    摘要: An exemplary metal structure (10, 30) includes a base portion (14, 34), a flange (122, 322), and an edge portion (1241, 3241). The base portion defines a circular flanged hole (12, 32). The flange extends from a top surface of the base portion and the flange surrounds the circular flanged hole. The edge portion is configured for connecting an inside surface of the flange and the top surface of the base portion. The edge portion includes an edge surface, and a ratio of a radius of the edge surface (1242, 3242) of the edge portion with respect to a thickness of the base portion is less than 0.4. A method for making a circular flanged hole in a metal sheet (15) is also provided.

    摘要: An exemplary punch die (30) includes a lower die (40) and an upper die (50). The lower die includes a die core (45), a blank holder (417), and a cylinder (413) disposed in the lower die. The blank holder is disposed on a periphery of the die core. The cylinder is connected to the blank holder and provides a constant force to the blank holder. The upper die includes a punch core corresponding to the die core. A punch machine using the present punch die is also provided.

    摘要: A pad for portable electronics mounted on a housing of portable electronics is revealed. The pad includes a lower fastener, a buffer member arranged above the lower fastener, an upper fastener connected with the buffer member and mounted onto the housing, and a gripping member disposed above the upper fastener. The housing is arranged with an insertion hole. The gripping member penetrates the insertion hole and clips to a side wall of the housing. Thus there is no need to arrange the pad by adhesives or thermal fusion. Moreover, the height of the pad disposed is adjusted automatically by the buffer member. Therefore, the convenience of use of the pad is increased.
