Technology of radial bearing steel cages production
Jabůrek, Petr ; Špaček, Jindřich (referee) ; Rumíšek, Pavel (advisor)
The project conceived within engineer’s studies of branch 2303T002 is subbmitting a proposal for radial bearing cage produce technology. It is also subbmitting a design solution to functional parts for blanking the “windows” and coining the “locks”. The cage will be made from sheet steel 11 300.29. This cage should replace the current one machined from the brass Ms 58 Al. According to the literary research and development experiences of the company ZKL Brno, a.s., two pairs of tools were designed. First one for blanking the “windows” and second one for coining the “locks”. Blanking punch, blanking die and coining punch will be made from the steel 19436, coining die will be made from the steel 19312. Heat-treating process will be accomplished according to the enclosed drawings. Both pairs of tools will be mounted in the press LENR 63 AU (manufactured by the company ŠMERAL Trnava), with nominal force 630 kN.

Technology groove manufacture on a shell clamping element
Brdečková, Zuzana ; Žák, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
The aim of the thesis is the design of the production process and tools for production of two grooves in coats of concrete clamp. Shell anchors are made of longitudinally welded stainless steel tubes 17 240. The size of the production of all types of shell of concrete clamps is 18 000 PCs per year. The number and the dimensions of grooves in the coats of anchors were determined on the basis of a practical verification. To the present day the grooves are made by cutting on a band saw, which is little productive and on finishing operations demanding way. The grooves in the coats of anchors will be newly manufactured by technology of shearing, which was a literary study. On the basis of the calculations was selected for the production a hydraulic press of CUPS 25 D. The grooves will be produced on the newly designed shearing tool. Work is carried out by technical-economic evaluation, which compares the current technology of production with the newly proposed technology. Part of the thesis is drawing documentation of coats of concrete clamps of all dimensions and drawing documentation of shearing tool.

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.
