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.

Forming of thin-walled tubes
Baránek, Tomáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This work brings a synopsis of technologies used in the process of thin-walled tubes forming as well as their evaluation. There are various forming methods applied in order to achieve a required shape e.g. tube bending, radial tube tripping and tube forming. The bending is done by several means e.g. collaring, reeling and pressing. In the pipe bending operation the tube may get deformed. Thus there might occur the following bending defects e.g. wall thinning, excessive flattening, wrinkles in the bend, tube suspension. At the radial tube tripping may occur local tube tapering or tube diameter attenuation. Tube forming is dividend into inlet, outlet and flattening.

On the production of special grooves in pipes
Smítal, Tomáš ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
This work was created in cooperation with company Mubea. Introduction part describes purpose of automotive headrest and function of special grooves, which are fitted on headrest frame. Overview of manufacturing technologies of these grooves with short summary of their advantages and disadvantages follows. The main part of this work consists of development of new alternative technology for manufacture special grooves in thin-walled tubes with following experimental verification of technological conditions and shape of grooves. This work also contains evaluation of tool life and wear. Interpretation of the results is performed by calculations and graphically.
