    • PROBLEM TO BE SOLVED: To provide a hoop forming method which can be automated even in a structure having a plurality of forming portions. SOLUTION: Terminals 12 and terminals 18 formed inside a frame portion 30 so as to form a line in the direction of the width of a hoop material 14 are displaced toward the base portion 20 side of the terminals 18 after bending the terminals 12. Therefore, even when the terminals 12 in the developed state are set so as to be longer than the distance from the connecting portions for weak portions 34 and connecting portions 32 to the base portion 20, the tip ends of the terminals 12 can be formed at the position so as not to overlap with the base portion 20 and the terminals 18. Further, the hoop material 14 has the terminals 12, 18 formed thereon, and a hoop material 24 has terminals 22 formed thereon. The terminals 22 and the base portion 26 are placed in the same state as that formed in the hoop material 14 by integrally connecting caulking pieces 48 connected to the terminals 22 punched from the hoop material 24 to caulking pieces 38 of the hoop material 14. By this configuration, the work for independently preparing the terminals 12, 18, 22 beforehand and for arranging them in a resin forming die becomes unnecessary. COPYRIGHT: (C)2006,JPO&NCIPI
    • 要解决的问题:提供即使在具有多个成形部分的结构中也能够自动化的环形成形方法。 解决方案:在框架部分30内形成的端环12和端子18,以在环形材料14的宽度方向上形成线,在端子12弯曲之后朝向端子18的基部20侧移动 因此,即使在显影状态的端子12被设定为比从弱部34和连接部32的连接部到基部20的距离长的位置,也可以形成端子12的前端 在与基部20和端子18不重叠的位置处。另外,环形材料14具有形成在其上的端子12,18,环形材料24具有形成在其上的端子22。 端子22和基部26通过将连接到从环箍材料24冲压的端子22的铆接片48整体连接到环箍材料14的铆接件38而与环箍材料14中形成的状态相同。通过 在这种结构中,预先用于独立地准备端子12,18,22并将其布置在树脂成型模具中的工作变得不必要。 版权所有(C)2006,JPO&NCIPI
