    • In order to provide a method and apparatus for forming a sheet metal, in which a three-dimensional product such as a prototype for commercialized press-forming can be formed in short time without limitations as to the shape and with high accuracy, preventing body wrinkles or reduction of the sheet thickness, a process of: performing drawing-forming to a predetermine height by pushing the forming punch having a desired shape in the sheet thickness direction with the edges of the blank workpiece being clamped; performing shape-forming with the shaping tool in the opposite side to the forming punch by increasing a clamping pressure to lock movement of a material with the forming punch being pushed; performing drawing-forming again by decreasing the clamping pressure and raising the forming punch by a desired height; and performing shape-forming with the shaping tool by increasing the clamping pressure to lock movement of a material, is repeated at least once.
    • 为了提供用于形成金属板的方法和装置,其中可以在短时间内形成诸如用于商业压制成型的原型的三维产品,而不限于形状和高精度,防止体皱纹 或减少片材厚度的方法;以下步骤:通过在坯料工件的边缘被夹持的同时将具有期望形状的成形冲头沿片材厚度方向推压到预定高度; 通过增加夹紧压力来与成型冲头的相对侧的成形工具进行成形,以锁定成形冲头被推动的材料的运动; 通过减小夹紧压力并将成形冲头提高希望的高度来再次进行拉伸成形; 并且通过增加夹持压力以锁定材料的运动,通过成形工具进行成形,至少重复一次。
