    • Various methods and devices are disclosed for shaping/embossing thin-walled work pieces (e.g., drawn and ironed container bodies having a sidewall thickness of no more than about 0.007). One aspect is particularly apt for realizing complex and non-uniform shapes/designs in cylindrical metal container bodies (40) applying at least one high velocity fluid stream (30a, 30b, or 30c) directly against one side of container body sidewall (45) with a configured surface (18) provided on the other side of the container body sidewall to achieve the desired shaping/embossing. Another aspect utilizes multiple fluids where one fluid applies a generally low fluid pressure to the surface to be reshaped and another fluid applies a generally high fluid impact pressure to the surface to reform the same by changing its shape. Yet another aspect relates to necking a container body (878) by applying at least one high velocity fluid stream to the exterior surface (896) of the container body (878) to reduce the diameter of its open end (890).
    • 公开了用于成形/压花薄壁工件(例如,具有不超过约0.007的侧壁厚度的拉制和熨烫的容器主体)的各种方法和装置。 一个方面特别适用于在圆柱形金属容器体(40)中实现复杂且不均匀的形状/设计,所述圆柱形金属容器主体(40)直接将容器主体侧壁(45)的一侧直接施加至少一个高速流体流(30a,30b或30c) 具有设置在容器主体侧壁的另一侧上的配置表面(18),以实现期望的成形/压花。 另一方面使用多种流体,其中一种流体对待重新形状的表面施加通常较低的流体压力,另一种流体通过改变其形状而将大体上高的流体冲击压力施加到表面以对其进行改性。 另一方面涉及通过向容器主体(878)的外表面(896)施加至少一个高速流体流来缩小容器主体(878)以减小其开口端(890)的直径。
