Forming technologies of non-ferrous materials
Zuhla, Michal ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
This work is focused on the surface forming, in particular, non-ferrous metals. There are described methods of cutting, drawing and bending. For each of these methods are listed and summarized the issues. There are also given individual production technologies cutting, drawing and bending, along with examples of products and their use. The work is complemented with an overview of the most important non-ferrous metals. For these metals are described their properties, suitability for molding and their alloys.

Productive single parts from shet metal by the help of technology Hydro- Mac
Štancl, Jiří ; Dvořák, Milan (referee) ; Žák, Ladislav (advisor)
The project in this bachelor thesis solves a proposal of design technology production of extract from deep sheet iron 17240, thickness of 2 mm. Pursuant to of the literary pursuit a problem of the deep drawing, calculation and production of 40 000 pieces a year, was designed hydromecanical deep drawing. Drawing tool is fixed in hydromechanical press EMU 4000 by AP & T company. This press reaches nominal force of 4000 kN. Drawing punch is produced from instrumental steel 19 436, heat-worked according to drawing documentation.

Optimal layout proposal of technological workplaces at a small mechanical engineering company
Mohorko, Martin ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
This master´s thesis is focused on technological designing in a small company ENGITEC Motosport s.r.o. In first theoretical part of the thesis is this subject described in detail and analyzed in terms of economic and technical aspect. Next part describes the current state of the company and the production hall as well with keep on its current layout. In the following chapters is chosen piston-shaped component, which is manufactured by the company and three different variants of the piston production. Then one of them is selected, to which all related capacities calculations are made. In the final part of the thesis is proposed the relevant final layout of the hall and there is also the technical-economic evaluation of the most relevant variant included. Key words

Design of Forming Tool and Machinery for Couting out of Pad
Kolář, Milan ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The Diploma Thesis presents a draft of designated automatic apparatus for cutting out and assembling pads for pressure control valve (DRV2). The theoretical chapter of the Thesis contains selected findings from theory and technology for material cutting. The next chapter contains design solutions for a designated apparatus for cutting and assembling pressure control valves. The pads are etched from 0,08 mm steel plates X2CrNi Mol7-12-2. The shape of the pads is etched on a 35mm-wide belt that is wound up onto a drum. The draft of this new technological facility has been elaborated in accordance with the most suitable technological variant. The cutting tool is made of steel 19 437 that is thermally processed at HRC 62-4. Estimated annual volume of production series is 2 mil. pcs. The cutting and assembly processes are executed with the aid of this designated automatic apparatus.
