The manufacturing of level indicator by fineblanking process
Polák, Pavel ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
The project elaborated in frame of engineering studies branch 2307. The project is submitting design of technology production of the extract - section from the deep drawing sheet iron 11 373.1. Pursuant to of the literary pursuit a problem of the deep drawing and calculation was designed drawing in instrument with holder. 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 LEN 63 C (producer APJ Praha), with nominal tensile force 630 kN. Drawing punch and drawing die are produced from alloyed instrumental steel 19 436.9 (POLDI 2002), heat-worked according to drawing documentation.

The deformation necks and their use in forming technology
Grufík, Lubomír ; Štroner, Marek (referee) ; Peterková, Eva (advisor)
The project which was elaborated in bachelor education presents summary of deformation necks and their use in forming technology. Pursuant to of the literary pursuit a problem of deformation necks in forming technology there were formulated description of given methods, summary of methods spreading of deformation necks on the surface of half-finished products, their assets and use in practice. Then there are conspectus of computer simulation, which is used so to evaluation of deformation and transformation, its advantages and disadvantages in practice.

Modern methods of tube- and profiles bending
Zouhar, Ondřej ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
The project elaborated in the framework of Bachelor's study presents a survey of modern methods in the field of bending tubes and profiles. On the basis of literary evidence relating to the bending of tubes and profiles the list was created to summarize all the currently used modern technology in this field. The work covers the theoretical part of the time horizont of the oldest methods of bending to the present methods. In the theoretical part are given the most modern machines used to bend tubes and profiles.

Expanding of tube ends
Riesner, Jan ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
The project is elaborated within frame of bachelor´s studies of branch B2341-3. The project is submitting a summary of methods used for expanding of tube ends. In the first part on the basis of the studies of this problem there was created a set of methods which are used for expanding of tube ends. These methods are divided into three elementary parts according to the technology of production. Next part of this project describes modern methods in use. It is namely expanding of tube ends by radial jaws and method of expanded and towards the end renarrowing figures on the tube ends. In conclusion of this thesis there is treatise on quality checking of expanded tube ends and leakage test.

Sheet metal part manufacturing by drawing
Moravec, Jiří ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
The project developed in the frame of the bachelor study branch B2307-00 presents a proposal of acreation technology of a flange, which is to be a model of the roof lift. The part is made of steel 11 320. Due to the anticipated serial production of 10 000 pieces per year, a number of production options is considered. On the basis of literary studies of the issue of drawing, it is suggested a drawing by a metal tool with blankholder. Due to calculations of tensile strength and work, press LEN 40 C is suggested. Drawing tool is designed to require the most of standard components and is solved through the form of a normal rack fastened to the eccentric press LTN 40 C. Drawing punch and drawing die are made of tool steels 19 436.3 and heat-processed according to the drawing documentation.
