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.

Optimization of the process of pressing balls into the injector body
Kadlecová, Petra ; Frýza, Josef (referee) ; Brandejs, Jan (advisor)
This thesis is focused on a pressing station as a part of the assembly line in the Bosch Diesel plant in Jihlava. The station provides sealing of a hole in the injector body by ball pressing in. By using several tests the thesis finds out a reason of large amount of waste pieces, checks how can pressing-speed change or lubricant change infuence the pressing process itself and compares capabilities of hydrolic vs. electric pressing machine.

Preparation processes and properties of porous zinc material
Moleková, Kristína ; Březina, Matěj (referee) ; Hasoňová, Michaela (advisor)
Bachelor thesis occupy with preparation of porous material from zinc powder by cold pressing, cold pressing followed by sintering and hot pressing. This thesis contain both preparation of bulk material, and charakterization of materials based on the compaction process conditions. Impact of pressing process on subsequent progress of sintering and final attributes of materials is evaluated. Bulk material is characterized considering to structure, porosity, and physical-mechanical properties. Properties of final metarial will serve to optimize conditions for process of pressing and sintering.

Design of pressing machines for manifold assembly of condensers in car air-conditioning unit
Juriga, Jakub ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
The diploma thesis deals with the design of pressing machines for manifold assembly of condensers in the car air-conditioning unit. The problem of the current assembling process is its inefficiency. Semi-automated assembly using pneumatic pressing machines eliminates this problem. In the theoretical part the air-conditioning components, current state of assembly and calculating base of pressing are described. In the practical part the test of pressing force was conducted. Based on this test, the design of four pneumatic pressing machines was accomplished. In the final part of the work, evaluation of the whole project is provided.

Control of the pneumatic press
Lichosyt, Tomáš ; Pásek, Jan (referee) ; Štohl, Radek (advisor)
This thesis deals with the creation of the control program according to the standard 88. Document contains a brief description of the security features of the model of the pneumatic press. It also focuses on the description of the standard 88 and its subsequent implementation on the pneumatic model. Next part of this document describes the development environment FactoryTalk Batch, which will be used for batch control. The next is a description of the phases formed in RSLogix 5000, configures and recipe created in the FactoryTalk Batch software. The last point is the creation a product for pressing and stamping.

Evaluation of Power Efficiency of Radioactive Waste Management Technologies Used in the Czech Republic
Penzinger, Pavel ; Varmuža, Jan (referee) ; Katovský, Karel (advisor)
This thesis deals with the evaluation of power efficiency of technologies for the radioactive waste management used in the Czech Republic. Thesis is divided into two main parts – theoretical part and a practical part. Theoretical part of the thesis deals with a brief description of the organization connected with radioactive waste operating in the Czech Republic and storage of low and intermediate level waste in the Czech Republic. This is followed by various kinds of radioactive waste division according to Czech legislation and regulations of the International Atomic Energy Agency. There is also a description of the most used technologies and methods o of radioactive waste management technology used in the Czech Republic and world. Practical part contains specific evaluation of energy efficiency of each technology for the radioactive waste management. Each evaluation contains the energy efficiency of production use materials and transport. Evaluates are technologies used consistently and for sufficient quantities. Energy efficiency is describe from the place of origin of radioactive waste, which is the Nuclear power plant Dukovany, Nuclear power plant Temelín and ÚJV Řež, a.s. The end of description is the repository site of radioactive waste Dukovany for radioactive waste from nuclear power plants or disposal site Richard for institutional radioactive waste.

Optimalization of parts bonded by hot crimping
Liškář, Ladislav ; Řiháček, Jan (referee) ; Lidmila, Zdeněk (advisor)
The thesis describes the procedure for verifying the conceptual ideas of the company. Design and production of prototypes, testing and evaluation, quantifying savings. Two variants of crimped bond were chosen. For each was length of shaft changed to three and four crimped grooves. These prototypes were tested in two static and one dynamic tests. Recommendation for company is continue with other phases of development for shaft with four grooves.

Design of single-purpose machine for pressing bearings in pulleys
Roupec, Michal ; Továrek, David (referee) ; Bradáč, František (advisor)
Purpose of this thesis is to make constructional modification of single-purpose pressing machine for Huisman Konstrukce, s.r.o. company. Present machine is non-operational and not enough powerful for present requests of workshop. Intended modifications are to describe present condition of machine, find present requirements and design simple modifications. All modifications are checked by calculations and sketched in shop drawings. There were also made alternative options of modification to show machine more versatile and automatic.
