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.

Construction and shearing tool production
Šincl, Josef ; Žák, Ladislav (referee) ; Štroner, Marek (advisor)
The bachelor work describes construction and production of the progressive tools, which is used for production of lugs for car Škoda Octavia combi. The lugs are made from material number 1.0396. There were elaborated research from the field of shearing and bending. These technologies were used for production of desired part. In the instrument are made both left and right parts, which are mirror. There are also solved different difficulties in the construction. The instrument should have life cycle 3 000 000 of produced parts. The instrument is used in the 160 tons eccentric press of brand Dirinler, model CDCS P81. To the eccentric press is connected automatic straightener and dispenser, so that there is not necessity of service. The instrument is given yet and is involved in the full operation.

Stress-strain analysis of winepress frame
Vaculka, Miroslav ; Fedorova, Svitlana (referee) ; Novák, Kamil (advisor)
This bachelor’s thesis deals with stress-strain analysis of winepress frame. The press is made of self help. No analysis has been performed for it yet. The thesis contains its detailed research, then basic research about other winepresses and research in the Mechanics of Materials. A computational model was set and stress-strain analysis was done in an analytical approach and numerical approach using the program ANSYS. Everything was evaluated in the discussion of the results, including the achievement of the safety factor to limit the state of elasticity. A system approach was used in the entire bachelor’s thesis.
