Výroba rohového dřezu / Production of a corner sink

Soldán, Josef January 2019 (has links)
This diploma thesis if focused on the production of a corner sink from stainless steel sheet 1.4301. Based on analysis of manufacturing possibilities the best solution is to produce corner sink by a conventional tool in serval operations, which was the main focus of theoretical part of this thesis. In addition, this choose is in conform with assignment of this diploma thesis. Practical part of this thesis was focused on check of technologicity followed with design of suitable shape of sheet for deep drawing. Further calculation of amount of required draws in specific drawing operations, calculation of drawing forces and works and calculation of parameters of drawing tool. These calculations were checked by numerical simulation which discovered possible defects whereupon the shape of corner sink was modified in order to limit these defects. Based on these calculations the universal drawing tool was designed. In the ending of this thesis the techno-economic evaluation was made which confirmed the economic advantage of this universality.
