Optimization of the process of pressing balls into the injector body
Kadlecová, Petra ; Frýza, Josef (referee) ; Brandejs, Jan (advisor)
This thesis is focused on a pressing station as a part of the assembly line in the Bosch Diesel plant in Jihlava. The station provides sealing of a hole in the injector body by ball pressing in. By using several tests the thesis finds out a reason of large amount of waste pieces, checks how can pressing-speed change or lubricant change infuence the pressing process itself and compares capabilities of hydrolic vs. electric pressing machine.
Analysis of state of stress in press and shrink fits
Dudek, Milan ; Řehák, Kamil (referee) ; Horníková, Jana (advisor)
This thesis is focused on calculation of overlap in press fit depending on vield strength. There are used methods of analytic elasticity. The counted values are implemented into the technologic process as updated technologic specification. The practical values of overlap depend on exactness of available technology. The evaluation is done at the end of thesis (economic evaluation as well)
