Manufacturing of clasp
Polách, Libor ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The project is focused on proposal of clasp technology production. The clasp is a part of central lock in parachute harness. The part is made of galvanized steel sheet metal, sheet metal thickness 3 mm. The part has a spatial shape with holes. Expected manufacture series is 25 000 per year. Bassed on literary studies and manufacture requirements on the clasp, the method of cutting combinated with stamping in combined tool was found the most optimal. The final shape of clasp will be done in three steps. The nobel steel 12 050, which performs required mechanical properties, was chosen as the main material for clasp manufacture. The manufacture will be made by eccentric press LEXN 100C. The expected price of the clasp is 9,7 CZK per piece with counting the procurement price of metallurgical semi-finished product and the tool.

Manufacturing of pressed metal part
Rubáš, Petr ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The thesis focuses on the design of the technology of manufacture of metallic insert that is included to the shock absorbing element of truck axle silentblock. The insert is made of ´U´ profile metallic sheets with bent edges at both ends, thickness 2 mm. What was chosen as the most fitting technology based on manufacturing requirements and production series size of 160 000 units per year is conventional tool bending. The required form of the insert is achieved by two operations: in the first step, both metallic sheet edges are preliminary bent and in the second step the central part is bent to the ´U´ form. The material chosen for the manufacture of the insert is micro-alloyed structural steel S 315 MC the mechanical properties of which match requirements of the finished product. The part will be manufactured on eccentric press LEXN 100 C and its production cost is CZK 4.60.
