Design of pressing tools
Hostinský, Michal ; Henzl, David (referee) ; Žák, Ladislav (advisor)
Metal cutting, a technology of plane forming, belongs to the group of progressive metal treatment processes. Compared with new technologies of metal machining, metal cutting still has its unique place in engineering production. This project aims at cutting plates of conveyor chains, which are subsequently used in the production of connecting offset links. When rating the technological process of component production, various surveys and economic comparison, metal cutting has been evaluated as the most suitable technology. With this objective an adjustable cutting tool has been designed, intended for use in the production of the ŘETĚZY VAMBERK company, which is one of the leading manufacturers of roller and conveyor chains in Europe.

Influences of pickling on coating bonding power
Staněk, Vít ; Žák, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
Works created within the engineering studies in collaboration with IDEAL-Trade service discusses the influence of pickling acids on steel material and on the same material with powder coated . Based on the literature study and consultations with employees of the company were designed each experiment, investigators removal and acid corrosion attack , another verify adhesiveness powder coatings for various periods of exposure pickled material. Experiments and tests were carried out in companies ECOS , ITS and faculty FSI.

Production of a Printing Machine Waste Track
Dolák, Martin ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
Řešenou součástí je část kanálu pro odpadové odstřižky tiskařského stroje. Relativně jednoduchá součást vhodná k výrobě tvářením za studena. Diplomová práce navrhuje zhotovení komponenty lisováním. Po shrnutí základních teorií dále navrhuje varianty výroby. Pro vybranou sestavuje technologický postup a navrhuje kroky tváření. Návazně odvozuje návrh konstrukce postupového nástroje. V neposlední řadě se věnuje ekonomickému vyhodnocení výroby, ročnímu výrobnímu množství a vypočítává bod zvratu pro dané řešení.

Production of air filter cover
Procházka, Vojtěch ; Žák, Ladislav (referee) ; Podaný, Kamil (advisor)
The thesis is concerned with the concept of an air filter cover production .The component has a cylindrical shape with a circular protrusion and a hole in the bottom. It is made of a steel sheet 11 320 with the thickness 1 mm. Considering the production volume of 20,000 units per year, it was chosen as the most suitable pulling technology with a conventional tool without wall thinning. The component needs to be pulled in two operations, each time a retainer has to be used. The tool for each operation is separate. Technical drawing documentation is processed for the second tool. Due to the calculated force, the ŽĎAS CTH 250 hydraulic press with a nominal force of 2,500 kN was chosen. The economic evaluation shows that the production material cost for one piece is about 42 CZK. The cost of the second stroke tool is 260,000 CZK.

Design of lighting cover production
Bahula, Jan ; Žák, Ladislav (referee) ; Podaný, Kamil (advisor)
The project elaborated design of technology production of the lighting cover – rotating extract from the deep drawing sheet iron DC01 0,5 mm thick. Pursuant to analyses of production and calculation was designed drawing in conventional instrument with holder in one operation and the cup is being wiped by the die. The drawing instrument make use of standardised and construction components and it is solving forms of customary stool clamped by clamps on the hydraulic press CUPS 40 DEU, with nominal tensile force 400 kN. Drawing punch and drawing die are produced from alloyed instrumental steel 19 436.9.

Defects and their causes in dyeing of anodized surfaces
Šulc, František ; Žák, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
This thesis deals with the anodic oxidation of aluminum and its alloys. The work consists of two parts. The first one is focused on more detail description of anodic oxidation process itself and theoretical description of the technological process anodic oxidation. The second part is more practically oriented. It compares two different lines for anodizing, and examines factors that affect the final appearance of the surface layer during anodizing welded joints.

Production technology of a plastic headlight panel in a car
Vrána, Petr ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
Diploma thesis which is developed for the master’s degree program (M2I – K Mechanical engineering) presents a proposal solution for production technology plastic car headlins parts from polymer material PBT GF30. Literature review summarizes the findings of thermoplastic injection technology and the structural design possibility of injection molds. The paper examined two variants of the running system, which are suitable for production of injection molding components. Finaly, after technical - economic assessment, we came to the conclusion that the better option is to use the hot runner system. In the practical part is the specified product modeled by the help of 3D software and the injection mold was designed. The design was implemented by CATIA V5 R20. For the design and manufacture of injection mold were used normality from MEUSBURGER. For the chosen alternative technology of production were made calculations and was selected injection molding machine Electron 75 – 300 from FERROMATIC.

Technology of production components from plastic material
Špičák, Pavel ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The project developed in terms of engineering study of field N2307- 00 Engineering Technology submits a design of components from plastic production technology- cover on the table. The introductory part of this study describes characteristics, division and possible plastics processing. The work consists of production technology proposal (injection into metal mold) and its construction solution. The another part proposes suitable injection material and verification of injection machine. The final part of work consists of financial evaluation of injection process, appropriate blue prints and appendices.
