Rolling Process of Ribs with Triangular Cross Section on Surface of Copper Tube

Abstract:

Article Preview

Ribs with triangular cross section can be obtained by rolling process on copper tube surface. The ribs are the basis for machining 3D Integral External Finned Tube. Triangular ribs on a red copper tube with 12.6mm diameter and 1.25mm wall thickness are fabricated under, the feed rate of 0.15mm/r, the speed of 2m/min, and rolling depth from 0.1mm to 0.85mm.In this study, four kinds of ribs are obtained. After the analysis of the relationship between rolling depth and the rib structure, the optimal single triangular rib can be obtained on condition that the rolling depth is 0.75mm.
