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.

Manufacturing of bracket
Stračánek, Rostislav ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
Bachelor thesis deals with the manufacture of bracket, which serves as support rack. This component is produced from construction steel 11 320 of width 2 mm. The production lot of 30 000 pieces a year. As a most optimal technology were chosen technology of shearing and technology of bending. On the basis of technological and engineering calculations there was designed a tool for technology of shearing and tool for bending technology. There was created a drawing specification for tools. As a manufacturing machine was selected eccentric press S 250 with a nominal power of 2500 kN. In the economic part of thesis is calculation of one product, which is 41 CZK.
