    • The present invention relates to an apparatus and a method for forming bellows which can form a material tube manufactured by a material such as a stainless steel plate into bellows at once using multiple upper dies and lower dies to improve speed, to reduce labor force, and to improve productivity, so as to manufacture high-quality bellows. The apparatus for forming bellows comprises a rotating shaft rotatably installed at an upper part of a frame; multiple lower dies installed at the rotating shaft at predetermined intervals to be horizontally movable; an idling shaft installed at an upper part of the rotating shaft to be freely rotatable about a lifting/lowering means; and multiple upper dies installed at the idling shaft at predetermined intervals to be vertically movable, wherein the material tube horizontally coupled to the lower dies in a longitudinal direction is formed into bellows by the horizontal movement of the upper dies and the lower dies from the left or the right towards the center caused by the lowering of the upper dies. The time required for manufacturing bellows is remarkably shortened, thereby improving productivity; and the thickness of material can be uniformly maintained, thereby being able to manufacture high-quality bellows.
    • 本发明涉及一种用于形成波纹管的装置和方法,该装置和方法可以使用多个上模和下模一次形成由诸如不锈钢板的材料制成的材料管一次成波纹管,以提高速度,降低劳动力,以及 提高生产效率,制造高品质的波纹管。 用于形成波纹管的装置包括可旋转地安装在框架的上部的旋转轴; 多个下模以预定间隔安装在旋转轴处以水平移动; 安装在所述旋转轴的上部以能够围绕提升/降低装置自由旋转的空转轴; 和多个上模具以预定的间隔安装在空转轴上以可垂直移动,其中沿纵向方向水平联接到下模具的材料管通过上模具和下模具从左侧的水平运动形成波纹管 或者由于上模的下降引起的朝向中心的权利。 制造波纹管所需的时间显着缩短,从而提高生产率; 可以均匀地保持材料的厚度,从而能够制造高质量的波纹管。
