Abstract
It is an analytic investigation of issues related to improving the efficiency and reliability of the drawing technological process, which are to be considered. After analytical efforts, a technical solution is proposed and justified. This technical solution is meant to improve the operational parameters of the cable products current-carrying conductor – reducing electrical resistance by reducing the fractional deformation and recalculating of the drawing sequence.
Highlights
Wire-drawing operations are the beginning of the manufacturing technology for all types of cableconductor products (CAT)
Efficiency improving of the drawing technological process may be achieved by using modern production lines in the production process, combining several technological operations; using so called multiwire drawing, when 8 until 56 wires are simultaneously being drawn; reduction of power consumption by technological equipment; the choice of the optimal parameters of the emulsion; service life extension of the technological tool - wire-drawing die; using high-quality die billets; improvement processes of technologies and modernization of equipment with the introduction of resource-saving and energy-saving electromechanical systems (EMC) [4, 8]
An analytic investigation of the methods which have been used to increase the efficiency of modern drawing machines (DMs) made it possible to conclude that the joint influence of factors to improve the quality of the drawn wire and simultaneously increase the energy and resource saving of the drawing technology cannot be solved at the same time
Summary
Wire-drawing operations are the beginning of the manufacturing technology for all types of cableconductor products (CAT). This technical process provides a production of high-quality cable conductors [1]. All basic research in the field of increasing the reliability and efficiency of drawing technologies [2, 3, 4] led to the conclusion that the solution of the problems existing for the current production is provided mainly by technical re-equipment of enterprises, by equipping the production process with advanced technological equipment and modernizing the installed plant and equipment. An ultimate goal of the manufacturing process is to provide high operational characteristics of the technical checkpoint, including the low value of the electrical (true ohmic) resistance of the current-carrying conductor (CCC). A well-established drawing technology, as an initial technological operation, has the greatest influence on the process of formation of the structure of the current-carrying conductor
