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.

Technology for PC-box side production
Pašalov, Tomáš ; Horák, Jaroslav (referee) ; Rumíšek, Pavel (advisor)
The project developed as a part of continuing master’s program in the field of M-STG Mechanical engineering technologies introduces a technological proposal of producing a side panel of computer case. Based on the research of published studies on the topic of surface forming and methods of production of shape openings in sheet-metal, we chose the variant of production of parts using punch press and press brake and selected appropriate material – steel with protective zinc and aluminum coating. Based on the research of published studies on the topic of computer cases we processed analyses of shape designs and chose optimal variant, for which we prepared calculations of production costs in comparison with other proposals.

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.

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.

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.

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.

Design for production of lower part of charging station
Skalník, Petr ; Zavadil, Radek (referee) ; Podaný, Kamil (advisor)
This master’s thesis deals with a proposal of production technology of bottom part of charging station which is manufactured by DEL a.s. The component will be made of austenitic steel 17 349 which is 2 mm thick and its production series is 100 pieces a year. Punching and bending by MAG and TIG methods were chosen as the most suitable methods from the considered manufactoring technologies. Stud bolts will be welded by capacitor discharge. Based on the analysis of the technological calculations and the available machines in the manufacturing company was chosen that production is going to run through a punching press Pullmax 720, hydraulic CNC bending press OptiFlex 130 t 3,1 and welding sources TransPuls Synergic 3200, TransTig 1750 Puls and Nomark 65+. Technical and economical evaluation established cost calculation of semi-finished product material, welding wire, gaseous shield and stud bolts. The price of one piece is 3 117,70 Czech crowns.

The manufacturing of a flange by fineblanking technology
Povalač, Tomáš ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
Aim of the project is to design new flange manufacturing technology. The flange is manufactured from stainless sheet 17 040 with 5 mm thickness and annual production batch of 800 000 pieces. Fineblanking process has been proposed as a new production technology. Technological and construction dimensions have been designed for the proposed technology. The fineblanking process is done by automated machine which consist of unwinding and straightening device, mechanical punch press and winding device. The manufactured part is punch pressed by tool which is located in the punch press in one lift. An economic evaluation compares current manufacturing technology with the proposed technology which is more economically convenient.
