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.

Manufacturing of the Ignition Case
Jelínek, Dan ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
The thesis deals with the design of the production of Ignition case. Component is a hollow cover of one channel ignition device, produced by the PBS Velká Bíteš company. It has a constant wall thickness of 0,5 mm and production rate is 15 000 pieces per year. Technology of deep drawing with solid forming tool was picked out of several considered production variants. DC05 deep drawing steel is the material of choice. Based on technological calculations, number of drawing operations needed and forming force was established. Based on those parameters, hydraulic press ZH 10 produced by the Presshydraulika s.r.o. company was chosen for the task.

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.

Production of check valve's part
Růžička, Pavel ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
The bachelor's thesis deals with the production innovation of the return valve disc component used in pumping technology. It is a component made of sheet metal with 3 mm thickness, the quality of material is according to ČSN 11 320. Existing production using cutting technology in a process tool will be replaced by a modern, more accurate and especially more economical method by precise cutting with a pressure edge. Based on the literature study of precision cutting, assessment of production technology and processing of design solutions, the cutting tool was designed to be able to significantly speed up and reduce the cost of production of the component. It will be placed in a three-acting press from Feintool, namely XTF Speed with a nominal force of 1500 kN. In the final technical and economic evaluation, it was proved that the newly designed technology is able to bring a component of the same nature to the market, but at a significantly lower price.

The modern processes and technology of sheet metal parts forming
Řáda, Aleš ; Císařová, Michaela (referee) ; Dvořák, Milan (advisor)
This bachelor thesis contains the summary of methods for unconventional sheet metal forming and tube forming, especially in flexible tools. There are some technologies such as rubber pad forming, hydroforming, high-speed forming and hot forming presented. In next part of the work there are three hydroforming methods for tube components described: low-pressure, high-pressure and pressure-sequence hydroforming. Finally there is comparison of these technologies according to several aspects by available web sources.

Manufacturing of wall clamp
Maleček, Michal ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
A wall clamp is used for attachment of terrace board to supporting structure. The discussed part is manufactured from sheet metal 11 375.20 which is 2 mm thick. The production series will be 150,000 pieces per year. A combination of shearing and bending in the combined tool was selected from a variant solution as the most suitable technology of manufacturing. Based on technological and structural calculations, a tool was designed with lower pressure pad at the bend point. For this tool was also made fundamental drawings. In view of the total moulding force and work, LEN 40 C press with the nominal force 250 kN (manufactured by TOMA INDUSTRIES s.r.o.) was selected. Necessary manufacturing costs of one part were determined from an economic evaluation. According to a break-even point, the manufacturing becomes profitable for a series of more than 89 196 pieces.

The manufacturing of coating metal sheet part
Sykáček, Jiří ; Hušek, Martin (referee) ; Císařová, Michaela (advisor)
SYKÁČEK Jiří: Production of a sheet metal part with a surface finish This project, elaborated as a part of my B2307 bachelor studies, has been compiled on the basis of a customer requirement to produce a battery cover exposed to an increased corrosion risk. It deals with the production technology of the part using various sheet metal materials of different surface finish. The most suitable solution has been found in using a cutting and a bending press. The chosen production method has been evaluated with regard to technological difficulties connected to processing thus modified sheet metal as well as with regard to economical cost of the production. Forming processes have been executed using a TRUMPF TC200R cutting press, having a nominal shearing force of 165 kN, and URSVIKEN Optiflex bending press, having a nominal pressing force of 1300 kN. Forming tools are optimally chosen according to the parameters of individual types of sheet metal. At the end the project evaluated the most convenient material to produce this part.

Manufacturing technology of the distance washer
Dvořák, Jiří ; Podaný, Kamil (referee) ; Císařová, Michaela (advisor)
This master’s thesis has been elaborated as a part of master’s studies of engineering technology M2I-K, major in M-STM – Engineering technology and industrial management and deals with the problem of a transition to a self-production of previously purchased distance washers. Distance washers were purchased in six different types of similar shape, each type in four different thicknesses. One of these types was chosen as a representative for this master’s thesis. We shall explore the possibilities of self-production with the emphasis on economical validation of the transition. The distance washer is a flat part, the intermediate being sheet metal. Technologies considered for manufacturing the washers correspond to the technical facilities and equipment available at the production hall of the company this project is planned for. The company possesses technology for CO2 laser cutting, cutting by CNC punching machine and cutting in the punching tool. To provide a complex overview we shall also enquire into cooperated technologies such as water jet and plasma cutting, oxy-acetyleny cutting and CNC working. All options are evaluated with regard to the production expenses and lead to a most economically plausible method of manufacturing or, if need be, give reasons for going back to purchasing the part from the current supplier.
