METHOD AND MEANS FOR CLOSING TUBES BY SPINNING

Patent · 26 August 1958

OSTI ID:4262139

Graves, E E; Coonfare, R H

An improved spinning tool is described for producing a fold-free closed end on an aluminum jacketing tube such as is commonly used to protect a uranium fuel element. The tool will fit the toolholder of a lathe in which the jacket is rotated. The tool has a number of working faces so that the hemispherical end- closure is formed, the folds and wrinkles are smcothed out, and the excess metal is trimmed off in one transverse cutting operation. This tool considerably speeds up the closure process, and eliminates the need for a weld seal.
