Production of a part of the TV bracket
Vodák, Marek ; Jopek, Miroslav (referee) ; Podaný, Kamil (advisor)
This master’s thesis is focused on the design of the technology to produce a part of the TV bracket. The part is made of steel sheet with a thickness of 2.5 mm. The structural steel S235JR was chosen as the most suitable material with following powder coating. From the possible variants, the production by progressive forming tool was chosen with respect to production requirements and a series size of 30 000 pieces by year. The part will be made in seven steps in designed tool and the total required force is 1013 kN. The production will take place on a mechanical press PCK12 from Bliss-Bret with a maximum force of 1250 kN. The final price of the part is 39.4 Kč.

Production technology of part OPENER
Němeček, Tomáš ; Kopřiva, Miloslav (referee) ; Novotný, Karel (advisor)
The project elaborated in frame of bachelor’s studies branch B-STG is submitting design of technology production of the cutting – a part made of steel plate S235JR (ČSN 11 375). Pursuant to of the literary pursuit a problem of the cutting technology and calculation was designed shearing on the follow cutting tool. The instrument make use of standardized components and it is adapted to attached into the press LEN 40 C (producer TOMA INDUSTRIES), with nominal tensile force 400 kN. Blanking punch and blanking die are made of alloyed instrumental steel 19 436.9 (POLDI 2002), heat-worked according to drawing documentation.

Manufacturing of clamp
Svoboda, Petr ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The bachelor thesis presents the modernization of the technological process of clamp manufacturing in the company FERRUM s.r.o. The part is used to connect the protective elements with the exit ladder. The component is made of 3 mm thick sheet metal. S235JR steel with subsequent hot-dip galvanizing as an anti-corrosion treatment was chosen as the starting material. Regarding to the size of a series of 1300 pieces per week, the shearing and bending technology in the combined tool was chosen from the production possibilities, where the part will be produced in three steps. In the first, holes for the screws are punched and the part is cut from the blank, the second step is free and serves for shift. In the third the part will be bended. A forming force of 618 kN will be required for production, which will take place on an eccentric press LEN 63 C, located in the company's machine park.
