Manufacturing of biscuit pan
Pešava, Josef ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The solved part – the „cookie cutter“ is made of tin material TH 370 0,24 mm thick. It will be used for baking cookies at temperatures up to 250°C. Estimated annual series is 100 000 pieces. The most optimal method from the variant solution of the production of the part was chosen. In the first operation the circular rondel is cut from the sheet and there is the conventional campaign in the second operation. Based on calculations the nearest suitable press LEN 25 C is selected for the production. The price of 2,58 CZK per mold was calculated in, the technical-economic evalution. The pull tool is designed from technological and design calculations.

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.

Influence of surface treatments on the quality of molded parts
Okurka, David ; Dvořák, Milan (referee) ; Hušek, Martin (advisor)
This thesis examines the influence of surface treatments on the quality of molded parts. At the beginning of this work explains why the finish and what are the current demands on the development of manufacturing technologies. It further describes the most common surface treatment of metals, which are currently very often occur. The next section is divided into forming the surface and volume and describes the different types of species-forming, such as cutting, bending, drawing, etc. At the end of the work described cooperation with the Hettich ČR, k.s. and Tokoz, a.s.

The manufacturing of electrical set covering for halide lamp
Bezpalec, Jan ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
BEZPALEC Jan: The manufacturing of elecrical set covering for halide lamp. The project elaborated in frame of Bachelor's studies branch 2307. The project is submitting design of technology production of the extract from the deep drawing sheet iron 11 320.21. Based on literature studies campaign issue, with regard to the series 20 000 pieces, it was suggested drawing a conventional method. Extract is drawn to a single operation using the retainer.Drawing punch and drawing die are produced from alloyed instrumental steel 19 436.9 , heat-worked according to drawing documentation.

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.
