Abstract
A die (10, 40) for extrusion of optical grade fibers includes an insert (12, 42) placed under compression within a sleeve (14, 44). Tapered surfaces (18, 20 & 48, 50) between the insert and the sleeve enable axial assembly of the components when the insert is forced within the sleeve. Lubrication and interlocking between the components comprise either general lubricant and an interlocking ring (30) residing within grooves (26, 28) in the tapered surfaces, or a metal (60) which provides first a lubrication during assembly of the components and then a metallurgical diffusion bond therebetween.
Claims9
A prestressed assembly comprising a sleeve, an insert housed in said sleeve, faces on said sleeve and said insert having a tapered interfacial contact in which said insert face, prior to the assembly of said insert in said sleeve, has a larger periphery than that of said sleeve face so that, after the assembly, said insert is placed under compression to urge slippage between said faces and ejection of said insert from said sleeve, and means interconnecting said sleeve and said insert at said contacting faces for preventing the slippage and the ejection.
A prestressed assembly comprising a sleeve, an insert housed under compression in said sleeve by means of faces on said sleeve and said insert having a tapered interfacial contact, and means interconnecting said sleeve and said insert for preventing slippage therebetween and comprising a metal between said faces forming a metallurgical diffusion bond therebetween.
