Technological design of the single-part production of former
Svoboda, Lukáš ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
This dissertation in the engineering study of the Engineering technology deals with the proposal of the unit production technology of two pieces of the tool for cold forming of the material X 45 NiCrMo 4, standard W. Nr material number 1. 2767. The production is on the demand and is therefore trial, because the specified tool has not been till now fabricated. The thesis describes an analysis of manufactured components, as well as a description of the material used, a description of the available technologies that were used and a design of production technology. The production will include these methods: turning, grinding, electro erosive deepening and polishing.

Proposal of production technology of trough
Rérych, Pavel ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
Elaborated thesis presents a proposal of technology for the production of modular. The modular is manufactured by ACO Industries k.s. from stainless steel 17 240 with thickness 1.5 mm. Literary studie is focused on Bending as the most favorable technology with respect to tender documentation. Based on technological calculations and available machinery TruBend 5130 press with nominal force 1 300kN was selected for part manufacturing process. Forming tools are made of Cr - Mo tool steal. The thesis also includes technical and economic evaluations.

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.
