Forming Technology of Thin Sheets
Musil, Zbyněk ; Žák, Ladislav (referee) ; Dvořák, Milan (advisor)
This bachelor‘s thesis deals with technology of mechanical working of the sheetmetals by cutting for rotary and non-rotary single parts. The first part deal with common dissertation about surface mechanical working, mainly about cutting and meaning of cutting gap in accordance with final cutting. The second part deals with transfer of the new pieces of knowledge from foreign technical literature of surface mechanical working. In the last part there is done an aplication on the particular component.

Production of carpentry joints
Kliš, Vojtěch ; Žák, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
The thesis deals with the design of the technology for the production of the galvanized sheet. It is a carpentry joint that serves for joining wooden structures. The work is focused on metal forming, namely cutting technology. Based on the production series of 30,000 pieces/year, the shape and dimensions of the part, the method of shearing was chosen for production. Furthermore, the necessary technological calculations were performed. The tool consists of standardized components that have been selected based on the standards. For production was chosen eccentric press S 160 E from the company Šmeral Brno a.s. The price of one component is CZK 9.

The reinforcement door locking manufacturing by compound tool
Drápala, Miroslav ; Staněk, Vojtěch (referee) ; Peterková, Eva (advisor)
The submitted project was created in the engineering studies of M-STG Machinery technologies and it is focused on problematics of production of reinforcement door locking. Component will be manufactured by cutting and bending technologies and used material is aluminium alloy EN AW-3103. As a manufacturing stock is used roll of sheet. Manufacturing series is 400 000 pieces a year. Literary study was created according to the mentioned technologies. After the control calculation was proccesed, the compound tool was designed. As a working machine was selected accentric press SMERAL LE 250/40, where the compound tool will be clamped.

Manufacturing of sensor cover by fineblanking technology
Kosíř, Tomáš ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
Master´s thesis project elaborated within the scope of Master´s degree submits a proposal of manufacturing of sensor cover by fineblanking technology. Sensor cover is manufactured from 4 mm roll of sheet metal. The material component is microalloyed steel S355MC. Annual production batch is 800 000 pieces. Based on the literature study, several possible methods of production parts are described. After evaluation of the required accuracy, surface quality and annual production, the technology of fineblanking using V-ring has been chosen. On the basis of technological and control calculations was chosen the triple action hydraulic press HFA 4500 plus, made by Feintool with a rated power 4500 kN. Design of cutting tool has been designed with moving punch.

Sheet metal part manufacturing by drawing
Moravec, Jiří ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
The project developed in the frame of the bachelor study branch B2307-00 presents a proposal of acreation technology of a flange, which is to be a model of the roof lift. The part is made of steel 11 320. Due to the anticipated serial production of 10 000 pieces per year, a number of production options is considered. On the basis of literary studies of the issue of drawing, it is suggested a drawing by a metal tool with blankholder. Due to calculations of tensile strength and work, press LEN 40 C is suggested. Drawing tool is designed to require the most of standard components and is solved through the form of a normal rack fastened to the eccentric press LTN 40 C. Drawing punch and drawing die are made of tool steels 19 436.3 and heat-processed according to the drawing documentation.
