Manufacturing of metal yoke of electrical socket by compound tool
Svozilová, Lucie ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
The project elaborated design of technology production of the metal yoke of electrical socket made of steel DX51D + Z200 by compound progressive tool. Stock material for series of 200 000 pieces is a strip of coil. Manufacturing is realised in five steps consist of cutting, bending and flanging. For flanging was constructed a special mechanism for whose is necessary to use hydraulic counterholder, which is sold as a special peripheral equipment of manufacturing machine. The machine choice was adapted to this criterium. The servopress DSF-N1-800A was chosen as a manufacturing machine, which is made by AIDA company. The press can produce force of 800 kN and make work of 4000 J. Selling price of a one yoke is 24,5 Kč when the profit is one hundred percent. The break-even point comes with 58 140 made piece.

Technology project for production of part "No.2432-cover"
Bednář, Martin ; Šlais, Miroslav (referee) ; Rumíšek, Pavel (advisor)
The project developed in the framework of Bachelor's study presents a proposal of producing technology of cover "2432", part of the sheet. Based on literature research, the studies and on own experience has been produced this work. The issue of materials, cutting, piping, drawing, design of the tool, evaluation of economic and technological design production has been studied. On the basis of the combined instrument has been designed, constructed according to standards, and the use of existing machinery. To resolve it was accounted economic assessment, which enabled decision-making between the semi-finished products for production. It was found that current production is not economically advantageous, compared to the options proposed. It has been ensured and the complex layout of machines in the area of existing production.

Design of production technology of shaped cover
Doležal, Václav ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
This thesis presents a design technology of forming a shaped lid focused on cutting, bending, drawing, as well as trimming and making the required holes. There is described several basic variants of sheet metal forming based on the literature. Production of holes of specified cover, for an annual production of 100 pieces of shaped lid, is solved by unconventional technologies. From subsequent economic evaluation of selected technologies is chosen an appropriate technology to minimize production costs.

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.

Proposal of production technology of uni-axial rod
Zejda, Václav ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The thesis is focused on the proposal of production of a stamped part of the uni-axial rod located in the axle of the truck. The uni-axial rod is made of materiál S420MC with thicknes of 4 mm and the planned series production is 84 000 pieces per year for 7 years. The most difficult point for production is a collar, which create support of the bushing. It is not posibble to produce a required height with conventional one-stage process, which was experimentally verified. In the programm PAM-STAMP there was designed multiple-stage process of the production with the use of numerical simulation. The progressive die was designed for this process of the production. Maximal load of a forming press is 5 057 kN. Production will be located on the forming press Kaiser 8000-50-F5-RKM by ANDRITZ Metals. Maximum force of the forming press is 8 000 kN.

Production of cover plate
Rubáš, Petr ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The thesis is focused on the proposal design of the technology of the production of the cover plate of the lock, which together with other parts forms part of the fifth door of the passenger car. The cover is made of 2 mm metal sheet and includes a number of bends, embosses, cuts and trimmed holes. Based on production requirements and a series size of 1,200,000 pieces over 3 years, the production using a progressive composite tool was chosen. The part will be made in eleven steps composing of cutting, stamping, bending and edging. Micro-alloyed structural steel S355MC was chosen as the most suitable material. The part will be produced on the press KSTU 5000-30-7G RKM from the company ANDRITZ Metals and the price of the product is 14,33 CZK.

Manufacturing of iron holder
Tichoň, Ondřej ; Žák, Ladislav (referee) ; Podaný, Kamil (advisor)
The project deals with design of manufacturing technology of the holder, which is used as a space for the iron to be placed. It is a component made of steel with a quality of 11 373.0 on the form of sheet metal with a thickness of 1,5 mm. Based on the studies of literature relevant to the topic of technologies of cutting, bending and hemming, a production process was developed. After performing technological, constructional and control calculations, a gradual cutter, bending and hemming tools were designed, for which further technical documentation was developed. Each tool consists inter alia of standardized components containing functional parts clamped in guides standing on eccentric presses. For progressive cutting, an eccentric press with designation S 250 was chosen due to meeting requirements for the size of the forming force and the dimensions of the tools, and the press with designation S 160 was used for further operations, which are bending and hemming.

Production Possibilities of Press Brakes
Hrazdíra, Michal ; Jopek, Miroslav (referee) ; Řiháček, Jan (advisor)
The bachelor thesis deals with the production possibilities of press brakes. This is a literary research, in which the aim of the work is to describe the principle of bending. It also focuses on common and special tools and their use in engineering practice. The first part of the work is focused on general bending technology, which discusses the basic principles and possibilities of this method. The main chapter is the bending itself, where the individual types of machines, their components, tools and clamping systems are introduced and described. Furthermore, modern tools and their application in engineering practice are presented. In the last part, the production of the switchboard cabinet is presented on a CNC press brake.
