Rational Drawing Condition Choices of Thermally-Treated Steel Spring Wire

Abstract

The computer-simulated normal stress distribution in the working zone of the draw die and the dependence of its magnitude on various drawing parameters is given. Derived from the data and previously developed procedures for the evaluation of the metal’s stress state in the deformation zone, the operative wire drawing sequence is analyzed and improved, which is focused on subsequent quenching and tempering. The industrial experiment results confirm the performance of the new drawing sequence during the fabrication of thermal-treated spring wire.
