20.500.12556/DKUM-76503 Vpliv trdote materiala pločevine na profil reza izdelka in obrabo pestiča v orodju za izsekovanje diplomsko delo The imapact of material hardness of sheet metal on cutting profile of product and punch wear in punching tool Diplomsko delo obravnava, kako se profil reza izsekanega izdelka spreminja z spreminjanjem trdote vhodnega materiala pločevine. Na začetku je na kratko predstavljena teorija izsekovanja, s pomočjo katere bralec lažje razume sam proces izsekovanja. Ker diplomsko delo obravnava tudi obrabo pestiča, sledi nekoliko več besed o pripravi pestiča pred uporabo v orodju, ki zmanjša njegovo obrabo. Informativno pa je prikazana tudi trdnostna simulacija pestiča in matričnega vložka v programskem paketu Solidworks. Na kratko je predstavljeno orodje in ekscentrična stiskalnica s postrojenjem, s katerima se izvaja omenjeni preizkus. V zaključnem delu naloge je opisan celoten potek raziskave ter predstavitev rezultatov z njihovim ovrednotenjem. The thesis deals with how the cut profile of the cut product changes by changing the hardness of the input material of the sheet metal. At the beginning of the work, a well-explained theory of stamping is briefly presented, with the help of which the reader can more easily understand the stamping process itself. Since the thesis also deals with the wear of the punch, there are also a few more words about the preparation of the punch before use in the tool that reduce its wear. As an informative, the strength simulation of the punch and matrix insert in the Solidworks software package will also be shown. The tools and the eccentric press with the plant with which the mentioned test will be performed will also be briefly presented. The final part of the thesis describes the entire course of the research and the presentation of the results with their evaluation.
