Manufacturing of lift bracket
Měřičková, Petra ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The bracket is used to attach the movable mechanism of elevator door. The component is made of constructional steel 11 375 with the thickness of 3 mm. The batch size is 30 000 pcs/year. The rolling cutting method, followed by bending in the combinated tool, was chosen as the optimal technology. Technological and constructional calculations were carried out and the tool was consequently designed. The basic drawing documentation for the tool was implemented. LE 400 press with a nominal force 4000 kN was selected from machinery equipment company. Cost of production of one piece were established, the production becomes profitable for a series of more than 19 133 units / year.

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 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.
