Modifying of a passenger car door hinge
Čermáková, Klára ; Kozman, Zdeněk (referee) ; Píštěk, Václav (advisor)
This thesis introduces issues of passenger car side-door hinges. Practical part of this thesis deals with modifying the current low-cost side-door hinge for Edscha Automotive Kamenice s.r.o. First, material was chosen to decrease weight while maintaining the required mechanical properties. Then follows the detail design of the hinge model, which was created in the software program Catia. Heat and surface treatments are described. Both treatments ensures the hinge's final features. To verify the strength of the hinge, tensile and sag test was simulated in Ansys. Subsequently, record from the consultation of the hinge's manufacturability in series and the hinge’s cutting plans are provided. At the end of the thesis, the assembling procedure is suggested. Final part of the thesis compares the developed low-cost hinge against two similar side door hinges.

Design of a bending tool for U-bending of sheet metal
Kyselá, Lenka ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The Bachelor thesis entitled The proposal of bending tool for U-sheet-bending, worked out under the bachelor studies of B-STG branch, presents a proposal of technology of production of a batten in U-form. The assigned part is made from construct steel S235 JR of 2 mm thickness. The proposed bending tool is designed to be used for production of a batten from galvanized steel sheet for assembly of shelves in consumer industry. This proposal of bending tool for U-bending includes technological calculations, drawing documents and technical-economic evaluation.

Production of the fixing element
Hřebíček, Robert ; Jurenka, Vladislav (referee) ; Lidmila, Zdeněk (advisor)
Fixation element consolidates filtration cage to filter. For production of this element 3 mm thick steel 11 373 was used. The production is estimated to 24 000 pieces per year. From many different possible production technologies the method of cutting followed-up by bending was chosen. Since it is impossible to implement these methods into one tool it is carried out step by step. For all steps the construction and technological calculations were carried out and from them templates were formed. For production was used company equipment (press LEXN 100C, shears NTE). Also production costs were calculated and annual profit was graphically represented. The production is profitable since 16 843 pieces are made per year.

The manufacturing of sheet metal part by blanking technology
Suchomel, Lukáš ; Špaček, Jindřich (referee) ; Peterková, Eva (advisor)
The master’s thesis elaborates an optimum proposal of the production technology of a cutting – a part made of steel plate 11 320.3. The theoretical part represents the problematic issue of cutting technology and on the basis of this part was designed a production of components in processual tool. The processual tool is composed of normalized components and is resolved by using a easel, which is attached into the eccentric press LEXN 100 C (producer Toma Industries) with the nominal drawing force of 1000 kN. The press was chosen on the basis of technological calculations. The work contains necessary calculations, economical evaluation and design documentation of the cutting tool for the components production. The last part contains the technical and economic evaluation of the recently designed technology.

Proposal for the production of variants of flat sheet metal parts with holes
Hamáček, Petr ; Vonka, Vladimír (referee) ; Špaček, Jindřich (advisor)
HAMÁČEK Petr: Proposal for the production of variants of flat sheet metal parts with holes. The final work of bachalors studies, 3th grade, academic year 2008/2009. FME VUT in Brno, Institute of manufacturing technology, department of metal forming and plastics. Bachelor work elaborated in the scope of bachalor studies of the branch B2307 submitted variants of production for flat sheet metal parts with holes. Theoretical part of the thesis is pointed to theory of cutting and description of personál cutting process. Shearing machine LEPP with shearing force 1000 kN is selected. Blanking puch and blanking are made from 19 class alloyed instrumental steels, heat treated according to graphical documentation. Cuttingin machine is using standardized components and it is solved by particular frame into eccentric machine. In the work there are implied necessary calcullations for both variants including economical evaluation.
