Production of a rotating vessel
Novák, Václav ; Žák, Ladislav (referee) ; Císařová, Michaela (advisor)
The thesis is concerned with the concept of an rotating vessel, that is a part of cotton candy machine. A drawing is cylindrical shape with circular a hole in the bottom, which is made of austenitic chrome-nickel steel 1.4301 with the thickness 1,5 mm. Due to the production volume 50 000 units per year, the pulling technology without wall thinning was choosen. The process of drawing will be performer in one operation. Due to calculated force, the ZHS 400 hydraulic press with a nominal force of 4 000 kN was chosen.

Progressive forming die
Bednařík, Josef ; Řiháček, Jan (referee) ; Lidmila, Zdeněk (advisor)
This thesis is focused on the technologi of surface forming. It deals with the problematics of metal cutting, bending and drawing. It describes basic construction principles of utilities and requirements they have to meet in order to function properly. Furthermore, the thesis deals with a basic description of the construction and function of progressive forming tools. In the final part of the thesis, there is a debate about differences in manufacturing a semi-finished product depending whether it is a roll of metal which is handed in automatically, or a sheet of metal which is handed in manually.

The line borders
Kazdová, Kristýna ; Sikora, Piotr (referee) ; Mikyta, Svätopluk (advisor)
The difference in perception of reality is caused by the language that creates the terminology for naming formal entities; the definitions of these concepts are abstract. This creates both a collective inconsistency and an incongruity between content and form. In consequence, the question of the objectivity of attributing an abstract image to specific material should be asked. Elementary elements of the drawing expression as a line/picture are primarily perceived in formal boundaries. The goal of my work is to move beyond these boundaries.

Production covering grids of welding machine
Rous, Miroslav ; Štroner, Marek (referee) ; Císařová, Michaela (advisor)
This thesis has been written in the time of my bachelor studies and it describes a production design of a rear cover of a welding set. It focuses on manufacturing of ventilating holes in this component. The cover is made of steel of standard quality 11 320, 1 mm thick. The flattened out shape of the component will be stamped on a Finn Power SG6 machine and subsequently it will be bent on a press brake Safan DNCS 225-4300. The practical part of this thesis contains a design of an instrument making the ventilating holes and an economic assessment.

Manufacturing of parts of microforming technologies
Janoušek, Jiří ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This work deals with point incremental forming technology, which is now booming thanks to the possibility to program the exact path of a simple tool and to implement it on modern CNC machines. It solves the forces in the process, the roughness of the final surface of the products or their accuracy. This technology is divided into one-point and two-point forming and uses better material formability because of little local touch. Thanks to this, it is used in many fields such as medicine or the automotive industry. It is used to produce prototypes and specific components, which would be expensive.

Production of the electric motor cover
Havlíček, Lukáš ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The present thesis solves a design of electric motor cover; specifically it deals with manufacture of cover body. A drawing is of simple flange-free cylindrical shape made of deep-drawn 11 305 steel sheet. With respect to the given shape of the component, material and annual series of 25,000 pieces, the most suitable technology selected was the method of deep drawing without thinning the wall by means of conventional tools. The process of deep drawing will be performed using a single-acting deep drawing tool supplemented with technical documentation. This tool is designated for the hydraulic press ZH 40 with a total drawing force of 400 kN. In the technical-economic part, the price of one product (respecting the indirect costs) was calculated for 42 CZK.

Manufacturing of cover
Březina, Stanislav ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The graduation theses worked up within the frame of the master study programme M21-P, field of study M-STM, sets up a proposal of the technology of the casing manufacture. The casing will be made of steel plate 11 305.21. In terms of a linear study of the questions of deep drawing and the calculation, drawing in the instrument with blankholder was suggested. The upper ejector is instrumental to the extension of the components. The intermediate product will be a roundel created by scission of the sneet panel of 1 mm size. The average of the intermediate product is 124,7 mm, while series 100 000 pieces a year. In terms of the calculations for the operation of drawing, the hydraulic press ZH 30 with specified forming power was selected.

Forming modern technology in engineering
Kalous, Ondřej ; Schwarzer, Emil (referee) ; Dvořák, Milan (advisor)
The project elaborated within the bachelor‘s degree field of B-STI Mechanical Engineering submitting literary pursuit of modern forming technologies in engineering. This thesis deal especially with fineblanking technologies, drawing of elastic tool and high-velocity forming. Description of their principles, advantages and disadvantages. In the last part of thesis was contrast production of driving chain gear with conventional and modern technology.

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.
