Production of uncapping tray
Čudová, Monika ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
The project elaborated design of technology production of the extract - tray made of stainless steel 17 240. Based on literary study of deep drawing together with calculations, was designed drawing in instrument with holder. The drawing instrument make use of standardised components and it is solving forms to make up stand fitting to hydraulic press CYS 320, with nominal tensile force 3200 kN. Drawing punch and drawing die are produced from high alloyed steel 19 573 heat-worked according to drawing documentation.

The Tool for a Radial Expanding of Tubes by Liquid
Horák, Michal ; Lidmila, Zdeněk (referee) ; Peterková, Eva (advisor)
The submitted diploma thesis is focused on problematic of a radial expanding of tubes. In the first part of thesis, there is a summary of possible theoretical formulas for determining the stress-strain material parameters for biaxial bulging test of tube by liquid. Also there are showed several options for testing tools used in research abroad. The work also contains technological and control calculations for the selected test sample from the tube of steel 17 240 (1.4301). At the end of thesis, there are key points for tool design and there is also presented the proposed the test tool for a radial expanding of test sample of tube to the free space and with firmly fixed the ends of tube in the tool.

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.

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.

Production of wash basin drain grid
Běhounek, Martin ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
This thesis deals with a draft on manufacturing a sink grill. It is a rotary component that is made of corrosion-resistant steel 17 240. Considering the material, the shape of the component and the size of the production lot of 100 000 pieces a year, the suggestion for manufacturing this component is a technique of a deep drawing with no wall thinning. It has been decided that the trimming will be done with a progressive blanking die and the deep drawing will be done with the use of pressing machine LKDA 315. One part of this thesis is a draft of a design of a tool for deep drawing enclosed in a drawing documentation. In the economic segment, there is a total of expenses for one product which is 9 CZK. Production becomes profitable after manufacturing 67 308 components.

Production of filter cup
Míka, Tomáš ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
This work is concerned with the design of producing a filter cup made of material 17 240 (1.4301), 0,5 mm thick and the series 100 000 pcs/year, used in the lever of the espresso machine. The method of conventional deep drawing without wall thinning was chosen as the most suitable technology for the production of body cup. Utilizing calculations, an initial semi-product of circular shape with a diameter of 92 mm was determined. By means of technological and constructional calculations a single operation tool was designed, with the upper blank holder and knockout, which is intended for use with a double-acting press. Its functional parts are made of material 19 436. According to the calculated total force a double acting hydraulic press CTH 250 was chosen.

Manufacturing of cylinder holder by fineblanking technology
Piterka, Miloslav ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The thesis is focused on production of a cylinder holder, which has been made from stainless steel 17 240. The product is 6 mm thick and there are 200 000 pieces produced per a year. After analysis of manufacturing technology there has been selected fine-blanking technology with v-ring for production of these components. For this reason there has been developed a study. Then there have been evaluated the technological and control parameters of the components. There has been selected the single row arrangement on the sheet of tin and chosen a stock of blank metal sheet for manufacturing with strict measurements (8 x 1 000 x 2 000) mm. There has been made the suggestion of design of a cutting tool. Hydraulic press Feintool HFA 8800plus has been selected for the final production. Eventually there has been evaluated the economics of production of fine-blanking with v-ring due to break even point.

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.
