IMPACT OF DRAWING PROCESS PARAMETERS ON UNIFORMITY OF STRAIN IN SPRING WIRE

Popis výsledku v původním jazyce

Shear deformation of subsurface layers in wire drawing leads to marked non-uniformity of strain across the wire cross section. In wires intended for products operating under dynamic loads, such as ropes and springs, the variance in work hardening level across the cross section may cause fatigue fractures. <In this paper we used mathematical modelling in an attempt to show how the non-uniformity of strain in drawing can be reduced by changing key process parameters. For this purpose, a full factorial experiment involving three factors was undertaken. (The factors included the approach angle 2?, friction coefficient ? and single pass strain Qd or the number of passes n.) The simulation involved drawing of 2.5 mm C75 steel spring wire from 5.5 mm thick rolled rod. FormFEM 1.6 simulation software was used for the modelling. For the purpose of this experiment, the strain non-uniformity is defined as the difference between the maximum (normally on or just below the surface) and minimum (in t
