Method for attaching a contact element to the end of an electrical conductor
20180138648 · 2018-05-17 ·

A method for attaching a contact element to the end of an electrical conductor is specified, by which electrically conductive material which is present at the end of the conductor and is fixedly connected to the conductor is shaped to form a contact element with a variable shape. The end of the bare conductor is firstly moved into an at least approximately vertical position. Particles of an electrically conductive material are then applied at such a high speed to the upwardly projecting front-side end of the conductor in the axial direction thereof that the material of the conductor connects to the electrically conductive material to form a compact structure which is connected to the material of the conductor in a mechanically fixed and electrically conductive fashion. In order to form a metal body without interrupting the method, further particles of the electrically conductive material are subsequently applied to the compact structure, and the metal body is finally shaped mechanically to form the contact element.

WROUGHT METALLIC ARTICLE AND METHOD FOR MANUFACTURING THE SAME FROM A METALLIC-POWDER COMPOSITION

A method for manufacturing a wrought metallic article from a metallic-powder composition includes steps of: consolidating the metallic-powder composition to yield a consolidated preform having a cross-sectional area and a relative density of less than 100 percent; reducing the cross-sectional area of the consolidated preform via at least one forming pass of one of a cogging process and a rotary incremental forming process, thereby yielding an intermediate preform; and reducing the cross-sectional area of the intermediate preform via at least one forming pass of another of the cogging process and the rotary incremental forming process.
