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.

Production of wash basin strainer
Pecha, Oldřich ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
Bachelor's thesis focuses on wash basin strainer fabrication technology. This rotary component will be made from ČSN 1.4301 (X5CrNi 18-10) material. Stated annual production is twenty five thousands completed products. Chosen technology for fabrication is drawing with no wall thinning with the use of hydraulic press LEN 25C. Tool for deep drawing will be used for completion. This tool's drawing documentation is enclosed in this thesis. Single-operation tool for deep drawing was designed. This tool contains blank holder, punch, die and gas spring. In the economical section was calculated that total cost of one product is 33 czech crowns. For the production to generate income at least 13 628 products would have to be made.

Producing 100 mm caliber shell
Santa, Patrik ; Harant, Martin (referee) ; Lidmila, Zdeněk (advisor)
The bachelor’s thesis is focused on producing 100 mm caliber shell. It’s a cylindrical component with variable thickness of the wall. Material used is brass CuZn30. After evaluation of different producing options, deep drawing was chosen as the most convenient technology. Semi-finished product is round blank from which, using deep drawing, a cup will be shaped. Subsequently using technology of deep drawing with wall thinning, wall thickness will be reduced to a required dimension. Shearing runs on a hydraulic press FB one 8800 and deep drawing is provided by hydraulic press YW27-1000A. Machines used were selected on the basis of calculated forces. Also a drawing documentation was processed for the last draw and for a mold used for narrowing the orifice.

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.

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.

Technology of production parts by forming
Litochlebová, Soňa ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The thesis solves the efficient production of the sheetmetal cover. The new technological procedure will save two manufacturing operations deep drawing. The deep drawing of the cylindrical vessel with a flange and its following calibration in accordance with the design documentation was choosed. The last stage of the deep drawing is the construcion of the circular cut-out and its bending. By doing so the final shape of the cover will be reached.
