A study on influences of some process parameters on cold drawing of ferrous wires

Abstract

Wire drawing process involves pulling metal wire road through a die by means of a tensile force applied to exit side of die. This paper is an experimental study that presents influences of some parameters like deformation (total reduction) ratio and drawing speed on cold drawing of ferrous wires. Wire drawing method is applied to C45, C63, C65 and C70 materials for different deformation ratios and different drawing velocities. Subsequently, these process influences are considered by means of tensile and torsion tests.  With these investigations, it can be simply observed that the deformation ratio and drawing speed parameters clearly affect tensile and torsion strength (number of twist) of ferrous materials. In addition to these observations, from the results of experiments it can be concluded that C content is also effective on tensile and torsion strength of steel wires. Finally, tensile strength and twist number values are obtained for C45, C65 and C70 wire material as functions of drawing speed and deformation (total reduction) ratio by using the statistical analysis from the experimental data.
