Production of uncapping tray
Čudová, Monika ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
The project elaborated design of technology production of the extract - tray made of stainless steel 17 240. Based on literary study of deep drawing together with calculations, was designed drawing in instrument with holder. The drawing instrument make use of standardised components and it is solving forms to make up stand fitting to hydraulic press CYS 320, with nominal tensile force 3200 kN. Drawing punch and drawing die are produced from high alloyed steel 19 573 heat-worked according to drawing documentation.

Manufacturing of the Ignition Case
Jelínek, Dan ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
The thesis deals with the design of the production of Ignition case. Component is a hollow cover of one channel ignition device, produced by the PBS Velká Bíteš company. It has a constant wall thickness of 0,5 mm and production rate is 15 000 pieces per year. Technology of deep drawing with solid forming tool was picked out of several considered production variants. DC05 deep drawing steel is the material of choice. Based on technological calculations, number of drawing operations needed and forming force was established. Based on those parameters, hydraulic press ZH 10 produced by the Presshydraulika s.r.o. company was chosen for the task.

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.

Influence of input material on technology and production of deep drawn product
Černá, Monika ; Peterková, Eva (referee) ; Šulák, Ivo (advisor)
This bachelor thesis was elaborated in cooperation with company ITW Pronovia, s.r.o within the scope of the bachelor degree and presents an assessment of the effect of material properties and manufacturing technology of a deep-drawn product. In this work the mechanical and technological tests were carried out on the supplied material HT179. This material is further processed into a cartridge for an airbag deployment. During production many defects occurred, especially after cutting out the holes of deep-drawn product. The company established these defects as material property. Therefore it is necessary to evaluate the characteristics of different material sets.

Production of a rotating vessel
Novák, Václav ; Žák, Ladislav (referee) ; Císařová, Michaela (advisor)
The thesis is concerned with the concept of an rotating vessel, that is a part of cotton candy machine. A drawing is cylindrical shape with circular a hole in the bottom, which is made of austenitic chrome-nickel steel 1.4301 with the thickness 1,5 mm. Due to the production volume 50 000 units per year, the pulling technology without wall thinning was choosen. The process of drawing will be performer in one operation. Due to calculated force, the ZHS 400 hydraulic press with a nominal force of 4 000 kN was chosen.

Manufacturing of the water siphon by sheet metal forming
Toufar, Jan ; Lidmila, Zdeněk (referee) ; Jopek, Miroslav (advisor)
The thesis presents a design for the manufacturing of a foul air trap made of chromium-nickel austenitic stainless steel resistant to corrosion 1.4301. In regards to the rotationally symmetrical shape of the air trap, the most fitting technology for manufacturing was deep drawing without thinning of the side and for the preparation of the blank shearing. The selected method of drawing, results in the necessity to utilize a triple action press, which allows for the optimal connection of all selected technologies into one combined tool. All technological calculations were determined and examined. Based on these calculations, a tool was designed. In this tool, the component is assembled out of a coil in three operations of one stroke. The selected machine for production is the press Dieffenbacher PO 250.

Production of grill lid
Míka, Tomáš ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The thesis is focused on the design of the production of kettle grill lid from steel 11 305 (1.0338) with a constant wall thickness of 1 mm and a series of 10 000 pcs/year. For the selected method of manufacture by conventional drawing, technological calculations were performed. Depending on the diameter of the blank, maximum force and other parameters, the tool and the machine were designed. The tool is a single-operation drawing tool with a blank holder and a rib around the perimeter. These functional parts, together with the drawing punch and drawing die, are made of surface-treated cementitious steel 14 220 (1.7131). The drawing tool is clamped into a CBA 250 hydraulic press with a nominal force of 2 500 kN, where the blank holder is controlled by an additional device at the bottom of the press.

Production of the electric motor cover
Havlíček, Lukáš ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The present thesis solves a design of electric motor cover; specifically it deals with manufacture of cover body. A drawing is of simple flange-free cylindrical shape made of deep-drawn 11 305 steel sheet. With respect to the given shape of the component, material and annual series of 25,000 pieces, the most suitable technology selected was the method of deep drawing without thinning the wall by means of conventional tools. The process of deep drawing will be performed using a single-acting deep drawing tool supplemented with technical documentation. This tool is designated for the hydraulic press ZH 40 with a total drawing force of 400 kN. In the technical-economic part, the price of one product (respecting the indirect costs) was calculated for 42 CZK.
