| Abstract: | The forming experiments of a three dimensional, saddle shape curved surface were carried out on a multipoint die. The limit and rebound values of a L2Y2 aluminium sheet at various thicknesses were obtained during forming process. The influencing factors on forming limit and rebound were analyzed. The results showed that progressive forming was an effective measure to improve forming limit value in a multipoint molding process and repeatedly forming and increasing force in an adjacent area were efficient to obtain a desirable dimension of a forming object. |
