AXIAL LOADS ACTING ON MANDRELIN COPPER RIFLED TUBE DRAhVING PROCESS
(Depurtment of Materials Science and Engineering，Central South University of Technology，Changsha 410083)
Abstract: Stresses and axial loads acting on the mandrel in the copper rifled tube drawing process were analysed，and factors affecting on the axial loads on mandrel were discussed. Results show that the depth of the mandrel dragged into sizing zone and lubrication have major influence on drawing loads and fin shapes.
Key words: drawing copper rifled tube lubrication fin
