A proposal for improvement of arrangement of machinery and social facilities in the workshop complex
Janouškovec, Petr ; Peterková, Eva (referee) ; Štroner, Marek (advisor)
The diploma thesis deals with technological design. The aim is to improve the layout of machinery on production areas and social facilities on auxiliary areas. The method of storage and material handling is also optimized. The thesis consists of a literature research, which explains selected concepts and basic procedures of technological design. The evaluation of the current state will present the workshop complex, its shortcomings and objects intended for improvement. The results of the capacity calculation made for the selected production representative are used as a basis for new designs. The new concepts of production workshops are focused on improving the production process in terms of the way machines are arranged, material handling and work safety. But also to improve the social and administrative background by optimizing day rooms, changing rooms and washrooms. The cost estimate for specific proposals and the selection of the most suitable variant form the final part.

Design of manufacturing technology for trackpoint part
Garguláková, Lucie ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
The disertation is focused to the technology of fineblanking. It is concerned to a production of part, which will be used as a mechanism for changing the position of seats in cars. The expected production series is 800.000 pieces per year. With reference to the quantity and demanded quality and also accuracy of blank is choosed precisely technology of fineblanking process with pressure edge. The part will be produced on triple-action press produced by Feintool AG Lyss. It is press GKP – F 160 with mechanical-hydraulic drive. This press and specialy create blanking tool produces two blanks per one action.

Manufacturing of chain wheel for motorcycle
Šarocký, Robert ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The aim of this thesis was to propose a suitable technology for the construction process of a chain wheel, which is one of the parts of the drivetrain of a motorcycle. The production series was 200 000 pieces per year. An analysis of several different construction processes was carried out and the process chosen as the most suitable was exact cutting with compression edge. The material of the product was a metal plate (8 x 1000 x 2000) mm 14 220.3, with the width 8 mm.Furthermore, a proposal of a cutting tool was conducted with drawn documentation. Based on the calculation of the required powers the manufacturing machine was chosen, more particularly the three way hydraulic press Feintool HFA 8800 plus. In the final phase, an assessment focused on the effectiveness of the production process was carried out with focus on both the technical and the economic standpoint.

Manufacturing of tubes by forming
Szczygiel, Pavel ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This thesis deals with the basic methods of manufacture of tubes, especially focuses on the technology of seamless tubes. Assess the appropriateness and inappropriateness of individual production methods used and presents technology and types of lines used in practice. It describes in detail process of production seam pipes with a diameter of 116 mm and a length of 97 m in the plant ArcelorMittal Tubular Products Karviná a.s. Also describes in detail each operation in the working section of the strip preparation, welding and is reduced.

Forming of thin-walled tubes
Baránek, Tomáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This work brings a synopsis of technologies used in the process of thin-walled tubes forming as well as their evaluation. There are various forming methods applied in order to achieve a required shape e.g. tube bending, radial tube tripping and tube forming. The bending is done by several means e.g. collaring, reeling and pressing. In the pipe bending operation the tube may get deformed. Thus there might occur the following bending defects e.g. wall thinning, excessive flattening, wrinkles in the bend, tube suspension. At the radial tube tripping may occur local tube tapering or tube diameter attenuation. Tube forming is dividend into inlet, outlet and flattening.

Production of subcomponent for the chassis ball joint
Liškář, Ladislav ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The thesis deals with the design of a technological process for the production a rotationally symmetrical component, which is part of the body for the chassis ball joint of a passenger car. Thesis was developed on request and in cooperation with THK RHYTHM Automotive Czech a.s. On the basis of a literary study, a technological process consisting of 10 operations was designed and elaborated. For the prototype production of the component, a four-column hydraulic press SHPFS 250, with a nominal force 2500 kN, was selected and price offer were prepared. For each of ten operations a prototype tool was designed and prepared assembly drawings. To reduce costs, a single die set was designed to allow all tools to be clamped. The total cost of acquisition of the prototype hydraulic press and tools was set at CZK 2,672,950.

Manufacturing of sensor cover by fineblanking technology
Kosíř, Tomáš ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
Master´s thesis project elaborated within the scope of Master´s degree submits a proposal of manufacturing of sensor cover by fineblanking technology. Sensor cover is manufactured from 4 mm roll of sheet metal. The material component is microalloyed steel S355MC. Annual production batch is 800 000 pieces. Based on the literature study, several possible methods of production parts are described. After evaluation of the required accuracy, surface quality and annual production, the technology of fineblanking using V-ring has been chosen. On the basis of technological and control calculations was chosen the triple action hydraulic press HFA 4500 plus, made by Feintool with a rated power 4500 kN. Design of cutting tool has been designed with moving punch.

Manufacturing of the engine oil tank cap
Polášek, Lukáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The project introduces a technology design of an oil tank cap manufacturing for a turboschaft engine TV3 – 117MT of the MI – 17 helicopter. The component will be produced of DC04 material in a batch of 10 pieces per year. Based on the evaluation of possible production methods the rubber pad forming process with an uncertain instrument (Guerin Method) was chosen. A raw material of 112 mm diameter will be cut out from a metal sheet which dimension will be 1000 mm x 2000 mm x 1 mm. An versatile (universal) tool which is suitable for forming, cutting and bending is designed for a hydraulic press machine CTH 1000. It`s power is 10 000 kN and it is available in the Arial toolshop.

Geometry Optimization of the Stamped Part
Faltýnek, František ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The project presents a solution of geometrical influence on the thinning of the stamped part with thickness 0.3 mm. It can be made from stainless steel X2CrCuTi18, X5CrNi18-10 or X5CrNi18-10 with additional heat treatment. Based on the literature review the technology of drawing was described and a theoretical analysis of shallow drawing was carried out. Material models for numerical simulation and parametric model of punch and die were created. The analysis of thinning dependence on the geometry of the dimple was performed using FEM analysis in ANSYS software. The smallest thinning of value 9.2% was found for X5CrNi18-10 steel with additional annealing and for the upper limit of the dimple radius values, which was set to 1 mm.
