The suggestion of shaped hollow cup technology
Fabík, Pavel ; Šlais, Miroslav (referee) ; Císařová, Michaela (advisor)
The project developed in the master's degree in M2-P, proposes a technology of hollow metal components DX53D+Z275N+NC with holes sheet metal forming. For batch production 225 000 units per year, on the basis of literary study problems of production of components there is designed a new way of producing components for progressive tools and it is compared with current production of simple tools. A progressive tool has 12 steps and combines them in cutting, drawing and extrusion. The tool is mounted in the hydraulic press KAISER KSTU2500 with a maximum force of 2500 kN. Simulations were performed for the campaign in the PAM-STAMP 2G 2011.

Production of carpentry joints
Kliš, Vojtěch ; Žák, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
The thesis deals with the design of the technology for the production of the galvanized sheet. It is a carpentry joint that serves for joining wooden structures. The work is focused on metal forming, namely cutting technology. Based on the production series of 30,000 pieces/year, the shape and dimensions of the part, the method of shearing was chosen for production. Furthermore, the necessary technological calculations were performed. The tool consists of standardized components that have been selected based on the standards. For production was chosen eccentric press S 160 E from the company Šmeral Brno a.s. The price of one component is CZK 9.

Production of the "Pant" component
Šidlák, Jaromír ; Lidmila, Zdeněk (referee) ; Žák, Ladislav (advisor)
The thesis presents a proposal for manufacturing a basic hinge body. Together with the base, it forms an assembly that can be used, for example, in letter boxes or switchboards. The component is made of 3 mm DC01-A-m steel and has an annual production run of 10,000 pieces. The part has a galvanic zinc surface treatment. After considering possible production technologies, production in a progressive shear tool was chosen. The production process was designed to produce the hinge from steel sheets cut into strips. Based on the calculations, a suitable cutting plan was then chosen and the necessary pressing force and labour was calculated. The LEN 63 C press from the manufacturer ŠMERAL Trnava was chosen for the production. The thesis also includes designing the progressive tool, which was based on the necessary calculations. The tool itself was designed mainly from standardized parts. An economic evaluation of the design was also made. It determined the required quantity of material per production batch and the selling price of the basic hinge body, which is CZK 11.9 per piece.

On the coating of shearing cemented carbide tools
Nováková, Radana ; Šurda, Adam (referee) ; Píška, Miroslav (advisor)
Tato diplomová práce se zabývá problematikou PVD povlakování střižných nástrojů ze slinutých karbidů, se zaměřením na zvýšení životnosti postupových nástrojů. Především poukazuje na využití povlakovaných nástrojů v praxi a procesních kroků před a po procesu povlakování. V teoretické části jsou popsány obě základní metody povlakování, tj. fyzikální metoda PVD a metoda CVD, založena na chemickém procesu. Dále jsou představeny jednotlivé způsoby vlastních procesů povlakování se stručným popisem výhod i nevýhod jejich využití. Praktická část je zaměřena na testování, jehož podstatou byl nejen vhodný výběr samotného povlaku pro daný materiál, ale i úpravy před a po povlakování, které jsou často opomínány. Ty jsou však nezbytnou součástí a mají výrazný vliv nejen na výsledný povlak, ale i na kvalitu pracovního procesu. Vyhodnocením experimentu je souhra určení nejproduktivnějšího povlaku v závislosti na dané úpravě.

Production of rack moulding
Repatý, Michal ; Podaný, Kamil (referee) ; Žák, Ladislav (advisor)
The paper evaluates technological, economic and construction aspects of the component production and the design of the tool serving for large-scale production of the S355MC steel rack component. Use of a progressive tool combining cutting and bending operations in four steps has been decided as the most appropriate according to literature study. Based on the need of production of two plane-symmetrical pieces at a time, the tool will produce both pieces simultaneously, which is economically advantageous. The tool is designed for use on the Arisa 630t mechanical press. Material will be winded off the roll, flattened and pushed into the tool by a precision feeder. The total cost of production of the component was set at 18.80 CZK.

Production of component the Cage ECR 10 12
Jílek, Josef ; Heinl, Tomáš (referee) ; Žák, Ladislav (advisor)
The thesis focuses on the production concept of component Cage ECR 10 12, which is used as assembly element together with a nut during the bus production. Sheet metal part is made from 11 321 steel 1,5 mm thick in production 10 000 parts per year. Technology of production in progressive tool was selected based on literature study. Progressive tool combines technology of shearing and bending. Tool was designed after the technological calculations. Forming machine was selected after the stamping force calculation. Eccentric press LEN 63 C with 630 kN forming force was selected for production.

Production of anemostat
Bíba, David ; Žák, Ladislav (referee) ; Císařová, Michaela (advisor)
The thesis handle design of part of anemostat in size of series 15000 pcs/year. Due to conus shape and dimensions of part was chosen out of quantity of manufacturing processes a technology of deep drawing without a thinnig of 1mm thick DC04 steel. The resulting solution is progressive tool which concatenate four operations of deep drawing process. The drawing tool make use of standardised components. The design contain progressive tool including drawing documentation. Hydraulic press CTH 400 with nominal force 4000 kN is used for mentioned procedure.

Manufacturing technology design of the automotive door hinge
Dvořáková, Jana ; Císařová, Michaela (referee) ; Dvořák, Milan (advisor)
The bachelor thesis presents a production proposal of an automotive door hinge from the sheet metal ČSN 11 321 and an economic evaluation of the chosen variant. The hinge is produced in a combined tool by shearing and bending operations. The tool is clamped to a ZH 2500-2000 NG mechanical press with a nominal force of 2500 kN. Because of the press parameters, alternative solutions are proposed that could lead to an increased capacity utilization. Part of the thesis is a literary research, the output of this research is an overview of cutting technologies with evaluation of their suitability for production of the given part, theory of bending and stamping technologies, a brief outline of the possibility of component production by a method of additive manufacturing and theoretical calculations. Technical variants of series production tools are compared as part of the technical and economic evaluation. Drawing documentation of a component and of a tool are listed in the attachment.

Bulk forming technology of grooved charge
Sklenář, Luděk ; Samek, Radko (referee) ; Forejt, Milan (advisor)
SKLENÁŘ Luděk: Bulk forming technology of grooved charge. The project prepared as part of the Master-degree studies in the Manufacturing Technology and Management in Industry, concerns the technology design for manufacturing a grooved charge by cold bulk forming. Grade 12 040.3 (CSN) steel was used as the initial material. For the batch of 50,000 pieces per year are proposed three alternatives. The chosen option No. 1 is made of technology and tensile strength calculations for metal forming operations: upsetting, backwards extrusion, forward extrusion and calibrating. The grooved charge production is designed for two forming processes that will be realised at the Colombo press Agostino, which is part of the machinery park company Metaldyne Oslavany. The extruding dies for the manufacture are made of tool steel 19 655 and tool steel 19 830 is designed for extruding punches.
