TV Wall Bracket Manufacturing by Compound Tool
Pecinová, Hana Elisabetha ; Lidmila, Zdeněk (referee) ; Peterková, Eva (advisor)
The thesis concerns the layout of manufacture technology of the bracket for TV wall mount. Based on a trade-off study of several technologies, a solution using a compound tool was selected as the most appropriate for given application. Non-alloy quality steel 11 321.1 was selected as a material for the bracket, with a synthetic paint applied as a surface finish. Analysis of manufacturing parameters was conducted, based on which the two-stroke crank press LKDR 200 was selected. Capability of that machine is sufficient in terms of press force and working space. Forming tools are made of high alloy tool steel 19 436.4, heat treated by quenching and annealing. An evaluation of economic aspects is included in the thesis.

Manufacturing of ignition cover pad
Dostál, Martin ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The thesis solves the design of the technology of production of the ignition cover pad made of steel 11 321 with a thickness of 1 mm with zinc surface treatment. It serves as part of the motorcycle engine sealing system. The part is rotating in shape with a diameter of 35 mm and consists of a central extrusion and a hole. The size of the series is 25,000 pieces per year. Production by a progressive compound tool from a coil with dimensions of 1200 x 500 mm is chosen. 3 forming operations with eating between steps are selected, which are implemented by cutting and embossing technologies. The necessary forming work of 476 kJ and the force of 267 kN are determined, according to which the PRESSIX CNV4 eccentric press is chosen. The machine is introduced into the automated Shungdar SJD and SJK production line, which consists of a straightener, unwinder and feeder.

Manufacturing of body latch
Braško, Zdenko ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
Bachelor thesis is concerned with the design of production a body latch. Latch is used for engaging the door in a closed position. Component is made of structural steel 11 321 with a thickness 1 mm. The batch size is 35,000 pcs/ year. As the optimal production technology was chosen method of rolling cutting with shallow drawing in the combinated tool. Technological and constructional calculations were maked and tool was designed by it. For this tool has been created drawings. Of the total work force requirements and for the production of components was set press machine LEN 40 C. The cost of production of one piece were determined to 10,57 CZK / pc. Production becomes profitable for a series of more than 25 083 pcs / year.
