Drive system by serial connection of rotary hydromotors
Pokorný, Pavel ; Knoflíček, Radek (referee) ; Omes, Jiří (advisor)
The thesis deals with the problem of large-capacity manipulation of large forgings with forging manipulator. It describes current techniques, their characteristics, advantages and disadvantages. Based on the analysis of these techniques, the thesis introduces design of the connection of the hydraulic circuit for the drive of the traveling traction wheels of the forging manipulator QKK 100 by ŽĎAS a.s. focusing on simplicity, trouble-free operation, efficiency, economy, change of speed and torque, and possibility of modification according to the current load.

Workshop hydraulic press
Budík, Tomáš ; Tůma, Jiří (referee) ; Omes, Jiří (advisor)
This work deal with workshop hydraulic press to moulding heated rod blanks with the possibility of adjusting the main pressing cylinder depending on the operating technology. We analyze issues of design and calculation of the hydraulic circuit and the hydraulic, electrical and electro-hydraulic components. In the end we solve the elastic deformation analysis of the machine using the finite element method.

Damascus steel production
Gajdošík, Matej ; Harant, Martin (referee) ; Podaný, Kamil (advisor)
Bachelor thesis deals with production of Damascus steel. Literary pursuit deals with methods of production, with closer elaboration of free forging technology, suitable material properties and work procedures during forging and etched specimen preparation. In the practical part of the work, production of two forged pieces consisting of 15n20, 80CrV2 and 1095 steels was documented. Subsequently an etched specimen was prepared to assess the success of the experiment. Finally, a knife was made from the selected forged piece.
