Manufacturing of a VESA holder
Večeřa, Jaromír ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
This diploma thesis presents a proposal for manufacturing of a monitor holder supporting the VESA mounting system. The part is made of DC01 steel with a thickness of 2 mm, while the size of the production series was set at 150,000 pcs/year. After considering possible production variants, the use of a progressive combined tool combining cutting and bending was chosen as a suitable method. After technology control and selecting a suitable production process, calculations of forming forces and work were performed. The total force was set at 699,7 kN and the total forming work reaches 1,2 kJ. The S160 press from the company Šmeral Brno a.s. was chosen as a suitable machine for production. The semi-finished product in the form of a metal sheet coils will be fed into press by feeding device.

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.

Production of sheet metal part
Bachurek, David ; Heinl, Tomáš (referee) ; Žák, Ladislav (advisor)
The project elaborates the desing of establishing angle. It is made from 1 mm thick galvanized sheet EN10346-DX53D+Z100-M-B-C in production 200 000 parts per year. A technology of shearing and bending at progressive die tool was selected from several options as the most suitable technology of manufacturing. There are standartized parts in progressive stamping tool. Tool is designed for eccentric press LEN 63C from producer ŠMERAL Trnava. The eccentric press includes 630 kN of forming force. The function parts are made from alloy tool steel 19 436.9 with heat treatment according to technical documentation.

Production of a part of the data projector bracket
Starý, Petr ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The diploma thesis presents technology production design of a data projector bracket made of 2 mm thickness 11 321 steel plate. Considering the large production quantity and maximum tolerable deviations, a progressive die tool along with cutting and bending was chosen as the optimal solution for this type of production, based on a variant solution. Technological aspects were assessed, the production process was established, and technological and control calculations were performed. According to the total forming force of 2 000 kN, the LDC 250 mechanical press with a nominal force of 2 500 kN, manufactured in Šmeral Brno a.s., was chosen to meet the production requirements. The chosen material in a form of metal sheet coils will be supplied to the machine by a feeding device. The article will be manufactured in six steps. Based on technical-economic evaluation, the final price of a single piece in a series of 250 000 pieces per year was set at 30,80 Kč.

Manufacturing of a mounting clip by compound tool
Krčma, Erik ; Lidmila, Zdeněk (referee) ; Peterková, Eva (advisor)
The master's thesis deals with the design of the production technology for mounting clip for wooden panels. The material is hot-dip galvanized steel DX51D+Z140 with a thickness of 0,5 mm. The annual series of 600 000 pieces will be made from a coil. The proposed production process consists of five steps, which involves puncing, bending and embossing. A progressive die was designed for the production of the given part. The forming force required for stamping is 190 kN. A PE30H mechanical press from Vaptech company was chosen for the fabrication.

Manufacturing of an End Stop for a Sliding Gate
Holusek, Maxmilián ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This masters´s thesis deals with a manufacturing of an end stop for a sliding gate. The semifinished product material is a DC01 steel with a thickness of 3 mm and the production size of the series was set at 100 000 pieces a year. From many posibilities of production alterntives, a progressive die tool was chosen. It combines the two main technologies, which in this case are cutting and bending. After a proposal for manufacturing was made, much needed calculations of forming forces and work were done. The total forming force equals 1 937,7 kN. The next step was making a design of a progressive die, plus picking a S 250 press from a company called Šmeral Brno a.s. A production line from a company called Attl a spol. s.r.o. for feeding a steel coils into the press was chosen.

Manufacture of furniture console
Andrle, David ; Kocich, Radim (referee) ; Žák, Ladislav (advisor)
The work focuses on designing a technology for the production of a furniture console. A sheet metal component made of steel 11 321 with a thickness of 1 mm was proposed, and it is manufactured in an annual series of 10,000 pieces. A literary study was conducted to develop the manufacturing technology for this component, which combines cutting and bending in a combined progressive tool. Technological calculations were performed to design the appropriate tool, and a suitable machine was selected based on the total forming force. As a forming machine, the eccentric press LEXN 100 C was chosen.

Production concept of wall mounting bracket
Tesař, Michal ; Štroner, Marek (referee) ; Císařová, Michaela (advisor)
The thesis deals with the solution of the design of the production of a holder for compact switchgear cabinets. The production series was set at 400,000 pcs/year. The part will be made from DC01 steel with a thickness of 2 mm. The equivalent is steel 11 321. Of the possible production variants, the technology of the progressive forming tool was chosen. The arrangement of the blank on the sheet metal strip is a two-row layout, where two components will be produced at once. A coil of sheet metal with exact dimensions was chosen as the semifinished product. The material utilization coefficient is 80.18 %. The part is manufactured in 8 steps and the necessary technological and structural calculations were made for this variant. The total force to produce the part is 1,240 kN. The machine selected is an eccentric crank press from the company Formetal s.r.o., with the designation CC 160. After the actual production, the components will still be galvanized.
