Progressive development of metal ware manufacturing is closely connected with
implementation of technologies with integrated or combined operations. Continuous method of
wire deformational processing by drawing with bending and twisting was developed. Medium
carbon steel wire with 0.5 %C was used for the experiments. The results of simulation in
Deform-3D showed that distributions of tensile and compression stresses at combined
deformational processing are uniform along the deformation zone. Microscopic analysis of the
processed wire indicated that after combined deformational processing a homogeneous structure
is formed in the medium carbon steel wire. After tensile test, it was proved that combination of
drawing with bending and twisting allows ones to achieve the different combination of strength
and ductile properties of medium carbon steel wire with one diameter and carbon content.
Keywords: medium carbon steel wire; combined deformation; drawing; bending; twisting. |
