Design for Manufacturing of a Cover
Rusková, Marie ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
The thesis deals with the design of the air conditioning cover, which will be placed on the roof of the bus. The part is made of 17 240 stainless steel, which is suitable for cold forming, due to its outdoor environment. Deep drawing is chosen as optimal after assessing possible production technologies. Furthermore, the most suitable shape of the blank is proposed and the necessary calculations are carried out, which are verified by numerical simulation. The deep drawing will take place in one operation. Hydraulic press CTH 250 is chosen based on the required force 554.5 kN

Production of components deep forming
Stloukal, Mojmír ; Benč, Marek (referee) ; Císařová, Michaela (advisor)
The aim of this thesis is to create a research study addressing the issues of deep drawing parts with wide flanges. This work includes the process and technological calculations for drawing rotational parts without flanges and the differences in the technological process for producing parts with wide flanges. Furthermore, the utilization of parts with wide flanges in practical applications is summarized.

Manufacturing of the box
Bednář, Jaroslav ; Peterková, Eva (referee) ; Císařová, Michaela (advisor)
This thesis concerns the design and production of a rotary-shaped soap box made of chrome-nickel austenitic steel 1.4301 0.5 mm thick, with a production batch of 50,000 boxes per year. Due to the size of the batch, the cutting and drawing technology without wall thinning was chosen for one drawing operation using a single tool. Based on analysis of the possibility of producing the tool and the necessary calculations, a tool was designed for the production of the lid and another tool was designed for the production of the lower part of the box. The corresponding hydraulic presses were then selected. A CUPS 25 DEU press from HŠV Polička with a forming force of 250 kN was selected to produce the lid and a Formetal PPCT-200 press with a forming force of 2000 kN was selected to produce the bottom part of the box. The production process is fully automated with an unwinding, straightening and scrapping line from Šmeral.

Manufacturing of the wheel center cap
Jiřánek, Jakub ; Štroner, Marek (referee) ; Císařová, Michaela (advisor)
The bachelor´s thesis deals with the production of a protective rotary wheel center cap for the hub shaft of a car. It is made of steel 11 320 and the production volume has been set at 120 000 units per year. Among the possible manufacturing technologies, deep drawing was chosen as the most suitable. The diameter of the blank from which the cover is drawn was determined by calculation to be 110 mm. The number of drawing operations was calculated to be one. The total force required for the manufacture of the component was calculated to be 85 kN. According to decisive criteria, a single-acting hydraulic press CUPS 16 DEU from HŠV Polička was chosen, for which a drawing tool was designed. Finally, drawing documentation was created for the cover, assembly of the tool with the die, punch, blank holder and the body of the blank holder.

The Production Technology of cover
Smejkal, Marek ; Hušek, Martin (referee) ; Císařová, Michaela (advisor)
MAREK SMEJKAL: Drawing technology of cover. Bachelor´s thesis of combined studies, study program INDUSTRY. The branch mechanical engineering, level 1, 3rd grade, academic year 2010/2011. FME of Brno University of technology, May 2011, 46 pages, 5 tables. The project written in the frame of studies branch Manufacturing Technology (B2307) is submitting design of technology production of cover. The part is made of sheet metal ČSN 11 320.21 / W.Nr.1.032, 1,5 mm thick. Based on the literature study the problem of deep drawing was drawn for a given part the manufacturing process. Annual production is 200 000 pieces. There are no special mechanical demands for the part.

Manufacturing of sheet parts by drawing technology
Konvičný, Denis ; Císařová, Michaela (referee) ; Štroner, Marek (advisor)
Drawing techniques are extensively used in the engineering practice so that there is minimal waste of material and, therefore, its use is highly economical. They are used in the serial, as well as mass production and the forming machines for these techniques have high output. This thesis is focused on the issues of the production of sheet metal components by the drawing technique. It describes individual types of the drawing techniques and the production of components of rotary shapes focusing on the acquiring of dimensions of a semi-finished product for cylindrical cups.

Optimization of components production on draw press
Rérych, Pavel ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The diploma thesis present technology production of draining outlet. This is a rectangular deep drawn part, where basic shape is formed in two towing operations now. The used material is an austenitic stainless steel 17 240 with thickness 1 mm. According to the entry documentation the production technology was not change – current technology (it means drawing without thinning the wall) is most suitable. Based on technological and control calculations two-operations production was determined, which will take place in the united conventional instrument. The hydraulic press with marking Dieffenbacher PO250, which has a magnetic tool clamping, per stroke will perform here both operations. The payback was calculated for yearlong production 50 000 pieces after 0,8 years. The proposed production will make the current production more efficient including economic benefits.

The manufacturing of electromotor covering
Stejskal, Luboš ; Špaček, Jindřich (referee) ; Podaný, Kamil (advisor)
This project has been presented for the bachalor branch of study, B2307, it shows the proposal of technological and production process for deep drawn parts. They are produced from the steel (11305). Due to the production volume of 100.000 pieces per year, it was proposed to implement the production process. It basis of the literature study which describes the potential pitfalls of deep drawn technology. After control a technological calculations it was decide to choose the stamping machine CTC 250 (manufactured by ŽĎAS, a.s.).The deep drawn tool has been designed in order to use the maximum capabilities of this stamping machine, specially the upper ejector and the lower holding device.

Production of gully
Švejda, Jakub ; Jopek, Miroslav (referee) ; Podaný, Kamil (advisor)
The project elaborated design of technology production of the gully – the rotational extract with flange from the deep drawing corrosion resistant sheet iron 1.4301. Pursuant to of the literary pursuit and calculation was designed drawing without thinning the wall in two operation and that in one instrument with two bottom holders enabling their combination into one stroke. The drawing instrument makes use of as standardised components as construction elements calculated using calculations and consist of three parts. The bottom and upper are magnetically clamped on the hydraulic drawing press Dieffenbacher PO 250, with nominal tensile force 2500 kN. Both drawing punches and drawing dies are produced from alloyed instrumental steel 19 436.9 heat-worked according to drawing documentation.
