摘要: A tool for hot forming and press hardening a steel structure includes an upper tool and a lower tool, each having a base body made of highly heat conductive material and comprised of at least two segments. The base body of at least one of the upper and lower tools has a cooling channel. Arranged on the base body of at least one of the upper and lower tools is a wear protection shield.

摘要: A manufacturing method for a diamond coil for a rotating electric machine comprises bending a straight conductor in a first plane at eight points so as to produce coil leads, coil ends, and coil straight portions. The conductor is next twisted about its longitudinal axis so as to bend the coil ends out of the first plane. The conductor is then bent in two in a second plane, which is perpendicular to the first plane and which includes the longitudinal axis of the conductor, until the two leads of the conductor point in approximately the same direction.
