Production of trap capture
Barták, Jan ; Heinl, Tomáš (referee) ; Žák, Ladislav (advisor)
This bachelor thesis presents a proposal for the production of trap capture, which is made from construction steel S 235 JRC with a production series size of 6 000 pieces a year in a combined instrument. Based on a literary study and the calculations associated with them, a combined instrument has been designed to combine shearing and bending. The design of the instrument was adapted to produce of a sheet metal roll component. The instrument is placed in a steel stand clamped in an eccentric press LEN 63C by ŠMERAL Trnava. The LEN 63C has a nominal forming force of 630 kN. For corrosion resistance the component is zinc-coated. Part of the thesis is also an economic evaluation of the proposed production technology.

Manufacturing of fitting door
Rosenbergová, Lucie ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This bachelor thesis is focused on the design of the technology of the production of the locks lock plate. The component is made from 11 321 steel in form of scroll with 1,5mm width. Produciton series is 35,000 pcs/year. From the considered procution technologies is cutting and bending in progressive die tool the best. After determining the dimensions of the developed shape was suitable technological proces chosen. Acording to that is desired shape achived in four steps.Based on the performed calculation was combined tool constructed. Component will be manufactured at the eccentric press S 160 E from Šmeral Brno a.s. This press satisfies with dimensions of the tool and also with necessary forming force. The sale price is 20,4 Kč with 70%profit included. Production becomes profitable after exceeding 16 054 pieces.

Manufacturing of a label door fittings
Návrat, Jakub ; Žák, Ladislav (referee) ; Podaný, Kamil (advisor)
Bachelor thesis is focused on the manufacturing of label door fitting. The part is made of a steel 11 320 with a thickness 1 mm. The batch sice is 150,000 pcs/ year. The manufaturing technology was choosen a method of rolling cutting with shallow drawing in the combinated tool. Technology and constructional calculating were made for this technology, from which was designed a tool and for it was made drawing. For the calculating total force and work was choosen a press LEPD 100. The costs for manufacturing one part are 39 Kč. The manufacturing is become cost-effective from 8 071 pieces/year.

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.

Manufacturing technology design of the automotive door hinge
Dvořáková, Jana ; Císařová, Michaela (referee) ; Dvořák, Milan (advisor)
The bachelor thesis presents a production proposal of an automotive door hinge from the sheet metal ČSN 11 321 and an economic evaluation of the chosen variant. The hinge is produced in a combined tool by shearing and bending operations. The tool is clamped to a ZH 2500-2000 NG mechanical press with a nominal force of 2500 kN. Because of the press parameters, alternative solutions are proposed that could lead to an increased capacity utilization. Part of the thesis is a literary research, the output of this research is an overview of cutting technologies with evaluation of their suitability for production of the given part, theory of bending and stamping technologies, a brief outline of the possibility of component production by a method of additive manufacturing and theoretical calculations. Technical variants of series production tools are compared as part of the technical and economic evaluation. Drawing documentation of a component and of a tool are listed in the attachment.

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.
