等三种工具路径方案 ,通过实验和结果分析 ,找到最佳方案。
The forming principle, deformation analysis, the tool path design, the experimental condition, and the result analysis of vertical wall cylinder forming in NC incremental sheet metal forming process are presented. According to the sine law, vertical wall shell cannot be finished at one time in NC incremental sheet metal forming process, it must be formed at many times. Thus, three process methods are presented to make vertical wall shell parts quickly, and experiment and analysis are made to verify it.
