摘要
提出一种基于回收的磨损尺寸胀修恢复技术 ,并分析了胀修恢复后零件的残余应力分布 .根据理想弹塑性厚壁圆筒理论 ,在零件的原始设计中预留胀修恢复几何结构 ,当某些贵重零件的外径关键尺寸因磨损而失效后 ,通过胀修恢复技术把它胀大到预定值 ,使之恢复到设计公差范围内 .胀修恢复技术具有成本低、无污染、劳动强度小、不改变零件的表面形貌等优点 。
An elastic-plastic restore technology of abraded dimension for recycling was developed, and the part's residual stress distribution was described. According to the elastic-perfectly plastic thick cylinder theory, the key outer dimension of some expensive parts can be regained by its elastic-plastic deformation, which could expand this dimension into the preset value and restore it to within the tolerance range. This kind of key outer dimension recovery technology has many advantages, such as low cost and work intensity, little pollution and unchanged part's surface topography during the recovery process. Meanwhile the service life of the part would be protracted and its use-cost reduced.
