Production of gear wheel
Tesař, Michal ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
The work deals with the design of gear production technology and the required production series is 80,000 pieces per year. After evaluating various variants of gear production, the method of fine blanking with a vee-shaped was chosen, on which the literature search is also focused. The part will be made of material E 295 with a thickness of 2 mm and the semi-finished product is a coil of sheet metal. Part of the work is also the design of a tool, which is based on technological and control calculations. A three-acting press from the company Šmeral Brno FMB 440 was chosen as the machine. At the end of the work, an economic evaluation was performed.

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 cutter wheel for brush saw
Hanáček, Jakub ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
The project is submitting design of technology production of the part from the sheet iron 12050, thickness of 2 mm and production run of 120 000 pieces per year. From the proposed options of manufacturing was determined that the fineblanking technology by vee ring is the most advantageous. The fineblanking manufacture was designed for fineblanking tool which is set on the hydraulic press HSR - 630 X - TRA from producer SCHMID with nominal force 6300 kN. Functional parts of tool are produced of tool steel 19 437. According to economical calculation it was defined the price of the manufactured part on 61,4 Kč.

The manufacturing of car latch component by fineblanking technology
Augste, Jakub ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
The project elaborated in frame of engineering studies branch Manufacturing Technology (N2307-00) is submitting design of technology production of the latch claw. The latch claw is a component of a car side-door latch assembly and can be used for different car models. The part is made of sheetmetal 4 mm thick. The material for the part is 15CrMo5, alloy steel for case-hardening purposes. Pursuant of the literary pursuit was designed several options of the part manufacture. With regard to required dimensional accuracy, cut-edge quality and expected production run (800 000 pcs. per year) was proposed manufacturing the part by fineblanking technology. Fineblanking is a cost-effective manufacturing method for accurate sheetmetal parts. For manufacturing parts was chosen Feintool hydraulic fineblanking press HFA 3200plus with total force 3200 kN. The press is coupled to a coil reel a strip straighter. Both units of Feintool feeding line FBA 8/300 are very compact, reducing space requirement. For the fineblanking tool design is used a moving-punch system because these tool systems are compact and economical to make and use. The tool make use of standardized cast iron fineblanking die set made by Fibro company. At the conclusion was compared the cost-effectiveness between two production methods – fineblanking with that of laser beam cutting.

Manufacturing of driving chain gear
Řiháček, Jan ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This thesis deals with the production of driving chain gear, made from sheet metal 14 220.3, with a thickness of 8.0 mm. Set production series is 150 000 pieces per year. After the analysis of possible production methods was choosed fine-blanking technology as productive metod. It was elaborate the proposal of technological solution and constructional design involves selecting of the appropriate blank (sheet metal 8 x 1250 x 2500 mm), design of cutting tool with its documentation and the choice of production machine (triple-action hydraulic press Feintool HFA 3200 plus). In the last part of thesis was done an economical evaluation to assess the efficiency of the production.

The manufacturing of metal shim by fineblanking process
Uttendorfská, Magdalena ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
This master´s thesis is concerning the problem of manufacturing technology of the metal shim, which is a part of automobile brake mechanism. Shim will be made of the S460MC steel and the expected production series is 800 000 pieces per year. This quantity, demanded quality and accuracy of blank are the main reasons for application of fineblanking technology process with pressure edge. The blank will be making by triple–action press produced by Feintool, marked HFAplus4500LT. This press produces two blanks per one action.
