The Machines and Tools for the Fineblanking Technology
Šindelka, Marek ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This work provides a brief overview of the used machines and tools designed for fineblanking. Fineblanking is a technology from the field of the surface forming, suitable especially for mass production, which can be used to make a functional component in a single operation. This work also lists the various methods of precision cutting, and describes the tools, that are the main reason for the quality of the product. Furthermore, in this work are listed some examples from today in practice used machines and their planting into the entire complex of production lines.

The manufacture of seat belt buckle
Oborný, Roman ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
Aim of this Thesis is to assess the existing manufacturing method and to propose and make out an optimum manufacturing method for the part „seat belt buckle“. Components made of the steel plate 14 220.3. With respect to requested accuracy, quality and expected production run of 1 000 000 pcs per year, the Thesis includes the proposal of manufacture of the part by a method of accurate cutting with push-on edge. Is designed the cutting tool and selected the suitable machine type for this technology Feintool HFA 3200 Plus. The work contains necessary calculations, economical evaluation and design documentation of the processual tools for the components production. The last part contains the technical and economic evaluation, from which results that, technically and economically, the new production technology is preferable to the existing technology.

Production of form-parts by cutting
Tomášková, Veronika ; Hušek, Martin (referee) ; Dvořák, Milan (advisor)
The thesis elaborated in a master's degree programme Manufacturing Technology and Management in Industry proposes a technology for cutting form parts. The part is made of steel EN S235JRG1 (ČSN 41 1373) with 3 mm thickness. Based on literature review with a respect to yearly volume of production (100 000 pcs/year) and surface quality has been designed new technology of fineblanking for manufacturing of the part. For the technology of fineblanking have been made technological analysis and the tool has been design regarding to the chosen fineblanking press Feintool X-TRA 320. The conclusion of the thesis deals with technical-economical evaluation of manufacturing process and also has been compared the price of the part using unconventional production technology.

Manufacturing possibilities of motorcycle brake wheel
Rozum, Josef ; Dohnal, Ivo (referee) ; Podaný, Kamil (advisor)
This bachelor thesis presents a variant solution of mass production of motorcycle brake wheel. These are part of rotating component of large diameter and small thickness made up mainly of carbon steel. The thesis presents methods for the production of unconventional machining technologies and methods of molding. As appropriate variants were selected technologies of laser cutting, water jet cutting, plasma cutting, blanking and fineblanking. The individual methods are described and evaluated their suitability for production. For fineblanking method which seems to be optimal is indicated the production process.

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.
