Development of a complex optimizing model of wire drawing technology

The drawing of wires with round cross section is a widely used technological method for making a great number of wire products of different range of sizes with excellent material and surface quality. The planning of any kind of wire drawing technology is greatly facilitated by knowing the models describing the technological parameters in the best possible way. Mainly the finite element method (FEM) and the analytical method are used for modelling the above parameters. In constrast to FEM, the advantage of the continuous analytical models is that they require fewer calculation processes, which is a great advantage when planning the technology in industrial circumstances. In the course of planning, the choice of the individual technological parameters is determined by the cost effectiveness (i.e. the minimum specific energy consumption), the quality of products and the productivity. The aim of this research work was to determine and develop a complex optimizing target function for cold drawing technology that takes into consideration each of the above conditions. By utilizing the fast computability of an analytical model, design software meeting all the expectations and giving in-time results in industrial circumstances was developed by means of the complex optimization target function. © (2013) Trans Tech Publications, Switzerland.
