Technological project of production line for plastic windows
Nejedlý, Jindřich ; Heinl, Zdeněk (referee) ; Rumíšek, Pavel (advisor)
This master’s thesis focuses on rationalization of production line for plastic windows production in RI OKNA a.s. (Inc.). Evaluation of production line’s current estate is being done as well as weak point detection. On these bases some new variations for improvement are being suggested. The winning variation is drown up into the technological project and put through an economical evaluation.

Technology of thrust bearing steel cages production
Jež, Marek ; Štroner, Marek (referee) ; Rumíšek, Pavel (advisor)
JEŽ Marek: Technology of thrust bearing steel cages production . Diploma assert of daily magisteral´s studies, study programme – Industry. The branch manufactoring technology, 2 end form, level 2 – summer semester, study group 50 / 51, academical year 2007 / 2008. FSI of Brno University of Technology, department of forming and plastics, May 2008, 78 pages, 54 pictures, 6 supplements. The main theme of the Diploma Theses is the technology of production of tin cages for axial spherical-roller bearings. The given matter includes the production of tin cages for axial spherical-roller bearings – by traction, cutting, punching and calibration. For the chosen representative, i.e. bearing with marking 29 336 M I suggest the substitution of tin cage instead of the brass one. The component (cage) is made of the sheet iron 11 300 of 4 mm thickness, the basic semi product is the sheet panel with the size of 360 x 4 x 3000 mm. In solving the given matter, it is started from the fact that the current state of the cage is still under development. The aim of the Diploma Thesis is to choose the representative, suggest the appropriate technological progress, proposing the engineering design of functional parts of the tool for punching the holes/windows including the necessary calculations and workshop graphical documentation.

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 project and layout for holder
Skrýval, Tomáš ; Novotný, Karel (referee) ; Rumíšek, Pavel (advisor)
The project conceived within engineer‘s studies of branch 2303T002 is showing holder produce technology using by the company UniTools Press CZ Valašské Meziříčí. This holder is a part of car seat-adjusting system dedicated for Peugeot 308. According to the literary research, next part of this project is submitting two diferent solutions of produce technology and then it chooses the best one. The best one is chosen with the help of weight values table. The holder is produced in associated tool on press Arisa 400 with nominal force 4000 kN. The holder is manufactured from the roll of sheet steel S355MC (thickness 3mm). In the last part this project is suggesting the modification of produce technology in order to increase tapping tool working life and to increase the production productivity. Keywords: The steel S355MC, tapping, associated tool. y

Production of the component "Lid"
Vyhnanovský, Jaroslav ; Rumíšek, Pavel (referee) ; Žák, Ladislav (advisor)
This project developed within the Bachelor study of Engineering Technology proposes a technology component “Lid” made of1 mm thick sheet metal ofmaterial11 375(1.0038). The component will be made on a combined roll forming machine. A mount with two pillars will be used for the production, which will be located in an eccentric press LEN 40C by TOMA Industries Ltd. based in Trnava, Slovakia. The nominal press force is 400kN. Trimming punches, broaches, blanking dies and bending punches are made of tool steel, grade194....

Technology of the frame base production
Havliš, Lukáš ; Špaček, Jindřich (referee) ; Rumíšek, Pavel (advisor)
The bachelor's thesis deals with technological project of frame base production. Since a component designated as a wing base is produced together with this base, the thesis is also concerned with production of this part. Methods of sheet metal forming are analyzed in the theoretical part. Methods used during production pressings - such as cutting, bending, punching and calibrating – are concerned. Practical part of the thesis comprises description of produced segments and their location and function within the assembly, choice of material, shearing layout and choice of forming machine. Economic evaluation of segments production has been performed in conclusion. As soon as material has been chosen (11 343 material has been chosen with regard to low requirements for assemblies), calculation of cutting and bending force has followed. Forming machine (LE 250 has been found the most suitable one) has been chosen based on results of the necessary forming forces, after evaluation of cutting layout and demand on the sheet metal coil. Two options of components production have been compared in the economic evaluation. Method of production in a common tool has been found more cost-effective.
