Production single parts from sheet metal
Nutilová, Marcela ; Peterková, Eva (referee) ; Žák, Ladislav (advisor)
The project drawn up within the framework of engineering studies in discipline Manufacturing technology (2303T002) presents a proposal for processing a single part – the part is made of sheet steel number S420MC – by blanking, bending and stamping. On the basis of a literary exploration of given problems several variants of processing a part was propounded in order to be made in just one tool. The transfer combined die is fixed in crank press WAINGARTEN ARP 80 with 800 kN nominal force. All functional parts are made of heat treated tool steel number 19 573.3 according to drawing documentation. Lower functional parts of tool (blanking die, stamping die and bending tool) are made as divided.

Design of oil pan production
Švejda, Jakub ; Jopek, Miroslav (referee) ; Podaný, Kamil (advisor)
The project elaborated with the technological design of the production of a rectangular oil pan with a vertical bottom, a flange and the logo of the current manufacturer. The material is 1.4301 stainless steel, the wall thickness is 1,5 mm and the production series is 20 000 pieces per year. The semi-finished product is a metal sheet with the size of 1 500 mm by 3 000 mm, from which rectangular profiles with dimensions of 674 mm by 474 mm are obtained with board scissors in the required quantity of 1 667 pieces. Based on the requirements of the pan, a tool design was created, which was conceived in a combined design enabling all technological operations to be performed in a single working stroke. The basic shape is obtained by deep drawing technology without wall thinning in one stroke with a holder. The required parameters of the flange are ensured by blanking and the logo is created by stamping. The tool was designed on the basis of calculations, using the maximum number of standardized components, and its functionality is conditioned by cooperation with a hydraulic press from Dieffenbacher PO 250, which enables the combination of all three technological operations in one stroke due to two lower holders.

Manufacturing of the water siphon by sheet metal forming
Toufar, Jan ; Lidmila, Zdeněk (referee) ; Jopek, Miroslav (advisor)
The thesis presents a design for the manufacturing of a foul air trap made of chromium-nickel austenitic stainless steel resistant to corrosion 1.4301. In regards to the rotationally symmetrical shape of the air trap, the most fitting technology for manufacturing was deep drawing without thinning of the side and for the preparation of the blank shearing. The selected method of drawing, results in the necessity to utilize a triple action press, which allows for the optimal connection of all selected technologies into one combined tool. All technological calculations were determined and examined. Based on these calculations, a tool was designed. In this tool, the component is assembled out of a coil in three operations of one stroke. The selected machine for production is the press Dieffenbacher PO 250.

Types and characteristics of precision cutting methods
Hrtús, Vojtěch ; Císařová, Michaela (referee) ; Štroner, Marek (advisor)
Bachelor thesis deals with methods of precise cutting and their analysis. The methods used for production of small series were discussed only briefly due to their small occurrence in practice. In the case of fine blanking, an extensive search is made regarding the individual parameters influencing the quality of the shearing process. Furthermore, the work also deals with the shortcomings of the method and possible ways to modernize the technology, either in terms of quality of the shearing process or in terms of economy.

Manufacturing of part of door lock by compound tool
Nečas, Petr ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
Academic thesis, drawn up within the framework of engineering studies, presents a proposal optimal production of garage door lock striker. The part is manufactured from steel sheet S275JR of 1.5 mm thickness. By the analysis of its possible methods of production, with regard to the required annual series of 500,000 pieces, was chosen technology of manufacturing the part in the compound tool by blanking and bending processes. For these technologies was designed solution of the compound tool and automatic production line with the eccentric crank press SMERAL S160, where is the compound tool fixed. The measure of financial performance of manufacturing the part is economical assessing. In the current state is investment return in the production of 179,186 pieces of the parts.

Stirrup manufacturing by compound tool
Brodský, Zdeněk ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
The master´s thesis deals with drawing compound tool for production of stirrup. Stirrup is made from steel 17 240 and his thickness is 1,5 mm. The number of production is 400 000 pieces. After completion of constructional calculations was determined eccentric press LEN 40 C and was designed tool. The work is completed by drawing documentation of the compound tool. In the work is performed economic evaluation too. Present technology (blanking, bending) is compare here with new technology- compound tool. Compound tool is profitable, because time and money are saving.

Technology of production reinforcer for car
Spurný, Petr ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The project, which have been created within the framework study of engineering branch N2301-2, submit technology project of presswork – car reinforcement from material H 220 P and concept of multi-tool set design for pressing operations 1, 2 and 3. Technology process was designed in six operations, based on literary study of blanking and drawing technology. Multi-tool set is design in according with transfer press Müller Weingarten 1250T-1, which was chosen on the basis of advantageousness calculation. Project includes technical and economical evaluation of elaborated technology whit two other variants of production.

Sheet metal forming production of automobile frame top
Marák, Daniel ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The project, which have been created within the framework study of engineering branch N2326, submit project technology process of pressing - part from micro-alloyed steel with higher yield point H 240 LA and proposal of tool design for its pressing. Technology process was designed in ten operations, base on literary studying of cold forming technology. Design of progressive die respects type of press machine, which is specified for production this part. Press KRUPP 400t disposes pressing force 4 000kN. Materials, used for design of tool, are in use by tool shops. Punches and punching dies are produced from steels 19 573, heat-treated according drawing documentation. Drawing punches and dies are produced from steel 19 552, hardened on 56+2HRc and coated by TiCN method.
