Design of bending tool for V-bending sheet
Zedníček, Zbyněk ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The object of the bachelor work is the design of the bending tool for V-bedning. The sheet segment of the shovel of the conveyor belt is assigned. The introductory part deals with the problems of preparation of the semi-finished product and the analysis of possibilities of bending technology. Then the suitable technology is chosen. In the next part there are introduced technological aspects of the design of the piece of the sheet component and there are made computatious for the design of bending and the preparation of the semi-finished product, minimum and maximum bending radius, suspension, bending power and work, computation of the straightened length of the component and the total consumption of the material. The design of the tool for bending of the segment is made on the basis of technological computations. Economical assessment of the production is made, material costs for the tool bending are introduced and the selling price of the shovel of the conveyor belt is determinated. The whole course of the design is summarized in the conclusion.

The holder manufacturing
Isakidis, Petr ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The aim of the thesis is to propose a suitable technology for a production of a licence plate holder and motorcycle trafficators, which are from the thin metal plate. Production series is 600 000 items. The chosen material is 11 321.1 in form of the roll of steel. The thesis comprises of the theory of the topic of shaping, the proposal of an engineering solution including technology concept of calculations and choosing of a suitable option. The structural design of a procedural cutting machine is created by a modeling program CATIA V5, which was also a suitable instrument for technological calculations.

Testing bonded steel sheet coated with zinc
Zedníček, Zbyněk ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The aim of this master´s thesis is the design chosen for testing bonded joints on the specified galvanized steel sheet in laboratory conditions and obtaining parameters of bonded joints for application in industrial practice. Basic tests for testing bounded joints were presented in the work. Subsequently, two tests were selected and verified in laboratory conditions. The result of these tests are specific numerical values that were compared with values gained during tests linking method clinch.

Design of Park Bench
Soušek, Vít ; Rajlich, Jan (referee) ; Sládek, Josef (advisor)
This work deals with design of park bench. The first part analyzes a design of this element of street furniture in terms of history and the present time. The second part deals with own design solution. The main purpose was to design an elegant modern bench that will revive a look of public spaces of the contemporary city by interesting way. The bench was designed with respect to aesthetics, ergonomy, manufacturability and other essential aspects of industrial design.

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.

Static analysis of one joint of timber structure
Sedlák, Petr ; Gratza, Roman (referee) ; Kytýr, Jiří (advisor)
This diploma thesis deals with the numerical modeling of the nail joint of the timber roof structure and it is based on the already realized physical experiment. Totally twelve various solutions, where the isotropic and ortotropic characteristics of the spruce timber and steel components change, have been created. The final values of the joint shift obtained by using of the numerical modeling are compared with results of physical experiment. Program system ANSYS is used.
