Abstract:
Merska ustreznost izdelkov iz visokotrdnostnih jekel je eden izmed pomembnih kriterijev za sprejem izdelkov pri kupcu. Orodjarne želimo priti do tega cilja s čim manjšimi stroški in v čim krajšem času. V nalogi je prikazan proces, kjer s pomočjo simulacij in metod za modeliranje novih, kompenziranih površin izvedemo to pred prvim preizkusom orodja. Poleg dveh posrednih metod korekcije površin orodja je prikazana tudi direktna metoda, kjer rezultate simulacij neposredno uporabimo za izdelavo kompenziranih površin oblikovnih orodij. Na praktičnem primeru je prikazan sistematičen pristop izvedbe simulacij preoblikovanja, ki so bile potreben pogoj za dobre simulacije elastičnih izravnavanj in posledično modeliranja novih površin orodja. Z modeliranjem dobrih kompenziranih površin za prvi preizkus se orodjarne tako izognemo velikim stroškom, ki lahko nastajajo pri kasnejših korekcijah orodja po preizkušanju. Prikazani kompleksen izdelek se je izdelal v več stopnjah, to pa je zahtevalo izvedbe simulacij elastičnega izravnavanja po vsaki od operacij in tudi sistematični pristop izvedbe kompenzacij površin v vseh oblikovnih operacijah orodja.

Title:
Springback compensation in forming process for high strength steels
Abstract:
Measurement adequacy of the products from high-strength steels is one of the important criteria for customers´ acceptance of the products. Tool workshops want to achieve this objective with minimal costs in the shortest possible time. The thesis presents a process, in which with the help of simulations and methods for modelling new compensated surfaces, we carry out this prior the first tool test. In addition to two indirect methods of the correction of tool´s surfaces, also a direct method is presented, where the simulation results are directly used for production of compensated surfaces of the design tools. A practical example presents a systematic approach for implementation of modification simulations, which were a necessary condition for good simulations of springbacks and consequently modelling new tool surfaces. By modelling good compensated surfaces for the first test, the tool repair workshops therefore avoid high costs, which can arise in later corrections of the tool after the testing. The presented complex product has been manufactured in several stages, which required implementation of the springback simulations after each operation, as well as a systematic approach for implementation of the surfaces´ compensation in all designing operations of the tool.
