Wire Drawing Technology
Štys, Michal ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
The paper presents current research on the technology of wire drawing with focusing on the analysis of process factors, their calculation and influence on the process itself. The research describes drawing methods and technological process of wire drawing. The work also deals with geometry and die materials and their effects on process quality and tool wear. Subsequently this thesis analyses currently used machines and their advantages and disadvantages. As well as their suitability for use depending on the materials of the drawn wires and economic profitability. At the end of the thesis, unconventional methods of wire drawing and their future development estimation are presented.

Design of tool for drawing of wire
Kryštof, Marek ; Lidmila, Zdeněk (referee) ; Císařová, Michaela (advisor)
This thesis submits design of tool for drawing wire. The wire is using like a semi-finished product for production of steel abrasive brush. Based on a literary study and calculations, the drawing tools were designed according to the attached documentation. The starting blank for drawing was chosen stainless steel wire made of 1.4301 steel (ČSN 17 240) with a diameter of 1.2 millimeters. The production procedure is designed for the KOCH KTZ II/17 towing machine. The wire is drawn in seventeen operations.

Optimizing of die geometry for wet drawing of a steel wire with process fluid
Bršťák, Ondřej ; Zmrzlý, Martin (referee) ; Píška, Miroslav (advisor)
The subject of this diploma thesis was both the analysis of the wire drawing process and the design of a new drawing die. All tests were performed at real production line. The primary aim of the analysis was the change in the current lubricating medium. Based on the performed analysis the test was developed to determine the exact values of the friction coefficient of the new lubricant. In the following part of the thesis the wire manufacturing process was described with a focus on the performance of the drawing die. For that matter material tests were performed and a material model was developed and then used for further calculations. Based on the results the geometry of the drawing die was changed and hence the drawing process was optimized with the focus on both increasing the lifetime of the drawing die and maintaining the complexity of the production. First drafts of new drawing dies were created and cost savings were calculated. In the last section the next modifications were proposed to increase the lifetime of the drawing dies.
