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.

Production single parts from sheet metal on two-station tool
Vrána, Petr ; Špaček, Jindřich (referee) ; Žák, Ladislav (advisor)
Projects developed within the bachelor's degree in engineering technology (B3S-K Engineering) technology by design sheet metal parts 11 373.1 on a combined tool. Based on the literature studies about cutting, bending and stretching has been proposed several variants of the production of specified parts to be produced entirely in a single tool. The proposed tool is clamped in the eccentric press PE 100 D firm ERFURT with a nominal force of 1000 kN. The functional parts are made of tool steel, 19 436 heat-processed according to drawings. Punches are made as a split because of interchangeability and easy repairability.

Production single parts "Setting Base"
Dluhoš, Jan ; Henzl, David (referee) ; Žák, Ladislav (advisor)
The bachelor`s thesis, which was written on the grounds of the bachelor`s study programme B3S-P Mechanical Engineering, the field B-STG Technology in Engineering, deals with the production of moldings for transport of copy devices abroad. Molding is used for setting of the device in wooden box and it is placed on silentblocks to avoid damage of the copy device. The bachelor`s thesis contains a study of the particular issue, a proposal for the cutting machine and bending machine together with an economic evaluation.

Surface treatment of car body by frosted finish
Kubíček, Dominik ; Žák, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
The bachelor thesis focuses on the problem of surface treatment of car body. It is dedicated to the theory of this problem, to the treatment of metal surfaces, division of different types of treatment as well as to the necessity to protect the surface from corrosion. Next part is a summary of technologic progress and application of frosted finish on the car body. In the end, we point out some mistakes caused by the violation of principles of vehicle paintwork.

Surface treatment by wet paiting
Fical, Karel ; Žák, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
Protection of various coating materials is today very important, both in terms of aesthetic, functional and, especially corrosion. Corrosion annually causes significant damage to metal structures and degradation of material can cause a total damage of the parts or the whole structure. When appropriate choice of coating materials can suppress the corrosion and its manifestations delay up to several years. Today, the protection of organic material coats the most common way and takes 80 to 90% of all coatings. When selecting paints and their subsequent applications we care about the material properties of the edit, its functional use, the environment in which they will be located and the properties of paint itself. To achieve satisfactory properties, it is necessary to create a technological process for the specific case.

Production single parts "Case of coil winding"
Rudolf, Bronislav ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
Bachelor´s thesis is elaborated in terms of branch B-STG engineering technology. Smoothing - out suggestion manufacturing engaged plastic parts from material PA66- GF25 FR by the help of injection technology. Firstly, the basic materials for injection are described, then is described injection principle, injection mold and injection machine. The practical part deals with their own forms of construction. In the inclusion is simple economics upward revaluation expense and surplus.

Production single parts from thermoplastic "Magazine cover"
Říha, Pavel ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The Bachelor´s thesis is concerned about thermoplastic injection technology. In the theoretical part are described actual knowledge in branch of thermoplastic injection and there are summarized the recommendations for design of injection mould also. The practical part describes the prototype injection mould design for designated plastic part. One of chapters includes technology analysis of plastic part. The mould is projected in Pro/Engineer Wildfire 4.0 software including complete technical documentation . In the end of this thesis is performed economic analysis of production costs.

Repair of car body
Tolkner, Josef ; Žák, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
The work deals with the issue of repairing the car following a minor accident, or his body and especially her painting. Bachelor's thesis has been designed to help inexperienced drivers to fix their cars with minimal cost and to yourself. At first, I deal with the profitability of their own work-if not paid the car repair due to its condition and price compared with estimated costs of repair and time consuming work performed. I describe a variety of work such as removing damaged parts, metal straightening, filling inequalities, grinding, coating layers of paint and assembly. At the end make the final calculation of the cost of repairs, time allocation, the result of labor-cost estimate for repairing the vehicle and compare all the costs estimated at the beginning.

Modern methods of tube- and profiles bending
Zouhar, Ondřej ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
The project elaborated in the framework of Bachelor's study presents a survey of modern methods in the field of bending tubes and profiles. On the basis of literary evidence relating to the bending of tubes and profiles the list was created to summarize all the currently used modern technology in this field. The work covers the theoretical part of the time horizont of the oldest methods of bending to the present methods. In the theoretical part are given the most modern machines used to bend tubes and profiles.
