Production single parts "HOLDER"
Wagner, Jan ; Špaček, Jindřich (referee) ; Žák, Ladislav (advisor)
The diploma thesis is elaborated within frame of masters study programme 2303T010. The work is submitting design of technology production of the drawn part – the holder. The work is based on the study of problems of the deep drawing process and related calculation was designed drawing in instrument with holder according to drawing documentation 2-5M68-12/00. The lower ejector is using for extrusion component. The drawing instrument make use of standardised components and it is solving forms of customary stool close-set on the crank drawing inclinable press LESP 63 A (producer ŠMERAL Brno, plant Trnava), with nominal tensile force 1000 kN. Drawing punch and drawing die are produced from alloyed instrumental steel 19 573, heat-worked according to drawing documentation.

Proposal technology of production scheet-metal part of car body
Sviták, Martin ; Špaček, Jindřich (referee) ; Žák, Ladislav (advisor)
The Master’s Thesis is focused on stamping of sheet metal parts. The analyzed part is a structural part of an automobile body. The part is made of DC04 (cold rolled mild steel) material. The annual pruduction volume is 10.000 pieces. Theoretical background research is a knowledge base for design of tooling that can produce parts which meet quality requirements. There are three technological processes proposed in the Thesis. An economic analysis identifies the optimal technological process for the production volume. The thesis contains a complex analysis that confirmes material formability. Computer simulation verifies the part design, material and technological parameters of the forming process.

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.

The manufacturing of shallow drawing part by rubber
Klepáč, Patrik ; Špaček, Jindřich (referee) ; Podaný, Kamil (advisor)
An object of this master thesis is the proposal of variants solving a manufacturing of required part and the selection right technology for single part production of required part from stainless steel 17240 (DIN 1.4301). At the first part of this thesis is briefly reviewed conventional forming and at rest of this thesis is closely reviewed the technology using the elastic tools (rubber, urethane), hydroforming technology and design of proper tool for required part. At the end of this work will be release economics estimation of fine technology and designed tool.

Production single parts from sheet metal on two-station tool
Vrána, Petr ; Špaček, Jindřich (referee) ; Žák, Ladislav (advisor)
Projects developed within the bachelor's degree in engineering technology (B3S-K Engineering) technology by design sheet metal parts 11 373.1 on a combined tool. Based on the literature studies about cutting, bending and stretching has been proposed several variants of the production of specified parts to be produced entirely in a single tool. The proposed tool is clamped in the eccentric press PE 100 D firm ERFURT with a nominal force of 1000 kN. The functional parts are made of tool steel, 19 436 heat-processed according to drawings. Punches are made as a split because of interchangeability and easy repairability.

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.

Proposal pressing tool for sheet metal part
Ručka, David ; Peterková, Eva (referee) ; Špaček, Jindřich (advisor)
The in the framework of Bachelor Studies developed project presents a technology- proposal for the production of a pressing tool for the manufacturing of parts from the sheet steel S500MC. On the basis of a literary survey of problems of the component manufacturing through shearing and calculation, cutting in the phase-shearing tool was proposed. According to the shape of the component, a thirteen-steps cutting processes was proposed, two steps of which are free and open to subsequent changes that can occur in the process of shearing. Normalized components from the catalogue company FIBRO were used in the construction of the pressing tool. The press GERB EDELHOFF 80 t was selected as the working device.

Proposal for the production of variants of flat sheet metal parts with holes
Kohoutová, Zuzana ; Podaný, Kamil (referee) ; Špaček, Jindřich (advisor)
The final work elaborated in the scope of bachelor studies of the branch B2307-00 submitted proposal of variants for production for flat sheet steel parts with holes from the material 11 373. Work is set for cold shaping of metal by means of cutting and production by means of plasma CNC machine. Production on sequence shearing tool is based on series 150 000 pieces per year. Shearing machine S250 (manufacturer Šmeral Brno a.s.) with shearing force 2500 kN is selected for realization. Work is also focused on the production of the same components (valve) using a CNC plasma equipment and the subsequent economic evaluation of both variants of the production. In enclosure there is drawing documentation for cutting tool.
