The manufacturing of feed sheet metal component
Pašalov, Tomáš ; Matušková, Jarmila (referee) ; Peterková, Eva (advisor)
The project made within the bachelor‘s program B2307 represents a proposal of the production technology of a cutting – a device made of steel plate 12020. On the basis of secondary literature dealing with the problematic topic of cutting technology a production of components in sequential device was designed. The sequential device is composed of normalized components and is resolved by using a universal easel. The cutting box is fixed to the compressing machine LEN 40 C (producer TOMA Industries, s.r.o.) with the nominal drawing force of 400 kN. The upper cutting edge and cutting form are made of tool steel class 19, heat-treated according to the drawing documentation.

Manufacturing of clasp
Polách, Libor ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The project is focused on proposal of clasp technology production. The clasp is a part of central lock in parachute harness. The part is made of galvanized steel sheet metal, sheet metal thickness 3 mm. The part has a spatial shape with holes. Expected manufacture series is 25 000 per year. Bassed on literary studies and manufacture requirements on the clasp, the method of cutting combinated with stamping in combined tool was found the most optimal. The final shape of clasp will be done in three steps. The nobel steel 12 050, which performs required mechanical properties, was chosen as the main material for clasp manufacture. The manufacture will be made by eccentric press LEXN 100C. The expected price of the clasp is 9,7 CZK per piece with counting the procurement price of metallurgical semi-finished product and the tool.

Design of Forming Tool and Machinery for Couting out of Pad
Kolář, Milan ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The Diploma Thesis presents a draft of designated automatic apparatus for cutting out and assembling pads for pressure control valve (DRV2). The theoretical chapter of the Thesis contains selected findings from theory and technology for material cutting. The next chapter contains design solutions for a designated apparatus for cutting and assembling pressure control valves. The pads are etched from 0,08 mm steel plates X2CrNi Mol7-12-2. The shape of the pads is etched on a 35mm-wide belt that is wound up onto a drum. The draft of this new technological facility has been elaborated in accordance with the most suitable technological variant. The cutting tool is made of steel 19 437 that is thermally processed at HRC 62-4. Estimated annual volume of production series is 2 mil. pcs. The cutting and assembly processes are executed with the aid of this designated automatic apparatus.

Manufacturing of the Wall Bracket
Fridrich, Ladislav ; Jopek, Miroslav (referee) ; Řiháček, Jan (advisor)
The bachelor's thesis deals with a suitable design of production technology for a wall bracket, which will serve as a speaker positioning system. The part is made of non-alloy structural steel S 235JR with a thickness of 3 mm. The production series is set at 200,000 pieces per year. After evaluating the production possibilities, the technology of bending and progressive cutting is chosen, which are combined in a combined tool. Subsequently, the most suitable arrangement of the part on the sheet metal strip is selected and the sheet metal coil is selected as a semi-finished product for production. Furthermore, technological calculations are performed and drawing documentation of the tool is made. Based on the calculated values, the production machine Mecanica Exacta model CC250 from the company Formetal s.r.o.

Manufacturing of the Wall Bracket Bicycle
Sikora, Marek ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This master’s thesis presents a proposal for the technology of manufacturing sheet metal part, which is a part of a bicycle wall bracket. The component is made of steel sheet ČSN 11 325 with subsequent surface treatment by galvanizing. Due to the chosen method of manufacturing with a progressive stamping die, the research part is focused on the technology of shearing and bending. Technological calculations were performed for the most suitable production variant, on the basis of which a mechanical press ANDRITZ Metals with the designation KSTU 2000-20-4G-PSE was chosen. Furthermore, the design of the tool itself is presented, which is substantiated by drawing documentation. At the end of the work, a technical and economic evaluation of the produced series of 300 000 workpieces per year is calculated.

Technology of thrust bearing steel cages production
Jež, Marek ; Štroner, Marek (referee) ; Rumíšek, Pavel (advisor)
JEŽ Marek: Technology of thrust bearing steel cages production . Diploma assert of daily magisteral´s studies, study programme – Industry. The branch manufactoring technology, 2 end form, level 2 – summer semester, study group 50 / 51, academical year 2007 / 2008. FSI of Brno University of Technology, department of forming and plastics, May 2008, 78 pages, 54 pictures, 6 supplements. The main theme of the Diploma Theses is the technology of production of tin cages for axial spherical-roller bearings. The given matter includes the production of tin cages for axial spherical-roller bearings – by traction, cutting, punching and calibration. For the chosen representative, i.e. bearing with marking 29 336 M I suggest the substitution of tin cage instead of the brass one. The component (cage) is made of the sheet iron 11 300 of 4 mm thickness, the basic semi product is the sheet panel with the size of 360 x 4 x 3000 mm. In solving the given matter, it is started from the fact that the current state of the cage is still under development. The aim of the Diploma Thesis is to choose the representative, suggest the appropriate technological progress, proposing the engineering design of functional parts of the tool for punching the holes/windows including the necessary calculations and workshop graphical documentation.
