—In wire drawing, instability of the deformation parameters produces variable axial stress. The contact friction changes within an extremely short period and depends on many factors, such as the uniformity of the workpiece’s physicomechanical pro

Relations are established between different shape variables of the deformation region when a circular profile is drawn through a conical drawplate channel. The axial stress and optimal drawing angle are determined as function of the shape variables o

Analytical formulas are proposed for calculating the axial stress and optimal working channel of the die for two models of the strain hardening of nonhollow circular rod. The hardening curve must be taken into account in calculating the stress state

The drawing of 12X18H10T stainless-steel wire with a cupronickel coating and cadmium-plated carbon-steel wire is considered. The quality of zinc-plated carbon wire is shown to depend on the drawing temperature, which must be stable.
