Showing papers on "Hydroforming published in 1986"
TL;DR: In this paper, an approximate solution is developed to include the influence of slight draw-in during the hydroforming of copper sheets into axisymmetrical shells, based on previous experimental observations and an earlier discussion on the effect of die shoulder radius.

TL;DR: In this article, the authors deal with the forming of zirconium from semi-finished products, forming limit curves for deep drawing, hydroforming, and isostatic forming; the weldability of large size zirconsium, components outside the glove-box, influence of structural modifications on mechanical properties; and the design of heterogeneous joints required for connection to the austenitic stainless steel pipes.
Abstract: The procedures employed in irradiated fuel reprocessing installations have led to the use of zirconium for the fabrication of certain components because of its excellent behavior in nitrate solutions. This paper deals with (1) the forming of zirconium from semi-finished products, forming limit curves for deep drawing, hydroforming, and isostatic forming; (2) the weldability of large size zirconium, components outside the glove-box, influence of structural modifications on mechanical properties; and (3) the design of heterogeneous joints required for connection to the austenitic stainless steel pipes.

TL;DR: The central core 10-11 and each of the rings 20-21, 30-31 which carry the manoeuvring jacks 40-41 and which are intended to fold the ferrule 50-51 by approaching each other, are constituted by two parts which can be assembled in such a way that the whole of the hydroforming apparatus is capable of being mounted around a ducting or other element A whose ends are not accessible as discussed by the authors.
Abstract: The central core 10-11 and each of the rings 20-21, 30-31 which carry the manoeuvring jacks 40-41 and which are intended to fold the ferrule 50-51 by approaching each other, are constituted by two parts which can be assembled in such a way that the whole of the hydroforming apparatus is capable of being mounted around a ducting or other element A whose ends are not accessible. The bellows produced is finally trapped on the ducting A.
