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.

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.
