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.

Productin of injector holder
Štys, Michal ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
This paper presents a design of the production process for the clamping nut by cold extrusion. The nut, which is made of material ČSN 12 050, is used to clamp the injection nozzle to the injection system. Subsequently different variants of production were processed, from which the variant B was chosen. For slug a rod with diameter size of 24 mm with toleration f9 made by the company Ferona a. s was chosen. Calculations of process parameters were made for this variant. Based on the parameters the automatic forming machine TPD 630 with nominal force of 6 000 kN was chosen. For the selected machine, operational tools were designed for each forming operation, whose geometry is shown in the drawing documentation. Based on the technical and economical evaluation, the final price of the formed part was set at CZK 18,48.
