Technology project for general production of the "PC-box cover"
Křivý, Drahoš ; Horák, Jaroslav (referee) ; Rumíšek, Pavel (advisor)
The project, which was done within the scope of engineering’s study shows the proposal of new technology and production organization of a part “PC cover” – a piece done by deep drawing technology from steel sheet of material 11 321. The study shows some of production operations such as cutting, bending, drawing and shearing, included production method solving. In the project were solved also necessary technological calculations and constructional drafts of forming tool. The whole work covers a complex solution of problems related to production of PC cover together with technological disposition of workplace which represents effective layout, distribution and designing of workplace and machines, used for production of the part in a workshop

The manufacturing of electrical set covering for halide lamp
Bezpalec, Jan ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
BEZPALEC Jan: The manufacturing of elecrical set covering for halide lamp. The project elaborated in frame of Bachelor's studies branch 2307. The project is submitting design of technology production of the extract from the deep drawing sheet iron 11 320.21. Based on literature studies campaign issue, with regard to the series 20 000 pieces, it was suggested drawing a conventional method. Extract is drawn to a single operation using the retainer.Drawing punch and drawing die are produced from alloyed instrumental steel 19 436.9 , heat-worked according to drawing documentation.

Influence of surface treatments on the quality of molded parts
Okurka, David ; Dvořák, Milan (referee) ; Hušek, Martin (advisor)
This thesis examines the influence of surface treatments on the quality of molded parts. At the beginning of this work explains why the finish and what are the current demands on the development of manufacturing technologies. It further describes the most common surface treatment of metals, which are currently very often occur. The next section is divided into forming the surface and volume and describes the different types of species-forming, such as cutting, bending, drawing, etc. At the end of the work described cooperation with the Hettich ČR, k.s. and Tokoz, a.s.

Productions of the bearing cover
Kopeček, Václav ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
KOPEČEK Václav: Production of the bearing cover . The bearing cover is product rotational shape used in a single-stage gearbox. It is made from material ČSN 17 247 with 60 000 per year in series. The most optimal option of production, which is proposed based on the literary study, is the technology of conventional draught with blankholder. A tool, punch and die were chosen due to performed technology and structural calculatios. And it was also determined the machine CTC 250 with nominal power 250 kN. It was fixed price 27 CZK for one piece from an economic evaluation.

Design of a forming machine for production of a stainless steel cup with follow die
Staněk, Michal ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
My dissertation describes the procedure and results of designing a single-purpose machine, which is designed for forming a stainless metal product from an initial semi-finished product. This semi-finished product is a 0.28mm-thick stainless-steel plate. The introduction of my dissertation outlines the evolution of the pulling technology in the Czech Republic and abroad and describes its further details. This research part also includes an overview of individual machines according to the CSN. The practical part is then further dedicated to the exploration of individual issues and requirements for designing the machine itself as well as designing the machine according to the requirements of the final pulled product.

Production single parts "COVER" from sheet metal
Vítek, Roman ; Císařová, Michaela (referee) ; Žák, Ladislav (advisor)
The Master’s thesis written in the frame of studies branch Manufacturing Technology (2303T002) is submitting design of technology production of sheet metal cover. The part is made of sheet metal 1,5 mm thick. The material for the part is HC260LA (ZStE260). There are no special mechanical or dimensional accuracy demands for the part. According to production run (5 000 pcs. per year for 5 years), design complexity and machine accessories of submitter was proposed manufacturing the part by drawing technology with finish laser cutting. Forming tool is designed according with press Erfurt PKZZ 315. Thesis includes economical evaluation of elaborated technology with other variants of production.
