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 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 horn holder
Kos, Bohumír ; Žák, Ladislav (referee) ; Podaný, Kamil (advisor)
The project elaborated in frame of engineering studies branch 2303T002. The project is submitting design of technology production of the part from the deep drawing sheet iron 11 320.30. Pursuant to of the literary pursuit a problem of the shearing, bending and calculation was designed manufacturing in transfer combined die, which is set on the eccentric press LEXN 100 C (producer TOMA INDUSTRIES s.r.o. Trnava), with nominal force 1000 kN. Functional parts of tool are produced of tool steel 19 436.3.

Technological structures formed parts
Kafuněk, Jan ; Žák, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
The bachelor‘s thesis is composed from research and is described in practical part. Searches contains basic information about the process of cutting, bending and tractioning, which is followed by a description of design principles in the design of sheet metal parts. The practical part is focused on verifying the importance of complying with technological design of products. Products can be divided into the sample products without practical use and products that can already have their use in practise.

Manufactory of drown flanges on a sheet of high-strength steel
Laštovica, Petr ; Vašík, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
Based on study of documents supplied by PWO Unitools a.s. and on advices of design office staff, tool for forming flanges was designed. This tool was then manufactured and it has been used for carrying test of creating flanges of various diameters from high-strength steels. During these tests, the following parameters were optimized – force of upper and lower blank holder and the height of the main guides. Threads were created into these drown flanges. These threaded joins were later tested for maximum torque and maximum compressive strength.

Manufacturing of wall clamp
Hájek, Pavel ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
The project in this bachelor thesis solves a proposal of technology of a wall clamp manufacture. The part will be made of rolled coils (5 mm thick), from steel 11 373 in production of 150 000 pieces a year. Shearing and bending were the most optimal methods chosen from the considered manufacture technologies. The literary study is devoted to the study of chosen technologies. Based on the technological calculations, a transfer combined tool was suggested. According to the size of the overall mould force, an eccentric press LKDR 315 was chosen. This press reaches nominal force of 3150 kN.

Drawing of a tin-coated metal sheet
Hudousek, Jiří ; Císařová, Michaela (referee) ; Lidmila, Zdeněk (advisor)
HUDOUSEK Jiří: Drawing of a tin-coated metal sheet. The project elaborated in frame of master studies is submitting design of the given part production - business card case from tin-coated metal sheet by deep drawing technology. From a variations of the design of the product has been chosen option, when the case is assembled from two identical drawn parts which form the bottom and the lid of the component, the connection of these two parts is arranged by a spacer in form of a plastic insert on which the metal parts are attached. Based on the literary survey and calculations drawing in die with blankholder was designed for metal parts production, according to the force needed and tool size a hydraulic press ZH 100 was selected. Part of the work is the process parameters determination, technical and economic evaluation and drawing documentation.
