Production technology of horizontal cable tray for low-voltage switchgear ABB
Attasek, Ondřej ; Schwarzer, Emil (referee) ; Dvořák, Milan (advisor)
In bechelor thesis is the main task of manufacturing the component that is made of galvanized steel sheet of DX51D+Z/+Z material with thickness of 1,5 mm. The component is produced using technology of cutting and multiple bending. The main aim is to suggest technological process of cable tray for installation of low voltage switchgear for the ABB Ltd. company. Yearly production expectation is 2 650 units. Part of the work is also required technological calculations for notching plan, cutting force and force for bending. In thesis is also elaborated technical-economic evaluation with the drawing documentation.

Proposal of manufacturing technology of bracket
Tůma, Vojtěch ; Schwarzer, Emil (referee) ; Dvořák, Milan (advisor)
The object of this bachelor thesis is to propose manufacturing process of the holder by using technologies of metal processing. The design of the holder of the headset for light sport aircraft is assigned. The first part of this thesis describes preparation of the semi-finished product by the material cutting, bending methods and final surfacing of the part. In the second section there are evaluated technological aspects of the part, made calculations for dimension of the developed shape of the part, cutting force and cutting work, the total material consumption, minimal and maximal radius of the bend, spring-back, bending force and bending work. The bending jig was then designed according to those calculations. Based on the price quotation for the jig acquisition was performed the economical evaluation and was set the sale price of one piece of the headset holder. The process of the design is then briefly summarized in the conclusion.

Forming Technology of Thin Sheets with Coating
Procházka, Lukáš ; Schwarzer, Emil (referee) ; Dvořák, Milan (advisor)
The bachelor's thesis deals with forming technology of thin sheets with coating. It is divided in three separate parts. Firstly, technologies used for forming thin sheets with coating like bending, drawing, spinning and shearing are discussed. Secondly, the thesis presents coatings, their types and means of measuring their thickness as well as examination technologies. The last part consists of a set of experiments testing aforementioned facts on testing samples.
