Manufacturing of the Mobile Phone Holder
Hřebíček, Robert ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
The master´s thesis is focused on the manufacture of mobile phone holder. The semi-finished productis a 1.5 mm thick steel sheetroll of S235JRG1. The annual seriesis set at 200,000 units per year. For the production of the part, the method of shearing and bending in a combined tool was chosen. Both technologies were dissected in a literary study, and a production process was developed to design a tool. A suitable production line was purchased for the entire production and the suitability of production was economicallye valuated.

Stirrup manufacturing by compound tool
Brodský, Zdeněk ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
The master´s thesis deals with drawing compound tool for production of stirrup. Stirrup is made from steel 17 240 and his thickness is 1,5 mm. The number of production is 400 000 pieces. After completion of constructional calculations was determined eccentric press LEN 40 C and was designed tool. The work is completed by drawing documentation of the compound tool. In the work is performed economic evaluation too. Present technology (blanking, bending) is compare here with new technology- compound tool. Compound tool is profitable, because time and money are saving.

Data selection and optimisation of cutting conditions for progressive production technologies of drilling with a step drill
Barák, Vít ; Fiala, Zdeněk (referee) ; Píška, Miroslav (advisor)
The thesis contains theoretical analysis of drilling by twist drill focused on the step drill. The review includes description of the drill geometry, calculation of the basic parameters of drilling, including forces and process optimization. Following is manufacturing process and analysis of the monolithic step drill designed for the required hole parameters. The optimal cutting conditions are necessary to find for the correct function of the tool. The load values of the tool are accurately assessed using a piezoelectric dynamometer, thereby obtaining the overall progress of individual loads. The roughness of the workpiece is evaluated by the optical measuring device.

Design of a combined tool for holes machining of the universal chuck
Kovář, Matouš ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
This master’s thesis focuses on the design of a combined tool for machining holes of a universal chuck. The thesis analyses the component and technologies used for the production of precision holes for pinions in the chuck body. Furthermore, the current production of precision holes is described, including the used machine, tools, cutting conditions and technological process with machine times. In the next part of the thesis, a proposal of more efficient production of precision holes is made accompanied by a design of a combined tool. The design includes its structural treatment, used cutting tool inserts and drill, the method of clamping, used material, the heat treatment, the determination of the cutting conditions and the development of a new technological procedure. The thesis concludes with a technological and economic evaluation, where the existing and the newly proposed technologies for the production of precision holes for pinions in the chuck body are compared.

Production of the Carbon Holder
Kratina, Patrik ; Řiháček, Jan (referee) ; Žák, Ladislav (advisor)
This master´s thesis focuses on the concept of manufacturing of carbon brush holder, made of steel S235JRG (ČSN 11 343), with thickness of 1,5 mm. In order to reduce costs, it was decided to manufacture the holder with progresive stamping tool, which combines cutting, bending and edging operations in order to achieve specific part shape. Based on relevant calculations the mechanical press LEN 63 C was chosen. The production series was set at 50 000 pieces.

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 the cable holder in progressive dies
Němec, Miroslav ; Heinl, Tomáš (referee) ; Žák, Ladislav (advisor)
This bachelor thesis render design production of the cable holder from corrosion resistant steel X5CrNi8-10 in progressive dies. On basis of theoretical knowledge and carried out calculations was designed construction of progressives dies for production from sheet scroll. This tool include cutting, bending and stamping. For production was selected eccentric press LEXN 100 C from company TOMA with rated forming force 1000 kN. In conclusion bachelor thesis is also economic evaluation.

Production hinge saddle motorcycle
Hanych, Libor ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The project elaborates the design of technology production of the hinge used for fixing saddle motorcycle. The hinge is manufactured from 1 mm thick construction sheet steel 1.0038 in production run of 50 000 pcs/year. A technology of shearing and bending at progressive die tool was selected from various options as the most suitable technology of manufacturing. Based on the literature study of shearing and bending technology, an optimal production process of hinge was designed. After technological, structural and control calculations the tool was designed and the technical documentation was elaborated. The eccentric press LKDR 200 made by ŽĎAS company was selected for the production. This press complies in terms of required forming force and the dimensions of the tool. Using the economic evaluation, the production costs for one hinge were calculated in the amount of 18,5 CZK. 35% profit of the company is included in the price. According to the calculated turning point, the production becomes profitable after 24 187 piece being manufactured.
