Bending of Thin Walled Pipes Using the Heat Realised by Friction

Abstract

This paper considers appliance of heat generated by friction to relieve deformation of light metals, having as example of bending thin walled copper pipes. Based on numerous, primarily experiment analysis the conclusions have been applied for designing a machine for bending of thin walled copper pipes having small bend radius. The machine’s design is relatively simple, but it provides realisation of needed temperatures within required narrow area. Large number of tests has shown the reliability of suggested methodology.
