Abstract

Cilj diplomskog rada je bio predložiti moguća unaprjeđenja procesa u smislu smanjenja naprezanja tijekom procesa oblikovanja deformiranjem, točnije postupka savijanja. Moguće promjene su analizirane računalnom simulacijom u programu MSC Marc Mentat SE, a proveden je i proračun sila i naprezanja. Prije analize su opisane tehnologije oblikovanja deformiranjem, mehanizmi koji se odvijaju tijekom oblikovanja, kao i prednosti oblikovanja deformiranjem u odnosu na druge. Opisane su tehnologija oblikovanja savijanjem, vrste savijanja, alati za savijanje i momenti kojima je materijal izložen tijekom savijanja. Na kraju rada, u zaključku će su predložena moguća unaprjeđenja.

Abstract (english)

The goal of the thesis was to propose possible process improvments in terms of stress reduction during the forming process by deformation, more precisely the bending process. Possible changes were analyzed by computer simulation in the MSC Marc Mentat SE program, forces and stresses were also calculated. Before the analysis, deformation forming technologies were described, the mechanisms that take place during forming, as well as the advantages of deformation forming compared to others. Bending forming technology, types of bending technology, tools used for bending, and moments to which material is exposed during bending were described. At the end of the work, possible improvements were suggested in the conclusion
