    • The invention relates to a method for shaping an essentially flat-surfaced blank (10) to form a shell body (34), comprising the following steps: forming at least one flat-surfaced, buckling-stable insert (12) which is adapted to form, dimension and deformation properties of the flat-surfaced blank (10); forming a blank (14) to be deformed and at least one buckling-stable insert (16, 16′, 16″) to be deformed from the flat-surfaced blank (10, 10′) and the at least one flat-surfaced buckling-stable insert (12, 12′); placing and clamping the blank (14) to be deformed and the at least one buckling-stable insert (16, 16′, 16″) relative to one another and deforming the blank (14) together with the at least one buckling-stable insert (16, 16′, 16″) to be deformed in order to form the shell body, using at least one forming tool (32) that acts upon the front or inner side (20) of the blank (14) to be deformed or the at least one insert (16) to be deformed which is provided as a support. The invention also relates to the use of said shell body (34) to produce rotationally symmetric and/or not rotationally symmetric shell-shaped components.
    • 本发明涉及一种用于成形基本上平坦表面的坯料(10)以形成壳体(34)的方法,包括以下步骤:形成至少一个平坦表面的弯曲稳定的插入件(12),其适于 平面坯料(10)的形状,尺寸和变形特性; 形成待变形的坯料(14)和要从平坦表面的坯料(10,10')变形的至少一个弯曲稳定的插入件(16,16',16“)和至少一个平坦表面的翘曲 - 稳定插入件(12,12'); 将待变形的坯件(14)和相对于彼此的至少一个弯曲稳定的插入件(16,16',16“)放置和夹紧,并使坯件(14)与至少一个弯曲稳定的插入件 (16,16',16“)进行变形,以便形成壳体,使用至少一个作用在坯料(14)的前侧或内侧(20)上的成形工具(32)进行变形,或 所述至少一个待变形的插入件(16)被设置为支撑件。 本发明还涉及所述壳体(34)用于产生旋转对称和/或不旋转对称的壳形部件的用途。
