VERFAHREN ZUR HERSTELLUNG EINES STOSSDÄMPFERS UND ERHALTENER STOSSDÄMPFER

摘要

The method comprises providing a planar sheet part (110); forming said planar sheet part (110) by drawing or conical spinning to the shape of a partially formed part (120) made up of a plate (1) and a provisional hollow portion (2a) extending from said plate (1) with a revolution shape with respect to an axis (E) perpendicular to the plate (1), and an end wall (3) closing an end of said provisional hollow portion (2a) opposite to the plate (1); and elongating a section of the provisional hollow portion (2a) by cylindrical or conical spinning. The shock absorber (130) is integral with a plate (1) and an elongated hollow portion (2b) extending from the plate (1) with a revolution shape. A section of the elongated hollow portion (2b) has a thickness (Gf) that is thinner than the thickness (Gi) of the plate (1):
