【摘要】 针对半圆管直径为Φ100 mm、弯头弯曲半径为R100 mm的小半径半圆管弯头的成形加工,由于其弯曲半径过小,而无法采用传统管弯头弯制方法成形。经过工艺分析和理论计算,设计了弯曲成形模具和坯料,并通过弯曲实验优化了模具结构和坯料,避免了变形过程中起皱、拉裂等问题,通过控制回弹在合理的范围内,生产出了合格的半圆管弯头。更多还原

【Abstract】 The diameter of semi-round pipe is Φ100mm.Bending radius of semi-round elbow is R100mm.It is too minor to adopt traditional way of elbow forming.The bending dies and billets were designed through analysis and theory calculation.The structure of dies and billet was optimized through bending experiment.The wrinkle and cracks were avoided.The spring back was controlled.The regular semi-round elbow was made out.更多还原
