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.

Typical features of progressive shearing
Žanda, Jakub ; Harant, Martin (referee) ; Štroner, Marek (advisor)
The bachelor thesis first covers the basic theory of shearing technology, its process and the quality of the shearing surface. Then it focuses on the technology of progressive shearing. Its advantages and disadvantages are thoroughly described, and furthermore it is compared with other shearing methods in cutting dies. This is followed by a description of the individual components of the die and an explanation of their function and use. The material requirements of the tools are discussed and their heat treatment is presented. The last part is focused on the evaluation and contribution of this technology.

Production of carpentry joints
Kliš, Vojtěch ; Žák, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
The thesis deals with the design of the technology for the production of the galvanized sheet. It is a carpentry joint that serves for joining wooden structures. The work is focused on metal forming, namely cutting technology. Based on the production series of 30,000 pieces/year, the shape and dimensions of the part, the method of shearing was chosen for production. Furthermore, the necessary technological calculations were performed. The tool consists of standardized components that have been selected based on the standards. For production was chosen eccentric press S 160 E from the company Šmeral Brno a.s. The price of one component is CZK 9.

Specifics of Main Components of Simple Blanking Tool
Kašpar, Jaroslav ; Dvořák, Milan (referee) ; Peterková, Eva (advisor)
The thesis elaborated Specifics of Main Components of Simple Blanking Tool. The thesis is divided into 5 basic parts. The first part deals with the issue of cutting tools in general. The second one introduces a simple blanking tool. The third and most extensive part describes in detail the selected main components of blanking toll. The fourth part contains possible ways to increase the life of main components and the last part is summary of the most frequently used materials for these functional parts.

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.

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.
