Analysis of a Forging Process of the Jaw Turnout Lock Hook
 Barták, Jan ; Štroner, Marek (referee) ; Řiháček, Jan (advisor)
The thesis is focused on optimalization of jaw turnout lock hook forging process which is used in rail transport and is forged from steel of 13 240 grade. Production process of the hook, that is being used in Královopolská kovárna s.r.o. company now, leads to fold defect in the inner side of curved part formation. Conditions of the folds formation were defined using the numeric simulation of this process in Simufact Forming software. After that improvements such as change of semi-finished product size, change of geometry of ancestor shape, bending tools and forging die were made according to linear study of this problematics. These volumetric and geometric changes were verified using the simulation in software and relocation defect did not appear.
