OPTIMIZIATION OF HALF-ROUND WIRE DRAWING PROCES BY MATHEMATICAL MODELLING

Popis výsledku v původním jazyce

The paper deals with mathematical modelling of drawing of low-carbon half-round wire using finite element method. Specifically, it covers drawing of hot rolled round wire C9D with the diameter of 6.5 mm to obtain a semicircular cross-section with the height of H = 4.025 mm, width D = 5.8 mm and a rounding diameter of r = 0.2 mm. The drawing process consists of two passes. The shape of the wire after pre-drawing is characterized by the rounding diameter of R. It allows the material to flow more easily into small-diameter corners in the final pass. These products find their application particularly in automotive industry as control button stems in dashboards. The computer simulation was carried out using the software package Forge 2009? developed by French Transvalor. Rhinoceros 3D was employed for developing the objects used in Forge 2009?. The total of 5 variants of drawing of the half-round wire was explored. The variants varied in the rounding diameter R in the pre-drawing pass. The
