Design of bending tool for thin-waled copper tubes
Axmanová, Hana ; Peterková, Eva (referee) ; Dvořák, Milan (advisor)
AXMANOVÁ Hana: Design of bending tool for thin-walled copper tubes The project elaborated in frame of bachelor studies branch B-STG is submitting design of the bending tool for the thin-walled copper tubes. There where designed two bending tools with inner bending radius R1 = 13 mm and R2 = 45,2 mm and the bending is implemented by broach into the bending die. There were conducted some bending experiments. The tubes were bended without and with filling by a hand hydraulic press WPP15.

Manufacturing of driving chain gear
Řiháček, Jan ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This thesis deals with the production of driving chain gear, made from sheet metal 14 220.3, with a thickness of 8.0 mm. Set production series is 150 000 pieces per year. After the analysis of possible production methods was choosed fine-blanking technology as productive metod. It was elaborate the proposal of technological solution and constructional design involves selecting of the appropriate blank (sheet metal 8 x 1250 x 2500 mm), design of cutting tool with its documentation and the choice of production machine (triple-action hydraulic press Feintool HFA 3200 plus). In the last part of thesis was done an economical evaluation to assess the efficiency of the production.

Pulley cheek manufacturing
Habr, Stanislav ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This bachelor thesis focuses on the technology of follow cutting. The purpose is to project a progressive press tool for the given component of a pulley cheek made of a stainless steel sheet with the thickness of 1 mm. The optimal variety of component production was set on the basis of the theoretical study in the first part of the project. The progressive press tool uses standardized components and it is realized by using the usual post which is fixed to the compressing machine LEN 63 C (producer TOMA Industries Ltd.). At the end of the thesis, there is an economic assessment of production of the annual batch of 200 000 pcs.

Proposal pressing tool for sheet metal part
Ručka, David ; Peterková, Eva (referee) ; Špaček, Jindřich (advisor)
The in the framework of Bachelor Studies developed project presents a technology- proposal for the production of a pressing tool for the manufacturing of parts from the sheet steel S500MC. On the basis of a literary survey of problems of the component manufacturing through shearing and calculation, cutting in the phase-shearing tool was proposed. According to the shape of the component, a thirteen-steps cutting processes was proposed, two steps of which are free and open to subsequent changes that can occur in the process of shearing. Normalized components from the catalogue company FIBRO were used in the construction of the pressing tool. The press GERB EDELHOFF 80 t was selected as the working device.
