Production of forging piece "Spanner"
Vávra, Jan ; Kopřiva, Miloslav (referee) ; Novotný, Karel (advisor)
Projects developed within the bachelor's degree in Mechanical Engineering, presented a proposal technology forged wrench - the hot-rolled steel bars 11 523.0. The thesis also compares the past with conventional methods of production and considering the new technological process of manufacturing. Based on the literature studies about fitting and calculations, was chosen to die forging hammer KHZ 2 A (producer ŠMERAL Brno, plant Hronov), with nominal energy of 20 kJ working pressure of 16 MPa and 30 kW electric power.

Fatigue properties of structural steel 11 523
Kudelka, Martin ; Kohout, Jan (referee) ; Věchet, Stanislav (advisor)
This bachelor thesis studies the mechanical properties of steel 11 523 in the state after normalization annealing. Its purpose is an assessment of the structure in material and determination of static and fatigue characteristics. In the theoretical part of thesis, there is explained, how to divide and mark kinds of steel. There is also a mention about basic parameters of material and the main attention is paid to fatigue and its laws. The metallographic analysis, tensile test and the fatigue test were realized in the experimental part of thesis. Experimentally determined values were compared with data in the literature.
