Production of filter cover
Bachurek, David ; Forejt, Milan (referee) ; Podaný, Kamil (advisor)
The project elaborated design of technology production of the filter cover - section from the deep drawing sheet 11 325 (DC04). Based on analysis was chosen combination of technologies shearing and deep drawing for that option was designed manufacturing process. Forming process is realized on hydraulic progressive press from Sweden company AP&T which has got total nominal tensile force 1740 kN and equipped 5 stations with lower holders and upper ejectors. Deep drawn part is transported between stations by feeders which are part of press. Function parts are made from alloyed tool steels 19 436 and 19 573 which are heat-worked according to drawing documentation. In chapter technical and economical evaluation was determined turning point which become after reaching of 142 840 parts.

Design production of sink
Pecha, Oldřich ; Dvořák, Milan (referee) ; Podaný, Kamil (advisor)
Thesis submits concept of the sink fabrication technology where circular sink is made from rustproof austenitic steel 1.4301 (X5CrNi 18-10) using technology of conventional deep drawing without reducing wall’s thickness. Hydraulic press YL32 - 400 with nominal force 400 kN has been chosen as the production machine. Drawing tool with holder was designed to be used for this technology and its drawing documentation had been enclosed in this thesis. Size of the production series was set for 20 000 products annually. Control simulation of the drawing process has proven that designed component can be made and that computations are correct. Economic and technological estimation was performed which resulted in price being set for 555 czech crowns per piece. After manufacturing first 7 447 products the manufacturing process will become economically profitable.

Suitable lubricants for deep drawing of stainless steel
Mück, Jonáš ; Staněk, Vojtěch (referee) ; Lidmila, Zdeněk (advisor)
The intention of this thesis is the experimental evaluation of different lubricants and their suitability for deep drawing of stainless steel 1.4404. The testing method is based on the friction model at the point of drawing edge and retainers. This model corresponds with a structure of testing fixture. The suitability of every single lubricant for this application has been determined by comparison of the output, which is dependance of the strength on the track with the reference results. The testing has been performed on many different samples provided by various manufacturers. The best result was measured with the oil Kalorex AT 650 S, manufactured by AT Oil, which belongs to the group of environmentally harmful lubricants. Based on the results of this experiment we can conclude that chlorine content significantly increases the lubrication capability especially under high pressure. The modification of preparation geometry which presumes the elimination of certain undesirable disturbances accompnaying the experiemnt has been also proposed.

Evaluation of lubricants for forming
Svobodová, Hana ; Podaný, Kamil (referee) ; Lidmila, Zdeněk (advisor)
The aim of this diploma thesis is experimental testing and evaluation of the suitability of lubricants for drawing stainless chromium - nickel austenitic steel X5CrNi18-10 and comparison of the results obtained from the work [51]. The testing was performed by modeling the friction between the traction edge and the retainer, which corresponds to the real production process at ACO Industries. The introductory part of the thesis describes the process of deep drawing, followed by a description of tribology and the effect of friction. The individual types and properties of lubricants are described in more detail. The main part of the work deals with the testing of lubricants. The results are then described and evaluated.

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.

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.
