Production of holder
Andris, Tomáš ; Podaný, Kamil (referee) ; Lidmila, Zdeněk (advisor)
The project elaborated the design of technology production of the holder used for fixing pneumatical cylinder at the testing rack. The holder is manufactured from 2 mm thick sheet metal made of structural steel 1.0038 in a production series of 6,000 units/year. After considering the individual production options, shearing in transfer die and simple bending die were selected. Based on the literature study of shearing and bending technology, an optimal production process of the holder was proposed. After technological, structural and verification calculations, the tools were designed, and the technical documentation was prepared. For the production of the holder was selected eccentric press LEXN 100 C made by Šmeral Brno a.s. This press meets the requirements of the forming force, forming work and the dimensions of the tool. According to the calculated economy of production, the production costs of one holder were determined with a 30 % profit to 97 Kč. The turning point when production becomes profitable was calculated to 4 454 units.

Manufacturing of wall clamp
Hájek, Pavel ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
The project in this bachelor thesis solves a proposal of technology of a wall clamp manufacture. The part will be made of rolled coils (5 mm thick), from steel 11 373 in production of 150 000 pieces a year. Shearing and bending were the most optimal methods chosen from the considered manufacture technologies. The literary study is devoted to the study of chosen technologies. Based on the technological calculations, a transfer combined tool was suggested. According to the size of the overall mould force, an eccentric press LKDR 315 was chosen. This press reaches nominal force of 3150 kN.

Manufacturing of car company logo
Prouza, Tomáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The logo component will be produced in a series of 8000 pcs. It will be made from sheet metal 0.5 mm thick stainless steel 17 040. After evaluation of possible modes of production, chosen technology is stamping non rigid tools Guerin. As a medium is used POLYTAN. Literary study is focused on the analysis of this technology. Semi-finished product have circular shape with a diameter of 104.9 mm. Semi-finished product will be produced by use cutting waterjet from steel sheet of size 0.5x1250x2500 mm. Utilization of the steel sheet is 76.58%. The forming components are powered by hydraulic press ŽĎAS corp. Cth400 and a nominal force of 4 MN. This machine is in a manufacturing company available. On the basis of design calculations is chosen comply a tool for Guerin method. When you set a margin 30%, the total profit from the production is 24 096 CZK.

Design for production of lower part of charging station
Skalník, Petr ; Zavadil, Radek (referee) ; Podaný, Kamil (advisor)
This master’s thesis deals with a proposal of production technology of bottom part of charging station which is manufactured by DEL a.s. The component will be made of austenitic steel 17 349 which is 2 mm thick and its production series is 100 pieces a year. Punching and bending by MAG and TIG methods were chosen as the most suitable methods from the considered manufactoring technologies. Stud bolts will be welded by capacitor discharge. Based on the analysis of the technological calculations and the available machines in the manufacturing company was chosen that production is going to run through a punching press Pullmax 720, hydraulic CNC bending press OptiFlex 130 t 3,1 and welding sources TransPuls Synergic 3200, TransTig 1750 Puls and Nomark 65+. Technical and economical evaluation established cost calculation of semi-finished product material, welding wire, gaseous shield and stud bolts. The price of one piece is 3 117,70 Czech crowns.

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.
