【 摘 要 】

In this work the influence of the die approach and bearing part of die on mechanical-technological properties of high carbon steel wires has been assessed. The drawing process of φ5.5 mm wires to the final wire of φ2.9 mm was conducted in 6 passes, by means of a multi-die drawing machine Koch type. The drawing speeds in the last passes were: 7 m/s. For wires drawn according to four variants the investigation of mechanical-technological properties has been carried out, in which yield strength, tensile strength, uniform and total elongation, reduction of area, the number of twists and the number of bends were determined. On the basis of numerical analyses wire drawing process, the influence of geometry of die on redundant strain and effective strain has been determined.
