Production of a part of the TV bracket
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.

Design for the production of a console plate
Andrýsková, Jana ; Kunčická, Lenka (referee) ; Podaný, Kamil (advisor)
The bachelor thesis deals with the design of the production of a new type of cantilever plate, which is used for attaching the staircase structure to the wall made of steel 11 373 with a thickness of 3 mm. It is manufactured by a combination of shearing and bending methods in a progressive compound tool in 4 steps. First the inner holes and part of the shape are cut out, then the outer shape is cut and bent. The production stand is a CC250 eccentric press, where the force required for forming is 903.5 kN and the work is 4,001 J.

Manufacturing of a hanging fitting
Mucha, Jakub ; Benč, Marek (referee) ; Peterková, Eva (advisor)
The paper presents the design of technology for the production of wall-hanging fittings. The optimum production method was selected as the production in a sequential tooling process. The component is manufactured from a 2 mm thick steel sheet. The material chosen is galvanised steel DC01 + ZE. The semi-finished material for production is a strip wound into a coil. The part is manufactured in three steps. The forming force for the production of the part is 797 kN. Subsequently, the Mecânica Exacta CC100 press was chosen.

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.

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.

Manufacturing of kitchen sink
Vágner, Lukáš ; Peterková, Eva (referee) ; Jopek, Miroslav (advisor)
The project deals with the design of production of the kitchen sink made of chromium-nickel austenitic steel 1.4301. Material thickness of the sink is 1 mm. The annual production series is 30,000 pieces. After considering the size of the produced series, a combination of shearing and deep drawing was chosen as the production technology. Shearing of the circular shape was combined with the execution of both draws into one production tool. For this design, the necessary calculations were performed along with verification by simulations in the PAM-STAMP program.The tool is clamped in a hydraulic press PO 400, which has all the necessary parameters. The coil blank is guided through the unwinding and straightening device Compact Line GLK3-1000. The selling price of one sink was set at CZK 1,300. Production becomes profitable after producing 7540 sinks.

Manufacturing of the turnbuckle of chain
Ondráček, Pavel ; Jopek, Miroslav (referee) ; Peterková, Eva (advisor)
The diploma thesis is focused on the design of the production technology of a chain tensioner. It is a spatial component made of 1.5 mm thick steel sheet with galvanized surface treatment. DC01 steel was selected as the most suitable material. When considering the production technologies, the production in a combined process tool was selected as the most efficient one for the series of 20,000 pieces. Regarding the tool of more complex design including springs, the production will be done in four steps on the LEN 63 eccentric press with accessories used for feeding and unwinding the metal sheet belt from the coil. The final price of the chain tensioner including the bolt and two nuts is 26 CZK.

Design of Tool for Louvers Production
Hejna, Jaroslav ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
This thesis presents a tool design for production of embossments into the bottom part of the agricultural silo made of Dx51D material. The research analysis all technologies used for embossing, that is cutting and shallow drawing. This is followed by a chapter on simulation. The tool design itself is described. Its principle is based on tools for punching machines. The upper half of the tool is composed of a weldment to be clamped into pressing machine, into which are mounted functional parts in the form of inserts. The lower tool consists of several bolted plates, punches and a holding plate, which is located on the springs. In order to achieve correct design, necessary calculations were carried out and it was all confirmed by simulation in ANSYS. The two tool halfs are guided by pins attached at the edges of the lower tool. The technical - economical evaluation compares the work of the proposed tool with other possibilities of embossing.

This master’s thesis focuses on the concept of large-lot manufacturing of sheet metal component made from DC01 steel. Based on forethought, the method of compound tool combining shearing and bending was chosen. The theoretical part analyses used technologies in detail. In the next part specific course of manufacture was created and supplied with technological calculations. Based on all needed facts the tool was designed and after that forming machine, LDC 160 crank press, was chosen. At the end the usability of designed concept was confirmed with economical calculations.
