Manufacturing of the Wall Bracket Bicycle
Sikora, Marek ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This master’s thesis presents a proposal for the technology of manufacturing sheet metal part, which is a part of a bicycle wall bracket. The component is made of steel sheet ČSN 11 325 with subsequent surface treatment by galvanizing. Due to the chosen method of manufacturing with a progressive stamping die, the research part is focused on the technology of shearing and bending. Technological calculations were performed for the most suitable production variant, on the basis of which a mechanical press ANDRITZ Metals with the designation KSTU 2000-20-4G-PSE was chosen. Furthermore, the design of the tool itself is presented, which is substantiated by drawing documentation. At the end of the work, a technical and economic evaluation of the produced series of 300 000 workpieces per year is calculated.

Manufacturing of part of garage automatic door lock by compound tool
Vaverka, Ivo ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
This master’s thesis created in the master studies of the M-STG Manufacturing technology is focused on the manufacturing of a part of a garage automatic door lock by a compound tool. The part is made of a rolled steel coil of the S275JR material with the thickness of 2 mm. The number of parts manufactured per year equals to 600 000. Literary studies deals with the issues of cutting and bending. On the basis of the most advantageous manufacturing variant and technological calculations the compound tool is designed. As a working machine the eccentric press LEK 160 is chosen. In the economical evaluation part, the calculations to finding out when the manufactory becomes profitable are carried out.

Design of reinforced concrete structure with respect to fire resistance requirements
Pivodová, Alena ; Klodner, Jan (referee) ; Perla, Jan (advisor)
The diploma thesis deals with an analysis of internal forces of B4 reinforced construction of an office building. Analysis takes into account interaction with subsoil and when designing structural parts of the building, different requirements for fire resistance of a structure are taken into account. A Dlubal RFEM 5.17 program was used for finite element analysis, and model functionality verification was performer by using a summation of moments method. The thesis deals with the design and assessment of a point-supported slab, column, inner and external walls.

Overpass bridge across the highway
Černý, Pavel ; Šopík,, Leonard (referee) ; Nečas, Radim (advisor)
The topic of this thesis is detailed design of the supporting structure of a bridge. Three variants are designed. The structure is designed as a single beam bridge of 6 spans. The calculation of load efects make in software MidasCivil 2019 and Scia Engineer 18.1. The subject of the expertise of the structure is service limit state and ultimate limit state. For evaluation of cross sections is used MS Excel. Both design and relevant drawing documentation of the bridge deck and substructure. The design and assessment are according to the europien standards.

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.

Construction design hydraulic press brake
Stránský, Jaroslav ; Holub, Michal (referee) ; Pavlík, Jan (advisor)
This thesis is divided into several chapters. First two chapters after introduction are written as search type. In next part I devoted to detailed design of functional mechanisms of linearly moving parts of press brake. For the construction of stop mechanism I dealt with conversion types as ball screw, pinion with rack and timing belts. There is also quite thorough calculation part in ball screw and pinion with rack issue. I have also dealt with the necessary bending force and then designed hydraulic cylinders. Elaboration of machine frame with safety features is included.

Production of holder
Andris, Tomáš ; Podaný, Kamil (referee) ; Lidmila, Zdeněk (advisor)
The project elaborated the design of technology production of the holder used for fixing pneumatical cylinder at the testing rack. The holder is manufactured from 2 mm thick sheet metal made of structural steel 1.0038 in a production series of 6,000 units/year. After considering the individual production options, shearing in transfer die and simple bending die were selected. Based on the literature study of shearing and bending technology, an optimal production process of the holder was proposed. After technological, structural and verification calculations, the tools were designed, and the technical documentation was prepared. For the production of the holder was selected eccentric press LEXN 100 C made by Šmeral Brno a.s. This press meets the requirements of the forming force, forming work and the dimensions of the tool. According to the calculated economy of production, the production costs of one holder were determined with a 30 % profit to 97 Kč. The turning point when production becomes profitable was calculated to 4 454 units.
