Abstract

Conception of Hollow Axles Forming by Skew Rolling with Moving Mandrel

Highlights

  • Hollow axles and shafts are increasingly common in automation and machine industry, due to the fact that their mechanical properties are comparable to the ones of solid elements, while offering a significantly lower mass

  • This paper presents a new concept of skew rolling large-size hollow axles in a CNC rolling mill

  • The deformations are placed annularly, with the greatest values located in the outer layers and the greatest in the inner ones. Such a distribution is caused by the rolls causing intensive material flow in the tangential direction. Such a distribution is typical for skew rolling processes [19]

Summary

Introduction

Hollow axles and shafts are increasingly common in automation and machine industry, due to the fact that their mechanical properties are comparable to the ones of solid elements, while offering a significantly lower mass. ABSTRACT The article presents a conception of manufacturing a hollow axle using three skewed rolls moving at the same rotating speed, axially moving chuck and a moving mandrel. The first attempts at rolling full rail axles in 1:5 scale in laboratory conditions confirmed another benefit of this process, that is relatively small (compared to the dimensions of the workpiece) values of forming forces and torque.
