Precision forging
Alrawi, Hassan ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The bachelor’s thesis describes the characteristics of precision forging and forgings followed by the prerequisites necessary for the implementation of technology. In the following sections the theoretical and technological basis of individual methods is discussed which includes closed die forging, isothermal forging, and finally rotary forging. Also, their advantages and disadvantages and practical use was considered. For future development it is necessary to implement the automation of the entire production process in order to optimize the process as best as possible. There is also a possibility of a large-scale development of new processes to replace some of the existing methods

Manufacturing of a post anchor base by compound tool
Pokorný, Michal ; Štroner, Marek (referee) ; Peterková, Eva (advisor)
The bachelor thesis deals with the design of a production process of an anchor, which is used to connect wooden beams to a concrete base. Steel sheet 11 375 of a 4 mm thickness was chosen for the production. A combination of cutting and bending technologies will be used to achieve the desired shape of the component. Technological and control calculations were performed for the cutting and bending operations. Based on the calculations, the compound tool was designed and constructed and a drawing documentation of it was created. A semi-finished product in the form of a roll sheet will be used for production. The PMV 300 mechanical press, supplemented by a feeding line, was proposed as a suitable machine for production.

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 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.

Manufacturing of a safety buckle by fineblanking technology
Ryza, Dominik ; Harant, Martin (referee) ; Peterková, Eva (advisor)
The goal of this diploma thesis is to design a manufacturing technology for the safety buckle. The component is made of steel 11 320. The thickness of the used metal sheet is 3 mm. For the production of the part has been chosen the technology of fine blanking process with pressure edge. This type of manufacturing guarantees the demanded high quality of this special O.E.M. It also makes possible to produce volume up to 700 000 pieces per year. The cutting tool is designed to produce three blanks per one production cycle of the machine. The manufacturing will be done on the triple-action press HFA 3200plus with a feeding line FBA 8/300.

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.

Analysis of manufacturing of component by elastoforming technology
Lorenc, Tomáš ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
In this thesis, processed within the master's degree is the analysis and proposals for modification of production stagnation ribs aircraft L-410. The part is made of aluminum alloy D16. More specifically, it is a 0.8 mm thickness sheet, which after the milling of the blank molded in the basic non-rigid tool by Guerin. After analyzing the entire manufacturing process and the determination of the critical points due to a series of tests carried out were evaluated possible variants production innovation. Proposed changes and their optimization can reduce the labor intensity deleting some time being necessary preparatory and finishing operations manual. It also increases the repeatability and streamline current production panels.

Manufacturing of a connecting pin by cold forming
Koumar, František ; Peterková, Eva (referee) ; Jopek, Miroslav (advisor)
The diploma thesis is focused on the optimization of the production of a rotary connecting pin, produced by bulk cold forming with a focus on upsetting and forward and backward extrusion. The resulting pin will be made of 1.4511 steel. From the three proposed variants of production processes, the optimal variant for four forming operations was selected. Extrusion tools are made of tool steel 19 830. A numerical simulation was performed to verify the suitability of the sequence of the selected variant. The size of the production batch is set at 700,000 pieces / year. In the technical and economic evaluation, the calculated production price of 1 piece of part was coMPared between machining and volume forming, at which the production costs amount to CZK 6,64. The return on this method, with an assumed profitability of 10%, was found for 568 182 pieces produced.

Manufacturing of ignition cover pad
Dostál, Martin ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The thesis solves the design of the technology of production of the ignition cover pad made of steel 11 321 with a thickness of 1 mm with zinc surface treatment. It serves as part of the motorcycle engine sealing system. The part is rotating in shape with a diameter of 35 mm and consists of a central extrusion and a hole. The size of the series is 25,000 pieces per year. Production by a progressive compound tool from a coil with dimensions of 1200 x 500 mm is chosen. 3 forming operations with eating between steps are selected, which are implemented by cutting and embossing technologies. The necessary forming work of 476 kJ and the force of 267 kN are determined, according to which the PRESSIX CNV4 eccentric press is chosen. The machine is introduced into the automated Shungdar SJD and SJK production line, which consists of a straightener, unwinder and feeder.
