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.

The Antenna Bracket Manufacturing by a Compound Tool
Lipka, Ondřej ; Lidmila, Zdeněk (referee) ; Peterková, Eva (advisor)
This master’s thesis focuses on the concept of large-lot manufacturing of sheet metal component made from DC01 steel. Based on forethought, the method of compound tool combining shearing and bending was chosen. The theoretical part analyses used technologies in detail. In the next part specific course of manufacture was created and supplied with technological calculations. Based on all needed facts the tool was designed and after that forming machine, LDC 160 crank press, was chosen. At the end the usability of designed concept was confirmed with economical calculations.

Corner fitting manufacturing by compound tool
Loukota, David ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
Project have for purpose propose acceptable technology for manufacturing corner fitting by compound tool. Corner fitting is made from steel sheet 11 321.1 thickness 1,5 mm in production set 600 000 pieces in a year. Was select variant with manufacturing compound tool, which make to part on four steps on automatized manufacturing line. This line includes press about power press 1000 kN, feeding and levelling serving and containing rewinder. In economic results are calculated costs production of a piece, final costs and break-even point which is coming after production 216 049 pieces.

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.

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.

Production of the gutter hook
Šobáň, Jakub ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
This bachelor thesis introduces a gutter hook technology production design made of 5 mm thick 11 321 steel sheet. Progressive die tool shearing and bending was chosen as the best production technology. Technology and structure calculations were done for this method. A three step hole punching bender tool has been designed. HMG 100 press produced by TVARtech company – stroje s.r.o. with a coil feeding line by Coiltech company was chosen for production in accordance with the power requirements.

Manufacturing of the Wall Bracket
Fridrich, Ladislav ; Jopek, Miroslav (referee) ; Řiháček, Jan (advisor)
The bachelor's thesis deals with a suitable design of production technology for a wall bracket, which will serve as a speaker positioning system. The part is made of non-alloy structural steel S 235JR with a thickness of 3 mm. The production series is set at 200,000 pieces per year. After evaluating the production possibilities, the technology of bending and progressive cutting is chosen, which are combined in a combined tool. Subsequently, the most suitable arrangement of the part on the sheet metal strip is selected and the sheet metal coil is selected as a semi-finished product for production. Furthermore, technological calculations are performed and drawing documentation of the tool is made. Based on the calculated values, the production machine Mecanica Exacta model CC250 from the company Formetal s.r.o.

Production of mounting pad
Dráždil, Jindřich ; Štroner, Marek (referee) ; Žák, Ladislav (advisor)
The work deals with the solution of the production of a fastening washer, which is intended for the lock of the cable harness. It is made of the 1.4310 material with the thickness of 0.7 mm; the annual production is estimated at 12,000 pieces. The technology of the combined tool in the LEN 24 C machine was chosen as the most suitable method of production, based on the chosen most suitable production technology, calculations and technical and economic evaluation.

Manufacturing of the Mobile Phone Holder
Hřebíček, Robert ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
The master´s thesis is focused on the manufacture of mobile phone holder. The semi-finished productis a 1.5 mm thick steel sheetroll of S235JRG1. The annual seriesis set at 200,000 units per year. For the production of the part, the method of shearing and bending in a combined tool was chosen. Both technologies were dissected in a literary study, and a production process was developed to design a tool. A suitable production line was purchased for the entire production and the suitability of production was economicallye valuated.
