Evaluation of the Tooling Design for the Production of Large Diameter - Thin Wall Tubular Shapes. by Hydrostatic Extrusion.
Abstract
A multi-phase program was initiated for the development of a prototype-production process for manufacturing large diameter, thin-walled tubular ordnance items by hydrostatic extrusion. The ASROC missile case was selected as a component representative of such naval ordnance items. The full-scale tooling design concepts developed in Phase II(a) were modified and adapted to fit in Battelle's deven-inch bore hydrostatic extrusion container. The tooling design was then evaluated by extruding approximately half-scale cases from 6061 aluminum, AISI 1015 and AISI 4135 steel. Evaluation of the extruded products indicated that the dimensional requirements of the full-size ASROC could be achieved by hydrostatic extrusion. An economic analysis indicated that the estimated production cost for a full-size ASROC motor case could be reduced as much as 18%, based on quantities of 500, to 24%, based on quantities of 10,000, if produced by hydrostatic extrusion instead of shear forming.
