Production of cover drain
Hollein, Radek ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
Diploma thesis deals with the design of producing the cover drain. The cover serves to catch impurities while draining liquids. The part is made of 1.4301 stainless steel, using 1-mm thick sheet metal. The size of the annual production series is 30,000 units. As an optimal method of production, progressive cutting and shallow drawing were selected in a combined and a one-purpose tool. Technological and design calculations were performed according to which tools were designed. The LENP 100 press was selected considering the total required pressing force. The cost of one piece production was calculated at 18.91 CZK and the production becomes profitable with annual production higher than 19,478 units per year.

Manufacturing of clip
Melezinek, František ; Harant, Martin (referee) ; Podaný, Kamil (advisor)
The thesis deals with technology of clip manufacture, used as connecting segment of clip frame. The molding is made out of 0,3 mm metal sheet and includes a number of bends and shaped cuts. Based on analysis of suitable production metods and size of series of 300 000 pieces per year, progressive combined tool was chosen as the best option. The part will be made in eight steps combining cutting and bending. For semi-finished product was used 53,4 mm wide roll of sheet metal. As material was choosen spring low alloy steel 51CrV4. Based on calculated force 43kN and work 15kJ the part will be produced on universal hydraulic press CUPS 6,3 DEU manufactured by HŠV stroje a.s.

Manufacturing of body latch
Janáček, Adam ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
Thesis evaluaes production of the body latch, which is used for window, window shutter and door locking. It is made from 11 375 steel sheet which is 1 mm thick. Annual production is 50000 pcs. Progresive cutting and drawing in one combined tool and finishing product in single opperation drawing tool was choosen as most effective. Single operation drawing will be operated manually. Tools was designed by series of technological callculations to which was projected presses Šmeral LDC 160 with additional devices. Acording to economic valuation, cost of production of one piece is 16,50 Kč and production becames profitable after production of 27185 pieces.
