摘要： The disclosure relates to method and tools for making shells used in the manufacture of can ends. A first set of tools makes blank pre-forms having a substantially flat central panel and an upward-extending chuckwall about the edge of the panel. The junction area between the panel and the chuckwall has a relatively large radius of curvature at this time. A second set of tools forms on the blanks a lip extending outward from the upper end of the chuckwall and generally parallel to said panel; then the panel and the chuckwall are separately gripped, followed by relative movement between the panel and the chuckwall while wrapping the junction area around a forming punch to form a panel wall in the junction area extending upward from the inner part of the chuckwall. Then the lip is formed into a curl edge section which ends in an inner curl diameter that is round and concentric with the chuckwall. Methods and apparatus are disclosed for (a) separating the pre-forms at the first tools and then transferring them individually to the second tools, or (b) partially separating the pre-forms at the first tools and using the advancing sheet metal stock to carry the pre-forms to the second tools. Also disclosed are various tool layout modifications for use in different types of single acting or double acting reciprocating presses.
摘要翻译：本公开涉及用于制造罐端部的壳体的方法和工具。第一组工具使空白预成型件具有基本上平坦的中心板和围绕板的边缘的向上延伸的夹板。此时，面板和夹板之间的接合面积具有相对较大的曲率半径。第二组工具在坯件上形成从吸盘壁的上端向外延伸并且大致平行于所述面板的唇缘; 然后分别夹紧面板和夹板，随后在面板和夹套壁之间的相对运动，同时将接合区域包围成形冲头，以在从夹套壁的内部向上延伸的接合区域中形成面板壁。然后，唇缘形成为卷曲边缘部分，该卷曲边缘部分以圆形并且与卡盘壁同心的内部卷曲直径终止。公开了用于（a）在第一工具处分离预成型件然后将它们单独地转移到第二工具的方法和装置，或（b）在第一工具处部分地分离预成形件并使用前进的金属板坯料携带预制表格到第二个工具。还公开了用于不同类型的单作用或双作用往复式压力机的各种工具布局修改。

摘要： The disclosure relates to a novel shell such as used in the manufacture of can ends, and to a method and tools for making such a shell. A non-circular blank having rounded corners is cut from thin metal. The blank is oblong in a direction transverse to the grain of the metal. A first set of tools separates the blanks and forms a substantially flat central panel and an upward-extending chuck wall about the edge of the panel to produce a partially formed shell. The junction area between said panel and said chuck wall has a relatively large radius of curvature at this time. A second set of tools forms in the blank a lip extending outward from the upper end of the chuck wall and generally parallel to said panel; then the panel and the chuck wall are separately gripped, followed by relative movement between the panel and the chuck wall while wrapping the junction area around a forming punch to form a panel wall in said junction area extending upward from the inner part of said chuck wall. Then the lip is formed into a curl edge section which ends in an inner curl diameter that is round and concentric with the chuck wall, and has progressively lesser radii of curvature from upper end of the chuck wall to the inner curl diameter. The resulting shell is characterized by a curl diameter being round and concentric with the chuck wall and essentially uniformly spaced therefrom, and by having an essentially constant thickness throughout the central panel, the panel wall and chuck wall and the curved section therebetween.
