An Upper Bound Approach for the Direct Drawing of Square Section Rod from Round Bar

  • Chapter
Proceedings of the Twentieth International Machine Tool Design and Research Conference

Abstract

A theoretical approach is presented for the analysis of the direct drawing of square section rod with various corner radii from round bar. In the past a theoretical approach to this operation has rarely been attempted.

The mechanics of the cold drawing of the square rod have been examined by an upper bound approach which enables the calculation of the drawing force from the known geometry of the die and the mechanical characteristics of the workpiece.

This calculation must be considered as the first step towards a CAD/CAM of sectional drawing of more complicated shapes.
