| 摘 要： | 时效成形是解决整体高筋壁板成形、提高零件制造精度和使用寿命的有效工艺方法,但由于具有回弹量大,且模具型面难以确定和修正的特点,限制了其在国内工程化的应用。该文针对小曲率、小变形整体壁板的时效成形,通过时效成形基础试验,研究其回弹规律,并应用几何补偿算法,进行模具型面的回弹补偿计算。实验验证表明,零件外形曲面误差小于1mm,筋条处的误差小于0.5mm,证明该回弹规律及补偿算法具有有效性和准确性。

| Abstract: | Age forming,an effective technique,aims at solving the forming of the high flange integral panels,improving the manufacturing precision of the parts and its service life.However,the characteristics of huge amount of springback and the difficulties in determining and modifying the shape of mold surface limited its engineering application at home.Directing against the age forming of the small curvature and the small deformation of the integral panels,the springback rules was studied through the fundamental ex... |
