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.

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.

The manufacturing of sheet metal part by blanking technology
Suchomel, Lukáš ; Špaček, Jindřich (referee) ; Peterková, Eva (advisor)
The master’s thesis elaborates an optimum proposal of the production technology of a cutting – a part made of steel plate 11 320.3. The theoretical part represents the problematic issue of cutting technology and on the basis of this part was designed a production of components in processual tool. The processual tool is composed of normalized components and is resolved by using a easel, which is attached into the eccentric press LEXN 100 C (producer Toma Industries) with the nominal drawing force of 1000 kN. The press was chosen on the basis of technological calculations. The work contains necessary calculations, economical evaluation and design documentation of the cutting tool for the components production. The last part contains the technical and economic evaluation of the recently designed technology.

Technology of production form - parts by forming
Bezděk, Jiří ; Císařová, Michaela (referee) ; Dvořák, Milan (advisor)
Graduation theses project elaborated within the scope of full-time study with specialization 23037002 submits the proposal of manufacture technologies for irrregularly formed component with flange by surface forming. Material is made from rust-resistant metal plate 17240 with 1mm thickness. Expected annual serie is 50.000pcs. Based on literary pilot project for deep hauling dilemma and its calculations was proposed hauling in instrument with blankholder. The hauling operation is done using hydraulic presser ZH 50 with rated power of 500kN. The drawing instruments are made from tool steel 19573 and heat treated according design doccumentation. The proposal of drawing versions was verified by simulation program Pam-Stamp.

The manufacture of hold-down arm by technology of fine blanking process
Mikyska, Josef ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
MIKYSKA Josef: The manufacture of hold-down arm by technology of fine blanking process. The diploma thesis deals with innovative technology of „hold-down arm“ by fine blanking technology. The component is made of steel plate no. 12 041.20, 3mm thick. The theoretical part presents possible solutions. In the project there are compared versions of fine blanking technology. Regarding the required size accuracy, surface quality and assumed series production of 600 000 pieces per year the fine blanking technology using V-ring was proposed as the innovative technology. On the basis of technological calculations the triple action hydraulic press GKP-F 100 (produced by Feintool) and a blanking tool were determined. The blanking tool solution is accomplished including calculations and futher documentation. Then, the project implies technical and economical evaluation of the present technology ( conventional blanking with consequentional cutting) and of the newly designed technology. According to the analysis using the newly designed production technology economic and time savings are achieved.

Manufacturing of motor lid using rubber
Brožek, Michal ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
The work, developed in an undergraduate study, proposes technology of the motor lid. The case shall be produced in a series of 300 pieces per year of 1mm sheet steel 17 240. After an evaluation of possible modes of production, the technology of fragile drawing tool, polytan, was chosen. Literary study is focused on the analysis of this technology. The circular shaped semi-product about the diameter of 222.3 mm, will be produced by a water jet cutting of thin plates with dimensions 1x1250x2500 mm. The capacity utilization of the panel is 68,3 %. For the forming component part is a hydraulic press Cth 250 at a nominal power of 2,5 MN, which is available and made by the company ŽĎAS a.s., used. On the basis of design calculations is a drawing tool for method Guerin designed. After the economic evaluation, the product price was set at 115 CZK.

Technology project for production of part "No.2432-cover"
Bednář, Martin ; Šlais, Miroslav (referee) ; Rumíšek, Pavel (advisor)
The project developed in the framework of Bachelor's study presents a proposal of producing technology of cover "2432", part of the sheet. Based on literature research, the studies and on own experience has been produced this work. The issue of materials, cutting, piping, drawing, design of the tool, evaluation of economic and technological design production has been studied. On the basis of the combined instrument has been designed, constructed according to standards, and the use of existing machinery. To resolve it was accounted economic assessment, which enabled decision-making between the semi-finished products for production. It was found that current production is not economically advantageous, compared to the options proposed. It has been ensured and the complex layout of machines in the area of existing production.
