Manufacturing of a Segment of the Seat Positioning System
Horák, Jan ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The bachelor's thesis is focused on the design of technology for the production of a seat positioning system made of sheet steel ČSN 11 373 with a thickness of 2 mm. Due to the adjustment of the production quantity of 200 000 pieces per year, the required dimensional accuracy and surface quality of the cutting surface is used by the technology of production of fine blanking with a pressure edge. Part of the work is the implementation of technological and construction calculations, including the design of the cutting tool with the necessary drawing documentation. An alternating arrangement of cut-outs for a coiled sheet metal blank (Ds = 1 200 mm, ds = 500 mm) is chosen as most suitable in the work, which means the use of 36 coils for a given annual production. In the final part of the work, a three-acting hydraulic press Feintool HFA 8800plus is chosen for the production of the component, which is incorporated into the automated production line FBA 6/300, including all necessary equipment for handling, unwinding and straightening the cut sheet metal strip.

Production of universal opener by fineblanking technology
Kučera, Radek ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
The aim of the thesis is to design a manufacturing technology of a part of the universal opener with an innovated design. The component is made of stainless steel 17 240 (X5CrNi18-10). The blank is 2 mm thick sheet metal. Within the literary study the comparison of the possible technologies of manufacturing has been carried out. With respect to the batch size (200 000 pieces) and to the required quality of the component the fineblanking technology has been selected. For the manufacturing of the component a triple action hydraulic press HFA 3200plus has been chosen. This press will be coupled in production line with a feeding line FBA 8/300. The main point of the thesis is to design a cutting tool and to create a drawing documentation. Another part of the project is the technical and economical evaluation of the designed manufacturing process.

Fineblanking component and its manufacturing
Lata, Miroslav ; Peterková, Eva (referee) ; Šlais, Miroslav (advisor)
The diploma thesis deals with a propose of a new manufacturing technology of component called „KULISA“ drawing number 4-DP-05-10/01. The beginning of this work is prepared as a literary study about blanking. There are explained some basic concepts necessary to introduce a blanking topic. Other interest of this work is an assessment of actual state of conventional blanking technology which is being currently used for component production. With regard to the deficiencies of the existing method is proposed new technology of fine blanking. In the proposal is evaluated technological site of component construction and blanking tools are proposed with stress analysis included. Last part of the work deals with the economic evaluation, where is being compared efficiency of existing and new technology.

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.

Production form-parts by cutting
Hansen, Petra ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The thesis elaborated in an undergraduate degree in Manufacturing Technology, proposes a technology for cutting form parts. The specified component is made from 3 mm sheet metal. The material component is structural steel EN S235JRG1. Based on the literature study, several possible methods of production parts are described. After evaluation of the required accuracy, surface quality and yearly volume of production (100 000 units / year) the technology of fine blanking has been chosen. For the production of components will be used: Triple hydraulic press, HFA 3200plus, made by Feintool. Cutting tool has been designed with moving punch, and the tool contains standardized parts. The economic comparison has been made between the methods of precision cutting, trimming and unconventional classic laser technology.

Precision blanking of components
Augste, Jakub ; Samek, Radko (referee) ; Žák, Ladislav (advisor)
The project elaborated in frame of bachelor's study programme B2341–3 is submitting literary pursuit of technologies production of the fineblanking components. This thesis is concerned with a problem of the fineblanking in mass production, concretely development, principle, technological direction, tools, presses and cost-effectiveness of fineblanking. The thesis was also compared differences between conventional stamping and fineblanking. Methods suitable for small-lot production are described only marginally.
