Manufacturing of mirrors clamp
Večeřa, Jaromír ; Jopek, Miroslav (referee) ; Podaný, Kamil (advisor)
This thesis presents a proposal for manufacturing of a mirror clamp, used for wall mounting. The clamp is made of stainless steel 1.4301 with a thickness of 1 mm. Manufacture series produces 40,000 pcs/year. After considering the individual manufacturing options, production in the combined process tool was chosen. The manufacture takes place in five steps, the utilization of the material is 84.1 %. This was completely proved by technological, design and control calculations. According to these calculations, a tool was designed with all of the technical documentation. Due to the forming force of 180 kN and the work of 113 kJ, the eccentric press T-30 CE from the company SanGiacomo Presse was chosen.

Analysis of the Production Processes Influence on Rail Deformations
Skalník, Vít ; Podaný, Kamil (referee) ; Vaněk, Mojmír (advisor)
The aim of this work is to assess the possibilities of using numerical simulation tools in the process of laser welding of the guide rail of a car seat. In the diploma thesis, a description of the components and the problem, which consists in the deformation of the groove of the guide rail, was made. A description was made of the manufacturing operations that the components go through. The positives of selected welding methods were evaluated and the choice of those used in production was justified. A description of the issues of laser welding, deformation and the use of simulation tools was made. The influence of individual production operations was evaluated in terms of the size and nature of deformations. Using the Visual – Mesh, Visual – Weld and Visual – Assembly simulation tools, which are products of the French company ESI Group, the same state of the simulated and real process was achieved. Subsequently, a proposal for the elimination of deformations and its verification using a simulation tool could be approached. The use of a spacer wedge, which acts on the most deformed places of the groove, was proposed. By its application, the resulting deformations were eliminated or significantly reduced. In the last part of the work, a technical and economic evaluation was made, taking into account the current global crisis and the important role of the automotive industry.
Production of supporting plate
Filip, Jiří ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The thesis presents a proposal of technology for production of supporting plate, which is a top part of a service trolley, serving for manipulation with switch of high voltage. The supporting plate is manufactured of low carbon, deep drawing steel DX51D+ZM thickness 2 mm and quality according to EN 10346. Annual serie was set for 200 pieces. In evaluation of production possibilities were chosen technologies of punching and bending. There was designed unfolded shape of the sheet metal with dimensions 1068 x 900 mm and created cutting plan. As was found, from one metal board is possible to cut out 2 pieces of the supporting plate, while 70% of material use. In the next step, punching tools were chosen and manufacturing process was made. The highest achieved cutting force was 122,8 kN. The chosen machine is hydraulic CNC press TruPunch 5000. For bending there was created a bending plan, according to which bends will be made in thirteen steps. Used bending tools are punch OW209/S and two types of matrix EV005 + FWZ and EV006 + FWZ. Maximal achieved bending force is, according to the calculation, 259,8 kN. Bending operations will be made on CNC press TruBend 5130. In a technical and economical evaluation was determined cost for the material, which is 57 337,5 Kč.
Temperature measurement using the pyrometers
Holík, Denis ; Kaňa, Václav (referee) ; Podaný, Kamil (advisor)
The thesis is pursuing research and analysis of information about function principles of pyrometers. Complex problematic of particular types of pyrometers and options of practical use is analysed. Basic errors of contactless temperature measurement are also included. Parameters of particular types of pyrometers are processed in the form of a table.
Manufacturing of clip
Melezinek, František ; Harant, Martin (referee) ; Podaný, Kamil (advisor)
The thesis deals with technology of clip manufacture, used as connecting segment of clip frame. The molding is made out of 0,3 mm metal sheet and includes a number of bends and shaped cuts. Based on analysis of suitable production metods and size of series of 300 000 pieces per year, progressive combined tool was chosen as the best option. The part will be made in eight steps combining cutting and bending. For semi-finished product was used 53,4 mm wide roll of sheet metal. As material was choosen spring low alloy steel 51CrV4. Based on calculated force 43kN and work 15kJ the part will be produced on universal hydraulic press CUPS 6,3 DEU manufactured by HŠV stroje a.s.

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.

Starý, Petr ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The diploma thesis presents technology production design of a data projector bracket made of 2 mm thickness 11 321 steel plate. Considering the large production quantity and maximum tolerable deviations, a progressive die tool along with cutting and bending was chosen as the optimal solution for this type of production, based on a variant solution. Technological aspects were assessed, the production process was established, and technological and control calculations were performed. According to the total forming force of 2 000 kN, the LDC 250 mechanical press with a nominal force of 2 500 kN, manufactured in Šmeral Brno a.s., was chosen to meet the production requirements. The chosen material in a form of metal sheet coils will be supplied to the machine by a feeding device. The article will be manufactured in six steps. Based on technical-economic evaluation, the final price of a single piece in a series of 250 000 pieces per year was set at 30,80 Kč.
