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.

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.

Design of stamping tool for sheet metal part
Ručka, David ; Žák, Ladislav (referee) ; Špaček, Jindřich (advisor)
The in the framework of Master’s Studies developed project presents a technology- proposal for the production of a pressing tool for the manufacturing of parts from the sheet steel DD13. On the basis of a literary survey of problems of the component manufacturing through shearing, bending and the studies of heat treatment and applications of covering coat and calculation, manufacturing in the phase-shearing tool was proposed. The press GERB EDELHOFF 80 t was selected as the working device.

Production of cold forging parts
Jedovnický, Jan ; Samek, Radko (referee) ; Špaček, Jindřich (advisor)
A project developed during a magister´s study of a program M-STM Mechanical engineering and industrial management brings in a proposal of a technology of cold forging part out of 12 040 steel. The forging on a multi-stage processual automatic machine TPZK 25 with nominal forming power 5000 kN was projected based on consultations, study of literary resources a calculations.

The manufacturing of sheet metal part by blanking technology
Suchomel, Lukáš ; Špaček, Jindřich (referee) ; Peterková, Eva (advisor)
The master’s thesis elaborates an optimum proposal of the production technology of a cutting – a part made of steel plate 11 320.3. The theoretical part represents the problematic issue of cutting technology and on the basis of this part was designed a production of components in processual tool. The processual tool is composed of normalized components and is resolved by using a easel, which is attached into the eccentric press LEXN 100 C (producer Toma Industries) with the nominal drawing force of 1000 kN. The press was chosen on the basis of technological calculations. The work contains necessary calculations, economical evaluation and design documentation of the cutting tool for the components production. The last part contains the technical and economic evaluation of the recently designed technology.

Suggestion of convenient technologies of production for submitted flat sheet metal part
Chaloupková, Lucie ; Podaný, Kamil (referee) ; Špaček, Jindřich (advisor)
The project is elaborated in frame of engineering studies branch 2303T002. The project is submitting suggestion of convenient technologies of production for submitted flat sheet metal part 11 375. There are proposed a number of variants of production method, namely: production on sequence shearing tool, production by means of plasma machine, laser machines and machines for watejets cutting. Particular part is designed for the production quantity of 380 000 pieces per year. Based on the literary study of the shear and calculations, there were designed shearing tool for given part. For this tool the press CDCH 3000 P was selected (producer HESSE+CO Maschinenfabrik GmbH), with nominal force 3 000 kN. In the work there are included necessary calculations for all variants including technological and economical evaluation.

Production single parts from sheet metal by the help of technology Hydro-Mec
Toman, Pavel ; Špaček, Jindřich (referee) ; Žák, Ladislav (advisor)
This thesis submits a proposal production technology of single parts from sheet steel No. 11 305, thickness of 2 mm, made from a semi-finished product with a diameter of 246 mm, production run of 50 000 pieces per year. To manufacture the component a technology of hydromechanical drawing is proposed. On the basis of a literary study and calculations a drawing tool was designed, fixed in hydraulic press LPS 4000. To prepare a semi-finished product, flange trimming, and hole punching, a sheet metal cutting is used.
