20080256781 | Joining method and joined unit - The present invention provides a joining method of metal plates, which can connect two metal plates without a projection in a surface of the metal plates and a gap, and a joined unit having metal plates which are connected without a projection in a surface of the metal plates and a gap between the metal plates. The joined unit has a pair of metal plates. One of the metal plates has a hole, and another metal plate has a projection having a height less than a thickness of the one of the metal plates. The projection passes through the hole, the one of the metal plates is placed on the other of the metal plates each other, and a central part of an end surface of the projection is crushed in the hole. Thereby, the metal plates are joined to each other, and the joined unit can be provided. | 10-23-2008 |
20090068399 | Composite metal sheet, method for joining metal sheets, and device for joining metal sheets - It is an object of the present invention to provide a composite metal sheet having remarkably enhanced electrical property and reliability, a method for preparing the same composite metal sheet, and a device for preparing the same composite metal sheet. Specifically, the present invention provides a composite metal sheet produced by joining two metal sheets together, comprising: a projection formed by cutting the two metal sheets along a cutting line and pressing an area surrounded by the cutting line and a reference line in the two metal sheets, with the two metal sheets overlapping each other, with the reference line remaining uncut, with the cutting line extending from and communicating with both terminals of the reference line while forming a predetermined shape together with the reference line, and with the projection formed at one portion of the area in response to pressure applied to the area; hole generated by forming the projection in the two metal sheets; and a joint disposed between an outer peripheral cutting face of the projection and an inner peripheral cutting face of the hole. | 03-12-2009 |
20110076510 | Metal joint body and apparatus for manufacturing the metal joint body - A miniaturized metal joint body and an apparatus for manufacturing the metal joint body to be improved about strength are provided. By cutting three overlapped metal sheets along a first cutting line and a pair of second cutting lines extending so as to intersect the first cutting line at each end of the first cutting line and pressing areas surrounded with the first cutting line and the pair of second cutting lines and each of a pair of bending lines connecting both ends of the pair of second cutting lines, each of the pairs of projecting members is formed so as to project in a pressing direction of arrow Z. | 03-31-2011 |
