Production of parts for window fittings
Havliš, Lukáš ; Špaček, Jindřich (referee) ; Žák, Ladislav (advisor)
This project submits a proposal for manufacturing technology of casement and frame window hardware base, made of 11343.23 steel 2,5 mm in thickness and with 15000 pieces annual production volume. The components form an integral part of a window hardware arrest mechanism. From potential variants of manufacturing, the technology of stamping and bending, with the use of a combined tool, was chosen. A bibliographic search examining these technologies was made and the machine LE 250 with nominal forming force 2 500kN was selected. The project comprises structural and technological calculations, including the combined tool design. In the economical part of the project, the product prices were quoted and the break-even point was determined. The break-even point is broken as soon as 13 046 pieces are manufactured.

Form shim manufacturing by compound tool
Bartoš, Martin ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
Purpose of this diploma thesis is a design of a compound tool for manufacturing the form shim. The form shim is made by shearing and bending technology from steel sheet 11 343.1. Thickness is 2 mm. On the basis of a literary study and design calculations was designed the compound tool, which will manufacture this component by 4 actions on the automated line containing rewinder, feeding levelling machine and eccentric press with designed compound tool. Economic calculations show that the designed manufacturing is profitable.

Manufacturing of pipe straps
Suchomel, Svatoslav ; Samek, Radko (referee) ; Podaný, Kamil (advisor)
The diploma work contains a solution of the production technology of a sleeve made of metal sheet 11 373.1, the thickness of which is 1,5mm, in the required amount of 36,000pcs a year. Out of all possible options, the production of cutting and bending in a sequential combination tool was chosen. Based on the literary study and performed calculations the tool is designed and chosen eccentric press LEN 40 C. The price of 2,40 CZK for a piece is derived from the economic evaluation. The work contains drawing documentation of chosen parts of the tool and its assembly.

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.

Production of anchor foot
Kovář, František ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The present bachelor thesis deals with a design of anchor foot used for fixing wooden structures to concrete foundation. The anchor foot is manufactured from 4 mm thick sheet steel 11 375 (S235 JR); the batch production is set out for 100,000 pieces per year. From among production possibilities, production on a combination tool was selected as the most optimal production technology. Based on the literature study of cutting and bending technology, an optimal production process of new anchor foot has been designed. For these production technologies, technological and control calculations have been carried out. Using these calculations, the combination tool was designed and project documentation was worked up. With regard to the size of total forming force, the eccentric press LKDR 500 from ŽĎAS Company was selected. In economic terms, the production costs were calculated for one anchor foot and the turning point of 8,232 pieces was found; exceeding this point makes the production profitable.

Manufacturing of lift bracket
Měřičková, Petra ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The bracket is used to attach the movable mechanism of elevator door. The component is made of constructional steel 11 375 with the thickness of 3 mm. The batch size is 30 000 pcs/year. The rolling cutting method, followed by bending in the combinated tool, was chosen as the optimal technology. Technological and constructional calculations were carried out and the tool was consequently designed. The basic drawing documentation for the tool was implemented. LE 400 press with a nominal force 4000 kN was selected from machinery equipment company. Cost of production of one piece were established, the production becomes profitable for a series of more than 19 133 units / year.

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.
