Opravil, Petr ; Kocich, Radim (referee) ; Podaný, Kamil (advisor)
Master’s thesis is focused on the design of the production of a part of the TV bracket. Part is made of steel sheet with thickness of 2,5 mm. The structural steel S 235 JRG1 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 25 000 pieces by year. Part will be made in seven steps and it will require total force of 2 500 kN. Production will be realized on a mechanical eccentric press KSTU 3150-25-F3-P-SE from ANDRITZ Metals with maximum force of 3 150 kN.

Production design of the plug holder
Janoška, Lukáš ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The bachelor thesis is focused on the production of a socket holder for towing devices. The chosen material is mild steel 11 321, which will be subsequently galvanized. The component will be manufactured from 2 mm thick coils of sheet metal in a total production of 100,000 pieces/year. Of the production variants considere, the technology of cutting and bending in a combined tool was chosen. The whole component will be manufactured in four steps with an overall material availability of 89,35 %. A total forming force of 530 kN is required for production. The design of the tool was based on the selected technological process. Mecanica Exacta model DM-S eccentric press from Formetal was chosen as the production machine, which will be subsequently introduced into the automated line.

The production of a gully
Králíček, Václav ; Jopek, Miroslav (referee) ; Peterková, Eva (advisor)
Aim of the thesis is possible innovation in production of a body of floor gully. Material of the gully is an austenitic stainless steel 1.4301 (X5CrNi18-10). This particular gully belongs to floor drainage portfolio of ACO Industries k.s., which is a world leading company in drainage systems. The current welded variant has been replaced by a combination of conventional drawing and dimpling. The geometry of the drain bottom was designed in accordance with the requirements of the ČSN EN ISO 14159 standard and EHEDG documents on the hygiene of equipment for use in the food industry. Technological calculations were made for the new designed geometry, the bottom of the inlet will be made in one drawing operation together with the dimpling of the pre-made hole. The production process was verified using numerical simulation. Part of the solution was the production of a prototype for testing of the flow rate. During the flow rate test, the requirements given by the standard were fulfilled. Combined tool for drawing and dimpling was designed. The tool is designed for use in hydraulic press Dieffenbacher PO250 II with magnetic tool clamping. The financial savings compared to the current floor drain design are about 243,43 CZK. With a specified production series of 700 pieces per year with an expected increase of 15 % in the following years, the return on investment for the purchase of the tool was calculated to be 2,65 years.

Standardization of the copper technological forming process
Březina, Tomáš ; Císařová, Michaela (referee) ; Jopek, Miroslav (advisor)
The thesis focuses on the optimization of bending copper busbars in the Brno branch of the company ABB s.r.o. Busbars serve to conduct electricity and are used in high-voltage switchgears. The semi-finished busbar products are made of electrolytic copper that complies with the EN 13601 standard. Busbars are produced in various shapes and sizes according to the specifications of the switchgear. Part of the thesis involves a tensile test to determine the mechanical properties of electrolytic copper. A practical bending test was performed on a bending machine for bars with different mechanical properties. The entire bending process was simulated in Ansys Workbench software. Using the simulation, the tool stroke was optimized to achieve the desired deviation from the nominal angle. The optimized stroke was subsequently used on the bending machine to achieve the required bending accuracy.

Production of components deep forming
Stloukal, Mojmír ; Benč, Marek (referee) ; Císařová, Michaela (advisor)
The aim of this thesis is to create a research study addressing the issues of deep drawing parts with wide flanges. This work includes the process and technological calculations for drawing rotational parts without flanges and the differences in the technological process for producing parts with wide flanges. Furthermore, the utilization of parts with wide flanges in practical applications is summarized.

Manufacturing of a holder
Bělocký, Jan ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
The thesis focuses on the design of a holder on the central tube under the dashboard of a car. The purpose of the holder is to secure individual dashboard components to the central tube. The required production series is 100,000 pieces per year. The specified material is HC420LA steel with a thickness of 1.5 mm. Various manufacturing methods were analyzed, with the most suitable being a combination of shearing and bending in a compound progressive tool. The selected semi-finished product is a sheet metal strip in coil form. Subsequently, a manufacturing process was designed, and based on it, a tool was constructed in which the part is produced in five steps. According to the calculated forming force of 886 kN, a KSTE 2000 servo press was then chosen.

Production concept of catch basin
Kubátová, Denisa ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
The project is focused on the production of catch basin, used for bottling, and pouring aggressive substances. The basin will be made of corrosion-resistant austenitic chrome-nickel-molybdenum steel 17 346 in a production series of 15,000 pieces per year. The literary research is carried out on the technology of surface forming, specifically drawing. The practical part is devoted to the design of the technology for the production of the part and technological calculations that show that the part will be pulled out in one pulling operation using a holder. Based on the calculations, a pulling tool was designed, and finally, according to the calculated necessary pulling force for the production of the part, a PO 630 press with a nominal force of 6,300 kN was chosen.

Manufacturing of the TV Wall Bracket
Gregor, Radek ; Štroner, Marek (referee) ; Peterková, Eva (advisor)
The master 's thesis deals with the design of a tool for a TV bracket with an expected production of 300,000 pieces per year. After a review of possible production technologies, production in a progressive compound tool that combines shearing and bending was chosen. DC01 material with a thickness of 2 mm in coil was selected for the production of the part with a 52.23% utilization according to the selected cutting plan. Then, a manufacturing process was established for the production of the part, which will be made in six steps. Furthermore, the total forming force of 893,1 kN and the forming work of 1355,8 J were calculated. The mechanical press was equipped with an automatic material feeder ARPL RAL 250 from Attl a spol s.r.o. After the design of the combined progressive tooling, the functional dimensions were determined and control calculations for the critical sections were performed, all of which were met.
