A three-dimensional analysis of the effect of die body deflection in the design of extrusion dies

摘要

Flat extrusion dies operating under high pressure often experience a significnat amount of distortion.Satisfactory designs of such dies require an accurate an accurate predication of the deflection of the die body as well as the flow in the internal channels of the die.Here a three -dimensional deflection analysis is coupled to a three-dimenisonal flow analysis.Such analyses are now being used by design engineers on personal computers for routine design of deflecting dies.
