Optimization of Parameters of Diamond-Coated Dies for Cu Wire Drawing by FEM Simulations


Article Preview

Diamond-coated drawing dies are considered as ideal drawing dies for their unique characteristics, such as high hardness, wear resistance and low friction. In order to optimize the parameters of diamond coated drawing dies, this study conducts a finite element method (FEM) simulation to calculate the von Mises stresses distribution on the interior-hole surfaces of diamond coated drawing die during the copper wire drawing process, and then refines the diamond coated drawing dies based on the simulation results. Furthermore, the drawing performance of the optimized diamond coated drawing die is examined in a real production of drawing copper wires, and the results show that its working lifetime increase by a factor of 12 comparing with the conventional tungsten carbide drawing die.
