Abstract:V magistrskem delu je predstavljen postopek dimenzioniranja orodja za upogibanje pločevine. Ker se pločevina trajno deformira zaradi plastične deformacije, smo predstavili razliko med inženirskim in dejanskim diagramom napetost – deformacija, na kratko opisali mehanizme plastične deformacije kovin in predstavili tehnološke parametre pri procesu upogibanja pločevine s premočrtnim gibanjem orodja. Na podlagi tehnoloških parametrov smo naredili parametrični model orodja, ki nam je omogočal najenostavnejše spreminjanje dimenzij orodja. Ker je orodje dinamično obremenjeno, smo za dimenzioniranje uporabili napetostno metodo. Izvedli smo numerične simulacije po MKE v programskem paketu Ansys za začetno in končno geometrijo orodja ter primerjali analitično in numerično izračunano dobo trajanja.

Title:Dimensioning of Sheet Metal Bending Tool
Abstract:In this master work we present the process of dimensioning of sheet metal bending tool. Because the sheet metal is during the process of bending permanently deformed, we described the difference between engineering and true stress – strain diagrams, yielding mechanisms and technological requirements of bending process. Based on this requirements, we modeled a parametric tool that allowed us the easiest manipulation of tool dimensions. Because the tools are subjected to dynamic loads, we used the stress life approach for dimensioning. We also made FEM numerical simulations with Ansys for start and end tool geometry and compared analytical and numerical calculated lifetime.
