Productive single parts from shet metal by the help of technology Hydro- Mac
Štancl, Jiří ; Dvořák, Milan (referee) ; Žák, Ladislav (advisor)
The project in this bachelor thesis solves a proposal of design technology production of extract from deep sheet iron 17240, thickness of 2 mm. Pursuant to of the literary pursuit a problem of the deep drawing, calculation and production of 40 000 pieces a year, was designed hydromecanical deep drawing. Drawing tool is fixed in hydromechanical press EMU 4000 by AP & T company. This press reaches nominal force of 4000 kN. Drawing punch is produced from instrumental steel 19 436, heat-worked according to drawing documentation.

Production of components "Key pouch"
Kašpar, Jan ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The main aim of this thesis is the production of injection moulds for a given component key pouch. The first part of the work describes the basic division of plastics, plastic injection technology and principles of mould construction. The second part deals with actual mould construction processed in Solidworks. The drawing documentation is the output. In conclusi-on, an economic evaluation is completed that will provide approximate cost of production moulds.

Production single parts "Holder for rail mounting on curtains"
Pytlík, Radek ; Štroner, Marek (referee) ; Žák, Ladislav (advisor)
The project developed within the bachelor degree is proposing a technology of manufacturing a holder for rail hinges made of galvanized sheet steel 11 305, 1 mm thick. The production run is set at 20,000 units a year. According to literary studies concerning cutting and bending, as well as on the basis of calculations, cutting in an operating cutting tool and bending in bending tools were proposed. LEN 40 C – an eccentric press and CDC 2 – 7 hydraulic press are used for the production. The cutting punch, cutting die, bending punches, bending dies are made from tool steel 19 436.3.

Cutting components with higher accuracy to size
Steiner, Jaromír ; Varjan, Matúš (referee) ; Žák, Ladislav (advisor)
The main topic of this thesis is the fineblanking technology with a vee-ring which was chosen as the most suitable solution. The aim is a design and an assessment of technologicity of the selected component, a draft of the structural design of the tool and an economic evalua-tion of the project. The chain wheel has been designed from structural steel 11500; parameters have been evaluated as appropriate. The instrument has been designed as two-station progressive tool for single-row layout of the fineblanked parts with a moving punch; the vee-ring is positioned both to the blanking plate and to the vee-ring plate. The press was chosen on the basis of the calculated shearing force by Feintool Company. At the selected batch 500,000 units, 5.1 CZK per fineblanket part has been calculated.

Production of the component "Lid"
Vyhnanovský, Jaroslav ; Rumíšek, Pavel (referee) ; Žák, Ladislav (advisor)
This project developed within the Bachelor study of Engineering Technology proposes a technology component “Lid” made of1 mm thick sheet metal ofmaterial11 375(1.0038). The component will be made on a combined roll forming machine. A mount with two pillars will be used for the production, which will be located in an eccentric press LEN 40C by TOMA Industries Ltd. based in Trnava, Slovakia. The nominal press force is 400kN. Trimming punches, broaches, blanking dies and bending punches are made of tool steel, grade194....

Technological structures formed parts
Kafuněk, Jan ; Žák, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
The bachelor‘s thesis is composed from research and is described in practical part. Searches contains basic information about the process of cutting, bending and tractioning, which is followed by a description of design principles in the design of sheet metal parts. The practical part is focused on verifying the importance of complying with technological design of products. Products can be divided into the sample products without practical use and products that can already have their use in practise.

Production single parts "Bracket" from sheet metal
Buchta, Petr ; Lidmila, Zdeněk (referee) ; Žák, Ladislav (advisor)
The project which was developed in the framework of a bachelor's degree submits a proposal of production of steel material 11373, shearing and subsequent bending. The main topic of this thesis was to create tools that would allow a simple and inexpensive production of components. Tools have been designed and manufactured on the basis of literary studies issues, associated with shearing and bending. The function parts of the instruments are made of tools steel class 19.

Production of the top of the pressure container
Sobotka, Jiří ; Císařová, Michaela (referee) ; Žák, Ladislav (advisor)
The project developed within the bachelor's degree, proposing a technological parameters of injection molding and tool design for plastic product– segment was suggested from the material PA 6 NOVAMID B30P nature. On the basis of literary study of technological plastic mould injection issues and experiences there was suggested mould injection tool with tunnel inflow, classical extractor was suggested for pressing demoulding. The mould uses standardized components and it corresponds by dimensions with production device ARBURG 420 C 1300-350 (manufacturer ARBURG Gmbh + Co KG, company Loßburg) or ENGEL VICTORY 500/120 Tech (manufacturer Schwertberg, company Schwetberg), with closing force 120 kN or 130 kN. The mould is produced from alloyed tool steel 19 436.9 (POLDI 2002).

Production technology of the plastic top cover
Majerčíková, Erika ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
This thesis deals with the production technology of the plastic top cover by injection molding. Series production is set at 500 000 units, for which the required period of delivery is 9 months. A literary study is developed, focusing on the technology of injection molding in molds in the first part of the thesis. The second part is practical, which includes a design technology for the manufacturing of the plastic top cover, namely: the choice of material, determination of process parameters, the choice of the injection molding machine, and the injection mold design. The chosen material is a polyamide 6 with 30 % share of the glass. According to technological parameters of injection, the injection molding machine, Engel ES 200/65, was chosen. The injection mold is composed of standards parts of the company Meusburger and HASCO.

Manufacturing of connector
Kočka, Jiří ; Žák, Ladislav (referee) ; Podaný, Kamil (advisor)
The bachelor thesis deals with a concept of the production technology of the connector. It is made of CuSn6 bronze plate of width 0,25 mm, production batch of 1 200 000 pieces per year.There was performed a recherche based on the topic. Out of available technologies for the production were chosen cutting and forming in follow die. For the cutting of the bronze plate was chosen high-speed press machine Bruderer 18 with nominal pressing force of 180 kN made by E. BRUDERER Maschinenfabrik AG. The production costs per one piece were evaluated in the economic analysis including manufacturer profit and there was defined break-even point which occurs after production of 876 282 pieces.
