The utilization of elastomers in forming technologies
Knebl, Martin ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
The project developed within the bachelor study (branch B2339-00 Mechanical engineering) deals with creation of a review of technologies in the field of forming using elastomers to manufacture desired parts. On the basis of studying literature focused on forming problems the review of these special forming methods and their brief description were developed. Further, the project includes examples of forming machines currently using these methods and appropriate products. The data were obtained from internet sources.

Manufacturing of the turnbuckle of chain
Ondráček, Pavel ; Jopek, Miroslav (referee) ; Peterková, Eva (advisor)
The diploma thesis is focused on the design of the production technology of a chain tensioner. It is a spatial component made of 1.5 mm thick steel sheet with galvanized surface treatment. DC01 steel was selected as the most suitable material. When considering the production technologies, the production in a combined process tool was selected as the most efficient one for the series of 20,000 pieces. Regarding the tool of more complex design including springs, the production will be done in four steps on the LEN 63 eccentric press with accessories used for feeding and unwinding the metal sheet belt from the coil. The final price of the chain tensioner including the bolt and two nuts is 26 CZK.

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.

Production single parts from sheet metal
Hartelová, Karolína ; Matušková, Jarmila (referee) ; Žák, Ladislav (advisor)
The elaborate project present suggestion of technology of produktion pressed piece from engineering steel 11 375 in framework of engineering studies in branch 2307. Production series do 100 000 pieces. By virtue of literary study of surface forming work and calculation was devised procedural tool. The tool is solved by form usual rack fix on crank press LEN 40 (producer TOMA Industries Trnava), with traction 400 kN. Punch and stamping die are made from tool steel 19 436.3 (POLDI 2002) along graphic documentation.

The manufacture of hold-down arm by technology of fine blanking process
Mikyska, Josef ; Žák, Ladislav (referee) ; Peterková, Eva (advisor)
MIKYSKA Josef: The manufacture of hold-down arm by technology of fine blanking process. The diploma thesis deals with innovative technology of „hold-down arm“ by fine blanking technology. The component is made of steel plate no. 12 041.20, 3mm thick. The theoretical part presents possible solutions. In the project there are compared versions of fine blanking technology. Regarding the required size accuracy, surface quality and assumed series production of 600 000 pieces per year the fine blanking technology using V-ring was proposed as the innovative technology. On the basis of technological calculations the triple action hydraulic press GKP-F 100 (produced by Feintool) and a blanking tool were determined. The blanking tool solution is accomplished including calculations and futher documentation. Then, the project implies technical and economical evaluation of the present technology ( conventional blanking with consequentional cutting) and of the newly designed technology. According to the analysis using the newly designed production technology economic and time savings are achieved.

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 Folding meter lock
Václavek, Petr ; Lidmila, Zdeněk (referee) ; Žák, Ladislav (advisor)
The thesis proposes a concept of manufacturing the folding meter lock. The part is made from DC01+LC steel of 0,3 mm thickness. The series size is 100 000 pcs/year. A forming in a progressive combination tool combining shearing, bending and stamping was chosen for the production, based on the analysis of possible solutions. The tool, designed on the basis of literary research of used technologies, produces the part in eleven steps exerting maximal force of 38,5 kN. The production will take place on an eccentric press LEN 40 C. The market price of 3,38 Kč for one piece was established by the technical and economic evaluation.

The manufacturing of feed sheet metal component
Pašalov, Tomáš ; Matušková, Jarmila (referee) ; Peterková, Eva (advisor)
The project made within the bachelor‘s program B2307 represents a proposal of the production technology of a cutting – a device made of steel plate 12020. On the basis of secondary literature dealing with the problematic topic of cutting technology a production of components in sequential device was designed. The sequential device is composed of normalized components and is resolved by using a universal easel. The cutting box is fixed to the compressing machine LEN 40 C (producer TOMA Industries, s.r.o.) with the nominal drawing force of 400 kN. The upper cutting edge and cutting form are made of tool steel class 19, heat-treated according to the drawing documentation.
