Hydroforming machine for non-ferrous material tubes
Ocelík, Jakub ; Holub, Michal (referee) ; Knoflíček, Radek (advisor)
Master`s thesis deals with unusual high-pressure-fluid forming technology – hydroforming. There are discussed factors, which are affecting forming process, and there are made conclusion of it for machine design process. There is also made an evaluation of tube hydroforming technology in nowadays. The objective of thesis is to design new forming machine for tube hydroforming and for use in bicycle frames design. The machine is to be determined for manufacturing series up to 1000 pieces. Based on calculations and discussion of hydroforming technology, the best design solution is chosen. Machine is designed as modular conception with pressure multiplication of forming fluid right in die cavity. There is no need to use high pressure pump for forming fluid, used in common machines for tube hydroforming. This leads to cost reduction and so the objective of thesis is accomplished.

Using of liquids in forming technologies
Vraštiak, Michal ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
This work submits actual literary work about technologies, which use a liquid such as forming media. Here are listed their basic principles of methods: hydroform, hydromechanical drawing, Wheelon, Asea, high speed forming, tube hydroforming, Pillow forming, Flexform. Work includes their evaluation, examples of practical use and analysis of advantages and disadvantages.
