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.

The manufacture of seat belt buckle
Oborný, Roman ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
Aim of this Thesis is to assess the existing manufacturing method and to propose and make out an optimum manufacturing method for the part „seat belt buckle“. Components made of the steel plate 14 220.3. With respect to requested accuracy, quality and expected production run of 1 000 000 pcs per year, the Thesis includes the proposal of manufacture of the part by a method of accurate cutting with push-on edge. Is designed the cutting tool and selected the suitable machine type for this technology Feintool HFA 3200 Plus. The work contains necessary calculations, economical evaluation and design documentation of the processual tools for the components production. The last part contains the technical and economic evaluation, from which results that, technically and economically, the new production technology is preferable to the existing technology.

Cutting components with higher accuracy to size
Steiner, Jaromír ; Varjan, Matúš (referee) ; Žák, Ladislav (advisor)
The main topic of this thesis is the fineblanking technology with a vee-ring which was chosen as the most suitable solution. The aim is a design and an assessment of technologicity of the selected component, a draft of the structural design of the tool and an economic evalua-tion of the project. The chain wheel has been designed from structural steel 11500; parameters have been evaluated as appropriate. The instrument has been designed as two-station progressive tool for single-row layout of the fineblanked parts with a moving punch; the vee-ring is positioned both to the blanking plate and to the vee-ring plate. The press was chosen on the basis of the calculated shearing force by Feintool Company. At the selected batch 500,000 units, 5.1 CZK per fineblanket part has been calculated.

Manufacturing of cutter wheel for brush saw
Hanáček, Jakub ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
The project is submitting design of technology production of the part from the sheet iron 12050, thickness of 2 mm and production run of 120 000 pieces per year. From the proposed options of manufacturing was determined that the fineblanking technology by vee ring is the most advantageous. The fineblanking manufacture was designed for fineblanking tool which is set on the hydraulic press HSR - 630 X - TRA from producer SCHMID with nominal force 6300 kN. Functional parts of tool are produced of tool steel 19 437. According to economical calculation it was defined the price of the manufactured part on 61,4 Kč.

Pulley cheek manufacturing
Habr, Stanislav ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This bachelor thesis focuses on the technology of follow cutting. The purpose is to project a progressive press tool for the given component of a pulley cheek made of a stainless steel sheet with the thickness of 1 mm. The optimal variety of component production was set on the basis of the theoretical study in the first part of the project. The progressive press tool uses standardized components and it is realized by using the usual post which is fixed to the compressing machine LEN 63 C (producer TOMA Industries Ltd.). At the end of the thesis, there is an economic assessment of production of the annual batch of 200 000 pcs.

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).

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.

The manufacturing of feed sheet metal component
Pašalov, Tomáš ; Matušková, Jarmila (referee) ; Peterková, Eva (advisor)
The project made within the bachelor‘s program B2307 represents a proposal of the production technology of a cutting – a device made of steel plate 12020. On the basis of secondary literature dealing with the problematic topic of cutting technology a production of components in sequential device was designed. The sequential device is composed of normalized components and is resolved by using a universal easel. The cutting box is fixed to the compressing machine LEN 40 C (producer TOMA Industries, s.r.o.) with the nominal drawing force of 400 kN. The upper cutting edge and cutting form are made of tool steel class 19, heat-treated according to the drawing documentation.
