摘要
分析大型厚壁半球封头在整体热压成形时的主要成形缺陷和产生原因。根据企业长期生产经验,提出从合适的毛坯尺寸、压制温度、凸凹模间隙、凹模圆角半径以及成形速度等方面有效控制其成形缺陷。
Main forming defects and leading cause for large thick-wall semi-spherical head are analyzed during whole hot forming.According to long practical experience in enterprise,efficient control measures to solve its forming defects are provided,such as right blank size,foming temperature,clearance between punch and die,die circle horn radius,forming speed and so on.
