Use of modern technologies in the production of flat sheet metal parts
Kohoutová, Zuzana ; Podaný, Kamil (referee) ; Špaček, Jindřich (advisor)
The final work elaborated in the scope of master's studies of the branch 2303T002 submitted use of modern technologies in the production of flat sheet metal parts from the material 11 373. Work is set for cold shaping of metal by means of cutting. Production on sequence shearing tool is based on series 350 000 pieces per year. Universal hydraulic press CUPS 63 DEU with shearing force 630 kN is selected for realization. Work is also focused on the production of the same components using plasma, laser and water CNC equipment and the subsequent economic evaluation of all variants of the production. In enclosure there is drawing documentation for cutting tool.

Proposal for the production of variants of flat sheet metal parts with holes
Fabík, Pavel ; Hušek, Martin (referee) ; Špaček, Jindřich (advisor)
FABÍK Pavel: Proposal for the production of variants of flat sheet metal parts with holes The project elaborated in frame of bachelor’s study branch B2307-00 submits a design of technology components from sheet metal with holes - parts of steel 11 320.1 (specified by INGE Opava). On the basis of literary study problems of production of the components were designed and compared two methods of production. Cutting on the combined cutter attached to the double-stand hydraulic press type Tleff (designed by KIT Invest Ltd. for the Trading) witch 4000 kN pressing power. The cut parts of cutting tool are made of material 19 312 (as designed by Brano). Laser cutting is done on a machine AMADO FO-3015 (in the company Dender).

The manufacturing of electromotor covering
Stejskal, Luboš ; Špaček, Jindřich (referee) ; Podaný, Kamil (advisor)
This project has been presented for the bachalor branch of study, B2307, it shows the proposal of technological and production process for deep drawn parts. They are produced from the steel (11305). Due to the production volume of 100.000 pieces per year, it was proposed to implement the production process. It basis of the literature study which describes the potential pitfalls of deep drawn technology. After control a technological calculations it was decide to choose the stamping machine CTC 250 (manufactured by ŽĎAS, a.s.).The deep drawn tool has been designed in order to use the maximum capabilities of this stamping machine, specially the upper ejector and the lower holding device.

STAINLESS PART SHEET METAL FORMING
Rozmahel, Vladimír ; Podaný, Kamil (referee) ; Špaček, Jindřich (advisor)
The project elaborated in frame of Bachelor’s studies branch B2307. The project is submitting design of technology production of the flanged workpiece made of stainless steel 17 240. Based on results of initial study of the drawing topic, proposed solution was based on Guerin method split to three stages. The punch is replaced by rubber pad of rougness equal to 80ShA. The die is made of instrumental steel CSN 19 314.

Proposal for the production of variants of flat sheet metal parts with holes
Chaloupková, Lucie ; Peterková, Eva (referee) ; Špaček, Jindřich (advisor)
The final work elaborated in the scope of bachelor studies of the branch B2307-00 submitted variants of production for flat sheet metal parts with holes. In work there are two variants of production of one particular part namely: Production on sequence shearing tool and production by means of plasma CNC machine. Particular part is designed for quantity 120 000 pieces per year. Shearing machine S250 with shearing force 2500 kN is selected (manufacturer Smeral a.s.Brno). In the work there are implied necessary calculations for both variants including economical evaluation and criteria for practically implementation.

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.

New trends of material cutting
Uttendorfská, Magdalena ; Špaček, Jindřich (referee) ; Peterková, Eva (advisor)
The thesis is focused on formation of a survey of modern methods of semi-product division in the area of forming technology. The first part of the thesis deals with material division conventional methods as cutting-off, clipping, refracting, cutting and sawing. These methods have already reached their utilization maximum. Their perfection is possible to be made e.g. by means of modern cutting materials. The next part is concentrated on material division special methods (oxygen cutting, laser, plasma and cutting by water jet) with presentation of their brief description. These methods have recorded the technology move ahead.

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.

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.
