Bulk forming technology of connecting pin
Trnka, Filip ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The project elaborated in frame of engineering studies branch M-STG proposes a technology of connecting pin – structural steel 11 320 5R. The technological calculations were performed and the production procedure was devised on the basic on the literary study of cold bulk forming with concentration on the extrusion and upsetting. Forming machine was design HATEBUR BKA-3 with a nominal power 1800 kN. The component is made in four forming operations. Extruder will be made from tool steel 19 830, extrusion die from tool steel 19 830 and clamp ring from tool steel 19 740.

Simulation of rolling operation using explicit FEM
Bezrouková, Martina ; Zemčík, Oskar (referee) ; Zouhar, Jan (advisor)
The purpose of this work is to introduce explicit finite element method (FEM) and to familiarize with commercial software tools witch are capable to perform simulations. The technological conditions and the scope of application of roller burnishing are described in subsequent part. The simulation model of roller burnishing was created. Software ANSYS LS-DYNA was used to make computations. The results of simulation and technical and economical benefits of roller burnishing are presented in the conclusion.

Production single parts "Bracket" from sheet metal
Buchta, Petr ; Lidmila, Zdeněk (referee) ; Žák, Ladislav (advisor)
The project which was developed in the framework of a bachelor's degree submits a proposal of production of steel material 11373, shearing and subsequent bending. The main topic of this thesis was to create tools that would allow a simple and inexpensive production of components. Tools have been designed and manufactured on the basis of literary studies issues, associated with shearing and bending. The function parts of the instruments are made of tools steel class 19.

Forming technology production of window hanger.
Štejnar, Radek ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
An objective of the bachelor’s thesis is the solution of forming technology production of window hanger by means of backward extrusion and elaboration of study concerning cold bulk forming. Required component is made of material ČSN 41 1320 5R and rounded chock with dimension of 14,6h9 - 25,3 mm is selected as semifinished product for production. Generally 2 alternatives of technology process were assessed whereas technological and strength calculations are executed utilizing computing support of TVÁŘENÍ and OPTIM97 software. Component is produced within 4 operations including cutting of wire. Multi-stage cold forming press TPZK 25 made by ŠMERAL a.s. Brno producer was chosen for designed technology. Production tools are made of high speed tool steel 19830.
