TLDR
In this article, a pipe blank with constant cross-section shape and diameter is selected, which is larger than or equal to a minimum outer diameter of one section of the component to be formed, and has a crosssection that can be fitted inside that of the first section.Abstract:
The method involves selecting a pipe blank with constant cross-section shape and diameter, which is larger than or equal to a minimum outer diameter of one section of the component to be formed, and has a cross-section that can be fitted inside that of the first section. The wall thickness of the pipe blank is selected to be between or equal to the average wall thickness of one section of the component to be formed The precursor is arranged in the form die and hydroformed to manufacture the component. An Independent claim is included for a pipe-like component manufactured using the method.read more
