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.

The manufacturing of sheet metal part by blanking technology
Žák, Ondřej ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
ŽÁK Ondřej: The manufacture of sheet metal part by blanking technology The project elaborated in frame of engineering studies branch 2307. The project elaborated in frame of bachelor studies in engineering technology field set up proposal technology of production of feed lame – a section from steel metal plate 11 320. Processual shearing was suggested on the basis of belles-lettres problem of blanking and calculation. Shearing use standardized component and is solved by form of usual rack close set on press LEN 25-C, with nominal ductile by force 250 kN. Blanking puch and blanking are made from 19 class alloyed instrumental steels, heat treated according to graphical documentation.

Design of tool for drawing of wire
Kryštof, Marek ; Lidmila, Zdeněk (referee) ; Císařová, Michaela (advisor)
This thesis submits design of tool for drawing wire. The wire is using like a semi-finished product for production of steel abrasive brush. Based on a literary study and calculations, the drawing tools were designed according to the attached documentation. The starting blank for drawing was chosen stainless steel wire made of 1.4301 steel (ČSN 17 240) with a diameter of 1.2 millimeters. The production procedure is designed for the KOCH KTZ II/17 towing machine. The wire is drawn in seventeen operations.

The suggestion of shaped hollow cup technology
Fabík, Pavel ; Šlais, Miroslav (referee) ; Císařová, Michaela (advisor)
The project developed in the master's degree in M2-P, proposes a technology of hollow metal components DX53D+Z275N+NC with holes sheet metal forming. For batch production 225 000 units per year, on the basis of literary study problems of production of components there is designed a new way of producing components for progressive tools and it is compared with current production of simple tools. A progressive tool has 12 steps and combines them in cutting, drawing and extrusion. The tool is mounted in the hydraulic press KAISER KSTU2500 with a maximum force of 2500 kN. Simulations were performed for the campaign in the PAM-STAMP 2G 2011.

Production of cooling cabinet
Halabrín, Marek ; Peterková, Eva (referee) ; Císařová, Michaela (advisor)
The thesis deals with presenting an assembly proposal of a cooling cabinet. The cooling cabinet is made from an austenitic steel plate of the ČSN 17 240 grade with a thickness of 1.5 millimetres. The assembly proposal is composed according to the design documentation. The number of the assembled pieces is 200. The manufacturing shall be made with the use of bending and punching. These manufacturing techniques form a part of this thesis. Finn power C5 with a nominal force of 300 kN and Trubend 5170 with a nominal force of 1700kN are the machines chosen for the manufacturing process. These are standardized machines made from a quenched steel and a steel of the 42CrMo4 type. A technological-economic evaluation comparing expenses of the manufacturing also forms a part of the thesis as well.

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.

Drawing of a tin-coated metal sheet
Hudousek, Jiří ; Císařová, Michaela (referee) ; Lidmila, Zdeněk (advisor)
HUDOUSEK Jiří: Drawing of a tin-coated metal sheet. The project elaborated in frame of master studies is submitting design of the given part production - business card case from tin-coated metal sheet by deep drawing technology. From a variations of the design of the product has been chosen option, when the case is assembled from two identical drawn parts which form the bottom and the lid of the component, the connection of these two parts is arranged by a spacer in form of a plastic insert on which the metal parts are attached. Based on the literary survey and calculations drawing in die with blankholder was designed for metal parts production, according to the force needed and tool size a hydraulic press ZH 100 was selected. Part of the work is the process parameters determination, technical and economic evaluation and drawing documentation.
