Optimal Design of Combined Cold Extrusion Concave Die with Oblique End Face

摘要

Through the contrast analysis of optimal design of the flat and the oblique end face combination concave die which can be know the stress distribution of the combined concave die of the bicycle teeth steel bowl. It points out that the combined concave die with oblique end face can make the size on the structure of the die smaller and the structure more compact under the same internal pressure. At the same time, it provides reference to the structure optimization design of bearing partial pressure or irregular thick cylinder combination concave die.
