摘　　要：研究了剪切旋压加热温度、进给率和半锥角对残余应力分布的影响规律。试验结果表明:旋压进给比增大,残余压应力减小;适宜的旋压变形温度范围有利于降低工件表面残余应力;半锥角对工件表面残余应力的影响不显著,5A06铝合金旋压适宜采用30°～45°的半锥角。The effect law of heating tempe-rature, feed rate and semi-cone on resudual stress dis- tribution after shear spinning process is studied. The results show that the residual compressive stress decreases when spinning feed ratio increases. Suitable spinning deformation temperature range is useful to reduce residual stress on the work piece surface. The effect of semi-cone angle on residual stress on the work piece surface is not significant, and semi-cone angle 30°-45° is suitable for the spinning of aluminum alloy 5A06.
