The project drawn up within engineering studies, field N2307-00, presents a design for processing a single part – the part is made of sheet steel number S235JRG1 by shearing and bending. On the basis of literary study was design compound tool which is working in three steps. The tool is fixed in eccentric press LEN 40 C (producer TOMA Industries, s.r.o.) with nominal force 400 kN. Blanking punch and blanking die are made from tool steel 19 436 according the drawing documentation.

MIKYSKA Josef: The manufacture of hold-down arm by technology of fine blanking process. The diploma thesis deals with innovative technology of „hold-down arm“ by fine blanking technology. The component is made of steel plate no. 12 041.20, 3mm thick. The theoretical part presents possible solutions. In the project there are compared versions of fine blanking technology. Regarding the required size accuracy, surface quality and assumed series production of 600 000 pieces per year the fine blanking technology using V-ring was proposed as the innovative technology. On the basis of technological calculations the triple action hydraulic press GKP-F 100 (produced by Feintool) and a blanking tool were determined. The blanking tool solution is accomplished including calculations and futher documentation. Then, the project implies technical and economical evaluation of the present technology ( conventional blanking with consequentional cutting) and of the newly designed technology. According to the analysis using the newly designed production technology economic and time savings are achieved.

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 project elaborated in frame of engineering studies branch 2303T002. The project is submitting design of technology production of the part from the deep drawing sheet iron 11 320.30. Pursuant to of the literary pursuit a problem of the shearing, bending and calculation was designed manufacturing in transfer combined die, which is set on the eccentric press LEXN 100 C (producer TOMA INDUSTRIES s.r.o. Trnava), with nominal force 1000 kN. Functional parts of tool are produced of tool steel 19 436.3.

This diploma thesis deals with digital data processing during the design of a mould of ultralight airplane airframe. The final digital model meets the demands on manufacturability by using CNC machining. The realization, in compliance with the reverse engineering approach, was conceived in four phases, which had to be solved step by step in order to preserve the continuity of the process. The phases correspond to the main chapters of the practical part of the thesis. The first part is focused on 3D digitalization of airplane fuselage by using an optic scanner ATOS and photogrammetric system Tritop. The result of this part is digital data of fuselage geometry in form of polygon grid. Next part deals with software reconstruction of collected data – by optimizing polygon grid in order to provide suitable base for surface modeling. The third part, the most time demanding, handles the creation of airplane fuselage surface model. Geometry has to satisfy requirements for smoothness and tangential or curvative connection of surfaces, including other requirements resulting from model usage. The final part of the thesis documents the procedure of deriving a mould from the aircraft fuselage geometry.

The design which was work out in college plan M2I-K is setting up a production technology for an wall clamp from a steel plate 11 321.1. Based on the literature search it was chosen optimal technology of cutting and forming. Structural and technological calculations were implemented for these methods and the composite machine tool was projected. The eccentric bending press CDCH 3000P was chosen because of its working power. Working parts of the tool are made from steel 19 436.3. Price of the component is 36 Czech crowns which is result

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.

The project developed as a part of continuing master’s program in the field of M-STG Mechanical engineering technologies introduces a technological proposal of producing a side panel of computer case. Based on the research of published studies on the topic of surface forming and methods of production of shape openings in sheet-metal, we chose the variant of production of parts using punch press and press brake and selected appropriate material – steel with protective zinc and aluminum coating. Based on the research of published studies on the topic of computer cases we processed analyses of shape designs and chose optimal variant, for which we prepared calculations of production costs in comparison with other proposals.

Aim of the project is to design new flange manufacturing technology. The flange is manufactured from stainless sheet 17 040 with 5 mm thickness and annual production batch of 800 000 pieces. Fineblanking process has been proposed as a new production technology. Technological and construction dimensions have been designed for the proposed technology. The fineblanking process is done by automated machine which consist of unwinding and straightening device, mechanical punch press and winding device. The manufactured part is punch pressed by tool which is located in the punch press in one lift. An economic evaluation compares current manufacturing technology with the proposed technology which is more economically convenient.

KVAPIL Jan: Bending and cutting press machine for representativ part The Master´s thesis, which is developer in an undergraduate degrese in M-VSR, provides a brief overview and description of the cutting and bending technology. The thesis is carried out the calculation, which is essential for the design cutting and bending tools. Models and design are created in the software SolidWorks 2012. The Master´s thesis includes a general procedure after the award until after copy the parts on it.
