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.

Production of cooling cabinet
Halabrín, Marek ; Peterková, Eva (referee) ; Císařová, Michaela (advisor)
The thesis deals with presenting an assembly proposal of a cooling cabinet. The cooling cabinet is made from an austenitic steel plate of the ČSN 17 240 grade with a thickness of 1.5 millimetres. The assembly proposal is composed according to the design documentation. The number of the assembled pieces is 200. The manufacturing shall be made with the use of bending and punching. These manufacturing techniques form a part of this thesis. Finn power C5 with a nominal force of 300 kN and Trubend 5170 with a nominal force of 1700kN are the machines chosen for the manufacturing process. These are standardized machines made from a quenched steel and a steel of the 42CrMo4 type. A technological-economic evaluation comparing expenses of the manufacturing also forms a part of the thesis as well.

Numerical simulation of a tube flaring under dynamic conditions
Hlavačka, Daniel ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The thesis builds on the project FSI-S-14-2394, in which the biaxial state of tension of longitudinally welded tubes made from material 17 240 was investigated. The experiment was carried out under dynamic conditions on an impact tester, which was designed with structural simplicity and ease of observation of the experiment in mind. Deformation was recorded by high-speed cameras and a dynamometer. Results of the experiment were processed by measuring devices and subsequently used in a simulation created using a software utilizing the finite element method. Simulations were created for samples DA8 and DB9. These samples were selected because they did not crack and were fully stamped. Results of the simulation correspond to the values measured by high-speed cameras and a dynamometer with a small variance. Based on comparison of the results, it can be states that the simulation is technically acceptable.

Manufacturing of wall clamp
Kourek, Lukáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The project which was work out in bachelor thesis is setting up a production for an wall clamp. Component is made from corrosion resistant steel plate 17 240 thickness 0,7 mm in form of roll. Produce´s series is determined in 500 000 pieces/ year. Based on the literature study was chosen optimal production technology of cutting and bending. Technological and structural computation were accomplished for these technologies, owing to them was projected combined follow-on tool. Eccentric press LEXN 100 C, which reaches expressed force, was chosen by needful size of total forming force 1000 kN.

The manufacturing of pulley cheek by technology of fineblanking process
Robotka, Tomáš ; Dvořák, Milan (referee) ; Peterková, Eva (advisor)
The Master´s thesis is elaborated within the framework of graduate´s study by institute of The Engineering technology and composed the technology of fineblanking process. The required component is made by stainless steel 17 240. The technological and constructional proportions were designed and calculated for required technology. The tool cuts out for one stroke one component, and is designed for mechanical three-active press MFA 1600 made by Feintool. The material’s strip of the scroll is situated in single sided rewinders QOPJ 160/650, and managed through leveling machines QRVP 160 into tools. The total force of press is 1600 kN. The main functional parts tools are made by steel 19 436, 19 437.

Laser cutting with air pressure assistance
Kramoliš, Lukáš ; Hála, Michal (referee) ; Mrňa, Libor (advisor)
This project, elaborated within the engineering studies (code of field of study: N2301), deal with air supported laser cutting and its practical usage in industry. The project is divided into theoretical and experimental sections, consisting of detailed description of several successive steps of the experiment. The theoretical section describes the principle and function of laser, individual types of lasers and their classification, laser beam properties, laser cutting, etc. The practical part is focused on finding of a set of optimal cutting parameters, assessment of results of air supported laser cutting in terms of quality and accuracy of cutting surface. This part is followed by comparison of cutting surfaces with a conventional technology of laser cutting that uses oxygen and nitrogen. Final part of the project evaluates applicability of this unconventional technology from the economic point of view.

Pressing punches on austenitic stainless sheet
Rudolf, Bronislav ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
Thesis resolvs proposal punches in the sheet metal for heat transfer solar panels. Shapes of punches are selected – piramidal shape and lengwise shape. It is reviewed their possible production and the selected method of Guérin is described. Sheet metal from austenitic stainless 17 240 is selected for the manufacturing. Forming tool is designed with interchangeable punches and elastic medium for various modifications and comparing shapes of punches. It is used hydraulic press CZR 600 for a experimental production.

Production of shower tray
Černý, Vít ; Žák, Ladislav (referee) ; Císařová, Michaela (advisor)
The thesis deals with design of technology production of the shower tray made of austenitic steel 17 240. Based on the research of deep drawing and calculations, it was proposed to draw in the tool with upper blankholder and the lower ejector. The drawing tools uses standard components that ensure its functionality and clamping in the CYA 500 hydraulic press with nominal tensile force of 5000 kN. Drawing punch and die are made of 19 437.3 grade steel, heat treated according to the attached drawing documentation.
