Using of elastomers in forming technology
Drda, Ondřej ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The purpose of this graduation thesis is to investigate and summarize the usage of elastomeric forming, which represent a uniqe method of cold forming in which the elastomeric pads overtake the function of the solid part in a forming machine. The most distinctive feature of elastomeric forming is its low price and a wide range of usage. It can be applied also to metal materials with finished surface. However the major disadvantage of this method is the need of an enormous pressing force. The elastomeric pads fall into two main categories – the open and closed ones. The open type is mostly used for metal sheets bending and roll bending, whereas the closed type finds even greater usage in processes like shearing, drawing (Guerin stamping), deep drawing (Marform, Maslenikov technique) and radial expanding. The thesis further describes the elastomers´ technical features, deformation withstandings, forming principles and their general usage.

Analysis of manufacturing of component by elastoforming technology
Lorenc, Tomáš ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
In this thesis, processed within the master's degree is the analysis and proposals for modification of production stagnation ribs aircraft L-410. The part is made of aluminum alloy D16. More specifically, it is a 0.8 mm thickness sheet, which after the milling of the blank molded in the basic non-rigid tool by Guerin. After analyzing the entire manufacturing process and the determination of the critical points due to a series of tests carried out were evaluated possible variants production innovation. Proposed changes and their optimization can reduce the labor intensity deleting some time being necessary preparatory and finishing operations manual. It also increases the repeatability and streamline current production panels.

Manufacturing of car company logo
Prouza, Tomáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The logo component will be produced in a series of 8000 pcs. It will be made from sheet metal 0.5 mm thick stainless steel 17 040. After evaluation of possible modes of production, chosen technology is stamping non rigid tools Guerin. As a medium is used POLYTAN. Literary study is focused on the analysis of this technology. Semi-finished product have circular shape with a diameter of 104.9 mm. Semi-finished product will be produced by use cutting waterjet from steel sheet of size 0.5x1250x2500 mm. Utilization of the steel sheet is 76.58%. The forming components are powered by hydraulic press ŽĎAS corp. Cth400 and a nominal force of 4 MN. This machine is in a manufacturing company available. On the basis of design calculations is chosen comply a tool for Guerin method. When you set a margin 30%, the total profit from the production is 24 096 CZK.

Manufacturing of motor lid using rubber
Brožek, Michal ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
The work, developed in an undergraduate study, proposes technology of the motor lid. The case shall be produced in a series of 300 pieces per year of 1mm sheet steel 17 240. After an evaluation of possible modes of production, the technology of fragile drawing tool, polytan, was chosen. Literary study is focused on the analysis of this technology. The circular shaped semi-product about the diameter of 222.3 mm, will be produced by a water jet cutting of thin plates with dimensions 1x1250x2500 mm. The capacity utilization of the panel is 68,3 %. For the forming component part is a hydraulic press Cth 250 at a nominal power of 2,5 MN, which is available and made by the company ŽĎAS a.s., used. On the basis of design calculations is a drawing tool for method Guerin designed. After the economic evaluation, the product price was set at 115 CZK.

Unconventional methods of forming
Barcuch, Jiří ; Henzl, David (referee) ; Podaný, Kamil (advisor)
Unconventional forming methods are used in the manufacture of prototypes, small series and verification of experiments. Forming technology can be used in forming by an elastic tools and by high-velocity forming. An elastic tool can be used in the form of elastomers or liquid media. High-velocity forming using detonation for shaping large parts made of hard forming materials, the principle of electrohydraulic and electromagnetic forming of metals and their alloys. Description of their principles, advantages and disadvantages when used in practice.

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.
