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.

Production of lamp cover
Tóthová, Romana ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
Project dissertate about manufacturing of lamp cover of steel 13 200 in serie 43 000. After comparing all the alternatives how to make the product , was choose a method of convention deep drawing. Product is manufactured in one operation. Design of apparatus using as standardized, so special parts. It is fitted in hydraulic pressing machine CTC 25. Functional parts are made from tool steel 19 191. Costs of production was calculated on 15,21 crowns a piece. From 26 173 manufactured pieces will the production gainful.

Technology project for general production of the "PC-box cover"
Křivý, Drahoš ; Horák, Jaroslav (referee) ; Rumíšek, Pavel (advisor)
The project, which was done within the scope of engineering’s study shows the proposal of new technology and production organization of a part “PC cover” – a piece done by deep drawing technology from steel sheet of material 11 321. The study shows some of production operations such as cutting, bending, drawing and shearing, included production method solving. In the project were solved also necessary technological calculations and constructional drafts of forming tool. The whole work covers a complex solution of problems related to production of PC cover together with technological disposition of workplace which represents effective layout, distribution and designing of workplace and machines, used for production of the part in a workshop

Production single parts from sheet metal with usage technology deep drawing
Jurča, Jan ; Dvořák, Milan (referee) ; Žák, Ladislav (advisor)
JURČA Jan: The manufacturing of sheet metal part by deep draw technology. Thesis of Master´s Studies, the 5th Year of Study, the School-year 2008/2009, The Institute of Manufacturing Technology, Department of Machining, FSI VUT Brno.The thesis deals with the project of manufacturing the part of the car body – the fifth door by deep draw technology. The material is zinc-coated sheet metal HX220YD EN 10292. Mechanical properties and suitability of the material are evaluated by mechanical tests. The structure of the material is evaluated by metalography scratch pattern. The analysis of draw process and manufacturability of the part is made by calculations and AutoForm software. The production line, necessary machinery and construction solution of draw tool for the manufacturing the part are determined. Last section deals with economical evaluation of the production.

Manufacturing of oil filter
Prokop, Karel ; Humlíček, Jaroslav (referee) ; Podaný, Kamil (advisor)
This thesis deals with the proposal of an oil filter body manufacture. The oil filter body is a rotational part made of DC02 deep drawing steel. With respect to the material, geometry and the size of the production, a deep drawing technology which does not consider wall thinning, was chosen. It was decided about necessity of five drawing operations. Suitable presses for a notching line and the very drawing were selected. Next part of the thesis is given to the design of the rolling tool construction. A drawing die for the first operation is described in details, including the controls and drawings. The economic part compares variants with the requirements of monthly production of 50 000, 180 000 and 350 000 pieces respectively. Due to the economic study, the production of 180 000 pieces per month was chosen.

Technology of production cover by forming
Hansen, Petra ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
Master´s thesis project elaborated within the scope of Master´s degree submits a proposal of manufacture technologies for complicated components with the transition of an elliptical shell into a rectangular shape. Material: Aluminium EN: AW-3003, thickness 2 mm. Estimated annual production: 80 000 pieces. Drawing tool with blankholder was designed based on calculations and literature study of deep drawing. The drawing operation is performed by a hydraulic press ZH 50 with a rated power of 500 kN. The drawing tools are made from tool steel 1.2379 (19 573). Proposal of suitable technologies respectively drawing proces was verified by simulation program FormingSuite and PAM-STAMP.
