Technology of production parts by forming
Litochlebová, Soňa ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The thesis solves the efficient production of the sheetmetal cover. The new technological procedure will save two manufacturing operations deep drawing. The deep drawing of the cylindrical vessel with a flange and its following calibration in accordance with the design documentation was choosed. The last stage of the deep drawing is the construcion of the circular cut-out and its bending. By doing so the final shape of the cover will be reached.

The manufacture of cylindrical case by forming
Kratochvíl, Tomáš ; Císařová, Michaela (referee) ; Dvořák, Milan (advisor)
Bachelor theses done within bachelor study of specialization in an Engineering technology submits a proposal of production technology of a headless bushing by shaping. A proposed production technology of graded bushing involves an operation of cut-out of semifinished material, draw of an extract with the flange and a curtailment of the flange. The draw is made on the basis of calculation in three operations with the help of holder. According to graphical documentation the extract gets the final shape in the last operation of draw. The purpose of bachelor theses is a design of technological processing and elaboration of drawing documentation of an implement for making the headless bushing.

Production of uncapping tray
Čudová, Monika ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
The project elaborated design of technology production of the extract - tray made of stainless steel 17 240. Based on literary study of deep drawing together with calculations, was designed drawing in instrument with holder. The drawing instrument make use of standardised components and it is solving forms to make up stand fitting to hydraulic press CYS 320, with nominal tensile force 3200 kN. Drawing punch and drawing die are produced from high alloyed steel 19 573 heat-worked according to drawing documentation.

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.

The manufacturing of level indicator by fineblanking process
Polák, Pavel ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
The project elaborated in frame of engineering studies branch 2307. The project is submitting design of technology production of the extract - section from the deep drawing sheet iron 11 373.1. Pursuant to of the literary pursuit a problem of the deep drawing and calculation was designed drawing in instrument with holder. The lower ejector is using for extrusion component. The drawing instrument make use of standardised components and it is solving forms of customary stool close-set on the crank drawing inclinable press LEN 63 C (producer APJ Praha), with nominal tensile force 630 kN. Drawing punch and drawing die are produced from alloyed instrumental steel 19 436.9 (POLDI 2002), heat-worked according to drawing documentation.

Progressive forming die
Bednařík, Josef ; Řiháček, Jan (referee) ; Lidmila, Zdeněk (advisor)
This thesis is focused on the technologi of surface forming. It deals with the problematics of metal cutting, bending and drawing. It describes basic construction principles of utilities and requirements they have to meet in order to function properly. Furthermore, the thesis deals with a basic description of the construction and function of progressive forming tools. In the final part of the thesis, there is a debate about differences in manufacturing a semi-finished product depending whether it is a roll of metal which is handed in automatically, or a sheet of metal which is handed in manually.

Production covering grids of welding machine
Rous, Miroslav ; Štroner, Marek (referee) ; Císařová, Michaela (advisor)
This thesis has been written in the time of my bachelor studies and it describes a production design of a rear cover of a welding set. It focuses on manufacturing of ventilating holes in this component. The cover is made of steel of standard quality 11 320, 1 mm thick. The flattened out shape of the component will be stamped on a Finn Power SG6 machine and subsequently it will be bent on a press brake Safan DNCS 225-4300. The practical part of this thesis contains a design of an instrument making the ventilating holes and an economic assessment.

Manufacturing of parts of microforming technologies
Janoušek, Jiří ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This work deals with point incremental forming technology, which is now booming thanks to the possibility to program the exact path of a simple tool and to implement it on modern CNC machines. It solves the forces in the process, the roughness of the final surface of the products or their accuracy. This technology is divided into one-point and two-point forming and uses better material formability because of little local touch. Thanks to this, it is used in many fields such as medicine or the automotive industry. It is used to produce prototypes and specific components, which would be expensive.

Manufacturing of cover
Březina, Stanislav ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The graduation theses worked up within the frame of the master study programme M21-P, field of study M-STM, sets up a proposal of the technology of the casing manufacture. The casing will be made of steel plate 11 305.21. In terms of a linear study of the questions of deep drawing and the calculation, drawing in the instrument with blankholder was suggested. The upper ejector is instrumental to the extension of the components. The intermediate product will be a roundel created by scission of the sneet panel of 1 mm size. The average of the intermediate product is 124,7 mm, while series 100 000 pieces a year. In terms of the calculations for the operation of drawing, the hydraulic press ZH 30 with specified forming power was selected.
